Summary

Renal transplantation is the best choice for the treatment of end-stage renal disease, but the long-term survival of the graft is still remains a challenge. Chronic antibody-mediated rejection (AMR) is the main factor affecting the long-term survival of the graft. There is still no effective treatment for chronic antibody-mediated rejection, even in the active phase (CaAMR). In recent years, new therapeutic drugs based on the generation of DSA and the mechanism of AMR, including protease inhibitor bortezomi, CD20 monoclonal antibody, C5 monoclonal antibody and IL-6 antibody, have not been able to effectively eliminate and inhibit the generation of DSA, nor have they been proved to have a definite effect on AMR.

CD38 is a type II transmembrane protein that is highly expressed on plasma cells and NK cells, which are considered to play a key role in the occurrence and development of AMR. Recently, a few cases have reported that CD38 monoclonal antibody combined plasma exchange and/or IVIG may be an effective strategy for the prevention and treatment of AMR, but the effectiveness and safety of daratumumab monotherapy on CaAMR were unknown. This is a multicenter, prospective, single arm clinical study. The study will enroll 15 renal transplant recipients with positive DSA and CaAMR confirmed by biopsy after renal transplantation. According to inclusion and exclusion criteria patients will be screened to participate in the trial.

Conditions

  • Antibody-mediated Rejection
  • Kidney Tranplant

Interventions

DRUG

Daratumumab

After successful enrollment, the patient will receive daratumumab of 16mg/kg once every two weeks (0-22 weeks) for a total of 12 times. Peripheral blood samples were collected from 0 to 24 weeks (weeks 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24) for routine blood tests, liver and kidney function electrolytes, tacrolimus or cyclosporine trough concentrations, HLA antibody quantification (weeks 0, 4, 8, 12, 16, 20, and 24), infection indicators (weeks 0, 8, and 24), immune status assessments (weeks 0, 4, 8, 12, 16, 20, and 24), and biopsy of transplanted kidneys was performed at 24 weeks to assess pathological changes.
