Belatacept in Heart Transplantation

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.

Randomized Trial of SGLT2i in Heart Transplant Recipients

Heart transplant (HTx) is an established therapy for advanced heart disease that restores quality of life and improves survival. However, due to preexisting comorbidities combined with the immunosuppressive therapies required after transplantation, HTx recipients remain at high risk for kidney, cardiovascular (CV), and metabolic disease. Large randomized clinical trials have recently shown that sodium-glucose cotransporter 2 inhibitors (SGLT2i) have potent kidney protective and CV benefits in many populations of patients with chronic kidney disease (CKD), CV disease and/or diabetes. SGLT2i have not been studied prospectively in HTx recipients, which represents a barrier to their use in this population. In this multicenter randomized controlled trial in Veterans with HTx, investigators will evaluate the potential benefits of empagliflozin on kidney function, cardiometabolic risk, erythropoiesis, and functional status. A total of 200 Veterans will be randomly assigned to receive either empagliflozin 10 mg daily or a matching placebo for 12 months.

Expanding the Pool in Orthotopic Heart Transplantation

This is an open-label, pilot trial to test the safety and efficacy of transplantation of hearts from HCV seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the heart transplant waitlist. Treatment and prophylaxis will be administered, using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).

Seeking Objectivity in Allocation of Advanced Heart Failure (SOCIAL HF) Therapies Trial

The primary goal of this study is to assess real-world effectiveness and implementation of an evidence-based multi-component strategy to reduce disparities in the allocation rate of advanced heart failure therapies, heart transplants and ventricular assist devices. This study proposes to implement evidence-based strategies that reduce unequal and unethical decision-making towards patients, replace subjective evaluations with objective criteria, and improve group dynamics in a randomized cluster trial. Our rigorously designed trial will inform national guidelines for advanced heart failure therapy allocation, and data are likely to be generalizable to other organ replacement treatments and advanced chronic disease decision-making processes across populations.

MCNAIR Study: coMparative effeCtiveness of iN-person and teleheAlth cardIac Rehabilitation

Cardiac rehabilitation is a medically recommended program for patients with certain heart conditions. It includes exercise training, health education, and counseling. Unfortunately, many patients do not participate in cardiac rehabilitation. Some find it challenging to attend the in-person sessions. This study aims to compare two methods of delivering cardiac rehabilitation: in-person and through telehealth. The investigators want to know if the effects of these two programs are alike and if certain individuals benefit more from one program over the other.

AERIAL Trial: Antiplatelet Therapy in Heart Transplantation

Cardiac allograft vasculopathy is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. The research team is investigating whether early antiplatelet therapy post heart transplant can prevent the development of CAV. This study will determine the feasibility of a large multicenter randomized placebo-controlled trial to answer this question.

HeartCare Immuno-optimization in Cardiac Allografts (MOSAIC)

This is an unblinded, randomized, controlled, two-arm interventional research study enrolling patients who are undergoing heart transplantation. The aim of the study is to determine whether patients at low risk of rejection can safely reduce the doses of their post-transplant immunosuppression medications using a combination of tests that include donor-specific antibodies (DSA), histology (looking at tissue from the donor heart), donor-derived cell-free DNA (AlloSure), and gene expression profiling (AlloMap). Eligible participants will be randomized in a 1:1 ratio into the HeartCare immune-optimization (intervention) arm or the corresponding observational (control) arm. AlloSure and AlloMap are the components of the HeartCare panel developed by CareDx.

Brazilian Clinical Registry of Heart Transplantation

Prospective cohort clinical study, registry-based, multicenter, national, with the consecutive inclusion of patients with a history of Heart Transplantation in Brazil. The clinical registry will involve the participation until 25 centers. Patients will be included up to 30 days after Heart Transplant surgery and will be followed for one year. Laboratory tests and clinical parameters wil be collected in two clinical visits (6mo and 12 mo). The outcomes evaluate will be the total hospitalizations and all-cause death. It is expected to include 730 patients with a 12-month follow-up from the day of the transplant surgery. The findings of the HESTIA Registry may guide the management of post-heart transplant patients, aiming at reducing morbidity and mortality within 12 months after heart transplant surgery.
