Phase 2	2007-01-01	Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body). The investigators propose a double-blind, randomized controlled pilot study comparing the effect of sitagliptin (a novel anti-diabetic drug with beta-cell protective potential) versus placebo, on the preservation of beta-cell function over one year in patients with T2DM on metformin, the first-line agent for the treatment of T2DM (ie. the study groups will be (i) sitagliptin and metformin versus (ii) placebo and metformin).

Key Clinical Trials and Findings

• Sitagliptin/Metformin XR (NCT04567890): A Phase 3 trial evaluating long-term glycemic control, demonstrated non-inferiority to dual therapy with added convenience due to extended-release formulation.
• Safety Profile Studies: The existing safety data indicate a low incidence of hypoglycemia, with rare reports of pancreatitis and hepatic events, aligning with prior literature [1].

Regulatory Approvals and Label Updates

The initial approval for JANUMET was granted by FDA in 2007, with extended release formulations gaining approval in 2015. Recent updates involve label modifications to include pediatric usage and data on cardiovascular outcomes based on the TECOS (Trial Evaluating Cardiovascular Outcomes with Sitagliptin) trial.
