Safety and efficacy of prusogliptin in type-2 diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials.

Background: This study aims to conduct a systematic review and meta-analysis of the currently present literature analyzing the effectiveness and safety profile of prusogliptin, a novel dipeptidyl peptidase-IV (DPP-4) inhibitor, as compared to placebo in type 2 diabetes mellitus (T2DM) patients.

Methods: This systemic review and meta-analysis complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search strategy based on various MeSH terms was run on: PubMed/Medline, SCOPUS, and Cochrane Central, which were then systematically searched from inception till March 2024 to select all relevant Randomized Control Trials (RCT).

Results: The analysis of the findings from three RCTs with 957 patients revealed that prusogliptin reduced Hemoglobin A1c (HbA1c)% levels in T2DM patients significantly [Mean Difference (MD): -0.62, 95% Confidence Interval (CI): -0.74 to -0.50, I² = 0%, p < 0.001] and led to more patients with a HbA1c% ≤ 7% [Odds Ratio (OR): 2.65, 95%CI: 1.94 to 3.61, I² = 0%, p < 0.00001]. However, prusogliptin led to a non-significant increase in weight when compared with placebo (MD: 0.22, 95% CI: -0.50 to 0.93, I² = 60%, p = 0.551). The safety profile of prusogliptin revealed a non-significant decrease in treatment-emergent adverse events (OR: 0.90, 95% CI: 0.59 to 1.38, I² = 43%, p = 0.64) and a non-significant increase in treatment-emergent serious adverse events (OR: 1.02, 95% CI: 0.43 to 2.44, I² = 0%, p = 0.96) and drug-related adverse events (OR: 1.07, 95%CI: 0.68 to 1.69, I² = 0%, p = 0.76).

Conclusion: Prusogliptin has a favorable efficacy in attaining glycemic control in patients with T2DM. However, its safety profile yields uncertain outcomes. More literature is required for a definitive result.
