About this study

Official title: Pilot Study to Evaluate Substances in Sweat, Saliva, and Blood

This trial collects and analyzes sweat and saliva samples compared to blood in detecting chemical concentrations in the body in patients with chronic or infectious diseases receiving medications. Wearable sweat sensors are capable of monitoring electrolytes and metabolites (sodium, potassium, glucose, lactate, etc.) for health monitoring and disease diagnosis. Designing wearable sweat sensors capable of providing information regarding drug administration may be challenging due to ultralow concentrations in biofluids. This trial seeks to determine if the use of a smart wristband can accurately measure the levels of chemicals and substances in sweat.

PRIMARY OBJECTIVE:

  1. To compare novel, home-based methods of quantitating medication concentrations in either saliva or sweat to the 'gold standard' of liquid chromatography - mass spectrometry of plasma.

SECONDARY OBJECTIVES:

  1. To compare novel home-based methods of quantitating substances in either saliva or sweat to the 'gold standard' in plasma.

II. Assess the ease of obtaining home-based samples.

OUTLINE:

Patients undergo collection of sweat samples via Macroduct Sweat Collection System 3710S and saliva and blood samples within 24 hours after medication administrations. Patients also complete questionnaires over 5-10 minutes and have medical charts reviewed.

After completion of study, patients are followed up periodically.

Being tested
Biospecimen Collection, Medical Chart Review, Questionnaire Administration
Medical subject headings
Chronic Disease, Communicable Diseases

Receives: Procedure: Biospecimen Collection; Other: Medical Chart Review; Other: Questionnaire Administration

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Predictive performance of the home-based sampling

    Will be assessed by Pearson correlation and quantification of the predictive performance. The predictive performance of the home-based sampling methods will be assessed by calculating the median percentage prediction error (MPPE).

    Measured: Up to 4 hours

  2. Observed plasma concentrations

    Will be assessed by Pearson correlation and quantification of the predictive performance. The values from plasma will be considered the observed concentration.

    Measured: Up to 4 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Disease and Infectious Disorder, run by City of Hope Medical 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 4 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 22 Oct 2026. 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. 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive performance of the home-based sampling (time frame: Up to 4 hours). 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 22 Oct 2026.
