In the ASTRAL-1, ASTRAL-2 and ASTRAL-3 studies, 1,035 treatment-naïve and treatment-experienced patients with genotype 1-6 HCV infection, without cirrhosis or with compensated cirrhosis, received 12 weeks of Epclusa. Ninety-eight percent (1,015/1,035) of patients achieved SVR12. In the ASTRAL-5 study, 106 treatment-naïve and treatment-experienced patients with genotype 1-6 HCV infection, without cirrhosis or with compensated cirrhosis, who were coinfected with HIV and on a stable antiretroviral therapy, received 12 weeks of Epclusa. Ninety-five percent (101/106) of patients achieved SVR12.
The ASTRAL-4 study assessed the safety and efficacy of 12 weeks of Epclusa with or without RBV or 24 weeks of Epclusa in 267 HCV-infected patients with genotypes 1-4 and 6 decompensated cirrhosis (Child-Pugh B). Patients with decompensated cirrhosis receiving Epclusa with RBV for 12 weeks achieved 94 percent (82/87) SVR12.
The most common adverse reactions (≥10 percent) experienced by patients treated with Epclusa in ASTRAL-1, ASTRAL-2, ASTRAL-3 and ASTRAL-5 were headache and fatigue. The placebo-treated patients in the ASTRAL-1 experienced headache and fatigue at a similar frequency. The most common adverse reactions (≥10 percent) experienced by HCV-infected patients with decompensated cirrhosis treated with Epclusa and RBV in ASTRAL-4 were fatigue, anemia, nausea, headache, diarrhea and insomnia. Four patients treated with Epclusa with RBV, discontinued treatment due to adverse events.

IMPORTANT SAFETY INFORMATION AND INDICATION FOR EPCLUSA IN U.S.
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 EPCLUSA. 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.
If EPCLUSA is used in combination with ribavirin (RBV), all contraindications, warnings and precautions, in particular pregnancy avoidance, and adverse reactions to RBV also apply. Refer to RBV prescribing information.
Warnings and Precautions
Serious Symptomatic Bradycardia When Coadministered with Amiodarone: Amiodarone is not recommended for use with EPCLUSA 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 EPCLUSA with P-gp Inducers and/or Moderate to Potent Inducers of CYP2B6, CYP2C8 or CYP3A4: Rifampin, St. John’s wort, and carbamazepine are not recommended for use with EPCLUSA as they may significantly decrease sofosbuvir and/or velpatasvir plasma concentrations.
The most common adverse reactions (≥10%, all grades) with EPCLUSA were headache and fatigue; and when used with RBV in decompensated cirrhosis were fatigue, anemia, nausea, headache, insomnia, and diarrhea.
Coadministration of EPCLUSA is not recommended with topotecan due to increased concentrations of topotecan.
Coadministration of EPCLUSA is not recommended with proton-pump inhibitors, oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifapentine, efavirenz, and tipranavir/ritonavir due to decreased concentrations of sofosbuvir and/or velpatasvir.
Consult the full Prescribing Information for EPCLUSA for more information on potentially significant drug interactions, including clinical comments.
EPCLUSA is indicated for the treatment of adults with chronic hepatitis C virus (HCV) genotype 1, 2, 3, 4, 5, or 6 infection without cirrhosis or with compensated cirrhosis and in combination with ribavirin for those with decompensated cirrhosis.
