SAL-0951 Tablets in the Treatment of Renal Anemia in Non-dialysis Chronic Kidney Disease

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase III Clinical Study of SAL-0951 Tablets in the Treatment of Renal Anemia in Non-dialysis Chronic Kidney Disease

This study is a phase 3 randomized, double-blind, placebo-controlled clinical study to evaluate the efficacy and safety of SAL-0951 in CKD-anemia patients in Non-dialysis, comprising 8 weeks of double-blind treatment period followed by an open-label treatment period, making up a total of 27 weeks.
