Patient-reported outcomes 12 months after hepatitis C treatment with direct-acting antivirals: Results from the PROP UP study

Background & Aims: The long-term impact of hepatitis C virus (HCV) therapy with all-oral direct-acting antivirals (DAAs) on patient-reported outcomes (PROs) has not been well-described. We characterized changes in PROs from pre-treatment to 12 months post-treatment in a real-world cohort. Methods: PROP UP was a multi-centre observational cohort study of 1601 patients treated with DAAs at 11 US gastroenterology/hepatology practices from 2015 to 2017. PROs were evaluated pre-treatment (T1) and 12 months post-treatment (T5). A minimally important change (MIC) threshold was prespecified as >5% change in PRO scores from T1 to T5. Multivariable analyses identified predictors of change. Results: Three-quarters of patients were 55 or older; 45% were female, 60% were white, 33% were black, nearly half had cirrhosis. The most commonly-prescribed DAA regimens were sofosbuvir-based (83%) and grazoprevir/elbasvir (11%). Study retention was >95%. On average, small improvements were observed at 3 months post-treatment in all PROs and sustained at 12 months post-treatment among patients with sustained virologic response (SVR). Clinically meaningful improvements were achieved in fatigue (mean change score: −3.7 [−4.2, −3.1]), sleep (mean change score: −3.1 [−3.7, −2.5]), abdominal pain (mean change score: −2.6 [−3.3, −1.9]) and functional well-being (mean change score: −7.0 [−6.0, −8.0]). Symptom improvements were generally not sustained with no SVR (n = 52). Patients with cirrhosis and MELD ≥12 had the greatest improvements in functional well-being (−12.9 [−17.6, −8.1]). Conclusions: The improvements in patient-reported outcomes reported by patients who achieved SVR following HCV DAA therapy were durable at 12 months post-treatment.
