Abstract

Objective: Direct-acting antivirals for the treatment of hepatitis C virus (HCV) represented a paradigm shift. In 2017, sofosbuvir/velpatasvir (SOF/VEL-Epclusa®) was approved, which showed a high cure rate in all patient, contributing to HCV elimination. The analysis aimed to quantify the clinical and economic value of SOF/VEL in HCV chronic patients since its approval in Spain.

Methods: An economic evaluation was elaborated adapting a Markov model that simulated the lifetime disease progression in of all HCV chronic patients treated with SOF/VEL (30,488 patients) since its launch (5-years), compared to previous therapies. Patients entered the model and were distributed between the fibrosis states (F0-to-F4) in treated and untreated. All patients (100%) were treated with SOF/VEL regardless of their fibrosis, and 49% with previous therapies in ≥F2. The average sustained viral response (SVR) rates 98.9% SOF/VEL versus 61.0% previous therapies. All parameters for the analysis were obtained from real-life data and literature. Only direct healthcare costs associated with disease management were included. The SOF/VEL value was measured as the number of hepatic complications avoided and their associated cost, and hepatic mortality compared to previous therapies. National Health System perspective and a 3% discount rate was applied.

Results: SOF/VEL decreased the number of liver complications, avoiding 92% decompensated cirrhosis, 80% hepatocellular carcinomas, and 87% liver transplants, as well as 85% liver-related mortality. Their cost associated was reduced, amounting to savings of 197Meuro.

Conclusion: SOF/VEL adds relevant value to the HCV treatment, reducing the clinical and economic disease burden and contributing to HCV elimination in Spain.
