About this study

Official title: Phase 2 Study of the Effect of a Nutritional Supplement and Exercise on Human Stem Cells

The purpose of this study is to see if an investigational supplement called NutraStem® will increase the amount of stem cells in human blood at rest and after exercise. The ingredients found in NutraStem® can be found in nutrition or vitamin shops/stores.

Read the detailed description

A randomized double blinded placebo controlled trial of a nutraceutical preparation. Up to 60 men and women between the ages of 50 and 70, and generally healthy will participate in this study. . Up to 30 participants will receive the nutritional supplement and up to 30 will receive placebo.

Potential participants will be screened by telephone and have the study explained to them in detail. If they qualify and choose to participate they will come in for the first of three visits. Informed consent will be obtained and demographic information collected. Information requested on the demographic form includes ethnicity, income, education, marital status, smoking and alcohol use, and exercise habits. Next they will have blood pressure checked and if not within parameters they will be dropped from the study and informed that they need to follow up the abnormal result with their health care provider. Those that pass these screening tests will have 15 to 25 cc's of peripheral blood (serum) collected by the study coordinator via venipuncture while at rest. They will then stretch for 2 minutes (60 seconds marching in place followed by 10 toe touches) followed by accelerating treadmill walking exercise. The exercise intervention will consist of a 15 minute period of walking on a treadmill. The treadmill will not be inclined during the intervention. The participants target heart rate will be determined by deducting their age from 220. They will start walking on the treadmill at a speed of 1.7 mph and the speed will be titrated as indicated to keep their heart rate at 50 to 90% of target. Heart rate will be monitored via the pulse oximetry feature of the Welch Allyn vital signs monitor. Blood pressure will be measured every 3 minutes during the exercise intervention and until they have returned to baseline (within 10 points) following cessation of the exercise protocol. The test will be stopped for any participant complaint of chest pain, excess fatigue, difficulty breathing, a blood pressure reading of more than 180/94, or a participant request. If symptoms increase or do not completely resolve with 15 minutes of rest the study coordinator will call 911 (through campus police) to activate the EMS response. If symptoms resolve completely within 15 minutes participants will be withdrawn from the study and advised to follow up with their health care provider. Any participant unable to complete the exercise intervention for any reason will be withdrawn from the study.

Five to fifteen minutes after the exercise intervention has been completed blood will again be collected in exactly the same manner as the resting sample. Participants will then receive a 2 week supply of either NutraStem or placebo and will be advised to take one tablet every morning and evening before meals for the next 2 weeks. If the participant is unable to complete any portion of the visit activities at any visit they will be withdrawn from the study due to their inability to complete the study. All visit activities will be recorded in detail on the visit session record.

The second visit will occur 2 weeks later and include a blood pressure check, an at rest blood draw, the exercise intervention, and then a repeat blood draw five to fifteen minutes after completion of the intervention. Participants will then receive a 2 week supply of either NutraStem or placebo and will be advised to take one tablet every morning and evening before meals for the next 2 weeks. I Participants will be advised to bring their empty pill containers to their next session so we can confirm they are taking the supplement as required. If the blood pressure is outside of the specified range they will be dropped from the study and no blood collection or study intervention will take place.

The third visit will be the same as the second visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NutraStemDrug

    Also called NT-020

    Determine whether NutraStem® in combination with an exercise stimulus will cause increased human peripheral blood sample levels of CD34+ and CD133+ adult stem cells and whether these stem cells display more protection against oxidative stress.

  • PlaceboDrug

    Also called Sugar pill

    Determine whether NutraStem® in combination with an exercise stimulus will cause increased human peripheral blood sample levels of CD34+ and CD133+ adult stem cells and whether these stem cells display more protection against oxidative stress.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NutraStem in people with Adult Stem Cell Proliferation, run by University of North Texas Health Science Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of CD133+ Cells (time frame: Baseline, 2 weeks, 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2019.
