Project title: Preservation of Beta-Cell Function in Type 2 Diabetes Mellitus

Human subjects IRB approved project number (where applicable): 1003-623

Animal subjects IRB approved project number (where applicable):

Project Type (patient-based research, animal-based research, or basic research; this characterization is only to permit a general classification for grouping similar types of projects)

This study is patient-based.

Brief Description of Project:

The purpose of the study is to find out if taking insulin shots along with metformin is better at preventing beta-cell decline in type 2 diabetic patients than a combination of three different oral hypoglycemic agents.
The study has a 3-month run-in period in which all patients take metformin and insulin injections. Following the run-in period participants are randomized to metformin and insulin injections, or metformin, glyburide and Actos (pioglitazone). The actual treatment period lasts 18 months. Participants are required to attend visits once a month for the first 9 months of the study, and once every three months for the last 12 months. Beta-cell function is assessed using a Mixed Meal Challenge Test which is performed at 6-month intervals during the study.

Project title: The Role of Platelet Activating Factor-Acetylhydrolase in Complications and Response to Treatment in Diabetes.

Human subjects IRB approved project number (where applicable): 072004-051

Animal subjects IRB approved project number (where applicable):

Project Type (patient-based research, animal-based research, or basic research; this characterization is only to permit a general classification for grouping similar types of projects)

This study is patient-based.

Brief Description of Project:
The purpose of this study is to investigate the role of an enzyme, Platelet Activating Factor-Acetylhydrolase (PAF-AH), in patients with diabetes. PAF-AH is associated with lipoproteins and is a marker of inflammation and atherosclerosis. However, its relevance in diabetes is unknown. Participants will be given a brief physical exam and asked questions about their general health and diabetes. Fundoscopic exam and ankle-brachial blood pressure measurement will be preformed as well. A small sample of blood will be taken for laboratory analysis. We will measure other inflammation markers with enzyme-linked immunosorbent assay (ELISA) in our lab. We will then evaluate the correlation of PAF-AH with diabetic complications and glycemic control.

Project title: A Multicenter, Randomized, Double Blind, Placebo-Controlled Multiple Doses Study of the Efficacy and Safety of AS-3201 in Patients with Diabetic Sensorimotor Polyneuropathy.

Human subjects IRB approved project number (where applicable): 092004-009

Animal subjects IRB approved project number (where applicable):

Project Type (patient-based research, animal-based research, or basic research; this characterization is only to permit a general classification for grouping similar types of projects)

This study is patient-based.

Brief Description of Project:
The purpose of this study is to test the safety, potential usefulness and the best dose of an investigational drug, AS-3201, compared to a placebo in patients with Type 1 or Type 2 diabetic sensorimotor polyneuropathy. AS-3201 is a novel compound called an aldose-reductase inhibitor. Following a nerve conduction study to test the functional ability of the nerves, a participant will be randomized to 10 milligrams, 20 milligrams, or 40 milligrams of AS-3201 or a placebo for a one year period. Patients will be monitored throughout the year and will complete a second nerve conduction study at the termination of the study to determine if the functional ability of the nerves improves over the course of the study.

Project title: Potential Causes of Weight Gain with Intensive Insulin and Combination Therapy in Type 2 Diabetes.

Human subjects IRB approved project number (where applicable): 0403-218

Animal subjects IRB approved project number (where applicable):

Project Type (patient-based research, animal-based research, or basic research; this characterization is only to permit a general classification for grouping similar types of projects)

This study is patient-based.

Brief Description of Project:
The purpose of this research is to determine the causes of weight gain with intensive insulin treatment in type 2 diabetes mellitus and where the weight is distributed throughout the body. This study will also evaluate the effects of insulin on the heart and the liver. Patients will be treated with intensive insulin therapy in combination with pioglitazone or a placebo for six months. At the beginning and termination of the study, participants will complete a Mixed Meal Test to determine how well the pancreas is functioning. Magnetic resonance imaging (MRI) will be used to determine fat distribution in the abdominal cavity and in the thighs. Participants will then be randomized to insulin therapy in combination with pioglitazone or a placebo. Treatment will continue for six months. During the study period, several tests will be performed including skinfold measurement. A second mixed meal test and MRI will be performed at the termination of the study.
