A Study of TCD601 in the Induction of Tolerance in Renal Transplantation (PANORAMA)

February 4, 2026 updated by: ITB-Med LLC

An Adaptive, Regimen Finding, Safety and Tolerability Study of TCD601 (Siplizumab), a Human Anti-CD2 Antibody, Combined With Donor Bone Marrow Cell Infusion and Non-myeloablative Conditioning, for Tolerance Induction in Living Donor Renal Transplantation

The purpose of this study is to determine the optimal regimen for the use of siplizumab, a human anti-CD2 antibody, combined with donor bone marrow cells and non-myeloablative conditioning, for tolerance induction in living donor renal transplantation
