Efficacy and Safety Study of Chromium Picolinate + Biotin on Glucose and Cholesterol Control in T2DM
To evaluate the effect of the combination of chromium picolinate (600 μg Cr) + biotin (2 mg) versus placebo on glycosylated hemoglobin (HbA1c), lipid profiles (Total-C, HDL-C, LDL-C, TGs, TG/HDL ratio, etc), and pharmacoeconomic outcomes as measured at the Baseline Visit and 90 days later at the Final Visit. Secondarily, to measure the effect of chromium picolinate (600 μg Cr) + biotin (2 mg) versus placebo on patient quality of life, fasting and post-prandial blood sugar levels, fasting insulin, and anti-hyperglycemic medication usage.
There will be an Initial Pre-Screening Contact, two office visits (Baseline and Final), and two mid-study phone contacts with the subject during the course of the study. Volunteers will take either chromium picolinate (600 μg Cr) + biotin (2 mg) (n=400) or placebo (n=200) once daily just prior to the morning meal for 90 days. Assessments for glycosylated hemoglobin, lipid profiles, and quality of life will be taken at the Baseline Visit. After 90 days another set of assessments will be taken at the Final Visit for comparison with the baseline values. All subjects will under go a brief physical exam, a medical history assessment, and a comprehensive concomitant medications assessment as well as provide blood and urine samples at the baseline and final visits to ensure subject safety is maintained. The subject will be contacted, by a central call center, between visits at Day 30 and Day 60 to ensure study compliance by reminding the subject to take all doses of study product, perform the daily blood glucose monitoring, and complete the study diary daily.

Medical and Biotech [MESH] Definitions
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.
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).
Diabetes Mellitus, Type 1
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.
Diabetes Mellitus, Lipoatrophic
A type of diabetes mellitus that is characterized by severe INSULIN RESISTANCE and LIPODYSTROPHY. The latter may be generalized, partial, acquired, or congenital (LIPODYSTROPHY, CONGENITAL GENERALIZED).
A life-threatening complication of diabetes mellitus, primarily of TYPE 1 DIABETES MELLITUS with severe INSULIN deficiency and extreme HYPERGLYCEMIA. It is characterized by excessive LIPOLYSIS, oxidation of FATTY ACIDS, production of KETONE BODIES, a sweet smell to the breath (KETOSIS;) DEHYDRATION; and depressed consciousness leading to COMA.
