U.S. Important Safety Information and Indications for Vosevi
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
Risk of Hepatic Decompensation/Failure in Patients with Evidence of Advanced Liver Disease: Post-marketing cases of hepatic decompensation/failure, some fatal, have been reported in patients treated with HCV NS3/4A protease inhibitor-containing regimens, including Vosevi. Reported cases occurred in patients with baseline cirrhosis with and without moderate or severe liver impairment (Child-Pugh B or C). In patients with compensated cirrhosis (Child-Pugh A) or evidence of advanced liver disease such as portal hypertension, perform hepatic laboratory testing as clinically indicated; and monitor for signs and symptoms of hepatic decompensation such as the presence of jaundice, ascites, hepatic encephalopathy, and variceal hemorrhage. Discontinue Vosevi in patients who develop evidence of hepatic decompensation/failure. Vosevi is not recommended in patients with moderate to severe hepatic impairment or those with any history of prior hepatic decompensation/failure.
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) observed with treatment with VOSEVI for 12 weeks 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.
Consult the full Prescribing Information for Vosevi for more information on potentially significant drug interactions, including clinical comments.
Vosevi is indicated for the treatment of chronic hepatitis C virus (HCV) infection in adults without cirrhosis or with compensated cirrhosis who have failed prior treatment with an HCV direct-acting antiviral (DAA) who have:
- genotype 1, 2, 3, 4, 5, or 6 infection and have previously been treated with an HCV regimen containing an NS5A inhibitor
- genotype 1a or 3 infection and have previously been treated with an HCV regimen containing sofosbuvir without an NS5A inhibitor
