FibroGen Reports Fiscal 2016 Financial Results

SAN FRANCISCO, March 01, 2017 -- FibroGen, Inc. (NASDAQ:FGEN), a science-based biopharmaceutical company, today reported financial results for the year ended December 31, 2016, and provided an update on the company’s recent developments.

“We are pleased with the topline results reported from our two China Phase 3 trials, which are the first Phase 3 readouts for roxadustat, and bring us closer to completing our new drug application submission in China. With our partners AstraZeneca and Astellas, we are making steady progress in Phase 3 clinical development worldwide for roxadustat in CKD anemia, and continue to expect filing of our U.S. NDA in 2018,” said Thomas B. Neff, FibroGen’s Chief Executive Officer. “This year, we are expanding development activities for roxadustat into oncology-related anemias. We are also anticipating important clinical milestones for pamrevlumab, or FG-3019. We began the year with the presentation and publication of promising clinical results in pancreatic cancer, and expect to report data from our placebo-controlled Phase 2 trial in idiopathic pulmonary fibrosis in the third quarter of this year.”

Recent Developments
U.S. and Europe Roxadustat (FG-4592) Anemia in Chronic Kidney Disease (CKD)

• Met initial target enrollment for three FibroGen-sponsored Phase 3 trials supporting U.S. and EU approvals and are continuing to enroll patients to meet overall enrollment goals among the partners
• The independent data safety monitoring board (DSMB), which reviews the U.S. and European Phase 3 program quarterly, recommended in February that trials continue without modification to current protocols

China Roxadustat Anemia in Chronic Kidney Disease

• Completed the controlled portion of our two Phase 3 trials in 2016
• These studies met their primary endpoints for the treatment of anemia in non-dialysis and dialysis patients
  -- In non-dialysis patients, roxadustat achieved a significantly greater increase in mean Hb and a significantly greater Hb response rate, as compared to patients in the placebo arm
  -- In dialysis patients, roxadustat met the predefined non-inferiority criteria for the primary efficacy endpoint. In the pre-specified sequential analysis, roxadustat was also shown to be superior to 利血宝^® (Li Xue Bao) epoetin alfa (Kirin EPO) in mean Hb increase

Japan Roxadustat Anemia in Chronic Kidney Disease

• All six Phase 3 trials are now underway
• Presented Phase 2 study results in non-dialysis-dependent patients in a clinical late-breaker session of the November 2016 American Society of Nephrology (ASN) Kidney Week

U.S. Roxadustat Oncology-Related Anemias

• Phase 3 investigational new drug application was approved by the FDA for the treatment of anemia in myelodysplastic syndromes (MDS) in the fourth quarter of 2016

China Roxadustat Oncology-Related Anemias

• Submitted a clinical trial application (CTA), which is under review by the China Food and Drug Administration (CFDA), for a Phase 2/3 clinical study of anemia in MDS

Pamrevlumab in Idiopathic Pulmonary Fibrosis (IPF)

• Completed enrollment of the Phase 2 double-blind, placebo-controlled -067 study
• Results from Study -049 were published in the European Respiratory Journal, accompanied by an editorial, and the corresponding open-label extension results were presented at the 19th International Colloquium on Lung and Airway Fibrosis (ICLAF)
  -- No safety issues reported with long-term treatment
  -- Trend towards improved or stable pulmonary function and stable fibrosis continued in second year of treatment

Pamrevlumab in Pancreatic Cancer

• Presented findings at the 2017 Gastrointestinal Cancers Symposium (ASCO-GI) from an ongoing open-label, randomized Phase 1/2 study in locally advanced pancreatic cancer -069 showing improvement in survival among patients in the combination arm, as compared to chemotherapy alone
• Published Phase 1/2 trial results in the Journal of Cancer Clinical Trials reporting statistically significant dose-related increase in survival and that pamrevlumab can be safely combined with chemotherapy standard-of-care in advanced pancreatic cancer

Corporate and Financial Highlights

• Net loss per basic and diluted share for the year ended December 31, 2016 was $0.98, as compared to $1.42 a year ago
• At December 31, 2016, FibroGen had $342.2 million of cash, restricted time deposits, cash equivalents, investments, and receivables

Outlook

• Report pamrevlumab topline Phase 2 IPF data, placebo-controlled and combination treatment sub-study results, in the third quarter
• Submit new drug application in China in the third quarter
• Expect to complete enrollment of pamrevlumab open-label, randomized Phase 2 trial in locally advanced pancreatic cancer patients in the first half of the year, and to complete the patient treatment period by year-end
• On track to submit the NDA for roxadustat in the U.S. in 2018

About Roxadustat
Roxadustat (FG-4592) is a first-in-class, orally administered small molecule currently in global Phase 3 clinical development as a potential 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 Phase 3 studies, with target enrollment of about 10,000 patients worldwide, are currently being conducted to support independent regulatory approvals of roxadustat in both NDD-CKD and DD-CKD patients in the U.S., Europe, Japan, and China. Roxadustat is also entering a Phase 3 clinical trial in the U.S. for treatment of anemia in patients with myelodysplastic syndrome (MDS). In China, a roxadustat MDS Phase 2/3 clinical trial application (CTA) is currently under review by the China Food and Drug Administration (CFDA). For information about roxadustat studies currently recruiting patients, please visit www.clinicaltrials.gov.

About Pamrevlumab
Pamrevlumab (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. Studies in a transgenic mouse model of pancreatic cancer indicate that treatment with pamrevlumab in combination with chemotherapy may enhance the efficacy of chemotherapy and improve survival. For information about roxadustat studies currently recruiting patients, please visit www.clinicaltrials.gov.
