"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 PromiseSM 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 (Free ASCO Whitepaper) 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.

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
o
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.

About Pamrevlumab

Pamrevlumab is a potential first-in-class antibody being developed by FibroGen to inhibit the activity of connective tissue growth factor (CTGF). Pamrevlumab is in Phase 3 clinical development for the treatment of locally advanced unresectable pancreatic cancer (LAPC) and in Phase 2/3 for the treatment of metastatic pancreatic cancer. The U.S. Food and Drug Administration has granted Orphan Drug Designation, and Fast Track designation to pamrevlumab for the treatment of patients with LAPC. Pamrevlumab has demonstrated a safety and tolerability profile that has supported ongoing clinical investigation in LAPC and metastatic pancreatic cancer. Pamrevlumab is an investigational drug and not approved for marketing by any regulatory authority. For information about our pamrevlumab studies please visit www.clinicaltrials.gov.

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.
