Impact of Plant Sterol Supplement on LDL-C Lowering in Low-to-Moderate Risk South Asian Patients

Phase 4

Completed

• Conditions: Cardiovascular Risk Factor
• Interventions: Drug: Plant Sterol

• Registration Number: NCT04030247
• Lead Sponsor: Stanford University

Brief Summary

The purpose of this study is to measure the incremental effectiveness of a twice daily plant sterol supplement in a population of South Asian patients who have low-to-moderate cardiovascular disease (CVD) risk.

Detailed Description

In this study, we aim to measure the LDL-C reducing impact of regular plant sterol supplementation added to a proven CVD reduction program for low-to-moderate risk South Asians who do not meet guideline-based criteria (2018 ACC/AHA Lipid Guidelines) for medical lowering of their LDL-C with an HMG CoA reductase inhibitor (statin) drug, and they are recommended to improve their lipid-risk profile through diet and exercise primarily. In addition, patients who may qualify for statin therapy, but are deemed to be intolerant of statins or who refuse lipid lowering medication may also qualify.

Exclusion Criteria

1. Subject has taken a prescription cholesterol-lowering medication in the past 1 month.
2. Subject has a known allergy or sensitivity to soy, corn, or other ingredients in the study product.
3. Subject is taking dietary supplements for cholesterol-lowering such as red yeast rice, niacin >100 mg/d or omega-3 fatty acid supplements providing ≥1000 mg/d eicosapentaenoic acid and/or docosahexaenoic acid. (Stable use of viscous fiber laxative ≤2 teaspoons/d is allowed.)

5. Individual has active angina, stable or unstable, requiring urgent cardiovascular functional risk stratification (stress testing or catheterization) or intervention. Or has congestive heart failure that is not compensated or in which the subject is not euvolemic, as determined by the treating MD.
6. Individual has a condition the Investigator believes would interfere with his or her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results or put the person at undue risk.
