Summary
This study looks back at medical records of 2,000 people with hepatitis C who took an 8-week course of glecaprevir/pibrentasvir (G/P). The goal is to see how safe and effective the treatment is for those also taking prescription or illegal drugs. Researchers will track side effects and liver enzyme changes to better understand real-world risks.
