Kidney Transplantation in Two Highly Sensitized Candidates after CAR T-Cell Therapy

Le résumé fourni par la source

HLA sensitization poses a major challenge to kidney transplantation for patients with end-stage kidney disease, especially for highly sensitized candidates. Attempts at antibody elimination (desensitization) have had inconsistent efficacy and have often failed to produce sustained reductions in anti-HLA antibodies in patients with the highest level of sensitization (calculated panel-reactive antibody score, ≥99.9%). We now report the results for the safety run-in cohort of a multicenter phase 1 clinical study evaluating the safety and efficacy of combined CD19-targeted and B-cell maturation antigen (BCMA)-targeted chimeric antigen receptor (CAR) T cells in eliminating the cellular sources of preformed anti-HLA antibodies (ClinicalTrials.gov number, NCT06056102). Kidney transplantation was performed in two highly sensitized candidates after desensitization with the use of dual CAR T-cell therapy.
