Anagliptin and sitagliptin as add-ons to metformin for patients with type 2 diabetes: a 24-week, multicentre, randomized, double-blind, active-controlled, phase III clinical trial with a 28-week extension. [2015]
We conducted a 24-week, multicentre, double-blind, randomized study with a 28-week extension to compare the efficacy and safety of anagliptin and sitagliptin as an add-on to metformin in patients with type 2 diabetes. Patients inadequately controlled on metformin were randomized to either anagliptin (100 mg twice daily, n = 92) or sitagliptin (100 mg once daily, n = 88)...

Clinical Trials Related to Metformin

Metabolic Effect of Metformin in Obese Insulin Resistant Adolescents With Normal Glucose Tolerance [Active, not recruiting]
The primary objective of this randomized, parallel group, double-blind, placebo-controlled study is to determine whether treatment with metformin enhances insulin sensitivity in a group of ethnically diverse obese insulin-resistant adolescents with normal glucose tolerance.

Drug Interaction With Metformin [Completed]
The purpose of the study is to determine the effect of metformin on dapagliflozin exposure and the effect of dapagliflozin on metformin exposure in healthy volunteers. Additionally, the safety and tolerability of dapagliflozin will be assessed in the presence and absence of metformin in healthy volunteers

Rosiglitazone-Metformin Combination Versus Metformin-Sulfonylurea Combination On Beta-Cell Function In Type 2 Diabetes [Active, not recruiting]
It has been shown in previous study that progressive glycemic deterioration was associated with progressive loss of b-cell function, measured by the decrease in plasma insulin levels, irrespective of the therapy used (diet, sulfonylureas or metformin).There is growing evidence that thiazolidinediones could have a positive action on the b-cell function. But it has not yet been demonstrated that they could protect from a deterioration in insulin secretion in the long term. So, it appears interesting to study the long term evolution of the b-cell function and the possible protection with rosiglitazone in patients with type 2 diabetes showing evidence of loss of b-cell function with metformin alone.

Efficacy and Safety of Prandial Inhalation of Technosphere/Insulin in Combination With Metformin or Technosphere/Insulin Alone Versus 2 Oral Anti-Diabetic Agents in Subjects With Type 2 Diabetes [Active, not recruiting]

To Compare the Effect of Liraglutide When Given Together With Metformin With the Effect of Metformin Given Alone and With the Effect of Glimepiride and Metformin Given Together [Active, not recruiting]
This trial is conducted in Europe, Oceania, Africa, Asia and South America.

This trial is designed to show the effect of treatment with liraglutide when adding to existing metformin therapy and to compare it with the effects of metformin monotherapy and combination therapy of metformin and glimepiride.

The 26 weeks double-blind period will be followed by an 18 months open label extension.
