Jerusalem, Israel (“Licensor”). Each of the Licensor and Licensee may also be identified herein as a “Party” and together as the “Parties”. 

WHEREAS, Licensor is the owner of the Existing Patents (defined below) and has the right to grant licenses thereunder; and

 (d)
Licensee shall require each Sublicensee to provide it with regular written royalty reports, which it shall provide to Licensor.

paid to Licensor in connection with a Sublicense (or option for Sublicense) of any particular Licensed Product or part of the Licensed Intellectual Property (the “Relevant Product” and “Relevant Technology”|,
respectively) will be credited against any Milestone Payments thereafter due to Licensor in respect of the Relevant Product or any Licensed Product developed with the Relevant Technology, and alternatively, any Milestone Payments paid to Licensor in
respect of any Licensed Product will be credited against any amount on account of Sublicense Fees thereafter due to Licensor in connection with a Sublicense (or option for Sublicense) of such Licensed Product or part of the Licensed Intellectual
Property with which such Licensed Product was developed.

Sublicensees from sale of Licensed Products (“Sublicense Royalties”) provided, however, that Sublicense Royalties payable to Licensor on revenues pursuant to this Paragraph 3.2(c) in relation to any particular sale of Licensed
Product by a Sublicensee shall not exceed eight point five percent (8.5%) of the payment received by the Licensee or its Affiliate from the Sublicensee in relation to such sale.

for the purchase of United States Dollars with such currency quoted by The Chase Manhattan Bank, New York, New York, on the last business day of the payment period in question shall be used. 

3.4 Taxes. For the avoidance of doubt, in calculating amounts received by Licensee, whether by way of Revenues or Sublicense Income, any amount deducted or
withheld in connection with any payment to Licensee, on account of taxes on net income (including income taxes, capital gains tax, taxes on profits or taxes of a similar nature) payable by Licensee in any jurisdiction, shall be deemed,
notwithstanding such deduction or withholding, as having been received by Licensee. 
 3.5 Deductions at Source. If Licensee is required to deduct
withholding tax at source from payments to Licensor, under applicable law, the Licensee will provide Licensor with reasonable assistance with Licensor’s efforts to claim an exemption from or reduction in any applicable tax withholdings and (if
applicable) a refund of tax withheld, or to obtain a credit with respect to the tax paid. 
 3.6 Late Payments. All payments set forth in this Agreement
shall, if not paid within thirty (30) days of the due date, bear interest at the lower of (a) the Prime Rate published in the Wall Street Journal on the due date plus 200 basis points, or (b) the maximum interest rate permitted by
law. The payment of such interest shall not foreclose Licensor from exercising any other rights it may have as a consequence of the lateness of any payment.

 ARTICLE IV: DEVELOPMENT/MARKETING EFFORTS AND DILIGENCE 

4.1 Diligence. Upon the execution of this Agreement, Licensee represents that it intends to, and warrants that it shall, using Commercially Reasonable Efforts,
proceed with the development, refinement, testing, manufacture, sale and commercialization of at least one Licensed Product, and shall, using Commercially Reasonable Efforts, endeavor to have the Licensed Product approved for marketing in the United
States and such other countries as shall be determined by and in the sole discretion of Licensee and shall use Commercially Reasonable Efforts to have Licensed Product marketed within a reasonable time after execution of this Agreement, and in
quantities sufficient to meet the market demands for them. Licensee shall use Commercially Reasonable Efforts to bring one or more Licensed Products into the commercial market as soon as practicable and to continue active marketing efforts for one
or more Licensed Products throughout the Term. 
 4.2 Marking. Licensee shall mark and have marked every Licensed Product with the patent numbers of the
Licensed Patents as appropriate under applicable law. 
 4.3 Research and Clinical Trial Work. For research to be conducted in Israel sponsored by Licensee,
Licensee will offer Licensor a right of first refusal to participate as a study site for clinical and preclinical studies, to the extent suitable based on Licensor’s capabilities (which the Parties shall discuss in good faith on an ad hoc
basis). Such offers will be contingent on Licensor successfully obtaining Good Clinical Practices (“GCP”) and Good Laboratory Practices (“GLP”) certifications (as applicable) with an appropriate regulatory body. Once Licensee
notifies Licensor of any such opportunity, and Licensor affirms in writing within fifteen (15) days that it wishes to pursue such opportunity, the Parties will negotiate in good faith for a period of sixty (60) days. If the Parties are unable
to agree on terms for such participation by Licensor as a study site during such period of time, Licensee shall be free to undertake such participation itself or through an Affiliate or engage any other person to participate in such clinical and
preclinical studies. 
 ARTICLE V: REPORTS AND RECORDS 

5.1 Books and Records. Licensee shall keep and preserve, in accordance with generally accepted accounting principles and procedures, complete and accurate
books, records and accounts containing all particulars that may be necessary for the purpose of showing the amounts payable to Licensor hereunder. Said books, records and accounts shall be kept at Licensee’s principal place of business or the
principal place of business of the appropriate division of Licensee to which this Agreement relates. Said books and supporting data shall be open, upon reasonable notice at all reasonable times and places during business hours for five (5) years
following the end of the calendar year to which they pertain, to the 

  
 8 

 Execution version 
  

 
inspection of Licensor or its agents, for the purpose of verifying Licensee’s royalty and other payment statements or compliance in other respects with this Agreement. Should such inspection
lead to the discovery of a greater than five percent (5%) discrepancy in reporting to Licensor’s detriment, Licensee agrees to reimburse Licensor for the full cost of such inspection. 

5.2 Delivery of Reports. Licensee shall, within thirty (30) days of March 31, June 30, September 30 and December 31 of each year,
beginning the first calendar quarter which commences after the Effective Date of this Agreement, deliver to Licensor true and accurate reports, giving such particulars of the business conducted by Licensee, its Affiliates and its Sublicensees during
the preceding quarterly period under this Agreement as shall be pertinent to the calculation of Royalties, Sublicensee Income/Fees and other payment accounting hereunder. 

5.3 Report Payments. With each such report submitted, Licensee shall pay to Licensor all Royalties, Sublicensee Fees, and any other payment owed, due and
payable under this Agreement, save for Milestone Payments, which are due upon each relevant milestone being met. If no payments shall be due, Licensee shall so report. 

5.4 Status and Progress Reports. Within one week of the Effective Date, the Licensee shall provide Licensor with a list of Licensed Products under development
and the status thereof (i.e. pre-clinical development or phase of clinical trials, as the case may be). Moreover, along with each payment report due on June 30 and December 31 of each year pursuant
to Paragraph 5.2, Licensee shall also submit to Licensor semiannual progress reports (“Progress Reports”) covering Licensee’s activities describing its development and testing of Licensed Products, its collaborations, joint ventures
and other commercialization efforts, occurring in each six-month period ending June 30 and December 31 during the Term beginning in calendar year 2019. Progress Reports shall be due within thirty
(30) days of the end of the preceding six-month period. Licensor shall keep such reports confidential under Article XI, to the extent reports are suitably designated as such.

6.1 IP Filing, Prosecution and Maintenance. Licensee acknowledges and agrees that Licensor shall be responsible for preparing, applying for, seeking prompt
issuance of, and maintaining the Licensed Patents during the Term. Licensor agrees to provide Licensee with copies of all patents, patent applications, patent office correspondence and all other material correspondence between Licensor and its
patent counsel relating to the Licensed Patents that it receives. Licensor shall inform Licensee of any action affecting the Licensed Patents in any manner (other than purely technical actions), so as to allow Licensee reasonable time to provide its
input to Licensor. All actions and decisions to be taken with respect to Licensed Patents, including any amended or newly presented claim language, shall be carried out cooperatively, with a view to 

  
 9 

 Execution version 
  

 
ensuring optimal patent coverage for the Licensed Products to the extent practicable, in a timely manner so as to ensure that maintenance fees are timely paid for all issued patents in Licensed
Patents, and fees are timely paid and all necessary actions timely taken so as to maintain pendency of pending patent applications in Licensed Patents. In the event of any disagreement between the Parties in relation to any action, the final
decision shall lie with Licensor. Licensee shall ensure that Prof. Daniel Javitt, as a co-inventor of the Licensed Patents, will cooperate with all required actions for pending applications (e.g., signing
inventor declarations and the like). 
 6.2 Reimbursement of Prior Patent Costs. Licensee shall reimburse Licensor for the actual costs incurred by Licensor

	7.1	 Notice of Infringement. Each Party shall promptly notify the other Party in writing of any alleged or
threatened (i) infringement of the Licensed Patents by a third party, (ii) assertion of any invalidity or unenforceability of any of the Licensed Patents by any third party, in each case in the Field in the Territory, of which such Party
becomes aware. 

  

	7.2	 To the extent permitted by applicable law, if the Licensee, its Affiliate or any Sublicensee makes (directly or
indirectly), any assertion, application or claim, or initiates or supports (directly or indirectly) any action or proceeding, that challenges the validity, enforceability or scope of any of the Licensed Patents (“Challenge
Proceeding”), Licensor will have the right, at any time following the commencement of the Challenge Proceeding, to terminate this Agreement solely with respect to the Licensed Patent(s) that are included in the Challenge Proceeding, but not
with respect to any Licensed Patent(s) that are not included in the Challenge Proceeding. If the outcome of such Challenge Proceeding is in Licensee’s favor, Licensee will have no right to recoup any Royalties or other amounts paid to Licensor
hereunder before or during the course of such Challenge Proceeding. If the determination is in favor of Licensor, Licensee shall reimburse Licensor’s entire costs and attorneys’ fees for the Challenge Proceeding, and the rates set forth in

	7.3	 Action Against Infringement. The Licensee, its Affiliate or Sublicensee shall have the first right, but not
obligation, in its own name and at its own expense to initiate any legal action and enforce the Licensed Patents against any infringement of the Licensed Patents in the Field. Before the Licensee, its Affiliate or its Sublicensee commences an action
with respect to any infringement, the Licensee shall give careful consideration in good faith to the views of Licensor in making its decision whether or not to initiate any legal action and, if relevant, make these views known to its Affiliate or
Sublicensee. The Licensee shall, or, if relevant, shall ensure that its Affiliate or Sublicensee shall, continuously keep Licensor apprised of all developments in the action and shall continuously provide Licensor with full information and copies of
all documents relevant to the proceedings, including, all documents filed with the courts by the parties to the legal action( s) and all correspondence with the other parties to the proceedings, and shall seek Licensor’s input and approval on
any substantive submissions or positions taken in the litigation regarding the scope, validity or enforceability of the Licensed Patents. 

  

	7.4	 If Licensor shall determine that the legal actions taken by Licensee pursuant to Paragraph 7.3 may adversely
affect Licensor’s rights hereunder, Licensor shall be entitled to appoint its own counsel to represent it in such litigation. If the Licensee, its Affiliate or its Sublicensee elects to commence an action as described above and Licensor is a
legally indispensable party to such action (being the registered owner of the infringed patent rights), Licensor, at the Licensee’s expense, may be joined as a co-plaintiff, provided that all the
following conditions shall be fulfilled: 

 (a) the Licensee shall promptly provide Licensor with full information and
copies of all documents relevant to the proceedings, including, all documents filed with the courts by the parties to the legal action(s) and all correspondence with the other parties to the proceedings, as well as all drafts of written submissions
relating to such legal action that are sent to the Licensee for review, and all Licensor’s comments in respect thereof will be taken into account; 

(b) any out of pocket expenses incurred by the Licensee or Licensor in connection with such action(s ), including all legal and litigation
related fees and expenses, all out of pocket expenses for external assistance required to comply with any discovery or other motions and any costs or amounts awarded to the counterparties in such action(s) shall be borne by the Licensee; 

(c) if Licensor shall determine that a conflict of interest exists between the Licensee and Licensor, Licensor shall be entitled, at its own
expense, to appoint its own counsel to represent it in such litigation and the Licensee shall make best efforts to ensure that such counsel chosen by Licensor is fully informed and receives all material necessary to adequately participate in such
action; and 

  
 11 

 Execution version 
  

 (d) the Licensee shall bear all costs, expenses and awards incurred by or awarded against
Licensor, with respect to any action filed against Licensor alleging that an action initiated by the Licensee pursuant to the terms of this Article VII was anticompetitive, malicious, or otherwise brought for an improper purpose, whether by a
counterparty to such aforementioned action or by any third party. 
  

	7.5	 If Licensor is not required by law to be joined as a co-plaintiff in
any action brought by Licensee under Paragraph 7.3, Licensor, to the extent permitted by law, and at its own cost, may elect to join the action as a co-plaintiff at its own initiative and shall jointly control
the action with Licensee, its Affiliate or its Sublicensee. Irrespective of whether Licensor joins any such action as described above it shall provide reasonable cooperation to Licensee, its Affiliate or its Sublicensee. Licensee shall reimburse
Licensor for any costs it incurs as part of an action brought pursuant to Paragraph 7.3 where Licensor has not elected to join the action as a co-plaintiff at its own initiative. 

 

	7.6	 If Licensee does not take action in the legal action and enforcement of Licensed Patents against any
infringement of the Licensed Patents in the Field pursuant to Paragraph 7.3 above, and has not commenced negotiations with the infringer for the discontinuance of said infringement, within ninety (90) days after becoming aware of such
infringement, Licensor may elect to do so. The expenses of such suit or suits that Licensor elects to bring, including any reasonable expenses of Licensee incurred in conjunction with the prosecution of such suits or the settlement thereof, shall be
paid for entirely by Licensor. Licensor shall not compromise or settle litigation in a manner that adversely impacts the rights of Licensee hereunder without the prior written consent of Licensee, which consent shall not be umeasonably withheld or
delayed. In the event Licensor exercises its right to sue pursuant to this Paragraph 7.6 it shall retain all sums recovered in such suit or in settlement thereof. 

 

	7.7	 No settlement, consent judgment or other voluntary disposition of an infringement suit may be entered by either
Party without the consent of the other Party, which consent shall not be umeasonably withheld, conditioned or delayed. 

  

	7.8	 Any award or settlement payment resulting from an action initiated by Licensee pursuant to this Article VII
shall be utilized, first to effect reimbursement of documented out-of-pocket expenses incurred by both Parties in relation to such legal action, and thereafter shall be
paid to Licensee and shall be deemed Sublicense Income received under this Agreement, in respect of which Sublicense Fees shall be due to the Licensor.

 10.2 No Waiver. Notwithstanding the foregoing, nothing in this Article X shall be construed to waive any
rights or timely performance of any obligations existing under this Agreement. 
 ARTICLE XI: CONFIDENTIALITY. PUBLICATIONS 

11.1 All information designated by either Party or its Affiliates as confidential, disclosed or made available by such Party or on its behalf or by any of its
Affiliates and their respective employees, officers, agents, contractors or consultants, or otherwise obtained or produced in connection with, relating to or arising from this Agreement, (provided that for the purpose of this section, subcontractors
and/or research partners of the Company who have executed in advance and in writing, an obligation of confidentiality, shall not be deemed third parties), whether in written, oral, electronic or any other form (respectively
“Discloser” and “Confidential Information”) shall be treated by the other Party and its Affiliates and their respective employees, service providers, consultants and assistants (each, a
“Recipient”), as confidential both during the term of this Agreement and thereafter following termination of this Agreement. For the avoidance of doubt, the Study Data shall be treated as Confidential Information of the Licensor
hereunder. The Recipient shall safeguard such Confidential Information with the same degree of care that Recipient maintains or protects its own confidential information, but in any event, no less than a reasonable degree of care. 

11.2 Recipient may not disclose any of the Discloser’s Confidential Information to any third party without prior written approval from the Discloser,
except (i) to Recipient’s employees and or associated staff involved in the performance of Recipient’s duties and obligations hereunder who have a
need-to-know, and who are bound by confidentiality and non-use undertakings similar to those contained herein; and (ii) to
the extent required by law and/or court order and/or any national regulatory authority, provided that Recipient promptly notifies the Discloser thereof in order to enable it to seek an appropriate protective order or other reliable assurance
that confidential treatment will be accorded to such information (with Recipient’s assistance, if necessary). The confidentiality restrictions shall not apply to information which the Recipient can prove was in its possession at the time of
disclosure as evidenced by its records or which is, or becomes, public domain through no fault of a Recipient or a breach of this Agreement. Confidential Information shall not be deemed to be in the public domain merely because any part of the
Confidential Information is embodied in general disclosure or because individual features, components or combinations thereof are now or become known to the public. 

11.3 Neither Party shall disclose this Agreement and the terms hereof, or use the name of the other Party or any of their respective employees or service
providers in any manner whatsoever, including marketing, advertising, press release or other promotional literature or any other publicity, without the other Party’s prior written consent, all except for any mention in any
applications to official authorities for regulatory approval (to the extent necessary), or in the 

  
 16 

 Execution version 
  

 
fulfillment of any duty owed (if any) to any competent authority. In case of an official press release or any other media publication, the Parties shall act in a manner agreed upon by the
Parties. The Licensee shall be entitled to provide a copy of this Agreement as part of a due diligence process by a potential investor or potential business partner, provided that the counterparty executes a confidentiality undertaking with
obligations and restrictions that are no less stringent than those provided herein. 
 11.4 Licensor shall have the right to publish findings relating to
the Licensed Intellectual Property in any scientific j oumals, manuscripts, book chapters or at any scientific conferences or meetings or to give oral presentations (including lectures or seminars) to third parties relating thereto. Notwithstanding
the foregoing, any such publication or disclosure shall be on the condition that, to the extent that the information to be published or disclosed is information which is not in the public domain, the said contemplated publication or disclosure shall
have been furnished to the Licensee in advance and in writing and the Licensee shall have failed to notify Licensor in writing, within thirty (30) days from receipt of the said draft publication or disclosure, that it identified non-public information that should be protected by a patent application. Should the Licensee notify Licensor pursuant to the preceding sentence that an application for a Licensed Patent application be filed
accordingly, then Licensor shall postpone such publication or disclosure until an application for a Licensed Patent is filed, or, at Licensor’s election, the relevant non-public information shall be
deleted from such publication or disclosure. 
 ARTICLE XII: TERM AND TERMINATION 

12.1 Term.

12.2 Without prejudice to the Parties’ rights pursuant to this Agreement or at law, either Party may terminate this Agreement by written notice to the
other in any of the following cases: 
  

	(a)	 immediately upon such written notice, if: (i) the other Party passes a resolution for voluntary winding up
or a winding up application is made against it and not set aside within sixty (60) days; or (ii) a receiver or liquidator is appointed for the other Party; or (iii) the other Party enters into winding up or insolvency or bankruptcy
proceedings. Each of the Parties undertakes to notify the other within seven (7) days if any of the abovementioned events occur; or 

  

	(b)	 upon breach of this Agreement, where such breach has not been remedied within sixty (60) days from the
breaching Party’s receipt of written notice from the non-breaching Party requiring such remedy. 

  
 17 

 Execution version 
  

 12.3 Upon termination of this Agreement for any reason other than the expiration of the Term, the license
granted hereunder shall terminate, the Licensed Intellectual Property and all rights included therein shall revert to Licensor and Licensee shall immediately return all physical embodiments thereof to Licensor. Licensor shall be free to enter into
agreements with any other third parties for the granting of a license to the Licensed Intellectual Property or to deal in any other manner with such right as it shall see fit at its sole discretion. 

12.4 Survival. Upon termination of this Agreement for any reason, nothing herein shall be construed to release either Party from any obligation that matured
prior to the effective date of such termination; and this Paragraph 12.4 and Articles I, VIII, IX, X, XI, and this XII shall survive any such termination. Licensee and any Sublicensee may, however, after the effective date of such termination, sell
all Licensed Products, and complete Licensed Products in the process of manufacture at the time of such termination and sell the same, within the first six ( 6) months following termination, provided that Licensee submits the reports required by
Article V hereof and pays Royalties in respect thereto as provided herein. Upon termination of this Agreement for any reason, Licensee’s obligation to make payments pursuant to Article III hereof shall terminate, except in respect of revenues
from the sale of Licensed Products received prior to the date of termination or following the date of termination, as permitted pursuant to this Paragraph 12.4, as well as any other payment that accrued prior to the date of termination of this
Agreement. 
 ARTICLE XIII: MISCELLANEOUS PROVISIONS 

13.1 Entire Agreement; Preference of Documents. This Agreement embodies the entire understanding of the Parties and shall supersede all previous
communications, representations, or undertakings, either verbal or written, between the Parties relating to the subject matter hereof. For avoidance of doubt, this Agreement supersedes and replaces the provisions of the Term Sheet, as of the
Effective Date hereof. This Agreement is a stand-alone agreement, In the event of any conflict between the provisions of this Agreement and the Term Sheet, the provisions of this Agreement shall govern. 

13.2 Amendment. This Agreement may be amended only by a written agreement embodying the full terms of the amendment signed by authorized representatives of
both Parties. 
 13.3 Severability. Should any provision of this Agreement be held to be illegal, invalid or unenforceable, by any court of competent
jurisdiction, such provision shall be modified by such court in compliance with the law and, as modified, enforced. The remaining provisions of this Agreement shall be construed in accordance with the modified provision as if such illegal, invalid
or unenforceable provision had not been contained herein. 
 13.4 No Strict Construction. The language used in this Agreement shall be deemed to be the
language chosen by both Parties hereto to express their mutual intent and no rule of strict construction against either Party shall apply to any term or condition of this Agreement. 

  
 18 

 Execution version 
  

 13.5 No Partnership, etc. Nothing contained in this Agreement shall be construed as creating a partnership,
joint venture, agency or an association of any kind between the Parties. 
 13.6 No Waiver. The failure of one Party hereto to enforce at any time any of
the provisions of this Agreement, or any rights in respect thereto, or to exercise any election herein provided, shall in no way be considered to be a waiver of such provision, rights or elections or in any way to affect the validity of this
Agreement, or excuse a similar subsequent failure to perform any such term or condition by the other Party. Any waiver must be in writing. 
 13.7
Successors Bound. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, and any corporation, partnership or other entity into or with which any Party hereto may merge,
consolidate or reorganize. 
 13.8 Assignment. Except as otherwise provided herein, no Party may transfer or assign or endorse its rights, duties or
obligations pursuant to this Agreement to another, without the prior written consent of the other Party, which consent shall not be unreasonably denied, conditioned or delayed. Notwithstanding the foregoing, Licensor may assign any or all of its
rights hereunder to an Affiliate, by written notice to Licensee. 
 13.9 Interpretation. The headings of sections or paragraphs contained herein are
inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. 
 13 .1 0
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule that would cause the application of the laws of any
jurisdiction other than the State of Delaware, except that questions affecting the construction and effect of any patent shall be determined by the law of the country in which the patent was granted. The Parties hereby accept, and agree to waive
challenge to, jurisdiction and venue in the state and federal courts located in Wilmington, Delaware. 
 13.11 Injunctive Relief. Each Party agrees that any
breach or threatened breach of the terms and conditions of this Agreement governing confidentiality or the exploitation and use of the Licensed Intellectual Property may cause irreparable harm, that may be difficult to ascertain and that monetary
damages may not afford an adequate remedy. Accordingly, in addition to all other rights and remedies that may be available to the non-breaching Party under this Agreement or by law, such Party shall be
entitled to seek, in the said courts and under the law mutually agreed to in Paragraph 13.1 0 above, injunctive relief without proof of damages.

Foundation hereby grants to Licensee an exclusive option to negotiate, in good faith, to obtain a commercial royalty bearing license with the right to sublicense, to make, have made, import, use, offer for sale and sell products and/or services,
which encompass the Foundation Subject Matter, and any Foundation patents or patent applications pertaining to Foundation Subject Matter , if any, in the Option Field throughout the Territory under mutually agreed upon terms and conditions (the
“Option”). The parties agree that the royalty rate contained in any such royalty-bearing license will be reasonable in light of the circumstances and consistent with industry standards.

	 	2.6.	 Exercise of Option 

 

	 	(a)	 Licensee may exercise the Option anytime during the Term (“Option Period”).    

  

	 	(b)	 To exercise the Option and begin a sixty (60) day negotiation period with Foundation, an authorized
representative of Licensee shall provide written notice, pursuant to Section 18.5, to Foundation of such desire. With such written notice or concurrent with such written notice if notice is by electronic mail, Licensee shall deliver to

“Negotiation Period”). 

  

	 	(d)	 During the Option Period and, if applicable, during the Negotiation Period Foundation shall refrain from
offering any commercial rights whatsoever in Foundation Subject Matter or any Foundation patents or patent applications pertaining to Foundation Subject Matter to any Third Party. However, if Licensee chooses not to exercise the Option, or if the
parties are unable to agree to terms and conditions for a royalty bearing commercial license within the Negotiation Period, the parties understand and agree that the Option shall automatically terminate and Licensee thereafter shall have no rights
whatsoever in or to Foundation Subject Matter or any Foundation patents or patent applications pertaining to Foundation Subject Matter in the Option Field. Thereupon, Foundation is free to enter into any commercial agreement, option or license
granting rights to Foundation Subject Matter or patents or patent applications pertaining to Foundation Subject Matter in the Option Field with any Third-Party on any terms and conditions.

	3.	 CONSIDERATION AND PAYMENT TERMS 

The parties hereto understand that the fees payable by Licensee to Foundation under this Agreement are partial consideration for the license and Option granted
under this Agreement. Licensee will pay Foundation: 
  

	 	3.1.	 Upfront Fee. Within thirty (30) days of the Effective Date, Licensee will pay to Foundation an
upfront, nonrefundable, non-creditable payment of fifty thousand U.S. Dollars (US$50,000.00).

	 	3.4.	 Importance of Technical Information and Material. Licensee has requested, and Foundation has agreed, to
grant certain rights to the Technical Information and Materials within the Foundation Subject Matter. Licensee desires these rights in order to develop and commercialize the Foundation Subject Matter. Because of the importance of Technical
Information and Materials, Licensee has agreed to pay certain fees to Foundation on Products or Services, as specified herein, even if it is not covered by a patent or patent application, in order to obtain rights to Technical Information and
Materials. Licensee has agreed to these payments because of the commercial value of Technical Information and Materials, separate and distinct from the existence or rights to any a patent or patent application related to the Foundation Subject
Matter, that Licensee acknowledges would provide a commercial advantage. Licensee acknowledges that it would not have entered into this Agreement without receiving the rights to the Technical Information and Materials within the Licensed Subject
Matter specified in Section 2. Licensee further acknowledges that licenses to Technical Information, Materials, and each patent and application if any are separately available to license, and that for convenience and because of the preference
of Licensee, the parties executed this combined license and option to the Foundation Subject Matter. 

  

	 	3.5.	 Payment Terms and Supporting Documentation. All dollar amounts for Payments Due referenced herein will
refer to U.S. Dollars. Payments with designated payment dates are due and payable on or before those dates. For the avoidance of doubt, Licensee is solely responsible for bank transfer charges, including but not limited to, wire transfer
fees.

will be calculated from the date payment was due until payment is actually received by Foundation, inclusive. 

  

	 	3.8.	 Foreign Charges. Royalties due for sales that occur in any country may not be reduced by any deduction
of withholding, value-added taxes, fees, or other charges imposed by the government of such country, except as permitted in the definition of Net Sales.

of its Affiliate(s) with the terms and conditions of the License. For the purposes of payments, Licensee shall be fully and solely responsible for any Payments Due to Foundation, pursuant to the terms of this Agreement, from Affiliate(s) as a result

with implementation of the Development & Commercialization Plan. 

  

	 	4.3.	 Licensee acknowledges and agrees that a fundamental purpose of this Agreement is to achieve development and
commercialization of the Foundation Subject Matter, Services and Products in the License Field throughout the Territory, and the terms in this Section 4 constitute material terms of this Agreement. If Licensee fails to perform any of its
obligations specified in this Article 4, then Foundation will have the unilateral right and option to: (i) terminate this Agreement; or (ii) modify the terms of the Agreement. This right to modify the terms, if exercised by Foundation,
supersedes the rights granted in Section 2.1 of this Agreement.

	7.	 BOOKS, RECORDS, AND REPORTS 

 

	 	7.1.	 Full and Accurate Records. Licensee will keep, and will cause its Affiliates to keep, full and accurate
books and records in sufficient detail so that Licensee’s compliance with its obligations under this Agreement can be properly determined without undue delay or difficulty. Such books and records will be maintained for at least six

returns; company financial statements; sales analysis reports; inventory and manufacturing records; distributor agreements; price lists, product catalogs, and other marketing materials; and laboratory notebooks. 

 

	 	7.2.	 Inspection of Records. Foundation may, from time to time and at any reasonable time, not exceeding once
every twelve (12) months, through an Independent Auditor as Foundation may designate, inspect the complete and unredacted books and records of Licensee, and its Affiliates, in order to verify the accuracy of any reported statement by Licensee
of Payments Due or amounts paid, or to determine compliance with any other obligation(s) of Licensee under this Agreement. Licensee agrees to cooperate fully with the Independent Auditor in connection with such review. 

After completion of any such inspection, Foundation will notify Licensee in writing of any discrepancies in Payments Due or amounts paid to
Foundation. Such inspection will be made at the expense of Foundation, unless such inspection discloses an underpayment discrepancy of five percent (5%) or more in any calendar quarter, or if such underpayment is in excess of $5,000 for any calendar
quarter or an aggregate of $10,000 for any calendar year. In such case, Licensee will be responsible for reimbursing Foundation for the inspection fee and expenses associated with such inspection within thirty (30) days after a written demand
by Foundation. Licensee agrees to pay past due amounts for any deficiency error in Payments Due as determined by the Independent Auditor, including without limitation any payment deficiency since the Effective Date of the Agreement. Any underpayment
as determined by the Independent Auditor will bear interest at one percent (1%) per month from the date the original payment was due. Foundation and the Independent Auditor will maintain in confidence such inspection and the resulting report. The
Independent Auditor may from time to time consult the Foundation and any of its employees or Third Party counsel on questions as they relate to this Agreement. The Independent Auditor may not disclose financial or proprietary information except as
required to conduct the audit, to report the results of the audit, or as otherwise permitted

	9.	 INDEMNIFICATION AND INSURANCE 

 

	 	9.1.	 Indemnification. 

 

	 	(a)	 Licensee shall indemnify, defend, and hold harmless Foundation, and its trustees, officers, staff, employees,
students, and agents and their respective successors, heirs, and assigns, and Stony Brook University, and its trustees, officers, staff, employees, students, and agents and their respective successors, heirs, and assigns, (the “Indemnified
Parties”), against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses of litigation) incurred by or imposed upon the Indemnified Parties or any one of them in connection with any claims, suits,
actions, demands, or judgments of Third Parties, Affiliates: (i) arising out of the design, production, manufacture, sale, use in commerce or in human clinical trials, lease, or promotion by Licensee or by an Affiliate, or agent of Licensee of
any Product, process or Service relating to, or developed pursuant to, this Agreement; or (ii) arising out of any other activities to be carried out by or on behalf of Licensee pursuant to this Agreement provided that the liability, damage or
loss is not attributable to the negligent activities of such Indemnified Party. 

  

	 	(b)	 Licensee agrees, at its own expense, to provide attorneys reasonably acceptable to Foundation to defend against
any actions brought or filed against any Indemnified Parties with respect to the subject of indemnity to which such Indemnified Parties are entitled hereunder, whether or not such actions are rightfully brought. Foundation will cooperate in the
defense thereof, provided, however, that Foundation will have the right, but not the obligation, to control the defense, at its expense, of any such actions. Foundation and the Indemnified Parties may, at their option and expense, have their own
counsel participate in any proceeding which is under direction of Licensee and will cooperate with Licensee and its insurer in the disposition of any such matter; provided, however, that if Licensee shall not defend such actions or if there exists
an actual or potential conflict of interest that makes representation of Indemnified Parties or Indemnified Parties and Licensee by the same counsel or the counsel selected by Licensee inappropriate, Foundation and the Indemnified Parties shall have
the right to defend such actions themselves and recover from Licensee all reasonable attorneys’ fees and expenses incurred by it during the course of such defense. 

 

	 	(c)	 Neither Foundation, the Indemnified Parties, nor Licensee shall enter into, or permit, any settlement of any
such actions without the express written consent of the other party(ies), which shall not unreasonably be withheld. 

  
 17 

	 	9.2.	 Security for Indemnification. 

 

	 	(a)	 At such time as any Product, process, or service relating to, or developed pursuant to, this Agreement, is
commercially distributed or sold, or tested in clinical trials by or on behalf of Licensee, including by its Affiliates, Licensee shall at its sole cost and expense, procure and maintain policies of comprehensive general liability insurance in
amounts not less than (i) five million U.S. Dollars ($5,000,000.00) per incident and five million U.S. Dollars ($5,000,000.00) annual aggregate during the period that such Product, process, or Service is being tested in clinical trials prior to
commercial sale, and (ii) five million U.S. Dollars ($5,000,000.00) per incident and five million U.S. Dollars ($5,000,000.00) annual aggregate during the period that such Product, process, or Service is being commercially distributed or sold,
and in each case naming the Indemnified Parties as additional insureds. Such comprehensive general liability insurance shall provide: (i) product liability coverage; and (ii) broad form contractual liability coverage for Licensee’s
indemnification obligations under Section 9.1 of this Agreement. If Licensee elects to self-insure all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate) such
self-insurance program shall include assets or reserves which have been actuarially determined for the liabilities associated with this Agreement and must be acceptable to Foundation. 

 

	 	(b)	 The minimum amounts of insurance coverage required under this Section 9.2 shall not be construed to create
a limit of Licensee’s liability with respect to its indemnification obligations under Section 9.1 of this Agreement. 

  

	 	(c)	 Licensee shall provide Foundation with written evidence of such insurance upon request of Foundation. Licensee
shall provide Foundation with written notice at least sixty (60) days prior to the cancellation, non-renewal, or material change in such insurance; if Licensee does not obtain replacement insurance
providing comparable coverage by the end of such sixty (60) day period, Foundation shall have the right to immediately terminate this Agreement period without notice or any additional waiting periods. 

 

	 	(d)	 Licensee shall maintain such comprehensive general liability insurance beyond the expiration or termination of
this Agreement during: (i) the period that any Product(s), process, or Service, relating to, or developed pursuant to, this Agreement is being commercially distributed or sold or tested in clinical trials by or for Licensee, its Affiliates, or
used by an end-user or consumer of Product; and (ii) a reasonable period after the period referred to in (i) above which in no event shall be less than fifteen (15) years. 

  
 18 

	 	(e)	 Licensee shall use reasonable efforts to promptly recover amounts due to Foundation pursuant to
Section 9.1.

terminated without any further action by Foundation. 

  

	 	10.3.	 Licensee’s Right To Terminate. Licensee may notify Foundation of their desire to terminate this
Agreement at any time by giving Foundation sixty (60) days prior written notice. The termination will take effect on the day after such sixty (60) day period has elapsed. 

 

	 	10.4.	 Accrued Obligations. Termination of this Agreement will not relieve Licensee, including its Affiliates,

becomes effective. Licensee will pay all attorneys’ fees and costs incurred by Foundation in enforcing any obligation of Licensee or accrued right of Foundation.

Materials be provided to Foundation under this Section, such transfer shall be at Licensor’s sole expense.

	1.	 SYNOPSIS 

  

			
	Name of Investigational Product:	  	RLF-100
		
	Name of Active Ingredient:	  	Aviptadil
		
	Reference Product(s):	  	Vasoactive Intestinal Polypeptide (synthetic)
		
	Title of Study:	  	RLF-100 for the Treatment of Critical COVID-19 with Respiratory Failure
		
	Phase of Development:	  	Phase 2b/3
		
	Study Site(s):	  	Multi Center: University of Miami, UC Irvine, Houston Methodist, and others
		
	Total Participant Number:	  	Primary Cohort: 144 subjects with Critical COVID-19 on mechanical ventilation, non-invasive ventilation or high flow rate nasal cannula at minimum 20L

		  	 1)  Resolution of respiratory failure by Day 10, and

		  	 2)  Alive Day 28.

		  	Key Secondary Measure:
		  	 3)  Time to resolution of respiratory failure, expect to see advantage by Day
10

		  	Secondary Outcome Measures:
		  	 4)  Respiratory Distress while on mechanical ventilation:

		  	 Blood PaO2/FiO2 ratio [Time Frame: enrollment through extubation]

		  	 5)  Oxygenation Index

		  	 6)  Improvement in chest x-ray

		  	 7)  NIAID Ordinal Scale for Clinical Improvement

		  	 8)  NIAID Area under the curve (AUC)

		  	Other Outcome Measures:
		  	 9)  Survival lifetable

		  	 10)  Time in ICU

		  	 11)  Time on mechanical ventilation

		  	 12)  Time on any ventilation

		  	 13)  Time to extubation

		  	 14)  Time to discharge alive

		  	 15)  Multi-organ failure free days

		  	 16)  IL-6, TNFα and other inflammatory
markers

  

			
	  	  	Page | 2          

 

 
  

			
	Study Design:	  	Patients with Critical COVID-19 who are receiving Maximal Standard of Care (SOC) therapy that includes non-invasive high pressure or mechanical
ventilation will be randomized to intravenous Aviptadil + Maximal SOC vs. Placebo + Maximal SOC, escalating from 50 pmol/kg/hr to 150 pmol/kg/hr.
		
	Inclusion Criteria:	  	 1)  Primary Cohort: Critical COVID-19 (test
positive in past 7 days) with respiratory failure by NIH/FDA definition requiring either mechanical ventilation, non-invasive ventilation or high flow rate nasal cannula at minimum 20L flow and 50% FIO2. No
more than 7 days of mechanical ventilation.

		  	 2)  Physician commitment to maximum Standard of Care as deemed necessary

		
	Exclusion criteria:	  	 1)  Pregnancy

		  	 2)  Age <18 years

		  	 3)  Mechanical ventilation for more than 7 days in primary cohort. Mechanical
ventilation>21 days in the exploratory cohort

		  	 4)  Mean Arterial Pressure < 65 mm Hg with use of pressor per ICU
protocol

		  	 5)  Irreversible condition (other than
COVID-19) with projected fatal course

		  	 6)  ECMO

		  	 7)  Current or recent (within 30 d) enrollment in another investigational trial of anti-IL6 drug or immunomodulator drug;

		  	 8)  Active diagnosis of Acquired immune deficiency syndrome;

		  	 9)  Transplant patients currently immunosuppressed;

		  	 10)  Chemotherapy-induced neutropenia (granulocyte count <1000/mm3);

		  	 11)  Cardiogenic shock; congestive heart failure – NYHA Class 3 or
4;

		  	 12)  Recent myocardial infarction – within last 6 months and troponin >
0.5

		  	 13)  Anuria (urine output < 50 ml/d) or other signs of multi-organ
failure

		  	 14)  Severe liver disease with portal hypertension or bilirubin 4.0 or
higher;

		  	 15)  Recent stroke or head trauma within last 12 months

		  	 16)  Increased intracranial pressure, or other serious neurologic
disorder;

		  	 17)  Liquid Diarrhea more than 3x/day; defined as more than 3 non-bloody watery stools within a 24-hour period, requiring additional fluid and electrolyte supplementation

		
	Safety Assessments:	  	A safety analysis was conducted by the Data Monitoring Committee at 30 patients. All patients will be surveilled for Serious Adverse Events (SAE). All SAEs will be reported to independent Data Safety Monitoring Board and to
FDA
		
	Dosage, Route of Administration, and Schedule:	  	Three escalating doses of RLF-100 (Aviptadil): 50, 100, and 150 pmol/kg/hour or placebo administered over 12 hours via IV infusion on successive days. If side effects cannot be managed with
ICU protocol, dose reduced or halted.
		
	Statistical Methods:	  	Primary endpoint (composite) will be displayed by a 2x2 table and analyzed using a logistic regression analysis containing 4 pre-defined baseline covariates and randomized treatment group
(primary) and a two-sided chi square test (secondary). Time to event outcomes will be displayed by a Kaplan Meier lifetable and analyzed by a two-sided log rank test.
Ordinal and continuous outcomes will be assessed by mixed model repeated measures through Day 28. Maximal signal is expected by Day 10. The primary analysis will be based on the modified intent-to-treat (mITT) population.
		
	Sample Size Calculation:	  	Assuming a 25% success percent in the placebo group and a 50% success percent in the RLF-100 group, for a chi square test with two-sided 5% Type 1 error
and 80% power, the sample size to detect a 25% absolute improvement in the composite endpoint (from 25% to 50%) is 144 subjects in the primary analysis group (2:1 randomization favoring the RLF-100 group). A
25% absolute improvement is the composite success percent (25% to 50%) is deemed to be clinically meaningful.

  

			
	  	  	Page | 3          

 

 
  

			
	Interim Analyses	  	An interim look for safety and futility will be conducted once the first 30 randomized subjects complete Day 7. A second interim look for safety, futility, and efficacy will be conducted once 81 subjects complete Day 28. An α
spend is incorporated into the projected sample size to account for the two looks.
		
	Maintenance of Study Blind	  	Investigational drug will be administered in identical infusion bags, labeled by the hospital research pharmacist who is the only unblinded member of the study site. ICU personnel are entirely masked as to treatment assignment, as
are patients. Even in the event of unintentional unblinding because of differential efficacy or safety of the investigational medicinal products (drug and placebo), the randomization scheme prevents staff from knowing the next treatment assignment.
Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff.

	6.	 INTRODUCTION 

  

	6.1	 Executive Summary 

RLF-100 (aviptadil) is a synthetic form of Vasoactive Intestinal Polypeptide (VIP), a ubiquitous,
naturally synthesized human peptide with extensively documented anti-inflammatory, anti-cytokine cascade properties. Prior sponsors have been granted investigational new drug (IND) status by the US FDA and the EMEA for the use of aviptadil in Acute
Respiratory Distress Syndrome (ARDS), Acute Lung Injury (ALI), Pulmonary Fibrosis, and Sarcoidosis. In conjunction with phentolamine, intracavernous aviptadil (InvicorpTM) has been marketed in
Europe for 20 years by Evolan SE for the treatment of erectile dysfunction (ED) with no record of serious adverse events (SAE). At least five well-controlled studies have been conducted for the use of aviptadil in chronic lung conditions. RLF-100 is known to have potent anti-cytokine activity in numerous non-clinical models of ARDS and ALI and has shown early evidence of efficacy in preserving life in patients
with ARDS. A phase 1 safety trial of aviptadil was conducted in eight patients with sepsis-related ARDS, who had an expected 50% mortality rate. Seven patients demonstrated clinical benefit based on improved blood oxygenation and were successfully
withdrawn from advanced life support. Six of those patients survived long term and left the hospital, with one succumbing to an unrelated myocardial infarction at week 3. These results demonstrate in a small sample size that aviptadil significantly
reduced expected mortality in patients with ARDS (mortality reduction of p<.01 vs historical controls). We propose RLF-100 (aviptadil) for the treatment of Critical
COVID-19. 
  

	6.2	 Definition of Critical COVID-19 

In May 2020, FDA defined Critical COVID-19 to be used in clinical trials and disease staging as
follows: 
  

			
	 Critical
 COVID-19
	  	 •   Positive testing by standard
RT-PCR assay or an equivalent test
  

	  	 •   Evidence of critical illness, defined by at least one of the
following:
  

	  	 •   Respiratory Failure defined on resource utilization requiring at least
one of the following:
  

	  	 •   Endotracheal intubation and mechanical ventilation, oxygen delivered by
high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates > 20 L/min with fraction of delivered oxygen 3 0.5), noninvasive positive pressure ventilation,
ECMO, or clinical diagnosis of respiratory failure (i.e., clinical need for one of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation)

 

	  	 •   Shock (defined by systolic blood pressure <90 mmHg, or diastolic blood
pressure <60 mmHg or requiring vasopressors)
  

	  	 •   Multi-organ dysfunction/failure

 Note that treatment with ECMO, mean arterial pressure <65 mmHg on pressors, and Multi-organ failure are
exclusion criteria for this protocol 
 Acute Lung Injury in COVID-19 is characterized by progressive
failure of corporeal oxygenation, attributed on large part by SARS-CoV-2 infection of Alveolar Type II cells (Mason 2020). Extensive nonclinical studies document that
70% of VIP in the body binds to receptors on the Alveolar Type II cell, where VIP is known to block cytokine production and upregulate production of surfactant. 

Severity of COVID is associated with and graded by a progressively worsened state of oxygenation. This is seen in the PaO2/FIO2 ratio, which reflects the status of oxygenation for patients on high pressure oxygen and mechanical ventilation. In patients breathing
room air, disease severity is assessed by SpO2. Many patients with Critical COVID meet the clinical definitions of Acute Respiratory Distress Syndrome (ARDS). However, there is increasing
recognition that respiratory distress in COVID-19 has different characteristics than ARDS in the setting of bacterial sepsis and other common presentations of ARDS. 

The pathologic hallmark of COVID-19 lung injury is diffuse alveolar damage, vascular endothelium
damage, and damage to the surfactant-producing type II cells which results in loss of the integrity of the alveolar-capillary barrier, transudation of protein-rich fluid across the barrier, pulmonary edema, and hypoxemia from intrapulmonary
shunting. Typically, patients who have progressed to Critical COVID-19 require care in an intensive care unit (ICU). The mortality rate is approximately 50%. Deaths usually result from multisystem organ
failure rather than lung failure alone.

	6.3	 RLF-100 Experimental Therapy in
COVID-19 

 Under this protocol, patients with Critical COVID-19 will be randomly allocated to intravenous RLF-100, Aviptadil, with the aim to support pulmonary alveolar function, combat the cytokine-induced inflammation, improve
blood oxygenation, and reduce mortality. 
  

	6.4	 Aviptadil Background 

Aviptadil (vasoactive intestinal peptide; VIP) is an abundant biologically active peptide endogenous in humans as well as in other species. It
is produced by neurons in the peripheral and central nervous system, by endocrine cells such as pituitary lactotrophs, cells of the endocrine pancreas as well as T-lymphocytes, and B-lymphocytes. This natural peptide is one of the signal molecules of the neuroendocrine-immune network comprising vasodilation, anti-proliferative, anti-inflammatory, and immuno-suppressive features. Aviptadil is
predominantly localized in the lungs and a vast body of experimental, pharmacological as well as clinical evidence suggests Aviptadil to be an attractive candidate as a treatment option for acute pulmonary disorders. 

Endogenous aviptadil is synthesized from a precursor molecule which contains 170 amino acids and is processed to its biologically active form
via a signal peptidase in the endoplasmic reticulum and finally cleaved by prohormone convertases and by carboxypeptidase-B like enzymes to functional Aviptadil comprising the following 28 amino acids: His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-
 Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn. 

Aviptadil was first identified in the intestine and then in the central and peripheral nervous systems and has since been recognized as a
widely distributed neuropeptide, acting as a neurotransmitter and neuromodulator in many organs and tissues, including heart, lung, thyroid gland, kidney, immune system, urinary tract and genitals. 

The widespread distribution of aviptadil is correlated with its involvement in a wide variety of physiological activities including smooth
muscle relaxation, increased cardiac output, bronchodilation, immune-modulation, inhibition of smooth muscle cell proliferation, anti-apoptosis, neurotropic effects, and some differential effects on secretory processes in the gastrointestinal tract
and gastric motility. 
 The rationale for the current application can be summarized as follows: aviptadil attenuates, delays or prevents ALI
in various experimental models of ARDS, both in isolated lungs as well as in vivo. Aviptadil protects the heart and other vital organs against oxidative injury and has anti-inflammatory activity against a variety of inflammatory mediators and is
anti-apoptotic. 
  

	6.5	 Clinical Rationale 

Given by intravenous infusion in appropriate concentrations, aviptadil has been shown in clinical trials to have a manageable safety profile
with no observed SAEs to date that would rise to the level of a black box warning. 
  

	7.	 OBJECTIVES 

  

	7.1	 Primary Objective 

The primary objective of this study is to test the hypothesis that RLF-100 + maximal standard of care
(SOC) improves survival and resolves respiratory failure (see Section 6.2) in patients with Critical COVID-19 compared to those treated with placebo + maximal SOC, in both cases not including ECMO. 

  

			
	  	  	Page | 11          

 

 
  

	7.2	 Secondary Objective 

The key secondary objective is to test the hypothesis that RLF-100 decreases respiratory failure as
defined by the FDA May 2020 respiratory failure definition (see Section 6.2). 
  

	8.	 STUDY DESIGN 

  

	8.1	 Overview 

This study, RLF100-001, is a multi-center, randomized double-blind, placebo-controlled phase 2 trial,
comparing RLF-100 + Maximal SOC to placebo + Maximal SOC. Aviptadil or placebo will be administered as a 12-hour IV infusion one thee consecutive days. Primary endpoints
will be measured at ten (10) days post infusion with 28 days of follow-up. Patients with Critical COVID-19 infection will be screened. Informed consent will be
obtained from the patient or a responsible party. Once entered into the study, participants will be randomized in a 2:1 ratio of IV RLF-100 + maximal SOC vs. placebo + maximal SOC. Once enrolled, patients
assigned to receive RLF-100 will be given in three (3) doses of i.v. infusion, each dose given over 12-hour period at the same time on consecutive days, in
escalating doses from 50pmol/kg/hr to 150 pmol/kg/hr of RLF-100. The primary outcome to be measured following RLF-100 infusion is the composite endpoint of “free of
respiratory failure at 10 days and alive at 28 days.”. The declared secondary outcome to be measured following RLF-100 infusion will be Time to resolution of respiratory failure. Respiratory failure is
defined as resource-based according to the FDA May 2020 respiratory failure definition (see Section 6.2). Thirteen other efficacy endpoints are also to be evaluated in support of multi-dimensional efficacy. 

 

	8.2	 Design 

Randomized, prospective, double-blind, placebo-controlled trial of RLF-100 + maximal SOC vs. Placebo +
maximal SOC therapy in patients with Critical COVID-19. 
 Following informed consent, patients will
be randomized and administered either placebo or escalating doses of RLF-100 from 50 pmol/kg/hour IV to 150 pmol/kg/hour as three (3) 12 hour infusions each at the same time of day on subsequent study days 1,
2, and 3. Vital signs and telemetry will be monitored throughout the infusion and for 48 hours after completion of all 3 infusions.. Pulmonary, cardiovascular, hepatic, CNS, renal, and coagulation functions will be assessed daily for 5 days, and
plasma levels of aviptadil and selected cytokines will be measured. 
 The primary efficacy outcome is a
pre-defined composite success endpoint based on milestones achieved during the 28-day follow-up; the secondary outcomes will
include oxygenation levels and severity of organ dysfunction as well as other hospital-based outcome measures. 
 The composite endpoint is
defined as follows and requires both of the following success criteria to be met: 
  

	 	•	 	 Resolution of respiratory failure (no mechanical or non-mechanical
ventilation or high-flow nasal O2) by Day 10, and 

  

	 	•	 	 Alive Day 28. 

The endpoint rationale is to include the FDA required 28-day
all-cause survival outcome plus a resolution of respiratory failure (no mechanical or non-mechanical ventilation or high-flow nasal O2) by Day 10, indicative of respiratory recovery. 
  

	8.3	 Number of Participants 

Initially, randomization will result in 14 participants to receive RLF-100 + SOC and 7 participants to
receive placebo + SOC in the primary efficacy cohort comprised of patients who meet enrollment criteria and have been on mechanical ventilation for <8 days (including zero days for those not on mechanical ventilation). The total number of
participants may expand to 165 patients (110 drug/55 placebo) if there are acceptable efficacy and safety profiles at the interim analyses. The analysis at 21 patients will be 

  

			
	  	  	Page | 12          

 

 
  

 
unblinded so this cohort will not be part of the final analysis but will be included in a supportive analysis since results remain confidential. Thus, the sample size for analysis purposes well
be 144 patients for the primary analysis and 165 patients for the supportive analysis.

	8.5	 RLF-100 Treatment Protocol 

Figure 2 shows a graphical flow chart of the RLF100-001 protocol study design. 

Note: If a determination is made to slow down the infusion rate by 50% - the next infusion would still be applied at the next 24-hour period. (E.g. if infusion was started at 8:00 AM and it runs for 18 hours, the next infusion should still take place at 8:00 AM the following day.) If infusion is halted, patient remains in the study.
Physician can dose next day at last well-tolerated dose for a maximum of 3 doses. 
  

	8.6	 Anticipated Risk 

Reported adverse events for intravenous aviptadil include hypotension, tachycardia, facial flushing and watery diarrhea. If this were to
develop, the infusion would be slowed or stopped until resolved. See Flow Chart (Figure 2 above). 
  

	9.	 SELECTION OF SUBJECTS 

 

	9.1	 Study Population

	  	  	Page | 14          

 

 
  

	9.2	 Inclusion Criteria 

All patients entered this trial will have the diagnosis of Critical COVID-19. Subjects will be observed for a 1 to 24-hour period, during which

	10.	 RECRUITMENT, CONSENT & ENROLLMENT 

 

	10.1	 Recruitment & Consent Procedures 

All admissions to the intensive care unit will be screened for fulfillment of inclusion criteria by the Principal Investigator. Patients are
inherently unable to give consent in this setting. The PI or PI’s designee will seek consent from the patient’s responsible party, after explaining the procedure and consent form, approved by all participating sites. It should be noted
that one feature of the COVID-19 pandemic is that non-patients are barred from hospital premises. Therefore, informed consent from responsible parties will generally be obtained telephonically and signature will be obtained via an SMS text message
or otherwise compliant consent systems (e.g. REDCAP). Consent will be documented by a witnessed, consent form, to be kept on file together with telephonic signature. This does not preclude a site from obtaining consent via paper, if such
arrangements can be made, e.g. fax. Should the patient regain ability to consent, consent will be sought accordingly. 
  

	10.2	 Obtaining Informed Consent 

IRB-approved written informed consent forms (ICF) will be obtained from the responsible party of all subjects before any protocol-specified
procedures are carried out. For entry into the study, all inclusion criteria must be met, and none of the exclusion criteria can be met. All signed ICF forms will be logged and kept in locked research cabinets or other restricted electronic system
under the supervision of the local Site PI and available for audit upon request. 

  

			
	  	  	Page | 15          

 

 
  

	10.3	 Protecting Confidentiality 

Any information obtained in this study will be treated as confidential and will be safeguarded. The data will be coded and kept in a secure
location. When published, the results of the study will be in a form that does not identify any of the patients. In compliance with federal regulations, the records of the study will be available to representatives of the Food and Drug
Administration. 
  

	10.4	 HIPAA Compliance 

The study will be compliant with the Health Insurance Portability and Accountability Act (HIPAA), which protects the privacy and security of
healthcare information. All personal identifying information (PII) will be securely stored and only accessible to healthcare providers and authorized personnel only. 
  

	10.5	 Standard of Care Support 

Supportive treatment in the ICU, including antibiotics, oxygen, mechanical ventilation, blood pressure-supporting medications, and all other
standard of care interventions as needed, will be continued, regardless of participation in the study. 
  

	10.6	 Population Bias 

For unknown reasons, males are affected by severe COVID-19 symptoms twice (2X) as often as are females. It is likely that the enrollment in
this trial will be consistent with that gender difference. There is no evidence to suggest that RLF-100 will be differently tolerated based on race. 
  

	10.7	 Enrollment 

The total number of participants in the primary cohort (mechanical ventilation at enrollment <8 days) will be 144 patients (96 drug/48
placebo). A safety analysis will be conducted by the independent DSMB based on unblinded, unmasked data upon completion of 7-day data collection in 30 patients. DSMB meeting minutes will be recorded and provided to FDA. If the decision is made to
continue the study beyond 30 patients, the next interim analysis will be performed once 81 subjects complete the Day 28 evaluation for a safety and futility determination. Based on the results of this second determination, the study may continue
enrollment to 144 subjects. 
 An additional exploratory cohort of 30 patients (20 drug/10 placebo) will be enrolled at selected study sites
to include patients who have had between 8 – 21 days of exposure to mechanical ventilation. The DSMB will perform an efficacy and futility analysis when approximately 81 patients have completed 28 days of follow up. 

If the two-sided p-value at the time of the interim analysis is
0.01 in favor of efficacy, then the study will stop for superiority. If the conditional power, under the alternative hypothesis is less than 10%, then the study will stop for futility.

 , where t = 81/144 and p is the current one-sided p-value. The one-sided p-value to stop if the interim analysis occurs at exactly 81 patients will be 0.5949. This stop is non-binding and the DSMB will have the ability to continue if they see a
positive signal in a secondary endpoint. The final p-value for efficacy will be adjusting to account for the efficacy evaluation, using the method of Schoenfeld. If the analysis occurs at exactly 81 patients,
that two-sided p-value would be 0.045955. 
 The sample size
calculation (See Section 12.2 below) of 144 subjects (2:1 allocation favoring the RLF-100 group) is required to detect a 25% absolute increase in the composite success percent for the RLF-100 group (assuming 50% success) and the Standard of
Care Group (assuming 25% success) with 83% power and two-sided 5% Type 1 error accounting for the group sequential design using the Schoenfeld method.

	10.8	 Randomization Procedures 

Randomization will be on a 2:1 basis with a random block size of 3 or 6; in the event of multiple sites, a centralized randomization will be
used. Subjects will be stratified according to RDR (<200 mmHg, >200 mmHg) and previous anti-viral therapy for COVID-19 (none, any). 

Using this method, even if site personnel believe they can tell the difference between clinical reaction to RLF-100 vs. placebo, they have no
possibility to guess what the next allocation will be. 
  

	10.9	 Procedure for Maintaining the Blind 

Investigational drug will be delivered in identical infusion syringes, labeled by the hospital research pharmacist who is the only unblinded
member of the study site. ICU personnel are entirely blinded, as are patients. Even in the event of unintentional unblinding because of differential efficacy of drug and placebo, the randomization scheme prevents staff from knowing the next
treatment assignment. Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff. 
  

	11.	 TREATMENT OF SUBJECTS 

 

	11.1	 Maximal Standard of Care 

All patients entered in the trial receive Maximal Standard of Care treatment and support, including fluids, antibiotics, vasoactive agents,
non-invasive or mechanical ventilation, hemodialysis, surgery and other supportive measures, as indicated, except for extra-corporeal membrane oxygenation (ECMO). The need for ECMO will be considered a treatment failure on the basis that the lung
has been deemed incapable of supporting adequate metabolic function. Decisions regarding the use of intravenous fluids, cardiovascular and respiratory support, and surgical intervention are made by each patient’s attending physician and are not
dictated by the study protocol. At the completion of the three 12-hour infusions, patients are followed up for the 28 days or until discharged from the hospital, whichever comes sooner. An attempt will be made to follow all patients for 28 days even
after discharge, but it will not be practical during the Corona Pandemic either to bring patients back for post-discharge visits or to make home visits. Death while on life support vs. death following discharge from mechanical ventilation will be
tracked separately. Discharge from mechanical ventilation means that the treating physicians have deemed the patient capable of breathing without the need for mechanical ventilation. A death that occurs because life support has been withdrawn in the
absence of this determination will be recorded as death while on life support. 
  

	11.2	 Proper Standard of Care (SOC) Management Principles 

Management principles are similar despite different etiologies. Oxygenation must be maintained, and the underlying cause of acute lung injury
corrected. Meticulous attention is necessary to prevent nutritional depletion, O2 toxicity, superinfection, barotrauma, and renal failure, which may be worsened by intravascular volume depletion. While the diagnosis is being considered,
life-threatening hypoxemia must be treated with a high FiO2 and monitored with repeated arterial blood gases or noninvasive oximetry. Prompt endotracheal intubation with mechanical ventilation and PEEP may be needed to deliver O2 if hypoxemia is
refractory to O2 inhalation by face mask or nasal cannula. Despite the presence of alveolar edema, IV fluids should be given if needed to restore peripheral perfusion, urine output, and BP. Monitoring vascular volume is crucial because both
hypovolemia and overhydration are deleterious. Physical findings and central venous pressure may be misleading in critically ill patients undergoing mechanical ventilation, and if severe hypoxemia persists, if skin perfusion is poor, if mentation is
impaired, or if urinary output decreases (< 0.5 mL/kg/h), a reliable index of intravascular volume is needed immediately. 
 ECMO is a
lifesaving modality that may be used when mechanical ventilation is unable to support life. However, the availability of ECMO is limited and decisions to allocate ECMO resources to patients are likely to be based on broader triage concerns.
Therefore, ECMO is not considered part of SOC for the purposes of this study and the decision to escalate care to ECMO will be considered a treatment failure for the purpose of this study on the grounds that it signifies a determination that the
lung is unable to support life even with mechanical ventilation. 

  

			
	  	  	Page | 17          

 

 
  

	11.3	 Placebo 

A normal saline placebo will be supplied by the hospital pharmacy in a labeled container indistinguishable from active drug. 

 

	11.4	 Dosing Regimen 

The escalating dosing regimen for RLF-100 is shown in Figure 2. Each infusion is planned for 12 hours duration, however, the infusion (either
drug or placebo) may be slowed by up to 50% (for an 18-hour total infusion time) at the discretion of the site personnel if side effects cannot be managed to a clinically-acceptable level by the institution’s ICU protocol or SOC. Monitoring of
vital signs and other safety measurements will be ongoing and decisions relating to dose-reduction or cessation will be based on the evaluation of these parameters. 
  

	11.5	 Potential Side Effects of Drug Therapy 

Signs and symptoms to look for: facial flushing, tachycardia, hypotension, diarrhea. These will be monitored for the duration of the infusion,
and for 12 h afterward, by blood pressure and heart telemetry measurements and patient observation. One identified side-effect of Aviptadil infusion is watery diarrhea. As noted above, non-bloody watery diarrhea > 3x/day requiring additional
fluids and electrolyte supplementation is an enrollment exclusion. If watery diarrhea is observed during infusion, the infusion rate should be first reduced by 50% to relieve symptoms. If symptoms persist cease IV infusion. 

 

	12.	 ASSESSMENT OF SAFETY 

 

	12.1	 Serious Adverse Events 

Measurement of serious adverse events (SAE) will be the basis for assessing safety of RLF-100. All SAE’s will be recoded on an IRB
approved SAE Report Form. The SAE Report Form will include the exact nature of the event and the circumstances of the subject at the time of the event, in addition to the usual information required to document AEs or SAEs. Data on all the above will
be collected on separate eCRF pages. The latest version of the AE dictionary, MedDRA, will be used for the classification and analysis of AEs entered in the study database. For regulatory reporting, SAEs will be coded using MedDRA. 

 

	12.2	 Definition of Adverse Events 

An adverse event (AE) is any untoward medical occurrence in a clinical study subject administered a medicinal (investigational or
non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the
use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. (Definition per ICH). AEs will be classified as drug-related, possibly drug-related, or
non-drug related by the study safety monitor. 
  

	12.3	 Definition of a Serious Adverse Event 

The following criteria define a Serious Adverse Event: 
  

	 	1)	 Death 

  

	 	2)	 Life-threatening event 

 

	 	3)	 Persistent or significant disability/incapacity 

If a serious and unexpected AE occurs for which there is evidence suggesting a causal relationship between the study drug and the event (e.g.,
death from anaphylaxis), the event must be reported as a serious and unexpected suspected adverse reaction even if it is a component of the study endpoint (e.g., all-cause mortality). In addition, the following variables will be collected for SAEs:

  

	 	•	 	 Date AE met criteria for SAE 

  

			
	  	  	Page | 18          

 

 
  

	 	•	 	 Date investigator became aware of SAE 

 

	 	•	 	 Explanation of seriousness of this AE 

 

	 	•	 	 Date of hospitalization 

 

	 	•	 	 Date of discharge 

  

	 	•	 	 Probable cause of death 

 

	 	•	 	 Date of death 

  

	 	•	 	 Autopsy performed 

  

	 	•	 	 Causality assessment in relation to study procedure(s) 

 

	 	•	 	 Causality assessment in relation to study drug 

 

	 	•	 	 Causality assessment in relation to other medication 

 

	 	•	 	 Description of AE 

  

	12.4	 Relationship to Study Drugs 

Adverse events and SAEs will be collected from the time of signature of informed consent throughout the treatment period. The investigator will
assess the causal relationship (i.e., the relationship to study treatment) between the investigational product and the AEs and answer “yes” or “no” to the question “Do you consider that there is a reasonable possibility that
the event may have been caused by the investigational product?”. For SAEs, causal relationship will also be assessed. 
  

	12.5	 Recording of Adverse Events 

Abnormal and clinically significant lab values will be reported as AEs if they fulfill any of the SAE criteria or are the reason for
discontinuation of treatment with the study drug. The principal investigator and the study biostatistician will establish the rules for what will constitute abnormal and clinically significant lab values based on established site-specific lab normal
ranges. Adverse events, including abnormal lab values (clinically significant and clinically non-significant), will be review monthly for trends by the principal investigator and the medical monitor. Should any abnormal lab values exceed acceptable
rates, the FDA will be notified within regulatory timelines. Wherever possible, the reporting investigator will use the clinical, rather than the laboratory term (e.g., anemia versus low hemoglobin value). 

 

	12.6	 Reporting of Adverse Events 

All relevant AEs and special reporting situations, whether serious or non-serious, will be reported from the time a signed and dated Informed
Consent Form (ICF) is obtained until completion of the subject’s last study-related procedure. All events that meet the definition of a SAE will be reported as SAEs, regardless of whether they are protocol-specific assessments. All AEs,
regardless of seriousness, severity, or presumed relationship to study drug, must be recorded using medical terminology in the source document and the eCRF. Whenever possible, diagnoses will be given when signs and symptoms are due to a common
etiology. The sponsor assumes responsibility for appropriate reporting of AEs to the regulatory authorities. 
  

	12.7	 Reporting of Serious Adverse Events 

Reportable SAEs will be sent to the FDA by the sponsor. When a SAE is discovered, it will be reported immediately (within 24 business hours) to
the Medical Monitor. Serious adverse events will be reported within 24 business hours of the site’s knowledge of the event to the IRB, Sponsor, Medical Monitor, and study site investigators. 

 

	13.	 ASSESSMENT OF EFFICACY 

 

	13.1	 Data Collection 

Data will be collected via the electronic medical record (EMR) or other hospital information system and ICU telemetry systems. Once collected,
data will be transferred by study personnel to the Target Health 

  

			
	  	  	Page | 19          

 

 
  

 electronic data capture system, which has been audited by FDA in connection with multiple
drug approvals. GCP will be observed throughout, using the quality system in place at Target Health, LLC. Extensive data not already defined in this protocol will be available for analysis via the EMR and telemetry systems. 

 

	13.2	 Maintenance of Blinding 

Investigational drug will be delivered in infusion syringes, labeled by the hospital research pharmacist who is the only unblinded member of
the study site. ICU personnel are entirely masked as to treatment assignment, as are patients. Even in the event of unintentional blinding because of differential efficacy of drug and placebo, the randomization scheme prevents staff from knowing the
next treatment assignment. Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff. 
  

	13.3	 Primary Efficacy Endpoint 

The composite primary endpoint is consistent with the original stated objective of the study and informed by recent FDA input (Reference ID:
4613030 NeuroRx, Inc.) in which FDA recommended proportion of patients alive and free of respiratory failure at day 28. The endpoint is further informed by recent FDA guidance not released at the time of study inception.1 
  

	 	•	 	 Component 1: Resolution of respiratory failure by Day 10, and 

 

	 	•	 	 Component 2: Alive at Day 28 

The best estimate for the composite endpoint success rate is 50% for the drug group and 25% for the placebo group. This preserves the
hypotheses numbers to be tested relative to the original protocol. 
  

	13.4	 Key Secondary Endpoint 

In the findings of the study’s Data Monitoring committee held July 14, 2020, the DMC counseled the use of a primary endpoint that would
measure the difference in area under the curve, thereby using “all the data” available to establish a difference between drug and placebo. Sponsor explained Division’s preference for fixed endpoints and DMC suggested that the
lifetable analysis of time to resolution of respiratory failure be included as a key secondary endpoint. 
  

	13.5	 Assessments of Endpoints 

Composite Endpoint 
 The composite endpoint requires each
of the following to be met: 
  

	 	•	 	 Resolution of respiratory failure (no mechanical or non-mechanical ventilation or high-flow nasal O2) by Day 10.

  

	 	•	 	 Alive Day 28: Patient death is defined as asystole. Data will be collected on whether the death occurred after
withdrawal of care and, if so, the reason for withdrawal of care. Patient death is most likely to occur where the patient was hospitalized. Data will be collected on whether the death occurred after withdrawal of care and, if so, the care withdrawal
reason. 

 Index of Respiratory Distress 

The PaO2/FiO2 ratio shall be calculated from the continual telemetry data obtained from the ICU information system and arterial blood gas (ABG) for patients
while on mechanical ventilation. This variable is not useful after O2 on mechanical ventilation has been reduced because the ratio is reduced even though oxygenation is already improving. In the absence of an arterial line, ABG’s will be
collected only when medically indicated.

	  	  	Page | 20          

 

 
  

 Oxygenation Index 

The Oxygenation index is defined as: 
  

 
 

 
 Inflammatory Markers 

TNFα and other cytokine studies will be performed by the central lab. Note that these are not declared efficacy or safety endpoints 

NIAID 8-point scale 
 The NIAID 8-point scale will be used
as a measure of recovery from Critical COVID-19. 
 Improvement in Chest x-ray 

Chest x-ray images will be collected (1) pre-treatment, (2) 48-96 hours post start of infusion, (3) 1 week ±2 days post start of infusion, and
(4) two weeks ± 2 days post start of infusion, provided the patient is still hospitalized. All x-rays will be read by a blinded radiologist panel and scored according to the Rapid Assessment of Lung Edema (RALE) score (Warren 2017). 

Clinical decision to terminate mechanical ventilation 

Study research personnel will collect all available data regarding the clinical decision-making that guides removal mechanical ventilation in relation to
clinical deterioration or lack of clinical response (e.g. change in status to comfort measures, poor prognosis for recovery, allocation of resources in a pandemic setting, etc.). 

Additional data to be collected 
 Because of the unique
nature of this study and the circumstances under which it is being conducted, at FDA’s request, sponsor will collect all data regarding the use of experimental therapeutic agents (e.g. hydroxychloroquine, IL-6 inhibitors, and other topics of
interest) and deliver those data to FDA for further analysis. Sponsor will make this analysis data set available to the broader scientific community as well. NIAID Scores will also be collected daily through hospital discharge and weekly through Day
28. In addition, time to resolution of respiratory failure, time in ICU, time on mechanical ventilation, time to extubation, time to discharge, multi-organ failure-free days, and inflammatory markers will be collected. 

 

	14.	 STATISTICAL ANALYSIS 

 

	14.1	 Statistical Design and Analyses 

All analyses will be pre-specified in a Statistical Analysis Plan to be finalized with FDA prior to database lock. 

A group sequential design will be employed with one interim analyses for futility and efficacy (n=81). An unblinded analysis will also occur 21
patients for possible study redesign. These 21 patients will not be part of the primary analysis but will be included in a confirmatory analysis since their data were kept confidential. 

All calculations will be performed using SAS statistical software, version 9.3 or later, and StatXact, version 10 or later. All efficacy and
safety data will be displayed in tables and listings separately for each treatment group. Post-Text TLFs will be provided in collated electronic MS Word .rtf files (i.e. table columns and rows appear in MS Word Table format). 

The statistical analyses of the study will be conducted in a GCP environment (ICH E6). 

All patient data will be collected via the electronic medical record and in-house ICU telemetry systems. Dedicated research personnel will
extract data to a de-identified study database for statistical analysis. 
  

	14.2	 Sample Size Calculation 

The sample size calculation of 144 subjects (2:1 allocation favoring the RLF-100 group) is required to

  

			
	  	  	Page | 21          

 

 
  

 detect a 25% absolute increase in the composite success percent for the RLF-100 group
(assuming 50% success) and the SOC group (assuming 25% success) with 83% power and two-sided 5% Type 1 error accounting for the group sequential design using the method in Schoenfeld. 

 

	14.3	 Study Populations 

The intent-to-treat (ITT) population will be based on all randomized patients receiving any study treatment. ITT will be analyzed as
randomized. 
 The safety population will be based on all randomized patients receiving any study treatment. Safety will be analyzed as
treated. 
 The modified intent-to-treat (mITT) population will exclude untreated patients as well as ineligible patients; this will be the
primary efficacy population. 
 The per protocol (PP) population will further exclude patients with major protocol deviations inclusive of,
but not limited to, going on another therapy which would have made them ineligible for the study as well as those with a major protocol deviation as judged by an independent Biostatistics Dara Review Meeting (BDRM). 

 

	14.4	 Statistical Methods 

Continuous variables, e.g., blood pressure, respiratory rate, tidal volume, organ function measurements will be summarized by mean ±
standard deviation, median, and range. Categorical variables, e.g., lung injury score, chest X-ray findings, will be summarized by frequency and corresponding % incidence. 

Evaluation of the primary endpoint (composite) will be analyzed by a pre-defined logistic regression model to include age (<65,
>65 years), baseline NIAID score (2, >2), RDR (<200 mmHg, >200 mmHg), previous anti-viral therapy for COVID-19 (none, any). and treatment as covariates; the method of Firth will be used to estimate unbiased treatment effects while
controlling for these four baseline covariates. Ordinal and continuous outcomes will be assessed by mixed model repeated measures (MMRM) through Day 28. Maximal signal is expected by 10 days. The primary analysis will be based on the modified
intent-to-treat (mITT) population. A Biostatistics Data Review Meeting will be conducted at study completion to determine final mITT population membership. 

Two pre-planned interim analyses will be conducted (n=30 for safety, n=81 for safety and futility). Should enrollment be increased to 144,
there will be 83% power to assess the primary endpoint Evaluation of the secondary endpoint, RCR, will be conducted by a mixed model repeated measures (MMRM) assuming unstructured covariance symmetry with sensitivity analyses to cover early
withdrawals; in the event that the unstructured covariance structure does not converge, then an autoregressive (1) structure will be tried, and if that does not work, then a Toeplitz structure will be tried. 

Time to event outcomes will be displayed using Kaplan-Meier lifetables to account for censoring in the estimation of the Day 28 outcomes;
Greenwood’s formula will be used to estimate Day 28 all-cause survival; time to event endpoints will be analyzed according to a stratified (RDR [<200 mmHg, >200 mmHg], previous anti-viral therapy for COVID-19 [none, any]) logrank test,
while time to resolution of respiratory failure and survival will also be analyzed using a proportional hazard model with the same four pre-defined covariates as for the primary efficacy endpoint; SAS PROC PHREG will be used to estimate unbiased
treatment effects while controlling for the above four baseline covariates. 
 For other endpoints, MMRM will be used based on available data
as well as imputing outcomes for subjects after death or worsening condition, e.g. ECMO or death, using last observation carried forward (LOCF). Time to (alive) hospital discharge will be displayed descriptively. 

  

			
	  	  	Page | 22          

 

 
  

 The NIAID score will be displayed over time. The area under the curve will also be calculated
and compared using an unpaired t-test. Patients dying prior to Day 28 will be carried through Day 28 as being dead. 
  

	14.5	 Interim Analysis, Futility/Safety 

Upon completion of observations through Day 7 for the first 30 subjects, an unmasked/unblinded analysis will be performed for the independent
DSMB in order to assess safety. Safety determinations will entail a review of AEs and SAEs by the independent Data Safety and Monitoring Board in consultation with FDA. Based on this evaluation, the DSMB/FDA will decide whether to permit adding
additional study sites and enrolling additional patients. 
 The second interim analysis will be assessed for safety, futility, and efficacy
once 81 subjects complete Day 14. Futility will be defined as no composite endpoint success percent advantage of RLF-100 over placebo when a 25% absolute advantage is expected. The study may be stopped for safety or futility (seeing a conditional
power ~10%). The study may be stopped for superiority (two-sided p=0.01). 
 Secondary efficacy analyses will include the overall
distribution of time to resolution of respiratory failure. 
 The DSMB will advise regarding the favorable benefit/risk associated with early
efficacy with safety. 
  

	15.	 HYPOTHESIS TESTS 

 

	15.1	 Treatment Comparisons 

Hierarchical testing will be used to preserve the Type 1 error associated with multiple endpoints (per FDA guidance). The testing order follows
with two-sided p=0.046 required to continue testing for label claims: 
 Primary Outcome Measure:  

Composite endpoint requiring each of the following to be met: 
  

	 	1)	 Resolution of respiratory failure by Day 10, and 

 

	 	2)	 Alive Day 28. 

Key Secondary Measure: 
  

	 	3)	 Time to resolution of respiratory failure, expect to see advantage by Day 10 

Secondary Outcome Measures: 
  

	 	4)	 Respiratory Distress while on mechanical ventilation: 

	 	            Blood	 PaO2/FiO2 ratio [Time Frame: enrollment through extubation] 

 

	 	5)	 Oxygenation Index 

  

	 	6)	 Improvement in chest x-ray 

 

	 	7)	 NIAID Ordinal Scale for Clinical Improvement 

 

	 	8)	 NIAID Area under the curve (AUC) 

Other Outcome Measures: 
  

	 	9)	 Survival lifetable 

  

	 	10)	 Time in ICU 

  

	 	11)	 Time on mechanical ventilation (to end of last mechanical ventilation) 

 

	 	12)	 Time on ventilation (to end of last ventilation) 

 

	 	13)	 Time to extubation (to end of last intubation) 

 

	 	14)	 Time to discharge alive (to end of last hospitalization) 

 

	 	15)	 Multi-organ failure free days 

 

	 	16)	 TNFα and other inflammatory markers 

  

			
	  	  	Page | 23          

 

 
  

	15.2	 Primary Hypothesis 

The null hypothesis (H0) is that there is no difference in the composite endpoint
success rate (SR) while the alternative hypothesis (Ha) is that there is a RLF-100 advantage in the composite endpoint success rate: 

H0:
SRRLF-100<SRPLA 

Ha:
SRRLF-100>SRPLA 
 A
25% absolute improvement in the success rate is deemed to be clinically meaningful. A 25% success rate is expected for Placebo + Maximal SOC while a >50% success rate is expected for RLF-100 + Maximal SOC. 

 

	15.3	 Primary Efficacy Endpoint: Composite Success 

The primary outcome measurement is the composite endpoint which is a binary success/fail endpoint where both components must be met to declare
success. Patients must have Day 28 follow-up to be declared a success. 
  

	15.4	 Key Secondary Efficacy Endpoint: Time to Resolution of Respiratory Failure 

Time to resolution of respiratory failure is defined as the latter of going off all ventilation and off high-flow O2. A Kaplan-Meier lifetable will be generated; a stratified logrank test and a proportional hazard model will be run to include the four previously stated endpoint covariates. Resolution will be
considered to be the event. 
  

	15.5	 Secondary Efficacy Endpoint: Blood PaO2/FiO2 Ratio (while on mechanical ventilation)

 Blood PaO2/FiO2 ratio is measured at every 24 hours with additional endpoint determinations through cessation of
mechanical ventilation. Time to normalization will be evaluated; this endpoint will also be analyzed using MMRM. 
  

	15.6	 Secondary Efficacy Endpoint: Oxygenation Index 

The Oxygenation Index is measured at every 24 hours and 28 days post intubation with additional endpoint determinations through cessation of
mechanical ventilation. Time to normalization (last SaO2 value >95%) will be evaluated; this endpoint will also be analyzed using MMRM. 
  

	15.7	 Secondary Efficacy Endpoint: Improvement in Chest x-ray 

The RALES score will be ascertained by a blinded radiologist panel. The percent with improvement in chest x-ray over time will be independently
determined by the panel. Percents improving will be compared using a two-sided Fisher Exact test while the RALES score distribution over time will be evaluated using MMRM. 
  

	15.8	 Secondary Efficacy Endpoint: NIAID 8-point Scale and Area Under the Curve 

The NIAID 8-point scale will be used as a measure of overall recovery from Critical COVID-19. The area under the curve (AUC) will be computed
from all available NIAID data through Day 28 including death; in addition, MMRM will be run for all available NIAID data through Day 28. 

  

			
	  	  	Page | 24          

 

 
  

	15.9	 Secondary Efficacy Endpoint: Survival 

Survival is defined as not having died as ascertained from the medical record. If death occurs post discharge and prior to Day 28, study
personnel will attempt to obtain a death certificate but may not succeed in the current emergency. A Kaplan-Meier lifetable will be generated; a stratified logrank test and a proportional hazard model will be run to include the four previously
stated endpoint covariates. All deaths from any cause are included in the survival analysis; the 28-day all-cause survival will be estimated from the Kaplan-Meier lifetable. 
  

	15.10	 Other Efficacy Endpoints: ICU, Ventilations, Extubation, and Discharge 

Kaplan-Meier lifetables will be generated for each of the time to last ICU release, time to last going off ventilation and mechanical
ventilation, and time to extubation. Time to alive discharge will be a descriptive statistic (mean, SD, range) for the subset alive at discharge. 
  

	15.11	 Other Efficacy Endpoint: Multi-system Organ Failure 

The days free of multi-system organ failure will be computed; organs include sepsis, blood, brain, heart, liver, and kidneys. Written
guidelines for specific organ failure will be separately generated prior to database lock. The days free of multi-system organ failure will be assessed using the Schoenfeld method. 

 

	15.12	 Laboratory Efficacy Endpoints: Inflammatory Markers 

The secondary laboratory outcome measures are TNFα, IL6, and other inflammatory markers as measured in the central laboratory. 

 

	15.13	 Overall Safety Endpoints 

All safety results will be presented separately for each treatment group. Safety endpoints will include adverse events (AE), vital signs (VS),
and relevant clinical chemistries and hematology parameters. Safety and tolerability will be assessed using two-sided Fisher Exact tests to compare RLF-100 vs. Placebo. Mean changes from randomization baseline will be displayed for each serum
chemistry and hematology parameter as well as the shift; unpaired t-tests will be used to compare RLF -100 vs. Placebo at designated study times. In addition, paired t-tests will be performed for the change from randomization baseline within each
study treatment group. 
  

	16.	 SOURCE DATA & DOCUMENTS 

 

	16.1	 Sources of Research Materials 

The following source data and documents will be collected. All blood samples, except those taken for cytokine and arachidonate metabolite level
monitoring, which would be part of this investigation, would be obtained in the normal course of clinical care of these patients as described above. 
  

	16.2	 Case Report Form 

The Case Report Form (CRF) is an integral part of the study and subsequent reports. The CRF must be used to capture all study data recorded in
the patient’s medical record. The CRF must be kept current to reflect patient status during the study. Only a patient screening and randomization number will be used to identify the patient. 

 

	16.3	 Patient Identification

	  	  	Page | 25          

 

 
  

	16.4	 General Clinical Data 

Primary diagnosis, coexisting diagnoses / conditions, hospital length of stay and outcome will be collected. 

 

	16.5	 Lung Injury / ARDS Data 

PaO2/FiO2 ratio; PEEP/CPAP;
peak, mean & plateau pressures; compliance (dynamic and quasi-static); tidal volume; respiratory rate; minute ventilation, lung injury score, chest X-ray findings will be collected. 

 

	16.6	 Laboratory Data 

Arterial blood pH, PCO2, PO2;
electrolytes (Na, K, Cl, HCO3); renal function (BUN, serum creatinine); glucose, albumin & total plasma proteins; liver function tests; blood cell count; coagulation profile; lactic acid and D-Dimer
will be collected. 
  

	16.7	 Vital Signs, Respiratory and Hemodynamic Data 

Blood pressure (systolic, diastolic, mean), heart rate, respiratory rate, cardiac output/cardiac index, pulmonary artery (PA) wedge pressure,
systolic, diastolic & mean pressures (if PA catheter is in place), right atrial/central venous pressure, systemic and pulmonary vascular resistance, systemic 02 delivery, daily urine output, daily fluid intake will be collected. 

 

	16.8	 Medical Therapy Data

nutritional therapy will be collected. 
 The therapeutic milieu for RLF100-001 – ICU-type settings during the COVID-19 pandemic – requires a thoughtful and practical approach to the capture of concomitant medications in clinical studies. Specifically,
the capture of relevant concomitant medications is required under three circumstances: 
 1. As part of a relevant medical history entry,
where relevant medical history is defined as relating to an inclusion or exclusion criteria; 
 2. As part of an AE entry, for agents
administered in response to the AE; and 
 3. Agents of interest, namely Biotin, IL6, antiviral therapies, steroids, nitric oxide,
epoprostenol (Flolan), pressors (e.g., norepinephrine, epinephrine, Vasopressin), paralytics, anticoagulants, convalescent plasma, and tocilizumab (Actemra) and other immunomodulators. 

Please note there is a unique dedicated CRF page for capturing concomitant use of convalescent plasma – no need for a duplicate entry on a
concomitant medication form. 
 Furthermore, sites will be asked to report unusual circumstances in their ICU that require medical therapy
that can negatively affect the prognosis of a patient, e.g. emergence of treatment resistant bacteria leading to high mortality. 
  

	16.9	 Pharmacokinetic Sampling 

The pharmacokinetics of intravenous Aviptadil are well understood and do not require revalidation in this study. 

 

	16.10	 Blood Sampling 

Blood samples are obtained for biochemical, electrolyte, and hematologic profiles per ICU protocol. Blood samples for cytokine (TNF-alpha, IL-6, which correlate with the inflammatory response and with mortality levels are obtained before, at 2 hours and at 12 hours, and then daily on day 5, day 7 and
day 28 or day of discharge. Leukotrine E4 (urine) and Plasma VIP levels are checked at the same intervals to ensure the delivery of the peptide into the circulation. Plasma is separated within 30 min, frozen and stored at -70 C until the assays are performed, by specific radio-immunoassays or ELISA. Additionally, D-Dimer may be added when available.

	17.	 STUDY MONITORING 

 

	17.1	 Study Monitoring 

The study sites have been evaluated by the sponsor in conjunction with the CRO to determine suitability for the proposed study. Information
reviewed included, but was not be limited to, facility details and site capabilities, past performance in similar studies, investigator, and staff experience, ongoing studies at the site, projected enrollment in this study, and FDA or other agency
audit findings. Prior to subject enrollment, a virtual study initiation visit will be completed by video conference to ensure the following: IRB approval has been obtained and documented prior to subject screening, the investigators and study
personnel are appropriately trained and clearly understand the study, the investigators and study personnel accept the obligations incurred in undertaking this clinical investigation. 

Periodic remote monitoring visits will be made in accordance with the approved monitoring plan at all active study sites throughout the
clinical study to assure that the investigator obligations are fulfilled, and all applicable regulations and guidelines are being followed. These visits will assure that the facilities are still compliant with study requirements, the protocol and
investigational plan are being followed, the IRB has been notified of approved protocol changes as required, complete records are being maintained, appropriate and timely reports have been made to the sponsor and the IRB, and the site Investigator
is executing all agreed activities. Given the public health crisis, these visits will done via virtual means and specific monitoring arrangements with each site. 
  

	17.2	 Data Safety and Monitoring 

All results from this study will be reviewed by a Data Safety and Monitoring Committee, chaired by Prof. Alfred Sommer, MD, MHS, Dean Emeritus
of the Bloomberg School of Public Health. Membership of this committee will include: a clinician specialist in Critical Care Medicine, a biostatistician, and a lay patient advocate. The committee will critique the progress of the trial, carefully
examine any incidents of adverse reactions, and may suggest appropriate revisions in the protocol. DSMB functions include, among others, ongoing assessment of masked data to determine whether any of the treatment arms show increased risk for AEs.

  

			
	  	  	Page | 27          

 

 
  

	17.3	 Medical Monitor 

The Medical Monitor will review and approve the eligibility of all screened subjects, review all AEs, assess the benefits and risks of
protocols on an ongoing basis, and work in collaboration with the IRB and DMC to identify safety signals and trends. In addition, the Medical Monitor will be available for site questions regarding inclusion/exclusion criteria, protocol conduct, and
safety. Trained and qualified physicians will be available to provide coverage during times when the medical monitor is unavailable. Sites will be provided with the Medical Monitor’s cell phone number for emergency situations. Otherwise, sites
are instructed to contact the Medical Monitor through email. All critical conversations with sites will be documented by the Medical Monitor and reviewed periodically by the sponsor. Each month the Medical Monitor will receive a listing of protocol
violations for review and identification of possible trends. 
  

	17.4	 Audits and Inspections 

Contracts with study sites will specify that sponsor or its representatives will have direct access to source data and documents for study
monitoring, which may be done through virtual/electronic means. Additionally, the IRB and FDA may review source data following appropriate guidelines for this process. 
  

	17.5	 Institutional Review Board 

The study protocol and any amendments will be reviewed by the Advarra Institutional Review Board (IRB). The IRB will review the informed
consent form, their updates (if any), and any written materials given to the participants. IRB approval will be obtained and documented prior to subject enrollment and screening. Before study initiation, the investigator must have written and dated
approval from the IRB for the protocol, consent form, subject recruitment materials/process (e.g., advertisements), and any other written information to be provided to subjects. The investigators will provide the IRB with reports, updates, and other
information (e.g., Safety Updates, Amendments, and Administrative Letters) according to regulatory requirements and Institution procedures. A detailed list of required regulatory documents, to be submitted to the sponsor, will be sent upon final
approval of the protocol. 
  

	18.	 ETHICAL CONSIDERATIONS 

 

	18.1	 Ethical Considerations 

Anticipated benefits to participants and others: There are at present no satisfactory specific treatments for ARDS, or multiple
organ dysfunction. Based on a large body of experimental work, there is reason to expect that RLF-100 (aviptadil) may prove effective in increasing survival rates in
COVID-19 patients with ARDS, as well as increasing blood 02, reducing organ failure and reducing cytokine cascades. 

Anticipated risks to participants and others: The only anticipated risks are due to the side-effects noted above of hypotension,
tachycardia and watery diarrhea. Aviptadil has been evaluated in 4 species toxicology studies and the LD50 is more than 50x the exposure contemplated in this trial. 
  

	18.2	 Ethical Conduct of the Study 

This study will be conducted in accordance with the ethical principles that have their origins in the Declaration of Helsinki, in compliance
with the approved protocol, GCP, and applicable regulatory requirements. 
  

	18.3	 Informed Consent 

The patient’s legally authorized representative (LAR) must be capable of understanding the nature of this study and its potential risks,
discomforts, and benefits. Study physicians or their delegate will obtain consent after they have fully explained the study purpose and procedures, and the LAR has demonstrated an understanding of the protocol, willingness to participate, and
competency to consent. The investigator or their delegate must ensure that subjects are clearly and fully informed about the purpose, potential risks, 

  

			
	  	  	Page | 28          

 

 
  

 and other critical issues regarding clinical trials in which they volunteer to participate.
Preparation of the site-specific consent form is the responsibility of the site Principal investigator and must include all elements required by CFR 21 Part 50.25 and the IRB. 

 

	19.	 DATA HANDLING & RECORD KEEPING 

 

	19.1	 Data Capture 

An investigator is required to prepare and maintain adequate and accurate case histories designed to record all observations and other data
pertinent to the investigation on everyone treated with the investigational product or entered as a control in the investigation. 
  

	19.2	 Data Collection 

No manual data collection is anticipated in the ICU. Data will be extracted from the EMR and other sources by hospital clinical research staff
in a HIPAA-compliant, de-identified manner and transferred to the study database. 
  

	19.3	 Retention of Records 

The investigator must retain investigational product disposition records, case report forms, and source documents for the maximum period
required by applicable regulations and guidelines, or in accordance with institution procedures, and at least for 10 years. This is study practice in the study sites. 
  

	19.4	 Use of Information and Publication Policy 

All publications will be reviewed by the sponsor for accuracy before submission to peer-reviewed journals or scientific meetings. Abstracts
will be submitted for review at least 10 days before submission, and publications should be submitted for review at least 30 days before submission. The study will be posted to Clinicaltrials.gov, and results will be reported in accordance with
Clinicaltrials.gov guidelines.
