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). This study may demonstrate an important beta-cell protective capacity of sitagliptin.
Hypothesis: In patients with T2DM on metformin, treatment with the DPP-IV inhibitor sitagliptin will preserve pancreatic beta-cell function.
Medications currently used in the treatment of T2DM have not been shown to modify the progressive decline in beta-cell function that occurs over time. Recent evidence, however, suggests that a new class of anti-diabetic medications, called dipeptidyl peptidase-IV (DPP-IV) inhibitors, may be able to protect beta cells and hence alter the natural history of T2DM. We thus wish to study the effect of sitagliptin (a DPP-IV inhibitor) on the preservation of beta-cell function in patients with T2DM randomized to either (i) sitagliptin and metformin or (ii) placebo and metformin.

Diabetes mellitus (DM) carries an elevated risk for cardiovascular disease. Here, we assessed alirocumab efficacy and safety in people with/without DM from five placebo-controlled phase 3 studies.
Despite improved understanding of the pathophysiology of type 2 diabetes mellitus, explanations for individual variability in disease progression and response to treatment are incomplete. The gut micr...
A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.
The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).
A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
A type of diabetes mellitus that is characterized by severe INSULIN RESISTANCE and LIPODYSTROPHY. The latter may be generalized, partial, acquired, or congenital (LIPODYSTROPHY, CONGENITAL GENERALIZED).
