Company Announces Positive Topline Results from Phase 2 Study in IPF

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

SAN FRANCISCO, Aug. 07, 2017 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN), a science-based biopharmaceutical company, today reported financial results for the second quarter of 2017 and announced positive topline results of the company’s Phase 2 randomized, double-blind, placebo-controlled study and two combination sub-studies of pamrevlumab in idiopathic pulmonary fibrosis (IPF). Pamrevlumab is a proprietary anti-connective tissue growth factor (CTGF) antibody being evaluated in fibrotic disease and cancer.

“We are very encouraged by the topline IPF Phase 2 clinical study results that we announced today, in which pamrevlumab-treated patients had a significantly lower rate of decline in lung function, as compared to the placebo-treated patients. In addition, pamrevlumab continued to be well tolerated as a monotherapy in this IPF study, and was well tolerated in combination with pirfenidone and nintedanib,” said Thomas B. Neff, FibroGen’s Chief Executive Officer. “We believe that the promising outcomes of these studies enable us to advance pamrevlumab into Phase 3 clinical development.”

About Pamrevlumab  
Pamrevlumab is a proprietary therapeutic antibody developed by FibroGen to inhibit the activity of connective tissue growth factor (CTGF), a common factor in chronic fibrotic and proliferative disorders characterized by persistent and excessive scarring that can lead to organ dysfunction and failure. FibroGen is currently conducting clinical studies of pamrevlumab in idiopathic pulmonary fibrosis (IPF), pancreatic cancer, and Duchenne muscular dystrophy (DMD). In desmoplastic or fibrotic cancers, such as pancreatic cancer, CTGF promotes abnormal proliferation of stromal cells and tumor cells.

About Roxadustat  
Roxadustat is a first-in-class, orally administered small molecule currently in global Phase 3 clinical development as a therapy for anemia associated with chronic kidney disease (CKD). Roxadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) that promotes erythropoiesis through increasing endogenous erythropoietin, improving iron regulation, and reducing hepcidin. Administration of roxadustat has been shown to induce coordinated erythropoiesis – increasing red blood cell count while maintaining plasma erythropoietin levels within or near normal physiologic range in multiple subpopulations of CKD patients – including in the presence of inflammation and without a need for supplemental intravenous iron. 

Roxadustat is currently advancing through Phase 3 clinical trials worldwide, supported by extensive Phase 2 clinical data demonstrating correction and maintenance of hemoglobin levels in multiple subpopulations of CKD anemia patients. To date, roxadustat has been evaluated in Phase 1 and Phase 2 studies involving more than 1,400 subjects. Globally, a total of 15 studies are currently underway involving a total of more than 11,000 patients. Of these, 15 are Phase 3 pivotal studies comprising 10,400 patients, and are currently being conducted to support independent regulatory approvals of roxadustat in both non-dialysis and dialysis CKD patients in the U.S., Europe, Japan, and China. Later this year, roxadustat will also enter a Phase 3 clinical trial in the U.S., and a Phase 2/3 trial in China, for the treatment of anemia in myelodysplastic syndromes (MDS).
