Study Title Principal Investigator
Beta Cell Restoration Through Fat Mitigation
BetaFat is a 2-arm, unblinded study to compare gastric banding to treatment with metformin over a 24-month period in moderately obese adults with pre- or mild type 2 diabetes. The primary outcome will be change in β-cell compensation for insulin resistance, which the investigators will compare between groups. Secondary analyses will include other potential markers of β-cell health and potential mediators of treatment-specific effects. The main focus will be on mediators related to obesity. Clinically, the project will serve as a test of concept for use of gastric banding relatively early in the spectrum of obesity and β-cell disease. Biologically, the results will provide crucial information on potential mediators of β-cell failure and its arrest or reversal in the context of obesity. Those mediators will guide the development of more effective treatment and monitoring for the β-cell disease that causes type 2 diabetes.

Post Approval Study of the TS (Threshold Suspend) Feature With a Sensor-Augmented Pump System Supplemented With Commercial Patient Data
Multi-center trial is initiated to observe the Threshold Suspend (TS) feature with a sensor-augmented insulin pump (Medtronic MiniMed® 530G insulin pump) in patients 16 and older with insulin requiring diabetes over a period of one year.

A Randomized Phase 2, Double-blind, Placebo-controlled, Treat-to-Target, Parallel-group, 3-arm, Multicenter Study to Assess the Efficacy and Safety of Canagliflozin as Add-on Therapy to Insulin in the Treatment of Subjects with Type 1 Diabetes Mellitus
Canagliflozin (CANA) is an oral antihyperglycemic agent (AHA) approved for the treatment of subjects with Type 2 Diabetes Mellitus (T2DM). In subjects with T2DM, CANA lowers blood glucose by an insulin-independent mechanism and has an intrinsic low risk of hypoglycemia. In subjects with T1DM the addition of CANA to intensive insulin therapy is expected to lead to less insulin requirement which is expected to lead to a reduced insulin dose requirement, weight gain, glucose variability and low the risk of hypoglycemia. The primary objective of this study is to assess the effect of CANA 100 mg and 300 mg compared with placebo on the change in HbA1c and body weight after 18 weeks of treatment. This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter, interventional study of CANA in male and female subjects between the ages of 25 years to 65 years, inclusive, with a diagnosis of T1DM for at least 1 year, and inadequate glycemic control (ie, HbA1c of 7.0% to 9.0%) on basal plus bolus insulin at screening. Approximately 330 subjects will be randomly assigned in this study (20 at the USC site), with approximately 110 subjects randomized per treatment group. The primary hypothesis will be assessed using a composite primary endpoint: proportion of subjects with HbA1c reduction 0.4% and no increase in body weight. Assuming the proportion of subjects meeting the composite criteria is 20% for placebo and 40% for each CANA dose, and assuming a 2-sided family-wise Type I error rate of 0.05, it is estimated that a sample size of 100 randomized subjects per group will be required to achieve 84% power for the comparison of each CANA dose to placebo. A modestly larger sample size (110 subjects per arm) will be randomized to each treatment arm. The modified intent-to-treat (mITT) analysis set includes all randomized subjects who have received at least 1 dose of double-blind study medication. The per-protocol (PP) analysis set consists of all mITT subjects who complete the 18-week double-blind treatment phase, and have no major protocol deviations that may affect the interpretation of the primary efficacy endpoint. The completers analysis set consists of all mITT subjects who complete the 18-week double blind treatment period. The primary efficacy endpoint will be proportion of subjects with HbA1c reduction 0.4% and no increase in body weight after 18 weeks of treatment. The primary efficacy endpoint will be analyzed longitudinally using a generalized linear mixed model. The model will include the fixed, categorical effects of treatment, stratification factor (use of CSII vs MDI), visit, and treatment-by-visit interaction, as well as the continuous, fixed covariates of baseline HbA1c, baseline body weight, and baseline-by-visit interactions. An unstructured covariance will be used to model the within-patient errors. The odds ratio and 2-sided 95% confidence interval (CI) for the treatment comparison at Week 18 (CANA vs placebo) will be estimated based on this model. As a sensitivity analysis, the last-observation-carried-forward method will be applied when the Week 18 values are missing. The odds ratio will be assessed by a logistic regression model with terms for baseline HbA1c, baseline body weight, treatment and stratification factor.

A Phase III, Double-blind, Randomized, Placebo-controlled, Multicenter Study to Asses the Safety and Efficacy of VM202 to Treat Chronic Nonhealing Foot Ulcers in Diabetic Patients With Concomitant Peripheral Arterial Disease (PAD)
A phase III, randomized, double-blind, placebo-controlled, multicenter, 7-month study designed to assess the safety and efficacy of intramuscular (IM) injections in the calf of VM202 in patients with chronic nonhealing foot ulcers. Three hundred patients will be randomized in a 2:1 ratio of VM202 or placebo injections: - Active -VM202 + standard of care - 200 patients - Control - Placebo (VM202 Vehicle) + standard of care - 100 patients
