Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Proportion of subjects who experience acute cellular rejection (ACR) >ISHLT 2R (local or core read), hemodynamic compromise (HDC) rejection in the absence of a biopsy or histological rejection, re-transplantation, or death as a composite endpoint.

Secondary Outcomes (23)

From baseline to 18 months post-transplantation, assessed at Baseline, Randomization, Month 1, 6 and 18
Proportion of subjects with eGFR <60mL/min/1.73m^2 measured by CKD-EPI
From randomization to 18 months post-transplantation
Proportion of subjects with eGFR<45mL/min/1.73m^2 measured by CKD-EPI
From randomization to 18 months post-transplantation
Mean change in albumin/creatinine ratio in urine
From baseline to 18 months post-transplantation
Change in Chronic Kidney Disease (CKD) stage measured using the mean difference on a continuous measurement scale
From Baseline to 18 months post-transplantation, assessed at Baseline, Month 1, 12 and 18
- +18 more secondary outcomes
Study Arms (2)
Belatacept + Tacrolimus withdrawal
EXPERIMENTAL1. Maintenance Immunosuppression: NULOJIX (belatacept) 2. Maintenance Immunosuppression: CellCept (mycophenolate mofetil- MMF), or Myfortic (mycophenolate sodium) 3. Calcineurin Inhibitors (CNI) Taper: Prograf® (tacrolimus), or tacrolimus generic 4. Corticosteroid: Prednisone (no less than 5mg per day continued throughout the study period)

Prograf (tacrolimus) or tacrolimus generic
CellCept (mycophenolate mofetil- MMF), or Myfortic (mycophenolate sodium)
Eligibility Criteria
You may qualify if:
- Study entry
- Subject must be able to understand the purpose of the study and be willing to participate and provide written consent
- Recipient of a primary heart transplant (heart transplant only)
- Epstein-Barr Virus (EBV) seropositive (VCA IgG, EBNA IgG). If EBNA is not available, enrollment may proceed but the result must be available prior to randomization.
- Agreement to use contraception; according to the Food and Drug Administration (FDA) Office of Women's Health (http://www.fda.gov/birthcontrol), there are a number of birth control methods that are more than 80% effective. Female participants of child-bearing potential must consult with their physician and determine the most suitable method(s) from this list to be used for the duration of the study
- In the absence of a contraindication, vaccinations must be up to date per the Division of Allergy, Immunology, and Transplantation (DAIT) Vaccination Guidance for Patients in Transplant Trials (niaidtransplantstudies.org)
- Mechanical support or investigational drug trials where the intervention ends at the time of transplantation are permitted.
- Randomization
- Recipient of a primary heart transplant
- No desensitization therapy prior to transplant
- Negative crossmatch actual or virtual, on the most recent sera as determined by the participating study center
- Female subjects of childbearing potential must have a negative pregnancy test (serum or urine) prior to randomization
- Agreement to use contraception; according to the FDA Office of Women's Health (http://www.fda.gov/birthcontrol), there are a number of birth control methods that are more than 80% effective. Female participants of child-bearing potential must consult with their physician and determine the most suitable method(s) from this list to be used for the duration of the study. Those who choose oral contraception must agree to use a second form of contraception after administration of study drug for a period of 1 year after the last dose of study drug
- Pre-transplant eGFR (CKD-epi) \>30ml/min/1.73m\^2. If eGFR \<30ml/min/1.73m\^2 at the time of randomization, participation is permitted if the study physician determines that renal recovery is expected. Participants who are on dialysis at randomization or are expected to require dialysis at or after randomization will not be permitted to participate.
You may not qualify if:
- Study entry
- Candidate for multiple solid organ or tissue transplants
- Prior history of any organ, tissue, or cellular transplant
- Currently breast-feeding a child or plans to become pregnant during the timeframe of the study follow up period
- History of severe allergic and/or anaphylactic reactions to humanized or murine monoclonal antibodies
- Known hypersensitivity to NULOIX (belatacept) or ORENCIA (Abatacept)

- Patients with active Tuberculosis (TB) in the past 2 years, whether or not it was adequately treated; patients with documented treatment of active TB greater than 2 years ago will be allowed to participate if there is documentation of adequate treatment according to locally accepted clinical practice
- Subjects must be tested for latent TB infection (LTBI) within a year prior to transplant. Testing should be conducted using either a PPD or Interferon-gamma release assay (i.e., QuantiFERON-TB, T-SPOT.TB). Patients with a positive test for latent TB infection (LTBI) must have completed appropriate therapy for LTBI (https://www.cdc.gov/tb/topic/treatment/ltbi.htm). A subject is considered eligible only if they have a negative test for LTBI within one year prior to transplant OR if they have completed appropriate LTBI therapy within one year prior to transplant
- Positive serology for T. cruzi or known/suspected history of Chagas disease
