Popis: Introduction:Recently developed direct-acting antiviral (DAA) treatments for hepatitis C virus (HCV) are groundbreaking in their high efficacy across disease genotypes and lack of severe side effects. This study used a cost-of-illness (COI) approach to estimate the net value conferred by one of these novel drug combinations, sofosbuvir and velpatasir (SOF/VEL), recently licensed for generic manufacture in India.Methods:This study considered COI from lifetime earnings lost due to disability and premature death from HCV infection. Risk of death and disability in future years was calculated using a Markov state-transition model with parameters determined from the literature. The future earnings of sampled patients were predicted using an empirical earnings model, with coefficients determined from India Human Development Survey data. Costs to both the patient and secondarily infected individuals were considered.Results:Preliminary results suggested that curing individuals diagnosed with chronic HCV in India would preserve INR 3.7 million (USD 55,750) in earnings per person. For non-cirrhotic (NC) and compensated cirrhotic (CC) individuals, the expected benefits associated with preventing secondary infections were worth between one and forty-one percent of the value of benefits conferred to the diagnosed individuals (depending on sex and extent of liver damage). Treating decompensated cirrhotic (DC) individuals with DAAs alone offered minimal earnings benefits because these individuals will likely remain disabled and unable to work without a liver transplant. Expected net benefits of treatment were substantial for NC and CC patients, ranging from INR 640,349 (USD 9,531) for NC women to INR 10.7 million (USD 158,968) for CC men. The cost of treatment for DC individuals exceeded the expected earnings benefits.Conclusions:For average NC and CC individuals, the cost of treatment with SOF/VEL is offset by the benefits of increased future productivity. Increased earnings are not sufficient to offset the cost of treatment for DC individuals, but treatment may still be justified on the basis of the intrinsic value of health improvements and other treatment benefits.
