SAN FRANCISCO, May 12, 2025 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN) today reported financial results for the first quarter 2025 and provided an update on the company's recent developments.

"We continue to focus on our most important strategic priority of advancing our lead asset, FG-3246, with the initiation of the Phase 2 monotherapy dose optimization study in mCRPC, expected to start in the third quarter of 2025," said Thane Wettig, Chief Executive Officer, FibroGen. "In addition, we have filed a Type C meeting request with the FDA to discuss the potential Phase 3 development program for roxadustat in the treatment of anemia associated with LR-MDS, an indication with significant unmet medical need.

Recent Developments and Key Highlights of First Quarter 2025:

Sale of FibroGen China to AstraZeneca now expected to be for a total consideration of approximately $185 million, representing an enterprise value of $85 million plus estimated net cash held in China at closing of approximately $100 million. The transaction is expected to close in the third quarter of 2025.

About FG-3246

FG-3246 (FOR46) is a potential first-in-class fully human antibody-drug conjugate (ADC), exclusively in-licensed from Fortis Therapeutics, and is being developed by FibroGen for metastatic castration-resistant prostate cancer and potentially other tumor types. FG-3246 binds to an epitope of CD46, a cell receptor target, that induces internalization upon antibody binding, is present at high levels in prostate cancer and other tumor types and demonstrates very limited expression in most normal tissues. FG-3246 is comprised of an anti-CD46 antibody, YS5, linked to the anti-mitotic agent, MMAE, which is a clinically and commercially validated ADC payload. FG-3246 has demonstrated anti-tumor activity in both preclinical and clinical studies.

FG-3246 is currently in an ongoing Phase 1b/2 study being conducted at UCSF as an investigator-sponsored trial to evaluate FG-3246 in combination with enzalutamide. An additional investigator-sponsored radiopharmaceutical marker trial using a zirconium-89 positron emission tomography (PET) tracer for CD46 that utilizes the YS5 antibody is also underway at UCSF. The initiation of the Phase 2 monotherapy dose optimization trial for FG-3246 in metastatic castration-resistant prostate cancer is anticipated in the third quarter of 2025. FG-3246 is an investigational drug and not approved for marketing by any regulatory authority.
