Graft rejection: what the trials found

Management of graft rejection involves several pharmacological interventions. Tacrolimus has been evaluated for maintenance immunosuppression, showing a patient survival rate with a functioning graft of approximately 92% to 96% (p=0.26) and a rejection-free survival rate ranging from 80.1% to 86.4% (p=0.48) 2. In studies comparing cyclosporine and tacrolimus, significant differences were observed in serum creatinine levels at various intervals post-randomization (p=0.009), though the number of participants experiencing acute rejection did not reach statistical significance (p=0.206) 5.

Everolimus has been utilized as an intervention with established outcomes regarding graft stability. In one study, 33.6% to 35.1% of participants experienced composite efficacy failure at 12 months, while the rate of graft loss, death, or loss to follow-up was approximately 8.9% to 11.9% 6. A non-inferiority analysis for everolimus showed a significant result (p=0.014) regarding composite efficacy endpoints and a significant finding (p=0.001) for the incidence of graft loss, death, or loss to follow-up at 12 months 7.

Additional interventions include Alemtuzumab 1 and Azithromycin. The use of Azithromycin was associated with statistically significant lower rates of both acute rejection (p<0.05) and infection (p<0.05) compared to the control group 4.

Recent results — preliminary, needs further review

  • Infusion of Donor Hematopoietic Stem Cells and Campath-1H: 6 patients were able to withdraw immunosuppression more than 24 months post-transplant.

For the clinician treating this condition

  • Tacrolimus is established for maintenance; however, it did not show a statistically significant difference in the percentage of patients achieving specific improvements in GFR at 12 or 24 months 3.
  • Everolimus demonstrated consistent outcomes regarding graft loss and composite efficacy failures in large-scale trials [6, 7].
  • Azithromycin showed statistically significant benefits in reducing both acute rejection incidence and infection rates 4.
