|Condition or disease||Intervention/treatment||Phase|
|Immunosuppression||Drug: Tacrolimus Drug: combination therapy||Phase 4|
This was a prospective, randomized, controlled (open-label) trial of 2 different strategies of immunosuppression in de novo post-heart transplant patients. The hypothesis was that immunosuppression with tacrolimus and mycophenolate mofetil, coupled with rapid steroid weaning would 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 was the mean International Society for Heart and Lung Transplantation (ISHLT) biopsy score over the first 6 months post-transplant. Secondary endpoints included 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 was compared between groups.

- Mean International Society for Heart and Lung Transplantation Biopsy Score Over the First 6 Months Post-transplantation [ Time Frame: 6 months ]Mean ISHLT biopsy score Biopsies of the heart may be various grades and each is assigned a numerical score. Grade 0 is 0 points, 1A = 1, 1B = 2, grade 2 = 3, grade 3A = 4, Grade 3B = 5, and grade 4 = 6 units. The mean biopsy score is the numeric average of the biopsy scores for the first 6 post-transplant months. Best value is 0, worst score is 6.
- Percent of Patients Alive at One Year Post-transplant [ Time Frame: 1 year ]Percent of patients alive at one year post-transplant. In other words, all cause mortality over time
- Number of Patients With Cytomegalovirus (CMV) at One Year Post-transplant [ Time Frame: 1 year ]Number of patients developing cytomegalovirus disease by 1 year post-transplant
- Number of Patients With Allograft Vasculopathy (CAD) at One Year Post Transplant [ Time Frame: 1 year ]Number of patients diagnosed with allograft vasculopathy / coronary artery disease (CAD) at one year post transplant
- Mean ISHLT Biopsy Score Over First Year Post-transplant [ Time Frame: 1 year ]Mean ISHLT biopsy score Biopsies of the heart may be various grades and each is assigned a numerical score. Grade 0 is 0 points, 1A = 1, 1B = 2, grade 2 = 3, grade 3A = 4, Grade 3B = 5, and grade 4 = 6 units. The mean biopsy score is the numeric average of the biopsy scores for the first 6 post-transplant months. Best value is 0, worst score is 6.
