This is a prospective multi-center, longitudinal study to determine efficacy of 50 percent Immunosuppression (IS) reduction. One hundred fully eligible participants will reduce IS by 50 percent in two steps. Liver tests will be checked every 0.5 months through month 4, once a month through month 12, and every other month through month 18. Liver transplant (LTx) center visits will take place at screening, months 6, 12 and 18 after initiating IS dose reduction. A protocol driven liver biopsy to adjudicate the endpoint will be performed at 18 months. The duration of the study from time of starting IS dose reduction to the primary endpoint assessment is 18 months. The primary objective is to assess the efficacy of 50 percent IS dose reduction in children with Liver transplants (LTxs)
Inclusion Criteria: 1. Participant and parent or guardian must be able to understand and provide informed assent and consent, respectively 2. Recipient of a living or deceased donor Liver transplant (LTx) at \<7 years of age 3. \> 3 years but \<7 years after LTx at the time of study enrollment 4. Stable liver tests defined as baseline serum alanine aminotransferase (ALT) level \< 30 IU/l and gamma-glutamyl transferase (GGT) level \< 50 IU/l (based on the average of the 3 most recent values prior to screening; all must be within 1 year of screening; 2 must be within 6 months of screening) 5.
