Active Clinical Trials

Help our researchers make discoveries in nutrition and wellness science by participating in a clinical trial.

Clinical trials offer our researchers the opportunity to study the effects of nutrition and behavioral interventions on real people. Participation in a clinical trial helps our scientists move their research forward, and it may also have positive effects on your own health and wellness journey. Eligibility for clinical trials depends on many factors; if you're interested in participating, please read the individual trial information to determine whether you are eligible for the study.

Exercise and Donor Immune Cell Xenotransplantation

EXERCISE AND DONOR IMMUNE CELL XENOTRANSPLANTATION


We are recruiting healthy, non-smoking individuals between the ages of 21-44 to participate in a study investigating the relationship between exercise and the immune system. This study aims to understand how exercise changes immune cell numbers within the blood and whether or not these changes can positively impact outcomes if used in a cancer transplant setting. Participants must not have cardiovascular disease, asthma, or be taking medications that affect immune function (i.e. ibuprofen/aspirin, anti-histamines).

The first part of this study will require participants to complete cycling exercise trials on two separate occasions. The second part of this study involves five additional exercise bouts where participants will be given either a placebo or a beta blocker drug. The total time commitment for part one is ~4 hours; the total time commitment for part two is ~20 hours. Upon completion of the study, participants will receive compensation of $50 if they complete part one and $150 if they complete part two.

If interested, please email Dr. Richard Simpson at rjsimpson@arizona.edu.

This study is being conducted by Dr. Richard Simpson, School of Nutritional Sciences and Wellness at the University of Arizona and has been approved by the Institutional Review Board (IRB) of the University of Arizona.

EXERCISE AND TOTAL VIRAL IMMUNITY


We are recruiting healthy, non-smoking individuals between the ages of 18-44 to participate in a study investigating the relationship between exercise and the immune system. This study aims to assess the effectiveness of exercise to beneficially alter immunity against SARS-CoV-2 and many other common respiratory viruses. Participants must not have cardiovascular disease, asthma, or be taking medications that affect immune function (i.e. ibuprofen/aspirin, anti-histamines).

Participants will be required to engage in three to five exercise sessions and provide blood samples. The total time commitment will be between 4-12 hours, and participants will receive compensation up to $150; total time commitment and compensation are dependent upon the number of exercise trials completed.

If interested, please email Dr. Richard Simpson at rjsimpson@arizona.edu.

GRAPE POWDER STUDY


We are seeking participants 30 - 65 years of age with a BMI of 25-36 kg/m2. Participants must be healthy and not taking medications for high cholesterol, blood pressure, diabetes, or inflammatory conditions.

Participants will be provided with freeze-dried grape powder and a placebo powder for 6 - 8 weeks each, with a 4-week break between test periods (total time for study is 16-20 weeks).  At the completion of the study, participants will receive lab results and compensation of $350.

If you are interested in learning more about the study, please call 520-621-5382 or email FBHlab@email.arizona.edu, mention the Grape Study, and leave your name and a contact number.

This study is being conducted by Dr. Ann Skulas-Ray, School of Nutritional Sciences and Wellness at the University of Arizona and has been approved by the Institutional Review Board (IRB) of the University of Arizona.

SALIVARY GLAND WOUND HEALING AFTER RADIOTHERAPHY


This is a research study investigating radiation treatment-induced salivary gland damage. Eligibility includes adults undergoing standard of care surgery for cancer in the head and neck region. Salivary gland tissue that is being removed as part of the standard surgical treatment, and which would otherwise be discarded, will be collected and studied in the laboratory.

The purpose of this research study is to understand how radiation treatment causes damage to salivary glands and to learn how we might prevent such damage. No foreseeable risks or discomfort is anticipated from the research, since the tissue will be collected after it is removed as part of a normally scheduled surgery.

If interested, please email Dr. Kirsten Limesand at limesank@arizona.edu.

This study is being conducted by Dr. Kirsten Limesand, School of Nutritional Sciences and Wellness at the University of Arizona and has been approved by the Institutional Review Board (IRB) of the University of Arizona.
