Treatments januvia (sitagliptin) 100 mg, placebo
Sponsor Kaleida Health

Start date March 2008
End date December 2013
Trial size 40 participants
Trial identifier NCT00659711, 1931 Januvia


Sitagliptin is a new oral hypoglycemic anti-diabetic drug used either alone or in combination with metformin or a thiazolidinedione for control of type 2 diabetes mellitus. Sitagliptin has been shown to have fewer side effects in the control of blood glucose values.

Obesity and diabetes are states of increased inflammation and can influence the free radicals and inflammatory markers (chemicals in the blood which increase due to inflammation in the body) and are also major risk factors for atherosclerotic disease. In this study we want to see the effect of sitagliptin on these markers. We believe that Sitagliptin may exert an anti-inflammatory effect in the human. The purpose of this study is to determine if the addition of sitagliptin to diabetic patients will provide added benefit. We believe that sitagliptin provides these added benefits by suppressing free radicals (charged substances that cause damage to the body) and inflammation.

Primary Outcomes

To investigate that therapy with sitagliptin orally daily (100 mg) for 12 weeks decreases reactive oxygen species (ROS) generation by MNC, protein and mRNA expression of p47phox subunit of NADPH oxidase, in MNC's of obese type 2 diabetic patients
time frame: 12 weeks

Secondary Outcomes

oxidative stress
time frame: 12 weeks
