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 is active against the genotype 2a JFH-1 replicon, with an EC50 of 0.82 pM, and the EC50s of ombitasvir are 42 pM and 68 pM against the L28 and F28 variants of this genotype 6a replicon, respectively[1]. 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[2].
