研究设计:

单臂 

Study design:

Single arm 

研究目的:

1. 主要目的: 确定Eculizumab是否能有效预防ABO血型不相容的活体肾移植受体术后出现抗体介导的排斥反应; 2. 次要目的: 明确术前1天接受Eculizumab处理后的受体,利用红细胞溶血试验结果可预测受体接受ABO血型不相容供肾手术的安全性。  

Objectives of Study:

Primary Objective: To determine whether Eculizumab can effectively prevent antibody-mediated rejection in recipients of ABO-incompatible living donor kidney transplantation. Secondary Objective: To clarify whether the results of red blood cell hemolysis tests in recipients treated with Eculizumab one day before surgery can predict the safety of recipients undergoing ABO-incompatible kidney transplantation.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1、 年龄>=18岁,且已完善基因测序筛查,排除遗传相关性肾病,同时排除补体基因突变; 2、 患有终末期肾脏疾病,首次肾移植,已获得亲属肾移植伦理审批并计划进行ABO血型不相容的活体供体肾移植,且受体术前血型抗体滴度>=1:64; 3、 在使用eculizumab前至少6周接种过脑膜炎奈瑟菌(四价疫苗)、肺炎球菌或流感嗜血杆菌疫苗; 4、 能够理解知情同意书并愿意遵守协议

Inclusion criteria

1. Age >=18 years, and completed genetic sequencing screening to exclude hereditary kidney diseases, as well as mutations in complement genes. 2. Suffering from end-stage renal disease, undergoing first-time kidney transplantation, with ethical approval for living donor kidney transplantation and planned for ABO-incompatible living donor kidney transplantation, and with a preoperative blood type antibody titer >= 1:64 in the recipient. 3. Vaccinated against Neisseria meningitidis (quadrivalent vaccine), Streptococcus pneumoniae, or Haemophilus influenzae at least 6 weeks prior to the use of eculizumab. 4. Able to understand the informed consent form and willing to comply with the protocol.

排除标准:

1、 既往有脾切除术病史 2、 明确存在肾移植手术禁忌症,包括但不限于:存在活动性,难以控制的感染,包括细菌、真菌及病毒等感染 3、 已知或怀疑存在遗传性补体缺乏,基因测序明确有补体相关基因突变 4、 已知对治疗药物或其辅料过敏 5、 术前需要联合血浆置换或免疫吸附预处理的患者 6、 既往有脑膜炎奈瑟菌病史 7、 研究者认为可能干扰患者参与、对患者构成额外风险或与患者评估相混淆的任何健康状况(如严重心血管或肺部疾病) 8、 正参加其它临床试验的受试者,或研究人员认为其他原因不适合临床试验者

Exclusion criteria:

1. History of previous splenectomy. 2. Presence of explicit contraindications to kidney transplantation, including but not limited to: active, uncontrollable infections, including bacterial, fungal, and viral infections. 3. Known or suspected hereditary complement deficiency, with genetic sequencing confirming mutations in complement-related genes. 4. Known allergy to the investigational drug or its excipients. 5. Patients who require preoperative combination of plasma exchange or immunoadsorption as pretreatment. 6. History of meningococcal disease. 7. Any health condition that the investigator considers may interfere with the patient's participation, pose additional risks to the patient, or confound the patient's evaluation (such as severe cardiovascular or pulmonary diseases). 8. Subjects currently participating in other clinical trials, or those deemed by the investigators as unsuitable for the clinical trial for other reasons.

干预措施:

1.参与者受体在移植手术前1天接受单次剂量Eculizumab(体重>=60kg给予900 mg;体重<60kg给予600 mg),给药2小时后完善供体与受体之间红细胞溶血试验,评估受体补体抑制程度是否达到与血型抗体滴度小于1:16的同一水平;确认达到安全水平后行肾移植手术,并在受体手术后1周再次使用单次剂量Eculizumab(体重>=60kg给予900 mg;体重<60kg给予600 mg); 2、当参与者受体发生AMR时,他们可能会接受额外剂量的Eculizumab;

干预措施代码:

Intervention:

1. The recipient of the participant received a single dose of Eculizumab one day before the transplantation surgery (900 mg for weight >=60kg). For those with a body weight of less than 60kg, 600 mg should be administered. Two hours after administration, a red blood cell hemolysis test between the donor and the recipient should be completed to evaluate whether the complement inhibition degree of the recipient reaches the same level as the blood group antibody titer less than 1:16. After confirming that the safety level has been reached, kidney transplantation surgery is performed, and a single dose of Eculizumab is used again one week after the recipient's surgery (900 mg for weight >=60kg; 600 mg for weight < 60kg). 2. When the participants' receptors develop AMR, they may receive an additional dose of Eculizumab.
