FibroGen has entered into an exclusive license with Fortis Therapeutics for FOR46, a potential first-in-class Phase 1 antibody-drug conjugate (ADC) targeting a novel epitope on CD46.
FOR46 is being developed for the treatment of metastatic castration-resistant prostate cancer (mCRPC) and is being explored for use in other CD46 expressing cancers. As part of the clinical development strategy, FibroGen will continue Fortis Therapeutics’ work to develop a PET-based biomarker utilizing a radiolabeled version of the targeting antibody (PET46) for patient selection.
“The agreement with Fortis Therapeutics bolsters FibroGen’s clinical pipeline in a capital-efficient manner, providing a product candidate with the potential to address a significant unmet medical need in oncology,” said Enrique Conterno, Chief Executive Officer, FibroGen.
“FOR46 is a natural fit with our R&D capabilities and expertise. The flexibility of the agreement gives us the opportunity to clinically develop FOR46, and ultimately acquire it as a Phase 3-ready asset, potentially delivering a therapy that may transform the treatment of patients with mCRPC and other CD46 expressing cancers.”
“We are pleased to partner with the team at FibroGen, who are experienced in advancing novel drug candidates in the clinic for life-threatening diseases,” said Jay Lichter, Ph.D., president and CEO of Fortis and managing partner of Avalon Bioventures. “We believe that FOR46 is a novel and unique antibody drug conjugate therapy that could help patients with prostate cancer and other cancers, where currently approved treatments have failed.”
Under the terms of the agreement, there is no upfront consideration. FibroGen will conduct and fund future research, development, and manufacturing of FOR46 and PET46. During the four-year evaluation period, FibroGen has the option to acquire Fortis Therapeutics for $80 million. In addition, Fortis is eligible to receive up to a total of $200 million based on various regulatory approvals.
