Background And AimTreatment of hepatitis C virus (HCV) infection with low-cost generic direct-acting antivirals (DAAs) available in India and other developing countries needs determination of HCV genotype ("genotype-dependent" regimens). Generic velpatasvir, a DAA that obviates the need for genotype determination ("pan-genotypic" regimen), recently became available but is costlier. The aim of this study was to evaluate the cost-effectiveness of genotype-dependent versus pan-genotypic DAA treatments in India.MethodsA previously validated microsimulation model, adapted to Indian population, was used to compare the costs and long-term outcomes of three scenarios: no treatment, treatment with genotype-dependent regimens, and treatment with pan-genotypic regimen. Input parameters were derived from literature. Using a payer's perspective and lifetime time horizon, quality-adjusted life-years (QALYs), total costs, and incremental cost-effectiveness ratio were calculated. Both deterministic and probabilistic sensitivity analyses were also conducted.ResultsAt the current price ($US223 for 4 weeks), pan-genotypic regimen was cost-saving compared with no treatment. Compared with genotype-dependent regimens, it increased QALYs by 0.92 and increased costs by $US107 but was deemed cost-effective with an incremental cost-effectiveness ratio of $US242 per QALY gained. Probabilistic sensitivity analysis also supported the cost-effectiveness of pan-genotypic regimen. At the reduced price of $US188 for 4 weeks, the pan-genotypic regimen will become cost-neutral to genotype-dependent regimens (current price: $US100 for 4 weeks).ConclusionsAt current prices, velpatasvir-based pan-genotypic regimen is cost-effective for HCV treatment in India where generic drugs are available. A reduction in the prices of pan-genotypic regimen has the potential to make its use cost-saving while simplifying treatment in community-level programs aimed at HCV elimination.© 2018 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.
