What this trial studies

This clinical trial is a single center, prospective, open-label, randomized, controlled trial that compares the safety and effectiveness of Envarsus XR® to twice-daily tacrolimus in patients with end stage renal disease who are listed for a primary solitary kidney transplant. Participants will be pre-screened and, if eligible, randomized to receive either Envarsus or tacrolimus starting on the first day after their transplant surgery. The study involves a total of 9 visits over 6 months, during which participants will complete medication diaries and undergo kidney biopsies to assess their immunologic response. The findings will be shared with regulatory agencies and the sponsoring company to inform future treatment options.

Who should consider this trial

Good fit: Ideal candidates are patients with end stage renal disease who are fluent in English and listed for a primary solitary kidney transplant.

Not a fit: Patients who have previously undergone organ transplants or have significant infections or certain viral infections will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into a more effective immunosuppressive regimen for kidney transplant patients, potentially improving transplant outcomes.

How similar studies have performed: Other studies have shown promising results with similar immunosuppressive approaches, indicating potential for success in this trial.
