Washington, D.C Fax Subject: Harvoni Page: 1 of 9 Last Review Date: March 18, 2016 Harvoni Description Harvoni (ledipasvir & sofosbuvir) Background Hepatitis C is a viral disease that causes inflammation of the liver that can lead to diminished liver function or liver failure. Most people infected with hepatitis C virus (HCV) have no symptoms of the disease until liver damage becomes apparent, which may take several years. Some people with chronic HCV infection develop scarring and poor liver function (cirrhosis) over many years, which can lead to complications such as bleeding, jaundice (yellowish eyes or skin), fluid accumulation in the abdomen, infections or liver cancer (1). Harvoni is a combination pill to treat chronic HCV genotype 1 infection that does not require administration with peg-interferon or ribavirin. Both drugs in Harvoni, ledipasvir (an NS5A inhibitor) and sofosbuvir (an NS5B-inhibitor), interfere with the enzymes needed by HCV to multiply. Sofosbuvir is a previously approved HCV drug marketed under the brand name Sovaldi (2). Regulatory Status FDA-approved indications: Harvoni is a fixed-dose combination of ledipasvir, a hepatitis C virus (HCV) NS5A inhibitor, and sofosbuvir, an HCV nucleotide analog NS5B polymerase inhibitor, and is indicated for the treatment of chronic hepatitis C (CHC) genotype 1, 4, 5 and 6 infection in adults (2).

2 Subject: Harvoni Page: 2 of 9 Off Label Uses: In the SOLAR-1 study, a large multicenter, randomized controlled trial that included liver transplant recipients with HCV genotype 1 and 4 with a range of liver disease, including advanced liver disease and decompensated liver function, Harvoni and ribavirin for 12 weeks was found to be efficacious and well-tolerated, with SVR12 rates ranging from 60-98%. Harvoni was recommended per the AASLD/ IDSA guidelines for patients post liver transplant when used in combination with ribavirin (4-5). Harvoni is a two-drug fixed-dose combination product that contains 90 mg of ledipasvir and 400 mg of sofosbuvir in a single tablet. The recommended dosage of Harvoni is one tablet taken orally once daily with or without food (2). Harvoni treatment durations for treatment-naïve (with or without cirrhosis) and treatmentexperienced (without cirrhosis) patients is 12 weeks. The treatment duration for treatmentexperienced patients with cirrhosis is 24 weeks. Treatment-experienced is defined as patients who have failed treatment with either peg-interferon alfa + ribavirin or treatment with the combination of an HCV protease inhibitor + peg-interferon alfa + ribavirin. Harvoni for 8 weeks can be considered in treatment-naïve patients without cirrhosis who have pre-treatment HCV RNA less than 6 million IU/ml (2-3). Based on data from the SIRIUS study, patients with cirrhosis in whom a prior PEG-IFN and RBV, with or without HCV protease inhibitors containing regimen failed may also receive Harvoni plus weight-based RBV for 12 weeks (4). In patients who require retreatment more urgently, based on emerging data and the expected pattern of HCV drug resistance, patients in whom simeprevir plus sofosbuvir does not result in a cure may be treated with ledipasvir/sofosbuvir with or without RBV for 24 weeks (3). No dose recommendation of Harvoni can be given for patients with severe renal impairment (estimated Glomerular Filtration Rate [egfr] <30 ml/min/1.73m 2 ) or with end stage renal disease (ESRD) due to higher exposures (up to 20-fold) of the predominant sofosbuvir metabolite (2). The use of Harvoni with other drugs containing sofosbuvir, including Sovaldi, is not recommended (2). Safety and effectiveness of Harvoni in children less than 18 years of age have not been established (2).
