FibroGen Announces Positive Topline Results from China Pivotal Phase 3 Clinical Trial of Roxadustat for the Treatment of Chemotherapy Induced Anemia
- Met primary endpoint of noninferiority of roxadustat to erythropoietin alfa
- Plan to file supplemental New Drug Application in China
SAN FRANCISCO and BEIJING, May 18, 2023 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) and its subsidiary, FibroGen (China) Medical Technology Development Co., Ltd. today announced positive topline data from Company’s Phase 3 clinical study of roxadustat for treatment of anemia in patients receiving concurrent chemotherapy treatment for non-myeloid malignancies in China.
Roxadustat (爱瑞卓®) demonstrated non-inferiority compared to recombinant erythropoietin alfa (SEPO®) on the primary endpoint of change in hemoglobin (Hb) level from baseline to the average level during weeks 9-13.
In the preliminary safety analysis, the adverse event profile of roxadustat was generally consistent with previous findings and supportive of a positive benefit risk in this patient population.
“Roxadustat is a promising potential new oral drug for treating chemotherapy-induced anemia, which complicates the treatment of many cancer patients,” said Mark D. Eisner, MD, MPH, Chief Medical Officer, FibroGen. “Chemotherapy-induced anemia remains an unmet medical need in China, and we believe that roxadustat has potential to improve the lives of these patients.”
A total of one-hundred fifty-nine (159) patients with non-myeloid malignancy (solid tumor) with a baseline hemoglobin level at or below 10 g/dL were enrolled into this Phase 3, randomized, open-label, active-controlled study investigating the efficacy and safety of roxadustat for treatment of chemotherapy-induced anemia (CIA). Patients were randomly assigned roxadustat or erythropoietin alfa three times per week (TIW), during a treatment period of 12 weeks, with an additional 4-week follow-up period. The primary endpoint of the study was change in hemoglobin level from baseline to the average level during weeks 9-13. For more information regarding this study, please visit www.clinicaltrials.gov (NCT05301517).
Detailed results from the study will be submitted for presentation at an upcoming medical conference.
This Phase 3 study is sponsored and conducted by FibroGen and is part of the collaboration with AstraZeneca. FibroGen will work with AstraZeneca and the China Health Authority to file the supplemental New Drug Application.
About Chemotherapy-Induced Anemia
Although chemotherapy-induced anemia is one of the most common side effects of chemotherapy, it is often not recognized and is frequently undertreated. CIA can adversely affect long-term patient outcomes, as anemia limits both quality of life and efficacy of chemotherapy treatment. The incidence and severity of CIA depends on a variety of factors. This includes the type of cancer and the treatment, including the type of chemotherapy, schedule, and intensity of therapy. It also depends on whether the patient has received prior myelosuppressive chemotherapy, radiation therapy, or both. An estimated
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) in China.
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. FibroGen and AstraZeneca are collaborating on the development and commercialization of roxadustat for the potential treatment of anemia in the U.S., China, and other markets not licensed to Astellas.
