Evaluation of Oral Alpha-Cyclodextrin for Decreasing Serum Cholesterol
Completed · Phase 2 · Has a placebo group
Conditions studied: Cardiovascular Disease
In brief
Background: * Cardiovascular disease (CVD) is a leading cause of death in developed countries. Although statin-type drugs are currently the most effective therapeutic agents for reducing CVD risk. One possible complementary approach involves the use of soluble dietary fibers that are known to reduce blood cholesterol levels. However, analysis has shown that most soluble fibers reduce total cholesterol levels by relatively small amounts. * Alpha-Cyclodextrin (Alpha-CD), also sold in commerical form, is a soluble fiber derived from corn that is used as an ingredient in many foods, such as bread rolls, crackers, juices, and reduced fat spreads. It is added to food primarily as a fiber supplement but is also used to stabilize flavors, colors, vitamins, and fatty acids. Studies in animals and humans have shown that Alpha-CD may help to improve insulin resistance and lower LDL cholesterol levels with no apparent side effects. More research is needed to determine the effect of Alpha-CD on total cholesterol levels in healthy volunteers. Objectives: \- To determine the effect of oral Alpha-CD on total cholesterol in a nondiabetic population.

- Subjects currently following any low-fat (< 20%) diet.
- Subjects that routinely consume less than 3 meals/snacks per day
- Subjects taking the following medications, which may show reduced absorption with alpha-CD or may otherwise interfere with the study will be excluded: soluble fiber supplements, BAS, plant sterol supplements, antibiotics, anticoagulants, anticonvulsants, antiarrhythmics , cyclosporine, mycophenolate, synthroid, vitamin A, E and K and or any drug that is necessary to take with a meal. If any of these medications are initiated during the study, the subjects will be instructed to discontinue the use of the alpha-CD or placebo pills and to withdraw from the study.

- Subjects initiating new medications or patients on multiple medications may also be excluded.
- Patients with type I or type II diabetes.
- Subjects currently taking alpha-CD in its commercial form.
- Volunteers may also be excluded, if in the opinion of the study investigators, they have some other condition or disorder that may adversely affect the outcome of the study or the safety of the volunteer.
