Efficacy Evaluation of Different Medication Combination in Type 2 Diabetes Treatment.

2014-08-27 03:15:36 | BioPortfolio


The purpose of this study is to compare the effectiveness of two different kinds of diabetes medications, insulin detemir (Levemir) and exenatide (Byetta), in improving blood sugar levels with little or no weight gain in patients with type 2 diabetes who are not well controlled on two or more oral (by mouth) diabetes medications. Both medications are given by injection with a very small needle just below the surface of your skin (called subcutaneous injection). The medication that you inject will be in addition to your oral medications.


Finding a safe and effective method of improving blood glucose (BG) control without weight gain is one of the major goals of diabetes research. Previous research studies have shown that Levemir and Byetta are safe and effective medications in the treatment of type 2 diabetes. Both drugs have been approved by the U.S. Food and Drug Administration (FDA) for the treatment of type 2 diabetes. The use of Levemir and Byetta in combination in this study, is investigational, meaning it is not approved by the FDA for this use. However, the FDA has allowed the use of Levemir and Byetta in combination in this study of safety and effectiveness in improving blood sugar levels with little or no weight gain in people with type 2 diabetes.

Levemir is a long acting insulin that is usually taken once a day at bedtime and can last for up to 24 hours. Unlike most insulins that lower blood glucose levels, but cause weight gain, clinical research trials suggest that Levemir may lower blood glucose levels without causing weight gain and may even result in weight loss.

Byetta is not insulin, but improves blood glucose control by mimicking the action of hormones in the gastrointestinal tract called incretins. The incretin hormones trigger the release of insulin from the pancreas and allow insulin to work more effectively in the body. Byetta also delays the movement of food from the stomach into the small intestine. As a result, people taking Byetta may feel "full" faster and longer, so they eat less. The most common side effect with Byetta is mild to moderate nausea, which improves with time in most people. Clinical research trials that have studied the effects of Byetta have shown that, in addition to lowering blood glucose levels, the use of Byetta resulted in weight loss.

There have been no previous studies that have compared Levemir to Byetta in patients who have failed to achieve blood glucose goals with two or three oral diabetes medications.

Medical and Biotech [MESH] Definitions

A syndrome with excessively high INSULIN levels in the BLOOD. It may cause HYPOGLYCEMIA. Etiology of hyperinsulinism varies, including hypersecretion of a beta cell tumor (INSULINOMA); autoantibodies against insulin (INSULIN ANTIBODIES); defective insulin receptor (INSULIN RESISTANCE); or overuse of exogenous insulin or HYPOGLYCEMIC AGENTS.

Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS. It can be caused by the presence of INSULIN ANTIBODIES or the abnormalities in insulin receptors (RECEPTOR, INSULIN) on target cell surfaces. It is often associated with OBESITY; DIABETIC KETOACIDOSIS; INFECTION; and certain rare conditions. (from Stedman, 25th ed)

An insulin preparation that is designed to provide immediate and long term glycemic control in a single dosage. Biphasic insulin typically contains a mixture of REGULAR INSULIN or SHORT-ACTING INSULIN combined with a LONG-ACTING INSULIN.

Insulin formulation containing substance which delays or retards time period of the absorption of insulin.

A preparation of insulin and zinc chloride in the form of a crystalline suspension. Typically the duration of ultralente insulin activity lasts between 18-30 hours after dosage.
