How Does Mavyret Work?

Glecaprevir inhibits the hepatitis C virus NS3/4A protease, preventing processing of viral proteins needed for replication. Pibrentasvir inhibits the viral NS5A protein, interfering with viral RNA replication and assembly. Their combined actions suppress hepatitis C virus reproduction.

Who Is Treated With Mavyret?

Mavyret is used in adults and children age 3 and older with qualifying hepatitis C infections, including selected previously treated patients. Treatment is restricted to patients without cirrhosis or with compensated cirrhosis. Moderate or severe hepatic impairment, any history of hepatic decompensation, and use with atazanavir or rifampin are contraindications.

How Is Mavyret Dosed?

Adults take three tablets together once daily with food, totaling 300 mg glecaprevir and 120 mg pibrentasvir. Children age 12 and older or weighing at least 45 kg generally use the tablet regimen. Younger children weighing less than 45 kg use weight-based oral pellet doses. Treatment-naive patients typically receive eight weeks, while some previously treated patients require 12 or 16 weeks.

What Serious Risks Are Linked to Mavyret?

Mavyret carries a boxed warning for hepatitis B virus reactivation in patients with current or previous hepatitis B infection, including cases of liver failure and death. Severe hepatic decompensation or liver failure has also occurred, particularly in patients with advanced liver disease. Testing for hepatitis B is required before treatment. Drug interactions can also cause serious adverse reactions or reduce antiviral activity.
