RCT Comparing Immunosuppressive Regimens in Elderly Renal Transplant Recipients

• Status: Recruiting
• Trial end date: 2026-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Open label, randomized, multicenter, intervention trial comparing standard immunosuppression with tacrolimus and mycophenolate mofetil with a low exposure tacrolimus regimen in combination with everolimus.

The primary objective is to test the hypothesis that an age-adapted immunosuppressive regimen targeted at reduced immunosuppression with low calcineurin inhibitor (tacrolimus) exposure in combination with everolimus will result in improved outcome in elderly recipients of A: Kidneys from older deceased donors (>64 years) and B: Kidneys from living donors (all ages) and younger deceased donors (<65 years).

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

2. Male or female subject ≥65 years old

3. Subject randomized within 24 hours of completion of transplant surgery

4. Stratum A: Recipient of a primary (or secondary, if first graft is not lost due to immunological reasons) renal transplant from a deceased donor aged 65 years or older

5. Stratum B: Recipient of a primary (or secondary, if first graft is not lost due to immunological reasons) renal transplant from a deceased donor aged below 65 years or a living donor of any age

Exclusion Criteria: Exclusion criteria for both stratum A and B

5. Recipients of a kidney from an HLA-identical related living donor

6. Known intolerability for one or more of the study drugs

7. Subject who is HIV positive

8. HBsAg and/or a HCV positive subject with evidence of elevated liver function tests (ALT/AST levels ≥2.5 times ULN). Viral serology results obtained within 6 months prior to randomization are acceptable

9. Recipient of a kidney from a donor who tests positive for human immunodeficiency virus, (HIV), hepatitis B surface antigen (HBsAg) or anti-hepatitis C virus (HCV)

10. Subject with severe systemic infections, current or within the two weeks prior to randomization

11. Subject with severe restrictive or obstructive pulmonary disorders
