Pamrevlumab Data to be Presented at ATS 2018 and ASCO 2018

Roxadustat U.S. Phase 3 Clinical Studies on Track to Readout in Fourth Quarter 2018

Conference Call Today at 5:00 p.m. Eastern Time/2:00 p.m. Pacific Time

SAN FRANCISCO, May 09, 2018 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN), a science-based biopharmaceutical company, today reported financial results for the first quarter of 2018 and provided an update on the company’s recent developments.

“FibroGen and AstraZeneca are preparing to complete patient enrollment in five Phase 3 roxadustat CKD anemia trials this quarter. We look forward to reporting topline data in the fourth quarter of this year. With our partners, we are continuing to see positive data from our global roxadustat Phase 3 programs, most recently in Japan from Astellas,” said Thomas B. Neff, FibroGen’s Chief Executive Officer. “Pamrevlumab continues to reveal its potential in the treatment of fibrotic and fibro-proliferative diseases. We are working towards achieving regulatory alignment with the FDA on pivotal study designs for both IPF and pancreatic cancer. We will be presenting data at the ATS conference in May from our placebo-controlled Phase 2 study in IPF representing the first known significant attenuation of fibrosis progression as measured by quantitative HRCT, and we will report Phase 2 data at ASCO in June showing that a majority of unresectable locally advanced pancreatic cancer patients treated with pamrevlumab and chemotherapy were assessed as resectable after six months of treatment. We will also report that there appears to be a survival benefit in this study for patients who have undergone tumor resection. Patients continue to be followed in this study for survival.”

Roxadustat for Anemia in CKD in Japan

• Positive topline data from two Phase 3 studies in dialysis-dependent CKD patients with anemia, a long-term ESA conversion study and an ESA-naïve correction study, were reported in April 2018 by our partner Astellas
• Astellas expects to submit a NDA for anemia associated with dialysis-dependent-CKD in Japan in 2018
• Astellas expects data readout in one of the Japan Phase 3 studies in non-dialysis-dependent CKD anemia patients in the fourth quarter of 2018

Corporate and Financial

• Net loss for the first quarter was $41.4 million, or ($0.50) per share, compared to $30.6 million, or ($0.48) per share, for the first quarter of 2017, primarily due to ongoing investments in our research and development and general and administrative initiatives

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 blood cells, 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 State Drug Administration, or SDA (formerly the China Food and Drug Administration, or CFDA). In the U.S., data readout for the Phase 3 program is expected in the fourth quarter of 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 multiple Phase 2 clinical studies, with a good safety and tolerability profile. For information about pamrevlumab studies currently recruiting patients, please visit www.clinicaltrials.gov.
