Resource links provided by the National Library of Medicine

Drug Information available for: Tacrolimus

Arm Intervention/treatment
No Intervention: Immediate release tacrolimus
Patients will continue on immediate release tacrolimus
Active Comparator: Extended release tacrolimus Drug: Envarsus Oral Product
Patients will be randomised to receive either envarsus or to continue on an immediate release tacrolimus formulation




Primary Outcome Measures :
  1. Incidence of de novo allosensitisation (donor specific antibodies) at 24 months post allograft failure. [ Time Frame: 24 months ]
    Number of patients who develop new DSA in each group


Secondary Outcome Measures :
  1. Medication adherence measurement [ Time Frame: 24 months ]
    Will be measured by BAASIS questionnaire (comparison of scores)

  2. Health-Related Quality of Life measurement [ Time Frame: 24 months ]

    Will be measured by the EQ-5D-5L Questionnaire (comparison of scores) - 5D

    - 5L Questionnaire


  3. Coefficient of variation of tacrolimus levels at 24 months post allograft failure. [ Time Frame: 24 months ]
    Incorporating all study visit trough tacrolimus levels (standard deviation/mean)

  4. Adverse events [ Time Frame: 24 months ]
    Incidence of infective episodes, malignancy, diabetes, erythropoietin resistance, graft nephrectomy

  5. Chances of re-transplantation as determined by the transplant matchability calculator available from NHSBT [ Time Frame: 24 months ]
    Will be calculated by using the NHSBT calculator

  6. Proportion of patients retransplanted during the study period [ Time Frame: 24 months ]
    Proportion of patients in each arm receiving a transplant

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Able to give informed consent.
  2. Male or female, at least 18 years of age.
  3. Has renal allograft failure and is due to start haemodialysis therapy or within 28 days following starting dialysis.
  4. Has been already activated on the transplant wait list or is undergoing work up to be reactivated on the transplant list.
  5. Has no indication for graft nephrectomy at the time of transplant failure.
  6. Is receiving an immediate release tacrolimus maintenance immunotherapy regimen at the time of allograft failure.

Exclusion Criteria:

  1. Has another functioning organ transplanted (eg. pancreas, liver, cardiac) at the time of kidney allograft failure.
  2. Allograft failure within a month of transplant.
  3. Patients who are due to receive or receiving peritoneal dialysis following graft failure.
  4. Patients with detectable DSA at the time of allograft failure
  5. Receiving an extended release preparation of tacrolimus as immunotherapy at the time of graft failure.
  6. Requires continuation of maintenance immunosuppression other than prednisolone or tacrolimus (eg. Mycophenolate mofetil or sirolimus).
  7. Patients who on IR-FK conversion would require less than 0.75mg of Envarsus.
  8. HLA type of donor is unknown.
  9. Has a history of, or active co-morbidity that in the Investigator's opinion, could affect the conduct of the study.
  10. Has any condition at the time of recruitment which would prohibit or pose a relative contraindication for the continued use of tacrolimus to a target trough level of between 3-5ng/ml
  11. Active bacterial, viral (including CMV and EBV) or parasitic infections, including tuberculosis that, in the Investigator's opinion, could affect the conduct of the study.
  12. Has active malignancy.
  13. Female patients of child bearing age, who wish to consider pregnancy.
