Peripheral Artery DiseaseNCT02934438
Effect of Neo40 on PAD
A study testing Neo40 in people with Peripheral Artery Disease, run by HumanN.
Trial summary
Reduced nitric oxide (NO) availability is a hallmark of a number of cardiovascular diseases (CVD) including peripheral artery disease (PAD). The investigators will test the hypothesis that sub-chronic NEO40™ supplementation will improve vascular NO function and improve intermittent claudication in patients with PAD.

About this study
Official title: The Effects of an Oral Nitric Oxide Lozenge on Peripheral Artery Disease
Reduced nitric oxide (NO) availability is a hallmark of a number of cardiovascular diseases (CVD) including peripheral artery disease (PAD). The investigators will test the hypothesis that sub-chronic NEO40™ supplementation will improve vascular NO function and improve intermittent claudication in patients with PAD. Using a prospective, double blind, placebo controlled experimental design in 30 patients, graded treadmill tests will be performed at baseline and after 3 months after randomization, according to the Skinner-Gardner protocol. Initial claudication distance (ICD) and absolute claudication distance (ACD) will be recorded. Two consecutive treadmill tests will be performed within 1 week at baseline (before administration of study drug); and 2 test will be performed at 3 months. Functional status will also be assessed by the Walking Impairment Questionnaire and the Health Status Survey SF-36 questionnaire (SF-36). Vascular function will be assessed with the use of a Vendys® vascular reactivity (endothelial function) test (Endothelix Inc). Digital pulse amplitude will be assessed using sensor probes on the index finger during reactive hyperemia. Blood will be collected for measurement (by Neogenis) of plasma levels of nitrite and nitrate at baseline and at the completion of the study. Based on previously published trials using this NO technology, the investigators predict that the group receiving the active supplement will exhibit an improvement in claudication distance and all measures of vascular function after 3 months.

Neo40Dietary supplement
PlaceboDietary supplement
| Study group | Role | What they receive |
|---|---|---|
| Neo40 Supplement | Active comparator | Utilizing intellectual property developed out of the University of Texas Health Science Center in Houston, Neo40 is a GMP certified, over the counter, all natural formulation that provides a system for generating NO in an endothelium-dependent and independent manner. The NEO40™ Daily™ product ingredients list and packaging was submitted to FDA Office of Compliance by Neogenis Labs, Inc. for use as a dietary supplement. It is made up of Beet root extract, hawthorne berry, Vitamin C, L-citrulline and sodium nitrite. The lozenges utilize natural product chemistry activated by the saliva to generate authentic NO gas in the oral cavity through the one-electron reduction of nitrite. This product's formulation was designed to be a quick dissolve that melts in the mouth within four to five minutes. Receives: Dietary Supplement: Neo40 |
| Placebo | Placebo comparator | A placebo product has been manufactured that looks, tastes and feels like the Neo40 active lozenge without the active ingredients Receives: Dietary Supplement: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Skinner-Gardner treadmill protocol.
The primary end point is the change at 3 months in the absolute claudication distance. Distance will be measured in meters walked on treadmill
Measured: 3 months
Secondary outcomes (1)
Endothelial function
Secondary objectives are to evaluate endothelial function. EndoPAT score of 1.67 and below correlates to endothelial dysfunction.
Measured: 3 months
