About this study

The study investigations include evaluation of the acute effects of a single dose of dapagliflozin (10mg), exenatide (5µg), a combination of exenatide and dapagliflozin or placebo under insulinopenic condition and the long term effect under basal conditions before and after 12 weeks treatment with dapagliflozin, Exenatide extended release, a combination of Exenatide extended release and dapagliflozin or placebo on ketogenesis, glucagon and lipolysis.

Read the detailed description

The study investigations include evaluation of the acute effects of a single dose of dapagliflozin (10mg), exenatide (5µg), a combination of exenatide and dapagliflozin or placebo under insulinopenic condition and the long term effect under basal conditions before and after 12 weeks treatment with dapagliflozin, Exenatide extended release, a combination of Exenatide extended release and dapagliflozin or placebo on ketogenesis, glucagon and lipolysis.

In the acute effects study, qualified patients will come fasting to the research center. Review of study procedures and vitals will be performed. Insulin infusion (pump) will be stopped and basal blood, urine and adipose tissue biopsy samples will be obtained. Placebos, exenatide (5µg) or dapagliflozin (10mg) (with appropriate placebos) or combination of exenatide and dapagliflozin will be administered, according to a randomized fashion, and blood samples will be collected every 30 min for up to 8 hours after starting the treatment. Urine will be collected every hour up to 8 hours and a second adipose tissue biopsy will be collected at 6 hours after the start of the treatment. Additional blood samples will be collected at 1, 2, 4 and 6 and 8 hour marks for MNC isolation. Plasma and mononuclear cell (MNC) fractions will be prepared from the blood samples. The patient will then come back at the 24 hour mark for a fasting blood and urine collection. The long term study will then commence. Exenatide extended release or dapagliflozin (along with appropriate placebos) or a combination of both drugs will be started and continued for 12 weeks according to original randomization of day 0. In the long term study, dapagliflozin (or the appropriate placebo) will be started at 5mg dose and will be titrated to 10mg/day after 5 days. Fasting blood and 24hr urine samples will be collected at 1, 4 and 8 weeks. At 12 weeks, the 2nd acute effects testing study will be repeated as described above.

Measurements of beta-hydroxybutyrate, acetoacetic acid, glucose, FFA and glucagon, will be measured from all blood samples collected. HSL, GLP-1, glycerol, electrolytes, serum bicarbonate, cortisol and catecholamines will be measured at 0, 60, 120, 240, 360, 480 min and at 24hr following single dose studies at 0 and 12 weeks visits and at baseline on the 1, 4 and 8 weeks visits. Ketone bodies will be measured in all urine samples. All MNC and adipose tissue samples will be tested for HSL and SGLT2 expression.

What is being measured

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

  1. Change in Beta-hydroxybutyrate Levels in Blood

    Beta-hydroxybutyrate (BHB) was measured in blood during the acute stress conditions in all the groups after single dose intervention at baseline (0 Week) and at 12 weeks of treatment. The magnitude of change at each of these visits was calculated from each visit baseline (0 hr) and the difference between the change at 12 weeks was compared to the change at 0 week and reported as: Change at week 12 - change at week 0.

    Measured: 12 weeks

Secondary outcomes (4)
  1. Change in HbA1c Following Treatment

    Hemoglobin A1c (HbA1c) was measured in basal conditions in all the groups at week 0 and week 12 of treatment. The change in HbA1c from baseline at 12 weeks is calculated as: HbA1c at week 12 - HbA1c at week 0.

    Measured: 12 weeks

  2. Change in Urinary Beta-hydroxybutyrate (BHB) After 12 Weeks of Treatment

    Beta-hydroxybutyrate (BHB) was measured in urine during the acute stress conditions in all the groups after single dose intervention at baseline (0 Week) and at 12 weeks of treatment. The magnitude of change at each of these visits was calculated from each visit baseline (0 hr) and the difference between the change at 12 weeks was compared to the change at 0 week and reported as: Change at week 12 - change at week 0.

    Measured: 12 weeks

  3. Change in Plasma Glucagon

    change in basal plasma glucagon after 12 weeks of dapagliflozin and Bydureon or combination of both treatments compared to baseline

    Measured: 12 weeks

  4. Change in Total Insulin Dose

    change in total (basal or long acting and short acting) insulin daily dose calculated as daily units/Kg body weight at 12 weeks from baseline (0 week). Long acting or basal insulin dose (in units of insulin) plus short acting (meal) insulin doses administered through the day and reported by patients in patients logs or from insulin pumps are added and divided by body weight in Kg. The reported total insulin dose/Kg represents the average of last 3-7 days before the visit.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Exenatide/Exenatide extended release and Dapagliflozin in people with Evaluate Ketogenic Stress, run by University at Buffalo 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 35 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 29 Feb 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Feb 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?

Change in Beta-hydroxybutyrate Levels in Blood (time frame: 12 weeks). 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 29 Feb 2024.
