The study group included 104 patients with HCV genotype 1. Twenty-one took 1500 mg of R1626 twice a day along with peginterferon alpha-2a. Thirty-two took 3000 mg of R1626 twice a day along with peginterferon alpha-2a. Thirty-one took 1500 mg of R1626 twice a day along with peginterferon alpha-2a and ribavirin. And 20 took the standard of care treatment of peginterferon alpha-2a with ribavirin.
After four weeks, HCV RNA was undetectable in 29 percent, 69 percent, and 74 percent of patients in the respective study arms, compared to 5 percent of patients receiving the standard of care treatment.
