/EIN News/ -- SAN FRANCISCO, Aug. 06, 2024 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) today reported financial results for the second quarter 2024 and provided an update on the company’s recent developments.

“While we are disappointed with the results from the pamrevlumab pancreatic cancer trials, we continue to be very excited about the prospects of FG-3246 and PET46, our CD46 targeted antibody-drug conjugate and companion PET imaging agent. We have released compelling Phase 1 data on FG-3246 as a monotherapy and in combination with enzalutamide in metastatic castration-resistant prostate cancer. In addition, roxadustat continues its strong momentum in China, exceeding $92 million in net sales in the second quarter,” said Thane Wettig, Chief Executive Officer, FibroGen. “Looking ahead, we expect topline data from the Phase 2 portion of the FG-3246 + enzalutamide combination study in mCRPC in the first half of 2025 and plan on initiating our Phase 2 monotherapy study in mCRPC in the first quarter of 2025 with a more focused and streamlined organization. I would like to express my deepest gratitude to our FibroGen colleagues who have dedicated so much of their time and energy for the prospect of bringing much needed therapies to some of the most challenging and deadly diseases affecting humanity.”

Recent Developments and Key Events of Second Quarter 2024:

• Implementing significant cost reduction plan in the U.S.
  • Headcount in the U.S. will be reduced by approximately 75%.
• Focusing R&D investment on FG-3246 and PET46, a first-in-class antibody-drug conjugate and companion PET imaging agent for mCRPC.
• Announced positive interim results from the dose escalation portion of the investigator-sponsored Phase 1b/2 study conducted by the University of California San Francisco of FG-3246 (FOR46), a potential first-in-class anti-CD46 antibody drug conjugate (ADC) with a MMAE-containing payload, in combination with enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC) at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting.
  • The presentation included data from 17 biomarker unselected patients in the dose escalation portion of the trial. Over 70% of the patients in the study received at least two prior ARSIs, which included prior enzalutamide treatment.
  • The primary endpoint was determination of the maximally tolerated dose (MTD) of FG-3246 in combination with enzalutamide. The MTD was established at 2.1 mg/kg ABW, with primary G-CSF prophylaxis, in combination with enzalutamide 160 mg/day. The combination treatment demonstrated an encouraging preliminary estimate of median radiographic progression free survival (rPFS) of 10.2 months with prostate-specific antigen (PSA) declines observed in 71% (12/17) of evaluable patients.
• 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.
• Reported topline results from the pamrevlumab arm of PanCAN Precision Promise Phase 2/3 adaptive platform trial for the treatment of metastatic pancreatic ductal adenocarcinoma (mPDAC), in which the trial did not meet the primary endpoint.
• Reported topline results from the LAPIS Phase 3 study of pamrevlumab in patients with locally advanced, unresectable pancreatic cancer (LAPC), in which the trial did not meet the primary endpoint.
  

Upcoming Milestones:

    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

• Topline results from the Phase 2 portion of the investigator-sponsored Phase 1b/2 study conducted by the University of California San Francisco of FG-3246 in combination with enzalutamide in patients with mCRPC expected in 1H 2025.
• Anticipate initiation of Phase 2 monotherapy dose optimization study of FG-3246 in mCRPC in 1Q 2025.

China:

• Second quarter FibroGen net product revenue under U.S. GAAP from the sale of roxadustat in China was $49.6 million compared to $23.9 million in the first quarter of 2023, an increase of 108% year over year.
• Second quarter total roxadustat net sales in China¹ by FibroGen and the distribution entity jointly owned by FibroGen and AstraZeneca (JDE) was $92.3 million, compared to $76.4 million in the second quarter of 2023, an increase of 21% year over year, driven by a 33% 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, FibroGen’s expected full year net product revenue under U.S. GAAP is raised to a range between $135 million to $150 million, representing expected full year roxadustat net sales in China¹ by FibroGen and the JDE of $320 million to $350 million, due to continued strong performance in China.

Financial:

• Total revenue for the second quarter of 2024 was $50.6 million, as compared to $44.3 million for the second quarter of 2023, an increase of 14% year over year. Total revenue increase was driven by strong performance of roxadustat in China and changes in net product revenue assumptions under U.S. GAAP.
• Net loss for the second quarter of 2024 was $15.5 million, or $0.16 net loss per basic and diluted share, compared to a net loss of $87.7 million, or $0.90 net loss per basic and diluted share one year ago.
• At June 30, 2024, FibroGen reported $147.1 million in cash, cash equivalents and accounts receivable.
• We expect our cash, cash equivalents and accounts receivable to be sufficient to fund our operating plans into 2026.

About Roxadustat
Roxadustat, an oral medication, is the first in a new class of medicines comprising HIF-PH inhibitors that promote erythropoiesis, or red blood cell production, through increased endogenous production of erythropoietin, improved iron absorption and mobilization, and downregulation of hepcidin. Roxadustat is in clinical development for chemotherapy-induced anemia (CIA) and a Supplemental New Drug Application (sNDA) has been accepted by the China Health Authority.

Roxadustat is approved in China, Europe, Japan, and numerous other countries for the treatment of anemia of CKD in adult patients on dialysis (DD) and not on dialysis (NDD). Several other licensing applications for roxadustat have been submitted by partners, Astellas and AstraZeneca, to regulatory authorities across the globe, and are currently under review. Astellas and FibroGen are collaborating on the development and commercialization of roxadustat for the potential treatment of anemia in territories including Japan, Europe, Turkey, Russia, and the Commonwealth of Independent States, the Middle East, and South Africa. AstraZeneca and FibroGen continue to collaborate on the development and commercialization of roxadustat in China.
