What this study is

This is a randomized, controlled, single center study to evaluate the efficacy of Thymoglobulin induction therapy in combination with Mycophenolate Mofetil, tacrolimus, and steroids in the prevention of CAV. Approximately half of the patients will be randomized to receive a total of 5 doses of Thymoglobulin during the study. The first dose of Thymoglobulin will be administered at 1.5 mg/kg via intravenous infusion over 6 hours immediately upon arrival to the ICU post-operation (day 1). Subsequent doses of 1.5 mg/kg will be administered on days 2, 3, 4, and 5 via IV infusion over 4 hours.

Mechanistic assays (T-reg cells, Lym subsets, B cell subsets, IL-1b, cytokines, TGFb, IL-21 to be drawn at Pre-transplant, 3, 6, 12 months post-transplant) will also be performed.

All patients will be followed and monitored according to standard of care protocols for heart transplant recipients at our center.

What's being tested

  • Thymoglobulin

    Intervention · DRUG

    Approximately half of the patients will be randomized to receive a total of 5 doses of Thymoglobulin during the study. The first dose of Thymoglobulin will be administered at 1.5 mg/kg via intravenous infusion over 8 hours immediately upon arrival to the ICU post-operation (day 1). Subsequent doses of 1.5 mg/kg will be administered on days 2, 3, 4, and 5 via IV infusion over 4-8 hours.

  • Mycophenolate Mofetil

    Intervention · DRUG

    3.0 grams divided bid begun post-transplant, either IV or po as tolerated by patient. Initial dose must be given within 24 hours post-transplant. Dosing will be titrated based on recipient's body size and any adverse side effects

  • Tacrolimus

    Intervention · DRUG

    Doses of 1-4 mg bid either IV or po will be prescribed to achieve a target trough level of 10-15 ng/mL before post-operative day number 5. Target trough levels are 10-15 ng/mL for post-operative days #1-30, 8-12ng/mL days#31-60 and 5-10 ng/mL thereafter.

  • Sirolimus

    Intervention · DRUG

    Maintenance doses of sirolimus at 12 months post-transplantation

  • Corticosteroids

    Intervention · DRUG

    125 mg IV methylprednisolone immediately post-operatively x 3 doses q12hrs, then switching to oral prednisone at 1.0 mg/kg/day po divided into bid doses that are rounded off to the next higher 5 mg increment. For example, a 76 kg person would should be dosed at 38 mg po bid, which rounded off to the next 5 mg increment would be 40 mg po bid. (Equivalent dosing via an alternative route may be used if pos not tolerated or contraindicated). Prednisone will be tapered by 10 mg qd until the dose of 10 mg po bid is reached.
