The following people have nothing Syk inhibitor to disclose: Zobair Younossi BACKGROUND & AIM: CHC infection has been shown to negatively affect work productivity, creating an economic burden for employers and society. Sofosbuvir and ledipasvir is being developed as an oral single tablet regimen (LDV/SOF) with excellent clinical efficacy and tolerability in CHC genotype 1 (GT1) patients. An economic model was created

to estimate the work productivity outcomes for SOF-containing therapies versus no treatment. METHODS: The analysis modeled a population of GT1 CHC patients across two scenarios: no treatment, and treatment with LDV/SOF. The number of CHC

patients in the workforce was calculated from employment rates among HCV patients (64.1%) and the prevalent GT1 CHC population in the USA, sourced from the literature. Presenteeism and absenteeism were estimated from the Work Productivity and Activity Index: Specific Health Problem questionnaire administered at baseline, week-12 of treatment and post-achievement of SVR-12 from the ION clinical trials. The average hourly wage ($24.29) was sourced from the US Bureau of Labor Statistics, and used to calculate total productivity selleck inhibitor costs of CHC patients. RESULTS: At baseline, the rates of presenteeism and absenteeism among GT1 CHC patients are 8.07 %and 2.72%. Not treating CHC patients is expected to result in $7.4 billion of lost work productivity costs annually. LDV/SOF treatment resulted in 96.7 MCE公司 %of patients achieving an SVR-12 which was associated with an increase in work productivity by 35 %from baseline, an expected economic gain of $2.5 billion per year. These gains (in

Table 1) were only due to improvements in presenteeism 12 weeks after treatment discontinuation. A sensitivity analysis assuming treated patients achieved a 100 %SVR rate resulted in work productivity savings of $2.6 billion per year. Given work productivity data were only captured 12 weeks post-treatment, a sensitivity analysis assuming a 60 %benefit of LDV/SOF over baseline was performed; here, savings were expected to be $4.2 billion per year. CONCLUSIONS: Relative to no treatment, SOF/LDV is estimated to yield significant work productivity improvements in GT1 CHC patients and substantial gains from the societal perspective.
