About this study
Official title: Transdermal Optical Imaging (TOI) as a Non-invasive Measure to Detect Changes in Hydration Status in Healthy Adults and Athletes: Phase 3b Multi-center Trial for Model Development
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hydration status, including: 1) at various timepoints throughout a 24-hour period in healthy adults from the general population (GENPOP), and 2) before and after a team coach-led training session in athletes competing in a sport (ATHLETE). TOI data will be collected alongside standard reference measures of hydration status.
In this study each subject will serve as their own control.

The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hydration status, including: 1) at various timepoints throughout a 24-hour period in healthy adults from the general population (GENPOP), and 2) before and after a team coach-led training session in athletes competing in a sport (ATHLETE). TOI data will be collected alongside standard reference measures of hydration status.
In this study each subject will serve as their own control.

Questions about this trial
What is this clinical trial studying?
A study testing GENPOP ad libitum fluid intake, GENPOP fluid restriction and ATHLETE ad libitum fluid intake in people with Dehydration, run by PepsiCo Global R&D at 4 sites 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 20 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 19 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Matthew Hinkley, PhD (914-742-4975, Matt.Hinkley@pepsico.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Transdermal Optical Imaging (TOI) signals (time frame: Four time points for GENPOP over 24 hours (Day 1 ~8 a.m., ~11:30 a.m., ~3:30 p.m., Day 2 ~8.a.m.; for ATHLETES, on arrival before a single ~45 minute exercise training session and immediately following a 30 minute cool down period post-exercise). The study lists 5 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 19 Jan 2024.
