Randomized Controlled Trial of Danoprevir Plus Peginterferon Alfa-2a and Ribavirin in Treatment-Naïve Patients With Hepatitis C Virus Genotype 1 Infection

The combination of danoprevir, peginterferon alfa-2a, and ribavirin leads to high rates of SVR in patients with HCV genotype 1 infection, but high doses of danoprevir can lead to grade 4 increases in alanine aminotransferase. Studies of lower doses of danoprevir with ritonavir, to reduce overall danoprevir exposure while maintaining potent antiviral activity, are underway; Clinicaltrials.gov number, NCT00963885.
