U.S. Food and Drug Administration Approves Gilead’s Vosevi™ (Sofosbuvir/Velpatasvir/Voxilaprevir) for Re-Treatment of Adults with Chronic Hepatitis C Virus
- Vosevi is the First Once-daily Single-Tablet HCV Regimen Approved as Salvage Therapy for Certain Patients and Completes Gilead’s Portfolio of Sofosbuvir-based HCV Direct-acting Antiviral (DAA) Treatments -
“Direct-acting antiviral regimens have transformed HCV treatment and
have allowed health care providers the fortunate opportunity to cure
many patients. However, for patients who require re-treatment, there
remains an unmet clinical need for an effective and well-tolerated
Vosevi has a boxed warning in its product label regarding the risk of hepatitis B virus (HBV) reactivation in HCV/HBV coinfected patients. See below for important safety information.
Vosevi is the latest single-tablet regimen in Gilead’s portfolio of sofosbuvir-based DAA treatments that offer people living with HCV a short course of therapy to cure their HCV, with the convenience associated with once-daily single-tablet regimens. Since 2013, Gilead has brought to market four HCV treatments, including 3 single-table regimens. To date, more than an estimated 1.4 million patients worldwide have been treated with sofosbuvir-based regimens.
“The evolution of Gilead’s portfolio of HCV single-tablet regimens has
been driven by our commitment to address previously unmet needs and put
the possibility of cure within reach for as many HCV patient populations
as possible,” said
The approval of Vosevi is supported by data from the POLARIS-1 study evaluating 12 weeks of treatment among adults with HCV genotype 1, 2, 3, 4, 5 or 6 with or without compensated cirrhosis who had failed prior treatment with an NS5A inhibitor-containing regimen, as well as data from the POLARIS-4 study evaluating 12 weeks of treatment among adults with HCV genotypes 1a and 3 with or without compensated cirrhosis who had failed prior treatment with a sofosbuvir-containing regimen that did not include an NS5A inhibitor. In these populations across the two studies, 340 of the 353 patients treated with Vosevi (96 percent) achieved the primary endpoint of SVR12, defined as maintaining undetectable viral load 12 weeks after completing therapy.
The most common adverse events (≥10% of patients) among patients who received Vosevi were headache, fatigue, diarrhea and nausea. The proportion of subjects who permanently discontinued treatment due to adverse events was 0.2% for subjects who received Vosevi for 12 weeks.

IMPORTANT SAFETY INFORMATION
BOXED WARNING: RISK OF HEPATITIS B VIRUS REACTIVATION IN HCV/HBV COINFECTED PATIENTS
Test all patients for evidence of current or prior hepatitis B virus (HBV) infection before initiating treatment with Vosevi. HBV reactivation has been reported in HCV/HBV coinfected patients who were undergoing or had completed treatment with HCV direct acting antivirals (DAAs) and were not receiving HBV antiviral therapy. Some cases have resulted in fulminant hepatitis, hepatic failure, and death. Cases have been reported in patients who are HBsAg positive, in patients with serologic evidence of resolved HBV, and also in patients receiving certain immunosuppressant or chemotherapeutic agents; the risk of HBV reactivation associated with treatment with HCV DAAs may be increased in patients taking these other agents. Monitor HCV/HBV coinfected patients for hepatitis flare or HBV reactivation during HCV treatment and post-treatment follow-up. Initiate appropriate patient management for HBV infection as clinically indicated.
- Vosevi is contraindicated with rifampin.
Warnings and Precautions
- Serious Symptomatic Bradycardia When Coadministered with Amiodarone: Amiodarone is not recommended for use with Vosevi due to the risk of symptomatic bradycardia, particularly in patients also taking beta blockers or with underlying cardiac comorbidities and/or with advanced liver disease. A fatal cardiac arrest was reported in a patient taking amiodarone who was coadministered a sofosbuvir containing regimen. In patients without alternative, viable treatment options, cardiac monitoring is recommended. Patients should seek immediate medical evaluation if they develop signs or symptoms of bradycardia.
- Risk of Reduced Therapeutic Effect Due to Concomitant Use of Vosevi with P-gp Inducers and/or Moderate to Potent Inducers of CYP2B6, CYP2C8 or CYP3A4: St. John’s wort and carbamazepine are not recommended for use with Vosevi as they may significantly decrease sofosbuvir, velpatasvir, and/or voxilaprevir plasma concentrations.
- The most common adverse reactions (≥10%, all grades) with Vosevi were headache, fatigue, diarrhea, and nausea.
- Coadministration of Vosevi is not recommended with phenytoin, phenobarbital, oxcarbazepine, rifabutin, rifapentine, atazanavir, lopinavir, tipranavir/ritonavir, efavirenz, rosuvastatin, pitavastatin, and cyclosporine due to changes (decreased or increased) in concentrations of sofosbuvir, velpatasvir, voxilaprevir, and/or the other agent.
