Efficacy and Safety of Cycloset® Compared With Placebo When Added to Metformin

2014-07-24 14:22:09 | BioPortfolio


The purpose of this study is to investigate the efficacy and safety of Cycloset® and placebo when added to metformin monotherapy (at least 1000 mg/day for 3 months prior to screening) in persons with type 2 diabetes mellitus who are not adequately controlled on metformin therapy alone.


In the previously conducted Phase III clinical trials, Cycloset® (up to a maximum dose of 4.8 mg/day), administered either as monotherapy or combined with sulfonylurea therapy, significantly reduced HbA1c, fasting and post-prandial glucose and fasting and post-prandial triglycerides in obese individuals with type 2 diabetes mellitus. Clinical studies that combined Cycloset® with metformin were not as part of the original Cycloset® clinical program because metformin was not commercially available in the United States at the time that the studies were initiated. The present study is designed to investigate the efficacy and safety of Cycloset® compared to placebo when added to metformin monotherapy in persons with type 2 diabetes mellitus who are not adequately controlled on metformin therapy alone.

A sufficient number of individuals will be screened to enroll up to 326 subjects;approximately 276 subjects are expected to complete treatment through study termination (Week 26). The study population will consist of individuals currently treated with metformin, for at least 3 months prior to the study start. Subjects who have ever received exogenous insulin therapy as part of an outpatient diabetes treatment regimen are to be excluded, as are those taking oral anti-diabetic agents other than metformin within 3 months of screening (e.g., sulfonylureas, thiazolidinediones,alpha-glucosidase inhibitors, or meglitinides). Subjects may be male or female(surgically sterile, postmenopausal, or using appropriate contraceptive methods if of childbearing potential), age 18 to 75 years, inclusive, and are to have a screening HbA1c value of ≥ 7.5% and <11.0% and a screening body mass index (BMI) in the range of 25 kg/m2 to 42 kg/m2, inclusive.

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
