About this study

Official title: Beta-cell Evaluation Through Data-driven Assessments (BETA): Study in Prediabetes Type 2 Diabetes

This study is testing the feasibility of using non-invasive, remote digital tools including continuous glucose monitors (CGMs) and the Oura Ring to predict the function of beta-cells, the cells in the pancreas that secrete insulin. This study is being done in individuals with prediabetes or Type 2 diabetes. The aim is to develop remote digital tools that can predict the health and functioning of the pancreas in people with prediabetes or Type 2 diabetes, allowing personalized treatment approaches to preserve insulin secretion.

Read the detailed description

The objective of this research is to construct a real-time, non-invasive predictor of pancreatic beta-cell function for individuals with T2D or prediabetes, using data from a CGM alongside a diverse array of health, lifestyle, and behavioral metrics gathered via a smartphone app and Oura Ring. Investigators will study individuals with T2D or prediabetes using remote digital tools to determine the risk of conversion from prediabetes to T2D as it relates to beta-cell function, as well as personalized treatment options for individuals with Type 2 diabetes. Participants will undergo detailed evaluations of pancreatic beta-cell function at the Buck Institute's Clinical Research Unit (CRU) using the Minimal Model Oral Glucose Tolerance Test (OGTT) with analysis of C-peptide, glucose and insulin levels, and a Meal Tolerance Test (MTT) at the end of the study. Participants will complete 4 at-home real-world challenges that will also involved MTTs with or without a controlled psychological stress test that will be administered to you by research staff. From this data, the investigators can calculate clinical measures of beta-cell function, including oral Disposition Index as well as the Homeostatic Model Assessment of beta-cell function (HOMA-B), and beta-cell glucose sensitivity. This hybrid approach, blending advanced digital data acquisition with traditional clinical assessments, will facilitate the identification of critical data patterns and biomarkers correlating with beta-cell function. The envisioned outcome is a scalable tool for early identification of individuals experiencing a decline in beta-cell function.

What is being measured

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

  1. Feasibility: Retention

    Proportion of participants retained according to study protocol

    Measured: 6-8 months

  2. Feasibility: Adherence

    Mean adherence to completing in-app daily study measures

    Measured: 6-8 months

Secondary outcomes (1)
  1. Continuous Glucose Excursions

    Participants glucose excursions will be collected from personal CGMs. A glucose excursion is defined as a change (+/- 25mg/dl) since the last CGM reading. Associations between glucose excursions and factors relating to diet, stress, sleep and activity will be estimated.

    Measured: 6-8 months

Timeline

Individual data sharing
Yes: Deidentified study data will be shared beyond the internal research team by 4YouandMe with external qualified researchers using an ARPA-H approved data sharing platforms such as the Synapse Data Sharing Platform at Sage Bionetworks. This data sharing will occur 1 year after the last participant has exited the study. Researchers from other institutions, and other third parties will be able to apply for access to the deidentified dataset by presenting a research study plan for analysis that has been reviewed by an IRB or ethics committee. Data released through these ARPA-H approved data sharing platforms will be stored indefinitely.

Questions about this trial

What is this clinical trial studying?

An observational study of Prediabetes and Type 2 Diabetes, run by 4YouandMe 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 12 inclusion and 13 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: enrolling by invitation, as of the sponsor's last update on 20 May 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?

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?

Feasibility: Retention (time frame: 6-8 months). 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 20 May 2026.
