Clinical Trial 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.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
