market cost of the Product used for treatment of such patient in the Clinical Trial, Novartis shall be permitted, at its sole discretion, to provide the Product to the patient free of charge (or at any nominal charge) and shall compensate Prometheus
for each such vial used for such patient at a rate of [* * *] percent ([* * *]%) of the Prometheus Average Net Selling Price in the applicable country in the Territory. Within [* * *] ([* * *]) days after the end of each Calendar Quarter during the
Term, Novartis shall submit to Prometheus a report setting forth the number of vials provided to patients in accordance with this Section 2.8, following which Prometheus shall provide Novartis with an invoice setting forth the applicable
amounts due from Novartis for the applicable Calendar Quarter which shall be due and payable within [* * *] ([* * *]) days of receipt by Novartis.

 (c) In the event that Novartis Excluded Product 1 is approved by the
applicable Regulatory Authorities and Commercialized by Novartis, its Affiliates or their licensees or sublicensees, and as a result of such Commercialization is considered a Third Party Product for the purposes of this Agreement, Prometheus shall
be permitted to offset against any Incremental Product Net Sales Milestone by an amount equivalent to the aggregate amount paid or due to Prometheus from Novartis for vials of Product given to such patients free of charge (or at a nominal fee)
during the development of Novartis Excluded Product 1. For avoidance of doubt, if Commercialized in the Territory, Novartis Excluded Product 1 shall be considered a Third Party Product for purposes of this Agreement even if it is Commercialized by
Novartis, its Affiliates or their licensees; provided that Prometheus shall have the exclusive right in the Territory to Commercialize any Products labeled for use in connection with Novartis Excluded Product 1 during the Term. 
 (d) If Novartis Excluded Product 1 is approved for use by applicable Regulatory Authorities in the Territory in conjunction
with the Product, Prometheus shall use Commercially Reasonable Efforts to update the Product’s label at Novartis’ cost to indicate such non-exclusive usage with Novartis Excluded Product 1. 
 SECTION 3. 
 DEVELOPMENT 
 3.1 Joint Development Committee. 
 (a) Formation. Within thirty (30) days after the Effective Date, the Parties shall establish a joint development
committee (“JDC”) to facilitate co-operation between the Parties with respect to the clinical Development activities that may be undertaken by each Party for the Products. The JDC will be composed of [* * *] ([* * *])
representatives of each Party who shall be appointed (and may be replaced at any time) by such Party on prior written notice to the other Party in accordance with this Agreement. 
 (b) Meetings. The JDC shall meet not less frequently than [* * *] ([* * *]) times per calendar year throughout the

 26 

 
with the requirements of Section 9; provided that, in the case of a consultant or other non-employee representative of a Party or its Affiliates, the other Party’s consent to the
attendance of such consultant or representative must be obtained prior to the JDC meeting. Each Party shall be responsible for its own expenses for participating in the JDC. Meetings of the JDC shall be effective only if at least one
(1) representative of each Party is present or participating. In the event that the JDC cannot reach unanimous agreement on any issue for which the JDC (as opposed to any individual party) has decision-making power under this Agreement, the
matter shall be escalated in accordance with Section 11.1 of this Agreement. Notwithstanding any such escalation of the issue pursuant to Section 11.1, in the event that the designated executives of each Party are not able to resolve the
issue within the scope and time frames set forth in Section 11.1, then neither Party shall have the right to pursue or undertake such matter which is the subject of escalation unless and until the Parties have reached unanimous agreement with
respect thereto. 
 (c) Responsibilities. The JDC shall have the responsibility and authority to:

 (i) Subject to Section 3.2(e), discuss and make decisions regarding the further Development of, or
activities aimed at the purpose of changing the Product in any way, including, the proposed conduct by either Party or its Affiliates of any Clinical Trial for any Improvement to the Product, any New Indication for the Product, any Combination
Product that would require a modification of or supplement to the labeling for the Product or any activities seeking to generate data allowing for Product labeling, formulation or delivery method changes. If Development or other Product Improvement
or requirement is mandated by a Regulatory Authority in relation to the Product, both Parties agree that such mandated Development, Improvement or other requirement must be implemented and one Party shall not have the authority to block the other
Party from performing the necessary activities to comply with the Regulatory Authority’s mandate; provided that each Party shall cooperate with the other Party in good faith to minimize the potential adverse effects of any such mandated
activities. 
 (ii) Subject to Section 3.2(e), discuss and make decisions regarding the conduct of any
investigator-initiated Clinical Trials commenced by Novartis or its Affiliates prior to the Effective Date or planned for initiation by Novartis or its Affiliates following the Effective Date, in each case solely as set forth on
Exhibit L attached hereto (the “Investigator-Initiated Trials”). 
 (iii) Perform
such other functions as the Parties may agree in writing. 
 3.2 Development and Regulatory Activities and
Responsibilities. 
 (a) Novartis Responsibilities. Promptly following the Effective Date, in the case

the United States) or

  

 27 

 
fourteen (14) days after the Canada Election Date (in the case of Canada), as applicable, Novartis shall deliver to Prometheus, electronically and in hard copy, executed letters (in mutually
acceptable form) addressed to the applicable Regulatory Authorities requesting the transfer, to the extent transferable, of the Regulatory Approvals listed on Exhibit F, from Novartis to Prometheus. Novartis shall use Commercially Reasonable
Efforts to transfer and assign to Prometheus as soon as reasonably practicable following the applicable Regulatory Transfer Commencement Date all such Regulatory Approvals and any other Regulatory Approvals held by Novartis or its Affiliates as of
the Effective Date. Furthermore, Novartis shall be solely responsible for, and bear all costs associated with, generating, preparing and providing to Prometheus, in accordance with Section 2.4(a) for the United States, and within twenty
(20) Business Days following the applicable Regulatory Transfer Commencement Date for Canada, a copy of all Dossiers which Novartis reasonably determines are required by Prometheus in order to perform its rights and obligations pursuant to
Section 3.2(b). During the Term, Novartis shall cooperate with Prometheus at Prometheus’ cost in connection with the performance by Prometheus of its rights and obligations under Sections 3.2(b) and (c), and shall execute, acknowledge
and deliver such further instruments and do such other acts and provide such other information at Prometheus’ reasonable request and expense, which are necessary and reasonably requested for Prometheus to obtain and maintain all required
Regulatory Approvals with respect to the Territory. Notwithstanding the foregoing, Novartis shall not be obligated to provide any Manufacturing Know-How or other manufacturing information other than that expressly identified in this Agreement or the
Supply Agreement. For the avoidance of doubt, all rights, interests and title in and to the Dossier(s) shall remain with and be solely owned by Novartis. 
 (b) Prometheus Responsibilities. Prometheus shall be responsible for, and bear the cost of (i) obtaining and maintaining all Additional Regulatory Approvals which are necessary for Prometheus
to Develop and Commercialize the Products in the Territory, and (ii) maintaining and submitting renewals for all required Regulatory Approvals that are transferred and assigned to it by Novartis in accordance with Section 3.2(a), but
excluding any manufacturing establishment fees, which shall be the sole responsibility of Novartis. For the avoidance of doubt, all rights, interests and title to all Regulatory Approvals transferred and assigned to Prometheus in accordance with
Section 3.2(a) and all Additional Regulatory Approvals obtained by Prometheus in accordance with this Section 3.2(b) shall be solely owned and held in the name of Prometheus during the Term, subject to Prometheus’ obligations to
maintain, in good standing, the Regulatory Approvals in the Territory during the Term and to transfer and assign all such Regulatory Approvals over to Novartis following termination or expiration of this Agreement in accordance with
Section 10.7(e). 
 (c) Prometheus Control of Regulatory Activities. Subject to Section 3.2(e)
and the other terms and conditions of this Agreement, Prometheus shall be responsible and have final decision-making authority, as to whether and how to obtain, supplement, amend or otherwise alter the Regulatory Approvals for Commercialization of
the Products in the Territory, for communicating with any Regulatory Authorities in the Territory with respect to Regulatory Approvals held in Prometheus’ name regarding the Commercialization of the Products in the Territory, and otherwise with
respect to any

  

 28 

 
issues raised by any Regulatory Authorities in connection with Prometheus’ Commercialization of the Products in the Territory. Furthermore, Prometheus shall have the right to communicate
with any Regulatory Authorities in the Territory with respect to any issues raised in connection with any Development of the Products in the Territory by Prometheus which has been approved by the JDC, except that all final decision-making authority
with regard to the Development of the Products remains with the JDC or as otherwise expressly set forth under this Agreement. Notwithstanding the foregoing, to the extent applicable to the Product and permitted by Applicable Law, Prometheus will
communicate to Novartis, and provide Novartis with copies of all material communications proposed to be submitted by Prometheus to any applicable Regulatory Authority if and as soon as reasonably practicable after their preparation, including any
applications or other communications with regards to obtaining Regulatory Approvals, following which Novartis shall, if reasonably practical, have a period of ten (10) days to provide comments on such communications to Prometheus. Prometheus
shall consider such comments in good faith, but shall have final decision-making authority as to whether to incorporate such comments into its final communications. Prometheus shall provide copies of all final written material communications between
Prometheus and any Regulatory Authority to Novartis within a reasonable period of time following such communication. 
 (d) Notification of Breach of Applicable Law. In the event that either Party receives notice or otherwise becomes aware of any alleged or actual violation of Applicable Law related to the Development or Commercialization of the
Products in the Territory, whether received from any Regulatory Authority or otherwise, the receiving Party shall promptly provide written notice of the same to the other Party together with copies of any material notices or communications in
connection therewith. 
 (e) Conduct of Development and Regulatory Activities for Product Improvements or New
Indications. 
 (i) The Parties acknowledge and agree that during the Term, neither Party shall have the
right to conduct or perform any Clinical Trials and/or seek any Regulatory Approvals with respect to Improvements to or New Indications for or uses of the Products in connection with either Party’s Development activities without first obtaining
the prior written approval of the other Party. It is understood that such approval may be conditioned by the other Party on having reached agreement with respect to modified financial terms or other provisions applicable to such Improvement or New
Indication. 
 (ii) Without limiting the foregoing, notwithstanding anything to the contrary set forth herein
(other than the exclusions applicable to the Novartis Excluded Products), neither Party shall (A) commence Development of any Improvement to a Product, any New Indication for a Product, any Combination Product that would require a modification
of or supplement to the labeling for the Product or any activities seeking to generate data for the purpose of obtaining a change to the Product labeling, or (B) seek any Additional Regulatory Approval for an Improvement to a Product or a New
Indication or use for the Product,

  

 29 

 
without the prior written consent of the JDC. Notwithstanding anything to the contrary set forth herein, Novartis reserves all rights, and the JDC shall have no authority, with respect to
(i) Improvements or modifications to be made to any manufacturing processes; and (ii) any updates or upgrades to be made with respect to manufacturing facilities; provided that where and to the extent any updates, Improvements or
modifications contemplated by the foregoing subsections (i) and/or (ii) cover or relate to the Products or the Product Intellectual Property, are reasonably likely to have an adverse impact upon the Regulatory Approvals in the Territory,
or materially increase Prometheus’ obligations in connection therewith, such matters shall be subject to review and agreement by the JDC. 
 (f) Material Transfer Agreements and Investigator-Initiated Trials. Commencing on the First Sales Booking Date, and so long as Prometheus is contractually and legally able to do so prior to any
assignment of the relevant Investigator Initiated Trial agreements and/or MTA, Prometheus shall bear all responsibility for managing the Investigator-Initiated Trials set forth on Exhibit L, and the studies and trials contemplated by the
Material Transfer Agreements (collectively, the “MTA”) set forth on Exhibit L through the completion of such studies and trials, including making all payments that are due thereunder on or after the First Sales Booking Date
and managing the relationships with the investigators with respect to each such individual study or trial. Novartis shall assign, and Prometheus shall assume, all of the MTAs and the underlying agreements with respect to the studies and trials,
including the Investigator-Initiated Trials, set forth on Exhibit L as soon as reasonably practicable after the Effective Date, but no later than [* * *] ([* * *]) days after the Effective Date. Novartis shall supply the Products for
such studies and trials until the date that the Parties shall enter into an agreement with respect to such supply under this subsection (f), which agreement shall be negotiated in good faith by the Parties and entered into by the Parties as soon as
reasonably practicable after the Effective Date, but no later than [* * *] ([* * *]) days after the Effective Date. Prior to the date that the Parties have entered into such supply agreement, Novartis shall have the sole obligation to supply the
Products for such studies and trials. After the date that the Parties have entered into such supply agreement, Prometheus shall have the sole obligation to supply the Products for such studies and trials. The Parties agree that notwithstanding the
foregoing (i) Novartis shall bear the costs of supplying the Products for the studies and trials that are specifically set forth on Exhibit L; and (ii) the Parties shall [* * *] in connection with such studies and trials set
forth on Exhibit L as of the First Sales Booking Date, which Out-of-Pocket Costs shall be first processed and paid in full by Prometheus, and then invoiced by Prometheus to Novartis for reimbursement of [* * *]
([* * *]%) of such Out-of-Pocket Costs. For the avoidance of doubt, Prometheus shall receive no compensation with respect to Products supplied to conduct the foregoing studies and trials or to meet the obligations of the MTA or other

provide a study report for such Phase IV Clinical Trial to Prometheus for Prometheus to submit to the FDA. Novartis shall supply the Products for such Phase IV Clinical Trial until the date that the Parties shall enter into an agreement with respect
to such supply under this subsection (g), which agreement shall be negotiated in good faith by the Parties and entered into by the Parties as soon as reasonably practicable after the Effective Date, but no later than [* * *] ([* * *]) days after the
Effective Date. After the date that the Parties have entered into such supply agreement, Prometheus shall have the sole obligation to supply the Products for such Phase IV Clinical Trial. Notwithstanding the foregoing, the Parties agree that solely
with respect to such Phase IV Clinical Trial commitment set forth on Exhibit X, Novartis shall bear the costs of supplying the Products for such Phase IV Clinical Trial. For the avoidance of doubt, Prometheus shall receive no compensation
with respect to the supply of the Products to conduct the foregoing Phase IV Clinical Trial.

 32 

 
such orders. In accordance with the terms and conditions set forth on Exhibit S, Novartis shall provide certain Transition Services as set forth in Exhibit S to Prometheus
concerning the transition of the Commercialization of the Products to Prometheus in a commercially reasonable manner, provided that the transition services shall not continue for a period longer than three (3) months after the Effective

 (b) NDC and Labeling Transition. On or before
the First Sales Booking Date, Prometheus shall provide to Novartis its five (5) digit NDC labeler code to be used to establish the ten (10) digit NDC and the Parties shall mutually agree on the ten (10) digit NDC number for Product to
be sold by Prometheus hereunder (or any foreign equivalent thereof, the “Prometheus NDC”). Prometheus will distribute the Product intended for consumption in the United States under Novartis’ and its Affiliates’ NDC
numbers (or any foreign equivalent thereof, the “Novartis NDC”) and with labeling and packaging incorporating the Novartis Brands for a mutually agreed period after the First Sales Booking Date, until Novartis is able to supply
Product bearing the Prometheus NDC and labeling and packaging which does not incorporate any Novartis Brands, anticipated to be approximately six (6) months after the First Sales Booking Date. 
 (c) Patient Assistance Programs. As soon as reasonably practicable following the Effective Date, but no later than one
hundred and twenty (120) days after the Effective Date (the “PAP Transition Period”) and for the remainder of the Term, Novartis shall supply the Products to Prometheus’ designated vendor/service provider who will
coordinate patient assistance programs on behalf of Prometheus. During the PAP Transition Period, Novartis shall continue to supply Product to all patients enrolled in existing patient assistance programs established by Novartis and its Affiliates
for the Products as of the Effective Date. During the PAP Transition Period, (i) the Parties shall cooperate in good faith with regards to the transfer of Novartis and its Affiliates’ obligations under existing patient assistance programs
to Prometheus; and (ii) Novartis shall provide transition support, including, if permitted and desired by Prometheus, the assignment of its existing agreement(s) with Third Party vendors with regards to its existing patient assistance programs
to Prometheus. Upon the expiration of the PAP Transition Period or on such earlier date as the Parties shall mutually agree (the “PAP Transition Date”), Novartis shall refer all new patients interested in participating in patient
assistance programs relating to the Products in the Territory to Prometheus and shall have no obligations or responsibilities with regards to patient assistance programs relating to the Products in the Territory except for supplying the patient
assistance program vendor/services provider with Products as contemplated herein. As of the PAP Transition Date and thereafter during the Term, Prometheus shall ensure that all patients in existing patient assistance programs of Novartis and its
Affiliates shall continue to receive the Products as their needs require in accordance with the established criteria for the Product patient assistance programs. After the PAP Transition Date and during the Term, Prometheus will offer a patient
assistance program for indigent patients who have been prescribed the Products. Prometheus shall have the discretion to modify the Product patient assistance program criteria in its reasonable discretion, provided, however, that
(i) any patients enrolled as of the PAP Transition Period shall continue to be determined eligible for the Prometheus Product patient assistance program based on the Novartis

  

 33 

 
patient assistance program criteria, unless the Prometheus criteria are more generous/less restrictive; and (ii) Prometheus shall not materially modify the eligibility criteria for patients
to participate in the patient assistance programs relating to the Products so as to make it materially more difficult for patients to qualify without Novartis’ prior written consent, such consent not to be unreasonably withheld, conditioned or
delayed. Prior to the Effective Date Novartis has provided to Prometheus the relevant Novartis eligibility criteria for patient participation/enrollment in the Novartis patient assistance program for the Existing Product. Prometheus shall continue
during the Term to enroll new patients into such patient assistance programs, including any patients referred to Prometheus from key patient referral centers as identified by Novartis to Prometheus during the PAP Transition Period. Upon the PAP
Transition Date and thereafter, Prometheus shall be liable for all administrative, reporting and related responsibilities with respect to such patient assistance programs. Novartis shall supply the Products to the applicable vendors/services
providers for such patient assistant programs until the date that the Parties shall enter into an agreement with respect to such supply under this Section 4.2(c), which agreement shall be negotiated in good faith by the Parties and entered into

obligation to supply the Products to the applicable vendors/services providers for such patient assistant programs. Notwithstanding the foregoing, Novartis shall bear the costs of supplying the Products for the applicable vendors/services providers
for the patient assistance programs set forth under this Section 4.2(c). For the avoidance of doubt, Prometheus shall receive no compensation with respect to any and all Products supplied with respect to such patient assistance programs.

Prometheus a non-exclusive license during the Term in the Field in the Territory to update, adapt, use and create derivative works of such Novartis Promotional Materials to design and create the Prometheus Promotional Materials; provided that
this license is being granted only under any copyright of Novartis in the Novartis Promotional Materials and does not grant any license or right to use any Novartis Brands or other Intellectual Property of Novartis included in any Novartis

other equivalent Regulatory Authorities in all such other countries of the Territory where Regulatory Approvals for the Products have been obtained, advising such Regulatory Authorities that Prometheus will be the sole marketer and promoter of the
Products in the applicable country in the Territory commencing on the First Sales Booking Date and requesting that such Regulatory Authorities address regulatory inquiries and concerns regarding Prometheus’ Promotional Activities solely with
Prometheus. Subject to Prometheus’ obligation to provide copies of

  

 35 

 
material correspondence with Regulatory Authorities in accordance with this Section 4.3(b) or as otherwise provided herein, Prometheus will not be required to notify Novartis of any
Promotional Activities. 
 4.4 Use of Trademarks and Trade Dress. During the Term, and subject to the terms and
conditions of this Agreement: 
 (a) Prometheus will Commercialize the Products in the Territory under the
Product Marks and will not identify any Product by any designation other than the Product Marks; provided that Prometheus may identify itself as distributor of the Products and the labeling for the Products and the Prometheus Promotional
Materials may contain the Prometheus corporate name and logo in accordance with the Product labeling requirements set forth in the Supply Agreement. From time to time, Prometheus may propose to Novartis that an additional Trademark be used in
connection with the Commercialization of the Product in the Territory (each an “Additional Product Mark”). No Additional Product Mark shall be used in connection with the Commercialization of the Product in the Territory unless and
until Novartis approves such Additional Product Mark for use in connection with the Commercialization of the Product in writing in advance. Any Additional Product Mark so approved by Novartis shall be deemed to be a Product Mark for purposes of this
Agreement, and Prometheus hereby assigns to Novartis any right, title and interest in and to any such Additional Product Marks. Prometheus will use the Product Marks and Product Trade Dress solely with respect to the Products purchased from Novartis
or its designee as provided in this Agreement. 
 (b) During the Term, whenever Prometheus uses the Product Marks
in any Prometheus Promotional Materials or in any other manner in connection with any Product, Prometheus will clearly indicate that the Product Marks are owned by the Novartis group of companies pursuant to a notice approved by Novartis. When using
the Product Marks and Product Trade Dress under this Agreement, Prometheus will comply with all Applicable Law pertaining to the Product Marks and Product Trade Dress in force at any time in any jurisdiction in the Territory where Prometheus is
Commercializing the Products. 
 (c) Prometheus acknowledges and agrees that Novartis and/or its Affiliates, is,
and at all times will remain the owner of the Product Marks and Product Trade Dress during the Term and that all use of the Product Marks and Product Trade Dress by Prometheus or its Sublicensees shall inure to the benefit and be on behalf of
Novartis and/or its Affiliates. Prometheus will not at any time knowingly do, or knowingly cause to be done, or permit its Affiliates or Sublicensees or any of its or its Affiliates’ or Sublicensees’ employees, agents, contractors and
subcontractors to commit any act inconsistent with, contesting or in any way impairing, or tending to impair, such ownership. 
 (d) Notwithstanding any license granted hereunder or any other provision granting Prometheus a right or license to use any Product Intellectual Property, any such right or license granted hereunder to use
such Product Intellectual Property is limited in connection with use on or in connection with the Internet as follows: (i) all use in

  

 36 

 
connection with the Internet must be in compliance with Applicable Law regarding sale, distribution, and advertising of the Products on the Internet; (ii) Prometheus hereby receives an
exclusive license during the Term and subject to the terms hereof to use and maintain the domain name www.proleukin.com, and, as of the Canada Election Date, www.proleukin.ca, and any other domain names incorporating the Products Marks which are

sites located at such domain names in accordance with Section 4.3(a); and (iii) Prometheus shall be entitled to use the Product Intellectual Property on the Internet or on any similar online interactive media only on the Product Websites;
provided that the content on any such Product Websites shall target only audiences in the Territory and Prometheus shall not knowingly consent to links to such Product Websites that may originate outside the Territory without the prior
written consent of Novartis and shall promptly notify Novartis of any such links of which it becomes aware and remove such links upon Novartis’ request. Prometheus shall include on any websites permitted hereunder prominent disclaimers
notifying visitors to the sites that they are intended only for residents within the Territory. Prometheus shall host the Product Websites on its own server or retain a Third Party to do so. Except as provided in this paragraph, Prometheus shall not
use the Product Intellectual Property on or in connection with the Internet or any similar online interactive media. In addition to the foregoing, Prometheus shall not register or use a new domain name that incorporates a Product Mark unless and
until Novartis approves such domain name for use in connection with the Commercialization of the Product in writing in advance. Any such approved domain name shall be registered in the name of Novartis or its Affiliates, and Prometheus hereby
assigns to Novartis any right, title and interest in and to any such domain name, provided that such domain name shall be licensed to Prometheus as a Product Website in accordance with this Section 4.4. Prometheus shall also limit use of
the INN “aldesleukin” on or in connection with the Internet to the same extent and upon the same terms as are set forth above with respect to a Product Mark. 
 (e) Notwithstanding anything to the contrary set forth in this Agreement, nothing in this Agreement grants to Prometheus or
any of its Affiliates or Sublicensees any rights or licenses to use any Trademarks or names of any Upstream Licensors or any of their respective inventors and Affiliates. Prometheus and its Affiliates and Sublicensees shall not use the name of any
inventor of the Upstream Licensed Product Patent Rights, or any institution with which he or she has been or is connected, or any Upstream Licensor and its Affiliates, or any adaptation of any of them, in any advertising, promotion or sales

Prometheus shall use all Product Marks and Product Trade Dress in accordance with Novartis’ Trademark Guidelines set forth on Exhibit R. Novartis or its authorized representatives shall have the right to inspect at any time during normal
business hours and after reasonable notice, the business premises of Prometheus and its Affiliates to ensure that the character and quality of the goods used or services offered in association with the Trademarks are in compliance with the terms of
this Agreement. Prometheus will, upon the request of Novartis, supply to Novartis or its authorized

  

 37 

 
representatives, samples of the goods in association with which it uses any such Product Marks and Product Trade Dress. To the extent Prometheus may be permitted hereunder to sublicense its
rights in connection with the Product Marks and Product Trade Dress, it shall impose on any Sublicensee the duties and obligations imposed hereunder in this Section 4.5. 
 4.6 Pricing and Sales Terms. During the Term, Prometheus will have the sole authority to determine the prices of the Products sold by
it and to establish its own terms and conditions of sale and pricing policies for the Products in the Territory, including price increases or decreases and the timing thereof, subject to complying as of the First Sales Booking Date and thereafter
with the terms and conditions of those existing agreements with the group purchasing organizations, managed health care organizations or similar entities set forth in Section 1 of Exhibit U and that shall (subject to the terms of
Section 11.17) be assigned by Novartis in whole or in part to Prometheus, and shall be assumed in whole or in part, as applicable, by Prometheus, pursuant to an Assignment and Assumption Agreement in the form attached in Section 2 of
Exhibit U (“Existing Discount Agreements”). Notwithstanding the foregoing, Prometheus shall not be required to assume any Existing Discount Agreement if the terms of such Existing Discount Agreement as they relate to the
Products were not disclosed to Prometheus prior to the First Sales Booking Date. 
 4.7 Rebates and Chargebacks.

 (a) Government Rebates. Novartis shall process and be financially responsible for all rebates pursuant
to any government rebate programs for all Product payable to State Medicaid Agencies and State Assistance Programs with a Novartis NDC prior to the Processing Handover Date. If the Processing Handover Date is not at the start of a Calendar Quarter,
the quarterly rebates will be billed to Prometheus based on a ratio of days that Prometheus is financially responsible (i.e. if the Processing Handover Date is February 11, 2010, the rebates billed Prometheus would be fifty-three and one
third percent (53.33%) of 1Q2010 claimed amounts. The fifty-three and one third percent (53.33%) is based on Prometheus’ responsibility for forty-eight (48) days out of ninety (90) days in the Calendar Quarter). The claimed
Calendar Quarter shall be based on the Calendar Quarter claimed in the rebate submissions by the respective states or the District of Columbia without regard to dispensing date since State Medicaid claims are based on when the state reimburses the
pharmacy and not the dispensing date. For Product claimed with a Novartis NDC on or after the Processing Handover Date, Novartis shall continue to process government rebates, and Prometheus will reimburse Novartis for all such rebates. Prometheus
will also be responsible for utilization changes and rebate changes (associated AMP and “best price” (as defined in the Medicaid Prescription Drug Improvement and Modernization Act of 2003) changes) related to the time period after the
Processing Handover Date. Prometheus shall process and be financially responsible for all rebates pursuant to State Medicaid Agencies and State Assistance Programs related to Product labeled with a Prometheus NDC. Novartis shall provide Prometheus
with quarterly corresponding utilization summary reports within ninety (90) days after the end of the applicable Calendar Quarter that describe the requested payments in reasonable detail. If it is determined that Novartis owes Prometheus
monies for rebates pursuant to State Medicaid Agencies and State Assistance Programs based on resubmissions or rebate changes related to claims after or on the Processing Handover Date, Novartis will pay Prometheus with the corresponding utilization
summary reports, upon receipt of invoice issued by Prometheus. 
  

 38 

 (b) Commercial Rebates. Novartis shall process and be financially
responsible for all commercial rebates related to Product sold by Third Parties until the First Sales Booking Date; provided, however, that Prometheus shall reimburse Novartis for all commercial rebates related to the Product sold in
connection with any of the agreements set forth in Section 1 of Exhibit U which are for sales booked by Prometheus on or after the First Sales Booking Date but before the date of assignment of the applicable agreement set forth in
Section 1 of Exhibit U pursuant to Section 4.6 above. Prometheus shall process and be financially responsible for all commercial rebates related to Product sold by Third Parties on or after the First Sales Booking Date. To the
extent that a Party processes, issues credits or remits payment for commercial rebates in respect of Product for which the other Party is financially responsible under this Section 4.7(b), such Party shall provide the other Party with monthly
reports within sixty (60) days after the end of the applicable month setting forth in reasonable detail the amount of all such issued credits or remitted payments, and (i) with respect to all amounts owed by Novartis to Prometheus,
Prometheus shall submit an invoice to be paid by Novartis within sixty (60) days after Novartis’ receipt of such invoice, and (ii) with respect to all amounts owed by Prometheus to Novartis, Prometheus shall pay such amounts to
Novartis together with its next payment of Royalties in accordance with Section 5.6. 
 (c) Chargeback
Claims. Novartis shall process and be financially responsible for all chargeback claims related to Product sold by Third Parties with a ship date/invoice date on or before January 31, 2010, and Prometheus shall process and be financially
responsible for all chargeback claims related to Product sold by Third Parties with a ship date/invoice date on or after February 1, 2010. Notwithstanding the foregoing, the Parties acknowledge that the VA National Acquisition Center must
approve the removal of the Product from Novartis’ Federal Supply Schedule (“FSS”). Prometheus shall work with Novartis to coordinate the addition of the product to the Prometheus FSS to coincide with Novartis removing the
product from the Novartis FSS. Novartis and Prometheus will coordinate the addition and removal of the Product from the FSS so the switch over occurs as close to January 31, 2010 as possible, with consideration to FSS regulations. Prometheus
and Novartis agree that Novartis shall have no financial liability for chargeback claims with a ship date/invoice date after January 31, 2010. To the extent that a Party processes, issues credits or remits payment for chargeback claims in
respect of Product for which the other Party is financially responsible under this Section 4.7(c), such Party shall provide the other Party with monthly reports within sixty (60) days after the end of the applicable month setting forth in
reasonable detail the amount of all such processed chargeback claims, and (i) with respect to all amounts owed by Novartis to Prometheus, Prometheus shall submit an invoice to be paid by Novartis within sixty (60) days after Novartis’
receipt of such invoice, and (ii) with respect to all amounts owed by Prometheus to Novartis, Prometheus shall pay such amounts to Novartis together with its next payment of Royalties in accordance with Section 5.6.

 4.8 Government Pricing Information. 
 (a) With respect to Product sold by Prometheus after the First Sales Booking Date that bears a Novartis NDC, Prometheus will
deliver and certify to Novartis, as established by the Final Rule to Implement Medicaid Drug Pricing and Reimbursement Provisions of the Deficit Reduction Act of 2005, within fifteen (15) calendar days after the end of each Calendar Quarter or
reporting period as designated by CMS to include the following information: (i) on a quarterly basis, the “best price” (as defined in the Medicaid Prescription Drug Improvement and Modernization Act of 2003) for all Product,
identified by NDC number, in the format set forth in Exhibit V; (ii) on a monthly and quarterly basis, the average manufacturer price (“AMP”) (as defined under the Social Security Act, 42 USC § 1396r-8(k)(1))
and the relevant summarized units and dollars for AMP calculation components such as Gross Sales, Non-Retail Chargeback Sales, Retail Chargebacks, etc, and AMP eligible sales dollar amounts, as well as the number of AMP eligible units for all of
such Product, each identified by NDC number, in the format set forth in Exhibit V; and (iii) on a quarterly basis, the Manufacturer’s Average Selling Price (“ASP”) (as defined in the Medicaid Prescription Drug
Improvement and Modernization Act of 2003) and the relevant summarized units and dollars for ASP calculation components such as Gross Sales, Non-Government Retail Chargeback Sales, Retail Chargebacks, etc, and ASP eligible sales dollar amounts, as
well as the number of ASP eligible units for all of such Product, each identified by NDC number, in the format set forth in Exhibit V. 
 (b) For existing, if any, or new patient assistance programs or patient transaction programs (card/voucher/coupon), Prometheus agrees to ensure that, with respect to Third Party vendors whose agreements
have been assigned by Novartis pursuant to Section 4.2(c), each such Third Party vendor shall continue to provide patient transaction data that bears a Novartis NDC and is required for government pricing calculations, as previously agreed with
such Third Party vendor under pre-established data feeds and layouts as set forth in Exhibit W. 
 (c)
Novartis agrees to provide Prometheus with any government mandated prices that Prometheus cannot calculate based off the Processing Handover Date. Novartis will provide Prometheus with two Calendar Quarters of PHS pricing after the Processing
Handover Date and 2010 FSS pricing. The Parties agree that each Party may use all information described in this Section 4.8 in reporting to the CMS and other government agencies. The Parties further agree that all Medicaid pricing data
described in this Section 4.8(c) that is included in any report to the other Party will be calculated utilizing systems, processes, policies, practices and pricing methodologies that comply with the requirements of the Medicaid Rebate Law, the
Medicaid Regulations, the applicable Medicaid agreement, if any, the Secretary of Health and Human Services and applicable CMS Medicaid rebate program releases. 
 (d) Novartis will provide Prometheus with Medicaid pricing data for the Product required to support continued filings with
CMS after the transition to Prometheus NDC number, including, Base Date Average Manufacturer’s Price as defined under the Medicaid Rebate Law.

 4.9 Product Returns and Customer Complaints. 
 (a) As of the First Sales Booking Date, Prometheus shall process all returns of any Product, including issuing payment for
such returns to the applicable customer that are made in compliance with Prometheus’ returned goods policy, irrespective of the NDC number (or foreign equivalent) or seller. Prometheus shall bear the costs of all returns of Product that are
under a Prometheus NDC. With regards to returned Product under a Novartis NDC, each Party shall bear the cost of returns on Products which it sold, and all reasonable measures (including lot identification) will be taken to identify which Party was
responsible for selling such returned Product under a Novartis NDC. Notwithstanding the above, Novartis will only be financially responsible for returns of the Product under a Novartis NDC if such returns will have been returned in compliance with
Prometheus’ returned goods policy, and Novartis will base any return credit for such Products on the Novartis [* * *] ([* * *]%). To the extent that a Party processes, issues credits or remits payment for returns in respect of Products for
which the other Party is financially responsible under this Section 4.9(a), such Party shall provide the other Party with monthly reports within sixty (60) days after the end of the applicable month setting forth in reasonable detail the
amount of all such issued credits or remitted payments for returns, and (i) with respect to all amounts owed by Novartis to Prometheus, Prometheus shall submit an invoice for such amounts to Novartis to be paid within sixty (60) days
thereafter, or (ii) with respect to all amounts owed by Prometheus to Novartis, Prometheus shall pay such amounts to Novartis together with its next payment of Royalties in accordance with Section 5.6. Returned Product shall not be
transferred between the Parties, but instead shall be destroyed by the receiving Party. Each Party shall destroy, or cause to be destroyed, all such returned Product in a manner consistent with Applicable Law, and the costs of such destruction shall
not be reimbursed. 
 (b) Neither Party shall instruct, recommend or attempt to induce Customers who have
previously purchased Product from it to (i) return such Product when that would not otherwise have been the case but for such Party’s instructions, recommendations or inducement or (ii) delay the return of such Products. For the
avoidance of doubt, Prometheus’ shipment units of Products to Customers in the ordinary course will not be deemed to violate this Section 4.9(b). 
 (c) For the period from the Effective Date up to the First Sales Booking Date, Novartis will continue to provide all customer service at a level comparable to that which was provided prior to the
Effective Date. On and from the First Sales Booking Date, through the completion of the Term, Prometheus shall assume all customer service responsibility and provide all customer service required by its Customers with respect to the Products. As of
the First Sales Booking Date, and through the completion of the Term, all customer service requests relating to the Product coming to Novartis will be referred to Prometheus at the following contact information:

 4.10 Pharmacovigilance. 
 The Parties have entered into a Pharmacovigilance Agreement as of the Effective Date. Such Pharmacovigilance Agreement shall govern each
Party’s respective obligations with respect to adverse event reporting, monitoring, maintenance of safety databases and submissions to Regulatory Authorities and other similar obligations with respect to the Products. 
 4.11 Sales Force. 
 (a) Promptly following the Effective Date, and in any event no longer than thirty (30) days thereafter, Novartis shall disclose to Prometheus, or provide Prometheus with representational samples of
Product-specific training materials in Novartis’ possession or control which are actively used by Novartis for its training purposes in connection with the Products as of the Effective Date (“Novartis Training Materials”) and
which are reasonable in order to train representatives for Detailing the Product. During the Term, Prometheus shall have the right to use the Novartis Training Materials to design and prepare new training materials for use in the training of the
Prometheus Sales Force in Detailing and otherwise Commercializing the Products in the Field in the Territory in accordance with this Agreement (collectively, the “Prometheus Training Materials”). It is understood that the Prometheus
Training Materials may include use of all or a portion of the Novartis Training Materials (other than any Novartis Brands incorporated therein). Accordingly, Novartis hereby grants to Prometheus a non-exclusive license during the Term in the
Territory to update, adapt, use and create derivative works of such Novartis Training Materials to design and create the Prometheus Training Materials; provided that this license is being granted only under any copyright of Novartis in the
Novartis Training Materials and does not grant any license or right to use any Novartis Brands or other Intellectual Property of Novartis included in any Novartis Training Materials. Prometheus shall have no rights to copy, distribute, use, perform
or display the Novartis Training Materials other than for the limited purposes expressly stated in this Section 4.11(a). 
 (b) Novartis shall be responsible for conducting mutually agreed upon initial training support with respect to the Products to Prometheus’ sales trainers at a time and place mutually agreed upon by
the Parties, subject to Prometheus reimbursing Novartis for its Out-of-Pocket Costs for travel associated with its provision of such training, and provided that such initial training support shall occur within the first [* * *] ([* * *])
months after the Effective Date and shall not exceed the amount shown in Exhibit S. 
  
 *** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 42 

 
Notwithstanding the provision of such training materials to Prometheus or the conduct of Prometheus Sales Force training by Novartis, Prometheus alone shall be solely responsible for determining
the appropriateness of such training materials and for ensuring that all Product training for the Prometheus Sales Force complies with Applicable Laws. Ongoing training of Prometheus’ Sales Force will be the sole responsibility of Prometheus at
its cost and expense. For clarification purposes, after the earlier to occur of (i) the conduct of the initial training support and (ii) [* * *] ([* * *]) months after the Effective Date, Novartis shall not have any obligation to provide
any training support to Prometheus. Other than with respect to the initial services and training materials supplied by Novartis as set forth hereunder, the contents of any training provided by Prometheus that relates to the Products will be
developed and coordinated by Prometheus, and Prometheus will be solely responsible for training its Sales Force with regard to Applicable Law and directing such Sales Force personnel to be compliant with Applicable Law. 
 4.12 Minimum Marketing and Promotion Investment. 
 (a) In each Contract Year during the Term, Prometheus shall expend at least the Minimum Marketing Spend in support of its
Commercialization of the Products in the Field in the Territory in accordance with this Agreement (as set forth on Exhibit H); provided that with respect to any expenditure on promoting the Products made by Prometheus in excess of the
Minimum Marketing Spend in any Contract Year, such excess amount may be carried over to the next Contract Year up to an amount not to exceed [* * *] percent ([* * *]%) of the next Contract Year’s Minimum Marketing Spend. 
 (b) In the event that in any Contract Year during the Term, Prometheus expends greater than or equal to [* * *]
percent [* * *]%) of the Minimum Marketing Spend for such Contract Year but [* * *], then Prometheus [* * *], and such failure to satisfy the Minimum Marketing Spend shall not [* * *]. 
 (c) In the event a Significant Market Event occurs during any Contract Year during the Term, the Minimum Marketing Spend and
the Minimum Detail Requirements shall be reduced on a pro rata basis for the period of time during the applicable Contract Year which is affected by such Significant Market Event (for example, if such Significant Market Event lasts for thirty
(30) days, then the Minimum Marketing Spend and the Minimum Detail Requirements would be reduced by 30/365 (or 30/366 in a leap year)). 
 (d) Within forty-five (45) days after the end of each Calendar Quarter during the Term following the First Sales Booking Date, Prometheus shall prepare and deliver to Novartis a report setting out
the amount of its M&S Expenses incurred in marketing, Detailing (including, in sufficient detail to allow for Novartis to determine the number of Details to Tier 1 and Tier 2 physicians, as well as the number of Primary Product Details and
Secondary Product Details to such Tier 1 and Tier 2 physicians) and promoting the

 43 

 
Products in the Field in the Territory during the previous Calendar Quarter. In addition, within forty-five days after the end of each Calendar Quarter in which the last day of the applicable
Contract Year shall occur, Prometheus shall provide a report setting out the total amount of its M&S Expenses incurred for such Contract Year. Novartis shall be entitled, at its own expense, to audit Prometheus’ books and records in
accordance with Section 5.7 for the purposes of determining Prometheus’ compliance with its Minimum Marketing Spend obligations for the applicable Contract Year in which such Calendar Quarter falls. 
 (e) In each Contract Year, Prometheus shall meet at least the Minimum Detail Requirements in the Field in support of its
Commercialization of the Products in the Territory. For purposes of the Minimum Detail Requirements specified in Exhibit H to this Agreement, it shall only be considered to be a Detail to the extent that such Detail is a Primary Product
Detail or a Secondary Product Detail. 
 SECTION 5. 
 PAYMENTS 
 5.1 Up-front Payment. 
 (a) Prometheus Up-Front Payment. In consideration of Novartis entering into this Agreement, on or prior to
December 30, 2009, Prometheus shall pay to Novartis a non-refundable up-front payment of one hundred eighty five million U.S. dollars ($185,000,000) (the “Up-Front Payment”). 
 (b) Sublicense Payments. In consideration of Novartis entering into this Agreement and subject to the terms and
conditions stated herein, Novartis shall receive [* * *] percent ([* * *]%) of the amount or value of any upfront or milestone payments or other rights (including rights to any Third Party or “quid” product) received by Prometheus or its
Affiliates from a Sublicensee in connection with or as a consideration for the grant of, a Sublicense; provided that in the case of other rights received by Prometheus, in the event that the Parties cannot agree upon the appropriate valuation
of such rights, such matter shall be referred to a mutually acceptable Third Party expert with relevant pharmaceutical product valuation experience for a final and binding determination of the value of the applicable rights. In the event that the
Parties, after good faith discussions and consideration, cannot agree upon the Third Party expert, then each Party shall individually appoint a Third Party expert with relevant pharmaceutical product valuation experience and these Third Party
experts shall, in turn, appoint a Third Party expert with relevant, similar experience. The three Third Party experts shall then perform the valuation contemplated by this Section 5.1(b) and shall, together, make a final and binding
determination of the value of the applicable rights. For the avoidance of doubt, the following amounts received by Prometheus from its Sublicensees are deemed not to be upfront or milestone payments the subject of this Section 5.1(b):

  
 *** Certain information on this page has been omitted and filed
separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 44 

 
(i) equity investments made by, or loans granted by, the Sublicensee to Prometheus at fair market value in the course of further financing Prometheus, and (ii) payments made by the
Sublicensee to Prometheus to reimburse Prometheus, at fair market value, for its actual, reasonable and documented costs in performing activities or services in connection with the Sublicense granted on the Products. 
 5.2 Royalties. In consideration of Novartis entering into this Agreement and subject to the terms and conditions stated herein,
Prometheus shall pay Novartis a royalty (“Royalty”) on Net Sales of the Products at the royalty rate calculated in accordance with the provisions below, subject to a reduction, if any, as set forth in Section 5.4. 

(a) [* * *] percent ([* * *]%) of aggregate Net Sales of the Products in the Territory in each calendar year up to and
including [* * *] U.S. dollars ($[* * *]); 
 (b) [* * *] percent ([* * *]%) of aggregate Net Sales of the
Products in the Territory in each calendar year above [* * *] U.S. dollars ($[* * *]) up to and including [* * *] U.S. dollars ($[* * *]); and 
 (c) [* * *] percent ([* * *]%) of aggregate Net Sales of the Products in the Territory in each calendar year above [* * *] U.S. dollars ($[* * *]). 
 Notwithstanding anything to the contrary set forth herein, in the event that there are Net Sales on Products manufactured by an Alternate
Manufacturer (as that term is defined in the Supply Agreement), the Royalty to be paid by Prometheus with respect to such Net Sales shall be the Royalty rates set forth above plus [* * *] percent ([* * *]%) (i.e., [* * *] percent ([* * *]%)
shall be added to each tier of Royalties described above). The annual Net Sales of the Products set forth above shall be measured from the beginning of each calendar year (or from the First Sales Booking Date for the first calendar year of the
Term), and the royalty rates set forth above shall re-set at the beginning of each calendar year. Royalties payable under this Section 5.2 will be payable only once with respect to a particular unit of Product and will be paid only once
regardless of the number of Patents, if any, with claims covering a Product. 
 5.3 Annual Extension Fee. For each
Extension Term, Prometheus shall pay to Novartis an amount of [* * *] U.S. dollars ($[* * *]) at the time when it provides notice to Novartis of its election to extend in accordance with Section 10.1 (the “Annual Extension
Fee”). Notwithstanding the foregoing, if at any time during the Term a Significant Market Event occurs in the Territory, then commencing with the next occurring Extension Term and for all remaining Extension Terms thereafter until the first
Extension Term occurring after the SME Termination Date, Prometheus shall not be liable to pay any Annual Extension Fees in consideration for its right to extend the Term. After the SME Termination Date, Prometheus shall pay the Annual Extension Fee
for the first Extension Term occurring after the SME Termination Date and for all remaining Extension Terms thereafter, subject to the continuing applicability of this Section 5.3.

 5.4 Permitted Royalty Reductions. 
 (a) License of Third Party Intellectual Property. The Royalty during the Term may be reduced in a country in the
Territory to account for any and all royalties or other payments paid by Prometheus, its Affiliates and/or Sublicensees to any Third Party in such country, up to a maximum reduction of [* * *] percent ([* * *]%) in the aggregate of the applicable
Royalty, under (i) any license of additional intellectual property that is required and necessary in order to enable Prometheus to continue to Commercialize the Existing Product in accordance with the terms of this Agreement as such Product is
Commercialized by Novartis as of the Effective Date in the Field in such country, or (ii) as otherwise agreed upon by the Parties. Prometheus shall provide written notice to Novartis prior to obtaining any such license and this
Section 5.4(a) shall apply only to the extent Novartis fails to indemnify Prometheus for infringement of the applicable additional intellectual property pursuant to Section 7.1(h) or where Prometheus has been enjoined from Commercializing
the Products. Prometheus shall use Commercially Reasonable Efforts to minimize any such royalties or other payments to Third Parties on account of sales of Product hereunder. For the avoidance of doubt, this Section 5.4(a) shall not apply to
any Products other than the Existing Product. 
 (b) Prometheus Combination Products. The Royalty payable
by Prometheus to Novartis with respect to each Prometheus Combination Product shall be based on the Net Sales price of the Product when sold separately, such Net Sales price to be calculated based on the average Net Sales price of such Product over
the [* * *] ([* * *]) complete Calendar Quarters immediately prior to commencement by Prometheus or its Affiliates of Commercialization of any Prometheus Combination Product in the Territory. By way of example only, if Prometheus sells a Product at
a unit price of [* * *] U.S. dollars ($[* * *]), sells a second product at a unit price of [* * *] U.S. dollars ($[* * *]), and sells a Prometheus Combination Product including such Product and such second product at a unit price of [* * *] U.S.
dollars ($[* * *]), Royalties payable hereunder on such Prometheus Combination Product shall be calculated using a Product unit price of [* * *] U.S. dollars ($[* * *]). 
 (c) Significant Market Event. If at any time during the Term a Significant Market Event occurs (including, without
limitation, as a result of the marketing and/or sale of a Competitive Product) in a country in the Territory, then the actual Royalty rate payable to Novartis in such country during the continuance of such Significant Market Event in such country
shall be reduced by [* * *] percentage point (i.e., [* * *] percent ([* * *]%) shall be deducted from each tier of Royalties described above) for each [* * *] percentage point by which Prometheus’ Net Sales are reduced below [* * *]
percent ([* * *]%) of the [* * *] (the “Reduced Royalties”), up to a maximum reduction of [* * *] of the original Royalty rate. Prometheus shall continue to pay the Reduced Royalties with respect to all Net Sales of the
Products in the applicable country in the Territory until the SME Termination Date, following which Prometheus shall once again pay the Royalties for the applicable country in accordance with Section 5.2 subject to the continuing 
  
 *** Certain information on this page has been omitted and filed separately with
the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 46 

 
applicability of this Section 5.4. In the event of a Significant Market Event, Prometheus shall provide Novartis notice thereof within [* * *] ([* * *]) days after the [* * *] ([* * *]) of
the [* * *] ([* * *]) consecutive Calendar Quarters in which reduced sales triggered the Significant Market Event (as described in the definition of Significant Market Event) together with documentation in reasonable detail evidencing such
Significant Market Event; provided that if Prometheus fails to provide notice within such [* * *]-day period, such failure to notify shall not constitute a breach of this Agreement but Prometheus shall only be entitled to a
reduction in Royalties pursuant to this Section 5.4(c) for a period commencing [* * *] ([* * *]) days prior to the date on which Prometheus actually provides notice to Novartis of the occurrence of the applicable Significant Market Event.
Reduced Royalties shall then apply beginning with the Calendar Quarter immediately following such [* * *] ([* * *]) Calendar Quarter. 
 5.5 Milestone Payments. In consideration of Novartis entering into this Agreement and subject to the terms and conditions stated herein, Prometheus (or a designated Affiliate) shall make one-time milestone payments to Novartis with
respect to aggregate annual Net Sales (based on a calendar year) of the Products in the Territory deemed to be sold as a consequence of sales of Third Party Products (as determined in accordance with this Section 5.5). As of the Effective Date,
there are no Third Party Products approved for use in the Territory. If Third Party Products are sold in the Territory during the Term, the following one-time milestone payments due to Novartis (“Incremental Product Net Sales
Milestone”) shall be payable upon the first achievement of each of the following milestone events (the “Milestone Events”): 
 (a) [* * *] thousand U.S. dollars ($[* * *]) payable upon the achievement of aggregate annual Net Sales of the Products in the Territory deemed sold as a consequence of sales of Third Party Products equal
to [* * *] U.S. dollars ($[* * *]); 
 (b) [* * *] U.S. dollars ($[* * *]) payable upon the achievement of
aggregate annual Net Sales of the Products in the Territory deemed sold as a consequence of sales of Third Party Products equal to [* * *] U.S. dollars ($[* * *]); 
 (c) [* * *] U.S. dollars ($[* * *]) payable upon the achievement of aggregate annual Net Sales of the Products in the
Territory deemed sold as a consequence of sales of Third Party Products equal to [* * *] thousand U.S. dollars ($[* * *]); and 
 (d) [* * *] U.S. dollars ($[* * *]) payable upon the achievement of aggregate annual Net Sales of the Products in the Territory deemed sold as a consequence of sales of Third Party Products equal to [* *
*] U.S. dollars ($[* * *]). 
 The Parties acknowledge and agree that there is a potential for the product [* * *] to be
approved as a Third Party Product in the Territory. If [* * *] is approved as a Third Party Product in the Territory, the Parties agree that the incremental Product Net Sales achieved as a consequence of the approval and marketing of [* * *] in the
Territory, such sales to be used as a

 47 

 
measure of achievement of Milestone Events, are calculated based on the following methodology and assumptions: (i) the [* * *] plus Product dosage and administration (as per the pivotal
trial protocol) is 0.5 mg of [* * *], bid, sub-q + Interleukin-2: 16,400 IU/kg, bid, sub-q, (ii) a 69 Kg average weight per patient translates to an average dose of 1,131,600 IU of Product to be used in conjunction with [* * *], (iii) a
vial of Product contains 18,000,000 IU, and assuming a [* * *] percent ([* * *]%) wastage due to multiple draw-ups from each vial, this translates to [* * *] ([* * *]) whole doses of Product per vial, and (iv) based on the foregoing
assumptions, the ratio of [* * *] to Product is 0.5 mgs to [* * *] ([* * *]) of a vial, or [* * *] mgs of [* * *] to [* * *] vial of Product. Using this [* * *] ratio, the aggregate sales of Product will be determined by multiplying annual [* * *]
sales in milligrams by [* * *] to arrive at the total incremental vials of Product. This volume will be multiplied by the average unit vial price of the Product on a country-by-country basis weighted by the geographic split of [* * *] sales to
arrive at the incremental Net Sales of Product achieved as a consequence of the sale of [* * *]. Key data sources to be relied on for [* * *] sales will be (in priority order) direct sales information provided by [* * *]. 
 Notwithstanding the foregoing, the Parties contemplate that additional Third Party Products may also be approved for sale in the Territory
during the Term. In such event, the annual incremental Net Sales of the Products deemed sold as a consequence of sales of Third Party Products (including [* * *]) in the Territory shall be aggregated to determine when a Milestone Event is achieved;
provided that if any Third Party Product is indicated for use in conjunction with the Product in a ratio other than [* * *], then the dollar value which such Third Party Product contributes to the aggregation used to determine when a
Milestone Event is achieved shall be adjusted proportionately according to such different ratio. For each additional Third Party Product that is Commercialized in the Territory, the Parties agree to work together in good faith to find mutually
acceptable solutions (in the spirit of the methodology set forth above for [* * *]) to determine aggregate Product Net Sales deemed to be sold as a consequence of sales of such Third Party Products. 
 The Incremental Product Net Sales Milestone payments shall be paid by Prometheus, or its designated Affiliate, within thirty (30) days
after the occurrence of the applicable Milestone Event set forth above. Notwithstanding anything to the contrary in this Agreement, only one (1) milestone payment due pursuant to this Section 5.5 shall be payable in any single calendar

 5.6 Payment and Reports; Conversion. 
 (a) Payments and Reports. Within twenty-eight (28) days after the end of each Calendar Quarter during the Term,
Prometheus shall provide Novartis with a written report setting forth on a Product-by-Product and country-by-country basis the Net Sales, including number of Units Sold, during such Calendar Quarter and the calculation of the Royalty payable to
Novartis for such Net Sales pursuant to this Section 5, including all permitted reductions to or deductions from gross sales taken by Prometheus in accordance with this Agreement and the number of units sold on a Product-by-Product and
country-by-country basis. Such report shall be accompanied by a payment equal to the total Royalty due, if any, to Novartis pursuant to this Section 5. All payments shall be made to Novartis on or before the due date for each such report
following the end of the applicable Calendar Quarter in United States Dollars and by wire transfer to the designated account in accordance with the wire instructions provided by Novartis in writing to Prometheus. 
 (b) Conversion. Any Royalties on or other payments relating to transactions in a foreign currency shall be converted
into United States dollars in accordance with applicable Accounting Standards using a methodology which is consistently applied by Prometheus with respect to external reporting (including any annual, regular or periodic reports and registration
statements that Prometheus may file or be required to file with the SEC pursuant to Applicable Laws), or, if Prometheus does not report externally, then in a manner consistent with the methodology used by Prometheus to present its financials to
institutional lenders in the context of financing transactions, applicable to transactions under exchange regulations for the particular currency during the accounting period for which such royalty or other payment is due. 
 5.7 Audit Rights. Novartis shall have the right for a period of [* * *] ([* * *]) years after receiving any report or statement with
respect to royalties or milestones, to appoint an internationally-recognized independent Third Party accounting firm to audit the books and records of Prometheus, its Affiliates and its Sublicensees to verify the accuracy of the reports, statements,
books of accounts and payments made hereunder, as applicable, and Prometheus shall, and shall cause its Affiliates and its Sublicensees to keep for [* * *] ([* * *]) years from the end of the year to which the royalties or milestone pertains,
complete and accurate records of sales of each Product in sufficient detail to allow the royalties and milestones accruing to be determined accurately. Prometheus shall maintain all records in accordance with Prometheus’ Accounting Standards as
consistently applied. Such audit shall be conducted upon at least thirty (30) days advanced written notice to Prometheus and shall commence on a date reasonably acceptable to both Parties. Such audit shall only be during Prometheus’ normal
business hours. Such audit shall not be more frequent than once (1) per calendar year unless a prior audit has revealed deficiencies, in which case, an additional audit may be conducted within the same calendar year if elected by Novartis. The
auditing party shall be required to sign a confidentiality agreement for the benefit of, and in a form reasonably acceptable to, Prometheus. Prometheus shall be provided the opportunity to discuss any discrepancies of greater than five

percent (5%) found during such audit with the auditors prior to such auditor issuing its final report. In addition, the auditors shall redact any Confidential Information disclosed in the
proposed final report identified by Prometheus as confidential and, which the auditors agree is not necessary for purposes of calculating the Royalty or any milestones owed. The final report shall be shared with both of the Parties. If any audit
discloses any underpayments by Prometheus to Novartis, then unless contested by Prometheus within thirty (30) days after receipt of the necessary documentation of the amount owed, any underpayment shall be paid by Prometheus to Novartis within
thirty (30) days of it being so disclosed. If any audit discloses any overpayments by Prometheus to Novartis, then unless contested by Novartis within thirty (30) days after receipt of the necessary documentation of the amount owed,
Prometheus shall have the right to credit the amount of the overpayment against each subsequent quarterly payment due to Novartis until the overpayment has been fully applied. If the overpayment is not fully applied prior to the final quarterly
payment of Royalties due hereunder, Novartis shall promptly refund an amount equal to any such remaining overpayment. If Novartis’ audit demonstrates an underpayment of more than five percent (5%) for the payment due to Novartis during the
audited period, Prometheus shall be liable for Novartis’ reasonable cost of the audit that discovered such underpayment. Otherwise, Novartis shall bear the costs of such audits. 
 5.8 Withholding Taxes. Where required to do so by Applicable Law or order of a governmental body, a Party making payments hereunder
shall withhold Taxes required to be paid to a taxing authority in connection with any payments to the other Party hereunder, and, upon request of the Party to which the payment is due, the paying Party shall furnish the receiving Party with
satisfactory evidence of such withholding and payment. Any amounts withheld pursuant to this Section 5.8 shall be treated as having been paid by the Party making such withholding for all purposes under this Agreement. To the extent any payments
are made hereunder without withholding (at the request of the Party which was to receive such payment), and withholding is later determined to have been required, or is assessed, by any governmental entity, the Party receiving such payments shall
indemnify the other Party, including, without limitation, for any withholding Tax, interest and/or penalties thereon, and any other reasonable expenses related thereto. The Parties shall give reasonable assistance to each other in obtaining
exemption from withholding Taxes where available under Applicable Law, or recovering the same where an exemption is not available. 
 5.9 Late Payments. Any amounts due to Novartis under this Agreement or any portion thereof which are not paid when due, shall bear interest equal to Twelve Month LIBOR plus two percent (2%) as set by the British Bankers
Association as of the due date, or, if lower, the highest rate permitted under applicable law, calculated on the number of days such payment is delinquent.

 SECTION 7. 
 INDEMNIFICATION; LIMITATION OF LIABILITY; INSURANCE 
 7.1 Novartis Indemnification Obligations. Novartis will defend Prometheus, its Affiliates and Sublicensees and each of their respective officers, directors, trustees, agents and employees (collectively, “Prometheus
Indemnitees”) from and against all Claims, and indemnify and hold harmless such Prometheus Indemnitees from and against any and all losses, liabilities, obligations, awards, settlements, penalties, fines, sanctions, damages and reasonable
costs (including awards of court costs and reasonable attorneys’ fees) (collectively, “Losses”) that result from any such Claims, where and to the extent that such Claims are made or brought against any Prometheus Indemnitee by

 (b) the material breach of any obligation, covenant, warranty or representation made by Novartis under this Agreement; 
 (c) the Development or Commercialization of any Product outside the Territory and/or outside the Field by or on behalf of
Novartis and/or its Affiliates or licensees at any time prior to or following the Effective Date;

 (e) the Development of any Product in the Territory by
or on behalf of Novartis and/or its Affiliates or licensees during the Term; 
 (f) any violation of Applicable

 (g) a Novartis Indemnitee’s breach of any Upstream License
Agreement or any indemnification Claim by an Upstream Licensor that a Prometheus Indemnitee’s exercise of Prometheus’ rights or performance of Prometheus’ obligations in accordance with this Agreement constitutes a breach of any
applicable Upstream License Agreement; 
 (h) any Claim that the Commercialization of the Existing Product
infringes upon or misappropriates the Intellectual Property or proprietary rights of any Third Party (other than to the extent that such Claim relates to any Prometheus Improvements); 
 (i) any Claim arising under any MTA or any Existing Discount Agreement prior to its assignment to Prometheus pursuant to
Section 3.2(f) or Section 4.6, as applicable; or 
 (j) Taxes (or the non-payment thereof) that are the
responsibility of Novartis; 
  

 58 

 provided, however, except in each case to the extent that such Claim or Loss is attributable
to any matter for which Prometheus is obligated to indemnify a Novartis Indemnitee pursuant to Section 7.2 below or the Supply Agreement. For the avoidance of doubt, the disclosures made by Novartis pursuant to the Novartis Disclosure Schedule
shall not limit Novartis’ indemnification obligations set forth under this Section 7.1, except for Section 7.1(b). 
 7.2 Prometheus Indemnification Obligations. Prometheus will defend Novartis, its Affiliates, and the Upstream Licensors and each of their respective officers, directors, trustees, agents, employees and sublicensees (collectively,
“Novartis Indemnitees”), from and against all Claims, and indemnify and hold harmless such Novartis Indemnitees from and against any and all Losses that result from such Claims, where and to the extent that such Claims are made or
brought against any Novartis Indemnitee by or on behalf of a Third Party, and solely to the extent such Claim is based on or arises out of: 
 (a) the negligent, reckless or willful actions or omissions of Prometheus or its Affiliates in performing Prometheus’ obligations under this Agreement; 
 (b) the material breach of any obligation, covenant, warranty or representation made by Prometheus under this Agreement;

infringe upon or misappropriate the Intellectual Property or proprietary rights of any Third Party (other than to the extent that such Claim relates to the underlying Product Intellectual Property); 
 (g) Taxes (or the non-payment thereof) that are the responsibility of Prometheus; or 
 (h) any Claim arising under any MTA or any Existing Discount Agreement as of or after its assignment to Prometheus pursuant
to Section 3.2(f) or Section 4.6, as applicable; 
 provided, however, except in each case to the extent that such Claim
or Loss is attributable to any matter for which Novartis is obligated to indemnify a Prometheus Indemnitee pursuant to Section 7.1 above or the Supply Agreement. 
 7.3 Indemnity Procedures. A Person entitled to indemnification pursuant to either Section 7.1 or Section 7.2 will hereinafter be referred to as an “Indemnitee.” A Party

  

 59 

 
obligated to indemnify an Indemnitee hereunder will hereinafter be referred to as an “Indemnitor.” In the event an Indemnitee is seeking indemnification under either
Section 7.1 or Section 7.2, the Indemnitee will inform the Indemnitor of a Claim as soon as reasonably practicable after it receives notice of the Third Party Claim, it being understood and agreed that the failure by an Indemnitee to give
notice of a Third Party Claim as provided in this Section 7.3 will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that such Indemnitor is actually and materially prejudiced as a
result of such failure to give notice. The Indemnitee will permit the Indemnitor to assume direction and control of the defense of the Claim, and, at the Indemnitor’s expense, will co-operate as reasonably requested in the defense of the Claim.
The Indemnitee will have the right to retain its own counsel at its own expense; provided, that, if the Indemnitor assumes control of such defense and the Indemnitee reasonably concludes, based on advice from counsel, that the Indemnitor and
the Indemnitee have conflicting interests with respect to such Claim, the Indemnitor will be responsible for the cost of one counsel for the Indemnitee (and all other Indemnitees in connection with the same Claim or multiple Claims arising out of
the same events or circumstances). The Indemnitor may not settle such Claim, or otherwise consent to an adverse judgment in such Claim without the Indemnitee’s prior written consent, not to be unreasonably withheld or delayed; provided
that the Indemnitor shall not require such consent with respect to the settlement of any Claim where the sole relief provided is for monetary damages that are paid in full by the Indemnitor, which would not materially diminish or limit or otherwise
adversely affect the rights, activities or financial interests of the Indemnitee, and which does not result in any finding or admission of fault by the Indemnitee. 
 7.4 Defense of and Indemnification for Product Liability Claims. With respect to any Product Liability Claims resulting from the use or consumption of the Product in the Territory during the Term,
the Parties agree that: 
 (a) Each Party will indemnify and hold harmless the Novartis Indemnitees or the
Prometheus Indemnitees, as applicable, from and against [* * *] percent ([* * *]%) of (i) any and all Losses finally awarded by a court of competent jurisdiction or imposed by a Regulatory Authority against either Party, in each case that
result from any Product Liability Claim made or brought against any Novartis Indemnitee or Prometheus Indemnitee, as applicable, by or on behalf of a Third Party and (ii) all Losses resulting from any settlements entered into by a Party
pursuant to Section 7.4(d) relating to any Product Liability Claim made or brought against any Novartis Indemnitee or Prometheus Indemnitee. 
 (b) If either Party becomes aware of any Product Liability Claim, it shall inform the other Party as soon as reasonably practicable after it receives notice of such Product Liability Claim, it being
understood and agreed that the failure by either Party to give notice of a Product Liability Claim will not relieve the other Party of its obligations under this Agreement except and only to the extent that such the other Party is actually and
materially prejudiced as a result of such failure to give notice.

 (c) Novartis shall assume direction and control of the defense of any
Product Liability Claim, and Prometheus will cooperate as reasonably requested in the defense of such Product Liability Claim; provided that Novartis shall (i) use counsel reasonably acceptable to Prometheus; and provided
further that, if Prometheus reasonably concludes, based on advice from counsel, that Novartis and Prometheus have conflicting interests with respect to such Product Liability Claim, Prometheus shall have the right to obtain counsel of its
own, (ii) keep Prometheus reasonably informed as to the status of the defense, and (iii) consult with Prometheus in good faith with regard to all material litigation strategy decisions in connection with such defense, including without
limitation, joining Prometheus as a co-party. All reasonably incurred, direct Out-of-Pocket Costs incurred by either Party with respect to the defense of any Product Liability Claim shall be borne equally by the Parties. Novartis shall provide
Prometheus an invoice for [* * *] percent ([* * *]%) of such costs each Calendar Quarter during the Term, and Prometheus shall pay the amount set forth in such invoice to Novartis within sixty (60) days after receipt. 
 (d) Neither Party may settle any Product Liability Claim, or otherwise consent to an adverse judgment in any Product
Liability Claim without the other Party’s prior written consent, not to be unreasonably withheld or delayed. 
 (e) Each Calendar Quarter during the Term, Novartis shall provide Prometheus will a full accounting of all Losses incurred (if any) in connection with any Product Liability Claim for which each Party is obligated to indemnify the other
pursuant to Section 7.4(a), together with an invoice for [* * *] percent ([* * *]%) of such Losses. Unless otherwise disputed by Prometheus in good faith, Prometheus shall pay the amount set forth in such invoice to Novartis within sixty
(60) days after receipt. 
 7.5 No Punitive or Exemplary Damages. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY
UNDER ANY CIRCUMSTANCES OR ANY LEGAL OR EQUITABLE THEORY, WHETHER IN CONTRACT, STRICT LIABILITY OR OTHERWISE, FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, SUFFERED BY
THE OTHER PARTY UNDER THIS AGREEMENT. FOR THE AVOIDANCE OF DOUBT, ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT OR SPECIAL DAMAGES AWARDED TO A THIRD PARTY IN RELATION TO A CLAIM FOR WHICH A PARTY HAS AN INDEMNIFICATION OBLIGATION PURSUANT TO
SECTION 7.1 OR SECTION 7.2 OF THIS AGREEMENT, SHALL BE CONSIDERED DIRECT DAMAGES INCURRED BY THE INDEMNIFIED PARTY UNDER THIS AGREEMENT. 
 7.6 Insurance. During the Term of this Agreement, each Party shall at all times maintain insurance policies or self-insurance in such amounts and with such scope of coverage as are adequate to

proof of coverage (which may be a certificate or other evidence issued by a Party under a program of self-insurance) evidencing the requisite coverage required under this Section during the
Term of the Agreement. 
 SECTION 8. 
 INTELLECTUAL PROPERTY RIGHTS 
 8.1 Prosecution and Maintenance of
Product Patent Rights and Product Marks. 
 (a) As between the Parties, (i) Novartis shall have the
right and obligation, at its sole cost and expense, to conduct and control prosecution, maintenance, challenges against validity and unenforceability or patentability with respect to the Core Product Patent Rights and the Product Marks in the
Territory, or to use Commercially Reasonable Efforts to cause its Upstream Licensors to do the same, consistent with past practice for the Products, and (ii) Novartis shall have the initial right (but not the obligation), at its sole cost and
expense, to conduct and control prosecution, maintenance, challenges against validity and unenforceability or patentability with respect to the Secondary Product Patent Rights in the Territory existing as of the Effective Date, or to use
Commercially Reasonable Efforts to cause its Upstream Licensors to do the same, consistent with past practice for the Products. At Novartis’ request, Prometheus shall cooperate, and shall cause its Affiliates and Sublicensees to cooperate, with
and assist Novartis and its Upstream Licensors, as applicable, in connection with such activities. If Novartis creates any Improvements to the Product after the Effective Date which are patentable, the JDC shall discuss in good faith whether
Novartis shall prosecute and maintain Patents covering the Product and/or the applicable Improvement to the Products in such jurisdictions. 
 (b) Prometheus shall not use a Product Mark in breach of the Novartis Trademark Guidelines set forth on Exhibit R. Prometheus shall promptly notify Novartis of its intention to cease using or not
to initiate use of any Product Mark or Additional Product Mark, but in any event not less than [* * *] ([* * *]) days of the last use of such Product Mark or of the decision not to initiate use of such Product Mark or Additional Product Mark.

 (c) Novartis shall not abandon, and, to the extent it has rights to do so under the Upstream License
Agreements, shall not permit its Upstream Licensors to abandon, (i) any Product Patent Rights in the Territory, or (ii) subject to Prometheus complying with its obligations under subsection (b) of this Section 8.1, any of the
Product Marks in the Territory, without providing in each case reasonable prior written notice to Prometheus of such intention to abandon such Product Patent Rights or Product Marks (which notice shall, in any event and to the extent Novartis
receives such notice from its applicable Upstream Licensor, be given no later than sixty (60) days prior to the loss of any rights in such Product Patent Rights and/or Product Marks) and, only to the extent 
  
 *** Certain information on this page has been omitted and filed separately with

 62 

 
permitted by any applicable Upstream License Agreement, providing Prometheus an opportunity to assume responsibility for the prosecution and maintenance in Prometheus’ name of such Product
Patent Rights and/or Product Marks, as applicable, at Novartis’ sole cost and expense with respect to any Core Product Patent Rights or Product Marks, or at Prometheus’ sole cost and expense with respect to any Secondary Product Patent
Rights. 
 (d) If Prometheus reasonably believes that Novartis or its Upstream Licensor may fail to make any
required payments or take any action required for the preparation, filing, prosecution, defense or maintenance of any Product Patent Rights and/or Product Marks in the Territory within a reasonable time, Prometheus shall provide Novartis with
written notice of the same. If, having received such notice, and after discussion with Novartis, Novartis or the Upstream Licensor fails to take the required action at least [* * *] ([* * *]) Business Days before the deadline for taking such action
unless Novartis has notified Prometheus in writing within [* * *] ([* * *]) Business Days of receiving such notice that it will either take action or its Upstream Licensors will take action by the deadline or that it has elected not to take action
and not take action and does not permit Prometheus to take further action, Prometheus shall have the right (but with respect to Product Patent Rights licensed under the Upstream License Agreements, solely to the extent that Novartis has the right to
do so under the applicable Upstream License Agreement) to thereafter make any such required payments or take any such required action and (i) with respect to any Core Product Patent Rights, obtain reimbursement from Novartis for such payments
in the amounts set forth in paragraph (e) below; and (ii) with respect to any Secondary Product Patent Rights, make such payments and take any such required action at Prometheus’ sole cost and expense. 
 (e) In the event Prometheus elects to assume responsibility for any Core Product Patent Rights and/or Product Marks in
accordance with Section 8.1(c) or incurs any costs and expenses in accordance with Section 8.1(d), Novartis shall reimburse Prometheus, within forty-five (45) days after the date of a reasonably detailed invoice and back-up therefor
provided by Prometheus, [* * *] percent ([* * *]%) of Prometheus’ [* * *] associated with the prosecution and maintenance of any Core Product Patent Rights and/or Product Marks. 
 8.2 Co-Operation and Exchange of Information. Except to the extent restricted by any of the Upstream License Agreements, Novartis
shall (a) keep Prometheus reasonably informed as to the status of any of the Product Intellectual Property in the Territory (which obligation shall be deemed satisfied by Novartis by the provision to Prometheus of a bi-annual status report),
(b) consider in good faith the reasonable requests, suggestions and advice of Prometheus with respect to the prosecution, maintenance and defense of the Product Patent Rights and Product Marks in the Territory, (c) provide Prometheus with
copies of material reports and correspondence (both received and filed from/with) the receiving office of any PCT application, the U.S. Patent and Trademark Office and/or other equivalent intellectual property Regulatory Authorities in the Territory
to the extent that they relate to the Core Product Patent

 63 

 
Rights or Product Marks, and (d) provide Prometheus with a reasonable opportunity to comment on (and consider all such comments in good faith) any correspondence or filings with or to the
examiner of any Core Product Patent Rights. 
 8.3 Infringement or Misappropriation of Product Intellectual Property.

 (a) Notice of Infringement by Third Parties. If either Party should become aware of any Claim,
infringement or misappropriation or threatened Claim, infringement or misappropriation of the Product Intellectual Property by a Third Party or that the manufacture, use, importation or sale of the Product is infringing any Third Party Intellectual
Property in the Territory, it shall promptly notify the other Party in writing and provide any information available to that Party relating to such alleged infringement. 
 (b) Responsibility for Enforcement. 
 (i) Novartis shall have the initial right to bring or control, at its own expense, any enforcement action directed to an
alleged infringement or misappropriation of the Product Intellectual Property owned by Novartis or its Affiliates in the Territory, but shall consult with Prometheus in good faith with regard to all material litigation strategy decisions to the
extent permissible by the Upstream License Agreements, including without limitation, joining Prometheus as a co-party (e.g., if necessary in order for the party plaintiffs to have standing and/or a viable claim for lost profit damages).

 (ii) To the extent permitted by the applicable Upstream License Agreement, Novartis shall have the initial
right to bring or control, at its own expense, any enforcement action directed to an alleged infringement or misappropriation of the Upstream Licensed Patents and/or the Upstream Licensed Know-How in the Territory, but shall consult Prometheus in
good faith with regard to all material litigation strategy decisions, including without limitation, joining Prometheus as a co-party (e.g., if necessary in order for the party plaintiffs to have standing and/or a viable claim for lost profit
damages). 
 (iii) In the event that the enforcement of any Upstream Licensed Patent and/or any Upstream Licensed
Know-How is the responsibility of the applicable Upstream Licensor pursuant to Upstream License Agreements or an enforcement action cannot be brought by Novartis for lack of standing, Novartis agrees that, to the extent that Novartis has the right
to do so under the Upstream License Agreement, Novartis (i) shall use Commercially Reasonable Efforts to cause such Upstream Licensor to bring or control in accordance with the applicable Upstream License Agreement, any enforcement action
directed to an alleged infringement or misappropriation of the Upstream Licensed Patents and/or the Upstream Licensed Know-How in the Territory, (ii) shall consult Prometheus in good faith with regard to all material litigation strategy
decisions, including without limitation, whether to join Prometheus and/or Novartis as co-parties, and (iii) shall not permit such Upstream Licensor to settle (or make any stipulation during) such enforcement action in a manner that would
negatively affect

  

 64 

 
Prometheus’ rights and licenses pursuant to this Agreement without first obtaining Prometheus’ prior written consent, which consent shall not be unreasonably withheld, delayed or
conditioned. 
 (iv) In the event that Novartis or an Upstream Licensor does not file suit against or commence
settlement negotiations with the party responsible for an alleged infringement of any Product Intellectual Property within [* * *] ([* * *]) days of receipt of a written demand from Prometheus that Novartis and/or its Upstream Licensor bring suit,
and it is determined by Prometheus after good faith consultation with Novartis that a suit should be filed by Novartis and/or the applicable Upstream Licensor, but Novartis and/or the applicable Upstream Licensor does not file suit or commence
settlement negotiations forthwith against the infringer, then Prometheus shall have the right, at its own expense, to bring or control any enforcement action directed to the alleged infringement on behalf of itself, Novartis, and/or the Upstream
Licensor, to the extent permitted by the relevant Upstream License Agreement. 
 8.4 Cooperation and Joinder. 

(a) Prometheus shall reasonably cooperate in any enforcement action brought by Novartis or an Upstream Licensor pursuant
to Section 8.3(b)(i), (ii) or (iii) above. In addition, to the extent determined in accordance with such Sections that Prometheus should be joined as a party, be permitted to join or be joined as a party therein, then, to the extent
such cooperation or joinder came as a result of Novartis’ or the Upstream Licensor’s request, Novartis or the Upstream Licensor, as applicable, agrees to reimburse Prometheus for all Out-of-Pocket Costs (excluding reasonable
attorneys’ fees unless the Parties are unable to utilize the same legal counsel due to an ethical conflict), that it may incur in connection with such assistance or joinder, including any award of costs against it. 
 (b) To the extent required or permitted in accordance with the applicable Upstream License Agreements, Novartis shall
reasonably cooperate in any enforcement brought by an Upstream Licensor pursuant to Section 8.3(b)(iii), and as necessary join or be joined as a party therein. 
 (c) Novartis shall and shall cause the applicable Upstream Licensor to the extent permitted by the relevant Upstream License
Agreement to reasonably cooperate in any enforcement brought by Prometheus pursuant to Section 8.3(b)(iv), and as necessary join or be joined as a party therein, provided Prometheus agrees to reimburse Novartis and/or the Upstream Licensor, as
applicable, for all Out-of-Pocket Costs, damages and expenses, (excluding reasonable attorneys’ fees unless the Parties are unable to utilize the same legal counsel due to an ethical conflict), that it may incur in connection with such
assistance or joinder, including any award of costs against it. 
  
 *** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 65 

 (d) Any costs, expenses or damages hereunder to be reimbursed by one Party
to the other shall be paid by the owing Party within sixty (60) days of receipt of an invoice therefor, including evidence that such costs, expenses or damages have been incurred. 
 8.5 Retention of Amounts Recovered. Except as otherwise required by the terms of any applicable Upstream License Agreements, any
amount recovered in any action or suit brought in accordance with Section 8.3, whether by judgment or settlement, shall be applied as follows, unless otherwise agreed in writing by the Parties: 
 (a) First, to reimburse the Parties for their respective costs and expenses incurred in connection with such action or suit
in accordance with Sections 8.3 and 8.4; and 
 (b) Second, if 
 (i) Novartis or an Upstream Licensor brings an enforcement action, then any amounts remaining shall be allocated
[* * *] percent ([* * *]%) to Prometheus and [* * *] percent ([* * *]%) to Novartis and/or its Upstream Licensor, as applicable; or 
 (ii) Prometheus or its Affiliates or a Sublicensee brings an enforcement action, then any amounts remaining shall be allocated [* * *] percent ([* * *]%) to Prometheus and/or its Sublicensee, as
applicable, and [* * *] percent ([* * *]%) to Novartis and/or its Upstream Licensor, as applicable; 
 In the event of any
inconsistency between the terms of this Section 8.5 and the terms of any Upstream License Agreement, amounts recovered in any enforcement action or suit brought in accordance with Section 8.3 that pertain to the Upstream License Agreement
shall be paid or retained in accordance with the terms of the applicable Upstream License Agreement. 
 8.6 Improvements.

 (a) Ownership of Intellectual Property. The Parties agree that all determinations of inventorship shall
be made in accordance with United States patent laws. Subject to the licenses granted pursuant to this Agreement, each Party or its Affiliates shall retain all right, title and interest in and to all Intellectual Property developed or acquired by
such Party or its Affiliates prior to the Effective Date or during the Term which is outside the scope of this Agreement. The Parties shall jointly own all Improvements to one or more Products which are invented jointly by at least one employee or
agent of each Party or its Affiliates (each a “Joint Improvement”). Prometheus and Novartis, as joint owners, shall each have the right to practice and to grant licenses under any Patent Rights covering Joint Improvements without
the other Party’s consent or a duty of accounting, except as otherwise provided in this Agreement or agreed in writing by the Parties or as required by Applicable Law. The Parties shall

the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 66 

 
determine the responsible Party for prosecution, maintenance and enforcement of Patents covering Joint Improvements, and the allocation of costs and recoveries associated with these activities,
through mutual agreement on a case-by-case basis. Further, as between the Parties: 
 (i) Prometheus shall
exclusively own: (A) any Prometheus Confidential Information; (B) the Prometheus Improvements; and (C) any and all Regulatory Approvals filed or awarded to Prometheus or its Affiliates during the Term in any jurisdiction in the
Territory related to the Products, all subject to Section 10.7(d). 
 (ii) Novartis shall exclusively own:
(A) any Novartis Confidential Information; and (B) the Novartis Improvements. 
 (b) Licenses to
Novartis. If during the Term Prometheus or its Affiliates develops any Improvements (expressly excluding any Diagnostic Improvements) to one or more Products (each a “Prometheus Improvement”) or any Necessary (as defined below)
Diagnostic Improvements, Prometheus hereby grants to Novartis, and Novartis shall receive: 
 (i) Licenses to
Novartis Necessary for the Products. 
 (A) a [* * *] license under all Intellectual Property controlled by
Prometheus or any of its Affiliates covering the Prometheus Improvements solely for the purpose of manufacturing, Developing, using and/or Commercializing the Products in or outside the Territory after (but not during) the Term; 
 (B) a [* * *] license under all Intellectual Property controlled by Prometheus or any of its Affiliates covering any
Necessary Diagnostic Improvements solely for the purpose of manufacturing, Developing, using and/or Commercializing the Products in or outside the Territory after (but not during) the Term; provided that Prometheus shall have the right to
continue to perform all diagnostic testing covered by any Necessary Diagnostic Improvements (as applicable) on commercially reasonable terms and compensation to be agreed upon by the Parties. For the purposes hereof, “Necessary”
with respect to Prometheus Improvements or Diagnostic Improvements, shall mean that such Prometheus Improvements or Diagnostic Improvements, as the case may be, are included in the labeling for any of the Products or are required to be incorporated
into or used in conjunction with the Products by any Applicable Law or any Regulatory Authority; and 
 (C) a [*
* *] license under all Intellectual Property controlled by Prometheus or any of its Affiliates covering any and all Necessary Prometheus Improvements or Necessary Diagnostic Improvements, in each case, solely for the purpose of manufacturing,
Developing, using and/or Commercializing the Products outside the Territory at any time during the Term. 
  
 *** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 67 

 For the avoidance of doubt, to the extent the Intellectual Property covering the Prometheus
Improvements and Necessary Diagnostic Improvements licensed to Novartis pursuant to this subsection (i) have applicability to any product (an “Other Product”) outside of the Product(s) or any Generic of the Product, nothing in
this section shall be construed as preventing Prometheus from licensing such Intellectual Property to any Third Party for use with such Other Product, provided that such license does not interfere with the licenses granted to Novartis hereunder.

 (ii) Other Licenses to Novartis. 
 (A) a [* * *] license under all Intellectual Property owned or licensed (with right to further sublicense) by Prometheus or
any of its Affiliates covering such Prometheus Improvements that are not included in subsection (i) above, but which Novartis elects to receive solely in order to manufacture, Develop, use and/or Commercialize the Products outside the Territory
at any time during or after the Term or in the Territory after the Term; and 
 (B) in the event that Prometheus
or its Affiliates ceases commercializing any Diagnostic Improvement used in conjunction with the Product (and is not being licensed to Novartis pursuant to Section 8.6(b)(i) above), [* * *] license under all Intellectual Property owned or
licensed (with right to further sublicense) by Prometheus or any of its Affiliates covering such Diagnostic Improvement solely in order to manufacture, Develop, use and/or Commercialize the Products outside the Territory at any time after the Term.

 To the extent any Prometheus Improvement or any Diagnostic Improvement described above has been licensed to Prometheus or its
Affiliates from a Third Party, Prometheus shall ensure that the license(s) granted under this Section 8.6(b) shall include a sublicense under such license on the same terms and conditions (including any royalty or other payment provisions) that
such Third Party has granted such license to Prometheus or its Affiliates, as applicable. If, however, after using Commercially Reasonable Efforts in good faith, Prometheus and/or its Affiliates cannot [* * *] with respect to a Prometheus
Improvement or Diagnostic Improvement, Prometheus and/or its Affiliates shall assign such license to Novartis or its Affiliate in lieu of granting a sublicense, provided that Novartis shall have the right to refuse such assignment, in its
sole discretion, in which case it will forego rights under such license. Notwithstanding the foregoing, if Prometheus and/or its Affiliates has [* * *], Prometheus and/or its Affiliates shall have the right to assign such license to Novartis or its
Affiliate in lieu of granting a sublicense, provided that Novartis shall have the right to refuse such assignment, in its sole discretion, in which case it will forego rights under such license.

 68 

 (c) Prosecution and Maintenance. Prometheus shall have the right (but
not the obligation), at its sole cost and expense, to conduct and control prosecution, challenges against validity and unenforceability or patentability with respect to any Patents in the Territory covering Prometheus Improvements. If Prometheus or
its Affiliates create any Prometheus Improvements which are patentable, Prometheus shall promptly consult with Novartis and the Parties shall mutually agree in writing to the allocations of responsibility and control regarding the conduct of
prosecution and maintenance regarding any Patents outside of the Territory covering such Prometheus Improvements. If Prometheus intends to abandon its prosecution and maintenance of any such Patents, whether in the Territory or outside the
Territory, it shall provide reasonable prior written notice to Novartis of such intention to abandon such Patents (which notice shall be given no later than [* * *] ([* * *]) days prior to the loss of any rights in such Patents) and shall provide
Novartis or the Upstream Licensors an opportunity to assume responsibility for the prosecution and maintenance of such Patents in Novartis’ name or the Upstream Licensor’s name, as applicable. 
 (d) Enforcement. If either Party becomes aware of any actual or threatened infringement or misappropriation of any
Prometheus Improvements by a Third Party or that the practice of any Prometheus Improvements is infringing any Third Party Intellectual Property, it shall promptly notify the other Party in writing and provide any information available to it
relating to such alleged infringement. Prometheus shall have the right (but not the obligation) to bring or control, at its own expense, any enforcement action directed to an alleged infringement or misappropriation of any Prometheus Improvements,
provided that if Prometheus does not file suit against or commence and conclude settlement negotiations with the party responsible for an alleged infringement of any Prometheus Improvement within ninety (90) days of receipt of a written
demand from Novartis to bring suit and such Prometheus Improvement is licensed to Novartis pursuant to Section 8.6(b)(i), Novartis shall have the right, at its own expense, to bring or control any enforcement action directed to the alleged
infringement on behalf of itself and Prometheus. Each Party shall reasonably cooperate in any enforcement action brought by the other Party with respect to any Prometheus Improvements in accordance with this Section, and as necessary join or be
joined as a party therein, provided the other Party agrees to reimburse it for all Out-of-Pocket Costs, damages and expenses (excluding reasonable attorneys’ fees unless the Parties are unable to utilize the same legal counsel due to an ethical
conflict) that it may incur in connection with such assistance or joinder, including any award of costs against it. Any amount recovered in any action or suit brought in accordance with this Section, whether by judgment or settlement, shall be
applied (unless otherwise agreed in writing by the Parties) first, to reimburse the Parties for their respective costs and expenses (including reasonable attorneys’ fees and costs) incurred in prosecuting such infringement action, and any
remaining amounts shall be retained by the Party bringing such action.

 SECTION 9. 
 CONFIDENTIALITY 
 9.1 Nondisclosure.
Confidential Information of the other Party shall be kept strictly confidential by the receiving Party and, except as expressly permitted herein or otherwise mutually agreed to by the Parties, shall not be disclosed to any Third Party by the
receiving Party in any manner whatsoever, in whole or in part, without first obtaining the other Party’s prior written consent to such disclosure. The standard of care required of each Party in protecting the confidentiality of the other
Party’s Confidential Information shall be at least the same standard of care that the receiving Party uses in protecting its own confidential and trade secret information, but in no event shall either Party use less than a reasonable standard
of care. Except as mutually agreed upon by the Parties, Confidential Information may be used by the receiving Party or its Affiliates only for the purpose of exercising its rights and performing its obligations under this Agreement. 
 9.2 Permitted Exceptions. Each Party may disclose the other Party’s Confidential Information (i) to its employees, outside
advisors, Affiliates, and in the case of Novartis its Upstream Licensors, or in the case of Prometheus its Sublicensees who reasonably need to know such information for the purpose of advising or assisting it in connection with this Agreement or in
connection with exercising rights or performing obligations under the Upstream License Agreements or any Sublicense, as applicable, and, in addition, Prometheus may disclose the terms of this Agreement to any institutional investors or lenders of
Prometheus who reasonably need to know such information for the purposes of evaluating Prometheus’ finances (each such employee, outside advisor, Affiliate, Upstream Licensor, Sublicensee, investor or lender being referred to herein as a
“Representative”), (ii) to Regulatory Authorities in furtherance of obtaining and maintaining the Regulatory Approvals, Development of the Products or the prosecution of Product Patent Rights, and (iii) to any Third
Parties if required by Applicable Law, subject to Section 9.5. Prior to disclosing any Confidential Information to any Representative pursuant to this Section 9.2, the receiving Party will inform such Representative of the proprietary
nature of the Confidential Information and will require such Representative to agree in writing (except in the case of Affiliates or outside legal advisors or auditors, who may orally agree) to be bound by obligations of confidentiality and non-use
no less restrictive than the requirements of this Section 9. Each Party agrees to be responsible for any breach of these confidentiality obligations by its Representatives. Either Party may disclose the existence of this Agreement and the terms
and conditions hereof, without the prior written consent of the other Party, as may be required by applicable Law (including, without limitation, disclosure requirements of the Securities and Exchange Commission (“SEC”), NYSE, or
any other stock exchange or NASDAQ), in which case the Party seeking to disclose the information shall give the other Party reasonable advance notice and the right to review and comment on any such disclosure (including any proposed filing of this
Agreement with the SEC or equivalent governing body outside the U.S.) and shall seek confidential treatment of such Confidential Information to the extent possible under Applicable Law. Furthermore, notwithstanding anything to the contrary set forth
herein, Novartis and its Affiliates shall have the right to disclose the existence of this Agreement and the terms and conditions hereof to any of the Upstream Licensors, to the extent required by the applicable Upstream License Agreements.

  

 70 

 9.3 Consent. Confidential Information of the other Party shall not be utilized by a
receiving Party except as expressly permitted herein, without first obtaining the other Party’s prior written consent to such utilization. 
 9.4 Excluded Information. Notwithstanding any provision herein to the contrary, the requirements of this Section 9 shall not apply to any information of either Party which: 
 (a) at the time of disclosure hereunder is generally available to the public; 
 (b) after disclosure hereunder becomes generally available to the public, except through breach of this Section 9 by the
receiving Party or its Representatives; 
 (c) was not acquired directly or indirectly from the disclosing Party
or its Affiliates and which the receiving Party lawfully had in its possession prior to disclosure by the disclosing Party or its Affiliates; 
 (d) is independently developed by employees or agents of the receiving Party or its Affiliates without the use of the Confidential Information of the disclosing Party or its Affiliates; or 
 (e) becomes available to the receiving Party from a Third Party that is not legally prohibited from disclosing such
Confidential Information, provided such information was not acquired directly or indirectly from the disclosing Party or its Affiliates. 
 9.5 Notification of Mandatory Disclosure. 
 (a)
Procedures. In the event that either Party is required by Applicable Law or by judicial or administrative process to disclose any part of the other Party’s Confidential Information, such Party shall (i) promptly notify the other
Party of each such requirement and identify the documents so required thereby, with a view to permitting the other Party to seek an appropriate protective order or other remedy and/or waive compliance by the first Party with the provisions of this
Section 9, (ii) consult with the other Party on the advisability of taking legally available steps to resist or narrow the scope of such requirement, (iii) assist the other Party in seeking a protective order or equivalent, and
(iv) comply with any applicable protective order or equivalent. 
 (b) Limitations. If, in the
absence of such a protective order or such a waiver by the other Party of the provisions of this Section 9, the first Party is nonetheless required by Applicable Law to disclose any part of the other Party’s Confidential Information, the
first Party may disclose such of the other Party’s Confidential Information without liability under this Agreement, except that the first Party shall (i) furnish only that portion of the other Party’s Confidential Information which is
legally required and (ii) use its best efforts to obtain an order or other reliable assurances that confidential treatment will be accorded to the portion of such Confidential Information so required to be disclosed. 
  

 71 

 9.6 Publicity. All publicity, press releases and public announcements, in each case
relating to the Products (other than press releases or public announcements by Novartis or its Affiliates outside the Territory which would not reasonably be expected to have an impact on the Development or commercialization of the Product in the
Territory) and/or the transactions contemplated hereby shall be reviewed in advance by, and shall be subject to the written approval (such approval not to be unreasonably withheld) of both Parties; provided that such publicity, press releases
and other public announcements shall not disclose any Confidential Information of the other Party hereunder and shall give appropriate attribution to the other Party’s role(s) in the project contemplated herein. Notwithstanding the foregoing,
the Parties have agreed to the initial press release attached hereto as Exhibit O to be issued after January 25, 2010, and further disclosures of substantially the same information included therein. Each Party shall provide the other
Party an opportunity to review and comment on the language of such attribution prior to first use thereof in a press release or other public disclosure. Furthermore, each Party shall notify the other Party prior to the first public disclosure of any
data generated by it, its Affiliates, Sublicensees or licensees (as applicable) relating to the Products in the Territory, and shall provide the other Party an opportunity to review and comment on the language of such disclosure. Any information
that is contained in an approved disclosure as described in the preceding sentences may be disclosed subsequently by either Party without the need to seek any further approval, subject to any restrictions that apply to the original disclosure.
Notwithstanding anything to the contrary set forth herein, no publicity, press releases or public announcements, in each case relating to the Products or the terms of this Agreement or the Supply Agreement or the transactions contemplated hereby and
thereby, shall be made by either Party prior to January 25, 2010; provided, however, that each of Novartis and Prometheus shall have the right to notify or inform its Customers, suppliers, vendors and any other Persons regarding the
transactions contemplated by this Agreement and/or the Supply Agreement in order to carry out the assignments, transfers, deliveries and other obligations as contemplated by this Agreement. Furthermore, it shall not constitute a breach of this
Section 9.6 where and to the extent that (i) Novartis or its Affiliates contact any healthcare providers or institutions or any other Persons who utilize the Product or treat patients with the Product in the Field who Novartis or its
Affiliates normally call upon in the ordinary course of business in order to inform them of the transfer of Product responsibility from Novartis to Prometheus; and (ii) subject to the penultimate sentence of Section 9.2, Prometheus makes
any disclosures or submit any filings to the SEC prior to January 18, 2010 relating to the Products or the terms of this Agreement or the Supply Agreement or the transactions contemplated hereby and thereby. The Parties shall mutually agree in
writing to a public statement that either Party is permitted to make in the event a Person contacts such Party with regards to this Agreement and/or the Supply Agreement and/or the transactions contemplated hereby or thereby, during the period
commencing on the Effective Date and ending on January 24, 2010. 
 9.7 Non-Disparagement. During the Term, Novartis
agrees not to, and to cause its Affiliates, directors, officers, and senior management, not to, disseminate or publish in the context of professional or business activities any written, oral or electronically transmitted statement that is
disparaging, deleterious or damaging to the integrity, reputation or goodwill of the Products, and will inform its directors, officers and senior management of the terms of this Section. For the avoidance of doubt, the publication of any scientific
or clinical data, and any factual statements or required disclosures by Novartis or its Affiliates, directors, officers and senior management regarding such results or data shall not be considered a breach of this

  

 72 

 
Section 9.7. The Parties also agree that the promotion by Novartis or its Affiliates of any drug in compliance with Applicable Laws and the guidelines of any Regulatory Authorities shall not
in and of itself constitute a breach of this Section 9.7. 
 SECTION 10. 
 TERM AND TERMINATION 
 10.1 Term. The term of this Agreement will commence on the Effective Date and, unless sooner terminated as provided in this Section 10, shall continue until January 31, 2016 (the
“Initial Term”), following which Prometheus shall have the sole right to extend the term of this Agreement on an annual basis for up to six (6) additional one-year (1) periods, subject to early termination as provided in
this Section 10 (each an “Extension Term”) by providing notice of its election to extend not less than one hundred and twenty (120) days prior to the expiration of the Initial Term or the then-current Extension Term, as
applicable, and paying the applicable Annual Extension Fee in accordance with Section 5.3. The Initial Term together with all Extension Terms shall be referred to herein as the “Term”. 
 10.2 Termination for Material Breach. 
 (a) Each Party will be entitled to terminate this Agreement in its entirety at any time during the Term by written notice to the other Party in the event that the other Party is in material default or
breach of any material representation, warranty or obligation of such Party hereunder or under the Supply Agreement, and fails to remedy any such default or breach within the Cure Period (as defined below) after notice thereof by the
non-defaulting/non-breaching Party. If such default or breach is not corrected within the applicable Cure Period, the non-defaulting/non-breaching Party will have the right to immediately terminate this Agreement by giving written notice to the
Party in default or breach. For the avoidance of doubt, the following events shall be deemed to be a material breach of this Agreement by Prometheus: (i) the failure by Prometheus to pay any material amounts owing hereunder or under the Supply
Agreement as set forth in this Agreement or the Supply Agreement, as applicable; (ii) the failure by Prometheus to meet any Minimum Marketing Spend or Minimum Detail Requirements in accordance with this Agreement, except as otherwise expressly
permitted pursuant to Section 4.12(b); or (iii) the occurrence of a Financing Default. The “Cure Period” shall be ten (10) days in the event of a breach described in clause (i) of the preceding sentence, and, in
all other cases shall be sixty (60) days; except that there shall be no Cure Period for a Financing Default. Notwithstanding anything to the contrary set forth under this Section 10.2(a) or under this Agreement, in the event of a Financing
Default, (A) Novartis shall have the right to terminate this Agreement immediately upon the occurrence of such Financing Default and for a period of thirty (30) days thereafter, such termination being effective immediately upon
Novartis’ written notice of termination; and (B) if Novartis so terminates this Agreement, such termination shall be deemed to be effective irrespective of whether such Financing Default is subsequently cured or waived. 
 (b) In addition, Prometheus will be entitled to terminate this Agreement in its entirety at any time during the Term by
written notice to Novartis in the event of a

  

 73 

 
Novartis Catastrophic Breach, such written notice to be given no later than sixty (60) days after the occurrence of the Novartis Catastrophic Breach unless otherwise agreed to by the Parties
in writing. Failure to give such notice within such sixty (60) day period shall constitute forfeiture of Prometheus’ right to terminate this Agreement pursuant to this Section 10.2(b) as a result of such Novartis Catastrophic Breach.
Notwithstanding the forfeiture or election of Prometheus not to terminate pursuant to this Section 10.2(b), Prometheus shall retain all other rights and remedies available to it at law, in equity or provided under this Agreement. For purposes
hereof, “Novartis Catastrophic Breach” means the occurrence of any of the following: 
 (i)
Novartis’ breach of [* * *] due to a [* * *] (as defined in [* * *]) which breach both continues uncured for a period of [* * *] ([* * *]) consecutive months after the expiration of the [* * *] and results in a [* * *] for a period of more than
[* * *] ([* * *]) days. For the purposes hereof, “[* * *]” means that [* * *] shall be [* * *], which the Parties agree shall mean [* * *] of [* * *] ([* * *]) days [* * *], provided that [* * *]; 
 (ii) Novartis’ breach of any of clauses [* * *] of Section 6.2(d) (provided, that for purposes of this
Section 10.2(b)(i) only, [* * *] which: 
 (A) results in Prometheus being required to [* * *] for a period
of more than [* * *] ([* * *]) days pursuant to an injunction or order of a court of competent jurisdiction or any Regulatory Authority with jurisdiction in the United States, or 
 (B) permits the continued sale of the Products in the Territory but [* * *]; or 
 (iii) an [* * *]; 
 provided that with respect to any event contemplated by Sections 10.2(b)(ii)(B) or 10.2(b)(iii), as the case may be, a “Catastrophic Breach” shall not be deemed to have occurred unless and until the applicable breach (and
not any market event(s)) under this Section 10.2(b) causes a Significant Market Event. 
 With respect to the [* * *] ([* * *])-[* * *]
periods referred to in Sections 10.2(b)(i) and 10.2(b)(ii)(A), (x) Novartis shall be entitled to extend [* * *] ([* * *])-[* * *] periods for an additional [* * *] ([* * *]) days by written notice of such extension to Prometheus,
provided that Novartis shall be obligated to reimburse Prometheus for the cost of its Sales Representatives responsible for promoting the Products at a rate of [* * *] U.S. dollars ($[* * *]) per FTE, but not to exceed an aggregate of [* * *]
U.S. dollars ($[* * *]) for such thirty (30)-day period, and (y) Prometheus will be relieved of a pro rata portion of its Minimum Marketing and Promotion Investment obligations for the calendar year in which such 60-day period (together with
any extensions thereof) occurs (at a rate of a reduction of [* * *] for each [* * *] ([* * *]) day period).

 10.3 Bankruptcy. 
 (a) Either Prometheus or Novartis may terminate this Agreement without notice if an Insolvency Event occurs in relation to
the other Party. In any event when a Party first becomes aware of the likely occurrence of any Insolvency Event in regard to that Party, it shall promptly so notify the other Party in sufficient time to give the other Party sufficient notice to
protect its interests under this Agreement. 
 (b) Novartis may terminate this Agreement in the event Prometheus
rejects this Agreement under Section 365 of the United States Bankruptcy Code, 11 U.S.C. §§ 101 et seq. (the “Code”). 
 10.4 Termination for a Significant Market Event. Prometheus shall have the right to terminate this Agreement in its entirety by giving [* * *] ([* * *]) days prior written notice to Novartis in the
event that a Significant Market Event occurs for a continuous period of [* * *] ([* * *]) months or more. 
 10.5 Termination
for Change in Control of Prometheus. Any transaction that would, if consummated, result in a Change in Control Default Event (a “Change in Control Transaction”) shall be subject to the provisions of this Section 10.5.
Prometheus shall notify Novartis in writing of a proposed Change in Control Transaction as soon as reasonably practicable after Prometheus determines to enter into such transaction. Such notice shall identify the other party or parties to the
proposed Change in Control Transaction and shall provide Novartis with information material to the proposed transaction for the purpose of enabling, and that is reasonably sufficient for, Novartis to decide whether to exercise its rights under this
Section 10.5; provided, however, that Prometheus shall not be required to disclose any information (other than the identity of the other party or parties to the proposed Change in Control Transaction) that Prometheus is prohibited
from disclosing under the terms of a confidentiality agreement or covenant relating to such transaction. In the event that a transaction to which Prometheus is not a party occurs (or is proposed to occur) that results in (or would result in) a
Change in Control Default Event (for example, by way of a sale of Prometheus voting securities by existing stockholders without the involvement of Prometheus), Prometheus shall notify Novartis in writing of such transaction immediately after
Prometheus becomes aware of such transaction. Following the provision of notice by Prometheus of a proposed Change in Control Transaction in accordance with this Section 10.5, Novartis shall have a period of [* * *] ([* * *]) days during which
to approve or reject such proposed Change in Control Transaction by providing notice in writing of such election to Prometheus (the “Approval Period”). If Novartis approves the Change in Control Transaction within the Approval
Period, or if Novartis fails to reject the Change in Control Transaction within the Approval Period (in either case, a “Novartis CoC Waiver”), then Novartis shall be deemed to have waived its right to terminate this Agreement
pursuant to this Section 10.5 as a result of the closing of such Change in Control 
  
 *** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 75 

 
Transaction, provided that the closing takes place not more than one hundred eighty (180) days after the earlier of (i) expiration of the Approval Period or
(ii) Novartis’ notice of approval of the Change of Control Transaction. Novartis shall have the right, in its sole discretion, to elect to terminate this Agreement following the closing of a Change in Control Transaction (other than any
Change in Control Transaction with respect to which a valid Novartis CoC Waiver has been given or deemed given and remains in effect as provided above), provided that Novartis must exercise such right to terminate within [* * *] ([* * *])
days after closing of the Change in Control Transaction. Such termination of this Agreement shall be effective on the date upon which is [* * *] ([* * *]) days after Novartis’ notice of termination or such later date as the Parties may agree in
writing. 
 10.6 Termination for Convenience by Prometheus. Prometheus may terminate this Agreement for convenience and
without cause upon not less than [* * *] ([* * *]) days written notice to Novartis. 
 10.7 Effect of Termination.

 (a) Termination of Licenses. Upon termination or expiration of this Agreement for any reason, all
licenses and rights granted to Prometheus by Novartis under this Agreement, including, without limitation, under the Product Intellectual Property, will terminate, and all rights therein will revert to Novartis. The license granted to Novartis
pursuant to Section 8.6(b) with respect to the Prometheus Improvements and Diagnostic Improvements shall survive termination or expiration of this Agreement in accordance with the terms set forth therein. 
 (b) Prometheus Promotional Materials; Remaining Inventory; Disclosure of Information. Upon termination or expiration
of this Agreement for any reason: 
 (i) Prometheus shall cease using all Prometheus Promotional Materials except
to the extent necessary to sell its current stock of Products in accordance with sub-paragraph (ii) below. Following the Sell-Off Period, Prometheus shall provide to Novartis a representational sample of all Prometheus Promotional Materials and
training materials in Prometheus’ possession or Control and actively used by Prometheus as of the effective date of termination or expiration relating to the Products in the Territory. Novartis shall have the right, subject to compliance with
Applicable Law, to use the Prometheus Promotional Materials to design and prepare new Promotional Materials for use in Commercializing the Products in the Territory and may copy, modify and use such Prometheus Promotional Materials in the same or
similar manner as Novartis permitted Prometheus the use of the Novartis Promotional Materials pursuant to Section 4.3(a) of this Agreement, provided that, for the avoidance of doubt, nothing in this Section shall grant Novartis any
rights to copy, modify or otherwise use any Prometheus Trademarks, logos or names for any purposes without the prior express written consent of Prometheus.

 76 

 (ii) Except in the case of expiration of this Agreement or termination by
Novartis pursuant to Section 10.2 or 10.3 or termination by Prometheus pursuant to Section 10.6, Prometheus shall have a period of ninety (90) days from the effective date of termination (the “Sell-Off Period”) during
which to sell its remaining stock of the Products in accordance with the terms and conditions of this Agreement. After such Sell-Off Period, Prometheus shall cease all Commercialization of the Products in the Territory; provided that Novartis
shall repurchase all remaining Product from Prometheus at the Transfer Price paid by Prometheus therefor, but in no case to exceed the equivalent of [* * *] ([* * *]) [* * *] of Product based on historical sales rates over the prior calendar year.

 (iii) Prometheus shall provide to Novartis (A) copies of all material written communication with the FDA
and other Regulatory Authorities during the Term within ninety (90) days after the termination or expiration of this Agreement; (B) copies of all existing Product Marks and Product Trade Dress and (C) copies of any Product release
data, stability documentation and/or other manufacturing, stability and release testing documentation to the extent generated by or on behalf of, or made available to, Prometheus or its Affiliates. 
 (c) Return of Confidential Information. At any time following termination or expiration of this Agreement, upon the
request of the other Party, to the extent such Confidential Information is not reasonably necessary to enable a Party to perform its remaining obligations under this Agreement, the receiving Party shall promptly return to the other Party or destroy
the other Party’s Confidential Information, and shall destroy all copies thereof, together with all notes, drawings, abstracts and other information relating to the other Party’s Confidential Information prepared by the receiving Party or
any of its Representatives, regardless of the medium in which such information is stored; provided, however, that the receiving Party may maintain a single archival copy of the other Party’s Confidential Information in its files
for purposes of establishing the extent of disclosures by the other Party under this Agreement. At either Party’s written request, such Party’s Confidential Information that is otherwise required to be returned to it shall be destroyed by
the receiving Party and such destruction shall be certified in writing by an authorized officer of the receiving Party. The return and/or destruction of such Confidential Information as provided above shall not relieve the receiving Party of its
other obligations under Section 9. 
 (d) Assignment of Regulatory Approvals. Prometheus shall have
no further right to file for or obtain Regulatory Approvals for the Product after the effective date of any expiration or termination of this Agreement. As of the Regulatory Approval Reversion Date, all Regulatory Approvals shall be and hereby are
transferred and assigned to Novartis. In furtherance thereof, promptly, but in no event later than five (5) Business Days after the Regulatory Approval Reversion Date, Prometheus shall deliver to Novartis, electronically and in hard copy,
executed letters (in a form pre-approved by Novartis) addressed to all applicable Regulatory Authorities in the jurisdictions in the

Territory where Prometheus or its Affiliates has applied for, holds or has obtained Regulatory Approvals for the Products as of the effective date of expiration or termination, instructing the
applicable Regulatory Authorities to transfer of all such Regulatory Approvals from Prometheus or its Affiliates to Novartis. Prometheus shall execute, acknowledge and deliver such further instruments, and shall use Commercially Reasonable Efforts
to do all such other acts, necessary to effect the transfer of such Regulatory Approvals and all activities in connection therewith to Novartis, in each case at Novartis’ request. In the case of termination by Prometheus pursuant to
Section 10.2 or 10.3, Novartis shall reimburse Prometheus for reasonable costs incurred in connection therewith. For purposes hereof, the “Regulatory Approval Reversion Date” shall mean, as applicable: (i) the expiration
date of this Agreement, (ii) in the case of termination of this Agreement by Novartis pursuant to Section 10.2 or 10.3 or by Prometheus pursuant to Section 10.6, the date of such termination, or (iii) in the case of termination
of this Agreement for any other reason, the expiration date of the Sell-Off Period. 
 (e) Transition of
Products Following Termination or Expiration. Upon expiration or termination of this Agreement, the Parties shall reasonably cooperate in good faith to facilitate an orderly transition of responsibility for the Products back to Novartis.
Prometheus shall deliver to Novartis copies of such documents, records and information as are reasonably necessary to achieve such transition and to enable Novartis to assume complete internal responsibility for the Commercialization of the Products
in the same or similar manner as the transition services were provided by Novartis to Prometheus under the Transition Services Agreement and for reasonable compensation to be agreed upon by the Parties. Novartis shall be entitled to continue to
manufacture and sell, at its sole cost and risk, Products in packaging that bears Prometheus’ name and bearing Prometheus’ NDC until Novartis has alternative packaging available to it, which Novartis shall use best efforts to obtain as
soon as practicable and in no event later than ninety (90) days after the date of expiration or termination of this Agreement. Novartis shall indemnify Prometheus in connection with such manufacture and sale of Product bearing Prometheus’
name and/or a Prometheus NDC pursuant to Section 7.1. During the Term of this Agreement, Prometheus shall use Commercially Reasonable Efforts to procure and ensure the assignability to Novartis of all purchase orders, contracts, agreements, and
governmental programs with respect to the Products which Prometheus enters into in connection with Prometheus’ performance of its obligations under this Agreement which Novartis could be reasonably expected to assume in order to continue the
Development or to Commercialize the Product upon the expiration or earlier termination of this Agreement. Novartis, or any Person designated by Novartis, shall have the right, but not the obligation, to assume upon termination or expiration of this
Agreement any or all of such purchase orders, contracts, agreements, governmental programs and other arrangements with respect to the Products entered into by Prometheus that are still in force at the time of such expiration or termination
(“Transition Contracts”). Upon expiration or termination, Prometheus shall provide to Novartis a copy of all Transition Contracts and shall assign to Novartis, or any Person designated by Novartis, in a manner reasonably acceptable
to Novartis, each Transition Contract designated by Novartis; provided, however, that Novartis shall neither have nor assume any liability with respect to Prometheus’ obligations and liabilities arising prior to the effective date
of such assignment. In addition, if requested by Novartis and solely to the

  

 78 

 
extent permitted by Applicable Laws, Prometheus shall provide Novartis with [* * *] for the Products and Novartis and its Affiliates and Sublicensees shall be entitled to use such list and
contact information with regards to Prometheus Customers to continue the Development or to Commercialize the Products in the Territory upon the termination or expiration of this Agreement and thereafter. Notwithstanding anything contained in this
Section, Prometheus shall have no obligation to discuss, disclose or assign any Transition Contract to Novartis (and/or its designee) unless Prometheus has the right to do so and any such discussion, disclosure and/or assignment will be subject to
the terms and conditions of such Transition Contracts and Prometheus’ rights thereunder. 
 (f) [* * *]. For
the purposes hereof, “Catastrophic Breach Date” means: 
 (i) with respect to a Novartis
Catastrophic Breach covered by Section 10.2(b)(i), the [* * *] of the [* * *] ([* * *]) [* * *] grace period set forth in Section [* * *] for the applicable purchase order); 
 (ii) with respect to a Novartis Catastrophic Breach covered by Section 10.2(b)(ii)(A), the date that is the [* * *];

 (iii) with respect to a Novartis Catastrophic Breach covered by Sections 10.2(b)(ii)(B) or 10.2(b)(iii),
the [* * *]; 
 In the event this Agreement is [* * *] and the [* * *] Catastrophic Breach Date occurs within the [* * *] ([* * *]) years after
the Effective Date, then Prometheus shall be entitled to the following [* * *]: 
 (A) in the event that
Prometheus so terminates this Agreement and the applicable Catastrophic Breach Date occurs [* * *] of the Effective Date: [* * *] US dollars ($[* * *]); 
 (B) in the event that Prometheus so terminates this Agreement and the applicable Catastrophic Breach Date occurs
[* * *] of the Effective Date but prior to the second anniversary of the Effective Date: [* * *] US dollars ($[* * *]); and 
 (C) in the event that Prometheus so terminates this Agreement and the applicable Catastrophic Breach Date occurs [* * *] of the Effective Date but prior to the third anniversary of the Effective
Date: [* * *] US dollars ($[* * *]). 
 The Parties acknowledge and agree that, notwithstanding any other provision of this Agreement or the
Supply Agreement, with respect to any [* * *] pursuant to this Section 10.7(f), (w) [* * *], (x) damages resulting from the Novartis Catastrophic Event for which Prometheus has terminated the Agreement pursuant to Section 10.2(b)
[* * *], (y) [* * *]; and (z) notwithstanding any other provision of this Agreement, the payment of such amount by Novartis as set forth under this Section 10.7(f) shall serve [* * *], other than, if applicable, Novartis’
obligations to indemnify the Prometheus Indemnitees in connection with Third Party Claims pursuant to Section 7.1 and Product Liability Claims pursuant to Section 7.4.

 (g) Pricing. During (i) any notice period given by a terminating
Party pursuant to Section 10; and (ii) any transition period following the termination or expiration of this Agreement as provided under Section 10.7, Prometheus shall continue to price and discount the Products consistent with past
practice over the prior twelve (12) months. 
 (h) Accrued Rights and Obligations. Except as provided
in Section 10.7(f), expiration or termination of this Agreement will not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination, including any payment obligations, nor preclude
either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation. 
 10.8 Survival Upon Termination or Expiration. The following provisions will survive any expiration or termination of this Agreement
for the time period specified in such Sections, or if no such time period is specified, indefinitely: 
 (a)
Sections 1, 2.5(b)(ii) & (iii), 2.5(c), 5.7, 7.1-7.5, 8, 9.1-9.5, 10.7, 10.8, 10.9 and 11; and 
 (b) Section 1 for the sole purposes of interpreting the obligations and liabilities between the Parties surviving expiration or termination of this Agreement. 
 10.9 Irrevocable Power of Attorney. Prometheus hereby irrevocably appoints Novartis as its true and lawful attorney-in-fact, with
full power of substitution, to execute and deliver all such agreements, instruments, certificates and other documents, file any of the foregoing with applicable Regulatory Authorities, and take any and all other actions as are reasonably necessary
or appropriate, upon expiration or termination of this Agreement for any reason (other than termination by Prometheus pursuant to Sections 10.2, 10.3, 10.4 or 10.6) to effectuate the provisions of Section 10.7(d) and this Section 10.9,
including to submit the transfer letter set forth on Exhibit AA to the FDA. The power of attorney granted hereunder is coupled with an interest, and shall survive any Insolvency Event.

 80 

 
Dispute or agree upon a mechanism to resolve such Dispute within thirty (30) days of the first written request for dispute resolution under this Section 11.1 and provided that

 11.2 Force Majeure. Any delays in performance by any Party under this Agreement, other than with respect to Novartis’ obligation
to grant the licenses hereunder and Prometheus’ obligations to make payments hereunder, shall not be considered a breach of this Agreement if and to the extent caused by occurrences beyond the reasonable control of the Party affected, including
but not limited to acts of God, embargoes, governmental restrictions, terrorism, fire, flood, explosion, earthquake, hurricanes, storms, tornadoes, riots, wars, civil disorder, labor disturbances, acts of terrorism or compliance with any order of
any Regulatory Authority acting within color of right. The Party suffering such occurrence shall notify the other Party as soon as practicable of such inability and of the period for which such inability is expected to continue, and any time for
performance hereunder shall be extended by the actual time of delay caused by the occurrence; provided, that the Party suffering such occurrence uses Commercially Reasonable Efforts to mitigate any damages incurred by the other Party and
shall use Commercially Reasonable Efforts to resume full performance of its obligations under this Agreement as soon as reasonably practicable. 
 11.3 Standard Forms. In all communications, Novartis and Prometheus may employ their standard forms, but nothing in those forms shall be construed to modify or amend the terms and conditions of
this Agreement, and, in the case of any conflict herewith, the terms and conditions of this Agreement shall control.

 11.6 Assignment; Binding Effect. Neither this Agreement, nor any of the rights or
obligations of a Party may be directly or indirectly assigned, sold, delegated or otherwise disposed of without the prior written consent of the other Party; provided, however, that (i) Novartis may assign this Agreement to an
Affiliate or to a successor to all or substantially all of its assets relating to the Product Intellectual Property or the Product, and (ii) Prometheus may assign this Agreement to an Affiliate or to a successor to all or substantially all of
its business to which this Agreement relates, provided that (x) the total revenue derived by Prometheus from the sales of the Products by Prometheus and its Affiliates and Sublicensees in the immediately prior [* * *] ([* * *]) month
period represents no more than [* * *] percent ([* * *]%) of the aggregate revenues of such business to which this Agreement relates for the immediately prior [* * *] month period, each as determined in accordance with Prometheus’ Accounting
Standards as consistently applied and (y) in no event may Prometheus assign this Agreement to any Person who itself, or through its Affiliates or licensees, is Commercializing a Competitive Product. Notwithstanding the foregoing, with respect
to Product Intellectual Property licensed to Novartis pursuant to any Upstream License Agreement and sublicensed to Prometheus hereunder, such sublicense shall not be assignable by Prometheus to the extent such assignment is not permitted by the
applicable Upstream License Agreement. Any assignment or transfer of rights in breach of this Section 11.6 shall be null and void. 
 11.7 Amendment. Any amendment, modification or supplement of or to any provision of this Agreement, including the Exhibits hereto, shall be effective only in a writing and signed by a duly

 11.8 Severability. If and to the extent that any court of competent jurisdiction holds any provision (or any part thereof) of this Agreement to be invalid or unenforceable, such holding shall in no
way affect the validity or enforceability of the remainder of this Agreement, and the invalid or unenforceable provision shall be fully severed from this Agreement and there shall automatically be added in lieu thereof a provision as similar in
terms and intent to such severed provision as may be legal, valid and enforceable.

specific purpose for which made or given. 
 11.10 Drafting Ambiguities. Each Party to this Agreement and its counsel

integral part of this Agreement. 
 11.13 Injunctive Relief. Each of the Parties agrees that if certain material
obligations under this Agreement are not performed in accordance with their specific terms or are otherwise breached, (a) severe and irreparable damage would occur, (b) no adequate remedy at law would exist, and (c) damages would be
difficult to determine. Each of the Parties agrees that, in such case, the injured Party shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, as well as any other
relief permitted by Applicable Law, and the breaching Party shall waive any requirement that such Party post bond as a condition for obtaining any such relief.

same extent as such terms and conditions apply to Novartis. 
 11.15 Governing Law. This Agreement (including any claim
or controversy arising out of or relating to this Agreement) shall be governed by the law of the State of New Jersey without regard to conflict of law principles that would result in the application of any Applicable Law other than the laws of the
State of New Jersey. 
 11.16 Applicability of Section 365(n) of the Bankruptcy Code. In the event either Party
becomes a debtor under Title 11 of the U.S. Code, this Agreement shall be deemed to be, for purposes of Section 365(n) of Title 11, a license to “Intellectual Property” as defined therein and the other Party and its Affiliates, and
each of their successors and assigns as licensees shall have the rights and elections as specified in Section 365(n) of Title 11 of the U.S. Code. Without limiting the foregoing, upon termination of this Agreement by a trustee or executor of
either Party which has rejected this Agreement pursuant to any non-contractual rights afforded to it by applicable bankruptcy law and/or a U.S. or foreign bankruptcy court or other tribunal of competent jurisdiction, all rights and licenses herein
granted to the other Party shall nonetheless continue in full force and effect in accordance with the terms of this Agreement. 
 11.17 Consents to Assignment. Notwithstanding anything to the contrary contained in this Agreement, to the extent that the transfer or assignment by Novartis of an agreement with a Third Party (each a “Third Party
Agreement”) as set forth herein would require any Third Party authorizations, approvals, consents or waivers (collectively, the “Consent”), and such Consent shall not have been obtained prior to or as of the effective date
of assignment, then after the Effective Date, the Parties shall cooperate to obtain promptly such Consent. Pending receipt of any such Consent, the Parties shall use their Commercially Reasonable Efforts to implement an alternative arrangement to
permit Prometheus to receive substantially similar rights and for Prometheus to assume substantially similar obligations under any such Third Party Agreement as if such impediment to assignment or transfer did not exist, and Novartis shall, if

directed by Prometheus and on Prometheus’ behalf, exercise its right, if any, [* * *], except that Novartis shall not be obligated to [* * *] if Novartis agrees to bear
any costs and expenses associated with the [* * *]. 
 11.18 Further Actions. Each Party agrees to execute,
acknowledge and deliver such further instruments, and to do all such other commercially reasonable acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 
 11.19 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but
all of which together shall constitute one and the same instrument. 
 11.20 Entire Understanding. This Agreement, the
Exhibits attached hereto, the Novartis Disclosure Schedule, the Supply Agreement, the QA Agreement (as defined in the Supply Agreement), the Pharmacovigilance Agreement and any other agreement expressly identified herein, represent the entire
understanding and agreement between the Parties hereto with respect to the subject matter hereof, and supersede all prior and contemporaneous agreements and understandings between the Parties with respect to such subject matter, which are hereby
expressly terminated. In the event of any conflict between the terms of this Agreement and the terms of any Exhibit, the terms of this Agreement shall control and prevail.

 WARNINGS 
 Therapy with PROLEUKIN® (aldesleukin) should be restricted to patients with normal cardiac and pulmonary functions as defined by thallium stress testing and formal pulmonary function
testing. Extreme caution should be used in patients with a normal thallium stress test and a normal pulmonary function test who have a history of cardiac or pulmonary disease. 
 PROLEUKIN should be administered in a hospital setting under the supervision of a qualified physician experienced in the use
of anticancer agents. An intensive care facility and specialists skilled in cardiopulmonary or intensive care medicine must be available. 
 PROLEUKIN administration has been associated with capillary leak syndrome (CLS) which is characterized by a loss of vascular tone and extravasation of plasma proteins and fluid into the
extravascular space. CLS results in hypotension and reduced organ perfusion which may be severe and can result in death. CLS may be associated with cardiac arrhythmias (supraventricular and ventricular), angina, myocardial infarction, respiratory
insufficiency requiring intubation, gastrointestinal bleeding or infarction, renal insufficiency, edema, and mental status changes. 
 PROLEUKIN treatment is associated with impaired neutrophil function (reduced chemotaxis) and with an increased risk of disseminated infection, including sepsis and bacterial endocarditis. Consequently, preexisting bacterial
infections should be adequately treated prior to initiation of PROLEUKIN therapy. Patients with indwelling central lines are particularly at risk for infection with gram positive microorganisms. Antibiotic prophylaxis with oxacillin, nafcillin,
ciprofloxacin, or vancomycin has been associated with a reduced incidence of staphylococcal infections. 
 PROLEUKIN administration should be withheld in patients developing moderate to severe lethargy or somnolence; continued administration may result in coma.

 DESCRIPTION 
 PROLEUKIN® (aldesleukin), a human recombinant interleukin-2 product, is a highly purified protein with a molecular weight
of approximately 15,300 daltons. The chemical name is des-alanyl-1, serine-125 human interleukin-2. PROLEUKIN, a lymphokine, is produced by recombinant DNA technology using a genetically engineered E. coli strain containing an analog of the human
interleukin-2 gene. Genetic engineering techniques were used to modify the human IL-2 gene, and the resulting expression clone encodes a modified human interleukin-2. This recombinant form differs from native interleukin-2 in the following ways: a)
PROLEUKIN is not glycosylated because it is derived from E. coli; b) the molecule has no N-terminal alanine; the codon for this amino acid was deleted during the genetic engineering procedure; c) the molecule has serine substituted for cysteine at
amino acid position 125; this was accomplished by site specific manipulation during the genetic engineering procedure; and d) the aggregation state of PROLEUKIN is likely to be different from that of native interleukin-2. 
 The in vitro biological activities of the native nonrecombinant molecule have been reproduced with PROLEUKIN.1,2 

PROLEUKIN is supplied as a sterile, white to off-white, lyophilized cake in single-use vials intended for intravenous (IV)
administration. When reconstituted with 1.2 mL Sterile Water for Injection, USP, each mL contains 18 million IU (1.1 mg) PROLEUKIN, 50 mg mannitol, and 0.18 mg sodium dodecyl sulfate, buffered with approximately 0.17 mg monobasic and 0.89 mg
dibasic sodium phosphate to a pH of 7.5 (range 7.2 to 7.8). The manufacturing process for PROLEUKIN involves fermentation in a defined medium containing tetracycline hydrochloride. The presence of the antibiotic is not detectable in the final
product. PROLEUKIN contains no preservatives in the final product. 
 PROLEUKIN biological potency is determined
by a lymphocyte proliferation bioassay and is expressed in International Units (IU) as established by the World Health Organization 1st International Standard for Interleukin-2 (human). The relationship between potency and protein mass is as
follows: 
 18 million (18 x 106) IU PROLEUKIN = 1.1 mg protein

 CLINICAL PHARMACOLOGY 
 PROLEUKIN® (aldesleukin) has been shown to possess the biological activities of human native interleukin-2.1,2 In vitro
studies performed on human cell lines demonstrate the immunoregulatory properties of PROLEUKIN, including: a) enhancement of lymphocyte mitogenesis and stimulation of long-term growth of human interleukin-2 dependent cell lines; b) enhancement of
lymphocyte cytotoxicity; c) induction of killer cell (lymphokine-activated (LAK) and natural (NK)) activity; and d) induction of interferon-gamma production. 
 The in vivo administration of PROLEUKIN in animals and humans produces multiple immunological effects in a dose dependent manner. These effects include activation of cellular immunity with
profound lymphocytosis, eosinophilia, and thrombocytopenia, and the production of cytokines including tumor necrosis factor, IL-1 and gamma interferon.3 In vivo experiments in murine tumor models have shown inhibition of tumor growth.4 The exact
mechanism by which PROLEUKIN mediates its antitumor activity in animals and humans is unknown. 
 Pharmacokinetics 
 PROLEUKIN exists as biologically active, non-covalently bound microaggregates
with an average size of 27 recombinant interleukin-2 molecules. The solubilizing agent, sodium dodecyl sulfate, may have an effect on the kinetic properties of this product. 
 The pharmacokinetic profile of PROLEUKIN is characterized by high plasma concentrations following a short IV infusion, rapid
distribution into the extravascular space and elimination from the body by metabolism in the kidneys with little or no bioactive protein excreted in the urine. Studies of IV PROLEUKIN in sheep and humans indicate that upon completion of infusion,
approximately 30% of the administered dose is detectable in plasma. This finding is consistent with studies in rats using radiolabeled PROLEUKIN, which demonstrate a rapid (<1 min) uptake of the majority of the label into the lungs, liver,
kidney, and spleen. 
 The serum half-life (T 1/2) curves of PROLEUKIN remaining in the plasma are derived from
studies done in 52 cancer patients following a 5-minute IV infusion. These patients were shown to have a distribution and elimination T 1/2 of 13 and 85 minutes, respectively. 
 Following the initial rapid organ distribution, the primary route of clearance of circulating PROLEUKIN is the kidney. In
humans and animals, PROLEUKIN is cleared from the circulation by both glomerular filtration and peritubular extraction in the kidney.5-8 This dual mechanism for delivery of PROLEUKIN to the proximal tubule may account for the preservation of
clearance in patients with rising serum creatinine values. Greater than 80% of the amount of PROLEUKIN distributed to plasma, cleared from the circulation and presented to the kidney is metabolized to 
 E-6 
  

 E-6 

 

 
 amino acids in the cells lining the proximal convoluted tubules. In humans, the
mean clearance rate in cancer patients is 268 mL/min. 
 The relatively rapid clearance of PROLEUKIN has led to
dosage schedules characterized by frequent, short infusions. Observed serum levels are proportional to the dose of PROLEUKIN. 
 CLINICAL STUDIES 
 Safety and efficacy were studied in a series of single and multicenter,
historically controlled studies enrolling a total of 525 patients with metastatic renal cell carcinoma or melanoma. Eligible patients had an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1 and normal organ function as
determined by cardiac stress test, pulmonary function tests, and creatinine £1.5 mg/dL. Studies excluded patients with brain metastases, active infections, organ allografts and diseases requiring steroid
treatment. 
 The same treatment dose and schedule was employed in all studies demonstrating efficacy. PROLEUKIN
was given by 15 min IV infusion every 8 hours for up to 5 days (maximum of 14 doses). No treatment was given on days 6 to 14 and then dosing was repeated for up to 5 days on days 15 to 19 (maximum of 14 doses). These 2 cycles constituted 1 course of
therapy. Patients could receive a maximum of 28 doses during a course of therapy. In practice >90% of patients had doses withheld. Doses were withheld for specific toxicities (See “DOSAGE AND ADMINISTRATION” section, “Dose
Modifications” subsection and “ADVERSE REACTIONS” section). 
 Metastatic Renal Cell Cancer

 Two hundred fifty-five patients with metastatic renal cell cancer (metastatic RCC) were treated with single
agent PROLEUKIN in 7 clinical studies conducted at 21 institutions. Metastatic RCC patients received a median of 20 of 28 scheduled doses of PROLEUKIN. 
 In the renal cell cancer studies (n=255), objective response was seen in 37 (15%) patients, with 17 (7%) complete and 20 (8%) partial responders (See Table I). The 95% confidence
interval for objective response was 11% to 20%. Onset of tumor regression was observed as early as 4 weeks after completion of the first course of treatment, and in some cases, tumor regression continued for up to 12 months after the start of
treatment. Responses were observed in both lung and non-lung sites (e.g., liver, lymph node, renal bed occurrences, soft tissue). Responses were also observed in patients with individual bulky lesions and high tumor burden.

 Lack of efficacy with low dose PROLEUKIN regimens 
 Sixty-five patients with metastatic renal cell cancer were enrolled in a single center, open label, non-randomized trial that
sequentially evaluated the safety and antitumor activity of two low dose PROLEUKIN regimens. The regimens administered 18 x 106 IU PROLEUKIN as a single subcutaneous injection, daily for 5 days during week 1; PROLEUKIN was then administered at 9 x
106 IU days 1-2 and 18 x 106 IU days 3-5, weekly for an additional 3 weeks (n=40) followed by a 2 week rest or 5 weeks (n=25) followed by a 3 week rest, for a maximum of 3 or 2 treatment cycles, respectively. 
 These low dose regimens yielded substantially lower and less durable responses than those observed with the approved regimen.
Based on the level of activity, these low dose regimens are not effective. 
 Metastatic Melanoma 
 Two hundred seventy patients with metastatic melanoma were treated with single agent PROLEUKIN in 8 clinical studies
conducted at 22 institutions. Metastatic melanoma patients received a median of 18 of 28 scheduled doses of PROLEUKIN during the first course of therapy. In the metastatic melanoma studies (n=270), objective response was seen in 43
(16%) patients, with 17 (6%) complete and 26 (10%) partial responders (See Table II). The 95% confidence interval for objective response was 12% to 21%. Responses in metastatic melanoma patients were observed in both visceral and
non-visceral sites (e.g., lung, liver, lymph node, soft tissue, adrenal, subcutaneous). Responses were also observed in patients with individual bulky lesions and large cumulative tumor burden.

 INDICATIONS AND USAGE 
 PROLEUKIN® (aldesleukin) is indicated for the treatment of adults with metastatic renal cell carcinoma (metastatic RCC). 
 PROLEUKIN is indicated for the treatment of adults with metastatic melanoma. 
 Careful patient selection is mandatory prior to the administration of PROLEUKIN. See “CONTRAINDICATIONS”,
“WARNINGS” and “PRECAUTIONS” sections regarding patient screening, including recommended cardiac and pulmonary function tests and laboratory tests. 
 Evaluation of clinical studies to date reveals that patients with more favorable ECOG performance status (ECOG PS 0) at treatment initiation respond better to PROLEUKIN, with a higher
response rate and lower toxicity (See “CLINICAL PHARMACOLOGY” section, “Clinical Experience” subsection and “ADVERSE REACTIONS” section). Therefore, selection of patients for treatment should include assessment of
performance status. 
 Experience in patients with ECOG PS >1 is extremely limited. CONTRAINDICATIONS

 PROLEUKIN® (aldesleukin) is contraindicated in patients with a known history of hypersensitivity to
interleukin-2 or any component of the PROLEUKIN formulation. PROLEUKIN is contraindicated in patients with an abnormal thallium stress test or abnormal pulmonary function tests and those with organ allografts. Retreatment with PROLEUKIN is
contraindicated in patients who have experienced the following drug-related toxicities while receiving art earlier course of therapy: 
 Sustained ventricular tachycardia (35 beats) 
 Cardiac arrhythmias not controlled or unresponsive to management 
 Chest pain with ECG changes,
consistent with angina or myocardial infarction 
 Cardiac tamponade 
 Intubation for >72 hours 
 Renal failure requiring dialysis >72 hours

 Coma or toxic psychosis lasting >48 hours 
 Repetitive or difficult to control seizures 
 Bowel ischemia/perforation 
 GI bleeding requiring
surgery 
 WARNINGS 
 See boxed “WARNINGS” 
 Because of the
severe adverse events which generally accompany PROLEUKIN® (aldesleukin) therapy at the recommended dosages, thorough clinical evaluation should be performed to identify patients with significant cardiac, pulmonary, renal, hepatic, or CNS
impairment in whom PROLEUKIN is contraindicated. Patients with normal cardiovascular, pulmonary, hepatic, and CNS function may experience serious, life threatening or fatal adverse events. Adverse events are frequent, often serious, and sometimes
fatal. 
 Should adverse events, which require dose modification occur, dosage should be withheld rather than
reduced (See “DOSAGE AND ADMINISTRATION” section, “Dose Modifications” subsection). 
 PROLEUKIN has been associated with exacerbation of pre-existing or initial presentation of autoimmune disease and inflammatory disorders. Exacerbation of Crohn’s disease, scleroderma, thyroiditis, inflammatory arthritis,
diabetes mellitus, oculo-bulbar myasthenia gravis, crescentic IgA glomerulonephritis, cholecystitis, cerebral vasculitis, Stevens-Johnson syndrome and bullous pemphigoid, has been reported following treatment with IL-2. 
 All patients should have thorough evaluation and treatment of CNS metastases and have a negative scan prior to receiving
PROLEUKIN therapy. New neurologic signs, symptoms, and anatomic lesions following PROLEUKIN therapy have been reported in patients without evidence of CNS metastases. Clinical manifestations included changes in mental status, speech difficulties,
cortical blindness, limb or gait ataxia, hallucinations, agitation, obtundation, and coma. Radiological findings included multiple and, less commonly, single cortical lesions on MRI and evidence of demyelination. Neurologic signs and symptoms
associated with PROLEUKIN therapy usually improve after discontinuation of PROLEUKIN therapy; however, there are reports of permanent neurologic defects. One case of possible cerebral vasculitis, responsive to dexamethasone, has been reported. In
patients with known seizure disorders, extreme caution should be exercised as PROLEUKIN may cause seizures. 
 PRECAUTIONS 
 General 
 Patients should have normal cardiac, pulmonary, hepatic, and CNS function at the start of therapy. (See
“PRECAUTIONS” section, “Laboratory Tests” subsection). Capillary leak syndrome (CLS) begins immediately after PROLEUKIN® 
 E-10 
  

 E-10 

 

 
 (aldesleukin) treatment starts and is marked by increased capillary permeability
to protein and fluids and reduced vascular tone. In most patients, this results in a concomitant drop in mean arterial blood pressure within 2 to 12 hours after the start of treatment. With continued therapy, clinically significant hypotension
(defined as systolic blood pressure below 90 mm Hg or a 20 mm Hg drop from baseline systolic pressure) and hypoperfusion will occur. In addition, extravasation of protein and fluids into the extravascular space will lead to the formation of edema
and creation of new effusions. 
 Medical management of CLS begins with careful monitoring of the patient’s
fluid and organ perfusion status. This is achieved by frequent determination of blood pressure and pulse, and by monitoring organ function, which includes assessment of mental status and urine output. Hypovolemia is assessed by catheterization and
central pressure monitoring. 
 Flexibility in fluid and pressor management is essential for maintaining organ
perfusion and blood pressure. Consequently, extreme caution should be used in treating patients with fixed requirements for large volumes of fluid (e.g., patients with hypercalcemia). Administration of IV fluids, either colloids or crystalloids is
recommended for treatment of hypovolemia. Correction of hypovolemia may require large volumes of IV fluids but caution is required because unrestrained fluid administration may exacerbate problems associated with edema formation or effusions. With
extravascular fluid accumulation, edema is common and ascites, pleural or pericardial effusions may develop. Management of these events depends on a careful balancing of the effects of fluid shifts so that neither the consequences of hypovolemia
(e.g., impaired organ perfusion) nor the consequences of fluid accumulations (e.g., pulmonary edema) exceed the patient’s tolerance. 
 Clinical experience has shown that early administration of dopamine (1 to 5 μg/kg/min) to patients manifesting capillary leak syndrome, before the onset of hypotension, can help to
maintain organ perfusion particularly to the kidney and thus preserve urine output. Weight and urine output should be carefully monitored. If organ perfusion and blood pressure are not sustained by dopamine therapy, clinical investigators have
increased the dose of dopamine to 6 to 10 μg/kg/min or have added phenylephrine hydrochloride (1 to 5 μg/kg/min) to low dose dopamine (See “ADVERSE REACTIONS” section). Prolonged use of pressors, either in combination or as
individual agents, at relatively high doses, may be associated with cardiac rhythm disturbances. If there has been excessive weight gain or edema formation, particularly if associated with shortness of breath from pulmonary congestion, use of
diuretics, once blood pressure has normalized, has been shown to hasten recovery. NOTE: Prior to the use of any product mentioned, the physician should refer to the package insert for the respective product. 
 PROLEUKIN® (aldesleukin) treatment should be withheld for failure to maintain organ perfusion as demonstrated by altered
mental status, reduced urine output, a fall in the systolic blood pressure below 90 mm Hg or onset of cardiac arrhythmias (See “DOSAGE AND ADMINISTRATION” section, “Dose Modifications” 
 E-11 
  

 E-11 

 

 
 subsection). Recovery from CLS begins soon after cessation of PROLEUKIN therapy.
Usually, within a few hours, the blood pressure rises, organ perfusion is restored and reabsorption of extravasated fluid and protein begins. 
 Kidney and liver function are impaired during PROLEUKIN treatment. Use of concomitant nephrotoxic or hepatotoxic medications may further increase toxicity to the kidney or liver.

 Mental status changes including irritability, confusion, or depression which occur while receiving PROLEUKIN
may be indicators of bacteremia or early bacterial sepsis, hypoperfusion, occult CNS malignancy, or direct PROLEUKIN-induced CNS toxicity. Alterations in mental status due solely to PROLEUKIN therapy may progress for several days before recovery
begins. Rarely, patients have sustained permanent neurologic deficits (See “PRECAUTIONS” section “Drug Interactions” subsection). 
 Exacerbation of pre-existing autoimmune disease or initial presentation of autoimmune and inflammatory disorders has been reported following PROLEUKIN alone or in combination with
interferon (See “PRECAUTIONS” section “Drug Interactions” subsection and “ADVERSE REACTIONS” section). Hypothyroidism, sometimes preceded by hyperthyroidism, has been reported following PROLEUKIN treatment. Some of
these patients required thyroid replacement therapy. Changes in thyroid function may be a manifestation of autoimmunity. Onset of symptomatic hyperglycemia and/or diabetes mellitus has been reported during PROLEUKIN therapy. 
 PROLEUKIN enhancement of cellular immune function may increase the risk of allograft rejection in transplant patients.

 Laboratory Tests 
 The following clinical evaluations are recommended for all patients, prior to beginning treatment and then daily during drug administration. 
 Standard hematologic tests-including CBC, differential and platelet counts 
 Blood chemistries-including electrolytes, renal and hepatic function tests 
 Chest x-rays 
 Serum creatinine should be £1.5 mg/dL prior to initiation of PROLEUKIN treatment. 
 All patients should have baseline pulmonary function tests with arterial blood gases. Adequate pulmonary function should be
documented (FEV1 >2 liters or 375% of predicted for height and age) prior to initiating therapy. 
 All patients should be screened with a stress thallium study. Normal ejection fraction and unimpaired wall motion should be documented. If a thallium stress test suggests minor wall motion
abnormalities further testing is suggested to exclude significant coronary artery disease. 
 E-12 
  

 E-12 

 

 
 Daily monitoring during therapy with PROLEUKIN should include vital signs
(temperature, pulse, blood pressure, and respiration rate), weight, and fluid intake and output. In a patient with a decreased systolic blood pressure, especially less than 90 mm Hg, constant cardiac rhythm monitoring should be conducted. If an
abnormal complex or rhythm is seen, an ECG should be performed. Vital signs in these hypotensive patients should be taken hourly. 
 During treatment, pulmonary function should be monitored on a regular basis by clinical examination, assessment of vital signs and pulse oximetry. Patients with dyspnea or clinical signs of respiratory impairment (tachypnea
or rales) should be further assessed with arterial blood gas determination. These tests are to be repeated as often as clinically indicated. 
 Cardiac function should be assessed daily by clinical examination and assessment of vital signs. Patients with signs or symptoms of chest pain, murmurs, gallops, irregular rhythm or
palpitations should be further assessed with an ECG examination and cardiac enzyme evaluation. Evidence of myocardial injury, including findings compatible with myocardial infarction or myocarditis, has been reported. Ventricular hypokinesia due to
myocarditis may be persistent for several months. If there is evidence of cardiac ischemia or congestive heart failure, PROLEUKIN therapy should be held, and a repeat thallium study should be done. 
 Drug Interactions 
 PROLEUKIN may affect central nervous function. Therefore, interactions could occur following concomitant administration of psychotropic drugs (e.g., narcotics, analgesics, antiemetics,
sedatives, tranquilizers). 
 Concurrent administration of drugs possessing nephrotoxic (e.g., aminoglycosides,
indomethacin), myelotoxic (e.g., cytotoxic chemotherapy), cardiotoxic (e.g., doxorubicin) or hepatotoxic (e.g., methotrexate, asparaginase) effects with PROLEUKIN may increase toxicity in these organ systems. The safety and efficacy of PROLEUKIN in
combination with any antineoplastic agents have not been established. 
 In addition, reduced kidney and liver
function secondary to PROLEUKIN treatment may delay elimination of concomitant medications and increase the risk of adverse events from those drugs. 
 Hypersensitivity reactions have been reported in patients receiving combination regimens containing sequential high dose PROLEUKIN and antineoplastic agents, specifically, dacarbazine,
cis-platinum, tamoxifen and interferon-alfa. These reactions consisted of erythema, pruritus, and hypotension and occurred within hours of administration of chemotherapy. These events required medical intervention in some patients. 
 Myocardial injury, including myocardial infarction, myocarditis, ventricular hypokinesia, and severe rhabdomyolysis appear to
be increased in patients receiving PROLEUKIN and interferon-alfa concurrently. 
 E-13 
  

 E-13 

 

 
 Exacerbation or the initial presentation of a number of autoimmune and
inflammatory disorders has been observed following concurrent use of interferon-alfa and PROLEUKIN, including crescentic IgA glomerulonephritis, oculo-bulbar myasthenia gravis, inflammatory arthritis, thyroiditis, bullous pemphigoid, and
Stevens-Johnson syndrome. 
 Although glucocorticoids have been shown to reduce PROLEUKIN-induced side effects
including fever, renal insufficiency, hyperbilirubinemia, confusion, and dyspnea, concomitant administration of these agents with PROLEUKIN may reduce the antitumor effectiveness of PROLEUKIN and thus should be avoided.12 
 Beta-blockers and other antihypertensives may potentiate the hypotension seen with PROLEUKIN. 
 Delayed Adverse Reactions to lodinated Contrast Media 
 A review of the literature revealed that 12.6% (range 11-28%) of 501 patients treated with various interleukin-2 containing
regimens who were subsequently administered radiographic iodinated contrast media experienced acute, atypical adverse reactions. The onset of symptoms usually occurred within hours (most commonly 1 to 4 hours) following the administration of
contrast media. These reactions include fever, chills, nausea, vomiting, pruritus, rash, diarrhea, hypotension, edema, and oliguria. Some clinicians have noted that these reactions resemble the immediate side effects caused by interleukin-2
administration, however the cause of contrast reactions after interleukin-2 therapy is unknown. Most events were reported to occur when contrast media was given within 4 weeks after the last dose of interleukin-2. These events were also reported to
occur when contrast media was given several months after interleukin-2 treatment.13 
 Carcinogenesis,
Mutagenesis, Impairment of Fertility 
 There have been no studies conducted assessing the carcinogenic or
mutagenic potential of PROLEUKIN. 
 There have been no studies conducted assessing the effect of PROLEUKIN on
fertility. It is recommended that this drug not be administered to fertile persons of either gender not practicing effective contraception. 
 Pregnancy 
 Pregnancy Category C. 
 PROLEUKIN has been shown to have embryolethal effects in rats when given in doses at 27 to 36 times the human dose (scaled by
body weight). Significant maternal toxicities were observed in pregnant rats administered PROLEUKIN by IV injection at doses 2.1 to 36 times higher than the human dose during critical period of organogenesis. No evidence of teratogenicity was
observed other than that attributed to maternal toxicity. There are no adequate well-controlled studies of

 PROLEUKIN in pregnant women. PROLEUKIN should be used during pregnancy only if
the potential benefit justifies the potential risk to the fetus. 
 Nursing Mothers 
 It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the
potential for serious adverse reactions in nursing infants from PROLEUKIN, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. 
 Pediatric Use 
 Safety and effectiveness in children under 18 years of age have not been established. 
 Geriatric Use 
 There were a small number of
patients aged 65 and over in clinical trials of PROLEUKIN; experience is limited to 27 patients, eight with metastatic melanoma and nineteen with metastatic renal cell carcinoma. The response rates were similar in patients 65 years and over as
compared to those less than 65 years of age. The median number of courses and the median number of doses per course were similar between older and younger patients. 
 PROLEUKIN is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. The pattern of organ
system toxicity and the proportion of patients with severe toxicities by organ system were generally similar in patients 65 and older and younger patients. There was a trend, however, towards an increased incidence of severe urogenital toxicities
and dyspnea in the older patients. 
 ADVERSE REACTIONS 
 The rate of drug-related deaths in the 255 metastatic RCC patients who received single-agent PROLEUKIN® (aldesleukin) was
4% (11/255); the rate of drug-related deaths in the 270 metastatic melanoma patients who received single-agent PROLEUKIN was 2% (6/270). 
 The following data on common adverse events (reported in greater than 10% of patients, any grade), presented by body system, decreasing frequency and by preferred term (COSTART) are based
on 525 patients (255 with renal cell cancer and 270 with metastatic melanoma) treated with the recommended infusion dosing regimen.

 a Cardiovascular disorder: fluctuations in blood pressure. 
 b Coagulation disorder: intravascular coagulopathy. 
 c Respiratory disorder: ARDS, respiratory failure, intubation. 
 The following life-threatening (grade 4) events were reported by <1% of the 525 patients: hypothermia; shock; bradycardia;
ventricular extra systoles; myocardial ischemia; syncope; hemorrhage; atrial arrhythmia; phlebitis; AV block second degree; endocarditis; pericardial effusion; peripheral gangrene; thrombosis; coronary artery disorder; stomatitis; nausea and
vomiting; liver function tests abnormal; gastrointestinal hemorrhage; hematemesis; bloody diarrhea; gastrointestinal disorder; intestinal perforation; pancreatitis; anemia; leukopenia; leukocytosis; hypocalcemia; alkaline phosphatase increase; BUN
increase; hyperuricemia; NPN increase; respiratory acidosis; somnolence; agitation; neuropathy; paranoid reaction; convulsion; grand mal convulsion; delirium; asthma, lung edema; hyperventilation; hypoxia; hemoptysis; hypoventilation; pneumothorax;
mydriasis; pupillary disorder; kidney function abnormal; kidney failure; acute tubular necrosis. 
 In an
additional population of greater than 1,800 patients treated with PROLEUKIN-based regimens using a variety of doses and schedules (e.g., subcutaneous, continuous infusion, administration with LAK cells) the following serious adverse events were
reported: duodenal ulceration; bowel necrosis; myocarditis; supraventricular tachycardia; permanent or transient blindness secondary to optic neuritis; transient ischemic attacks; meningitis; cerebral edema; pericarditis; allergic interstitial
nephritis; tracheo-esophageal fistula. 
 E-17

 In the same clinical population, the following fatal events each occurred with a
frequency of <1%: malignant hyperthermia; cardiac arrest; myocardial infarction; pulmonary emboli; stroke; intestinal perforation; liver or renal failure; severe depression leading to suicide; pulmonary edema; respiratory arrest; respiratory
failure. In patients with both metastatic RCC and metastatic melanoma, those with ECOG PS of 1 or higher had a higher treatment-related mortality and serious adverse events. 
 Most adverse reactions are self-limiting and, usually, but not invariably, reverse or improve within 2 or 3 days of
discontinuation of therapy. Examples of adverse reactions with permanent sequelae include: myocardial infarction, bowel perforation/infarction, and gangrene. 
 Immunogenicity 
 Fifty-seven of 77 (74%) metastatic
renal cell carcinoma patients treated with an every 8-hour PROLEUKIN regimen and 33 of 50 (66%) metastatic melanoma patients treated with a variety of IV regimens developed low titers of non-neutralizing anti-PROLEUKIN antibodies. Neutralizing
antibodies were not detected in this group of patients, but have been detected in 1/106 (<1%) patients treated with IV PROLEUKIN using a wide variety of schedules and doses. The clinical significance of anti-PROLEUKIN antibodies is unknown.

 Post Marketing Experience 
 The following adverse reactions have been identified during post-approval use of PROLEUKIN. Because these reactions are reported voluntarily from a population of uncertain size, it Is not
always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. 
 Anaphylaxis; cellulitis; injection site necrosis; retroperitoneal hemorrhage; cardiomyopathy; cerebral hemorrhage; fatal endocarditis ; hypertension; cholecystitis; colitis; gastritis; hepatitis; hepatosplenomegaly; intestinal
obstruction; hyperthyroidism; neutropenia; myopathy; myositis; rhabdomyolysis; cerebral lesions; encephalopathy; extrapyramidal syndrome; insomnia; neuralgia; neuritis; neuropathy (demyelination); urticaria; pneumonia (bacterial, fungal, viral).

 Exacerbation or initial presentation of a number of autoimmune and inflammatory disorders have been reported
(See “WARNINGS” section, “PRECAUTIONS” section, “Drug Interactions” subsection). Persistent but nonprogressive vitiligo has been observed in malignant melanoma patients treated with interleukin-2. Synergistic, additive
and novel toxicities have been reported with PROLEUKIN used in combination with other drugs. Novel toxicities include delayed adverse reactions to iodinated contrast media and hypersensitivity reactions to antineoplastic agents (See
“PRECAUTIONS” section, “Drug Interactions” subsection). 
 Experience has shown the following
concomitant medications to be useful in the management of patients on PROLEUKIN therapy: a) standard antipyretic therapy, 
 E-18 
  

 E-18 

 

 
 including nonsteroidal anti-inflammatories (NSAIDs), started immediately prior to
PROLEUKIN to reduce fever. Renal function should be monitored as some NSAIDs may cause synergistic nephrotoxicity; b) meperidine used to control the rigors associated with fever; c) H2 antagonists given for prophylaxis of gastrointestinal irritation
and bleeding; d) antiemetics and antidiarrheals used as needed to treat other gastrointestinal side effects. Generally these medications were discontinued 12 hours after the last dose of PROLEUKIN. 
 Patients with indwelling central lines have a higher risk of infection with gram positive organisms.9-11 A reduced incidence
of staphylococcal infections in PROLEUKIN studies has been associated with the use of antibiotic prophylaxis which includes the use of oxacillin, nafcillin, ciprofloxacin, or vancomycin. Hydroxyzine or diphenhydramine has been used to control
symptoms from pruritic rashes and continued until resolution of pruritus. Topical creams and ointments should be applied as needed for skin manifestations. Preparations containing a steroid (e.g., hydrocortisone) should be avoided. NOTE: Prior to
the use of any product mentioned, the physician should refer to the package insert for the respective product. 
 OVERDOSAGE 
 Side effects following the use of PROLEUKIN® (aldesleukin) appear to be
dose-related. Exceeding the recommended dose has been associated with a more rapid onset of expected dose-limiting toxicities. Symptoms which persist after cessation of PROLEUKIN should be monitored and treated supportively. Life-threatening
toxicities may be ameliorated by the intravenous administration of dexamethasone, which may also result in loss of the therapeutic effects of PROLEUKIN.12 NOTE: Prior to the use of dexamethasone, the physician should refer to the package insert for
this product. 
 DOSAGE AND ADMINISTRATION 
 The recommended PROLEUKIN® (aldesleukin) treatment regimen is administered by a 15-minute IV infusion every 8 hours.
Before initiating treatment, carefully review the “INDICATIONS AND USAGE”, “CONTRAINDICATIONS”, “WARNINGS”, “PRECAUTIONS”, and “ADVERSE REACTIONS” sections, particularly regarding patient selection,
possible serious adverse events, patient monitoring and withholding dosage. The following schedule has been used to treat adult patients with metastatic renal cell carcinoma (metastatic RCC) or metastatic melanoma. Each course of treatment consists
of two 5-day treatment cycles separated by a rest period. 
 600,000 lU/kg (0.037 mg/kg) dose administered every
8 hours by a 15-minute IV infusion for a maximum of 14 doses. Following 9 days of rest, the schedule is repeated for another 14 doses, for a maximum of 28 doses per course, as tolerated. During clinical trials, doses were frequently withheld for
toxicity (See “Clinical Experience” and “Dose Modifications” subsections). Metastatic RCC patients treated with this 
 E-19 
  

 E-19 

 

 
 schedule received a median of 20 of the 28 doses during the first course of
therapy. Metastatic melanoma patients received a median of 18 doses during the first course of therapy. 
 Retreatment 
 Patients should be evaluated for response approximately 4 weeks after completion
of a course of therapy and again immediately prior to the scheduled start of the next treatment course. Additional courses of treatment should be given to patients only if there is some tumor shrinkage following the last course and retreatment is
not contraindicated (See “CONTRAINDICATIONS” section). Each treatment course should be separated by a rest period of at least 7 weeks from the date of hospital discharge. 
 Dose Modifications 
 Dose modification for toxicity should be accomplished by withholding or interrupting a dose rather than reducing the dose to be given. Decisions to stop, hold, or restart PROLEUKIN therapy
must be made after a global assessment of the patient. With this in mind, the following guidelines should be used: 
 Retreatment with PROLEUKIN is contraindicated in patients who have experienced the following toxicities:

 Reconstitution and Dilution Directions: Reconstitution and dilution procedures other than those recommended may alter the
delivery and/or pharmacology of PROLEUKIN and thus should be avoided. 
 1. PROLEUKIN® (aldesleukin) is a
sterile, white to off-white, preservative-free, lyophilized powder suitable for IV infusion upon reconstitution and dilution. EACH VIAL CONTAINS 22 MILLION IU (1.3 MG) OF PROLEUKIN AND SHOULD BE RECONSTITUTED ASEPTICALLY WITH 1.2 ML OF STERILE WATER
FOR INJECTION, USP. WHEN RECONSTITUTED AS DIRECTED, EACH ML CONTAINS 18 MILLION IU (1.1 MG) OF PROLEUKIN. The resulting solution should be a clear, colorless to slightly yellow liquid. The vial is for single-use only and any unused portion should be
discarded. 
 2. During reconstitution, the Sterile Water for Injection, USP should be directed at the side of
the vial and the contents gently swirled to avoid excess foaming. DO NOT SHAKE. 
 3. The dose of PROLEUKIN,
reconstituted with Sterile Water for Injection, USP (without preservative) should be diluted aseptically in 50 mL of 5% Dextrose Injection, USP (D5W) and infused over a 15-minute period. 
 In cases where the total dose of PROLEUKIN is 1.5 mg or less (e.g., a patient with a body weight of less than 40 kilograms),
the dose of PROLEUKIN should 
 E-21 
  

 E-21 

 

 
 be diluted in a smaller volume of D5W. Concentrations of PROLEUKIN below 30
μg/mL and above 70 μg/mL have shown increased variability in drug delivery. Dilution and delivery of PROLEUKIN outside of this concentration range should be avoided. 
 4. Glass bottles and plastic (polyvinyl chloride) bags have been used in clinical trials with comparable results. It is
recommended that plastic bags be used as the dilution container since experimental studies suggest that use of plastic containers results in more consistent drug delivery. In-line filters should not be used when administering PROLEUKIN. 

5. Before and after reconstitution and dilution, store in a refrigerator at 2° to 8°C (36° to 46°F). Do
not freeze. Administer PROLEUKIN within 48 hours of reconstitution. The solution should be brought to room temperature prior to infusion in the patient. 
 6. Reconstitution or dilution with Bacteriostatic Water for Injection, USP, or 0.9% Sodium Chloride Injection, USP should be avoided because of increased aggregation. PROLEUKIN should not
be coadministered with other drugs in the same container. 
 7. Parenteral drug products should be inspected
visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

 NOVARTIS 
 PROLEUKIN* (aldesleukin) 
 Interleukin-2 22 million IU/vial 
 Pharmaceutical Standard: Biologic Response Modifier 
 ACTIONS, CLINICAL PHARMACOLOGY 

PROLEUKIN* (aldesleukin) an analogue of human interleukin-2 produced by recombinant DNA technology, has been shown to
possess the biological activities of human native interleukin-2. PROLEUKIN exhibits antitumor activity; the exact mechanism by which PROLEUKIN mediates its antitumor activity in animals and humans is unknown. 
 In vitro studies performed on human cell lines demonstrate the immunoregulatory properties of PROLEUKIN, including: a)
enhancement of lymphocyte mitogenesis and stimulation of long-term growth of human interleukin-2 dependent cell lines; b) enhancement of lymphocyte cytotoxicity; c) induction of killer cell (lymphokine-activated (LAK) and natural (NK)) activity; and
d) induction of interferon-gamma production. 
 The in vivo administration of PROLEUKIN in animals and humans
produces multiple immunological effects in a dose dependent manner. These effects include activation of cellular immunity with profound lymphocytosis, eosinophilia, and thrombocytopenia, and the production of cytokines including tumor necrosis
factor, IL-1 and gamma interferon. In vivo experiments in murine tumor models have shown inhibition of tumor growth. Pharmacokinetics: PROLEUKIN exists as biologically active, non-covalently bound microaggregates with an average size of 27
recombinant interleukin-2 molecules. The solubilizing agent, sodium dodecyl sulfate, may have an effect on the kinetic properties of this product. The pharmacokinetic profile of PROLEUKIN is characterized by high plasma concentrations following a
short intravenous (IV) infusion, rapid distribution into the extravascular space and elimination from the body by metabolism in the kidneys with little or no bioactive protein excreted in the urine. 
 Studies of IV PROLEUKIN in sheep and humans indicated that upon completion of infusion approximately 30% of the administered
dose is detectable in plasma. This finding is consistent with studies in rats using radiolabeled PROLEUKIN, which demonstrate a rapid (<1 minute) uptake of the majority of the label into the lungs, liver, kidney, and spleen. 
 The serum half-life (T1/2) curves of PROLEUKIN remaining in the plasma are derived from studies done in 52 cancer patients
following a 5-minute IV infusion. These patients were shown to have a distribution and elimination T1/2 of 13 and 85 minutes, respectively. 
 The relatively rapid clearance rate of PROLEUKIN has led to dosage schedules characterized by frequent, short infusions. Observed serum levels are proportional to the dose of PROLEUKIN.

 Following the initial rapid organ distribution, the primary route of clearance of circulating PROLEUKIN is the
kidney. In humans and animals, PROLEUKIN is cleared from the circulation by both glomerular filtration and peritubular extraction in the kidney. This dual mechanism for delivery of PROLEUKIN to the proximal tubule may account for the preservation of
clearance in patients with rising serum creatinine values. Greater than 80% of the amount of PROLEUKIN distributed to plasma, cleared from the circulation and presented to the kidney is metabolized to amino acids in the cells lining the proximal
convoluted tubules. In humans, the mean clearance rate in cancer patients is 268 mL/min. 
 INDICATIONS AND
CLINICAL USE 
 PROLEUKIN* (aldesleukin) is indicated for the treatment of adults (318 years of age) with metastatic renal cell carcinoma (metastatic RCC). PROLEUKIN is indicated for the treatment of adults (318 years of age) with metastatic
malignant melanoma. 
 In the renal cell cancer studies (n=255), objective response was seen in 37
(15%) patients, with 17 (7%) complete and 20 (8%) partial responders. In the metastatic malignant melanoma studies (n=270), objective response was seen in 43 (16%) patients, with 17 (6%) complete and 26 (10%) partial
responders. Prior to enrollment into the studies, patients had progression of disease after prior therapies. A majority (96%) of patients had previous surgical resection of their primary lesions, lymph node dissections, or area of relapse.

 Careful patient selection is mandatory prior to the administration of PROLEUKIN. See
“CONTRAINDICATIONS,” “WARNINGS,” and “PRECAUTIONS” sections regarding patient screening, including recommended cardiac and pulmonary function tests and laboratory tests. 
 Evaluation of clinical studies to date reveals that patients with more favorable ECOG performance status (ECOG PS 0) at
treatment initiation respond better to PROLEUKIN, with a higher response rate and lower toxicity (see “ADVERSE REACTION” section). Therefore, selection of patients for treatment should include assessment of performance status. Experience
in patients with ECOG PS >1 is limited.

 CONTRAINDICATIONS

 PROLEUKIN* (aldesleukin) is contraindicated in patients with a known history of hypersensitivity to
interleukin-2 or any component of the PROLEUKIN formulation. 
 PROLEUKIN is contraindicated in patients with an
abnormal thallium stress test or abnormal pulmonary function tests and those with organ allo-grafts. Retreatment with PROLEUKIN is contraindicated in patients who experienced the following drug related toxicities while receiving an earlier course of
therapy: 
 Sustained ventricular tachycardia (35 beats) 

Cardiac arrhythmias not controlled or unresponsive to management 
 Chest pain with electrocardiogram (ECG) changes, consistent with angina or myocardial infarction 
 Cardiac tamponade 
 Intubation required >72 hours 
 Renal failure
requiring dialysis >72 hours 
 Coma or toxic psychosis lasting >48 hours 
 Repetitive or difficult to control seizures 
 Bowel ischemia/perforation 
 GI bleeding requiring
surgery 
 WARNINGS 
 PROLEUKIN* (aldesleukin) should be administered only to well informed patients in a hospital setting under the supervision of a qualified physician experienced in the use of anti-cancer
agents. An intensive care facility and specialists skilled in cardiopulmonary or intensive care medicine must be available. 
 PROLEUKIN administration has been associated with capillary leak syndrome (CLS) which is characterized by a loss of vascular tone and extravasation of plasma proteins and fluid into the extravascular space. CLS results in hypotension
and reduced organ perfusion, which may be severe and can result in death. CLS may be associated with cardiac arrhythmias (supraventricular and ventricular), angina, myocardial infarction, respiratory insufficiency requiring intubation,
gastrointestinal bleeding or infarction, renal insufficiency, edema and mental status changes. Because of the severe adverse events which generally accompany PROLEUKIN therapy at the recommended dosages, thorough clinical evaluation should be
performed to identify patients with significant cardiac, pulmonary, renal, hepatic, or central nervous system (CNS) impairment; PROLEUKIN is contraindicated in these patients. 
 Therapy with PROLEUKIN should be restricted to patients with normal cardiac and pulmonary functions as defined by thallium
stress testing and formal pulmonary function testing. Extreme caution should be used in patients with normal thallium stress tests and pulmonary function tests who have a history of prior cardiac or pulmonary disease. 
 Patients with normal cardiovascular, pulmonary, hepatic, and CNS function may experience serious, life threatening or fatal
adverse events. Adverse events are frequent, often serious, and sometimes fatal. 
 Should adverse events, which
require dose modification occur, dosage should be withheld rather than reduced (see “DOSAGE AND ADMINISTRATION” section, “Dose Modifications” subsection). 
 PROLEUKIN has been associated with exacerbation of pre-existing or initial presentation of autoimmune disease and
inflammatory disorders. Exacerbation of Crohn’s disease, scleroderma, thyroiditis, inflammatory arthritis, diabetes mellitus, oculo-bulbar myasthenia gravis, crescentic IgA glomerulonephritis, cholecystitis, cerebral vasculitis, Stevens-Johnson
syndrome and bullous pemphigoid, has been reported following treatment with IL-2. 
 All patients should have
thorough evaluation and treatment of CNS metastases and have a negative scan prior to receiving PROLEUKIN therapy. New neurologic signs, symptoms, and anatomic lesions following PROLEUKIN therapy have been reported in patients without evidence of
CNS metastases. Clinical manifestations included changes in mental status, speech difficulties, cortical blindness, limb or gait ataxia, hallucinations, agitation, obtundation, and coma. Radiological findings included multiple and, less commonly,
single cortical lesions on MRI and evidence of demyelination. Neurologic signs and symptoms associated with PROLEUKIN therapy usually improve after discontinuation of PROLEUKIN therapy; however, there are reports of permanent neurologic defects. One
case of possible cerebral vasculitis, responsive to dexamethasone, has been reported. In patients with known seizure disorders, extreme caution should be exercised as PROLEUKIN may cause seizures. 
 PROLEUKIN administration should be held in patients developing moderate to severe lethargy or somnolence; continued
administration may result in coma. 
 PROLEUKIN treatment is associated with impaired neutrophil function
(reduced chemotaxis) and with an increased risk of disseminated infection, including sepsis and bacterial endocarditis. Consequently, pre-existing bacterial infections should be adequately treated prior to initiation of PROLEUKIN therapy. Patients
with indwelling central lines are particularly at risk for infection with gram positive microorganisms. Antibiotic prophylaxis with oxacillin, nafcillin, ciprofloxacin, or vancomycin has been associated with a reduced incidence of staphylococcal
infections. Disseminated infections acquired in the course of PROLEUKIN treatment are a major contributor to treatment morbidity and use of antibiotic prophylaxis and aggressive treatment of suspected and documented infections may reduce the
morbidity of PROLEUKIN treatment. NOTE: Prior to the use of any product mentioned in this paragraph, the physician should refer to the Product Monograph for the respective product. PRECAUTIONS 
 General: Patients should have normal cardiac, pulmonary, hepatic, and CNS function at the start of therapy. Metastatic renal
cell carcinoma patients who have had a nephrectomy are eligible for treatment if they have serum creatinine levels £1.5 mg/dL. 
 Patients with normal cardiovascular, pulmonary, hepatic, and CNS function may experience serious life threatening or fatal adverse events. Adverse events are frequent, often serious, and
sometimes fatal. 
 Capillary leak syndrome (CLS) begins immediately after PROLEUKIN* (aldesleukin) treatment
starts and is marked by increased capillary permeability to protein and fluids and reduced vascular tone. In most patients, this results in a concomitant drop in mean arterial blood pressure within 2 to 12 hours after the start of treatment. With
continued therapy, clinically significant hypotension (defined as systolic blood pressure below 90 mm Hg or a 20 mm Hg drop from baseline systolic pressure) and hypoperfusion will occur. In addition, extravasation of protein and fluids into the
extravascular space will lead to the formation of edema and creation of new effusions. 
 Medical management of
CLS begins with careful monitoring of the patient’s fluid and organ perfusion status. This is achieved by frequent determination of blood pressure and pulse, and by monitoring organ function, which includes assessment of mental status and urine
output. Hypovolemia is assessed by catheterization and central pressure monitoring. 
 Flexibility in fluid and
pressor management is essential for maintaining organ perfusion and blood pressure. Consequently, extreme caution should be used in treating patients with fixed requirements for large volumes of fluid (e.g., patients with hypercalcemia). 

Administration of IV fluids, either colloids or crystalloids is recommended for treatment of hypovolemia. IV fluids are
usually given when the central venous pressure (CVP) is below 3 to 4 mm H2O. Correction of hypovolemia may require large volumes of IV fluids but caution is required because unrestrained fluid administration may exacerbate problems associated with
edema formation or effusions. 
 With extravascular fluid accumulation, edema is common and ascites, pleural or
pericardial effusions may develop. Management of these events depends on a careful balancing of the effects of fluid shifts so that neither the consequences of hypovolemia (e.g., impaired organ perfusion) nor the consequences of fluid accumulations
(e.g., pulmonary edema) exceeds the patient’s tolerance. 
 Clinical experience has shown that early
administration of dopamine (1 to 5 μg/kg/min) to patients manifesting capillary leak syndrome, before the onset of hypotension, can help to maintain organ perfusion particularly to the kidney and thus preserve urine output. Weight and urine
output should be carefully monitored. If organ perfusion and blood pressure are not sustained by dopamine therapy, clinical investigators have increased the dose of dopamine to 6 to 10 μg/kg/min or have added phenylephrine hydrochloride (1 to
5 μg/kg/min) to low dose dopamine. Prolonged use of pressors, either in combination or as individual agents, at relatively high doses, may be associated with cardiac rhythm disturbances. If there has been excessive weight gain or edema
formation, particularly if associated with shortness of breath from pulmonary congestion, use of diuretics, once blood pressure has normalized, has been shown to hasten recovery. NOTE: Prior to the use of any product mentioned, the physician should
refer to the Product Monograph for the respective product. 
 PROLEUKIN treatment should be withheld for failure
to maintain organ perfusion, as demonstrated by altered mental status, reduced urine output, a fall in the systolic blood pressure below 90 mm Hg or onset of cardiac arrhythmias (see “DOSAGE AND ADMINISTRATION” section, “Dose
Modification” subsection). Recovery from CLS begins soon after cessation of PROLEUKIN therapy. Usually, within a few hours, the blood pressure rises, organ perfusion is restored and reabsorption of extravasated fluid and protein begins.

 Oxygen is given to the patient if pulmonary function monitoring confirms that PaO2 is decreased. 

PROLEUKIN administration may cause anemia and/or thrombocytopenia. Packed red blood cell transfusions have been given both
for relief of anemia and to insure maximal oxygen carrying capacity. Platelet transfusions have been given to resolve absolute thrombocytopenia and to reduce the risk of GI bleeding. In addition, leukopenia and neutropenia are observed. 

PROLEUKIN administration results in fever, chills, rigors, pruritus, and gastrointestinal side effects in most patients
treated at recommended doses. These side effects have been aggressively managed as described in the “ADVERSE REACTIONS” section. 
 Kidney and liver function are impaired during PROLEUKIN treatment. Use of concomitant nephrotoxic or hepatotoxic medications may further increase toxicity to the kidney or liver.

 Mental status changes including irritability, confusion, or depression which occur while receiving PROLEUKIN
may be indicators of bacteremia or early bacterial sepsis, hypoperfusion, occult CNS malignancy, or direct PROLEUKIN-induced CNS toxicity. Alterations in mental status due solely to PROLEUKIN may progress for several days before recovery begins.
Rarely, patients have sustained permanent neurologic deficits (see 
 “ADVERSE REACTIONS” section).

 Exacerbation of preexisting autoimmune disease or initial presentation of autoimmune and inflammatory
disorders has been reported following PROLEUKIN alone or in combination with interferon (see “ADVERSE REACTIONS” section). Impairment of thyroid function, sometimes preceded by hyperthyroidism, has been reported following PROLEUKIN
treatment. Some of these patients required thyroid replacement therapy. Changes in thyroid function may be a manifestation of autoimmunity. Onset of symptomatic hyperglycemia and/or diabetes mellitus has been reported during PROLEUKIN therapy.

 PROLEUKIN enhancement of cellular immune function may increase the risk of allograft rejection in transplant
patients. 
 Laboratory Tests: The following clinical evaluations are recommended for all patients, prior to
beginning treatment and then daily during drug administration. 
 Standard hematologic tests - including complete
blood count (CBC), differential and platelet counts 
 Blood chemistries - including electrolytes, renal and
hepatic function tests 
 Chest x-rays 
 Serum creatinine should be £1.5 mg/dL prior to initiation of PROLEUKIN
treatment. 
 All patients should have baseline pulmonary function tests with arterial blood gases. Adequate
pulmonary function should be documented (FEV1 >2 liters or 375% of predicted for height and age) prior to initiating therapy. All patients should be screened with a stress thallium study. Normal
ejection fraction and unimpaired wall motion should be documented. If a thallium stress test suggests minor wall motion abnormalities further testing is suggested to exclude significant coronary artery disease. 
 Daily monitoring during therapy with PROLEUKIN should include vital signs (temperature, pulse, blood pressure, and
respiration rate), weight, and fluid intake and output. In a patient with a decreased systolic blood pressure, especially less than 90 mm Hg, constant cardiac rhythm monitoring should be conducted. If an abnormal complex or rhythm is seen, an ECG
should be performed. Vital signs in these hypotensive patients should be taken hourly. 
 During treatment,
pulmonary function should be monitored on a regular basis by clinical examination, assessment of vital signs and pulse oximetry. Patients with dyspnea or clinical signs of respiratory impairment (tachypnea or rales) should be further assessed with
arterial blood gas determination. These tests are to be repeated as often as clinically indicated. 
 Cardiac
function should be assessed daily by clinical examination and assessment of vital signs. Patients with signs or symptoms of chest pain, murmurs, gallops, irregular rhythm or palpitations should be further assessed with an ECG examination and cardiac
enzyme evaluation. Evidence of myocardial injury, including findings compatible with myocardial infarction or myocarditis, has been reported. Ventricular hypokinesia due to myocarditis may be persistent for several months. If there is evidence of
cardiac ischemia or congestive heart failure, PROLEUKIN therapy should be held, and a repeat thallium study should be done. 
 Drug Interactions: PROLEUKIN may affect central nervous function. Therefore, interactions could occur following concomitant administration of psychotropic drugs (e.g., narcotics, analgesics, antiemetics, sedatives, and
tranquilizers). 
 Concurrent administration of drugs possessing nephrotoxic (e.g., aminoglycosides,
indomethacin), myelotoxic (e.g., cytotoxic chemotherapy), cardiotoxic (e.g., doxorubicin) or hepatotoxic (e.g., methotrexate, asparaginase) effects with PROLEUKIN may increase toxicity in these organ systems. The safety and efficacy of PROLEUKIN in
combination with any antineoplastics have not been established. 
 In addition, reduced kidney and liver function
secondary to PROLEUKIN treatment may delay elimination of concomitant medications and increase the risk of adverse events from those drugs. 
 Hypersensitivity reactions have been reported in patients receiving combination regimens containing sequential high dose PROLEUKIN and anti-neoplastic agents, specifically, dacarbazine,
cis-platinum, tamoxifen and interferon-alfa. These reactions consisted of erythema, pruritus, and hypotension and occurred within hours of administration of chemotherapy. These events required medical intervention in some patients. Myocardial
injury, including myocardial infarction, myocarditis, ventricular hypokinesia, and severe rhabdomyolysis appear to be increased in patients receiving PROLEUKIN and interferon-alfa concurrently. 
 Exacerbation or the initial presentation of a number of autoimmune and inflammatory disorders has been observed following
concurrent use of interferon-alfa and PROLEUKIN, including crescentic IgA glomerulonephritis, oculo-bulbar myasthenia gravis, inflammatory arthritis, thyroiditis, bullous pemphigoid, and Stevens-Johnson syndrome. 
 Although glucocorticoids have been shown to reduce PROLEUKIN-induced side effects including fever, renal insufficiency,
hyperbilirubinemia, confusion, and dyspnea, concomitant administration of these agents with PROLEUKIN may reduce the antitumor effectiveness of PROLEUKIN and thus should be avoided. 
 Beta-blockers and other antihypertensives may potentiate the hypotension seen with PROLEUKIN. 
 Delayed adverse reactions to iodinated contrast media: A review of the literature revealed that 12.6% (range 11-28%) of 501
patients treated with various interleukin-2 containing regimens who were then subsequently administered radiographic iodinated contrast media experienced acute, atypical adverse reactions. The onset of symptoms usually occurred within hours (most
commonly 1 to 4 hours) following the administration of contrast media. These reactions include fever, chills, nausea, vomiting, pruritus, rash, diarrhea, hypotension, edema, and oliguria. Some clinicians have noted that these reactions resemble the
immediate side effects caused by interleukin-2 administration, however the cause of contrast reactions after interleukin-2 therapy is unknown. Most events were reported to occur when contrast media was given within 4 weeks after the last dose of
interleukin-2. These events were also reported to occur when contrast media was given several months after interleukin-2 treatment. Carcinogenesis, Mutagenesis, Impairment of Fertility: There have been no studies conducted assessing the carcinogenic
or mutagenic potential of PROLEUKIN. 
 There have been no studies conducted assessing the effect of PROLEUKIN on
fertility. It is recommended that this drug not be administered to fertile persons of either gender not practicing effective contraception. 
 Use in Pregnancy: PROLEUKIN has been shown to have embryolethal effects in rats when given in doses at 27 to 36 times the human dose (scaled by body weight). Significant maternal
toxicities were observed in pregnant rats administered PROLEUKIN by IV injection at doses 2.1 to 36 times higher than the human dose during critical period of organogenesis. No evidence of teratogenicity was observed other than that attributed to
maternal toxicity. There are no adequate well-controlled studies of PROLEUKIN in pregnant women. PROLEUKIN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 
 Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk
and because of the potential for serious adverse reactions in nursing infants from PROLEUKIN, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

 Use in Children: Safety and effectiveness in children under 18 years of age have not been established.

 ADVERSE REACTIONS 
 The rate of drug-related deaths in the 255 metastatic RCC patients who received single-agent PROLEUKIN* (aldesleukin) was

 The following life threatening (grade 4) adverse events were
reported by <1% of the 525: reaction unevaluable; hypothermia; shock; bradycardia; ventricular extrasystoles; myocardial ischemia; syncope; hemorrhage; atrial arrhythmia; phlebitis; AV block second degree; endocarditis; pericar-dial effusion;
peripheral gangrene; thrombosis; coronary artery disorder; stomatitis; nausea and vomiting; liver function tests abnormal; gastrointestinal hemorrhage; hematemesis; bloody diarrhea; gastrointestinal disorder; intestinal perforation; pancreatitis;

edema; hyperventilation; hypoxia; hemoptysis; hypoventilation; pneu-mothorax; mydriasis; pupillary disorder; kidney function abnormal; kidney failure; acute tubular necrosis. 
 In an additional population of greater than 1,800 patients treated with PROLEUKIN-based regimens using a variety of doses and
schedules (e.g., subcutaneous, continuous infusion, administration with LAK cells) the following serious adverse events were reported: duodenal ulceration; bowel necrosis; myocarditis; supraventricular tachycardia; permanent or transient blindness
secondary to optic neuritis; transient ischemic attacks; meningitis; cerebral edema; pericarditis; allergic interstitial nephritis; tracheo-esophageal fistula. 
 In the same clinical population, the following events which were fatal or resulted in death each occurred with a frequency of <1%: liver or renal failure; intestinal perforation;
cardiac arrest; myocardial infarction; malignant hyperthermia; pulmonary edema; respiratory arrest; respiratory failure; stroke; pulmonary emboli; severe depression leading to suicide. 
 In world-wide postmarketing experience, the following serious adverse events have been reported in a variety of treatment
regimens that include interleukin-2: hypertension; pneumonia (bacterial, fungal, viral); neutropenia; cholecystitis; colitis; gastritis; hepatitis; hepatosplenomegaly; intestinal obstruction; retroperitoneal hemorrhage; cerebral lesions; cerebral
hemorrhage; encephalopathy; extrapyramidal syndrome; neuralgia; neuritis; neuropathy (demyelination); rhabdomyolysis; myopathy; myositis; hyperthyroidism; anaphylaxis; cellulitis; injection site necrosis; insomnia. Exacerbation or initial
presentations of a number of autoimmune and inflammatory disorders have been reported (see “WARNINGS” section). Persistent but non-progressive vitiligo has been observed in metastatic malignant melanoma patients treated with interleukin-2.
Synergistic, additive and novel toxicities have been reported with PROLEUKIN used in combination with other drugs. Novel toxicities include delayed adverse reactions to iodinated contrast media and hypersensitivity reactions to antineoplastic agents
(see 
 “PRECAUTIONS” section). 
 Experience has shown the following concomitant medications to be useful in the management of patients on PROLEUKIN therapy:
a) standard antipyretic therapy, including non-steroidal anti-inflammatories (NSAIDs), started immediately prior to PROLEUKIN to reduce fever. Renal function should be monitored as some NSAIDs may cause synergistic nephrotoxicity; b) meperidine used
to control the rigors associated with fever; c) H2 antagonists given for prophylaxis of gastrointestinal irritation and bleeding; d) antiemetics and antidiarrheals used as needed to treat other gastrointestinal side effects. Generally these
medications were discontinued 12 hours after the last dose of PROLEUKIN. 
 Patients with in-dwelling central
lines have a higher risk of infection with gram positive organisms. A reduced incidence of staphylococcal infections in PROLEUKIN studies has been associated with the use of antibiotic prophylaxis which includes the use of oxacillin, nafcillin,
ciprofloxacin, or vancomycin. Hydroxyzine or diphenhydramine have been used to control symptoms from pruritic rashes and continued until resolution of pruri-tus. Topical creams and ointments should be applied as needed for skin manifestations.
Preparations containing a steroid (e.g., hydrocortisone) should be avoided. NOTE: Prior to the use of any product mentioned, the physician should refer to the Product Monograph for the respective product. 
 Immunogenicity: Fifty-seven of 77 (74%) metastatic renal cell carcinoma patients treated with an every 8-hour PROLEUKIN
regimen and 33 of 50 (66%) metastatic malignant melanoma patients treated with a variety of IV regimens developed low titers of non-neutralizing anti-PROLEUKIN antibodies. Neutralizing antibodies were not detected in this group of patients, but
have been detected in 1/106 (<1%) patients treated with IV PROLEUKIN using a wide variety of schedules and doses. The clinical significance of anti-PROLEUKIN antibodies is unknown. 
 SYMPTOMS AND TREATMENT OF OVERDOSAGE 
 Side effects following the use of PROLEUKIN*(aldesleukin) appear to be dose-related. Exceeding the recommended dose has been associated with a more rapid onset of expected dose-limiting
toxicities. Symptoms which persist after cessation of PROLEUKIN should be monitored and treated supportively. Life-threatening toxicities may be ameliorated by the intravenous administration of dexamethasone, which may result in loss of the
therapeutic effects of PROLEUKIN. NOTE: Prior to the use of dexamethasone, the physician should refer to the Product Monograph for this product. 
 DOSAGE AND ADMINISTRATION 
 The recommended
PROLEUKIN* (aldesleukin) treatment regimen is administered by a 15- minute IV infusion every 8 hours. Before initiating treatment, carefully review the “INDICATIONS AND CLINICAL USE,” “CONTRAINDICATIONS,” “WARNINGS,”
“PRECAUTIONS,” and “ADVERSE REACTIONS” sections, particularly regarding patient selection, possible serious adverse events, patient monitoring and withholding dosage. 
 The following schedule has been used to treat adult patients with metastatic renal cell carcinoma (metastatic RCC) or
metastatic malignant melanoma. Each course of treatment consists of two 5-day treatment cycles separated by a rest period. 
 600,000 IU/kg (0.037 mg/kg) dose administered every 8 hours by a 15-minute IV infusion for a maximum of 14 doses. Following 9 days of rest, the schedule is repeated for another 14 doses, for a maximum of 28 doses per course, as
tolerated. During clinical trials, doses were frequently withheld for toxicity (see “Clinical Experience” and “Dose Modifications” subsections). Metastatic RCC patients treated with this schedule received a median of 20 of the 28
doses during the first course of therapy. Metastatic malignant melanoma patients received a median of 18 doses during the first course of therapy. 
 Retreatment: Patients should be evaluated for response approximately 4 weeks after completion of a course of therapy and again immediately prior to the scheduled start of the next
treatment course. Additional courses of treatment should be given to patients only if there is some tumor shrinkage following the last course and retreatment is not contraindicated (see “CONTRAINDICATIONS” section). Each treatment course
should be separated by a rest period of at least 7 weeks from the date of hospital discharge. 
 Dose
Modifications: Dose modification for toxicity should be accomplished by withholding or interrupting a dose rather than reducing the dose to be given. Decisions to stop, hold, or restart PROLEUKIN therapy must be made after a global assessment of the
patient. With this in mind, the following guidelines should be used: 
 Retreatment with PROLEUKIN is
contraindicated in patients who experience the following toxicities: 
 Body System

 PHARMACEUTICAL INFORMATION 

PROLEUKIN* (aldesleukin), a human recombinant interleukin-2 product, is a highly purified protein with a molecular weight
of approximately 15,300 daltons. The chemical name is des-alanyl-1, serine-125 human interleukin-2. PROLEUKIN, a lymphokine, is produced by recombinant DNA technology using a genetically engineered E. coli strain containing an analog of the human
interleukin-2 gene. Genetic engineering techniques were used to modify the human interleukin-2 gene, and the resulting expression clone encodes a modified human interleukin-2. This recombinant form differs from native interleukin-2 in the following
ways: a) PROLEUKIN is not glycosylated because it is derived from E. coli; b) the molecule has no N-terminal alanine; the codon for this amino acid was deleted during the genetic engineering procedure; c) the molecule has serine substituted for
cysteine at amino acid position 125; this was accomplished by site specific manipulation during the genetic engineering procedure; and d) the aggregation state of PROLEUKIN is likely to be different from that of native interleukin-2. 
 The in vitro biological activities of the native non-recombinant molecule have been reproduced with PROLEUKIN. 
 PROLEUKIN biological potency is determined by a lymphocyte proliferation bioassay and is expressed in International Units
(IU) as established by the World Health Organization 1st International Standard for Interleukin 2 (human). The relationship between potency and protein mass is as follows: 18 million (18x106) IU PROLEUKIN = 1.1 mg protein Composition:
PROLEUKIN is supplied as a sterile, white to off-white, lyophilized cake in single-use vials intended for intravenous (IV) administration. When reconstituted with 1.2 mL Sterile Water for Injection, USP, each mL contains 18 million IU (1.1 mg)
PROLEUKIN, 50 mg mannitol, and 0.18 mg sodium dodecyl sulfate, buffered with approximately 0.17 mg monobasic and 0.89 mg dibasic sodium phosphate to a pH of 7.5 (range 7.2 to 7.8). The manufacturing process for PROLEUKIN involves fermentation in a
defined medium containing tetracycline hydrochloride. The presence of the antibiotic is not detectable in the final product. PROLEUKIN contains no preservatives in the final product. 
 Stability and Storage Recommendations: Store vials of lyophilized PROLEUKIN in a refrigerator at 2° to 8°C (36°
to 46°F). Avoid exposure to heat and light. 
 Reconstituted or diluted PROLEUKIN is stable for up to 48
hours at refrigerated and room temperatures, 2° to 25°C (36° to 77°F). However, since this product contains no preservative, the reconstituted and diluted solutions should be stored in the refrigerator. 
 Do not use beyond the expiration date printed on the vial. NOTE: This product contains no preservative. 
 Reconstitution: Reconstitution and dilution procedures other than those recommended may alter the delivery and/or
pharmacology of PROLEUKIN and thus should be avoided. 
 1. PROLEUKIN* (aldesleukin) is a sterile, white to
off-white, preservative-free, lyophilized powder suitable for IV infusion upon reconstitution and dilution. EACH VIAL CONTAINS 22 MILLION IU (1.3 MG) OF PROLEUKIN AND SHOULD BE RECONSTITUTED ASEPTICALLY WITH 1.2 ML 
 OF STERILE WATER FOR INJECTION, USP. WHEN RECONSTITUTED AS DIRECTED, EACH ML CONTAINS 18 MILLION IU (1.1 MG) OF PROLEUKIN.
The resulting solution should be a clear, colorless to slightly yellow liquid. The vial is for single-use only and any unused portion should be discarded. 
 2. During reconstitution, the Sterile Water for Injection, USP should be directed at the side of the vial and the contents gently swirled to avoid excess foaming. DO NOT SHAKE. 

3. The dose of PROLEUKIN, reconstituted with Sterile Water for Injection, USP (without preservative) should be diluted
aseptically in 50 mL of 
 5% Dextrose Injection, USP (D5W) and infused over a 15-minute period. 
 In cases where the total dose of PROLEUKIN is 1.5 mg or less (e.g., a patient with a body weight of less than 40 kilograms),
the dose of PROLEUKIN should be diluted in a smaller volume of D5W. 
 Concentrations of PROLEUKIN below 30
μg/mL and above 70 μg/mL have shown increased variability in drug delivery. Dilution and delivery of PROLEUKIN outside of this concentration range should be avoided. 
 4. Glass bottles and plastic (polyvinyl chloride) bags have been used in clinical trials with comparable results; it is
recommended that plastic bags be used as the dilution container since experimental studies suggest that use of plastic containers results in more consistent drug delivery. 
 In-line filters should not be used when administering PROLEUKIN. 
 5. Before and after reconstitution and dilution, store in a refrigerator at 2° to 8°C (36° to 46°F). Do not freeze. Administer PROLEUKIN within 48 hours of reconstitution. The solution should be brought to room
temperature prior to infusion in the patient. 
 6. Reconstitution or dilution with Bacteriostatic Water for
Injection, USP, or 0.9% Sodium Chloride Injection, USP should be avoided because of increased aggregation PROLEUKIN should not be co-administered with other drugs in the same container. 
 7. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration,
whenever solution and container permit. 
 DOSAGE FORMS 
 Availability: PROLEUKIN* (aldesleukin) is supplied as a sterile, white to off-white, preservative-free lyophilized product in
single-use vials containing 22 million IU (1.3 mg) intended for intravenous (IV) administration. When reconstituted with 1.2 mL Sterile Water for Injection, USP, each mL 
 contains 18 million IU (1.1 mg) of PROLEUKIN. Discard unused portion. 
 PHARMACOLOGY 
 Clinical: The pharmacokinetic profile of PROLEUKIN* (aldesleukin) is characterized by high plasma concentrations following a short intravenous infusion, rapid distribution to
extravascular, extracellular space, and elimination from the body by metabolism in the kidneys with little or no bioac-tive protein excreted in the urine. In humans the half lives for distribution and elimination are 13 and 85 minutes, respectively.
A third, slower phase of clearance has been observed in laboratory animals. The relatively rapid clearance rate of interleukin-2 has led to dosage schedules characterized by frequent bolus administrations or infusions. 
 PROLEUKIN is cleared from the body primarily (80-90%) by metabolism to amino acids in the cells lining the proximal
convoluted tubules of the kidneys. Access of the protein to the tubules is apparently by direct filtration at the glomerular membrane of Bowman’s capsule, and by peritubular extraction from the efferent arterioles surrounding the proximal
tubules. This dual mechanism for access to the tubules may account for the normal clearance pattern of interleukin-2 in patients experiencing kidney toxicity with serum creatinine values between 1.5 and 3 mg/dL. Limited data suggest that serum
creatinine greater than 3 mg/dL may correlate with an extended elimination half life. 
 In clinical studies,
PROLEUKIN was diluted in 5% Dextrose Injection, USP (D5W), D5W containing 0.1% human serum albumin (HSA), or 5% HSA in normal saline. Pharmacokinetic studies showed that a higher amount of bioactive drug was found in the circulation of animals dosed
with solutions containing HSA. Preclinical efficacy studies in a murine tumor model showed no differences when the dose was diluted in either 5% HSA in normal saline or 0.1% HSA in D5W. However, it appeared that no difference in either objective
response rate, or on-study mortality were observed in groups of patients receiving PROLEUKIN diluted in different ways. 
 CLINICAL EXPERIENCE 
 Two hundred fifty-five patients with metastatic renal cell cancer
(metastatic RCC) were treated with single agent PROLEUKIN in 7 clinical studies conducted at 21 institutions. Two hundred seventy patients with metastatic malignant melanoma were treated with single agent PROLEUKIN in 8 clinical studies conducted at
22 institutions. Patients enrolled in trials of single agent PROLEUKIN were required to have an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1 and normal organ function as determined by cardiac stress test, pulmonary
function tests, and creatinine ?1.5 mg/dL. Patients with brain metastases, active infections, organ allografts and diseases requiring steroid treatment were excluded. 
 PROLEUKIN was given by 15 min IV infusion every 8 hours for up to 5 days (maximum of 14 doses). No treatment was given on days 6 to 14 and then dosing was repeated for up to 5 days on days
15 to 19 (maximum of 14 doses). These 2 cycles constituted 1 course of therapy. Patients could receive a maximum of 28 doses during a course of therapy. In practice >90% of patients had doses withheld. Metastatic RCC patients received a median of
20 of 28 scheduled doses of PROLEUKIN. Metastatic malignant melanoma patients received a median of 18 of 28 scheduled doses of PROLEUKIN during the first course of therapy. Doses were withheld for specific toxicities (see “DOSAGE AND
ADMINISTRATION” section, “Dose Modifications” subsection and “ADVERSE REACTIONS” section). 
 In the renal cell cancer studies (n=255), objective response was seen in 37 (15%) patients, with 17 (7%) complete and 20 (8%) partial responders. The 95% confidence interval for objective response was 11% to 20%. Onset
of tumor regression was observed as early as 4 weeks after completion of the first course of treatment, and in some cases, tumor regression continued for up to 12 months after the start of treatment. The median duration of response for all
responding patients is 54 months (3 to 131+ months). The median duration for patients with complete responses has not yet been observed and for patients with partial response was 20 months. Twelve patients who achieved a complete response and six
patients who achieved a partial response had responses ongoing at the time of last contact. The median progression-free survival for all responding patients was 55 months. Responses were observed in both lung and non-lung sites (e.g., liver, lymph
node, renal bed occurrences, and soft tissue). Of the 37 responding patients, 12 patients with individual bulky lesions (largest lesion > 25 cm2) and 22 patients with large cumulative tumor burden (total > 26 cm2) achieved responses.

 In the metastatic malignant melanoma studies (n=270), objective response was seen in 43 (16%) patients,
with 17 (6%) complete and 26 (10%) partial responders. The 95% confidence interval for objective response was 12% to 21%. The median duration of response for all responding patients was 9 months (1 to 122+ months); the median duration of
objective complete responses has not been observed and the median duration for partial response was 6 months. Ten patients who achieved a complete response and three patients who achieved a partial response had responses ongoing at the time of last
contact. The median progression-free survival for the 43 responding patients was 13 months. Responses in metastatic malignant melanoma patients were observed in both visceral and non-visceral sites (e.g., lung, liver, lymph node, soft tissue,
adrenal, subcutaneous). Of the 43 responding patients, 14 patients with individual bulky lesions (largest lesion > 25 cm2) and 21 patients with large cumulative tumor burden (total > 25 cm2) achieved responses.

 PROLEUKIN* (aldesleukine) 
 Interleukine-2 22 millions IU/Flacon 
 Norme
pharmaceutique: Modificateur de la réponse biologique 
 ACTIONS, PHARMACOLOGIE CLINIQUE 
 PROLEUKIN* (aldesleukine) est analogue à l’interteukine-2 humaine, et elle est produite par technologie
d’ADN recombinant, elle possède une activité biologique analogue à celle de l’interteukine-2 native humaine. PROLEUKIN possède un pouvoir antitumoral, on ignore par quel mécanisme précis PROLEUKIN
exerce son pouvoir antitumoral chez les animaux et chez les humains. 
 Des études in vitro sur des
lignée cellulaires humaines démontrent les propriétés immunorégulatoires de PROLEUKIN, incluant: a) une mitogénèse accrue des lymphocytes et stimulation d’une croissance à long terme des
lignées cellulaires humaines dépendantes de l’interleukine-2; b) une lymphocytoxicité plus poussée; c) une induction de l’activité des cellules tueuses dites LAK (lymphokine activated killer) et NK
(natural killer); et, d) l’induction de la production d’interféron gamma. 
 L’administration in vivo de PROLEUKIN chez les animaux et les humains entraîne de multiples effets immunologiques liés à la dose. Ces effets comprennent l’activation de l’immunité cellulaire
avec lymphocytose, eosinophilie et thrombocytopénie importantes, et la production de cytokines, dont le facteur de nécrose des tumeurs, IL-1 et l’interféron gamma. Les études in vivo sur des modèles de tumeur
murine ont démontré une inhibition de la croissance de la tumeur. 
 Pharmacocinétique :
PROLEUKIN se compose de micro-agrégats biologiquement actifs, à liaisons non covalentes, dont la taille moyenne est de 27 molécules d’interleukine-2 recombinante. L’agent de solubilité, le dodécytsulfate
de sodium, peut avoir un effet sur les propriétés cinétiques de ce produit. Le profil pharmacocinétique de PROLEUKIN se caractérise par des concentrations plasmatiques élevées suite à une
perfusion intraveineuse (IV) de courte durée, une distribution rapide dans l’espace extravasculaire et par élimination rénale, avec peu à aucune protéine bioactive excrétée dans les urines.

 Les études au cours desquelles PROLEUKIN a été injectée par IV à des
moutons et des humains ont montré qu’une fois la perfusion terminée, environ 30 % de la dose administrée est détectable dans le plasma. Ceci concorde avec les études faites sur les rats à
l’aide de PROLEUKIN radio-marquée qui démontrent une capture rapide (< 1 minute) de la quasi-totalité du marqueur dans les poumons, le foie, les reins et la rate. 
 Les courbes de demi-vie sérique (T1/2) de PROLEUKIN restant dans le plasma sont tirées d’études
conduites sur 52 patients atteints d’un cancer, après qu’ils ont reçu une perfusion IV de 5 minutes. Les études ont montré que chez ces patients, le temps de distribution et d’élimination de T1/2
était respectivement de 13 et 85 minutes. 
 Le taux de clairance relativement rapide de PROLEUKIN a
conduit à des schémas posologiques caractérisés par des perfusions fréquentes et de courte durée. Les taux sériques observés sont proportionnels à la dose de PROLEUKIN. 
 Après la distribution initiale rapide dans les organes, la voie de clairance principale du PROLEUKIN en circulation
est le rein. Chez les humains et les animaux, l’élimination de PROLEUKIN se fait par filtration glomérulaire et par extraction péritubulaire dans le rein. Il est possible que ce double mécanisme de livraison de
PROLEUKIN au tube proximal soit responsable de la préservation de la clairance chez les patients dont les valeurs de créatinine sérique sont en hausse. Plus de 80 % de la quantité PROLEUKIN qui est distribuée
au plasma, éliminée de la circulation et délivrée aux reins se métabolise en acide aminé dans les cellules qui tapissent les tubes contournés proximaux. Chez les humains, le taux de clairance moyen
des patients cancéreux est de 268 mL/mn. 
 INDICATIONS ET UTILISATION CLINIQUE 
 PROLEUKIN* (aldesleukine) est indiquée pour le traitement d’adultes (de 18 ans ou plus) atteints d’un
adénocarcinome rénal métastatique. PROLEUKIN est indiquée pour le traitement d’adultes (de 18 ans ou plus) atteints d’un mélanome malin métastatique. 
 Parmi les 255 patients atteints d’un adénocarcinome rénal métastatique, une réponse
objective fut observée chez 37 des patients (15 %), avec 17 (7 %) patients répondeurs complets (PRC) et 20 (8 %) patients répondeurs partiels (PRP). Parmi les 270 patients atteints d’un mélanome malin
métastatique, une réponse objective fut observée chez 43 des patients (16 %), avec 17 (6 %) patients répondeurs complets et 26 (10 %) patients répondeurs partiels. Avant de prendre part à ces études,
les patients avaient vu leur maladie progresser après avoir suivi des thérapies antérieures. Une majorité des patients (96 %) avaient déjà subi une résection chirurgicale de leur lésion
primaire, un curage ganglionnaire ou montré une zone de récidive. 
 Il est obligatoire de bien
choisir les patients avant d’administrer PROLEUKIN. Voir les sections « CONTRE-INDICATIONS », 
 « AVERTISSEMENTS » et « MISES EN GARDE » en ce qui concerne la sélection des patients, y compris les examens recommandés de la fonction cardiaque et respiratoire et les analyses de laboratoire.

 À ce jour, l’évaluation des études cliniques révèle que les patients
ayant un indice fonctionnel ECOG plus favorable, c’est-à-dire égal à 0, au début du traitement répondent mieux à PROLEUKIN, ils ont un taux de réponse plus élevé et une
toxicité plus faible (voir la section « EFFETS INDESIRABLES »). C’est pourquoi l’évaluation de l’indice fonctionnel doit être inclue lors de la sélection des patients pour le traitement.
L’expérience avec des patients ayant un indice fonctionnel ECOG > 1 est limitée.

 CONTRE-INDICATIONS 
 PROLEUKIN* (aldesleukine) est contre-indiquée chez les patients ayant des antécédents connus d’hypersensibilité à l’interleukine-2 ou tout
autre composant entrant dans la composition de PROLEUKIN. 
 Les patients qui obtiennent des résultats
anormaux à l’épreuve d’effort au thallium ou aux examens de la fonction respiratoire et ceux qui ont des allogreffes d’organe ne doivent pas être traités avec PROLEUKIN. De plus, une réadministration
de PROLEUKIN est contre-indiquée chez les patients qui ont manifesté les toxicités suivantes lors d’une première cure : 
 Tachycardie ventriculaire prolongée (??5 battements) 
 Troubles du rythme cardiaque non maîtrisés ou ne répondant pas 
 Douleur
thoracique récurrente accompagnée de modifications de poitrine ou un infarctus du myocarde 
 Tamponnade cardiaque 
 Intubation exigée > 72 heures 
 Dysfonctionnement rénal exigeant une dialyse > 72 heures 
 Coma ou psychose toxique se prolongeant au-delà de 48 heures 
 Crises à répétitions ou difficiles à calmer 
 Ischémie ou perforation intestinale 
 Hémorragie gastro-intestinale nécessitant une intervention chirurgicale 
 AVERTISSEMENTS 
 PROLEUKIN* (aldesleukine) ne doit
être administrée qu’à des patients ayant été bien informés, dans un cadre hospitalier, sous la surveillance d’un médecin qualifié et rompu au traitement du cancer par agents
thérapeutiques. Une unité de soins intensifs et des spécialistes compétents en médecine cardio-pulmonaire ou en soins intensifs doivent être disponibles. 
 L’administration de PROLEUKIN a été associée au syndrome de fuite capillaire (SFC) qui se
caractérise par la perte de tonicité vasculaire, l’épanchement de protéines et de fluide du plasma dans l’espace extravasculaire. Le SFC entraîne une hypotension et une réduction de
l’irrigation sanguine des organes qui peut être grave et causer la mort. Le SFC peut être associé à des arythmies cardiaques (supraventriculaires et ventriculaires), angine de poitrine, infarctus du myocarde,
insuffisance respiratoire nécessitant une intubation, hémorragie gastro-intestinale ou infarctus de l’intestin, insuffisance rénale, œdème et changements de l’humeur. 
 En raison des effets indésirables graves qui accompagnent généralement le traitement par PROLEUKIN aux
posologies recommandées, une évaluation clinique approfondie doit être effectuée pour identifier les patients qui ont d’importantes insuffisances cardiaques, pulmonaires, rénales, hépatiques ou du
système nerveux central car PROLEUKIN est contre-indiquée chez ces patients. 
 Le traitement par
PROLEUKIN doit être réservé aux patients dont les fonctions pulmonaire et cardiaque sont normales d’après les résultats de l’épreuve au thallium et les examens de la fonction respiratoire. Il faut
faire preuve d’une extrême prudence chez les patients avec des résultats normaux à l’épreuve au thallium et aux examens de la fonction respiratoire qui ont des antécédents de maladie cardiaque ou
pulmonaire. 
 Les patients ayant une fonction cardio-vasculaire, pulmonaire, hépatique et nerveuse
normale peuvent subir des effets indésirables graves, mettant leur vie en danger ou entraînant leur décès. Les effets indésirables sont fréquents, souvent graves et entraînent parfois la mort. Si des
effets indésirables apparaissent et que la dose doit être modifiée, il est préférable d’interrompre le posologie plutôt que de la réduire (voir le paragraphe « Modification de le dose »
dans le section « POSOLOGIE ET ADMINISTRATION »). 
 L’administration de PROLEUKIN a
été associée à une exacerbation d’une maladie auto-immune préexistante ou débutante et des troubles inflammatoires. Une exacerbation des maladies suivantes a été rapportée
après un traitement avec l’IL-2 : maladie de Crohn, sclérodermie, thyroïdite, arthrite inflammatoire, diabète sucré, myasthénie grave oculobulbaire, néphropathie à lgA en forme de croissant,
cholécystite, vascularite cérébrale, syndrome de Stevens-Johnson et pemphigoïde bulleuse. 
 Tous les patients doivent subir une évaluation approfondie, un traitement des métastases du S.N.C. et avoir un scintigramme négatif avant de débuter la PROLEUKIN. De nouveaux signes et symptômes
neurologiques et lésions anatomiques sont apparus à la suite d’un traitement par PROLEUKIN chez des patients qui ne montraient aucune évidence de métastases du S.N.C. Les manifestations cliniques incluent des
changements de l’humeur, troubles de la parole, cécité corticale, ataxie des membres, hallucinations, agitation, obnubilation et coma. Les images obtenues par I.R.M. ont montré de multiples, et moins souvent, de simples
lésions corticales et mis en évidence une démyélinisation. Les signes et symptômes neurologiques associés à la prise de PROLEUKIN disparaissent normalement à l’arrêt du traitement;
cependant, des anomalies neurologiques permanentes ont été signalées. Un cas de vascularite cérébrale, en réponse à la dexaméthasone, a été rapporté. Il faut faire preuve
d’une extrême prudence avec les patients ayant des antécédents de crises épileptiques, du fait que PROLEUKIN peut provoquer des crises d’épilepsie. 
 L’administration de PROLEUKIN doit être suspendue chez les patients qui manifestent des états
léthargiques ou somnolents modérés ou profonds, la poursuite du traitement pouvant entraîner un coma. 
 Le traitement par PROLEUKIN a été associé à une détérioration de la fonction neutrophile (chimiotactisme réduit) et à des risques accrus d’infection
disséminée, y compris les septicémies et endocardites bactériennes. Par conséquent, il importe de traiter convenablement toutes les infections bactériennes préexistantes avant de débuter la
thérapie par PROLEUKIN. Les patients qui ont des lignées germinales à demeure sont particulièrement exposés aux risques d’infection par des micro-organismes Gram positifs. La prophylaxie antibiotique qui a
été associée à une incidence réduite d’infections staphylococciques comprend l’usage d’oxacilline, de nafcilline, de ciprofloxacine ou de vancomycine. Les infections disséminées
acquises durant le traitement par PROLEUKIN contribuent largement à la morbidité liée au traitement et l’utilisation d’une prophylaxie antibiotique et un traitement agressif des infections soupçonnées ou
documentées pourraient réduire la morbidité liée au traitement par PROLEUKIN. REMARQUE : Avant d’utiliser tout produit mentionné dans ce paragraphe, le médecin devra consulter la monographie du produit
utilisé. 
 MISES EN GARDE 
 Mises en garde générales : Les patients doivent avoir une fonction cardiaque, pulmonaire, hépatique et nerveuse normale en début de traitement. Les patients
atteints d’un adénocarcinome rénal métastatique ayant subi une néphrectomie peuvent quand même être admis si leur taux de créatinine sérique est ?1,5 mg/dL. 
 Les patients ayant une fonction cardio-vasculaire, pulmonaire, hépatique et nerveuse normale peuvent subir des effets
indésirables graves, mettant leur vie en danger ou entraînant leur décès. Les effets indésirables sont fréquents, souvent graves et entraînent parfois la mort. Le syndrome de fuite capillaire (SFC.) se
produit immédiatement après le commencement du traitement par PROLEUKIN* (aldesleukine) et se traduit par une augmentation de la perméabilité capillaire aux protéines et aux fluides et par une perte de
tonicité. Chez la plupart des patients, ceci résulte en une chute concomitante de la tension artérielle moyenne dans les 2 à 12 heures qui suivent le début du traitement. Si le traitement est poursuivi, il en
résultera une hypotension significative du point de vue clinique (définie en tant que pression sanguine systolique en dessous de 90 mm Hg ou une chute de 20 mm Hg par rapport à la pression systolique à sa valeur initiale)
et une hypoperfusion s’en suivra. En outre, un épanchement de protéines et de liquides dans l’espace extravasculaire entraînera des œdèmes et de nouveaux épanchements. 
 La prise en charge médicale du syndrome de fuite capillaire commence par une surveillance vigilante de
l’état hydrique et d’irrigation d’organe du patient. Ceci s’accomplit en mesurant fréquemment la tension artérielle et le pouls et en surveillant la fonction des organes, ce qui comprend
l’évaluation de l’état mental et du débit urinaire. L’hypovolémie est évaluée au moyen d’un cathétérisme et en surveillant la pression veineuse centrale. 
 Une gestion souple des fluides et des vasopresseurs est indispensable pour le maintien de l’irrigation d’organe et
de la tension artérielle. Par conséquent, il faudra faire preuve d’une extrême prudence dans le traitement de patients qui exigent ponctuellement de grandes quantités de liquides (par ex. les patients souffrant
d’hypercalcémie). 
 La prise en charge des patients qui ont une hypovolémie implique
l’administration de liquides intraveineux, soit colloïdes, soit cristalloïdes. Les liquides intraveineux sont généralement administrés lorsque le pression veineuse centrale (P.V.C.) est en dessous de 3 à 4
mm H2O. Il se peut qu’il faille employer d’importantes quantités de liquides IV afin de corriger une hypovolémie, mais il faut alors être très prudent car l’administration non limitée de liquides peut
exacerber les problèmes liés à la formation d’œdèmes ou aux épanchements. 
 Lorsqu’il y a une accumulation de liquides extravasculaires, la formation d’œdèmes est commune et des ascites ainsi que des épanchements pleuraux ou péricardiques peuvent se développer. La
prise en charge de ces événements repose sur un équilibre judicieux des effets des échanges hydriques de façon à ce que ni les conséquences de l’hypovolémie (par ex. réduction de
l’irrigation sanguine des organes) ni les conséquences de l’accumulation de liquide (par ex. oedème pulmonaire) ne dépassent la tolérance du patient. 
 L’étude clinique a démontré que l’administration précoce de dopamine (1 à 5
μg/kg/mn) aux patients manifestant un syndrome de fuite capillaire, avant l’apparition de l’hypotension, peut aider à maintenir l’irrigation sanguine de l’organe particulièrement du rein, préservant
ainsi le débit urinaire. Le poids et le débit urinaire doivent être soigneusement surveillés. Si l’irrigation sanguine d’organe et la pression artérielle se sont pas entretenues par une thérapie par
dopamine, les experts cliniciens ont augmenté la dose de dopamine de 6 à 10 μg/kg/mn ou ont ajouté du chlorhydrate de phényléphrine (1 à 5 μg/kg/mn) à une faible dose de dopamine.
L’utilisation prolongée de vasopresseurs, que ce soit un seul ou une combinaison de plusieurs, à des doses relativement élevées peut être associée à des troubles du rythme cardiaque. Il a
été démontré que l’emploi de diurétiques (une fois que la pression artérielle est redevenue normale) accélère le rétablissement dans les cas où il y a eu une prise de poids
excessive ou la formation d’un œdème, notamment associées à un essoufflement dû à une congestion pulmonaire. REMARQUE : Avant d’utiliser tout produit mentionné dans ce paragraphe, le
médecin devra consulter la monographie du produit utilisé. 
 Une irrigation d’organe
insuffisamment maintenue, se traduisant par une modification de la conscience, une réduction du débit urinaire, une chute de la pression systolique au-dessous de 90 mm Hg ou le début d’arythmies cardiaques, entraînera
automatiquement la suspension du traitement par PROLEUKIN (voir le paragraphe « Modification de la dose » dans la section « POSOLOGIE ET ADMINISTRATION »). Le syndrome de fuite capillaire commence à se corriger peu
après la fin du traitement par PROLEUKIN. Normalement, en quelques heures la tension artérielle augmente, l’irrigation sanguine d’organe se rétablit et une réabsorption des liquides et protéines
épanchés commencent à se produire. On administrera de l’oxygène au patient si la surveillance de la fonction respiratoire confirme que la PaO2 a baissé. 
 Il est possible que l’administration de PROLEUKIN cause une anémie et (ou) une thrombocytopénie. On
administre des transfusions d’hématites concentrées, à la fois pour soigner l’anémie et pour garantir un transport d’oxygène maximal. On administre des transfusions de plaquettes pour corriger une
thrombocytopénie absolue et pour réduire les risques d’hémorragie gastro-intestinale. En outre, on observe des leucopénies et des neutropénies. 
 L’administration de PROLEUKIN entraîne des effets secondaires tels que fièvre, frissons, raideurs, prurits
et troubles gastro-intestinaux chez la plupart des patients traités aux doses recommandées. Ces effets secondaires ont été énergiquement maîtrisés de la manière décrite dans la partie
intitulée « EFFETS INDESIRABLES ». 
 Les fonctions rénale et hépatique sont
insuffisantes pendant le traitement par PROLEUKIN. L’utilisation de médicaments concomitants connus pour leurs effets néphrotoxiques ou hépatotoxiques augmente probablement davantage les effets toxiques sur le rein ou le
foie. 
 Les changements d’humeur tels qu’une irritabilité, une confusion ou une
dépression au cours du traitement par PROLEUKIN peuvent être le signal d’une bactériémie ou d’une septicémie bactérienne à ses débuts, d’une hypoperfusion, une malignité
occulte du S.N.C. ou une toxicité du S.N.C. directe provoquée par PROLEUKIN. Les changements d’humeur qui sont uniquement dus à PROLEUKIN peuvent progresser pendant plusieurs jours avant que le rétablissement ne
commence. Il est rare que les patients souffrent d’anomalies neurologiques permanentes (voir la section « EFFETS INDESIRABLES »). 
 Une exacerbation d’une maladie auto-immune pré-existante ou débutante et des troubles inflammatoires a été signalée suite au traitement par
PROLEUKIN employée seule ou en combinaison avec l’interféron (voir la section « EFFETS INDESIRABLES »). Suite au traitement par PROLEUKIN, on a noté une insuffisance de la fonction thyroïdienne qui est
quelquefois précédée d’une hyperthyroïdie. Un petit nombre de ces patients a nécessité une thérapie thyroïdienne de remplacement. Il se peut que cette insuffisance de la fonction
thyroïdienne soit une manifestation d’auto-immunité. L’apparition d’hyperglycémie et (ou) de diabète sucré a été signalée au cours du traitement par PROLEUKIN. Le renforcement de
la fonction d’immunité cellulaire causé par PROLEUKIN peut augmenter les risques de rejet d’allogreffes chez les patients qui ont reçu un transplant. 
 Tests de laboratoire : Les évaluations cliniques suivantes sont recommandées pour tous les patients, avant que
ne commence le traitement, puis quotidiennement pendant la durée d’administration du médicament. 
 Analyses hématologiques standard, y compris hémogramme, formule leucocytaire et numération plaquettaire 
 Analyses de chimie sanguine, y compris ionogramme sanguin, épreuves fonctionnelles hépatiques et rénales 
 Radiographies pulmonaires 
 Le taux de créatinine sérique doit être ?1,5 mg/dL avant de débuter le traitement par PROLEUKIN. 
 Tous les patients doivent passer un examen de la fonction respiratoire à l’état de base avec
gazométrie artérielle. Une fonction pulmonaire 
 adéquate doit être relevée
(FEV1 > 2 litres ou ??75 % du résultat prévu pour un sujet de cette taille et de cet âge) avant de commencer le traitement.Tous les patients doivent subir un dépistage au moyen d’une épreuve d’effort au
thallium. Les résultats doivent montrer une fraction d’éjection normale et un mouvement normal de la paroi. Si l’épreuve au thallium décèle des anomalies du mouvement de la paroi mineure, d’autres
tests sont suggérés afin d’exclure une maladie coronarienne significative. 
 La surveillance
quotidienne pendant le traitement par PROLEUKIN doit inclure la surveillance des signes vitaux (température, pouls, tension artérielle et taux respiratoire), du poids ainsi que de la prise et du rejet des liquides. Chez les patients
dont la tension artérielle est en baisse, notamment en dessous de 90 mm Hg, on doit surveiller en permanence le rythme cardiaque. Si on note un complexe ou un rythme anormal, il faut effectuer un électrocardiogramme. Les signes vitaux
des patients qui sont hypotensifs doivent être mesurés toutes les heures. Pendant le traitement, il faut surveiller de façon routinière la fonction respiratoire par des examens cliniques, l’évaluation des
signes vitaux et oxymétrie du pouls. Les sujets manifestant une dyspnée ou les signes cliniques d’une insuffisance respiratoire (trachypnée ou râles) doivent subir des examens plus poussés par gazométrie
artérielle. On doit répéter ces tests aussi souvent qu’ils seront cliniquement indiqués. La fonction cardiaque doit être mesurée quotidiennement par examen clinique et par évaluation des signes
vitaux. Les patients qui manifestent des signes ou des symptômes de douleurs thoraciques, souffles du cœur, bruits de galop, rythmes cardiaques irréguliers ou de palpitations doivent être soumis à un ECG et une analyse
de la créatine-phosphokinase (CPK). Des lésions myocardiaques ont été rapportées, y compris des observations compatibles avec un infarctus du myocarde ou une myocardite. Une hypocinésie ventriculaire due
à une myocardite peut durer pendant plusieurs mois. Si des examens montrent l’existence d’ischémie ou d’insuffisance cardiaque congestive, il faut arrêter le traitement par PROLEUKIN et procéder de nouveau
à une épreuve au thallium. 
 Interactions médicamenteuses : PROLEUKIN peut affecter la
fonction nerveuse centrale. Par conséquent, des interactions peuvent se produire suite à l’administration concomitante de médicaments psychotropiques tels que narcotiques, analgésiques, antiémétiques,
sédatifs et tranquillisants. 
 L’administration de médicaments ayant des effets
néphrotoxiques (par exemple des aminosides, de l’indométhacine), myélotoxiques (par exemple une chimiothérapie cytotoxique), cardiotoxiques (par exemple la doxorubicine) ou hépatotoxiques (par exemple le
méthotrexate ou l’asparaginase), en concomitance avec PROLEUKIN peut accroître la toxicité dans ces systèmes d’organe. La sécurité et l’efficacité de PROLEUKIN en combinaison avec des
antinéplastiques n’ont pas été établies. 
 De plus, l’insuffisance
rénale et hépatique secondaire au traitement par PROLEUKIN peut retarder l’élimination des médicaments concomitants et augmenter le risque des effets indésirables de ces médicaments. 
 Des réactions d’hypersensibilité ont été rapportées chez les patients recevant des
schémas de combinaisons contenant une dose élevée séquentielle de PROLEUKIN et des agents anticancéreux, notamment de la dacarbazine, du cis-platinum, du tamoxifène et de l’interféron alpha. Ces
réactions consistent en un érythème, un prurit et une hypotension et sont apparues dans les heures qui ont suivi l’administration de la chimiothérapie. Pour certains patients, ces réactions ont demandé
une intervention médicale. Il semble que les lésions myocardiques, y compris un infarctus du myocarde, une myocardite, une hypocinésie ventriculaire et une rhabdomyolyse sévère soient plus nombreuses chez les
patients recevant PROLEUKIN et l’interféron alpha simultanément. 
 Suite à
l’administration concomitante d’interféron alpha et de PROLEUKIN, on a observé l’exacerbation ou le début de nombreux troubles auto-immuns et inflammatoires tels néphropathie à IgA en forme de
croissant, myasthénie grave oculobulbaire, arthrite inflammatoire, thyroïdite, pemphigoïde bulleuse et syndrome de Stevens-Johnson. 
 Bien qu’on ait démontré que les glucocorticoïdes réduisent les effets secondaires provoqués par PROLEUKIN, y compris fièvre, insuffisance
rénale, hyperbilirubinémie, confusion et dyspnée, l’administration concomitante de ces agents avec PROLEUKIN peut limiter l’efficacité antitumorale de PROLEUKIN et doit, par conséquent, être
évitée. 
 Les inhibiteurs B-adrénergiques et autres antihypotenseurs peuvent exacerber
l’hypotension que l’on remarque avec PROLEUKIN. 
 Réactions indésirables à
retardement des produits de contraste iodés : Une analyse de la documentations a révélé que 12,6 % (plage entre 11 et 28 %) des 501 patients traités par divers régimes à base
d’interleukine-2, auxquels on avait ensuite administré des produits de contraste iodés, manifestèrent des réactions indésirables aiguës atypiques. Les symptômes apparaissaient en
général dans les quelques heures (le plus souvent d’une à quatre heures) après l’administration des produits de contraste. Ces réactions comprennent fièvre, frissons, nausée, vomissement,
prurit, éruption cutanée, diarrhée, hypotension, œdème et oligurie. Certains cliniciens ont remarqué que ces réactions ressemblent aux effets secondaires immédiats provoqués par
l’administration d’interleukine-2; on ignore toutefois la cause des réactions indésirables aux produits de contraste suivant un traitement par interleukine-2. On a remarqué que la plupart de ces incidents se
produisaient lorsque des produits de contraste étaient administrés dans les quatre semaines qui suivaient la dernière prise d’interleukine -2. Ces incidents ont également été signalés lorsque les
produits de contraste étaient utilisés plusieurs mois après le traitement à base d’interleukine-2. Carcinogenèse, mutagenèse, altération de la fécondité : Aucune étude
n’a été menée afin d’évaluer le potentiel carcinogénique ou mutagénique de PROLEUKIN. 
 Aucune étude n’a été menée afin d’évaluer les effets de PROLEUKIN sur la fécondité. Par conséquent, le produit ne doit
être administré qu’à des sujets se soumettant à une méthode efficace de contraception. 
 Utilisation pendant la grossesse : Donnée à des rats des doses de 27 à 36 fois celles des humains (calculées par poids corporel), PROLEUKIN a montré avoir des effets mortels sur l’embryon. Des
toxicités maternelles ont été observées chez les rates enceintes chez qui on avait administré PROLEUKIN par injection IV à des doses 2,1 à 36 fois supérieures à la dose humaine durant la
période critique de l’organogenèse. Aucune tératogénicité autre que celle attribuée à la toxicité maternelle n’a été observée. Il n’y a aucune étude
contrôlée adéquate concernant PROLEUKIN chez les femmes enceintes. PROLEUKIN ne doit être administrée durant la grossesse que si le bénéfice potentiel pour la femme enceinte justifie le risque potentiel
pour le fœtus. 
 Utilisation pendant l’allaitement : L’excrétion de PROLEUKIN dans le lait
maternel n’a pas été étudiée. Étant donné qu’un grand nombre de médicaments est excrété dans le lait maternel et en raison du potentiel d’effets indésirables graves
provoqués par PROLEUKIN sur les nourrissons allaités, on doit prendre la décision soit d’arrêter l’allaitement soit d’arrêter le traitement, en tenant compte de l’importance du médicament
pour la mère. 
 Usage pédiatrique : La sécurité et l’efficacité de ce
médicament chez les enfants de moins de 18 ans n’ont pas été établies.

trouble pupillaire; fonction rénale anormale; insuffisance rénale; néphrite interstitielle aiguë. 
 D’autres effets indésirables graves ont été signalés au cours d’une étude à laquelle participaient plus de 1 800 patients traités par des régimes à base de
PROLEUKIN à différentes doses et suivant différents schémas posologiques (par ex : sous-cutané, perfusion continue, administration de cellules LAK). Ces effets incluaient : ulcération duodénale;
nécrose intestinale; myocardite; tachycardie supraventriculaire; cécité permanente ou transitoire secondaire à une névrite optiqué; attaques ischémiques transitoires; méningite;
œdème cérébral; péricardite; néphrite interstitielle allergique;fistule œsophago-trachéale. 
 Parmi ces 1 800 patients, les incidents suivants qui furent mortels ou entraînèrent la mort se sont produits à une fréquence de < 1 % etincluent :insuffisance
hépatique ou rénale;perforation intestinale arrêt cardiaque;infarctus du myocarde hyperthermie maligne;œdèmepulmonaire;arrêt respiratoire;insuffisance respiratoire;accident vasculaire
cérébral;embolie pulmonaire;dépression sévère menant ausuicide. 
 Lors
d’une étude post-marketing menée au niveau international, les effets indésirables suivants ont été rapportés au cours de différents régimes de traitements par interleukine-2 :
hypertension; pneumonie (bactérienne, fongique, virale); neutropénie; cholécystite; colite; gastrite; hépatite; hépato-splénomégalie; obstruction intestinale; hémorragie
rétropéritonéale; lésions cérébrales; hémorragie cérébrale; encéphalopathie; syndrome extrapyramidal; névralgie; névrite; neuropathie
(démyélinisation); rhabdomyolyse; myopathie; myosite; hyperthyroïdie; anaphylaxie; cellulite; nécrose du site d’injection; insomnie. 
 L’exacerbation ou le début de nombreux troubles auto-immuns et inflammatoires ont été rapportés (voir la section 
 « AVERTISSEMENT »). Chez les patients atteints d’un mélanome malin métastatique traités
par interleukine-2, on a observé un vitiligo persistent mais non progressif. Des toxicités synergiques, additives et nouvelles ont été observées lorsque PROLEUKIN est combinée avec d’autres
médicaments. Les toxicités nouvelles incluent des réactions adverses différées aux produits de contraste et des réactions d’hypersensibilité aux agents anticancéreux (voir la section
« MISES EN GARDE »). 
 L’expérience a montré que les médicaments
concomitants peuvent s’avérer utiles dans la prise en charge des patients traités par PROLEUKIN : a) traitement antipyrétique standard, y compris les anti-inflammatoires non stéroïdiens, débuté
immédiatement avant le traitement par PROLEUKIN pour réduire la fièvre. La fonction rénale doit être surveillée étant donné que les anti-inflammatoires non stéroïdiens peuvent causer
une néphrotoxicité synergique; b) mépéridine utilisée pour contrôler les rigueurs associées à la fièvre; c) inhibiteurs de l’H2 donnés pour la prophylaxie de l’irritation
et de l’hémorragie gastro-intestinales; d) antiémétiques et antidïarrhéiques utilisés, le cas échéant, pour traiter les effets secondaires gastro-intestinaux. Généralement, ces
médicaments sont arrêtés 12 heures après la dernière dose de PROLEUKIN. 
 Les
patients qui ont des lignées germinales à demeure sont plus exposés aux risques d’infection par des micro-organismes Gram positifs.9.11 L’incidence réduite d’infections staphylococciques dans les
études sur PROLEUKIN a été associée à l’utilisation d’une antibiothérapie qui inclut l’utilisation de l’oxacilline, de la nafcilline, de la ciprofloxacine ou de la vancomycine.
L’hydroxyzine ou la diphénhydramine ont été utilisées pour contrôler les symptômes d’eczémas prurigineux et continuées jusqu’à la résolution du prurit. Des
crèmes et des pommades locales doivent être appliquées, le cas échéant, pour les manifestations cutanées. Les préparations contenant un stéroïde (par ex. hydrocortisone) doivent être
évitées. REMARQUE : Avant d’utiliser tout produit mentionné dans ce paragraphe, le médecin devra consulter la monographie du produit utilisé. 
 Immunogénicité : Cinquante-sept des 77 (74 %) patients atteints d’un adénocarcinome rénal
métastatique traités avec un régime de PPOLEUKIN administrée toutes les 8 heures et 33 des 50 (66 %) patients atteints d’un mélanome malin métastatique traités avec une variété de
régime d’IV développèrent de faibles titres d’anticorps anti-PROLEUKIN non neutralisants. Des anticorps neutralisants n’ont pas été détectés dans ce groupe de patients, mais ont
été détectés chez 1/106 (<1 %) des patients recevant PROLEUKIN par IV au moyen d’une grande variété de schémas et de doses. On ignore la significativité clinique des anticorps
anti-PROLEUKIN. 
 SYMTÔMES ET TRAITEMENT D’UN SURDOSAGE 
 Les effets indésirables qui suivent l’utilisation de PROLEUKIN* (aldesleukine) semblent liés à la
dose administrée. Un dépassement de la dose recommandée a été associé à un début plus rapide des toxicités limitantes de la dose. Les symptômes qui persistent après
l’arrêt de PROLEUKIN doivent être surveillés et doivent faire l’objet d’un traitement de soutien. Les toxicités qui mettent en danger la vie du patient peuvent être améliorées par
administration intraveineuse de dexaméthasone, qui peut entraîner une perte des effets thérapeutiques de PROLEUKIN. REMARQUE : Avant d’utiliser tout produit mentionné dans ce paragraphe, le médecin devra
consulter la monographie du produit utilisé. 
 POSOLOGIE ET ADMINISTRATION 
 Le régime de traitement recommandé pour PROLEUKIN* (aldesleukine) est administré par perfusion IV de 15
minutes toutes les 8 heures. Avant de débuter le traitement, revoir soigneusement les sections « INDICATIONS ET UTILISATION CLINIQUE », « CONTRE-INDICATIONS », « AVERTISSEMENTS», « MISES EN GARDE
» et « EFFETS INDÉSIRABLES », particulièrement en ce qui concerne la sélection des patients, les possibles effets indésirables graves, la surveillance des patients et la suspension des doses. 

Le schéma posologique suivant a été utilisé pour traiter les patients adultes atteints
d’un adénocarcinome rénal métastatique ou d’un mélanome malin métastatique. Chaque cycle de la cure consiste en deux cycles de traitement de cinq jours interrompus par une période de repos.

 Une dose de 600 000 UI/kg (0,037 mg/kg) fut administré en perfusion intraveineuse de 15 minutes (14
doses maximum) toutes les 8 heures, suivie d’un repos thérapeutique de 9 jours; après ce repos, ce schéma est répété pour 14 nouvelles doses, pour un maximum de 28 doses par cure, tant que les doses
sont tolérées. Durant les études cliniques, les doses furent souvent suspendues pour des raisons de toxicité (voir les paragraphes « Expérience clinique » et « Modifications de la dose »).
Les patients atteints d’un adénocarcinome rénal métastatique et traités avec ce schéma reçurent une moyenne de 20 doses sur les 28 doses prévues au cours de la première cure. Les patients
souffrant d’un mélanome malin métastatique reçurent une moyenne de 18 doses durant la première cure. 
 Réadministration : On doit évaluer une réponse des patients environ 4 semaines après qu’ils ont complété une cure, puis de nouveau immédiatement avant le début
prévu de la cure suivante. Les patients ne pourront recevoir d’autres cures que s’il y a eu une diminution de la 
 taille de leur tumeur suite à la cure effectuée et si une réadministration n’est pas contre-indiquée (voir la section « CONTRE-INDICATIONS »). Chaque cure devra être suivie
d’une période d’au moins 7 semaines de repos thérapeutique, à partir de la date de sortie d’hôpital. 
 Modifications de la dose : Une modification de la dose en raison de la toxicité se fera en suspendant ou en interrompant la dose plutôt qu’en la réduisant. On
décidera d’arrêter, de suspendre ou de reprendre le traitement par PROLEUKIN uniquement après avoir procédé à une évaluation globale du patient. Tenant compte de cela, on devra suivre les lignes
de conduite suivantes :

INFORMATIONS PHARMACEUTIQUES 
 PROLEUKIN*(aldesleukine), l’interleukine-2 humaine recombinante est une protéine fortement purifiée d’un poids moléculaire proche de 
 15 300 daltons. Son nom chimique est des-alanyl-1, sérine 125-interleukine-2 humaine. PROLEUKIN, une lymphokine, est
produite par technologie d’ADN recombinant sur souche d’E. coli dans laquelle se trouve un analogue du gène de l’interleukine-2 humaine. Des techniques de génie génétique ont été
utilisées pour modifier le gène de l’interleukine-2 humaine pour obtenir un clone d’expressivité codé pour l’interteukine-2 humaine modifiée. Cette forme recombinante diffère de
l’interleukine-2 native par : a) absence de glycosylation (production par la souche d’E coli; b) absence d’alanine N-terminale (perte du codon pour l’alanine durant la procédure de génie génétique); c)
la substitution de la cystéïne en position 125 par la sérine; ceci a été obtenu en manipulant le site spécifique durant la procédure de génie génétique et d) l’état
d’agrégation de PROLEUKIN sera vraisemblablement différent de celui de l’interleukine-2 native. 
 L’activité biologique in vitro de la molécule non recombinante native a été reproduite avec PROLEUKIN.1,2 
 Le pouvoir biologique de PROLEUKIN est déterminé par dosage biologique de la prolifération lymphocytaire et s’exprime en Unités Internationales (Ul), selon
la Première norme internationale de l’O.M.S. pour l’interleukine 2 humaine. La relation entre pouvoir et masse protéique est la suivante : 18 millions (18 x 106) UI de PROLEUKIN = 1,1 mg de protéine Composition :
PROLEUKIN se présente sous flacon de lyophilisat stérile, blanc ou blanc cassé, à usage unique destiné à être administré par perfusion intraveineuse (IV). Après reconstitution avec 1,2 mL
d’eau stérile pour préparation injectable, USP (Pharmacopée des États-Unis), chaque mL contient 18 millions Ul (1,1 mg) de PROLEUKIN, 50 mg de mannitol et 0,18 mg de dodécylsulfate de sodium tamponné
avec environ 0,17 mg de phosphate de sodium monobasique et 0,89 mg de phosphate de sodium dibasique à un pH de 7,5 (allant de 7,2 à 7,8). Le procédé de fabrication de PROLEUKIN implique la fermentation dans un milieu
défini contenant du chlorhydrate de tétracycline. La présence de cet antibiotique n’est pas décelable dans le produit fini. PROLEUKIN ne contient aucun conservateur dans le produit fini. Stabilité et
conservation : Conserver les flacons de lyophilisat PROLEUKIN dans le réfrigérateur entre 2° et 8° C (36° et 46° F). Éviter toute exposition à la chaleur et à la lumière. 
 Le produit reconstitué ou dilué PROLEUKIN est stable pendant 48 heures au réfrigérateur ou
à température ambiante, 2° à 25° C (36° à 77° F). Toutefois, comme ce produit ne contient pas de conservateur, les solutions reconstituées et diluées devront être conservées au
réfrigérateur. Ne pas utiliser au-delà de la date de péremption indiquée sur le flacon. REMARQUE : Ce produit ne contient aucun conservateur. 
 Reconstitution : Des procédures de reconstitution et de dilution autres que celles recommandées pourraient
altérer les propriétés de délivrance et/ou pharmacologiques et doivent par conséquent être évitées. 
 1. PROLEUKIN* (aldesleukine) est un lyophilisat stérile, blanc ou blanc cassé, sans conservateur, prévu pour être administré par perfusion IV après
reconstitution et dilution. CHAQUE FLACON CONTIENT 22 MILLIONS UI (1,3 MG) DE PROLEUKIN ET DOIT ÊTRE RECONSTITUÉ DANS DES CONDITIONS ASEPTIQUES AVEC 1,2 ML D’EAU STÉRILE POUR PRÉPARATION INJECTABLE, USP. UNE FOIS
RECONSTITUÉ COMME INDIQUE, CHAQUE ML CONTIENT 18 MILLIONS UI (1,1 MG) DE PROLEUKIN. La solution obtenue doit être un liquide clair, transparent ou légèrement jaunâtre. Le flacon est prévu pour un usage unique
et il faut veiller à jeter toute portion inutilisée du produit. 
 2. Au cours de la
reconstitution, on doit diriger l’eau stérile pour préparation injectable, USP, au contact de la paroi interne du flacon, puis remuer doucement le contenu en tournant pour éviter la formation de mousse excessive. NE PAS
SECOUER. 
 3. La dose de PROLEUKIN, reconstituée avec de l’eau stérile pour
préparation injectable, USP (sans conservateur) doit être diluée dans des conditions aseptiques dans 50 mL de 5 % de dextrose pour préparation injectable, USP (D5W) et administrée par perfusion intraveineuse
pendant 15 minutes. 
 Dans les cas où la dose totale de PROLEUKIN est de 1,5 mg ou moins (par ex. un
patient dont le poids est inférieur à 40 kilogrammes), la dose de PROLEUKIN doit alors être diluée dans un plus petit volume de D5W. 
 Les concentrations de PROLEUKIN inférieures à 30 μg/mL et supérieures à 70 μg/mL ont montré des variabilités croissantes lors de la
délivrance du médicament. Une dilution et une délivrance de PROLEUKIN en dehors de ces plages doivent être évitées. 
 4. Bien qu’on ait utilisé avec des résultats comparables des flacons de verre et des poches en plastique (chlorure de polyvinyle) pendant les essais cliniques, il est
recommandé de choisir les poches en plastique comme récipient de dilution; en effet, des études expérimentales ont indiqué qu’on obtenait une délivrance du médicament plus homogène avec
les poches en plastique. On ne doit pas employer de filtres internes intratubulaires pendant l’administration de PROLEUKIN. 
 5. Avant et après reconstitution et dilution, conserver au réfrigérateur entre 2° et 8° C (36° et 46° F). Ne pas congeler. Administrer PROLEUKIN dans les 48 heures qui suivent la
reconstitution. La solution doit être amenée à température ambiante avant d’être administrée au patient. 
 6. Il faut éviter de reconstituer ou de diluer le lyophilisat avec de l’eau bactériostalique pour préparation injectable, USP, ou 0,9 % de chlorure de sodium pour
préparation injectable, USP en raison de l’hyperagrégabilité qui en résulte. PROLEUKIN ne doit pas être mélangée dans un même récipient avec d’autres médicaments.

 7. Avant de commencer l’administration, inspecter visuellement, chaque fois que la solution et le flacon
le permettent, les produits pharmaceutiques parentéraux pour déceler d’éventuelles particules ou décolorations. 
 FORMES POSOLOGIQUES 
 Forme : PROLEUKIN*
(aldesleukine) est fournie sous forme de lyophilisat stérile, blanc ou blanc cassé, sans conservateur. Chaque flacon à usage unique contient 22 millions UI (1,3 mg) et est destiné à une administration par injection
intraveineuse (IV). Une fois reconstitué avec 1,2 mL d’eau stérile pour préparation injectable, USP, chaque mL contient 18 millions UI (1,1 mg) de PROLEUKIN. Jeter toute portion non utilisée. 
 PHARMACOLOGIE 
 Clinique : Le profile pharmacocinétique de PROLEUKIN* (aldesleukine) se caractérise par des concentrations plasmatiques élevées suite à une perfusion
intraveineuse (IV) de courte durée, une distribution rapide aux espaces extravasculaire et extracellulaire et par élimination rénale, avec peu ou aucune protéine bioactive excrétée dans les urines. Chez les
sujets humains, la demi-vie de distribution et d’élimination sont respectivement de 13 et 85 minutes. On a observé une troisième phase de clairance, plus lente, chez l’animal de laboratoire. Le taux de clairance
relativement rapide de l’interleukine-2 a donné lieu à des schémas posologiques se caractérisant par une administration sous forme de bolus fréquents de médicament ou de perfusions. 
 PROLEUKIN est éliminée de l’organisme en majeure partie (80 à 90 %) par métabolisme en
aminoacides dans les cellules qui tapissent le tube proximal contourné des reins. Il apparaît que les protéines accèdent à ce tube par infiltration directe au travers de la membrane glomérulaire de la capsule
de Bowman, ainsi que par une extraction péritubulaire des artérioles efférentes qui entourent le tube proximal. Il est possible que ce double mécanisme d’accès au tube proximal permette le schéma normal
d’élimination de l’interleukine-2 chez les patients qui ont une toxicité rénale avec des valeurs de créatinine sérique entre 1,5 et 3 mg/dL. Le peu de données dont on dispose suggère que la
créatinine sérique supérieure à 3 mg/dL puisse avoir une corrélation avec une demi-vie d’élimination prolongée. 
 Dans les études cliniques, PROLEUKIN a été diluée dans 5 % de dextrose pour préparation injectable, USP (D5W), D5W contenant 0,1 % de
sérum-albumine humaine (SAH) ou 5 % de SAH. Les études pharmacocinétiques montrent qu’on retrouve des quantités plus élevées du médicament bioactif dans la circulation d’animaux dont
les doses contiennent de la BAH dans une solution saline normale. Des études précliniques sur l’efficacité sur un modèle de tumeur murine n’indiquent aucune différence, que les doses aient
été diluées dans 5 % de BAH dans une solution salée normale ou dans 0,1 % de BAH dans D5W.Toutefois, il semblerait qu’il n’y ait aucune différence du taux de réponses objectives ou du taux de
mortalité en cours d’étude entre les groupes de patients recevant PROLEUKIN diluée de différentes façons. 
 EXPÉRIENCE CLINIQUE 
 Deux cent
cinquante-cinq patients atteints d’un adénocarcinome rénal métastatique furent traités par agent unique PROLEUKIN au cours de 
 7 études cliniques conduites dans 21 établissements. Deux cent soixante-dix patients atteints d’un mélanome malin métastatique furent traités par
agent unique PROLEUKIN au cours de 8 études cliniques conduites dans 22 établissements. Pour pouvoir prendre part à ces études, les patients devaient avoir un indice fonctionnel (IF) égal à 0 ou 1 tel que le
définit le Eastern Cooperative Oncology Group (ECOG) et une fonction d’organe normale définie par une épreuve d’effort cardiaque, des examens de la fonction respiratoire et un taux de créatinine ?1,5 mg/dL. Les
patients avec des métastases cérébrales, des infections actives, allogreffes d’organes et des maladies exigeant un traitement à base de stéroïde furent exclus des études. 
 PROLEUKIN fut administrée par perfusion IV de 15 minutes toutes les 8 heures pendant un maximum de 5 jours (14 doses
maximum). Le traitement fut suspendu du 6e au 14e jour inclusivement, puis le schéma posologique fut répété pendant un maximum de 5 jours du 15e au 19e jour (14 doses maximum). Ces deux cycles ont constitué une
cure. Durant une cure, les patients pouvaient recevoir un maximum de 28 doses. En fait, plus de 90 % des patients n’ont pas reçu toutes les doses. Les patients atteints d’un adénocarcinome rénal
métastatique reçurent une moyenne de 20 à 28 doses prévues de PROLEUKIN. Les patients souffrant d’un mélanome malin métastatique reçurent une moyenne de 18 à 28 doses prévues de
PROLEUKIN durant la première cure. Les doses furent suspendues en raison de toxicités spécifiques (voir le paragraphe 
 « Modification de la dose » dans la section « POSOLOGIE ET ADMINISTRATION » et la section « EFFETS INDESlRABLES »). 
 Parmi les 255 patients atteints d’un adénocarcinome rénal métastatique, une réponse
objective fut observée chez 37 des patients (15 %), avec 
 17 (7 %) patients répondeurs complets
(PRC) et 20 (8 %) patients répondeurs partiels (PRP). L’intervalle de confiance de 95 % pour la réponse objective fut compris entre 11 % et 20 %. On a pu observer un début de régression tumorale dès
les 4 semaines suivant la fin de la première cure et, dans certains cas, la régression a continué jusqu’à 12 mois après le début du traitement. La durée moyenne des réponses de tous les
patients qui ont répondu est de 54 mois (3 à + de 131 mois). La durée moyenne des réponses complètes objectives n’a pas été observée et pour la réponse partielle, elle fut de 20
mois. Douze des patients qui avaient atteint une réponse complète et six de ceux qui avaient atteint une réponse partielle avaient des réponses en cours au moment de la dernière visite. La survie moyenne sans
progression pour tous les patients répondeurs fut de 55 mois. Les réponses furent observées sur les sites pulmonaires et non pulmonaires (par ex. foie, ganglion lymphatique, phénomènes de lit rénaux et tissu
mou). Sur les 37 patients répondeurs, 12 patients avec de grosses lésions individuelles (la lésion la plus grande étant 325 cm2) et 22 patients avec un grand nombre de tumeurs
cumulatives (total 325 cm2) ont eu des réponses. 
 Parmi les
270 patients atteints d’un mélanome malin métastatique, une réponse objective fut observée chez 43 des patients (16 %), avec 17 
 (6 %) patients répondeurs complets et 26 (10 %) patients répondeurs partiels. L’intervalle de confiance de 95 % pour la réponse objective fut compris entre
12 % et 21 %. La durée moyenne de le réponse objective (partielle ou complète) fut de 9 mois (1 à 122+ mois); la durée moyenne des réponses complètes objectives n’a pas été
observée et pour la réponse partielle, elle fut de 6 mois. Dix des patients qui avaient atteint une réponse complète et trois de ceux qui avaient atteint une réponse partielle avaient des réponses en cours
au moment de la dernière visite. La survie moyenne sans progression pour tous les 43 patients répondeurs fut de 13 mois. Les réponses furent observées sur les sites viscéraux et non viscéraux (par ex.
poumon, foie, ganglion lymphatique, tissu mou, surrénal et sous-cutané). Sur les 43 patients répondeurs, 14 patients avec de grosses lésions individuelles (la lésion la plus grande étant 325 cm2) et 21 patients avec un grand nombre de tumeurs cumulatives (total 325 cm2) ont eu des réponses.

Agreement, and such rights and obligations shall be retained by Novartis. From and after the Effective Date, Novartis shall have no further liabilities or obligations under the Product Purchase Agreement with respect to Proleukin. Notwithstanding
anything herein to the contrary, (a) Prometheus shall have no liability for any Claim or obligation arising out of or in connection with: (i) the Product Purchase Agreement prior to the Effective Date, or (ii) the Excluded
Liabilities, and in each case (i) and (ii), Novartis shall indemnify the Prometheus Indemnitees in connection with any such Claims or obligations in accordance with Section 7.1 of the Distribution Agreement;

 2. Further Actions. Each of the parties hereto covenants and agrees to do, execute, acknowledge and deliver, at the request of the
other party hereto, all such further acts, assurances, deeds, assignments, transfers, conveyances and other instruments and papers as may be reasonably required or appropriate to carry out the assignments and assumptions contemplated by this

 Background 
 As a part of the Novartis’ requirements for compliance with the Deficit Reduction Act II (DRA II), Novartis requires prescription data and pricing for coupon, voucher and Patient Assistance Programs. This document
reviews the overall process and desired data formats to support this process. 
 Overview of Process 

To provide additional background on the fulfillment process, this section provides high level steps of the activities in
and around the fulfillment processes. 
 1.1.1. Campaign Setup Example of DENDRITE 
 1. Campaign definitions (Campaign, Fulfillment, and Segment names, descriptions, dates and relationships) are entered in TACT

 2. Campaign specifications (which Individuals qualify for which Fulfillment or Solicitation) are provided to
Harte Hanks from Novartis using the existing business process. 
 3. Harte Hanks creates an extract and sends to
Vendor (Dendrite) the individuals who qualify for the campaign using the existing technical process. Harte Hanks and IRMA record the fulfilled records as a contact event. 
 1.1.2. Campaign Execution/Fulfillment 
 4. VENDOR
executes the campaign to the individuals provided and creates an acknowledgement file with the individuals provided. 
 5. Consumers use the card, and Vendor collects card activity associated with the usage. 
 6.
Harte Hanks and IRMA store the data as needed in their database as contact events. 
 1.1.3. Campaign Analysis

 7. Novartis loads the data to IRMA and EDNA for reporting and analysis purposes. 
 1.1.4. Government Pricing Reporting 
 8. Novartis loads the data to the Imany Government Pricing system for use in calculations of Best Price Possible, Best Price Achieved and Average Manufacturers Price, per the Deficit
Reduction Act regulations.

Authorizations, to change the Packaging Information in which or with which it chooses to have Novartis deliver the Product, any such change being referred to as an “Artwork Change”; provided, however, that (i) any
such change occasioned by requirements of Applicable Law, safety considerations, or the request of any Regulatory Authority shall be implemented as soon as reasonably possible and as required by Applicable Law, and (ii) for any other Artwork
Change Novartis will use Commercially Reasonable Efforts to accommodate the Prometheus time schedule, subject at all times to its agreements with Third Party contractors. In the event that Novartis implements an Artwork Change at the request of
Prometheus, all direct out-of-pocket costs and expenses reasonably incurred by Novartis or its Affiliates (including any reasonably incurred, direct, out-of-pocket costs of or payable to a Subcontractor) in connection with such Artwork Change shall
be paid by Prometheus within forty-five (45) days of the date of an invoice therefor. 
 (e) All Packaging Information,
including Packaging Information resulting from an Artwork Change, which contains the name of Novartis or its Affiliates (other than solely identifying Novartis or its Affiliates or their Subcontractors as the manufacturer or supplier of the Product)

 ***Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 7 

 (ii) Prior to December 31, 2011, the Parties shall negotiate in good
faith, taking into account among others the market conditions for the Product, sales levels in the Territory and/or any Significant Market Event, new Annual Minimum Order Purchase Requirements and Penalty Breach for the following Calendar Years
during the remainder of the Term. The Parties agree that if no agreement is reached within two (2) months from the start of such negotiations, the matter in dispute shall be escalated to the Joint Development Committee, which shall make a final
decision not more than one (1) month since the matter was escalated; and 
 (iii) Should Prometheus fail to
purchase the Annual Minimum Order Purchase Requirements during any Calendar Year, and subject to this Section 3.1(a), as Novartis’ sole remedy with respect to any Penalty Breach, Prometheus shall pay to Novartis [***] US Dollars ($[***])
per each Batch (or [***] US Dollars ($[***]) per half batch) it has failed to purchase in any given Calendar Year in accordance with the Annual Minimum Order Purchase Requirements agreed upon by the Parties (the “Penalty Breach”).

 (b) Maximum Annual Capacity. Prometheus understands and agrees that Novartis and/or its Affiliates and Subcontractors
have a maximum capacity reservation for manufacturing the Product per Calendar Year. In this regard, the Parties agree that Novartis’ maximum annual capacity per Calendar Year for the Term shall be [***] ([***]) Batches of Product (the
“Maximum Annual Capacity”). 
 (c) Order Quantities. Prometheus shall place Purchase Orders which are
multiples of half a Batch (i.e. [***] ([***]) vials). 
 3.2 Rolling Forecasts. On or before the Effective Date,
and at least five (5) Business Days prior to first Business Day of each Calendar Quarter thereafter during the Term, Prometheus shall deliver to Novartis a written rolling [***] ([***]) month forecast of the amount of Product that Prometheus
expects in good faith to order. The Parties agree that the first [***] ([***]) months of such rolling forecast shall be considered as binding for Prometheus. The Product volumes specified for the [***] ([***]) through [***] ([***]) month of each
forecast shall be non-binding estimates of future Product requirements. When preparing the forecast, Prometheus shall use Commercially Reasonable Efforts to (i) apportion its requirements of Product in a reasonable manner in order to minimize
untoward fluctuation in Novartis’ or its Subcontractors’ production scheduling, and (ii) allocate quantities among Product to be sold in the U.S. and Product to be sold in Canada. 
 3.3 Orders. 
 (a) During the Term, Prometheus or any of its Affiliates shall place written purchase orders (each a “Purchase Order”) for Product, not less than [***] ([***]) days prior to the Prometheus specified delivery date in
accordance with the [***] ([***]) month binding forecast mentioned in Section 3.2 above. Each Purchase Order shall specify any country-specific Specifications, presentations, and packaging and labeling requirements under Applicable Law or
otherwise requested by Prometheus and any other relevant information. 
  
 ***Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

 (b) Within sixty (60) days from the Effective Date, the Parties shall mutually agree
upon the logistics of the forecasting, ordering and delivery process (“Trading Services Procedure”), including names of contact persons for each Party, addresses. A sample form of Purchase Order is attached hereto as Exhibit 1. The
Trading Services Procedure cannot be amended without the written agreement of the Parties. 
 (c) Novartis will accept all
Purchase Orders that comply with this Section 3.3; provided, however, that in the event that any Purchase Order, alone or when aggregated with all other Purchase Orders for the same Calendar Year, exceeds the Maximum Annual
Capacity, Novartis shall not be required to fulfill Product ordered under such Purchase Order. Purchase Orders will be accepted or rejected via written notice of acceptance or rejection by Novartis to Prometheus. Novartis shall use Commercially
Reasonable Efforts to send notice of rejection or acceptance to Prometheus as soon as reasonably practicable, provided that such notice must be given no later than [***] calendar days after receipt of the Purchase Order. In the event Prometheus does
not receive a notice of rejection within such period, the applicable Purchase Order shall be deemed to have been accepted by Novartis. 
 (d) Novartis shall use Commercially Reasonable Efforts to supply Product pursuant to each accepted Purchase Order in a timely manner; provided, that each order will be deemed to have been fully satisfied, as to quantity, if the
quantity of Products actually delivered to Prometheus is between [***] percent ([***]%) and [***] percent ([***]%) of the quantity of Products set forth in the relevant Purchase Order, and in such event, Prometheus shall be required to pay for the
amount of conforming Product actually received in accordance with Article 5; provided, further, that Novartis will use Commercially Reasonable Efforts to supply [***] percent ([***]%) of the quantity of Products ordered. 
 (e) From time to time, due to significant unforeseen circumstances, and upon previous written agreement of the Parties (e.g.: e-mail
and/or facsimile), Prometheus may request, and Novartis may deliver Product volumes in excess of those specified in any binding forecast or with delivery dates shorter than the periods specified in subsection (a) above. Prior to such written
agreement, Novartis shall notify Prometheus whether, using Commercially Reasonable Efforts, it can provide Prometheus with such excess Product volumes or by such expedited delivery date, provided that if compliance with such request would result in
Novartis incurring additional incremental costs, Novartis shall so notify Prometheus of such estimated costs, whereupon Prometheus shall, at its option either: (i) agree to reimburse Novartis for such additional incremental costs (including for
any expatiated means of shipping), or (ii) promptly amend its Purchase Order to reduce its order quantity to the forecast amount or adjust its delivery dates to comply with subsection (a), as applicable. 
 3.4 Shipment. 
 (a) The Product to be delivered pursuant to the accepted Purchase Orders shall be delivered FCA (Incoterms 2000) to a single Prometheus-designated delivery location in the United States. Prometheus shall be responsible for distribution from
this United States site to any other locations. All Products shall be shipped in accordance with the Specifications and Applicable Law.

 (b) Novartis shall use Commercially Reasonable Efforts to expedite all shipments of Product
to Prometheus. 
 3.5 Late Delivery. 
 (a) Novartis shall use Commercially Reasonable Efforts to meet the delivery dates and order quantities indicated in the Purchaser Orders accepted pursuant to Section 3.3. If any circumstances occur
that could reasonably be expected to result in any delivery delay or variation in quantity exceeding that set forth in Section 3.3(d), Novartis shall, as soon as reasonably practicable, inform Prometheus thereof in sufficient detail for
Prometheus to assess the likelihood that such delivery delay or variation in quantity will adversely affect its inventory situation. Any shipment delivered that is within plus or minus [***] percent (+/-[***]%) of the quantity ordered and/or plus or
minus [***] (+/-[***]) Business Days of the delivery date specified on the relevant accepted Purchase Order will be considered as delivered on time. 
 (b) In the event that Novartis is unable or otherwise fails to deliver Product pursuant to the applicable Purchase Order on time (as provided in the last sentence of subsection (a) of this
Section 3.5), Novartis shall be deemed to have committed a “Purchase Order Failure”. In the event of a Purchase Order Failure, Novartis shall, as soon as reasonably possible (and in any event not later than [***] from the
stated delivery date in the confirmed Purchase Order), notify Prometheus in writing of such Purchase Order Failure, which notice (a “Purchase Order Failure Notice”) shall inform Prometheus of the date on which Novartis reasonably
expects to be able to deliver the Product subject to the Purchase Order Failure Notice (the “Purchase Order Default Supplies”) to Prometheus. Novartis shall [***] deliver the delayed Purchase Order Default Supplies promptly after
the date of the Purchase Order Failure. Where and to the extent that any Purchase Order Failure is due to any Non-Conformity, and regardless of whether such Non-Conformity is detected by Novartis prior to release or shipment of the applicable
Products or by Prometheus following delivery in accordance with the rejection procedure set forth in Sections 4.2 and 4.3, following a determination of such Non-Conformity Novartis shall be required to manufacture and deliver new Product to
Prometheus in accordance with Prometheus’ ordered requirements as soon as reasonably practicable (and in any event shall commence manufacture not later than [***] ([***]) days) after such final determination. Where and to the extent that
Prometheus suffers any damages as a result of any Purchase Order Failure, notwithstanding, the provisions of Section 3.5(c) below, Prometheus shall, upon receipt of delayed Products, at its option and by written notice to Novartis, either
(i) receive the corresponding price discount on the Actual Price for such late delivered Product, as established in Section 3.5(c) below; or (ii) have such rights and remedies as are afforded to at law or in equity, and/or as
otherwise afforded to it under the Distribution Agreement. Notwithstanding anything set forth herein, Prometheus shall have a duty to use Commercially Reasonable Efforts to mitigate any damages which it may suffer as a result of any Purchase Order
Failure. 
 (c) In the event that a Purchase Order Failure causes any Product to be delivered more than [***] after the delivery
date for such Product specified in the applicable Purchase Order therefore, Prometheus shall be entitled to receive a [***] percent ([***]%) discount on the Actual Price for such late delivered Product which would otherwise have been payable
pursuant to Article 5. In the event that a Purchase Order Failure causes any Product to be delivered more than [***] after the delivery date for such Product specified in the applicable Purchase Order therefore, Prometheus shall be entitled to
receive a [***] percent ([***]%) discount on the Actual Price for such late delivered Product which would otherwise have been payable pursuant to Article 5. In the event that a Purchase Order Failure causes any Product to

 10 

 
be delivered more than [***], after the delivery date for such Product specified in the applicable Purchase Order therefore, Prometheus shall be entitled to receive a [***] percent ([***]%)
discount on the Actual Price for such late delivered Product which would otherwise have been payable pursuant to Article 5. Any discount amount owing to Prometheus pursuant to this Section 3.5(c) shall be paid, at Prometheus’ option,
either by (a) reflecting such amount as a reduction in the Actual Price in Novartis’ invoice for such Product subject to the late delivery, (b) granting Prometheus a credit against any future invoices for Product until the applicable
discount amount has been fully applied, or (c) paying Prometheus such amount in cash, by check or via other payment method acceptable to Prometheus. 
 3.6 Alternate Manufacturer. Following the Effective Date, Novartis and Prometheus shall work together in good faith to reasonably determine whether an alternative supplier of the Products (an
“Alternate Manufacturer”) is appropriate or necessary at any time during the Term. If agreed upon by both Parties, Novartis and Prometheus shall cooperate in good faith to perform all necessary activities required to establish and qualify
such Alternate Manufacturer. 
 ARTICLE IV 
 QUALITY ASSURANCE AND CHANGE MANAGEMENT 
 4.1 QA Agreement.
Within sixty (60) days from the Effective Date, the Parties shall negotiate in good faith and execute a QA Agreement in connection with this Agreement (the “QA Agreement”) which addresses the management of the quality elements
related to the Product. In the event of any conflict between the terms of this Agreement and the QA Agreement, this Agreement shall prevail. 
 4.2 Rejected Product. Prometheus shall use Commercially Reasonable Efforts to visually inspect each shipment of Product delivered to it hereunder for visible damage. In the event Novartis supplies
any Product to Prometheus and it is established that such Product is Non-Conforming, the following shall apply: 
 (i)
Prometheus shall promptly notify Novartis in writing within [***] Business Days after receipt of such Non-Conforming Product, or in the case of any concealed or latent Non-Conformity, promptly in writing within [***] Business Days upon discovery of
such Non-Conformity (the “Rejected Product”); 
 (ii) If no notification is made as stated in subsection
(i) above, subject to subsection (v) below, Prometheus will be deemed to have accepted any delivered Product, provided that any failure to timely reject any Non-Conforming Product shall not affect Prometheus’ ability to make a breach
of warranty claim or otherwise seek indemnification from Novartis pursuant to this Agreement, other than with respect to any Non-Conformity which a timely inspection would have discovered if Prometheus or its designated agent adhered to its standard
SOPs for incoming inspection for products similar to the Product. 
  
 ***Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 11 

 (iii) Prometheus shall return the Non-Conforming Product to Novartis or destroy it, as per
Novartis’ written request and instructions and at Novartis’ sole cost and expense; 
 (iv) Subject to subsection
(v) below, provided that Prometheus returns or destroys Rejected Product to Novartis in accordance with subsection (iii) and, upon Novartis written request, delivers to Novartis a certified destruction report of the Rejected Product (if
applicable), Novartis shall promptly credit Prometheus an amount equal to the price paid by Prometheus for such Rejected Product, including but not limited to all freight, duties, taxes and insurance charges incurred by Prometheus in connection with
the delivery of the Rejected Product; 
 (v) In the event that any concealed or latent defect causing the Non-Conformity is
attributable to the actions, omissions or breach of this Agreement by Prometheus, Novartis shall not have any responsibility for the purchase price credit for such Rejected Product nor bear any other costs, including but not limited to all freight,
duties, taxes and insurance charges in connection with the delivery of new conforming Product, and Prometheus shall, irrespective of such latent defect or Non-Conformity, pay the price for such Product supplied by Novartis which is covered by this
subsection (v). 
 4.3 Disputed Product. If Novartis disputes a rejection of Product by Prometheus following
Prometheus’ notice to Novartis of such rejection pursuant to subsection 4.2 above, it shall so provide notice of such dispute to Prometheus (“Dispute Notice”) as soon as reasonably practicable but in any event not later than
[***] Business Days after receipt of notice of rejection from Prometheus. In such event, the disputed product will be evaluated by independent third parties (the “Disputed Product”). Depending on the nature of the dispute, the
Parties shall proceed as follows: 
 (a) For disputes where product testing is applicable, an independent laboratory which is
acceptable to both Parties will be engaged to test the Rejected Product using the test methods described in the applicable Proleukin BLA/MA, which test methods will be validated by such laboratory. If such laboratory determines that the Disputed
Product does not contain any Non-Conformity, Prometheus will pay the fees of such laboratory related to such testing and validation of testing and will promptly pay for the Disputed Product, and such Disputed Product shall constitute Product
supplied to Prometheus pursuant to this Agreement. If such laboratory finds that the Disputed Product is Non-Conforming, Novartis will pay the fees of such laboratory related to such testing and validation of testing and will promptly replace the
Disputed Product, including paying for any freight, duties, taxes and insurance charges in connection with the delivery of such new Product, and shall promptly reimburse Prometheus for the actual costs incurred by Prometheus, in shipping, insurance
premiums, duties, taxes or other 
  
 ***Certain information on this
page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 12 

 
reasonable out-of-pocket charges directly incurred in connection with the transportation and return or destruction of the affected Product. Novartis shall take responsibility for all shipment and
delivery of any Disputed Product to such independent laboratory, at Novartis’ cost, in compliance with all Applicable Law, and shall invoice Prometheus for such costs if such laboratory determines that the Disputed Product does not contain any
Non-Conformity, and for any other out-of-pocket payment made by Novartis pursuant to Sections 4.2 or 4.3. Both Parties agree to accept and be bound by the findings of such independent laboratory. 
 (b) For disputes related to a latent defect which is not readily detected by testing, a three-member arbitration body will be established
with members who are independent of both parties, and who have the scientific knowledge and expertise to review the issues in dispute. Each Party shall appoint one (1) member of the arbitration body not more than five (5) Business Days
after Prometheus’ receipt of the Dispute Notice. Afterwards, the two (2) appointed members will mutually appoint the third independent member, who will serve as President of such arbitration body. The Parties agree that the arbitration
pursuant to this subsection (b) shall be concluded not more than [***] ([***]) days after Prometheus’ receipt of the Dispute Notice, unless the actions or omissions of a Third Party cause the conclusion of such arbitration to be delayed.
The Parties further agree to accept and be bound by the findings of such arbitration body. Decision within the arbitration body will be taken by majority. If such arbitration body determines that the Disputed Product does not contain any
Non-Conformity, Prometheus will pay any fees associated with the arbitration process and will promptly pay for the Disputed Product, and such Disputed Product shall constitute Product supplied to Prometheus pursuant to this Agreement. If such
arbitration body finds that the Disputed Product is Non-Conforming, Novartis will pay any fees associated with the arbitration process and will promptly replace the Disputed Product with new Product, including paying for any freight, duties, taxes
and insurance charges in connection with the delivery of such new Product, and shall promptly reimburse Prometheus for the actual costs incurred by Prometheus, in shipping, insurance premiums, duties, taxes or other reasonable out-of-pocket charges
directly incurred in connection with the transportation and return or destruction of the affected Product. 
 4.4 Change
Management. 
 (a) For changes that are required by Applicable Law (other than an Artwork Change) including any requirement
of a Regulatory Authority, or for safety considerations exclusively applicable to the manufacture of the Products (“Required Changes”), the Parties shall cooperate in making such Required Changes promptly. If the Required Change is
required only for the Product and/or the Territory, the reasonable and documented out-of-pocket direct costs of implementing such Required Change shall be borne by Prometheus. 
 (b) If Novartis wishes to make a change that is not a Required Change (a “Discretionary Change”), including but not limited
to a change related to the manufacturing facility where the Products are currently manufactured, the Parties shall discuss such Discretionary Change and, unless Prometheus can demonstrate that the Discretionary Change will have an adverse impact on
the Product, Novartis shall be entitled to make such Discretionary Change and shall bear all the reasonable and documented out-of-pocket direct costs of its implementation.

 (c) If Prometheus wishes to make a Discretionary Change, the Parties shall discuss such
Discretionary Change and, unless Novartis has a reasonable objection (which objection shall be deemed reasonable if based on a Subcontractor’s inability or rightful denial pursuant to the Subcontractor’s contractual rights vis a vis
Novartis to make such Discretionary Change), subject to the Parties’ agreeing upon reasonable timelines and procedures for implementing such Discretionary Change, Novartis shall implement such Discretionary Change. Prometheus shall bear all the
reasonable and documented out-of-pocket direct costs incurred by Novartis or its Affiliates or Subcontractors in connection with the implementation of such Discretionary Change. Payment for such costs shall be made by Prometheus within forty-five
(45) days of receipt of an invoice therefor, together with reasonably detailed supporting documentation.

same Calendar Year. 
 5.2 Notwithstanding Section 5.1 or any other provision hereof, in no event shall Novartis be
obliged to supply the Product at a Price per Unit that is lower than the Floor Price, except where the Actual Price for any late delivered Product is subject to reduction pursuant to Section 3.5(c). 
 5.3 The initial “Standard Supply Price per Unit” of the Product supplied by Novartis to Prometheus shall be established in

setting forth on a country by country basis (i) the number of Units Sold by Prometheus, its Affiliates or Sublicensees in the Territory pursuant to the Distribution Agreement in that Calendar Year; and (ii) the actual Net Sales for such
Calendar Year, in order to determine the Actual Price per Unit for the given Calendar Year as per Section 5.1. Within thirty (30) days of receipt by Novartis of the accounting report, the Parties shall make calculation of the difference between
the Standard Supply Price per Unit and the Actual Price to be paid for the Product supplied in such Calendar Year, and the resulting difference in amount shall be invoiced by the relevant Party to the other Party within thirty (30) days of such
reconciliation.

cancel any Purchase Orders that were submitted by Prometheus, its Affiliates or Sublicensees prior to such termination. If Novartis elects to fill any such Purchase Orders, Novartis shall use Commercially Reasonable Efforts to fill any such Purchase
Orders. If Novartis elects not to fill any such Purchase Orders, Prometheus shall reimburse Novartis for the costs (including, but not limited to, raw material costs) incurred in connection with Purchase Orders that Novartis had started to
manufacture prior to the expiration or termination of this Agreement and that are canceled by Novartis pursuant to this Section 6.2(a).

 (c) Except as provided in Section 10.2(b) of the Distribution Agreement (Termination
for Novartis’ Catastrophic Breach), the termination or expiration of this Agreement for any reason will not release either Party from the obligation to pay any sum that may be owing to the other Party (whether then or thereafter due) or operate
to discharge any liability or obligation that had been incurred by either Party prior to any such termination. 
 (d) The
following Articles and Sections of this Agreement shall survive any expiration or termination of this Agreement for any reason: Section 1.1 (to the extent necessary to give effect to the Articles and Sections enumerated in this
Section 6.2(d)), Sections 4.2 and 4.3 (to the extent necessary to finally resolve issues with respect to any Rejected Product), Section 5.4 (to the extent necessary to complete any pending reconciliation) Sections 5.6, 5.7, 6.2 and

 ARTICLE VII 
 INDEMNIFICATION; INSURANCE 
 7.1
Indemnification of Prometheus. Subject to Section 10.7(f) of the Distribution Agreement, Novartis will defend, indemnify and hold harmless Prometheus and its Affiliates, directors, officers, agents, shareholders, representatives,
consultants and employees (individually, a “Prometheus Indemnified Party” and collectively, the “Prometheus Indemnified Parties”) from and against any and all Losses suffered or incurred by the Prometheus
Indemnified Parties that result from, or arise out of: 
 (a) material breach by Novartis of any obligation, covenant, warranty
or representation in this Agreement; 
 (b) any failure of Novartis, its Affiliates or their agents to comply with any
Applicable Law in connection with performing its obligations under this Agreement; 
 (c) any [***] supplied by Novartis under
this Agreement; 
 (d) any liability arising from Novartis’ [***]; 
 (e) the negligent, reckless or willful actions or omissions of Novartis or its Affiliates in performing Novartis’ obligations under
this Agreement; 
 (f) any claim that any Intellectual Property utilized in the manufacturing processes for the Products
(including, without limitation, any Manufacturing Know-How) by Novartis, its Affiliates and/or its Subcontractors (but excluding any Intellectual Property owned or Controlled by Prometheus or its Affiliates which is utilized in connection with the
labeling or packaging for the Products) infringes upon or misappropriates the Intellectual Property or proprietary rights of any Third Party. 
 except in each case to the extent that any such Loss is attributable to any matter for which Prometheus is obligated to indemnify a Novartis Indemnified Party as provided in Section 7.2 below or pursuant to the Distribution Agreement.

 7.2 Indemnification of Novartis. Prometheus will defend, indemnify and hold harmless
Novartis and its Affiliates, directors, officers, agents, shareholders, representatives, consultants and employees (individually, a “Novartis Indemnified Party,” and collectively, the “Novartis Indemnified
Parties”), from and against any and all Losses suffered or incurred by the Novartis Indemnified Parties that result from, or arise out of: 
 (a) material breach made by Prometheus of any obligation, covenant, warranty or representation in this Agreement; 
 (b) any failure of Prometheus, its Affiliates or agents to comply with any Applicable Law in connection with performing its obligations under this Agreement or the use, storage or distribution of the
Product; 
 (c) the negligent, reckless or willful actions or omissions of Prometheus or its Affiliates in performing
Prometheus’ obligations under this Agreement; 
 (d) any failure or alleged failure of the labeling of any Product to warn
prescribers or patients of the risks of using Product; 
 except in each case to the extent that any such Loss is attributable to any matter for
which Novartis is obligated to indemnify a Prometheus Indemnified Party as provided in Section 7.1 above or pursuant to the Distribution Agreement. 
 7.3 Indemnity Procedures. A Person entitled to indemnification pursuant to either Section 7.1 or Section 7.2 will hereinafter be referred to as an “Indemnitee.” A Party
obligated to indemnify an Indemnitee hereunder will hereinafter be referred to as an “Indemnitor.” In the event an Indemnitee is seeking indemnification under either Section 7.1 or Section 7.2, the Indemnitee will inform
the Indemnitor of a Claim as soon as reasonably practicable after it receives notice of the Third Party Claim, it being understood and agreed that the failure by an Indemnitee to give notice of a Third Party Claim as provided in this
Section 7.3 will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that such Indemnitor is actually and materially prejudiced as a result of such failure to give notice. The
Indemnitee will permit the Indemnitor to assume direction and control of the defense of the Claim, and, at the Indemnitor’s expense, will co-operate as reasonably requested in the defense of the Claim. The Indemnitee will have the right to
retain its own counsel at its own expense; provided, that, if the Indemnitor assumes control of such defense and the Indemnitee reasonably concludes, based on advice from counsel, that the Indemnitor and the Indemnitee have conflicting
interests with respect to such Claim, the Indemnitor will be responsible for the cost of one counsel for the Indemnitee (and all other Indemnitees in connection with the same Claim or multiple Claims arising out of the same events or circumstances).
The Indemnitor may not settle such Claim, or otherwise consent to an adverse judgment in such Claim without the Indemnitee’s prior written consent, not to be unreasonably withheld or delayed; provided that the Indemnitor shall not
require such consent with respect to the settlement of any Claim where the sole relief provided is for monetary damages that are paid in full by the Indemnitor, which would not materially diminish or limit or otherwise adversely

  

 17 

 
affect the rights, activities or financial interests of the Indemnitee, and which does not result in any finding or admission of fault by the Indemnitee. 
 7.5 No Punitive or Exemplary Damages. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY UNDER ANY CIRCUMSTANCES OR ANY LEGAL OR
EQUITABLE THEORY, WHETHER IN CONTRACT, STRICT LIABILITY OR OTHERWISE, FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, SUFFERED BY THE OTHER PARTY UNDER THIS AGREEMENT. FOR
THE AVOIDANCE OF DOUBT, ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT OR SPECIAL DAMAGES AWARDED TO A THIRD PARTY IN RELATION TO A CLAIM FOR WHICH A PARTY HAS AN INDEMNIFICATION OBLIGATION PURSUANT TO SECTION 7.1 OR SECTION 7.2 OF THIS
AGREEMENT, SHALL BE CONSIDERED DIRECT DAMAGES INCURRED BY THE INDEMNIFIED PARTY UNDER THIS AGREEMENT. 
 7.6 Insurance.
During the Term of this Agreement, each Party shall at all times maintain insurance policies or self-insurance in such amounts and with such scope of coverage as are adequate to cover such Party’s obligations under this Agreement. If requested
by the other Party, the insured Party shall furnish a Certificate of Insurance or other reasonable proof of coverage (which may be a certificate or other evidence issued by a Party under a program of self-insurance) evidencing the requisite coverage
required under this Section during the Term of the Agreement. 
 ARTICLE VIII

Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the Parties shall be
