FOSTER CITY, Calif.–(BUSINESS WIRE)–Gilead Sciences, Inc. (NASDAQ: GILD) announced that the U.S. Food and Drug Administration (FDA) has approved Epclusa® (sofosbuvir 400 mg/velpatasvir 100 mg), the first all-oral, pan-genotypic, single tablet regimen for the treatment of adults with genotype 1-6 chronic hepatitis C virus (HCV) infection. Epclusa is also the first single tablet regimen approved for the treatment of patients with HCV genotype 2 and 3, without the need for ribavirin. Epclusa for 12 weeks was approved in patients without cirrhosis or with compensated cirrhosis (Child-Pugh A), and in combination with ribavirin (RBV) for patients with decompensated cirrhosis (Child-Pugh B or C).
“The approval of Epclusa represents an important step forward in the global effort to control and potentially eliminate HCV as it provides a safe, simple and effective cure for the majority of HCV-infected patients, regardless of genotype,” said Ira Jacobson, MD, Chairman of the Department of Medicine at Mount Sinai Beth Israel, New York City and a principal investigator in the Epclusa clinical trials. “Building on the established backbone of sofosbuvir, Epclusa demonstrated consistently high cure rates across all genotypes, including among patients with genotype 2 and 3, who traditionally have required ribavirin or other multi-pill regimens.”
The FDA granted Epclusa a Priority Review and Breakthrough Therapy designation, which is given to investigational medicines that may offer major advances in treatment over existing options.
Epclusa’s approval is supported by data from four international Phase 3 studies, ASTRAL-1, ASTRAL-2, ASTRAL-3 and ASTRAL-4. In the ASTRAL-1, ASTRAL-2 and ASTRAL-3 studies, 1,035 patients with genotype 1-6 chronic HCV infection, without cirrhosis or with compensated cirrhosis received 12 weeks of Epclusa. The ASTRAL-4 study randomized 267 patients with genotype 1-6 HCV infection, with decompensated cirrhosis (Child-Pugh B), to receive 12 weeks of Epclusa with or without RBV or 24 weeks of Epclusa. The primary endpoint for all studies was SVR12.
Of the 1,035 patients treated with Epclusa for 12 weeks in the ASTRAL-1, ASTRAL-2 and ASTRAL-3 studies, 1,015 (98 percent) achieved SVR12. In ASTRAL-4, patients with decompensated cirrhosis receiving Epclusa with RBV for 12 weeks achieved a high SVR12 rate (94 percent) compared to those who received Epclusa for 12 weeks or 24 weeks (83 percent and 86 percent, respectively).
Headache and fatigue were the most common adverse reactions (≥10 percent) experienced by HCV-infected patients treated with Epclusa in ASTRAL-1, ASTRAL-2 and ASTRAL-3 and occurred at a similar or higher frequency in placebo-treated patients. In the 87 HCV-infected patients with decompensated cirrhosis treated with Epclusa and ribavirin in the ASTRAL-4 study, fatigue, anemia, nausea, headache, insomnia and diarrhea were the most common adverse reactions (≥10 percent). Two and four patients treated with Epclusa and Epclusa with RBV respectively discontinued treatment due to adverse events.
“Today’s approval represents a significant advance for patients with HCV genotypes 2 and 3, who previously required more complex and costly regimens,” said John Milligan, Ph.D., President and Chief Executive Officer of Gilead. “As the first and only pan-genotypic cure for hepatitis C, Epclusa has the potential to eliminate the need for genotype testing, which can be a barrier to treatment in certain resource-constrained settings. We look forward to making Epclusa available to patients around the world as quickly as possible.”
Epclusa should not be administered with ribavirin in patients for whom ribavirin is contraindicated.
