Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Efficacy
To compare uncensored graft survival in low-risk kidney transplant recipients on tacrolimus monotherapy versus dual regimen with tacrolimus and mycophenolate mofetil.
Secondary objectives 6
- 1. To compare long-term outcomes in low-risk kidney transplant recipients on tacrolimus monotherapy versus dual regimen with tacrolimus and mycophenolate mofetil. a. Renal function and proteinuria. b. Patient survival. c. Rejection episodes. d. Infectious complications. e. Malignancy i. Skin ii. Non-skin.
- 2. To investigate the incidence and course of donor-specific antibodies in low-risk kidney transplant recipients beyond one year after transplantation (TAC vs TAC/MMF comparison).
- 3. To investigate protective antibody responses after pneumococcal vaccination in patients using tacrolimus versus tacrolimus/ mycophenolate mofetil (TAC vs TAC/MMF comparison). The persistence of this vaccination response 3 and 5 years after vaccination. The boosting effect of a repeated pneumococcal vaccination response five years after initial vaccination. The persistence of this boosted response one year after re-vaccination.
- 4. The persistence of this vaccination response 3 and 5 years after vaccination.
- 5. The boosting effect of a repeated pneumococcal vaccination response five years after initial vaccination.
- 6. The persistence of this boosted response one year after re-vaccination.

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- a. Renal function and proteinuria. (creatinin and CKD-EPI; urine spot protein/ creatinine) b. Patient survival. c. Rejection episodes. d. Infectious complications: opportunistic infections, use of antibiotics. e. Malignancy o Skin (diagnosed via routine dermatology check-up) o Non-skin.
Secondary endpoints 2
- Determination of donor-specific antibodies using Luminex single-antigen beads 4, 6 and 10 years after transplantation.
- Quantification of pneumococcal vaccination response 3 and 5 years after pneumococcal vaccination (year 4 and 6 after kidney transplantation) with the 23-serotype polyvalent pneumococcal vaccine; and 3 weeks and one year after booster vaccination 5 years after the initial vaccination.
