PRODUCT produced for sale in the United States will be manufactured substantially in the United States, to the extent required by Federal law, unless appropriate waivers shall have been obtained as provided by law.

 

2.2                               The term of this agreement and the exclusive license set forth in Paragraph 2.1 shall be from the effective date of this Agreement until the expiration of the last to expire of the PATENT RIGHTS.

 

2.3                               The granting and acceptance of this license is subject to the following conditions:

 

(a)                                 The UI Patent Policy approved in 1983, Public Law 96-517, Public Law 98-620 and UIRF’s obligations under agreements with other sponsors of research as of the Effective Date of this Agreement (UIRF represents that to the best of its knowledge the sole sponsors of research relating to Patent Rights are the VA and the United States National Institutes of Health). Any right granted in this Agreement greater than that permitted under Public Law 96-517 or Public Law 98-620 shall be subject to modification as may be required to conform to the provision of that statute. UIRF represents that the Public Laws 96-517 and 98-620 are consistent with and do authorize the grant of rights made under 2.1 above.

 

(b)                                 The right to grant non-commercial licenses on reasonable terms and conditions under 35U.S.C.§200-212 or 15 U.S.C. 3710a, and other applicable governmental implementing regulations, whichever may be appropriate.

 

(c)                                  UIRF reserves for itself, Inventors, and future not-for-profit employers of Inventors, the right to make and to use for educational, research, and patient care and treatment purposes (with respect to patient care and treatment, at UIRF only) only, the subject matter described and claimed in PA VENT RIGHTS. UIRF further reserves the right to provide and to grant non-exclusive licenses to make and use subject matter covered by PATENT RIGHTS to not-for-profit organizations and government entities for internal research and scholarly purposes only.

 

(d)                                 Licensee shall pay all future costs connected with the commercial development of the LICENSED PRODUCTS, including but not limited to the costs of complying with applicable governmental testing, approvals and regulations.

 

(e)                                  Licensee shall use reasonable efforts to effect introduction of the LICENSED PRODUCTS into the commercial market as soon as practicable, consistent with sound and reasonable business practices and judgment; thereafter, until the expiration of this Agreement, Licensee shall endeavor to keep LICENSED PRODUCTS reasonably available to the public.

 

(f)                                   Licensee has submitted to UIRF a development plan attached hereto as an appendix. Licensee shall use commercially reasonable efforts to follow the development plan. The development plan shall include benchmark dates for development as negotiated by Licensee and UIRF. Licensee shall demonstrate compliance with the benchmark dates set out in the development plan, or shall demonstrate to UIRF’s reasonable satisfaction that Licensee (Or Affilliates or sublicensees, as the case may be) has taken, or can be expected to take within a reasonable time, effective steps to correct the failure to achieve the relevant benchmark in order to achieve that benchmark within the earliest reasonably possible time. If Licensee has not met the milestones in the development plan, either as originally listed or agreed to by UIRF after demonstration by Licensee, UIRF may furnish Licensee with written notice of the determination thereof. Within sixty (60) days after receipt of the notice, Licensee shall either, at its option (i) fulfill the relevant obligation, or (ii) provide to UIRF a mutually acceptable schedule of revised diligence obligations and plans to meet the same. In the case of (ii), UIRF and Licensee shall meet and discuss such revised

obligations and plans, and UIRF shall consider such revisions in good faith. If the UIRF does not find the revised timeline, data and plan reasonably acceptable in its good faith discretion, UIRF may, upon fifteen (15) days written notice to Licensee, terminate the license granted under this Agreement

 

(g)                                  All sublicenses granted by Licensee hereunder shall include a requirement that the sublicensee use efforts at least equivalent to those required of Licensee to bring the subject matter of the sublicenses into commercial use as quickly as is reasonably possible, and shall bind the sublicensee to meet Licensee’s obligations to UIRF under this Agreement and a copy of this Agreement shall be attached to such sublicense agreements. Royalties charged for sublicenses by Licensee shall not be in excess of normal trade practice. Copies of all sublicense agreements shall be provided to UIRF.

 

(h)                                 In accordance with the rights reserved to the Government under 35 U.S.0 §203 and succeeding statutes, the Government shall retain the right to require UIRF or its Licensee to grant a sublicense to a responsible applicant on terms that are reasonable under the circumstances. The Government may exercise its tights retained herein only in exceptional circumstances and only if the Government determines that (i) the action is necessary to meet health or safety needs that are not reasonably satisfied by UIRF; (ii) the action is necessary to meet requirements for public use specified by Federal regulations, and such requirements are not reasonably satisfied by UIRF; or (iii) UIRF has failed to comply with an agreement containing provisions described in 35 U.S.0 §204 or 15 U.S.0 3710a©(4)(B), whichever is appropriate.

 

(i)                                     A license in any other field of use in addition to the FIELD shall be the subject of a separate agreement and shall require Licensee’s submission of evidence, satisfactory to UIRF, demonstrating its willingness and ability to develop and commercialize the kinds of products or processes likely to be encompassed in such other field. If UIRF has non-exclusively licensed in such other field prior to Licensee’s request, HIRE shall grant to Licensee a non-exclusive license under terms and conditions at least as favorable as the previous non-exclusive license.

 

2.4                               UIRF hereby grants to Licensee the right to extend the licenses granted or to be granted in paragraphs 2.1 and 2.3 to an AFFILIATE subject to the terms and conditions hereof.

 

2.5                               All rights reserved to the United States Government and others under Public Law 96-517, 98-620, 35U.S.C.§200-212, 37 CFR part 401 et.al., and succeeding statutes. To the extent set out in those statutes, the Government shall have the nonexclusive, nontransferable, irrevocable, royalty-free, paid-up right to practice or have practiced the PATENT RIGHTS throughout the world by or on behalf of the Government and on behalf of any foreign government or international organization pursuant to any existing or future treaty or agreement to which the Government is a signatory.

5.1                               Licensee shall keep, and shall require its AFFILIATES and sublicensees to keep, accurate and correct records of LICENSED PRODUCTS made, used or sold under this Agreement, appropriate to determine the amount of royalties due hereunder to UIRF.

hundred twenty (120) days of the Effective Date. Licensee shall reimburse UIRF seventy-five percent (75%) for all such future expenses upon receipt of invoices from UIRF, thirty (30) days net. Late payment of these invoices shall be subject to interest charges of one and one-half percent (1 1/2%) per month. UIRF represents that the two current agreements for the patent rights shall total one-hundred percent (100%) reimbursement of all patent costs. UIRF further agrees that through duration of this License Agreement, should UIRF license the Patent Rights to another third party, then UIRF shall inform Licensee and agree with Licensee to an appropriate pro rata reduction (based on the costs of prosecution associated with Patent Rights licensed to such third party) in Licensee’s contribution to the patent expenses. UIRF shall take responsibility for the preparation, filing, prosecution and maintenance of any and all patent applications and patents included in PATENT RIGHTS. UIRF shall promptly inform Licensee regarding all matters directly pertaining to prosecution of PATENT RIGHTS, and shall seek Licensee’s counsel concerning all proposed course of action affecting the PATENT RIGHTS, including but not limited to in which countries patent protection should be obtained and all proposed course of action in any interference proceedings.

 

6.2                               UIRF and Licensee shall cooperate fully in the preparation, filing, prosecution and maintenance of PATENT RIGHTS and of all patents and patent applications licensed to Licensee hereunder, executing all papers and instruments or requiring members of UIRF to execute such papers and instruments as to enable UIRF to apply for, to prosecute and to maintain patent applications and patents in UIRF’s name in any country. Each party shall provide to the other prompt notice as to all matters which come to its attention and which may affect the preparation, filing, prosecution or maintenance of any such patent applications or patents.

 

6.3                               If Licensee elects to no longer pay the expenses of a patent application or patent included with PATENT RIGHTS, Licensee shall notify UIRF not less than sixty (60) days prior to such action and shall thereby surrender its rights under such patent or patent application.

 

ARTICLE VII — MARKING

 

7.1                               If a licensed patent has been or is subsequently issued to UIRF covering any feature or features of the LICENSED PRODUCTS, Licensee agrees to mark each and every package or container in which the LICENSED PRODUCTS are used or sold by or for Licensee with marking complying with the provisions of Title 35, U.S. Code, Section 287, if required, or any future equivalent provisions of the United States relating to the marking of patented devices, or with marking complying with the law of the country where the LICENSED PRODUCTS are shipped, used or sold.

 

ARTICLE VIII — INFRINGEMENT

 

8.1                               With respect to any PATENT RIGHTS under which Licensee is exclusively licensed in a FIELD pursuant to this Agreement, Licensee or its sublicensee shall have the right to prosecute in its own name and at its own expense any infringement within the FIELD of such patent, so long as such license is exclusive at the time of the commencement of such action. UIRF agrees to notify Licensee promptly of each infringement of such patents of which UIRF is or becomes aware. Before Licensee or its sublicensees commences an action with respect to any infringement of such patents Licensee shall give careful consideration to the views of UIRF and to potential effects on the public interest in making its decision whether or not to sue and in the case of a Licensee sublicense, shall report such views to the sublicensee.

 

8.2                               If Licensee elects to sue for patent infringement, UIRF agrees to be named as nominal third party plaintiff if necessary to the commencement of any such action, and further agrees to provide any information available to UIRF and needed by Licensee in prosecuting such action. Licensee shall

reimburse UIRF for any costs it incurs as part of an action brought by Licensee or its sublicensee, irrespective of whether UIRF shall become a co-plaintiff.

 

8.3                               If Licensee or its sublicensee elects to commence an action as described above, Licensee may reduce, by up to fifty percent (50%), the royalty due to UIRF earned under the patent subject to suit by fifty percent (50%) of the amount of the expenses and costs of such action, including attorney fees. In the event that such fifty percent (50%) of such expenses and costs exceed the amount of royalties withheld by Licensee for any calendar year, Licensee may to that extent reduce the royalties due to UIRF from Licensee in succeeding calendar years, but never by more than fifty percent (50%) of the royalty due in any one year.

 

8.4                               No settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the consent of UIRF, which consent shall not be unreasonably withheld.

 

8.5                               Recoveries or reimbursements from such action shall first be applied to reimburse Licensee and UIRF for litigation costs not paid from royalties and then to reimburse UIRF for royalties withheld. Any remaining recoveries or reimbursements shall be shared 75% to the Party electing to pursue and 25% to the other Party.

 

8.6                               In the event that Licensee and its sublicensee, if any, elect not to exercise their right to prosecute an infringement of the PATENT RIGHTS pursuant to the above paragraphs, UIRF may do so at its own expense, controlling such action and sharing recoveries as provided in section 8.5.

 

8.7                               If a declaratory judgment action alleging invalidity of any of the PATENT RIGHTS shall be brought against Licensee, or UIRF, then UIRF, at its sole option, shall have the right to intervene and take over the sole defense of the action at its own expense.

 

8.8                               UIRF shall have no obligation to defend any action for infringement brought against Licensee by a third party. In the event Licensee is sued by a third party, and as a result of the settlement of such suit is required to pay a royalty to a third party on a LICENSED PRODUCT, the amount of royalty paid will be deducted from the royalty payment due to the UIRF for that LICENSED PRODUCT. In the event the settlement prevents the Licensee from continuing sales of a LICENSED PRODUCT, no additional royalties and/or minimum royalties will apply for that LICENSED PRODUCT.

 

ARTICLE IX — TERMINATION OF AGREEMENT

 

9.1                               Upon any termination of this Agreement, and except as provided herein to the contrary, all rights and obligations of the Parties hereunder shall cease, except as follows:

 

(a)                                 UIRF’s right to receive or recover and Licensees obligation to pay royalties accrued or accruable for payment at the time of any termination;

 

(b)                                 Licensees obligation to maintain records and UIRF’s right to conduct a final audit as provided in Article V of this Agreement; and

 

(c)                                  Any cause of action or claim of UIRF, accrued or to accrue because of any breach or default by Licensee.

 

9.2                               In the event Licensee fails to make payments due hereunder, UIRF shall have the right to terminate this Agreement upon forty-five (45) days written notice, unless Licensee makes such payments

 

9

plus interest within the forty-five (45) day notice period. If payments are not so made, UIRF may immediately terminate this Agreement.

 

9.3                               In the event that Licensee shall be in default in the performance of any obligations under this Agreement (other than as provided in 9.2 above which shall take precedence over any other default), and if the default has not been remedied within ninety (90) days after the date of notice in writing of such default, UIRF may terminate this Agreement immediately by written notice.

 

9.4                               If Licensee shall (a) make a general assignment for the benefit of creditors, (b) file or have filed against it a petition in bankruptcy or seeking reorganization (and, in the case of a petition filed against Licensee, such petition is not dismissed or stayed by the earlier of the date that is (i) 90 days after the date that such petition is filed, or (ii) the date that an order for relief is granted by the bankruptcy court in connection therewith), (c) voluntarily commence any case, proceeding or other action or file any petition seeking relief under Title 11 of the United States Code, (d) consent to the institution of, or fail to controvert in a timely and appropriate manner, any such proceeding or the filing of any such petition, or (e) apply for or consent to the employment of a receiver, trustee, custodian, sequestrator or similar official in bankruptcy for the Licensee; then Licensee shall notify UIRF and provide its plan, if any, for emerging from such proceeding or removing such assignment. UIRF shall review the plan in good faith and, if deemed sufficient in its reasonable discretion to emerge from such proceeding or remove such assignment, shall maintain this Agreement for a reasonable time; otherwise, it shall have the right to terminate this Agreement upon thirty (30) days written notice. In the event that Licensee commences any bankruptcy proceeding, it shall not thereafter deliver any Patent Rights constituting intellectual property (or any embodiments of such intellectual property) to any third party.

 

9.5                               Any sublicenses granted by Licensee under this Agreement shall provide for termination or assignment to UIRF, at the option of HIRE, of Licensee’s interest therein upon termination of this Agreement, except that UIRF will, to the extent it is legally able to do so, offer to the sublicensee a license agreement as immediately described below, provided that the sublicensee: CO reaffirms the terms and conditions of this Agreement as it relates to the rights the sublicensee has been granted under the sublicense; (ii) agrees to abide by all of the terms and conditions of this Agreement applicable to such sublicensee. and to discharge directly all pertinent obligations of Licensee which Licensee is obligated hereunder to discharge; (iii) acknowledges that UIRF shall have no obligations to the sublicensee other than its obligations set forth in the License Agreement with regard to Licensee; and (iv) can demonstrate to UIRF that sublicensee has at least an equal amount of capital and ability as Licensee to diligently advance the Patent Rights for commercial use. UIRF agrees that, provided UIRF receives notice that complies with the immediately preceding sentence, and sublicensee is not in breach of its sublicense, UIRF shall grant to such sublicensee license rights and terms equivalent to the sublicense rights and terms which Licensee shall have granted to said sublicensee.

 

9.6                               Licensee shall have the right to terminate this Agreement by giving ninety (90) days advance written notice to DIRE to that effect. Upon termination, a final report shall be submitted and any royalty payments and unreimbursed patent expenses due to DIRE become immediately payable.

 

9.7                               Licensee shall have the right during a period of six (6) months following the effective date of such termination to sell or otherwise dispose of the LICENSED PRODUCT existing at the time of such termination, and shall make a final report and payment of all royalties related thereto within sixty (60) days following the end of such period or the date of the final disposition of such inventory, whichever first occurs.

 

9.8                               Termination of this agreement to a LICENSED PRODUCT shall not alter the rights and obligations of the parties to the remaining LICENSED PRODUCTS.

ARTICLE X — ASSIGNMENT

 

10.1                        The rights and licenses granted by UIRF in this agreement are specific and may not be assigned or otherwise transferred to any party other than to the acquirer of substantially all the business interest of Licensee relating to the PATENT RIGHTS, without the prior written approval of UIRF. Any attempted assignment or transfer without such approval except as provided in the preceding sentence shall be void and shall automatically terminate all rights of Licensee under this Agreement.

 

ARTICLE XI — REPRESENTATIONS AND WARRANTIES: LIMITATIONS

 

11.1                        Nothing in this agreement shall be construed as:

 

(a)                                 A warranty or representation by UIRF as to the validity or scope of any LICENSED PATENT; or

 

(b)                                 A warranty or representation that anything made, used or sold under the license granted in this agreement is or will be free from infringement of patents owned by third parties; or

11.2                        UIRF represents that, to the best of its knowledge, anything made, used or sold under this agreement will be free from infringement of patents of third parties.

 

11.3                        UIRF EXPRESSLY DISCLAIMS ANY AND ALL IMPLIED OR EXPRESS WARRANTIES AND MAKES NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OF THE PA PENT RIGHTS, OR INFORMATION SUPPLIED BY UIRF, LICENSED PROCESSES OR LICENSED PRODUCTS CONTEMPLATED BY THIS AGREEMENT. UIRF assumes no responsibilities whatever with respect to design, development, manufacture, use, sale or other disposition by Licensee or AFFILIATES of LICENSED PRODUCTS, or LICENSED PROCESSES.

ARTICLE XII — GENERAL

 

12.1                        (a)                                 Licensee shall indemnify, defend and hold harmless UIRF and the University of Iowa and their current or former directors, governing board members, trustees, officers, faculty, medical and professional staff, employees, students, and agents and their respective successors, heirs and assigns (the “Indemnities”), against any liability, damage, loss or expenses (including reasonable attorneys’ fees and

expenses of litigation) incurred by or imposed upon the Indemnities or any one of them in connection with any claims, suits, actions, demands or judgments arising out any theory of product liability (including, but not limited to, actions in the form of tort, warranty, or strict liability) concerning any product, process or service made, used or sold pursuant to any right or license granted under this Agreement.

 

(b)                                 Licensee agrees, at its own expense, to provide attorneys reasonably acceptable to UIRF to defend against any actions brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought.

 

(c)                                  Beginning at the time as any such product, process or service is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by Licensee or AFFILIATE or agent of Licensee, Licensee shall, at its sole cost and expense procure and maintain Commercial General Liability insurance in amounts not less than $2,000,000 per occurrence and $2,000,000 annual aggregate and naming the Indemnitees as additional insureds. During clinical trials of any such product, process or service Licensee shall, at its sole cost and expense, procure and maintain Commercial General Liability insurance in such equal or lesser amounts as UIRF shall require, naming the Indemnitees as additional insureds. Such Commercial General Liability insurance shall provide coverage for bodily injury and property damage, including completed operations, personal injury, coverage for contractual employees, blanket contractual and products and completed operations. 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 must be acceptable to UIRF. The minimum amounts of insurance coverage required shall not be construed to create a limit of Licensee’s liability with respect to its indemnification under this Agreement. Policy shall contain a severability of interests provision.

 

(d)                                 Licensee shall provide UIRF with a certificate of liability insurance at the time insurance is required under 12.1 (c). Licensee shall provide UIRF with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance; if Licensee does not obtain replacement insurance providing comparable coverage within such thirty (30) day period, UIRF shall have the right to terminate this Agreement effective at the end of such thirty (30) day period without notice or any additional waiting periods.

 

(e)                                  Licensee shall maintain such Commercial General Liability insurance beyond the expiration or termination of this Agreement during (i) the period that any product, process, or service, relating to, or developed pursuant to, this Agreement is being commercially distributed or sold by Licensee or by a sublicensee, AFFILIATE or agent of Licensee and (ii) a reasonable period after the period referred to in (e)(i) above which in no event shall be less than fifteen (15) years.

 

12.2                        In the event of any controversy or claim arising out of or relating to any provision of this Agreement or the breach thereof, the parties shall try to settle such conflicts amicably between themselves. Subject to the limitation stated in the final sentence of this section, any such conflict which the parties are unable to resolve may be settled through arbitration conducted in accordance with the rules of the American Arbitration Association. In the event a dispute is arbitrated, the demand for arbitration shall be filed within a reasonable time after the controversy or claim has arisen, and in no event after the date upon which institution of legal proceedings based on such controversy or claim would be barred by the applicable statutes of limitation. Such arbitration shall be held in Des Moines, Iowa. The award through arbitration shall be final and binding. Either party may enter any such award in a court having jurisdiction or may make application to such court for judicial acceptance of the award and an order of enforcement, as the case may be. Notwithstanding the foregoing, either party may, without recourse to

arbitration, assert against the other party a third-party claim or cross-claim in any action brought by a third party, to which the subject matter of this Agreement may be relevant.

 

12.3                        Should a court of competent jurisdiction later consider any provision of this Agreement to be invalid, illegal, or unenforceable, it shall be considered severed from this Agreement. All other provisions, rights and obligations shall continue without regard to the severed provision, provided that the remaining provisions of this Agreement are in accordance with the intention of the parties.

 

12.4                        No waiver by a Party of any breach of this Agreement, no matter how long continuing or how often repeated, shall be deemed a waiver of any subsequent breach thereof, nor shall any delay or omission on the part of a Party to exercise any right, power or privilege hereunder be deemed a waiver of such right, power or privilege.

 

12.5                        The relationship between the Parties is that of independent contractor and contractee. Licensee shall not be deemed to be an agent of UIRF in connection with the exercise of any rights hereunder, and shall not have any right or authority to assume or create any obligation or responsibility on behalf of UIRF.

 

12.6                        No party hereto shall be deemed to be in default of any provision of this Agreement, or for any failure in performance, resulting from acts or events beyond the reasonable control of such Party, such acts of God, acts of civil or military authority, civil disturbance, war, strikes, fires, power failures, natural catastrophes or other “force majeur” events.

 

ARTICLE XIII — NOTICES; APPLICABLE LAW

APPENDIX B

 

PanaecinTM Product Development Plan

 

Background
 Gallium has an extensive history of therapeutic use in humans. It is the active component of a commercial product (Ganite®) that is used to treat hypercalcemia related to cancer (1). In addition, there is a rich clinical history testing various gallium salts in over 1,000 cancer patients (2,3) and using 67Ga scans to detect areas of infection and inflammation. As a result, there is a well understood safety profile of gallium nitrate when administered in large doses (200-400 mg/24h), both acutely and chronically, and as an intravenous (iv) infusion. More recently, the anti-infective properties of gallium have been increasingly recognized. Gallium is a semi-metallic compound with similar chemical characteristics to iron, particularly in atomic radius and electron negativity. It binds to many iron binding proteins, such as bacterial siderophores, and unlike iron, gallium cannot be reduced, or readily dislodged from iron binding proteins, since sequential oxidation and reduction are critical for many of iron’s biological functions. As a consequence, many critical enzymatic pathways in bacteria, which require iron, such as DNA synthesis, metabolic conversion, electron transport and oxidative stress defense are disrupted leading to growth inhibition (4). This mechanism of action mimics that of host defenses, which have evolved to combat both acute and chronic infection by sequestering iron. Thus, gallium is a new anti-infective with a mechanism of action that differs from all current antibiotics. One of the most extensive studies of the antibacterial activity of gallium has been performed with P. aeruginosa. Gallium inhibits P. aeruginosa growth with a minimum inhibitory concentration (MIC90) and minimum bactericidal concentration (MBC) of approximately 10 pM (0.7 pg/mL; ref. 5). Furthermore, gallium nitrate inhibits the formation of P. aeruginosa biofilms at 0.1 pg/mL and disrupts pre-existing biofilms at 7 pg/mL (5).

 

Preclinical Development
 Studies at Aridis have shown that gallium has excellent activity against P. aeruginosa clinical isolates with varying degrees of antibiotic resistance (Table 1) with 10 of 11 strains exhibiting complete inhibition at gallium concentrations below 1 ug/mL. Time to kill kinetics also demonstrated that even at concentrations 10-fold lower than the maximally achievable clinical dose, P. aeruginosa was completely killed within 3 hours of exposure to gallium (Figure 1). Furthermore, the activity of gallium against a broad spectrum of bacteria (Appendix 1, Table 4) particularly those that chronically colonize the lungs of CF patients, such as P. aeruginosa, Burkholderia cepacia, Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) confirms that it is a promising drug candidate for treatment of chronic lung infections in CF patients, non-CF bronchiectasis patients and for the treatment of chronic obstructive pulmonary disease (COPD).

Process Development and Manufacturing Drug Substance
  Bulk GMP material (drug substance) suitable for clinical testing is commercially available from several contract manufacturers. Aridis evaluated Regis Technologies, Inc. (Morton Grove, IL) and Johnson Matthey (West Deptford, NJ) as contract manufacturers and will purchase GMP drug substance for initial clinical testing from one of these vendors.

 

Formulation Development
 Rationale for the use of inhaled gallium for the treatment of lung infections

(200-400 mg/24h), both acutely and chronically (2,3). Aridis’ projected pulmonary daily dose (15 mg of gallium nitrate) is a small fraction of the iv doses used with the GaniteTM product.

 

Progression toward reduced systemic exposure, reduced dose and administration time with inhalable antibiotics.
  Current therapies to control P. aeruginosa infections in CF patients are inconvenient and exert a limited impact on mortality. The current standard of care to treat P. aeruginosa lung infections in CF patients, which represents a significant advancement, is twice-daily treatment of tobramycin solution administered by oral inhalation for alternating 28-day on/off cycles. Pulmonary delivery has been shown to significantly increase local lung bioavailability and reduce systemic toxicity (Figure 2). The downside of pulmonary administration is that CF patients may spend nearly three hours on an average day on inhalation therapy (i.e. saline solution, antibiotic and DNase treatment; 6), which impacts their quality of life and has become an important factor in the development of new drug therapies. In this regard, recent advances in powder inhalers and more efficient liquid nebulizers have enabled a marked reduction in dose level and dosing time.

We will develop gallium as an inhaled therapy, because it maximizes the dose at the site of infection and minimizes the systemic exposure. Gallium has been formulated into a liquid that can be readily inhaled into the lungs using a commercially available nebulizer device (Aeroneb® Go, Aerogen, Inc.). In preliminary preclinical studies, gallium administered into the lungs of rats intratracheally was shown to have a lung half-life of 16.5 hrs, which may allow a dosing frequency of about once a day. We will extend these studies by producing material initially for preclinical testing and GLP toxicology studies, and subsequently phase 1 and 2A clinical trials. A potentially more convenient powder formulation may be bridged into phase 2 clinical studies once initial efficacy has been established.

 

The formulation development has been performed at the Aridis facility. Once a clinical scale process is developed, then it will be transferred to the manufacturing facility where clinical scale formulation (drug product) will be produced under GMP manufacturing conditions.

 

Preclinical Safety Testing
 Non-GLP Studies
 Liquid and dry powder formulations were subjected to in vitro bacterial killing tests and acute mouse protection studies (5) to ensure that Panaecin has retained full activity. The minimum inhibitory concentration (MIC) and time to kill (TTK) were calculated for a representative sample of P.aeruginosa including both clinical isolates and standard laboratory strains. MIC and TTK will be determined for other lung pathogens including S. aureus, B. cepacia, H. influenza, S. pneumonia, Stenotrophomonas maltophilia and Klebsiella pneumonia. Panaecin has been tested in a non-GLP rat intratracheal instillation study to determine the deposition in the lung and the half-life of the residence time in the lung. The data displayed in Fig 3 indicates a half-life of 2-3 days for gallium in the lung.

extensive literature on the toxicology of systemic and oral administration, the FDA indicated that inhalation toxicology studies in two animal species will be required to initiate clinical testing of inhaled formulations. Several laboratories were identified with expertise in performing GLP inhalation toxicology studies in rats and dogs, and Huntingdon Life Sciences (East Milstone, NJ) has been selected. The study design mimics the administration of gallium in the proposed phase 1 and 2A clinical studies where gallium will be administered for up to 14 days. Expanded, longer duration toxicology studies are planned to support future clinical trials.

 

Maximum Tolerated Dose (MTD) Studies in Rats. MTD studies will be conducted in rats to determine the highest dose that can be safely administered to animals under routine exposure conditions. The MTD studies will be single dose administrations followed by blood collection at multiple time points to determine systemic levels of compound from tidal breathing animal exposures. Depending on the observed response of rats, after a washout period of 2 days, the exposure concentration will be increased or decreased for subsequent exposures for up to a maximum of 4 treatments to identify the maximum tolerated inhaled dose. In phase 2, rats will be exposed for 7 days to confirm the maximum tolerated or maximum practical dose. The following evaluations will be performed: twice daily viability and clinical observations, physical examinations at pretest, 2 hours after exposure and weekly thereafter, body weights, complete macroscopic examination and histology of entire respiratory tract will be performed on all animals 14-days after exposure.

 

14 Day Inhalation Toxicology Studies in Rats. These will be the definitive GLP toxicology studies. 10 male and 10 female animals per dose with four doses (low, mid, high, control; 80 total). For toxicokinetic analysis 3 male and 3 female animals will be used for the control group (6 total) and 9 male and 9 female animals will be used for each dose group (54 total). Evaluations will be as described above and will also include food consumption, ophthalmology examinations, and hematology, coagulation, clinical chemistry and urinalysis on day 14. Samples for toxicokinetic analyses will be collected on days 1 and 14 at 6 time points with 3 animals/sex/dose/timepoint being evaluated. 0.5 mL of blood will be collected at each time point and the sample processed and stored frozen until analysis. Microscopic examination of a complete tissue set (including up to 4 gross lesions) will be performed on all main study animals in the control and high dose groups (low and mid dose groups available, if needed) and examination of the respiratory tract and lymphoid tissues (including up to 4 gross lesions) will be performed on all main study animals in the low and mid-dose groups.

 

Maximum Tolerated Dose (MTD) Studies in Dogs. MTD studies will be conducted in dogs (purebred Beagles, 8 to 9 Months Old, 1 male and 1 female per group, 4 animals total) to determine the highest dose that can be safely delivered to animals under routine exposure conditions. Animals will be exposed by facemask or oro-pharyngeal administration (1 hr/day for mask or up to 10 min/day for OP) at each target dose. Dosing will proceed as described for MTD study in rats. In phase 2, an additional 1 male and 1 female dog will be exposed to confirm the maximum tolerated or maximum practical dose during a 7 day treatment period. Evaluations will be as described above for MTD in rats with the addition of a qualitative electrocardiogram at pretest and days 1 and 7, and samples will be collected for toxicokinetic evaluations on days 1 and 7 at 6 timepoints per occasion.

 

14 Day Inhalation Toxicology Studies in Dogs. These will be the definitive GLP toxicology studies with a similar design to the 14 day inhalation study in rats. This study will use purebred beagles (9 months old) with 3 males and 3 females at each dose group (low, mid, high, control; 24 total). Toxicokinetic samples will be collected from all animals on days 1 and 14 at 6 timepoints per day. Evaluations will be as described for 14 day inhalation study in rats.

Subsequently, a phase 2A clinical trial in cystic fibrosis patients will be conducted to establish safety and antimicrobial activity of inhaled gallium in the target population. A multicenter, 3 month phase 2B trial will expand the number of CF patients treated and the duration of treatment prior to the pivotal phase 3 trial. More detailed clinical trial designs for each clinical testing phase have been prepared with the input of Aridis’ Clinical Advisory Board.
