Results from the open-label, Phase 3 ASTRAL-5 study (PS104), led by David L. Wyles, MD, Associate Professor of Medicine, Division of Infectious Diseases, University of California, San Diego, California, evaluating once-daily SOF/VEL for 12 weeks among patients with HCV genotype 1-6 who are co-infected with HIV demonstrated that SOF/VEL was well-tolerated and resulted in high SVR12 rates. The SVR12 rate was 95 percent (n=99/104) overall, and 100 percent (n=19/19) and 97 percent (n=28/29) in patients with cirrhosis and prior treatment-failure, respectively. Two patients relapsed, while three patients were lost to follow up or withdrew consent. Two patients achieved SVR4 but have not yet returned for the post-treatment week 12 visit. The most common adverse events (>10 percent) were fatigue and headache.

A late-breaker oral presentation (PS021) featuring data from a Phase 2 trial, led by Dr. Lawitz, evaluated 12 weeks of a fixed-dose combination of SOF/VEL/GS-9857, with or without RBV, among genotype 1, DAA-experienced, HCV-infected patients, including patients with cirrhosis. One hundred percent (n=24/24) of patients receiving 12 weeks of therapy with SOF/VEL/GS-9857 and 96 percent (n=24/25) of patients receiving SOF/VEL/GS-9857 plus RBV achieved SVR12. Among the 49 patients in this trial, 41 percent had prior exposure to an NS5A inhibitor and 47 percent previously received at least two classes of DAA. The most common adverse events (>10 percent) across both treatment arms were fatigue and anemia.
Studies 1168 and 1169
Studies 1168 and 1169 evaluated 6 and 8 weeks of SOF/VEL plus GS-9857, with or without ribavirin (RBV), among treatment-naïve patients and 12 weeks of SOF/VEL plus GS-9857 among patients who failed prior treatment including those previously exposed to a direct acting antiviral (DAA) regimen. Study 1168 evaluated 197 genotype 1 patients and Study 1169 evaluated 128 genotype 2-6 patients.
Treatment-naïve patients: Poster SAT-138 highlighted combined safety and efficacy results from Studies 1168 and 1169 evaluating SOF/VEL plus GS-9857, with or without ribavirin, in genotype 1-6, treatment-naïve patients, with and without cirrhosis. SVR12 rates were:
SOF/VEL plus GS-9857 6 weeks: 79% (n=53/67) SOF/VEL plus GS-9857 8 weeks: 96% (n=95/99)
SOF/VEL plus GS-9857 with RBV: 8 weeks 81% (n=25/31)
The most common adverse events (>10 percent) across the three study arms were headache, nausea, fatigue, diarrhea and anemia.
Treatment-experienced patients: Oral presentation PS008 highlighted combined safety and efficacy results from Studies 1168 and 1169 evaluating 12 weeks of SOF/VEL plus GS-9857 in genotype 1-6, treatment-experienced patients. Twenty-seven percent of patients were NS5A inhibitor-experienced, 52 percent were non-NS5A inhibitor, DAA-experienced and 21 percent failed interferon-based treatment without a DAA. Overall, the SVR12 rate was 99 percent (n=127/128). One genotype 3 patient with cirrhosis who had failed prior treatment with sofosbuvir plus pegylated interferon/ribavirin relapsed. Frequently reported adverse events (>10 percent) were headache, fatigue, diarrhea and nausea.
