Insulin Receptor Substrate 1 (IRS-1) Regulation in Insulin Resistance
Type 2 Diabetes MellitusThe study is being conducted to find out why too much fat in your blood stream may cause insulin resistance in your muscles. Insulin is the hormone, produced normally by your body, which causes your blood sugar to return to normal after you eat.

A Multiple-Ascending Dose Study in Type 2 Diabetes Mellitus Patients
Diabetes MellitusType 2The study drug LY2393910 is being evaluated as a possible treatment for diabetes. The primary purpose of a patient's participation in this study is to help answer the following research question(s), and not to provide treatment for diabetes: The safety of LY2393910 and any side effects that might be associated with it following 2 weeks of doses How long it takes the body to absorb and remove LY2393910 following dosing over 2 weeks How daily dosing of LY2393910 affects blood levels of sugar (glucose), insulin and other naturally occurring substances in your body How daily dosing of LY2393910 affects the cells that produce insulin Any differences in the above between LY2393910 taken as daily doses in the morning or in the evening

Effect of Pioglitazone on TIMP-3 and TACE in Type 2 Diabetes
Type 2 DiabetesBackground: Pioglitazone has been shown to have potent anti-inflammatory as well anti-atherosclerotic effects. However, the mechanisms by which pioglitazone exerts these effects are not clear. The investigators propose that Tissue Inhibitor of MetalloProteinase-3 (TIMP-3) and TNF-alfa converting enzyme (TACE) play a major role in pioglitazone mediated improvement in insulin sensitivity and endothelial function. In animal models, low dose pioglitazone inhibits lesion progression and matrix metalloproteinase expression in advanced atherosclerotic plaques. The investigators believe that a lower dose of Pioglitazone will also have anti-inflammatory effects. Aim: To examine the effect of low dose Pioglitazone (15mg/day) on TIMP and TACE in Pioglitazone mediated improvements in insulin sensitivity. Methods: Thirty subjects with T2DM will participate in following studies: (i) oral glucose tolerance test (OGTT); (ii) Dual energy absorptiometry(DXA) for body fat content, (iv) skeletal muscle biopsy. Subjects will be randomized to receive either placebo or pioglitazone for 24 weeks. The investigators will study the effect of Pioglitazone on (1) TIMP and TACE substrate activity in skeletal muscle, adipose tissue, mononuclear cells, and their relationship to insulin sensitivity and vascular reactivity, other adipocytokines- resistin, TNF-α and Visfatin; (2) markers of inflammation and atherosclerosis- C-reactive protein, VCAM-1 (vascular cell adhesion molecule 1), ICAM-1 (Intercellular Adhesion Molecule 1), endothelin 1, E-selectin, P-selectin, TNFrecI (Tumor Necrosis Factor Receptor I), TNFrecII (Tumor Necrosis Factor Receptor II), IL-6 (Interleukin 6) receptor.

A Clinical Pharmacology Study of Saxagliptin in Patients With Type 2 Diabetes Mellitus
DiabetesThe purpose of this study is to evaluate the pharmacokinetics and pharmacodynamics of saxagliptin administered before breakfast for 14 consecutive days in patients with type 2 diabetes mellitus.

The Study of Exenatide Action on Vessel Function in Type 2 Diabetes and Prediabetes
Type 2 Diabetes MellitusThe purpose of this investigation is to evaluate whether exenatide, a type 2 diabetes medication, will improve the function of the innermost part of the arterial wall called the endothelium after a fat-enriched meal and to determine how this occurs. The results of this study will help to determine and understand a novel action of this group of diabetes medications based on the action of naturally occuring gut substances called incretins. This may have a significant impact on cardiovascular health in patients with early and longstanding diabetes.

Safety, Tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) Assessment of LIK066 in Healthy...
Type 2 Diabetes Mellitus (T2DM)This study will assess safety, tolerability, and effect of LIK066 on blood glucose in healthy subjects and in patients with T2DM.

Outreach for Diabetes Cure
Type II DiabetesUsing a socioeconomic, race/ethnic, and gender-diverse sample of patients who receive diabetes care from a University of Colorado Hospital (UCH) primary care provider (PCP), carry out a randomized-controlled trial of usual care versus an outreach intervention designed to increase guideline concordance with American Diabetes Association (ADA) recommendations for blood pressure, Low-density lipoprotein (LDL), and glycosylated hemoglobin (A1c) goals, referrals for retinal exams, and aspirin therapy.Primary hypotheses: The proportion of patients meeting goal will be 10% higher in the intervention compared with control group in the following domains: 1. LDL<100 mg/dL; 2. A1c<7.0%; and 3. Systolic blood pressure<130 mm Hg or diastolic blood pressure<80 mm Hg.

Diet Oil Induced Stimulation of GLP-1
Type 2 Diabetes MellitusActivation of G protein-coupled receptor GPR119 stimulates glucagon-like peptide-1 (GLP-1)release from the intestinal L-cells. Previously, administration of 2-oleyl-glycerol (2-OG) to humans significantly increased plasma GLP-1. In the present study we want to test the effect in patients with type 2 diabetes. The hypothesis is that we will expect to find a significant increased plasma GLP-1 following a meal containing of 2-OG when compared to meals containing of olive oil or carbohydrates alone.

A Study of PF-05175157 in Healthy Volunteers and Type 2 Diabetic Patients
Diabetes MellitusType 2The primary purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of multiple ascending doses of PF-05175157 in healthy volunteers and patients with type 2 diabetes mellitus.
