A Multicenter, Randomized, Double-blind, Positive-control, Non-inferiority Clinical Trial on the Effectiveness and Safety of HCA-N Solution for the Preservation of Kidney Grafts During Kidney Transplantation

13. September 2026 aktualisiert von: Zhongnan Hospital
To verify the effectiveness and safety of the HCA-N solution in actual clinical preservation, this study intends to conduct a prospective, randomized, and positive control clinical trial. Using the classic HTK solution as a reference, the study will focus on evaluating the performance of the HCA-N solution in terms of the incidence of delayed recovery of transplant kidney function and the speed of early renal function recovery, with the aim of providing better preservation solution selection and high-level evidence-based guidance for clinical practice in kidney transplantation.

Sample Size:250 subjects in total, with 125 subjects in each of the test and control groups.

Study Centers:Approximately 20 centers Primary Endpoint:(1)Percentage of subjects experiencing delayed graft function (DGF) post-transplantation. (2)DGF is defined as the need for dialysis within 1 week after transplantation.

Study Procedures

Screening Period (V1, D-14 to D-1):

Screen potential kidney transplant donors and recipients for eligibility. Obtain signed informed consent. Collect recipient demographic information, medical history, treatment history, and current disease history. Collect blood type (ABO and Rh), immunological test results (PRA, donor/recipient crossmatch test, HLA typing). Complete screening assessments: vital signs, physical examination, complete blood count, urinalysis (if applicable, same below), blood biochemistry, coagulation function, transfusion-transmitted infection markers, pregnancy test (for women of childbearing potential only), 12-lead ECG, and chest CT or X-ray. (Except for vital signs and physical examination, results from tests performed within 7 days prior to screening are acceptable.) Record the subject's preoperative eGFR baseline value (last value before transplantation).

Surgery Day (V2, D0) Enrollment/randomization assignment; Record vital signs; Renal transplantation surgery; Kidney preservation; Observe device deficiencies; Record post-transplant dialysis events; Record adverse events and concomitant treatments. Follow-up Visit (V3, D1) Record vital signs; Laboratory tests: complete blood count, blood biochemistry, and urinalysis; Record eGFR on Day 1 post-transplantation; Record dialysis events post-transplantation; Record adverse events and concomitant treatments. Follow-up Visit (V4, D3) Record vital signs; Laboratory tests: complete blood count, blood biochemistry, and urinalysis; Record eGFR on Day 3 post-transplantation; Record dialysis events post-transplantation; Record adverse events and concomitant treatments. Follow-up Visit (V5, D7 ± 1) Record vital signs; Laboratory tests: complete blood count, blood biochemistry, and urinalysis; Record eGFR on Day 7 post-transplantation; Record dialysis events post-transplantation; Record adverse events and concomitant treatments. Follow-up Visit (V6, D14 ± 2) Record vital signs;

Laboratory tests: complete blood count, blood biochemistry, and urinalysis; Record eGFR on Day 14 post-transplantation; Record dialysis events post-transplantation; Record adverse events and concomitant treatments. Follow-up Visit (V7, D28 ± 3) Record vital signs and physical examination; Laboratory tests: complete blood count, blood biochemistry, and urinalysis; Coagulation function, pregnancy test (for women of childbearing potential only); 12-lead ECG; Chest CT or X-ray; Record eGFR on Day 28 post-transplantation; Record dialysis events post-transplantation; Record adverse events and concomitant treatments. Long-term Follow-up Record eGFR; Record graft survival status and patient survival information; Record device-related adverse events. Statistical Analysis Primary Endpoint: The primary endpoint is the percentage of subjects experiencing delayed graft function (DGF) post-transplantation. Chi-square test / corrected chi-square test / Fisher's exact test will be used for comparison between groups, and 95% confidence intervals will be calculated.

Secondary Endpoints:

Percentage of subjects with eGFR > 30 mL/(min·1.73 m²) within 28 days post-transplantation: Chi-square test / corrected chi-square test / Fisher's exact test will be used for comparison between test and control groups, and 95% confidence intervals will be calculated; Time to first eGFR > 30 mL/(min·1.73 m²) within 28 days post-transplantation: Kaplan-Meier method will be used to estimate median time, 25%/75% percentiles, and their 95% confidence intervals; Kaplan-Meier curves will be plotted; Changes in eGFR from baseline at Days 1, 3, 7, 14, and 28 post-transplantation: Descriptive analysis (sample size, mean, standard deviation) will be performed for each group; between-group comparisons will be made using t-test / rank-sum test.

Safety Analysis: To be performed based on the Safety Set (SS). The number of cases, number of subjects, and incidence rates of adverse events and serious adverse events will be calculated. Adverse events will be summarized by severity, SOC/PT, relationship to the study product, etc., in terms of number of events, number of subjects, and incidence rates. Detailed listings of adverse events will be provided. Physical examination, vital signs, 12-lead ECG, laboratory, and other test results will be summarized descriptively.
