Dorzagliatin for Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of Randomized Phase II/III Trials.

PURPOSE

Dorzagliatin is a glucokinase agonist with effects on type 2 diabetes mellitus (T2DM). This study included a meta-analysis on the efficacy and safety of dorzagliatin in the treatment of T2DM.

METHODS

The Cochrane Central Registry of Controlled Trials, PubMed, and Embase were searched from inception to July 25, 2022. A total of 3 studies including 1333 patients were identified in this meta-analysis.

FINDINGS

Overall, the meta-analysis showed that dorzagliatin remarkably reduced glycated hemoglobin levels versus placebo by 0.66%. The results of the meta-analysis showed a significant reduction in fasting plasma glucose of 6.77 mg/dL between dorzagliatin and placebo. In addition, dorzagliatin reduced 2-hour postprandial glucose (2h-PPG) by 43.87 mg/dL compared with placebo. Furthermore, the meta-analysis of available data revealed a significant reduction in the Homeostasis Model Assessment of Insulin Resistance of 0.07 between dorzagliatin and placebo. The risk of adverse events was slightly higher with dorzagliatin than with placebo.

IMPLICATIONS

Dorzagliatin significantly reduced glycated hemoglobin levels, fasting plasma glucose levels, 2h-PPG, and homeostasis model assessment 2 of insulin resistance in patients with T2DM. It was well tolerated and had good liver and kidney safety profiles.
