Pharmacokinetics, Safety and Tolerability of Single-dose Belatacept in Adolescent Kidney Transplant Recipients

A Phase 2 Multi-Center, Randomized Conversion Study to Evaluate the Pharmacokinetics, Efficacy, and Safety of Belatacept Administered to Pediatric Subjects With a Stable Renal Transplant

The purpose of this study is to evaluate how well adolescent kidney transplant patients tolerate a single dose of belatacept they receive at least 6 months after transplant surgery, and how their body handles the drug.
