FibroGen宣布与FDA的C型会议获得积极反馈，支持推进Roxadustat治疗LR-NHL和高红细胞输血负担患者的贫血

• FibroGen has reached agreement with the FDA on important design elements for a pivotal Phase 3 clinical trial for roxadustat for the treatment of anemia in patients with lower-risk myelodysplastic syndromes (LR-MDS) and high red blood cell (RBC) transfusion burden
• Company intends to file the Phase 3 protocol in the fourth quarter of 2025

SAN FRANCISCO, Aug. 07, 2025 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN) today announced positive feedback from its Type C meeting with the FDA, supporting the advancement of roxadustat for the treatment of anemia in patients with LR-MDS and high RBC transfusion burden, based on a post-hoc subgroup analysis from the MATTERHORN Phase 3 trial.

FibroGen requested the Type C meeting based on the findings of a post-hoc analysis of data from the Phase 3 MATTERHORN trial of roxadustat in anemia-associated with LR-MDS. In patients with high RBC transfusion burden at baseline (≥4 units over 8 weeks1), a pronounced treatment effect was observed: 36% (8/22) of patients achieved transfusion independence (TI) for ≥ 56 days on roxadustat vs 7% (1/15) of patients on placebo within 28 weeks (nominal p-value of 0.041).

The planned Phase 3 trial will assess the safety and efficacy of roxadustat in a randomized, double-blind, placebo-controlled design in approximately 200 patients with LR-MDS. Alignment was reached with the FDA on the patient population (patients requiring ≥ 4 pRBC units in two consecutive 8-week periods prior to randomization, who are refractory to, intolerant to, or ineligible for prior erythropoiesis-stimulating agents (ESA) therapy), dose regimen, as well as management of potential thrombotic risk through eligibility and dose modification and discontinuation criteria. As the primary endpoint for the study, the Company is considering either 8-week or 16-week RBC TI.

FibroGen plans to submit the full Phase 3 protocol to the FDA in the fourth quarter of 2025.
