Triple therapy improves glycemic control in type 2 diabetes

Last updated July 18, 2026

Key finding

Adjusted mean reduction in HbA1c from baseline to Week 16 was significantly greater in triple FDC of DAPA+SITA+MET IR (−2.08%) versus dual FDC of SITA+MET IR (−1.38%) P < 0.0001.

This study evaluated the effectiveness of a triple fixed-dose combination of Dapagliflozin, Sitagliptin, and Metformin compared to a dual combination of Sitagliptin and Metformin in managing Type 2 Diabetes.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

This study evaluated the effectiveness of a triple fixed-dose combination of Dapagliflozin, Sitagliptin, and Metformin compared to a dual combination of Sitagliptin and Metformin in managing Type 2 Diabetes.

Clinical relevance

These findings are clinically significant as they suggest that the triple fixed-dose combination may provide a more effective treatment option for patients with Type 2 Diabetes, potentially leading to better long-term health outcomes. Improved glycemic control can reduce the risk of diabetes-related complications, making this combination an important consideration for clinicians in managing diabetes.

Keep in mind

The study's sample size and demographic characteristics may limit generalizability. Only short-term outcomes were assessed at Week 16, limiting long-term efficacy conclusions. The trial did not explore potential side effects or adverse events associated with the triple combination.

Main Effects

Triple FDC showed a significantly greater reduction in HbA1c (−2.08%) compared to dual FDC (−1.38%), P < 0.0001.

48.9% of patients on triple FDC achieved HbA1c < 7% versus 31.1% on dual FDC, P = 0.0029.

Change in fasting blood glucose was significantly greater in the triple FDC group (−36.9 mg/dL) compared to dual FDC (−30.6 mg/dL), P < 0.0001.
