简要总结
The purpose of this RCT is to investigate the efficacy and safety of Sugar cane polysaccharide LC-Z300-01 on proteinuria in participants with diabetic kidney disease (DKD).
详细描述
The incidence of diabetic nephropathy has shown a year-by-year increase, establishing it as the leading cause of uremia. Despite guideline-recommended therapies such as RAS inhibitors, patients with diabetic nephropathy continue to face elevated risks of disease progression, particularly when massive proteinuria persists. Early intervention through nephropathy management can effectively slow renal function deterioration, demonstrating substantial clinical value in mitigating uremia risk.
LC-Z300-01, a sugarcane-derived polysaccharide formulated as a dietary supplement, is being evaluated in this prospective, placebo-controlled, double-blind, randomized clinical trial. Sixty participants with confirmed diabetic nephropathy will be randomly allocated (1:1:1) to receive low-dose polysaccharide, high-dose polysaccharide, or placebo for 24 weeks of intervention and subsequent monitoring.
The predefined primary endpoint is the absolute change in uACR from baseline to week 24. Secondary endpoints encompass: (1) proportion of participants achieving ≥30% reduction in uACR versus baseline; (2) annualized eGFR decline rate; (3) HbA1c trajectory alterations; and (4) time-in-range (TIR) glycemic control metrics. Safety assessments will be conducted for all enrolled subjects receiving ≥1 administered dose.
