This is a study to compare less intense immunosuppression with a more traditional approach. The hypothesis is that less immunosuppression will provide similar protection against rejection than typical 2-3 drug therapy.

Arms Assigned Interventions
Active Comparator: MONOTHERAPY
Tacrolimus alone
Drug: Tacrolimus

Other Name: Prograf
Drug: mycophenolate mofetil therapy
Other Name: CellCept

Detailed Description:

This is a prospective, randomized, controlled (open-label) trial of 2 different strategies of immunosuppression in de novo post-heart transplant patients. The hypothesis is that immunosuppression with tacrolimus and mycophenolate mofetil, coupled with rapid steroid weaning will provide similar anti-rejection efficacy as tacrolimus with only a 2 week course of mycophenolate mofetil but including the same rapid steroid wean.

The primary endpoint is the mean International Society for Heart and Lung Transplantation (ISHLT) biopsy score over the first 6 months post-transplant. Secondary endpoints include the incidence of adverse events over the first year post-transplant, as well as all-cause mortality, 12 month ISHLT biopsy score (mean), along with the incidence of proven cytomegalovirus disease. In addition, the incidence of allograft vasculopathy as assessed by angiography or intravascular ultrasound will be compared between groups.
