NCT ID: NCT05595915 Phase: PHASE1 Status: COMPLETED Enrollment: 32 Completion: 2025-11-22
Conditions
Aging, Endothelial Dysfunction, Senescence
Interventions
COMP-4
Summary
In a young and healthy person, the production of nitric oxide (NO) by the endothelium, the inner lining of the blood vessel, is responsible for a) the ability of the blood vessel to dilate so it can increase its blood flow and b) act as an anti-clotting product to prevent blood clotting in those vessels. Under physiological stress either due to the development of a disease such as diabetes or simply from aging, the endothelial cells can be impacted and become dysfunctional thereby impairing their ability to make NO and even promote the development of blood clots. When such endothelial dysfunction occurs, it may be a precursor for the future development of cardiovascular (CV) disease like hypertension or even coronary artery disease later on in life in these patients. Therefore, the ability to somehow enhance the local production or availability of NO within such affected blood vessels in patients identified as prone to endothelial dysfunction could play a positive role in either preventing or delaying the onset of endothelial dysfunction and subsequent CV disease in such patients.
COMP-4 is a safe, clinically available, well tolerated oral supplement that has been shown in the lab to increase NO production in a number of differing tissues including human vascular endothelial cells. In this proposed human study, the investigators plan on recruiting healthy, young participants willing to take COMP-4 for a 14 day period in whom the investigators will measure in a non-invasive way - by the use of ultrasound - the effect of COMP-4 on its ability to improve blood flow in one of the major blood vessels of the upper arm. In addition, the investigators will also determine whether COMP-4 will be capable of lowering in the blood the levels of two of the most studied inflammatory markers associated with endothelial dysfunction, IL-8 and PAI-1.
Primary Outcome
To study the effect of short-term use of daily COMP-4 on flow mediated dilation (FMD) of the brachial artery in young, generally healthy men and women.
