Clinical Trial Summary

The goal of this application is to evaluate the safety and efficacy of atorvastatin as a potential treatment to preserve beta cell function in children and young adults with newly diagnosed type 1 diabetes (T1DM).

Description:

Type 1 diabetes is an autoimmune disease that is characterized by destruction of the insulin-producing beta cells of the pancreas. T1DM therapy requires insulin administration, either by multiple daily injections or by insulin pump. However, in many patients, blood sugar control remains suboptimal and complications develop that shorten life expectancy and severely impact quality of life. At the time of diagnosis, most patients still have significant residual beta cell function. Previous research has shown that weakening the immune system's attack on the pancreatic beta cells may help to preserve or potentially increase insulin production.

Preliminary studies have shown that members of the statin family of medications, including atorvastatin (Lipitor®), preserve beta cell function in a mouse model of type 1 diabetes. These finding suggest that use of atorvastatin in combination with insulin therapy may delay and potentially reverse the destruction of beta cells in patients who have recently developed type 1 diabetes. Atorvastatin (Lipitor®) is approved for use in adults and children (>10 years of age) who have elevated blood cholesterol levels. This study will examine whether atorvastatin (Lipitor®) may also help the body preserve insulin production in patients with newly diagnosed (within 8 weeks) type 1 diabetes.

Patients will be randomly assigned to take either atorvastatin (Lipitor®) or placebo. Two out of every 3 patients will receive atorvastatin and 1 out of 3 will get placebo. As this is a double-blinded study, neither the care team nor the patient will know if they are actually taking atorvastatin (Lipitor®). Patients who have given consent to participate in the study and pass the required screening tests will take the assigned treatment every day for 12 months. All patients will begin taking 10 mg once daily, the recommended starting dose. After 4 weeks, the dose will be increased to 20 mg. In addition to a high standard of diabetes care and the medication, patients will have blood tests during 7 visits over an 18 month period.

Primary	4-hour C-peptide Area Under the Curve (AUC) in Response to Mixed Meal (MMTT).	C-peptide measurements collected over a 4 hour period (0, 30, 60, 90, 120, 150, 180, 210 and 240 minutes)after a Mixed Meal Tolerance Test. The area under the curve from these combined measurements is calculated and the unit of measure is nanogram*minutes/ml.	0, 30, 60, 90, 120, 150, 180, 210 and 240 minutes	Yes
Secondary	•2-hour and 4-hour C-peptide AUC After MMTT. •Hemoglobin A1c •Mean Daily Insulin Dose Per kg Body Weight for 7 Days •Mean Blood Glucose (BG), Number of Preprandial BG > 160 mg/dL or < 70 mg/dL, and Postprandial BG >200 mg/dL	for the C-peptide AUC measurements collected over a 2 or 4 hour period (with 30 minute intervals)after a Mixed Meal Tolerance Test. The area under the curve from these combined measurements (from 0 to 120 or 0 to 240 minutes) is calculated and the unit of measure is nanogram*minutes/ml.; Mean daily insulin dose is calculated from a logbook maintained by the subjects for one week prior to study visits.	baseline, 1,3,6,9,12,18 months	No
