Summary

The investigator hypothesizes that the combined use of (1) Donor-derived cell-free DNA (dd-cfDNA) in peripheral blood predicting anti-donor immunological activation or quiescence (2) interactive and actionable data analytics delivered at the bedside will promote safe clinical follow-up of kidney transplant patients with less need for invasive biopsy and less induced risk surveillance by allograft protocol biopsies to assess allograft rejection in clinically stable kidney transplant patients.

In addition, the evaluation of the transcriptional changes in tissue samples in selected patients using automated processing of digital slide images and intragraft gene expression profiles will provide a better diagnosis of the rejection mechanisms to provide the best therapeutic approach as compared to current clinical practice.

We therefore propose a French, multicenter, prospective randomized trial comparing two strategies of follow-up: in the first group, a biopsy is performed at M3, M12 and for clinical indication whenever considered necessary by the clinician during the first 18 months of follow-up after transplant. In the second group, patients will have the same follow-up as in the first group, but reports providing dd-cfDNA results and relevant medical parameters will be provided to the physician to help him in the decision to perform a biopsy or not.

Conditions

  • Renal Transplantation

Interventions

BIOLOGICAL

dd-cfDNA-guided

In groups I and II, the blood sample for dd-cfDNA assay will be taken on D0, just prior to transplantation, for all patients. in addition, for patients following a dd-cf DNA-guided strategy based on dd-cf DNA ; samples for dd-cf DNA assay will be taken at M3 and M12 visits and at visits for clinical indication (5 maximum) and the blood will be sent to the PARCC technical platform of INSERM UMR 970. By combining the dd-cfDNA level and relevant medical data, an integration report will be sent to the centers to stratify patients into high-risk or low-risk rejection profiles. If the patient is classified in the "low risk of rejection" subgroup, he may decide not to perform the biopsy. If the patient is classified in the "high risk of rejection" subgroup, he may decide to perform the biopsy within 15 days of the sample being taken. the decision to perform the biopsy is left to the discretion of the physician.
