Use of Tacrolimus and MTOR Inhibitors With Anticipatory Therapy vs. Tacrolimus and Mycophenolic Acid With Universal Prophylaxis in Renal Recipients at High Risk of Posttransplant Cytomegalovirus.

Plain-language summary

The overall objective of this project is to optimise preventive treatment of CMV infection/disease in renal transplant recipients at increased risk of CMV post-transplantation. The specific objectives are: (1) To compare the incidence of CMV infection/disease at 6 months post-transplant in Ig G CMV positive (R+CMV) recipients receiving induction treatment with thymoglobulin and one of the two maintenance immunosuppressive treatment regimens used in routine clinical practice : tacrolimus and MTOR inhibitors (group 1) or tacrolimus and mycophenolic acid (group 2); (2) To monitor CMV-specific cellular immunity before transplantation, at 15, 30 and 90 days post-transplantation. For this purpose, an exploratory phase 4 clinical trial has been designed in which will select 30 R+CMV patients receiving renal transplantation with induction treatment with thymoglobulin. After signing informed consent, patients will be randomised to receive one of the two immunosuppression regimens indicated above. The patients in group 1 will receive early therapy as a CMV prevention strategy and patients in group 2 will receive universal prophylaxis for 3 months. Follow-up visits to will be conducted according to the usual protocol and clinical and virological variables will be collected. In addition, blood samples will be collected for the assessment of CMV-specific cellular immunity before and after transplantation. The primary endpoint is the presence of CMV infection/disease post-renal transplantation at 6 months. Secondary variables include renal function, acute rejection, patient and graft survival and the occurrence of surgical or haematological complications.
