Item 1.01 | Entry into a Material Definitive Agreement |
On July 13, 2015, Five Prime Therapeutics, Inc. (FivePrime) entered into a Research Collaboration and License Agreement (the Agreement) with INBRX 110 LP (Inhibrx).
Under the terms of the Agreement, FivePrime obtained (a) an exclusive, worldwide license to antibodies to glucocorticoid-induced tumor necrosis factor receptor (GITR) for therapeutic and diagnostic uses (respectively, Licensed Therapeutic Products and Licensed Diagnostic Products and collectively, the Licensed Products), and (b) an exclusive option (the Option) to obtain exclusive, worldwide licenses to multi-specific antibodies developed by Inhibrx that bind to both GITR and other targets (each, a Multi-Specific Product), which option FivePrime can exercise with respect to a Multi-Specific Product within a limited period of time after (i) certain activities related to initiating clinical manufacturing of such Multi-Specific Compound (the Manufacturing Initiation) or (ii) if not earlier exercised, the dosing of the first patient in a Phase 2 clinical trial of such Multi-Specific Product (Phase 2 Dosing).
Pursuant to the Agreement, FivePrime will make an upfront payment of $10 million to Inhibrx. Additionally, with respect to each Licensed Therapeutic Product, FivePrime will be obligated to pay up to $62.5 million in specified development milestone payments and (i) if such Licensed Therapeutic Product does not receive a Breakthrough Therapy Designation from the U.S. Food and Drug Administration (the FDA), up to $280 million in specified regulatory and commercial milestone payments, or (ii) if such Licensed Therapeutic Product receives a Breakthrough Therapy Designation from the FDA, up to $380 million in specified regulatory and commercial milestone payments.
If FivePrime exercises the Option with respect to a Multi-Specific Product at Manufacturing Initiation, FivePrime would pay Inhibrx $15 million for such Option exercise. If FivePrime exercises the Option with respect to a Multi-Specific Product at Phase 2 Dosing, FivePrime would pay Inhibrx $30 million for such Option exercise. After such Option exercise, such Multi-Specific Product would be treated as a Licensed Therapeutic Product under the Agreement and FivePrime would be obligated to pay the milestone payments specified in the preceding paragraph with respect to such Multi-Specific Product.
FivePrime may pay all or a portion of milestone payments for development and regulatory events in shares of common stock of FivePrime, subject to certain limitations and conditions. FivePrime would be obligated to register for resale under the Securities Act of 1933, as amended, any such shares of common stock of FivePrime.
FivePrime is also obligated to pay Inhibrx (a) with respect to each Licensed Therapeutic Product, tiered low double-digit percentage royalties on net sales of such Licensed Therapeutic Product, subject to reduction in certain circumstances, and (b) with respect to each Licensed Diagnostic Product, low single-digit percentage royalties on net sales of such Licensed Diagnostic Product, in each case, for the longer of (i) 12 years after the first commercial sale of such Licensed Product or (ii) the life of certain patents licensed covering such Licensed Product. FivePrime cannot determine the date on which FivePrimes potential royalty payment obligations to Inhibrx would expire because FivePrime has not yet commercialized any Licensed Products under the Agreement and therefore FivePrime cannot identify the date of the first commercial sale or the expiration dates of any related patents covering such Licensed Products.
Unless earlier terminated by either party, the Agreement will expire on a product-by-product and country-by-country basis upon the expiration of all of FivePrimes payment obligations under the Agreement. FivePrime may terminate the Agreement in its entirety at any time with advance written notice. Either party may terminate the Agreement in its entirety with written notice for the other partys material breach if such party fails to cure the breach. Either party also may terminate the Agreement in its entirety upon certain insolvency events involving the other party.
The foregoing description of the Agreement is only a summary and is qualified in its entirety by reference to the Agreement, a copy of which FivePrime plans to file as an exhibit in a subsequently filed Quarterly Report on Form 10-Q.

Five Prime Therapeutics Establishes Strategic Research Collaboration and License Agreement with Inhibrx for Novel GITR Antibodies
| Inhibrxs technology may offer best-in-class approach for agonist antibodies |
| New program further expands Five Primes immuno-oncology pipeline and potential for combination therapies |
SOUTH SAN FRANCISCO, Calif., and LA JOLLA, Calif., July 15, 2015 (GLOBE NEWSWIRE) Five Prime Therapeutics, Inc. (Nasdaq: FPRX) (Five Prime), a clinical-stage biotechnology company focused on discovering and developing novel protein therapeutics for cancer and inflammatory diseases, today announced a strategic research collaboration and license agreement with Inhibrx for Inhibrxs novel glucocorticoid-induced tumor necrosis factor receptor (GITR) antibody program, which is currently at lead selection stage.
Leveraging its comprehensive protein library and proprietary in vivo screening technologies, Five Prime identified GITR as one of the most potent inhibitors of tumor growth. GITR is an immune checkpoint protein that is selectively expressed on effector T cells and T regulatory cells (Tregs), and is believed to activate an immune response against tumor cells. In preclinical studies, agonist antibodies have demonstrated the ability to induce tumor regressions, particularly when administered in combination with other immuno-oncology therapies.
Inhibrxs technology offers a novel, potentially best-in-class approach for engineering a GITR antibody with the desired properties aimed at maximizing safety, efficacy and combinability with other therapies. Inhibrxs multivalent antibody scaffolds are designed to multimerize and activate GITR independent of Fc binding. This is in contrast to conventional GITR antibodies, where efficacy is dependent upon binding and the presence of Fc-receptor bearing cells and may vary due to Fc receptor polymorphisms and be dampened by competing serum IgG.
Under the terms of the agreement, Five Prime will pay Inhibrx a $10 million license fee in return for exclusive, worldwide therapeutic and diagnostic rights to antibodies provided by Inhibrx that bind to GITR, as well as an option to license multi-specific antibodies that bind to GITR and other targets. Inhibrx is eligible to receive up to $342.5 million in development, regulatory and commercial milestone payments per therapeutic product, or up to $442.5 million in development, regulatory and commercial milestone payments if the U.S. Food and Drug Administration grants a Breakthrough Therapy Designation to such therapeutic product. Milestone payments for development, regulatory and first commercial sale events may be paid in cash or in Five Prime common stock at Five Primes discretion. Inhibrx is also eligible for low double-digit tiered royalties on future product sales.
Five Prime is actively pursuing a comprehensive approach to immuno-oncology by identifying pipeline candidates with the potential to work independently or in combination to target macrophages, immune check points, T cell agonist pathways and Treg cells. Comparing across many potential targets, our platform pointed to GITR as an ideal agonist to expand our portfolio, said Lewis Rusty T. Williams, M.D., Ph.D., chief executive officer & president of Five Prime. Inhibrxs antibody technology is uniquely suited to activate GITR and enhance the immune response against the tumor. We believe this program has the potential to create a differentiated, next-generation GITR agonist that may have broad therapeutic application as a monotherapy or in combination with approved checkpoint inhibitors or other therapies, including products in our pipeline.
We believe Five Primes insights into GITR biology and their scientific and clinical translation capabilities make them the optimal partner for our GITR program, said Mark Lappe, CEO of Inhibrx. They share our commitment to bring therapeutics to patients in need as quickly as possible and we are excited to be collaborating with them.
Five Prime intends to provide updated cash guidance when it reports its second quarter 2015 financial results.
