| Main Objective: To investigate changes in subcellular markers of growth, apoptosis, differentiation, survival, inflammation and oxidative stress, in relationship with cellular acute rejection, in de novo cardiac transplant recipients receiving either tacrolimus or cyclosporine as primary immunosuppressant.;Secondary Objective: 1. to investigate changes in circulating markers of inflammation and oxidation concomitantly with the changes in the subcellular markers outlined above and with the magnitude of acute cellular rejection in the 2 treatment groups. 2. to evaluate efficacy with respect to graft survival, acute rejection (AR) episodes (frequency, severity, time to event and resolution), treatment for AR, and successful steroid taper in the treatment groups. 3. to assess safety with respect to adverse events in the treatment groups: dyslipidemia, hypertension, diabetes mellitus, nephrotoxicity, clinical chemistry and hematology findings. 4. to measure treatment failure and crossover for treatment failure in the treatment groups. 5. to measure cardiovascular risk status using the Framingham assessment. (NA for pediatric patients) 6. to measure Quality of Life and general well-being using patient health surveys. 7. to measure impact of treatment choice on healthcare resource use.;Primary end point(s): The change in the markers of growth, apoptosis, inflammation and oxidation measured in endomyocardial biopsies. ERK 1/2, JNK, and p38 MAPK have been selected as the principal primary endpoint parameters. Additional primary endpoint parameters are MEK 1/2, MEK 3/6, cSrc, ERK 5, AKT, Bax/Bcl-2, and nitrotyrosine.;Timepoint(s) of evaluation of this end point: Week 2 to 1 year post-implant | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: Week 2 to 1 year post-implant;Secondary end point(s): Systemic markers 1. Changes in circulating markers of inflammation and oxidation (adhesion molecules and other markers of inflammation MCP-1, s-ICAM, E-selectin, homocysteine, hsCRP; and markers of redox state F2 isoprostanes, T-bars, nitrotyrosine, GSH/GSSG) and circulating markers of myocardial damage (troponin t and BNP). Efficacy 2. ISHLT acute rejection profiles and time to first acute rejection episode following de novo cardiac transplant. 3. Number of patients requiring antilymphocyte antibodies or steroids for treatment of severe acute rejection. 4. Number of acute rejection episodes requiring treatment regardless of biopsy grade or presence of hemodynamic compromise. 5. Mean cases of acute rejection (MCAR) per patient. 6. Incidence of successful steroid taper or withdrawal at 26 and 52 weeks. 7. Incidence of treatment failure and crossover for treatment failure. 8. Exploratory evaluation of patients’ general well being using the following patient questionnaires: ? SF-12v2™ Health Survey (32, Appendix 9). (NA for pediatric patients) ? Heart Transplant Recipient Opinions of Immunosuppressive Medications (Appendix 10). (NA for pediatric patients) ? For pediatric patients, the following will be used: o Functional Status IIR o PedsQL™ Pediatric Quality of Life Inventory, Version 4.0 o SF-10 for Children™ o Impact on family Scale Safety 9. Effects on glucose metabolism (fasting glucose, HbA1c, 2-hour oral glucose tolerance test) and incidence of post-transplant diabetes mellitus. 10.Incidence of dyslipidemia defined as lipid profiles not satisfying the Canadian recommendations for high-risk patients 11.Incidence of post-transplant hypertension (JNC-VI). 12.Impairment in renal function as defined by magnitude of change in estimates of glomerular filtration rate, protein excretion rate, and serum cystatin C levels. 13.Framingham assessment for c | — |
