Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to determine whether a single dose of eculizumab can effectively prevent antibody-mediated rejection in recipients undergoing living donor kidney transplantation with a different ABO blood group type than their donors

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Kidney transplantation is considered the best therapy for patients with end-stage renal disease. ABO-incompatible living donor kidney transplantation (ABOi-LDKTx) is one of the strategies to expand the pool of donors. However, the blood group antibodies in recipients can lead to acute rejection, resulting in transplant failure. Before transplantation, the use of rituximab (RTX) to remove B cells; plasmapheresis to eliminate blood group antibodies can mitigate the occurrence of acute rejection and enhance the success rate of transplantation.

The complement system plays a vital role in antibody-mediated rejection (AMR). Eculizumab can target the C5 protein of the complement system and then block the activation. Therefore, we hypothesize that the pretransplant use of eculizumab may prevent the AMR in ABOi-LDKTx.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Eculizumab

A single dose of eculizumab was given on the Day 0 before the transplant surgery.

Group Type EXPERIMENTAL

Eculizumab

Intervention Type DRUG

On the Day 0, participants received a single dose of eculizumab before the transplant surgery: 900 mg (blood type antibody titer ≥ 1:64 and/or body weight ≥ 60 kg) or 600 mg (blood type antibody titer \< 1:64 and body weight \< 60 kg). Plasmapheresis was not planned. When participants developed AMR, they may receive additional dose of eculizumab.
