The purpose of the study is to determine whether E1 and G1 are safe and effective in the treatment of type 2 diabetes.
Type 2 diabetes is the most common form of diabetes. The disease is characterised by insulin resistance and a compensated state of hyperinsulinemia. In most individual, hyperglycemia results from a failure of pancreatic beta cells insulin secretory capacity to adequately compensate for insulin resistance in peripheral tissues. Treatment for type 2 diabetes is achieved by dietary control, or a combination of diet and oral hypoglycemic agents or insulin. As the disease progress, many type 2 diabetic patients eventually require insulin as primary therapy to achieve glycemic control.
Recent diabetic research has increasingly focused on pancreatic islet cell replacement, either by islet cell transplantation or by endogenous regeneration of islet cells. During fetal development, islet precursor cells proliferate and differentiate into mature beta cells capable of producing insulin. This process is known as islet cell neogenesis. Islet cell neogenesis normally ceases around birth, however, the adult pancreas still retains significant potential for islet regeneration, as shown by tissue repair following pancreatic injury. Pre-clinical studies have shown that E1 and G1 can re-establish islet cell neogenesis and increase insulin production in diabetic animal models. In type 2 diabetic patients, treatment with E1 and G1 may result in islet cell regeneration. This therapeutic approach may improve beta cell function, restore the loss of insulin secretory capacity and also benefit patients on oral hypoglycemic agents by delaying insulin use.

|Type 2 Diabetes||Drug: E1 and G1||Phase 1|
In this study, 30 type 2 diabetic patients requiring oral hypoglycemic therapy with Metformin and/or Thiazolidinedione will be randomized. Twenty (20) patients will be randomized to receive active study medication and 10 patients will be randomized to receive vehicle control. After undergoing screening procedures, potential patients will enter a 14 day baseline phase where baseline data will be collected. Pending successful completion of the baseline phase, patient will enter a 28-day treatment phase where they will be randomized to receive either once daily subcutaneous injections of E1 plus G1, as separate injections or once daily subcutaneous injections of vehicle control (as 2 separate injections). Patients will receive once daily doses in the morning after breakfast for a period of 28 days. Upon completion of treatment, all patients will continue in the follow-up phase for an additional 6 months and will return to the clinic for monthly visits. Throughout the study, patients will remain on their current oral hypoglycemic therapy with Metformin and/or Thiazolidinedione and will maintain a diary record of blood glucose levels.
The body's ability to control glucose will be assessed by oral glucose tolerance test (OGTT). After an overnight fast, patients will be asked to drink a solution containing a known amount of glucose. Blood samples for glucose and insulin measurements will be obtained before the patients drink the glucose solution, and again 30 minutes, 60 minutes and 2 hours after the glucose is consumed. This test will be performed at frequent intervals during the study.
