简要总结
The purpose of this trial was to determine the safety and efficacy of eculizumab in the prevention of antibody-mediated rejection (AMR) in sensitized recipients of a living donor kidney transplant requiring desensitization therapy.
详细描述
The main objective of this study was to evaluate the safety and efficacy of eculizumab to prevent AMR in sensitized recipients of living donor kidney transplants requiring desensitization therapy prior to transplantation. The primary endpoint focused on acute AMR during the first 9 weeks post-transplantation.
Patients were to be vaccinated against N. meningitidis at least 14 days prior to study drug initiation and revaccinated 30 days later. If not vaccinated 14 days prior, prophylactic antibiotics were to be administered. Pre-transplant infectious disease assessment was to be performed as part of the screening assessment.
Patients were to undergo desensitization therapy according to the practice of the local transplant center prior to transplantation, and this desensitization practice was to be uniformly applied for all patients at that center throughout the study. The actual length of desensitization for an individual patient was based on the clinical judgment of the Transplant Center team. Rituximab was prohibited in all patients as part of the pre-transplantation desensitization therapy due to potential pharmacodynamic interactions.
The control group was designed to test eculizumab against the best available care (referred to as standard of care, or SOC) consisting of plasmapheresis (PP) and/or intravenous immunoglobulin (IVIg). The best available care consisting of PP and IVIg was chosen because these modalities combined represented the most prevalent therapy reported in the literature and were the best available therapies at the time of this protocol's inception as per the transplant community.

研究组 & 干预措施
Eculizumab
Patients were to receive eculizumab 1200 mg prior to allograft transplantation (Day 0, starting approximately one hour prior to kidney allograft reperfusion), eculizumab 900 mg (Days 1, 7, 14, 21, and 28), and eculizumab 1200 mg (Weeks 5, 7 and 9). All doses of eculizumab were administered intravenously: the median infusion time was 39 minutes.
干预措施: Eculizumab (Drug)
结局指标
主要结局
Treatment Failure Rate
时间窗: 9 weeks post-transplantation
The primary efficacy variable was a binary outcome variable where patients meeting the composite endpoint of the occurrence of 1) biopsy-proven acute AMR, 2) graft loss, 3) patient death, or 4) loss to follow-up definition at Week 9 post-transplantation were considered treatment failures and all others were considered treatment successes.
