About this trial

This is an interventional treatment trial for Type 2 Diabetes

Eligibility Criteria

20 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

Age 20-80 years inclusive. Type 2 diabetes BMI ≥30 kg/m2 Subjects on statins, ACE inhibitors, thiazolidenediones and antioxidants will be allowed as long as they are on stable doses of these compounds and the dosage in not changed during the course of study.

HbA1c ≤ 8.0%

Exclusion Criteria:

- Use of GLP-1 agonists or DPP-IV therapy in the last 3 months. History of Pancreatitis. Risk for pancreatitis, i.e., history of gallstones, alcohol abuse, and hypertriglyceridemia.

Subjects who are taking antiplatelet or anticoagulant medications will be excluded from the fat biopsy portion of the study.

Coronary event or procedure (myocardial infarction, unstable angina, coronary artery bypass, surgery or coronary angioplasty) in the previous four weeks Hepatic disease (liver function tests more than 3 times the upper limit of normal) Renal impairment (serum eGFR <30 ml/min) Any other life-threatening, non-cardiac disease Uncontrolled hypertension (BP > 160/100 mm of Hg) Congestive Heart Failure class III or IV. Use of an investigational agent or therapeutic regimen within 30 days of study Participation in any other concurrent clinical trial

Placebo

Linagliptin 5mg per day

Arm Description

Patients will be treated for 12 weeks with placebo once daily

Patients will be treated for 12 weeks with Linagliptin 5mg once daily.

Outcomes

Primary Outcome Measures

JNK-1 Protein in MNC
JNK-1 protein in MNC before and after linagliptin use as compared to placebo.

Secondary Outcome Measures

IL-1β mRNA Levels
Comparing IL-1B between Linagliptin group and placebo group based on the PCR test, between week 0 and week 12.
Oxidative Stress (as ROS Generation Level)
oxidative stress (ROS generation level) following linagliptin. ROS generation measurement by chemiluminescence of PMN cells
Insulin Sensitivity by Hyperinsulinemic-euglycemic Clamp
Insulin sensitivity is measured with HE clamp. Glucose Infusion Rate was titrated to maintain blood glucose concentration at the fasting glucose level. Plasma samples for glucose was obtained at 10-minute intervals starting 30 minutes before the clamp, to quantitate rates of whole-body glucose disposal. Difference from baseline at 12 weeks is calculated and compared to placebo arm
