Voxilaprevir is a pan-genotypic hepatitis C virus (HCV) non-structural 3/4A (NS3/4A) serine protease inhibitor.1 It inhibits replication of wild-type HCV genotypes 1a, 1b, 2a, 2b, 3a, 4a, 5a, and 6a (EC50s = 1.9-6.6 nM in replicon assays). Voxilaprevir also inhibits replication of mutant HCV genotypes containing NS3 resistance-associated substitutions (EC50s = 3.1, 2.7, and 4 nM for HCV genotypes 1a Q80K, 1a R155K, and 1b D168E, respectively). Formulations containing voxilaprevir have been used in the treatment of chronic HCV infection.

Sofosbuvir, Velpatasvir, and Voxilaprevir for Previously Treated HCV Infection
N Engl J Med 2017 Jun 1;376(22):2134-2146.PMID:28564569DOI:10.1056/NEJMoa1613512.
Background: Patients who are chronically infected with hepatitis C virus (HCV) and who do not have a sustained virologic response after treatment with regimens containing direct-acting antiviral agents (DAAs) have limited retreatment options. Methods: We conducted two phase 3 trials involving patients who had been previously treated with a DAA-containing regimen. In POLARIS-1, patients with HCV genotype 1 infection who had previously received a regimen containing an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive either the nucleotide polymerase inhibitor sofosbuvir, the NS5A inhibitor velpatasvir, and the protease inhibitor Voxilaprevir (150 patients) or matching placebo (150 patients) once daily for 12 weeks. Patients who were infected with HCV of other genotypes (114 patients) were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. In POLARIS-4, patients with HCV genotype 1, 2, or 3 infection who had previously received a DAA regimen but not an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive sofosbuvir-velpatasvir-voxilaprevir (163 patients) or sofosbuvir-velpatasvir (151 patients) for 12 weeks. An additional 19 patients with HCV genotype 4 infection were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. Results: In the three active-treatment groups, 46% of the patients had compensated cirrhosis. In POLARIS-1, the rate of sustained virologic response was 96% with sofosbuvir-velpatasvir-voxilaprevir, as compared with 0% with placebo. In POLARIS-4, the rate of response was 98% with sofosbuvir-velpatasvir-voxilaprevir and 90% with sofosbuvir-velpatasvir. The most common adverse events were headache, fatigue, diarrhea, and nausea. In the active-treatment groups in both trials, the percentage of patients who discontinued treatment owing to adverse events was 1% or lower. Conclusions: Sofosbuvir-velpatasvir-voxilaprevir taken for 12 weeks provided high rates of sustained virologic response among patients across HCV genotypes in whom treatment with a DAA regimen had previously failed.

Profile of sofosbuvir/velpatasvir/Voxilaprevir in the treatment of hepatitis C
Infect Drug Resist 2019 Jul 23;12:2259-2268.PMID:31413603DOI:10.2147/IDR.S171338.
The treatment of chronic hepatitis C has been revolutionized with the introduction of direct-acting antivirals (DAAs). However, some patients are not cured with first-line treatment. Sofosbuvir/velpatasvir/Voxilaprevir is a fixed-dose combination of a polymerase inhibitor, an NS5A inhibitor, and a protease inhibitor with activity against strains of the hepatitis C virus that show resistance to other first-line antiviral regimens. Sofosbuvir/velpatasvir/Voxilaprevir has been studied in four Phase III randomized trials: POLARIS-1, -2, -3, and -4, which enrolled both treatment naïve and experienced patients with and without compensated cirrhosis. In these trials, at least 95% of patients treated with sofosbuvir/velpatasvir/Voxilaprevir achieved sustained virological response (SVR). This includes favorable treatment outcomes in patients who had previously failed a regimen containing sofosbuvir or an NS5A inhibitor. Patient-reported outcomes also improved during and after treatment with sofosbuvir/velpatasvir/Voxilaprevir. Treatment with sofosbuvir/velpatasvir/Voxilaprevir is well tolerated, with the most commonly reported adverse events being headache, fatigue, diarrhea, and nausea. The approval of sofosbuvir/velpatasvir/Voxilaprevir allows a treatment option for patients who have failed treatment with certain DAA regimens.
Sofosbuvir/Velpatasvir/Voxilaprevir: A Pan-Genotypic Direct-Acting Antiviral Combination for Hepatitis C
Ann Pharmacother 2018 Apr;52(4):352-363.PMID:29115151DOI:10.1177/1060028017741508.
Objectives: To review the efficacy and safety of sofosbuvir/velpatasvir/Voxilaprevir in the treatment of hepatitis C virus (HCV) infection. Data sources: A literature search through PubMed was conducted (August 2010 to August 2017) using the terms GS-9857, Voxilaprevir, and NS3/4A protease inhibitor. Study selection/data extraction: Studies of sofosbuvir/velpatasvir/Voxilaprevir were identified. Data synthesis: Sofosbuvir/velpatasvir/Voxilaprevir is indicated for adult patients with chronic HCV without cirrhosis or with compensated cirrhosis who have (1) genotype 1 through 6 and have previously been treated with an NS5A inhibitor or (2) genotype 1a or 3 and have previously been treated with sofosbuvir without an NS5A inhibitor. POLARIS-1 demonstrated that sofosbuvir/velpatasvir/Voxilaprevir for 12 weeks was highly effective in patients with HCV genotype 1 through 6 who had prior exposure to an NS5A inhibitor. POLARIS-2 failed to demonstrate that sofosbuvir/velpatasvir/Voxilaprevir for 8 weeks was noninferior to sofosbuvir/velpatasvir for 12 weeks in patients with HCV genotype 1 through 6 who had no prior exposure to direct-acting antivirals (DAAs). POLARIS-3 demonstrated that sofosbuvir/velpatasvir/Voxilaprevir for 8 weeks was as effective as sofosbuvir/velpatasvir for 12 weeks in patients with HCV genotype 3 and compensated cirrhosis who had no prior exposure to DAAs. POLARIS-4 demonstrated that sofosbuvir/velpatasvir/Voxilaprevir was as effective as sofosbuvir/velpatasvir for 12 weeks in patients with HCV genotype 1 through 3 who had prior exposure to DAAs but not an NS5A inhibitor. The most common adverse reactions were headache, fatigue, diarrhea, and nausea. Conclusions: Sofosbuvir/velpatasvir/Voxilaprevir is safe and effective to treat HCV in patients who have previously been treated with DAAs.
Sofosbuvir/Velpatasvir/Voxilaprevir: A Review in Chronic Hepatitis C
Drugs 2018 Apr;78(5):577-587.PMID:29546556DOI:10.1007/s40265-018-0895-5.
A fixed-dose combination of the hepatitis C virus (HCV) NS5B polymerase inhibitor sofosbuvir, the HCV NS5A inhibitor velpatasvir and the HCV NS3/4A protease inhibitor Voxilaprevir (sofosbuvir/velpatasvir/Voxilaprevir; Vosevi®) is approved in the EU for the treatment of chronic HCV genotype 1, 2, 3, 4, 5 or 6 infection in adults. In the phase III POLARIS trials, in patients who had HCV genotype 1-6 infection with or without compensated cirrhosis, overall rates of sustained virological response at 12 weeks post-treatment (SVR12) with sofosbuvir/velpatasvir/Voxilaprevir were high after 8 weeks of treatment in direct-acting antiviral (DAA)-naïve patients and 12 weeks of treatment in DAA-experienced patients. However, 8 weeks of sofosbuvir/velpatasvir/Voxilaprevir was inferior to 12 weeks of sofosbuvir/velpatasvir in cirrhotic or non-cirrhotic DAA-naïve patients with HCV genotype 1, 2, 4, 5 or 6 infection and non-cirrhotic DAA-naïve patients with HCV genotype 3 infection, mostly due to an insufficient treatment period. Sofosbuvir/velpatasvir/Voxilaprevir was generally well tolerated, with most adverse events being of mild or moderate intensity. The most common adverse events included headache, fatigue, nausea and diarrhoea. In conclusion, sofosbuvir/velpatasvir/Voxilaprevir is an important and effective option for the treatment of HCV genotype 1-6 infection in adults, especially those who have previously failed a DAA therapy with or without an HCV NS5A inhibitor.
Sofosbuvir/velpatasvir/Voxilaprevir: a highly effective option for retreatment of hepatitis C in difficult-to-treat patients
Antivir Ther 2019;24(1):1-10.PMID:30210057DOI:10.3851/IMP3264.
Treatment for hepatitis C has escalated rapidly since the advent of direct-acting antivirals. Although there are highly efficacious, pangenotypic regimens available as standard of care, 5-10% of patients do not achieve virological cure. The recently approved fixed-dose combination of sofosbuvir, velpatasvir and Voxilaprevir provides an option for retreatment in patients who have failed prior regimens and have characteristics which make them difficult to treat. This review provides a summary of the evidence for use of Vosevi®, a fixed-dose combination pill for treatment of hepatitis C in treatment-experienced patients.
