Lessons Learned: Early Termination of a Randomized Trial of Calcineurin Inhibitor and Corticosteroid Avoidance Using Belatacept.

ABSTRACT: The intent of this National Institutes of Health-sponsored study was to compare a belatacept-based immunosuppressive regimen with a maintenance regimen of tacrolimus and mycophenolate. Nineteen primary, Epstein-Barr virus-immune renal transplant recipients with a negative cross-match were randomized to one of three groups. All patient groups received perioperative steroids and maintenance mycophenolate mofetil. Patients in groups 1 and 2 were induced with alemtuzumab and maintained on tacrolimus or belatacept, respectively. Patients in group 3 were induced with basiliximab, received 3 mo of tacrolimus, and maintained on belatacept. There was one death with a functioning allograft due to endocarditis (group 1). There were three graft losses due to vascular thrombosis (all group 2) and one graft loss due to glomerular disease (group 1). Biopsy-proven acute cellular rejection was more frequent in the belatacept-treated groups, with 10 treated episodes in seven participants compared with one episode in group 1; however, estimated GFR was similar between groups at week 52. There were no episodes of posttransplant lymphoproliferative disorder or opportunistic infections in any group. Protocol enrollment was halted prematurely because of a high rate of serious adverse events. Such negative outcomes pose challenges to clinical investigators, who ultimately must weigh the risks and benefits in randomized trials.

Project description:Background and objectivesImmunosuppressive therapy in kidney transplantation is associated with numerous toxicities. CD28-mediated T-cell costimulation blockade using belatacept may reduce long-term nephrotoxicity, compared with calcineurin inhibitor-based immunosuppression. The efficacy and safety of simultaneous calcineurin inhibitor avoidance and rapid steroid withdrawal were tested in a randomized, prospective, multicenter study.Design, setting, participants, & measurementsThis study reports the 2-year results of a randomized clinical trial of 316 recipients of a new kidney transplant. All kidney transplants were performed using rapid steroid withdrawal immunosuppression. Recipients were randomized in a 1:1:1 ratio to receive belatacept with alemtuzumab induction, belatacept with rabbit anti-thymocyte globulin (rATG) induction, or tacrolimus with rATG induction. The composite end point consisted of death, kidney allograft loss, or an eGFR of <45 ml/min per 1.73 m2 at 2 years.ResultsThe composite end point was observed for 11 of 107 (10%) participants assigned to belatacept/alemtuzumab, 13 of 104 (13%) participants assigned to belatacept/rATG, and 21 of 105 (21%) participants assigned to tacrolimus/rATG (for belatacept/alemtuzumab versus tacrolimus/rATG, P=0.99; for belatacept/rATG versus tacrolimus/rATG, P=0.66). Patient and graft survival rates were similar between all groups. An eGFR of <45 ml/min per 1.73 m2 was observed for nine of 107 (8%) participants assigned to belatacept/alemtuzuab, eight of 104 (8%) participants assigned to belatacept/rATG, and 20 of 105 (19%) participants assigned to tacrolimus/rATG (P<0.05 for each belatacept group versus tacrolimus/rATG). Biopsy sample-proven acute rejection was observed for 20 of 107 (19%) participants assigned to belatacept/alemtuzuab, 26 of 104 (25%) participants assigned to belatacept/rATG, and seven of 105 (7%) participants assigned to tacrolimus/rATG (for belatacept/alemtuzumab versus tacrolimus/rATG, P=0.006; for belatacept/rATG versus tacrolimus/rATG, P<0.001). Gastrointestinal and neurologic adverse events were less frequent with belatacept versus calcineurin-based immunosuppression.ConclusionsOverall 2-year outcomes were similar when comparing maintenance immunosuppression using belatacept versus tacrolimus, and each protocol involved rapid steroid withdrawal. The incidence of an eGFR of <45 ml/min per 1.73 m2 was significantly lower with belatacept compared with tacrolimus, but the incidence of biopsy sample-proven acute rejection significantly higher.Clinical trial registry name and registration numberBelatacept Early Steroid Withdrawal Trial, NCT01729494.
