FibroGen Granted Orphan Drug Designation for Pamrevlumab in the Treatment of Pancreatic Cancer

SAN FRANCISCO, June 21, 2017 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN), a science-based biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation status to pamrevlumab, the company’s first-in-class antibody, for the treatment of pancreatic cancer.  

“This is an important regulatory milestone for FibroGen, as pamrevlumab continues to show promise in the treatment of pancreatic cancer,” said Tom Neff, Chief Executive Officer of FibroGen. “Phase 2 clinical studies of pamrevlumab have produced initial positive data on median and one-year survival for patients with advanced pancreatic cancer (88% metastatic). An ongoing study in locally advanced non-resectable pancreatic cancer has shown promise in converting pancreatic cancer from non-resectable to surgically viable. In this current open-label Phase 2 randomized trial, we are evaluating pamrevlumab in combination with chemotherapy standard-of-care versus chemotherapy alone. We look forward to sharing results by early next year.”

Orphan Drug Designation qualifies the sponsor for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing, to advance the evaluation and development of products that demonstrate promise for the diagnosis and treatment of rare diseases or conditions. Orphan Drug Designation can also convey up to seven years of marketing exclusivity if the compound receives regulatory approval from the FDA. FibroGen previously received Orphan Drug Designation for pamrevlumab for the treatment of idiopathic pulmonary fibrosis (IPF).

About Pamrevlumab
Pamrevlumab (formerly FG-3019) is an investigational 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, pancreatic cancer, and Duchenne muscular dystrophy (DMD). In desmoplastic or fibrotic cancers, such as pancreatic cancer, CTGF in the extensive fibrous stroma associated with the tumor promotes abnormal proliferation of stromal cells and tumor cells.
