Abstract
Objectives: To review the pharmacology, efficacy, and safety of daclatasvir in the treatment of patients with chronic hepatitis C virus (HCV) infection. Data Sources: A literature search through EMBASE and PubMed was conducted (January 1966 to August 2015) using the terms BMS-790052, daclatasvir, and hepatitis C. References from retrieved articles were reviewed for any additional material. Additionally, the new drug application and prescribing information were retrieved. Study Selection/Data Extraction: The literature search was limited to human studies published in English. Phase 1, 2, and 3 studies describing the pharmacology, pharmacokinetics, efficacy, and safety of daclatasvir for HCV were identified. Data Synthesis: Daclatasvir, a nonstructural 5A protein inhibitor, combined with sofosbuvir, is indicated for adult patients with chronic HCV genotype 3 regardless of treatment or cirrhosis status. The phase III ALLY-3 trial (n = 152) demonstrated that daclatasvir taken once daily with sofosbuvir for 12 weeks was effective at achieving sustained virological response (SVR) rates in treatment-naïve (97%) and treatment-experienced (94%) patients without cirrhosis. Patients with cirrhosis had significantly lower SVR rates (58 and 69%, respectively). The most common adverse drug events associated with daclatasvir and sofosbuvir in ALLY-3 were headache (20%), fatigue (19%), and nausea (12%). Conclusions: Daclatasvir, when combined with sofosbuvir, is an effective agent to treat HCV genotype 3, with SVR rates above 90% for patients without cirrhosis who are treatment naïve or experienced. SVR rates for treatment-naïve or -experienced patients with cirrhosis are not as robust (58%-69%).
