Brief Summary:
This is a clinical trial comparing the immunosuppressive treatment determined according to two biomarkers, donor-specific IFN-γ ELISPOT and Mismatch of HLA between donor and recipient, in patients undergoing low immunological risk live donor kidney transplantation

Condition or disease Intervention/treatment Phase
Kidney Transplant Failure and Rejection Diagnostic Test: biomarkers driven immunosuppressive therapy Phase 4

Detailed Description:

This is a national multicenter clinical trial, controlled, randomized, stratified, parallel groups, and without masking.

This is a prospective intervention study in which two strategies for determining immunosuppressive treatment in kidney transplant patients from a live donor with low immunological risk are compared according to solid phase antibody detection techniques (cPRA 0% and isolated negative antigen) and crossmatch by negative cytotoxicity. Patients are randomized in a 1: 1 ratio to receive one of two immunosuppressive treatment strategies.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 164 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Multicenter open clinical trial, randomized, stratified by age, parallel groups
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Multicenter, Randomized Study to Evaluate the Effectiveness of the Individualization of the Immunological Risk Based on Biomarkers (Disparity of HLA and IFN-γ ELISPOT) to Optimize Immunosuppressor Treatment in Living-donor Renal Recipients
Actual Study Start Date : November 10, 2017
Estimated Primary Completion Date : November 2020
Estimated Study Completion Date : November 2020

Arm Intervention/treatment
Experimental: experimental
Biomarkers driven immunosuppressive therapy: the immunosuppressive treatment of the patients is determined according to the result of 2 biomarkers of immunological risk
Diagnostic Test: biomarkers driven immunosuppressive therapy
the immunosuppressive treatment of the patients is determined according to the result of 2 biomarkers of immunological risk

No Intervention: control
All patients receive the usual triple immunosuppressive treatment, without depending on the results of any biomarker.

  8. Treatment maintenance [ Time Frame: 24 months ]
    Proportion of patients who maintain the treatment according to the protocol at the end of the trial.

  9. Immune Response Changes [ Time Frame: 24 months ]

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

Inclusion Criteria:

  1. Adult men and women (≥18 years).
  2. Receptors of a first kidney transplant from an incompatible HLA living donor (at least 1 mismatch HLA at any antigenic level).
  3. AB0 compatible transplant.
  4. Patients with a calculated PRA of 0% by solid phase technique and absence of anti-HLA class I and class II antibodies by single antigen test (Luminex®).
  5. Patients who agree to participate in the Trial by signing the Specific Informed Consent of this study.
  6. Potentially fertile women should use high reliability contraceptive methods (Pearl-Index <1) in order to avoid pregnancy during the entire duration of the study and up to 6 weeks after the end of their treatment with Mycophenolate Mofetil (MMF). Potentially Fertile Women include any woman who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or who is not post-menopausal (defined as amenorrhea ≥ 12 consecutive months, or women who are receiving hormone replacement therapy with a documented level of follicle stimulating hormone (FSH)> 35 mlU / ml). Potentially fertile women must have a pregnancy test with a negative result in the 72 hours prior to the start of the trial.
  7. Sexually active males (including vasectomized males) who are being treated with MMF must accept the use of barrier contraceptive methods during MMF treatment and for 90 days thereafter. Potentially fertile partners of these patients should use a reliable contraceptive method during the same period, in order to minimize the risk of pregnancy.
  8. Patients must agree not to donate blood during treatment with MMF and during the 6 subsequent weeks. Males should not make a sperm donation during MMF treatment and up to 90 days after completion.

Exclusion Criteria:

  1. Patients with a calculated PRA higher than 0% per solid phase and / or anti-HLA class I and / or class II antibodies detectable by single antigen test (Luminex®).
  2. Positive result of Cross Match.
  3. Patients who receive a graft from a cadaver donor.
  4. Identical HLA patients
  5. Patients who have undergone a previous solid organ transplant (including kidney transplant) or who are going to receive another solid organ transplant concomitantly.

    • Glomerular primary focal and segmental sclerosis
    • Atypical hemolytic uremic syndrome (aHUS) / thrombotic thrombocytopenic purpura syndrome.
