NCT03386539

Brief Summary

The TEAMMATE Trial will enroll 210 pediatric heart transplant patients from 25 centers at 6 months post-transplant and follow each patient for 2.5 years. Half of the participants will receive everolimus and low-dose tacrolimus and the other half will receive tacrolimus and mycophenolate mofetil. The trial will determine which treatment is better at reducing the cumulative risk of coronary artery vasculopathy, chronic kidney disease and biopsy proven-acute cellular rejection without an increase in graft loss due to all causes (e.g. infection, PTLD, antibody mediated rejection).

Outcome Measures

Primary Outcomes (2)

  • EFFICACY: MATE-3 Score

    MATE-3 is a validated score ranging from 0 to 12. The score represents the cumulative burden of three major adverse transplant events: Coronary Artery Vasculopathy (CAV), Chronic Kidney Disease (CKD), and Biopsy-proven Acute Cellular Rejection (ACR)

    30 months post-randomization

  • SAFETY: MATE-6 Score

    MATE-6 is a validated score ranging from 0 to 24. The score represents the cumulative burden of all six major adverse transplant events: Coronary Artery Vasculopathy (CAV), Chronic Kidney Disease (CKD), Biopsy-proven Acute Cellular Rejection (ACR), pathologic diagnosis of Antibody-Mediated Rejection (AMR), Infection, and Post-Transplant Lymphoproliferative Disorder (PTLD)

    30 months post-randomization

Secondary Outcomes (26)

  • Efficacy: Overall patient survival

    Up to 30 months post-randomization

  • Efficacy: Overall allograft survival

    Up to 30 months post-randomization

  • Efficacy: Change in kidney function

    0 to 6 months, 0 to 12 months, 0 to 30 months post-randomization

  • Efficacy: Freedom from CKD event

    Follow-up through 30 months post-randomization

  • Efficacy: Freedom from CAV event

    Follow-up through 30 months post-randomization

  • +21 more secondary outcomes

Study Arms (2)

Everolimus/Low-Dose Tacrolimus

EXPERIMENTAL

Everolimus approximately 0.6 mg/m2/dose taken by mouth every 12 hours for 30 months. Everolimus dose will be adjusted to achieve a trough concentration of 3-8 ng/ml. Tacrolimus 0.0125 mg/kg/dose by mouth every 12 hours for 30 months. (Tacrolimus dose will be adjusted to achieve a trough concentration of 3-5 ng/ml until subjects are 1 year post-heart transplant. After 1 year post-heart transplant the tacrolimus dose will be adjusted to achieve a trough concentration of 2.5-4.5 ng/mL.)

Drug: EverolimusDrug: Tacrolimus

Tacrolimus/Mycophenolate Mofetil

ACTIVE COMPARATOR

Tacrolimus 0.05 mg/kg/dose by mouth every 12 hours for 30 months. (Tacrolimus dose will be adjusted to achieve a trough concentration of 7-10 ng/ml until subjects are 1 year post-heart transplant. After 1 year post-heart transplant the tacrolimus dose will be adjusted to achieve a trough concentration of 5-8 ng/mL.) Mycophenolate mofetil 600 mg/m2/dose by mouth every 12 hours for 30 months.

Drug: TacrolimusDrug: Mycophenolate Mofetil

  • High-risk for rejection defined as active rejection, recurrent (≥ 2 episodes of grade 2R rejection) cellular rejection, recurrent rejection (≥ 2 episodes of any grade) with hemodynamic compromise, steroid-resistant rejection or unresolved antibody-mediated rejection during the first 6 months post-heart transplant
  • Graft dysfunction (LVEF \<40% or wedge pressure \>22 mmHg or cardiac index \<2.2 L/min/m2)
  • Stage 4 or 5 CKD (eGFR \<30 ml/min/1.73 m2)
  • Moderate or severe proteinuria
  • Active infection requiring hospitalization or treatment dose medical therapy.
  • Patients with ongoing wound healing problems, clinically significant wound infection requiring continued therapy or other severe surgical complication in the opinion of the Site Principal Investigator.
  • Uncontrolled diabetes mellitus.
  • Diagnosis of post-transplant lymphoproliferative disorder (PTLD) during the first 6 months post-heart transplant.
  • History of non-adherence to medical regimens.
  • Patients who are treated with drugs that are strong inducers or inhibitors of cytochrome P450 3A4 (CYP3A4) and cannot discontinue the treatment
  • Patients who are pregnant or breast-feeding or intend to get pregnant during the study period.
