About this study

Official title: Effects of Dorzagliatin on 1st Phase Insulin and Beta-cell Glucose Sensitivity in Individuals With Impaired and Normal Glucose Tolerance

Dorzagliatin, a novel dual allosteric activator of glucokinase. reduces blood glucose by increasing insulin secretion by enhancing sensitivity of beta cells to glucose. In this placebo controlled cross over study, we examined the effects of dorzagliatin in people with impaired glucose tolerance and normal glucose tolerance.

Read the detailed description

Objective

To investigate the acute effects of a single dose dorzagliatin on first phase insulin secretion and beta cell glucose sensitivity (βCGS) in individuals with impaired and normal glucose tolerance

Methodology and rationale:

A total of 20 subjects will be recruited, 10 in impaired glucose tolerant (IGT) and 10 in normal glucose tolerant (NGT) groups, respectively. Eligible participants will have a two-hour hyperglycemic clamp following a single dose of dorzagliatin or placebo in a randomized crossover fashion on V2 or V3. Subjects will be randomized to dorzagliatin 50mg or placebo in the IGT and NGT groups. Arterialized blood glucose (venous blood drawn from back of the hand placed in a temperature regulated box), measured every 5 minutes at the bedside Yellow Spring Instrument (YSI) or EKF glucose analyser, will be maintained at 12 mmol/l using an infusion of dextrose. Blood will be sampled for insulin and C-peptide at regular intervals for evaluation of first and second phase insulin secretion. Glucagon-like peptide-1 (GLP-1) and glucagon will be evaluated at regular intervals during the clamp studies. After 14 ± 2 days washout out (Day 14), participants will receive a single dose of dorzagliatin or matched placebo followed by a repeat hyperglycemic clamp to evaluate differences in beta-cell function.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Dorzagliatin in people with Glucose Intolerance, run by Chinese University of Hong Kong.

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 11 inclusion and 18 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 25 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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?

2-hour hyperglycemic clamp (time frame: 2-hour). 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 25 Jul 2022.
