About this study

Official title: "A Randomized, Double Blinded, Placebo Controlled, Parallel Arm, Study to Evaluate the Improvement in Glycemic Control After Daily Administration of Chromium Picolinate and Biotin in Patients With Type 2 Diabetes Mellitus"

The purpose of the proposed work is to assess the effects of a dietary supplement, containing chromium (600 mcg per day) provided by chromium picolinate and biotin (2 mg per day) on glycemic control in type 2 diabetes. Specifically, this study will assess whether use of the supplement will lower the post-prandial rise in blood glucose experienced after ingestion of a 75g carbohydrate load, relative to placebo, in type 2 diabetic patients. The study will also assess the chronic effects of supplementation over a 4-week period (relative to placebo) on fasting plasma levels of glucose, insulin, lipids and lipoproteins.

Read the detailed description

The purpose of this work is to assess the effects of a dietary supplement, containing chromium (600 mcg per day) provided by chromium picolinate and biotin (2 mg per day) on glycemic control in type 2 diabetes who are currently taking an oral antidiabetic agent (OAD) and failing therapy with OADs. Subjects entering the trial must have a HbA1c >/= 7.0% and have an OGTT >/= 200 mg/dL at 2 hours post consumption of a 75 g glucose beverage. The study is an acute 30 day intervention in conjunction with the subject's current OADs and standard of care in comparison to placebo.

Specifically, this study will assess whether use of the supplement will lower the post-prandial rise in blood glucose experienced after ingestion of a 75g carbohydrate load, relative to placebo, in type 2 diabetic patients as measured by the area under the curve for glucose (AUCg). The study will also assess the acute effects of supplementation over a 4-week period (relative to placebo) on fasting plasma levels of glucose, fructosamine, insulin, lipids and lipoproteins.

Questions about this trial

What is this clinical trial studying?

A study testing Chromium Picolinate (600 mcg Cr+3) + biotin (2 mg) in people with Diabetes Mellitus, Type 2, run by Nutrition 21, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Mar 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary(baseline versus final): AUCg as recorded from a 2-hour OGTT with 75 g glucose beverage; fructosamine; fasting plasma glucose.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2006.
