SAN FRANCISCO, May 09, 2022 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) today reported financial results for the first quarter 2022 and provided an update on the company’s recent developments.

“We continue our progress in advancing pamrevlumab in three high value indications and are delighted to have completed enrollment of the ZEPHYRUS-1 Phase 3 study in idiopathic pulmonary fibrosis,” said Enrique Conterno, Chief Executive Officer, FibroGen. “In addition, roxadustat is off to a strong start in 2022 in China with significant year over year volume growth.”

Recent Developments:

• Completed enrollment of the ZEPHYRUS-1 Phase 3 clinical trial of pamrevlumab in patients with idiopathic pulmonary fibrosis (IPF).
• Completed enrollment of the LELANTOS-1 Phase 3 clinical trial of pamrevlumab in non-ambulatory patients with Duchenne muscular dystrophy (DMD).
• Our partner Astellas received approval for roxadustat in Russia for the treatment of adult patients with symptomatic anemia associated with chronic kidney disease (CKD), which triggered a $25 million milestone payable to FibroGen.
  

China Performance:

• FibroGen’s net product revenue under U.S. GAAP from sale of roxadustat in China was $18.9 million compared to $15.4 million in the first quarter of 2021. Increase driven mainly due to release of deferred revenue.
• First quarter total roxadustat net sales in China¹ by FibroGen and the distribution entity (JDE) jointly owned by FibroGen and AstraZeneca was $43.5 million, flat as compared to the first quarter of 2021. This result was driven by an increase in volume of over 70% offset by the recent National Reimbursement Drug List (NRDL) price reduction.
• Roxadustat continues to be the number one brand based on value share in the anemia of CKD market in China.
  

Upcoming Milestones:

• Interim analysis of event free survival of the LAPIS Phase 3 study of pamrevlumab in locally advanced pancreatic cancer (LAPC) to be conducted in 2Q 2022.
• Topline data from the LELANTOS-1 Phase 3 study of pamrevlumab in DMD expected 1H 2023.
• Expect to complete enrollment in the LELANTOS-2 Phase 3 study of pamrevlumab in ambulatory patients with DMD in 2Q 2022.
• Topline data from the ZEPHYRUS-1 Phase 3 study of pamrevlumab in IPF expected mid-2023.

• Total revenue for the first quarter of 2022 was $60.8 million, as compared to $38.4 million for the first quarter of 2021.
• Net loss for the first quarter of 2022 was $63.2 million, or $0.68 net loss per basic and diluted share, compared to a net loss of $71.8 million, or $0.78 net loss per basic and diluted share one year ago.
