Belatacept in De Novo Heart Transplantation
Study Details
Study Description
Brief Summary
The purpose of this study is to determine if Belatacept is safe to give to adult heart transplant recipients. Belatacept (NULOJIX) is an anti-rejection medication that is available through a prescription from a doctor. In this research study, belatacept is being used in an investigational manner (not for the purpose that it is approved for).

Detailed Description
Long-term outcomes after heart transplant remain suboptimal with renal failure and cardiac allograft vasculopathy contributing to morbidity and mortality. Belatacept is Food and Drug Administration (FDA) approved for use in kidney transplant recipients on the basis of two randomized controlled trials, which demonstrated important renal sparing benefits, a reduction in de novo donor-specific antibodies (DSA), and improved long-term outcomes. In this study, ten (10) primary heart transplant recipients will receive belatacept in addition to mycophenolate mofetil, corticosteroids, and a tacrolimus tapering regimen.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Belatacept Participants will receive Belatacept along with an upfront tacrolimus taper Participants will also receive mycophenolate mofetil and corticosteroids are part of standard of care after heart transplant and will follow dosing recommendations as per standard clinical practice. |
Drug: Belatacept
Belatacept will be given in the following way - 10mg/kg IV day 1, 5, end of weeks 2, 4, 8, 12 then 5mg/kg every 4 weeks.
Other Names:
Drug: Tacrolimus
Non-experimental: Tacrolimus will be given in the following way - trough level at month 1, 10-12ng/mL; month 2-3, 6-10ng/mL; month 4-6, 4-6ng/mL; months 7-9 taper off.
Other Names:
Drug: Mycophenolate Mofetil
Non-experimental: MMF is part of standard of care after heart transplant and will follow dosing recommendations as per standard clinical practice at 500-1500mg twice a day (BID) (dosed to tolerance and effect).
Other Names:
Drug: Corticosteroid
Non-experimental: CS is part of standard of care after heart transplant and will follow dosing recommendations as per standard clinical practice at a dose no less than 5mg/d.

Outcome Measures
Primary Outcome Measures
- Number of Major Graft-Related Adverse Events [Up to 18 months after transplantation]
Adverse events that will be counted in the total number include: Episodes of acute cellular rejection ≥ 2R/3A, antibody mediated rejection (AMR) ≥ International Society of Heart and Lung Transplantation (ISHLT) AMR 1, hemodynamically compromised rejection, development of cardiac allograft vasculopathy, graft failure occurring ≥ 14 days post-transplant, the need for re-transplant, serious infection requiring inpatient intravenous therapies, post-transplant lymphoproliferative disorder (PTLD), or death.
Secondary Outcome Measures
- Change in Estimated Glomerular Filtration Rate (eGFR) [Baseline and 18 months]
- Percentage of Individuals with Development of De Novo Donor Specific Antibodies (DSA) [18 months]

-
Potential candidates for whom a calcineurin inhibitor other than tacrolimus (Prograf®) is anticipated after transplant. If during the course of the study, a participant is transitioned to another calcineurin inhibitor due to side effects or inability to achieve stable therapeutic trough levels, they may continue in the study at the discretion of the investigator
