Efficacy and Safety of Everolimus Versus Mycophenolate Mofetil in Liver Transplant Recipients.

Multi-center, Open-label, Randomized Controlled Phase 4 Study to Evaluate the Efficacy and Safety of CertiroBell® Compared With Mycophenolate Mofetil in Primary Living Donor Liver Transplant Recipients.

The purpose of this study is to evaluate the efficacy and safety of CertiroBell® tablet compared with mycophenolate mofetil in primary living donor liver transplant recipients.

This study is multi-center, open-label, randomized controlled phase 4 study to evaluate the efficacy and safety of certirobell® tablet compared with mycophenolate mofetil in primary living donor liver transplant recipients.

On the first visit the patients scheduled to be operated liver transplant in 35 days will be conducted screening. Patients who meet the criteria of this clinical trial will be randomized to CertiroBell or mycophenolate mofetil on the second visit. Each group will take CertiroBell or mycophenolate mofetil and will conduct scheduled tests with 5 additional visits.
