Details and patient eligibility

About

This is a multi-center, randomized, parallel study to evaluate effect of exenatide on 24h-UAER in patients with diabetic nephropathy. Screening will be made to select eligible participants before intervention. The trial will include 2-week run-in period of stable doses of glargine plus lispro insulin and 24-week treatment period. After the run-in period, patients were randomly assigned to one of two groups for antihyperglycaemic therapies for a total of 24-weeks: glargine plus exenatide and continued glargine plus lispro insulin. The treatment of exenatide will be initiated by 5ug bid, and uptitrated to 10 ug bid after 4 weeks and then maintained at 10ug bid until the completion of the study. Lispro insulin will be initially treated according to the insulin dosage of previous antihyperglycaemic therapies, and further titrated up at 4-week intervals until to reach the target fasting blood glucose (FPG).

Full description

Objective: To evaluate effect of exenatide on 24-UAER in patients with diabetic nephropathy Hypothesis: Compared with glargine plus lispro group, at 24 weeks, glargine plus exenatide group can: 1) take more significant reduction of 24h-UAER; 2) take more reduction of ACR; 3) take more weight loss, blood pressure reduction; 4) take lower hypoglycemia incidence and less insulin dosage. Primary endpoint: The proportion of reduction of 24h-UAER(urinary albumin excretion rates) Secondary endpoints: 24h-UAER at 24 weeks; the rate of urinary albumin to creatinine ratio(ACR) change at 24 weeks; HbA1c, FPG,PPG, weight , BP Treatment duration: 24weeks Patient/Sites: 90 patients / 3 sites Timeline (best case): Planed duration of recruitment period: 6 month Planed date for first screening: 1 October 2015 Planed completion of the last subject: 1 March 2017 Planned completion of clinical trial report: 30 October 2017
