Summary

Maraviroc (MVC) is a type of HIV medicine called a CCR5 inhibitor. This study will evaluate the safety and tolerability of MVC in HIV-infected adults receiving a kidney transplant.

Detailed description

MVC is a CCR5 inhibitor that may have a positive role in modulating the immune response following transplantation. The purpose of this study is to evaluate the safety and tolerability of MVC in HIV-infected adults in need of a kidney transplant. The study will also evaluate whether using both immunosuppressant drugs and MVC will improve kidney function after a kidney transplant. This study will enroll HIV-infected adults on combination antiretroviral therapy (cART) who need a kidney transplant. At the time of their kidney transplant, study participants will be randomly assigned to receive either MVC or placebo as an addition to their cART regimen. (MVC or placebo will be provided by the study. However, the HIV medicines in their cART regimens will not be provided by the study.) Participants will receive MVC or placebo throughout their participation in the study, which will be 1 to 3 years depending on when they enroll in the study. Study visits will occur at enrollment (Day 0) and post-transplant Weeks 1, 2, 4, 8, 13, 26, 39, 52, 78, 104, 130, and 156. Study visits may include a physical examination, blood collection, lymph node collection, urine sample collection, and a kidney biopsy. During the study, participants will also be monitored closely for evidence of drug toxicities, HIV treatment failure and rejection.

Interventions

Type	Name	Description
DRUG	Maraviroc	Initial dose of 300 mg twice daily (150mg twice daily if co-prescribed with a potent CYP3A inhibitor or 600mg twice daily if co-prescribed with a potent CYP3A inducer). Will be modified if GFR \< 30, if co-prescribed with a potent CYP3A inhibitor or inducer, or if the calcineurin inhibitor used for maintenance immunosuppression is changed to cyclosporine (which is only allowed for tacrolimus toxicity). Once GFR is greater than or equal to 30, the dose should be returned to the non-renal dosage. If GFR is consistently fluctuating (especially immediately post-transplant), the site investigator may choose when to resume normal dosing of study product based on clinical assessment of stability.
DRUG	Placebo	Initial dose of 300 mg twice daily (150mg twice daily if co-prescribed with a potent CYP3A inhibitor or 600mg twice daily if co-prescribed with a potent CYP3A inducer).
