NCT06478017

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.

    From randomization to 18 months post-transplantation

Secondary Outcomes (23)

  • Slope of estimated glomerular filtration rate (eGFR) using the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI) equation

    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

Eligibility Criteria

Age18 Years - 71 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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.

  • 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
