MK-3682 + grazoprevir + elbasvir or MK-3682 + grazoprevir + MK-8408 There are two triplet therapies and at least one doublet regimen in development by Merck (Kenilworth, NJ) that include MK-3682 (a novel NS5b nucleotide polymerase inhibitor) with or without grazoprevir and with either elbasvir or MK-8408 (a novel NS5A inhibitor). MK-3682 was tested in 300 mg and 450 mg doses in the CREST 1 (for genotypes 1 and 2) and CREST 2 (for genotype 3) studies. The CREST 1 study showed mITT SVR24 of 91–100% for genotypes 1 (n = 93 with 46 GT1a and 47 GT1b) with either elbasvir or MK-8408 at both doses for MK-3682. However, only the MK-3682 (450 mg)/grazoprevir/MK-8408 regimen showed efficacy >90% in genotype 2 patients (n = 61). For genotype 3 patients, both the 300 mg and 450 mg doses of MK-3682 showed SVR24 rates >90% (n = 86).....
