Summary

While the number of kidney transplants is increasing worldwide every year, there is a clear imbalance between the high number of patients in the waiting list and those receiving a transplant and importantly, among waitlist patients there is a progressively higher number of highly sensitised patients that have very low or even no chance to receive a compatible organ. These patients remain for very long periods of time on dialysis therapy, having lower quality of life, lower life expectancy and produce higher health-related costs. Unfortunately, current desensitization therapies have shown very poor success and patients usually lose these grafts very fast if transplanted across a positive cross-match. Therefore, there is an urgent need for novel desensitization strategies capable of overcoming this immunological barrier and allow an increasing number of patients to receive a HLA-compatible kidney allograft.This is a non-randomized, single arm study, combination trial designed according to the Recommendations of the Clinical Trial Design Task Force of the NCI Investigational Drug Steering Committee. The study will enroll 12 patients with cPRA or TGI ≥99% on the deceased donor kidney transplant waiting list, who have not received a compatible donor offer for \>3 year. According to inclusion and exclusion criteria patients will be screened to participate in the trial.

Interventions

COMBINATION_PRODUCT

Each patient will undergo in the first step of the study belatacept treatment and in the second apheresis and daratumumab

Four consecutive cohorts each comprising 3 patients are planned. STEP I: Patients receive Belatacept 10mg/kg, administered on days 1, 5, end of week 2, 4 and 8 . Patients without a significant decrease in the global cPRA (cPRA or TGI ≥99%) or significant reduction of anti-HLA Ab MF will continue to the second step. STEP II: (15 weeks) One week after the last injection of belatacept, patients will undergo 4 sessions of apheresis (plasmapheresis (PF) or Immunoadsorption (IA)) which will be given every 48h. At week 11, patients will receive 4 doses of daratumumab (8mg/kg) every two weeks until week 17. Daratumumab will be alternated with 4 additional doses of belatacept 5 mg/kg FOLLOW-UP (24 weeks) All patients exiting the study, either having completed all treatment courses or exiting prematurely (transplanted or not), will be proposed monthly follow-up visits
