About this study

Official title: A Single-center, Randomized, Double-blind, Placebo-controlled, Parallel Study to Investigate the Ability of Beta-glucan (to Augment Immune Function, Decrease URTI Incidence Rates, and Counter Immune Changes in Marathon Runners

This proposed study is designed to assess the efficacy of a capsule containing beta-glucan taken orally daily as compared to a placebo capsule on the URTI symptoms, and the immune response change in marathon runners

Read the detailed description

At screening, an informed consent form will be given to the potential volunteer. They will be required to read the information and will be given the opportunity to seek more information if needed or provided with the option of taking the consent form home to review prior to making their decision. If agreeable, the volunteer will sign the consent form and receive a duplicate of the signed copy. Once consent has been obtained, the screening visit will proceed. Each volunteer will be sequentially assigned a screening number to be entered in the screening and enrollment log. Screening assessments include: review medical history, assess inclusion and exclusion criteria, vitals, study diary, URTI symptom questionnaire, bowel diary, and GI symptom questionnaire.

The next visit will be scheduled 14 days prior to their marathon date (baseline). Participants will be reminded to complete URTI questionnaire, daily study diary, modified GI symptoms and bowel diary in advance of this baseline visit. At baseline participants will begin daily completion of study diaries, URTI questionnaires, daily bowel diaries, and GI tolerance questionnaires. In clinic subjects will complete mood and stress questionnaires, and blood sample for the analysis of CRP and NK cell activity. In addition, on the day of the marathon the participant will be instructed to complete a muscle soreness assessment.

Two and four weeks post-marathon participants will return to the clinic for with unused investigational product, completed study diaries, daily URTI questionnaires, daily bowel diaries, and GI tolerance questionnaires. In clinic subjects will complete mood and stress questionnaires, and blood sample for the analysis of CRP and NK cell activity.

  2. Severity of cold/flu symptoms from Wisconsin Upper Respiratory Symptom Survey

    Total severity score (each symptom scored on scale of 0-no symptom to 7-severe symptom)

    Measured: ANOVA with 2 and 4 weeks post-marathon

  3. URTI Episodes from Wisconsin Upper Respiratory Symptom Survey

    Total number of URTI Episodes/person

    Measured: ANOVA with 2 and 4 weeks post-marathon

  4. Sick days

    Total number of sick days/person

    Measured: ANOVA with 2 and 4 weeks post-marathon

  5. Sick days

    Percentage of subjects with sick days

    Measured: ANOVA with 2 and 4 weeks post-marathon

  6. Stress Level from the perceived stress scale

    Change from baseline on the Perceived Stress Scale

    Measured: ANOVA with 2 and 4 weeks post-marathon

  7. C-Reactive Protein

    Change in concentration from baseline

    Measured: ANOVA with 2 and 4 weeks post-marathon

  8. Natural Killer Cell Activity

    Change from baseline

    Measured: ANOVA with 2 and 4 weeks post-marathon

  9. Gastrointestinal symptoms

    Total gastrointestinal symptom rating score (GSRS)

    Measured: ANOVA with 2 and 4 weeks post-marathon

Questions about this trial

What is this clinical trial studying?

A study testing Beta-Glucan in people with Cold and Cold Symptom, run by Kemin Foods LC at 1 site in Canada.

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 8 inclusion and 14 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 3 Feb 2021. 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 Canada. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Global Cold/Flu Symptom Severity Score Wisconsin Upper Respiratory Symptom Survey (WURSS) (time frame: ANOVA with 2 and 4 weeks post-marathon). 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 3 Feb 2021.
