About this study

Official title: Role of GLP-1 in Congenital Hyperinsulinism:Effect of Exendin-(9-39) on Fasting Adaptation and Protein Sensitivity

The purpose of this study is to examine the effects of exendin-(9-39) on fasting blood glucose and protein induced hypoglycemia on subjects with Congenital Hyperinsulinism. Funding Source - FDA Office of Orphan Products Development (OODP).

Read the detailed description

This is a placebo controlled study with randomized crossover design to evaluate the effect of the glucagon-like peptide-1 (GLP-1) receptor antagonist, exendin-(9-39), on fasting blood glucose levels, protein-induced hypoglycemia, and fasting tolerance of subjects with congenital hyperinsulinism due to mutations in the ATP- sensitive potassium channel (KATP) channel.

Being tested
Exendin-(9-39), placebo
Keywords
Hyperinsulinism, Hypoglycemia, KATP channel

Study groupRoleWhat they receive
Vehicle first, then Exendin-(9-39)OtherAn infusion of vehicle (0.9%NaCl) will run for 60 minutes(time -60 to 0) before starting the study infusion of vehicle or exendin-(9-39). At time 0, vehicle (0.9%NaCl) will be started and will continue for 6 hours. The following day, at time 0, exendin-(9-39) at a dose ranging from 100-500pmol/kg/min will be started and continue for 6 hours. During both infusions, blood glucose, insulin, c-peptide, GLP-1, and glucagon will be measured every 30 minutes.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Exendin-(9-39) in people with Congenital Hyperinsulinism, run by Diva De Leon 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 4 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 13 Mar 2020. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 18 Jan 2018). 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?

Area Under the Curve (AUC) Plasma Glucose (time frame: Time 0 min - time 360 min). 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 NCT00897676, which also lists 1 linked publication.

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 13 Mar 2020.
