LIVE-C-Free: Early and Late Treatment of Hepatitis C With Sofosbuvir/Ledipasvir in Liver Transplant Recipients
The predominant remaining questions for post-transplant treatment of Hepatitis C virus (HCV) in the DAA (direct acting anti-virals) era are whether a ribavirin-free regimen is possible and whether pre-emptive treatment is now a potential option to prevent long-term damage to the allograft.
Our aim is to provide answers to these primary questions with our multicenter, prospective, randomized, open-label intent-to-treat phase IV study
