This document discusses generic drugs for treating hepatitis C. It notes that generic drugs contain the same active ingredients as brand name drugs but are usually launched after patents expire. While poorest countries are not subject to intellectual property laws leading to higher generic drug prices, factors like production costs are considered in pricing. Studies found generic sofosbuvir, ledipasvir and daclatasvir were safe and effective. The document advises being honest with patients about potential risks and benefits of generics and arguing for better accessibility of hepatitis C treatments.

Editor's Notes
- PegIFN, peginterferon; RBV, ribavirin; TVR, telaprevir. The lessons learned from the phase II telaprevir studies are shown on this slide. First, the optimal duration of telaprevir therapy was found to be 12 weeks, and it appeared that the optimal duration of the peginterferon and ribavirin backbone was 48 weeks. Second, ribavirin was found to be critically important to decrease breakthrough and relapse rates. Finally, activity was demonstrated in null responders, breakthrough patients, and relapsers.
