Article 3. Cooperative Research and Development

3.1

Performance of Research and Development. The research and development activities to be carried out under this CRADA will be performed solely by the Parties identified on the Cover Page unless specifically stated elsewhere in this Agreement. The PIs will be responsible for the scientific and technical conduct of this project on behalf of their employers. Any Collaborator employees who will work at IC facilities will be required to sign an agreement appropriately modified in view of the terms of this CRADA.

All Parties acknowledge and agree that IC may share Collaborator Materials and Collaborator Confidential Information with the NCATS Therapeutic Development Branch’s (TDB) prime contractor or its subcontractors in fulfillment of the CRADA Research Plan. The TDB prime contractor is subject to a Determination of Exceptional Circumstances (35 U.S.C. § 202(a)(ii)) under the Bayh-Dole Act, which obligates it to assign inventions made by its employees to the United States Government. To the extent that subcontractors of the NCATS TDB prime contractor use Collaborator Materials, or Collaborator Background Information and/or Data or any materials or information which is proprietary to the CRADA Collaborator in fulfillment of the CRADA Research Plan, the subcontractor is thereby subject to a Determination of Exceptional Circumstances (35 U.S.C. § 202(a)(ii)) under the Bayh-Dole Act. Accordingly the said subcontractor is obligated to assign inventions made by its employees arising from such use of materials or information which is proprietary to the CRADA Collaborator, Collaborator Materials, Collaboration Background Information and/or Data to the United States Government. For the purposes of this Agreement, such inventions will be considered jointly developed “CRADA Subject Inventions” and will be jointly owned by Collaborator and IC.

3.2

Research Plan. The Parties recognize that the Research Plan describes the collaborative research and development activities they will undertake and that interim research goals set forth in the Research Plan are good faith guidelines. Should events occur that require modification of these goals, then by mutual agreement the Parties can modify them through an amendment, according to Paragraph 13.6.

3.3

Use and Disposition of Collaborator Materials and IC Materials. The Parties agree to use Collaborator Materials and IC Materials only in accordance with the Research Plan, not to transfer these materials to third parties except in accordance with the Research Plan or as approved by the owning or providing Party, and, upon expiration or termination of the CRADA, to dispose of these materials as directed by the owning or providing Party.

3.4

Third-Party Rights in Collaborator’s CRADA Subject Inventions. If Collaborator has received (or will receive) support of any kind from a third party in exchange for rights in any of Collaborator’s CRADA Subject Inventions, Collaborator agrees to ensure that its obligations to the third party are both consistent with Articles 6 through 8 and subordinate to Article 7 of this CRADA.

PHS CRADA	Agreement Ref. No. 2020-12	MODEL ADOPTED June 18, 2009
Page 4 of 26	Confidential	Revised August 1, 2012

3.5

Disclosures to IC. Prior to execution of this CRADA, Collaborator agrees to disclose to IC all instances in which outstanding royalties are due under a PHS license agreement, and in which Collaborator had a PHS license terminated in accordance with 37 C.F.R. § 404.10. These disclosures will be treated as Confidential Information upon request by Collaborator in accordance with Paragraphs 2.4, 8.3, and 8.4.

Article 4. Reports

4.1

Interim Research and Development Reports. The PIs should exchange information quarterly, in writing. This exchange may be accomplished through meeting minutes, annual reports, detailed correspondence (including e-mail), and circulation of draft manuscripts. Additionally, quarterly meeting of the PI’s will be held for the purpose of identifying new CRADA Subject Inventions and putative inventors that may have arisen from the work being conducted under the Research Plan.

4.2

Final Research and Development Reports. The Parties will exchange final reports of their results within forty-five (45) days after the expiration or termination of this CRADA. These reports will set forth the technical progress made; any publications arising from the research; and the existence of invention disclosures of potential CRADA Subject Inventions and/or any corresponding Patent Applications.

4.3

Additional Reports. The Collaborator will be expected to report to the ICD certain FDA milestones it achieves (such as IND filing, Phase 1, 2 and 3 Trials, etc.) and other major business related events. Other major business related events, may include but are not limited to, third party alliances to co-develop the lead compound, change in the development of indication stated in the CRADA Research Plan.

4.4

Fiscal Reports. If Collaborator has agreed to provide funding to IC under this CRADA and upon the request of Collaborator, then concurrent with the exchange of final research and development reports according to Paragraph 4.2, IC will submit to Collaborator a statement of all costs incurred by IC for the CRADA. If the CRADA has been terminated, IC will specify any costs incurred before the date of termination for which IC has not received funds from Collaborator, as well as for all reasonable termination costs including the cost of returning Collaborator property or removal of abandoned Collaborator property, for which Collaborator will be responsible.

Article 5. Staffing, Financial, and Materials Obligations

5.1

IC and Collaborator Contributions. The contributions of any staff, funds, materials, and equipment by the Parties are set forth in Appendix B. The Federal Technology Transfer Act of 1986, 15 U.S.C. § 3710a(d)(1) prohibits IC from providing funds to Collaborator for any research and development activities under this CRADA.

5.2

IC Staffing. No IC employees will devote 100% of their effort or time to the research and development activities under this CRADA. IC will not use funds provided by Collaborator under this CRADA for IC personnel to pay the salary of any permanent IC employee. Although personnel hired by IC using CRADA funds will focus principally on CRADA research and development activities, Collaborator acknowledges that these personnel may nonetheless make contributions to other research and development activities, and the activities will be outside the scope of this CRADA.

5.3

Collaborator Funding. Collaborator acknowledges that Government funds received by Collaborator from an agency of the Department of Health and Human Services may not be used to fund IC under this CRADA. If Collaborator has agreed to provide funds to IC then the payment schedule appears in Appendix B and Collaborator will make payments according to that schedule. If Collaborator fails to make any scheduled payment, IC will not be obligated to perform any of the research and development activities specified herein or to take any other action required by this CRADA until the funds are received. IC will use these funds exclusively for the purposes of this CRADA. Each Party will maintain separate and distinct current accounts, records, and other evidence supporting its financial obligations under this CRADA and, upon written request, will provide the other Party a Fiscal Report according to Paragraph 4.3, which delineates all payments made and all obligated expenses, along with the Final Research Report described in Paragraph 4.2.

5.4

Capital Equipment. Collaborator’s commitment, if any, to provide IC with capital equipment to enable the research and development activities under the Research Plan appears in Appendix B. If Collaborator transfers to IC the capital equipment or provides funds for IC to purchase it, then IC will own the equipment. If Collaborator loans capital equipment to IC for use during the CRADA, Collaborator will be responsible for paying all costs and fees associated with the transport, installation, maintenance, repair, removal, or disposal of the equipment, and IC will not be liable for any damage to the equipment.

Article 6. Intellectual Property

6.1

Ownership of CRADA Subject Inventions, CRADA Data, and CRADA Materials. Subject to the Government license described in Paragraph 7.5, the sharing requirements of Paragraph 8.1, and the regulatory filing requirements of Paragraph 8.2, the producing Party will retain sole ownership of and title to all CRADA Subject Inventions, all copies of CRADA Data, and all CRADA Materials produced solely by its employee(s). The Parties will own jointly all CRADA Subject Inventions invented jointly and all copies of CRADA Data and all CRADA Materials developed jointly.

6.2

Reporting. The Parties will promptly report to each other in writing each CRADA Subject Invention reported by their respective personnel, and any Patent Applications filed thereon, resulting from the research and development activities conducted under this CRADA. Each Party will report all CRADA Subject Inventions to the other Party in sufficient detail to determine inventorship, which will be determined in accordance with U.S. patent law. These reports will be treated as Confidential Information in accordance with Article 8. Formal reports will be made by and to the Patenting and Licensing Offices identified on the Contacts Information Page herein.

PHS CRADA	Agreement Ref. No. 2020-12	MODEL ADOPTED June 18, 2009
Page 6 of 26	Confidential	Revised August 1, 2012

6.3

Filing of Patent Applications. Each Party will make timely decisions regarding the filing of Patent Applications on the CRADA Subject Inventions made solely by its employee(s), and will notify the other Party in advance of filing. Collaborator will have the first opportunity to file a Patent Application on joint CRADA Subject Inventions and will notify PHS of its decision within sixty (60) days of an Invention being reported or at least thirty (30) days before any patent filing deadline, whichever occurs sooner. If Collaborator fails to notify PHS of its decision within that time period or notifies PHS of its decision not to file a Patent Application, then PHS has the right to file a Patent Application on the joint CRADA Subject Invention. Neither Party will be obligated to file a Patent Application. Collaborator will place the following statement in any Patent Application it files on a CRADA Subject Invention: “This invention was created in the performance of a Cooperative Research and Development Agreement with the [INSERT into Agency’s model as appropriate: National Institutes of Health, Food and Drug Administration, Centers for Disease Control and Prevention], an Agency of the Department of Health and Human Services. The Government of the United States has certain rights in this invention.” If either Party files a Patent Application on a joint CRADA Subject Invention, then the filing Party will include a statement within the Patent Application that clearly identifies the Parties and states that the joint CRADA Subject Invention was made under this CRADA.

6.4

Patent Expenses. Unless agreed otherwise, the Party filing a Patent Application will pay all preparation and filing expenses, prosecution fees, issuance fees, post issuance fees, patent maintenance fees, annuities, interference expenses, and attorneys’ fees for that Patent Application and any resulting Patent(s). If a license to any CRADA Subject Invention is granted to Collaborator, then Collaborator will be responsible for all expenses and fees, past and future, in connection with the preparation, filing, prosecution, and maintenance of any Patent Applications and Patents claiming exclusively-licensed CRADA Subject Inventions and will be responsible for a pro-rated share, divided equally among all licensees, of those expenses and fees for non-exclusively licensed CRADA Subject Inventions. Collaborator may waive its exclusive option rights at any time, and incur no subsequent financial obligation for those Patent Application(s) or Patent(s).

6.5

Prosecution of Patent Applications. The Party filing a Patent Application will provide the non-filing Party with a copy of any official communication relating to prosecution of the Patent Application within thirty (30) days of transmission of the communication. Each Party will also provide the other Party with the power to inspect and make copies of all documents retained in the applicable Patent Application or Patent file. The Parties agree to consult with each other regarding the prosecution of Patent Applications directed to joint CRADA Subject Inventions. If Collaborator elects to file and prosecute Patent Applications on joint CRADA Subject Inventions, then Collaborator agrees to use the U.S.P.T.O. Customer Number Practice and/or grant PHS a power(s) of attorney (or equivalent) necessary to assure PHS access to its intellectual property rights in these Patent Applications. PHS and Collaborator will cooperate with each other to obtain necessary signatures on Patent Applications, assignments, or other documents.

Article 7. Licensing

7.1

Background Inventions. Other than as specifically stated in this Article 7, nothing in this CRADA will be construed to grant any rights in one Party’s Background Invention(s) to the other Party, except to the extent necessary for the Parties to conduct the research and development activities described in the Research Plan.

7.2

Collaborator’s License Option to CRADA Subject Inventions. With respect to Government rights to any CRADA Subject Invention made solely by an IC employee(s) or made jointly by an IC employee(s) and a Collaborator employee(s) for which a Patent Application was filed, PHS hereby grants to Collaborator an exclusive option to elect an exclusive or nonexclusive commercialization license. The license will be substantially in the form of the appropriate model PHS license agreement and will fairly reflect the nature of the CRADA Subject Invention, the relative contributions of the Parties to the CRADA Subject Invention and the CRADA, a plan for the development and marketing of the CRADA Subject Invention, the risks incurred by Collaborator, and the costs of subsequent research and development needed to bring the CRADA Subject Invention to the marketplace. The field of use of the license will not exceed the scope of the Research Plan.

7.3

Exercise of Collaborator’s License Option. To exercise the option of Paragraph 7.2 Collaborator must submit a written notice to the PHS Patenting and Licensing Contact identified on the Contacts Information Page (and provide a copy to the IC Contact for CRADA Notices) within three (3) months after either (i) Collaborator receives written notice from PHS that the Patent Application has been filed or (ii) the date on which Collaborator files the Patent Application. The written notice exercising this option will include a completed “Application for License to Public Health Service Inventions” and will initiate a negotiation period that expires nine (9) months after the exercise of the option. If PHS has not responded in writing to the last proposal by Collaborator within this nine (9) month period, the negotiation period will be extended to expire one (1) month after PHS so responds, during which month Collaborator may accept in writing the final license proposal of PHS. In the absence of Collaborator’s exercise of the option, or upon election of a nonexclusive license, PHS will be free to license the CRADA Subject Invention to others. These time periods may be extended at the sole discretion of PHS upon good cause shown in writing by Collaborator.

7.4

Government License in IC Sole CRADA Subject Inventions and Joint CRADA Subject Inventions. Pursuant to 15 U.S.C. § 3710a(b)(1)(A), for CRADA Subject Inventions owned solely by IC or jointly by IC and Collaborator, and licensed pursuant to the option of Paragraph 7.2, Collaborator grants to the Government a nonexclusive, nontransferable, irrevocable, paid-up license to practice the CRADA Subject Invention or have the CRADA Subject Invention practiced throughout the world by or on behalf of the Government. In the exercise of this license, the Government will not publicly disclose trade secrets or commercial or financial information that is privileged or confidential within the meaning of 5 U.S.C. § 552(b)(4) or which would be considered privileged or confidential if it had been obtained from a non-federal party.

7.5

Government License in Collaborator Sole CRADA Subject Inventions. Pursuant to 15 U.S.C. § 3710a(b)(2), for CRADA Subject Inventions made solely by an employee of Collaborator, Collaborator grants to the Government a nonexclusive, nontransferable, irrevocable, paid-up license to practice the CRADA Subject Invention or have the CRADA Subject Invention practiced throughout the world by or on behalf of the Government for research or other Government purposes.

7.6

Third Party License. Pursuant to 15 U.S.C. § 3710a(b)(1)(B), if PHS grants an exclusive license to a CRADA Subject Invention made solely by an IC employee or jointly with a Collaborator employee, the Government will retain the right to require Collaborator to grant to a responsible applicant a nonexclusive, partially exclusive, or exclusive sublicense to use the CRADA Subject Invention in Collaborator’s licensed field of use on terms that are reasonable under the circumstances; or, if Collaborator fails to grant a license, to grant the license itself. The exercise of these rights by the Government will only be in exceptional circumstances and only if the Government determines (i) the action is necessary to meet health or safety needs that are not reasonably satisfied by Collaborator, (ii) the action is necessary to meet requirements for public use specified by federal regulations, and such requirements are not reasonably satisfied by Collaborator; or (iii) Collaborator has failed to comply with an agreement containing provisions described in 15 U.S.C. § 3710a(c)(4)(B). The determination made by the Government under this Paragraph is subject to administrative appeal and judicial review under 35 U.S.C. § 203(b).

7.7

Third-Party Rights In IC Sole CRADA Subject Inventions. For a CRADA Subject Invention conceived prior to the Effective Date solely by an IC employee that is first actually reduced to practice after the Effective Date in the performance of the Research Plan, the option offered to Collaborator in Paragraph 7.2 may be restricted if, before the Effective Date, PHS had filed a Patent Application and has either offered or granted a license or has executed a license in the CRADA Subject Invention to a third party. Collaborator nonetheless retains the right to apply for a license to any such CRADA Subject Invention in accordance with the terms and procedures of 35 U.S.C. § 209 and 37 C.F.R. Part 404.

Article 8. Rights of Access and Publication

CRADA Materials.

Collaborator and IC will use reasonable efforts to keep descriptions of CRADA Materials confidential until published or until corresponding Patent Applications are filed. Collaborator acknowledges that the basic research mission of PHS includes sharing with third parties for further research those research resources made in whole or in part with NIH funding. Consistent with this mission and the tenets articulated in “Sharing of Biomedical Research Resources: Principles and Guidelines for Recipients of NIH Research Grants and Contracts”, December 1999, available at http://www.ott.nih.gov/policy/research_tool.aspx, following publication either Party may make available to third parties for further research those CRADA Materials made jointly by both PHS and Collaborator. Notwithstanding the above, if those joint CRADA Materials are the subject of a pending Patent Application or a Patent, the Parties may agree to restrict distribution or freely distribute them. Either Party may distribute those CRADA Materials made solely by the other Party only upon written consent from that other Party or that other Party’s designee.

8.3

Confidential Information. Each Party agrees to limit its disclosure of Confidential Information to the amount necessary to carry out the Research Plan, and will place a confidentiality notice on all such information. A Party orally disclosing Confidential Information to the other Party will summarize the disclosure in writing and provide it to the other Party within fifteen (15) days of the disclosure. Each Party receiving Confidential Information agrees to use it only for the purposes described in the Research Plan. Either Party may object to the designation of information as Confidential Information by the other Party.

8.4

Protection of Confidential Information. Confidential Information will not be disclosed, copied, reproduced or otherwise made available to any other person or entity without the consent of the owning or providing Party except as required by a court or administrative body of competent jurisdiction, or federal law or regulation. Each Party agrees to use reasonable efforts to maintain the confidentiality of Confidential Information, which will in no instance be less effort than the Party uses to protect its own Confidential Information. Each Party agrees that a Party receiving Confidential Information will not be liable for the disclosure of that portion of the Confidential Information which, after notice to and consultation with the disclosing Party, the receiving Party determines may not be lawfully withheld, provided the disclosing Party has been given a reasonable opportunity to seek a court order to enjoin disclosure.

TITLE OF CRADA: Fast, Centrally-Acting, Non-Addicting Novel Analgesic for Chronic Non-Cancer Pain

PHS [IC] Component:	NCATS
IC Principal Investigator:	Donald Lo, Ph.D.

Collaborator:	Virpax Pharmaceuticals, Inc
Collaborator Principal Investigator:	Jeffrey Gudin, MD
TERM OF CRADA:	Four (4) years from the Effective Date.

ABSTRACT OF THE RESEARCH PLAN:

Americans are faced with a dual crisis of chronic pain and an opioid abuse epidemic. The development of an effective analgesic with rapid onset for the treatment of pain that is devoid of the common side effects that are often associated with the use of the highly prescribed mu-opioid receptor agonists is a priority for our healthcare system. Having such an analgesic with this product profile has the potential to alleviate suffering and reduce dependence on mu-opioid based analgesics which contribute to misuse, abuse, and overdose related deaths due to severe respiratory depression. Another endogenous opioid system, the enkephalins, preferentially bind to delta-opioid receptors and are able to produce analgesic benefit without the associated respiratory depression typically noted from mu-opioid receptor binding, and as an additional benefit, is also thought to play an important role in emotional reactivity and mood disturbance which often accompanies chronic painful disorders. Unfortunately, systemically administered enkephalins are prevented from reaching the brain by both rapid enzymatic degradation and the blood-brain-barrier, even with the use of various penetration enhancers, preventing their development as patient-available pain therapy. This CRADA between the NIH/NCATS and Virpax Pharmaceuticals focuses on the characterization of NES100, a fast, centrally acting, non-addicting analgesic. In the NES100 formulation, the active pharmaceutical ingredient is the endogenous peptide Leu Enkephalin (L-ENK) whose molecules are encapsulated utilizing a proprietary nanoparticle “molecular envelope technology” or MET. The polymer used to make the nanoparticles confers a positive surface charge to the nanoparticles which allows it to stick to and integrate into mucosal surfaces present in the nasal cavity upon intranasal administration. This “mucointegration” is expected to enhance the residence time of the nanoparticulate peptide in the nares, enabling the prolonged delivery of L-ENK. The polymer nanoparticles encapsulating L-ENK is then able to transport L-ENK exclusively to the brain via the intranasal route with essentially no peripheral exposure. The scope of this project plan includes studies that are focused on the pre-clinical characterization of NES100 as a novel analgesic for acute and chronic non-cancer pain.

II. Goal(s) of Project

Goals of the project include:

●

Project Planning / Initiation / CRADA execution

●

Non-cGMP and cGMP manufacture of NES100 (medicinal product and device) and API stability studies

●

Formulation development, fill / finish, and stability studies

●

Development or optimization & qualification and/or validation of new or existing assays and associated analytical methods required for characterization of NES100

●

Bioanalytical assay development and qualification and/or validation

●

Pre-clinical PK studies in species planned for use in efficacy and safety evaluations

●

PK/PD studies in efficacy models in Sprague Dawley rats

●

IND enabling Toxicology and Safety Pharmacology studies

For avoidance of doubt, the scope of the CRADA Research Plan is limited to tasks / studies that are focused on the pre-clinical development of NES100 for the management of acute and chronic, non-cancer pain.

III. Background

Chronic pain is among the most common reasons for seeking medical attention and is reported by 20 - 50%of patients seen in primary care. While the CDC in their 2016 Guidelines (Dowell et al., 2016) recommends initial treatment of non-cancer chronic pain with acetaminophen and NSAIDs, these agents feature black box warnings for serious cardiovascular and gastrointestinal adverse events, and acetaminophen has known hepatotoxicity. Most notably, both classes of analgesics have documented limited efficacy. Opioids are effective, but their associated tolerance, dependence and euphoria has contributed to the current abuse epidemic, and their respiratory depressant actions contribute to significant abuse-related mortality. Development of a fast-acting, highly effective analgesic for the treatment of non-cancer chronic pain that is devoid of the common, well- recognized side effects of opioids which act predominantly at mu (µ)-opioid receptors, is therefore a priority to break the cycle of pain-prescription-dependence-overdose.

Naturally occurring endorphins bind to µ-opioid receptors and act as a key molecular switch, triggering brain reward systems and potentially initiating addictive behaviors. Another endogenous opioid system, i.e. the enkephalins, preferentially bind to delta (δ)-opioid receptors (Toll et al., 1998) to produce analgesic benefits without the associated respiratory depression typically noted from µ-opioid receptor binding. In addition, δ-opioid receptor is thought to play an important role in emotional reactivity and mood disturbance which often accompanies chronic painful disorders. Unfortunately, systemically administered enkephalins are prevented from reaching the brain by both rapid enzymatic degradation and the blood- brain-barrier (BBB) (Lalatsa et al., 2014), even with the use of various penetration enhancers (Lalatsa et al., 2012), preventing their development as patient-available pain therapy. Therefore, new methods of enkephalin delivery must be developed and investigated to devise novel, non-addictive pain-relieving therapies.

NES100 is a microparticulate dosage form of leucine-5- enkephalin (L-ENK) prepared by the encapsulation of L-ENK in an IP-protected molecular envelope technology (MET), aka GCPQ (N-palmitoyl-N-monomethyl-N, N-dimethyl-N, N, N-trimethyl-6-O-glycolchitosan), which is a modified amphiphilic chitosan derivative polymer that self-assembles in aqueous media. The polymer used to make the nanoparticles confers a positive surface charge to the nanoparticles and the particles stick to and integrate into mucosal surfaces present in the nasal cavity. This “mucointegration” is believed to enhance the residence time of the nanoparticulate peptide in the nares, enabling the prolonged delivery of L-ENK. The polymer nanoparticles encapsulating L-ENK is then able to transport L-ENK exclusively to the brain via the intranasal route with essentially no peripheral exposure.

Efficacy studies have shown that NES100 is active in several animal models of acute and chronic pain. The collaboration is focused on investigational new drug (IND) studies and the output of this project will be a data package suitable for an IND application to the US FDA.
