Renal Failure, End Stage Clinical Trial
— ONEatDCOfficial title:
A Phase I/II Monocentric Trial of Cellular Immunotherapy Based on Autologous Tolerogenic Dendritic Cells (ATDCs) Administration in Patients With Renal Insufficiency Receiving as First Transplantation a Kidney Transplant From a Living-donor.

Study type | Interventional |
To collect evidence of the safety of administering autologous tolerogenic dendritic cells (ATDC) preparations to living-donor renal transplant recipients in the context of an international European Union funded consortium aimed at evaluationg cellular immunotherapy in solid organ transplantation (The ONE Study). It is anticipated that immune regulation induced by ATDC therapy can evntually be used to reduce the need for conventional immunosuppression in transplant recipients.

Eligibility |
RECIPIENT Inclusion Criteria: 1. Chronic renal insufficiency necessitating kidney transplantation and approved to receive a primary kidney allograft from a living donor 2. Aged at least 18 years 3. Able to commence the immunosuppressive regimen at the protocol-specified time point 4. Willing and able to participate in The ONE Study IM and HEC subprojects 5. Eligible for leucapheresis prior to organ transplantation 6. Signed and dated written informed consent Exclusion Criteria: 1. Patient has previously received any tissue or organ transplant other than the planned kidney graft 2. Known contraindication to the protocol-specified treatments / medications (like known allergies to heparin) 3. Genetically identical to the prospective organ donor at the HLA loci (A.B.DR 0 mismatch) 4. PRA grade > 0 within 6 months prior to enrolment 5. Previous treatment with any desensitisation procedure (with or without IVIg) 6. Concomitant malignancy or history of malignancy within 5 years prior to planned study entry (excluding successfully-treated non-metastatic basal/squamous cell carcinoma of the skin) 7. ABO incompatibility 8. Presence of DSA (donor specific antibodies) detected by luminex prior transplantation 9. Evidence of significant local or systemic infection 10. HIV-positive, EBV-negative or suffering chronic viral hepatitis, syphilis serology- positive 11. Significant liver disease, defined as persistently elevated AST and/or ALT levels > 2 x ULN (Upper Limit of Normal range) 12. Malignant or pre-malignant haematological conditions 13. Any uncontrolled medical condition or concurrent disease that could interfere with the study objectives 14. Any condition which, in the judgement of the Investigator, would place the subject at undue risk 15. Ongoing treatment with systemic immunosuppressive drugs at inclusion (despite corticoids lower than 10 mg) 16. Participation in another clinical trial during the study or within 28 days prior to planned study entry 17. Exposure to an investigational product during the study or within 28 days prior to planned study entry 18. Female patients of child-bearing potential with a positive pregnancy test at enrolment and F01 19. Female patients who are breast-feeding 20. All female patients of child-bearing potential* UNLESS: 1. The patient is willing to maintain a highly effective method of birth control** for the duration of the study 2. The career, lifestyle, or sexual orientation of the patient ensures that there is no risk of pregnancy for the duration of the study (at the discretion of the Investigator) 21. Psychological, familial, sociological or geographical factors potentially hampering compliance with the study protocol and follow-up visit schedule 22. Any form of substance abuse, psychiatric disorder, or other condition that, in the opinion of the Investigator, may invalidate communication with the Investigator and/or designated study personnel 23. Patients unable to freely give their informed consent (e.g. individuals under legal guardianship). Criteria specific to the infusion of the ATDC_Nantes: 24. Any pro-coagulant disposition, as evidenced by a past history of thromboembolic disease or abnormal laboratory coagulation parameters which, in the judgement of the Investigator, would place the subject at undue risk 25. Any condition resulting in a substantial reduction in the volume of the pulmonary vasculature or an increase in the pulmonary vascular resistance. Any disease or disease process leading to substantially elevated pulmonary arterial pressure (as evidenced by electrocardiography, echocardiography, radiology or cardiac catheterisation) or right heart hypertrophy or dysfunction 26. Known atrial or ventricular septal defects posing a risk of paradoxical embolism of infused cells or cell aggregates 27. Known hypersensitivity to any component of the cell product or components used in the manufacture of the cell product. DONOR Inclusion Criteria: 1. Eligible for live kidney donation 2. Willing and able to provide a blood sample for The ONE Study IM Subproject 3. Willing to provide personal and medical/biological data for the trial analysis 4. Signed and dated written informed consent Exclusion Criteria: 1. Genetically identical to the prospective organ recipient at the HLA loci (A.B.DR 0 mismatch) 2. Exposure to any investigational agents at the time of kidney donation, or within 28 days prior to kidney donation 3. Any form of substance abuse, psychiatric disorder, or other condition that, in the opinion of the Investigator, may invalidate communication with the Investigator and/or designated study personnel 4. Subjects unable to freely give their informed consent (e.g. individuals under legal guardianship). 5. ABO incompatibility |
