About this study

Official title: A Randomized, Placebo-controlled, Double-blinded Cross-over Study of the Pharmacologic Action of a GPR119 Agonist on Glucagon Counter-regulation During Insulin-induced Hypoglycemia in Type 1 Diabetes Mellitus

The purpose of this study is to test if a specific research medication could increase the response to low blood glucose in people with type 1 diabetes. The response of the body to low blood sugar will be measured in healthy people as a reference point.

Read the detailed description

This is a placebo-controlled, double-blinded, within-subject, cross-over phase 2a study. In randomized order, (Latin square, randomly assigned to placebo-active and active-placebo periods) and in a double-blinded manner, the participants with T1D received 14 days of daily dosing with MBX-2982 (or placebo), taken at the same time each day after breakfast. The last dose of treatment/placebo was given when the glucose tracer infusion for the euglycemic/hypoglycemic-glucose clamp started. Participants with T1D underwent two euglycemic-hypoglycemic clamps (induction of controlled hypoglycemia by an insulin infusion), using a within-subject cross-over design, with the two clamps separated by approximately four weeks, that is, two weeks of drug washout followed by two weeks of treatment with the alternative therapy. Glucagon, hepatic glucose production and other counter-regulatory hormonal responses were assessed during hypoglycemia. After completion of the first clamp study, participants did not receive any study medication for two weeks (washout phase) and then begin 14 days of the other arm (placebo or MBX-2982) in a double-blinded manner, followed by a repeat euglycemic-hypoglycemic clamp study. During treatment on each arm and during wash out phase, a blinded CGM was used to assess daily and nocturnal patterns of glycemia. On the day preceding a clamp study, while admitted to the research unit, a standardized meal test was used to assess fasting and postprandial glucagon, GLP-1 and GIP secretion. A healthy normal volunteer cohort with no diabetes was enrolled in the study for 14 days for comparison of normal responses to insulin induced hypoglycemia.

What is being measured

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

  1. Maximal Glucagon Concentration During Hypoglycemia

    Maximal glucagon concentration during insulin induced hypoglycemia. This was measured during the hypoglycemic steady state of the hyper-insulinemic euglycemic-hypoglycemic clamp study.

    Measured: Day 14, Day 42

  2. Total Area Under the Curve (AUC) for Glucagon During Hypoglycemia.

    This outcome was measured during the hypoglycemic steady state of the hyper-insulinemic euglycemic hypoglycemic clamp study. Total area under the curve (AUC) for glucagon was measured during the time points of 120 minutes to 140 minutes of the clamp.

    Measured: Day 14, Day 42

  3. Incremental AUC for Glucagon During Hypoglycemia (Above Baseline Levels During Euglycemia)

    This is the difference between the AUC during the hypoglycemic steady state (time points 120 - 140 mins of clamp) and the baseline glucagon levels during euglycemic steady state (timepoints 60 min - 80 mins of the clamp)

    Measured: Day 14, Day 42

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Study Medication (MBX-2982) and No medication for this group in people with Diabetes Mellitus, Type 1, run by AdventHealth Translational Research Institute 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 13 inclusion and 42 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: finished, as of the sponsor's last update on 17 Oct 2024. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximal Glucagon Concentration During Hypoglycemia (time frame: Day 14, Day 42). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04432090, which also lists 18 linked publications.

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 17 Oct 2024.
