SAN FRANCISCO, May 06, 2024 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ:FGEN) today reported financial results for the first quarter 2024 and provided an update on the company's recent developments.

"We are off to a strong start in 2024 marked by the recent release of compelling Phase 1 data on FG-3246, our CD46 targeted antibody drug conjugate, in metastatic castration-resistant prostate cancer and continued robust growth of our roxadustat business in China," said Thane Wettig, Chief Executive Officer, FibroGen. "Looking ahead, we expect to report topline data from our two late-stage clinical trials of pamrevlumab in pancreatic cancer in the coming months. In addition, we have a strong balance sheet and reaffirm our cash runway into 2026."

Upcoming Milestones:

Pamrevlumab

Topline data from the PanCAN Precision Promise^SM Phase 2/3 study of pamrevlumab in metastatic pancreatic cancer expected in mid-2024, reflecting PanCAN's updated timing to complete database lock and subsequent analysis of the topline results by the independent Statistical Monitoring Committee.
Topline data from the LAPIS Phase 3 study of pamrevlumab in locally advanced unresectable pancreatic cancer (LAPC) expected in 3Q 2024, due to the current trend in reported blinded overall survival events needed to complete the study.

Roxadustat

Expect approval decision for roxadustat in chemotherapy-induced anemia (CIA) in China in the second half of 2024. If approved, FibroGen will receive a $10 million milestone payment from AstraZeneca.

Oncology Pipeline

Initial data from Phase 1 investigator-initiated combination study of FG-3246 with enzalutamide in metastatic castration-resistant prostate cancer (mCRPC) to be presented at ASCO 2024.
Anticipate initiation of Phase 2 monotherapy dose optimization study of FG-3246 in mCRPC in 2H 2024.
Anticipate filing of an IND for FG-3175 (anti-CCR8 mAb) in 2025.

Recent Developments:

Oncology Pipeline

Additional data from a total of 56 biomarker unselected and heavily pre-treated patients in a Phase 1 monotherapy study of FG-3246 in mCRPC reported.
- Efficacy analysis (includes adenocarcinoma patients receiving doses ≥ 1.2 mg/kg):
  - The median radiographic progression free survival (rPFS) in this patient population was 8.7 months.
  - For RECIST evaluable patients, 20% met the criteria of a partial response, or measurable tumor reduction in size of ≥ 30%, with a median duration of response of 7.5 months.
  - PSA reductions of ≥ 50% were observed in 36% of PSA evaluable patients.
- Safety analysis:
  - The most frequent adverse events were consistent with other MMAE-based antibody drug conjugates and included infusion-related reactions, fatigue, weight loss, neutropenia, and peripheral neuropathy.

China:

First quarter FibroGen net product revenue under U.S. GAAP from the sale of roxadustat in China was $30.5 million compared to $24.2 million in the first quarter of 2023, an increase of 26% year over year.
First quarter total roxadustat net sales in China¹ by FibroGen and the distribution entity jointly owned by FibroGen and AstraZeneca (JDE) was $79.4 million, compared to $64.1 million in the first quarter of 2023, an increase of 24% year over year, driven by a 39% increase in volume.
Roxadustat continues to be the number one brand based on value share in the anemia of CKD market in China.
For 2024, we reiterate FibroGen's full year net product revenue under U.S. GAAP to range between $120 million to $135 million, representing full year roxadustat net sales in China¹ by FibroGen and the JDE to range between $300 million to $340 million.

Financial:

Total revenue for the first quarter of 2024 was $55.9 million, as compared to $36.2 million for the first quarter of 2023, an increase of 55% year over year. Total revenue increase was driven by net product revenue in China and one-time drug product revenue of $25.7 million recognized due to the termination of US/RoW AstraZeneca agreement.
Net loss for the first quarter of 2024 was $32.9 million, or $0.33 net loss per basic and diluted share, compared to a net loss of $76.7 million, or $0.81 net loss per basic and diluted share one year ago.
At March 31, 2024, FibroGen reported $214.7 million in cash - defined as cash, cash equivalents, investments, and accounts receivable.
We expect our cash, cash equivalents, investments, and accounts receivable to be sufficient to fund our operating plans into 2026.
