Effect of Neo40 on PAD

October 14, 2016 updated by: HumanN

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.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Persons of at least 45 years of age
  • Persons with unilateral or bilateral PAD confirmed by a resting ankle-brachial index (ABI) <0.9
  • Persons with stable intermittent claudication for the previous 3 months
  • Persons with the ability to walk 1 to 12 minutes on a treadmill. The pre-randomization treadmill test is limited by exercise-induced leg pain, which is relieved by cessation of the test. Variability of maximum walking distances between 2 consecutive screening treadmill tests will be <10%.

Exclusion Criteria:

  • Persons with ischemic rest pain, ulceration or gangrene
  • Persons with history in the previous 3 months of acute coronary syndrome or revascularization involving the peripheral or coronary arteries
  • Persons with major amputation
  • Persons with malignancy within the previous 5 years (except for treated non-melanoma skin cancer)
  • Persons with proliferative retinopathy
  • Persons with uncontrolled hypertension
  • Persons with active inflammatory, infectious, or autoimmune diseases.
  • Persons taking taking phosphodiesterase inhibitors, organic nitrates and/or hydralazine

Active Comparator: Neo40 Supplement
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.
Dietary supplement: Neo40
Placebo Comparator: Placebo
A placebo product has been manufactured that looks, tastes and feels like the Neo40 active lozenge without the active ingredients
Dietary supplement: Placebo

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Skinner-Gardner treadmill protocol.
Time Frame: 3 months
The primary end point is the change at 3 months in the absolute claudication distance. Distance will be measured in meters walked on treadmill
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Endothelial function
Time Frame: 3 months
Secondary objectives are to evaluate endothelial function. EndoPAT score of 1.67 and below correlates to endothelial dysfunction.
