AASLD 2014: ACH-3102 plus Sofosbuvir Cures All Hepatitis C Patients in Phase 2 Study

Achillion's second-generation HCV NS5A inhibitor ACH-3102 combined with sofosbuvir (Sovaldi) was well-tolerated and led to sustained virological response in all treatment-naive genotype 1 hepatitis C patients in a Phase 2 proxy study, according to late-breaking findings presented at the American Association for the Study of Liver Diseases (AASLD) Liver Meetinglast month in Boston. Another early study showed promising results for Achillion's nucleotide polymerase inhibitor ACH-3422.
