Gilead Sciences, Inc. (NASDAQ:GILD) announced that the Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the European Medicines Agency (EMA), has adopted a positive opinion on the company’s Marketing Authorization Application (MAA) for Vosevi®, an investigational, once-daily, single tablet regimen of sofosbuvir 400 mg, velpatasvir 100 mg, and voxilaprevir 100 mg (SOF/VEL/VOX) for the treatment of chronic hepatitis C virus (HCV)-infected patients. The data included in the application support the use of SOF/VEL/VOX in patients with and without compensated cirrhosis, with all genotypes (GT1-6) of HCV infection regardless of prior therapy, including 8 weeks of treatment for HCV direct-acting antiviral (DAA)-naïve patients without cirrhosis, as well as 12 weeks of treatment for patients who have previously failed therapy with a DAA-containing regimen.
The CHMP positive opinion was adopted following an accelerated assessment procedure, reserved for medicinal products expected to be of major public health interest. The recommendation will now be reviewed by the European Commission, which has the authority to approve medicines for use in the 28 countries of the European Union, Norway and Iceland.
The MAA for SOF/VEL/VOX is supported by data from four Phase 3 studies. Two studies (POLARIS-1 and POLARIS-4), evaluated 12 weeks of the single tablet regimen in patients with genotypes 1-6 HCV infection previously treated unsuccessfully with DAA-containing regimens, including NS5A inhibitors. Two other studies (POLARIS-2 and POLARIS-3) evaluated 8 weeks of SOF/VEL/VOX in DAA-naïve patients with genotypes 1-6 HCV infection. Across POLARIS-1 and POLARIS-4, 97 percent of patients treated with SOF/VEL/VOX (n=431/445) achieved the primary efficacy endpoint of SVR12. In POLARIS-2, 95 percent of patients with genotypes 1-6 HCV infection with and without cirrhosis treated with SOF/VEL/VOX (n=477/501) achieved the primary efficacy endpoint of SVR12. In POLARIS-3, 96 percent of patients with genotype 3 infection and cirrhosis treated with SOF/VEL/VOX (n=106/110) achieved the primary efficacy endpoint of SVR12. The most common adverse events among patients who received SOF/VEL/VOX in the POLARIS studies were headache, fatigue, diarrhea and nausea.
