Who can join
- Donors: 1. Age ≥18 years and able to consent
- Patients: 7. Negative CDC crossmatch with the donor
- Patients: 8. Negative PCR test result for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) at Screening
- Patients: 9. Patient's living donor gave written consent for trial participation
- Patients: 10. Ability to understand the nature and scope of the clinical trial
- Patients: 11. Written informed consent given prior to any trial-related procedures
- Patients: 12. Female patients of childbearing potential must: a. have a negative pregnancy test (blood) at Screening. b. either commit to true abstinence from heterosexual contact or agree to use, and be able to comply with, 2 highly effective measures of contraception control (failure rate less than 1% per year when used consistently and correctly) without interruption, during the trial participation. Patients who discontinue mycophenolic acid derivate during the trial participation can switch to 1 highly effective contraceptive method 6 weeks after the end of mycophenolic acid derivative treatment. Reliable methods for this trial are: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, sexual abstinence or vasectomized sexual partner. Abstinence from heterosexual contact is only accepted as true abstinence: when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods and withdrawal] is not an acceptable method of contraception.) Postmenopausal (no menses for at least 1 year without alternative medical cause) or surgically sterile female patients (tubal ligation, hysterectomy or bilateral oophorectomy) may be enrolled. c. agree to abstain from breast feeding during the trial participation.
- Patients: 13. Male patients must practice true abstinence or agree to use a condom during sexual contact with a pregnant woman or a woman of childbearing potential during the trial participation and for at least 90 days after the end of trial participationmycophenolic acid derivative treatment, even if he has undergone a successful vasectomy.
- Donors: 2. Ability to understand the nature and scope of the clinical trial
- Donors: 3. Written consent form given prior to any trial-related procedures (including PBMC donation)
- Patients: 1. Patient with CKD in stage 5 (e.g., estimated glomerular filtration rate [GFR] <15mL/min and/or on renal replacement therapy), who are in preparation for kidney transplantation from a live donor
- Patients: 2. Age ≥18 years, <75 years
- Patients: 3. ABO-blood group identical or compatible with donor
- Patients: 4. First kidney transplantation
- Patients: 5. Complement dependent cytotoxicity (CDC)-panel reactive antibodies <20%
- Patients: 6. No detection of a donor-specific HLA-antibody in the Luminex-Assay (cutoff: mean fluorescence intensity [MFI] ≤1,000)
