Ombitasvir is a potent inhibitor of the hepatitis C virus protein NS5A, with EC50s of 0.82 to 19.3 pM against HCV genotypes 1 to 5 and 366 pM against genotype 6a. Ombitasvir has EC50s of 14.1 and 5.0 pM against genotype 1a-H77 and 1b-Con1 subgenomic replicons, respectively.
In GT1a, variants M28V, L31V, and H58D confers 58- to 243-fold resistance to Ombitasvir. Single variants M28T, Q30R, and Y93C/S confers 800- to 8965-fold resistance, while Y93H/N confers >40000-fold resistance to Ombitasvir.
