Belatacept in Heart Transplantation (NCT06478017)

Belatacept With Delayed Tacrolimus Withdrawal Versus Standard-of-Care Tacrolimus in Heart Transplant Recipients (RTB-013)

🟢 Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)

🩺 Plain-English Summary (8th-Grade Level)

This is a phase 2, prospective, multi-center, open-label clinical trial. Sixty-six (66) primary heart transplant recipients will be randomized (1:2) to receive either standard-of-care, tacrolimus-based immunosuppression, or a belatacept-based regimen with gradual tacrolimus withdrawal over 9-months post-transplant. Both study arms will receive CellCept® (mycophenolate mofetil- MMF) or Myfortic® (mycophenolate sodium). Corticosteroids will be continued throughout the study in the belatacept arm. The primary objective is to evaluate whether NULOJIX® (belatacept), when implemented with gradual tacrolimus withdrawal over 9 months, is safe with respect to preventing the composite endpoint of acute cellular rejection (ACR) \>= International Society of Heart and Lung Transplantation (ISHLT) 2R, hemodynamic compromise rejection in the absence of a biopsy or histological rejection, re-transplantation, and death at 18 months post-transplant.
