Conference Call and Webcast to be Held Today at 5:00 p.m. Eastern Time/2:00 p.m. Pacific Time

SAN FRANCISCO, Feb. 27, 2018 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN), a science-based biopharmaceutical company, today reported financial results for the fourth quarter and full year 2017 and provided an update on the company’s recent developments.

“In 2017, we continued to make significant progress on key clinical and regulatory milestones. Our first NDA submission for roxadustat was accepted for review by the China Food and Drug Administration. With our partners, we are advancing the roxadustat Phase 3 CKD anemia programs to completion with plans to file for market approvals in the U.S., Europe, and Japan. In our fibrosis program, pamrevlumab has demonstrated tremendous potential in multiple indications. In a randomized double-blind, placebo-controlled Phase 2b study in IPF, pamrevlumab was well-tolerated and achieved statistical significance in the primary endpoint of FVC % predicted, in FVC, and in the secondary endpoints of quantitative changes of lung fibrosis, disease progression, and patient-reported outcomes,” said Thomas B. Neff, FibroGen’s Chief Executive Officer. “We are intensely focused on the execution of critical activities for our CKD anemia, idiopathic pulmonary fibrosis, and pancreatic cancer programs as these approach important new milestones in 2018.”

About Roxadustat
Roxadustat is a first-in-class oral therapeutic in global Phase 3 clinical development as a treatment for anemia associated with chronic kidney disease (CKD) with the potential to offer a safer and more effective, convenient, and accessible treatment than current therapies. Roxadustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), promotes erythropoiesis, or the production of red bloods, by increasing endogenous erythropoietin, improving iron regulation, and reducing hepcidin, including in the presence of inflammation and without need for supplemental intravenous iron.

The roxadustat Phase 3 program is the largest Phase 3 clinical program in anemia to date, and is supported by extensive Phase 2 results demonstrating correction and maintenance of hemoglobin levels in anemia in multiple subpopulations of CKD dialysis and non-dialysis patients. A New Drug Application (NDA) has been accepted for review by the China Food and Drug Administration (CFDA), and enrollment completion and data readout for the Phase 3 program are expected in 2018. Roxadustat is also in Phase 3 clinical development in the U.S. and Europe, and expected to shortly enter Phase 2/3 development in China, for anemia associated with myelodysplastic syndromes (MDS). For information about roxadustat studies currently recruiting patients, please visit www.clinicaltrials.gov.

About Pamrevlumab
Pamrevlumab is a first-in-class antibody developed by FibroGen to inhibit the activity of connective tissue growth factor (CTGF), a common factor in fibrotic and proliferative disorders characterized by persistent and excessive scarring that can lead to organ dysfunction and failure. Pamrevlumab is advancing towards Phase 3 clinical development for the treatment of idiopathic pulmonary fibrosis (IPF) and pancreatic cancer, and is currently in a Phase 2 trial for Duchenne muscular dystrophy (DMD). Pamrevlumab has been well tolerated in a number of Phase 2 clinical studies to date, with a good safety and tolerability profile. For information about pamrevlumab studies currently recruiting patients, please visit www.clinicaltrials.gov.
