About this study

Official title: Subcutaneous Dasiglucagon Use During Exercise In People With Type 1 Diabetes: Effects On Plasma Glucose And Exercise Metabolism

This proof-of-principle study to assess effects of different doses (mini and micro) of subcutaneous glucagon analog Dasiglucagon (Zealand Pharma, Copenhagen, Denmark) on the change in blood glucose concentration during moderate-intensity exercise in people with T1D.

Read the detailed description

People with type 1 diabetes (T1D) are recommended to engage in regular exercise for a variety of health and fitness reasons. However, moderate-intensity exercise is associated with an increased risk of hypoglycaemia in people with T1D. Current guidelines are to reduce insulin dose and/or increase carbohydrate consumption in the context of the exercise bout. However, despite the many advances in insulin formulations and delivery devices, hypoglycaemia remains a significant risk. Mini-dose glucagon taken before an exercise bout has been shown to be an effective non-caloric strategy to prevent exercise-induced hypoglycaemia. However, even the reduced doses (150-200 µg) used in previous studies might still be rather high translating into potential side-effects (i.e. hyperglycaemia, gastrointestinal symptoms, etc.). Lower doses (below 100 µg, micro-glucagon) may be sufficiently effective to counteract hypoglycaemia risk associated with exercise and associated with better tolerance. Moreover, there is little information on the effects of subcutaneous glucagon on glycogen stores and changes in exercise metabolism. Greater understanding of exercise-associated metabolism following mini- and micro-dose glucagon using techniques such as magnetic resonance spectroscopy (MRS), continuous glucose monitoring (CGM), stable isotope tracers, and indirect calorimetry may result in novel approaches to improve blood glucose management in people with T1D. Utilising these techniques may also further our understanding of the optimal glucagon dosing (timing and amount) during exercise to manage hypoglycaemia and reduce the risk of adverse events. Proof-of-principle study to assess effects of different doses (mini and micro) of subcutaneous glucagon analog Dasiglucagon (Zealand Pharma, Copenhagen, Denmark) on the change in blood glucose concentration during moderate-intensity exercise in people with T1D. Secondly, to investigate exercise-metabolism following Dasiglucagon injection using 3 tesla magnetic resonance spectroscopy (MRS) and indirect calorimetry. Third, to assess participant experience of Dasiglucagon during exercise and the incidence of adverse events.

What is being measured

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

  1. Time to hypoglycaemia

    Time (in minutes) to hypoglycaemia (plasma glucose <3.9mmol/l) during 60 minutes of aerobic exercise in individuals with type 1 diabetes using mini and micro doses of Dasiglucagon compared to no Dasiglucagon

    Measured: 60 minutes

Secondary outcomes (8)
  1. Change in glycaemia during exercise

    Change in blood glucose concentration, calculated based on the participants' glucose at the start of exercise and the last value measured at the end of exercise. If the exercise is stopped early because of hypoglycaemia, the last exercise glucose value will be used for analysis

    Measured: 60 minutes

  2. Glucose during exercise

    Mean glucose concentration and area under the glucose curve during exercise

    Measured: 60 minutes

  3. Glucagon during exercise

    Mean glucagon concentration and area under the glucagon curve during exercise

    Measured: 60 minutes

  4. Time in target

    Time in target glycaemic range (4-10 mmol/L) in the recovery period and overnight

    Measured: 24 hours

  5. Time in target during exercise

    Time in target glycaemic range (4-10 mmol/L) during exercise

    Measured: 60 minutes

  6. Hypoglycaemia

    Incidence of hypoglycaemia (≤3.9 mmol/L for 15 min or more) during the 24 hour post exercise recovery period

    Measured: 24 hours

  7. Glycogen content

    Change in skeletal muscle and hepatic glycogen following exercise

    Measured: 4 hours

  8. Any adverse events

    Adverse symptoms following glucagon/placebo use

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Micro-glucagon and Mini-glucagon in people with Type 1 Diabetes and Hypoglycemia, run by Insel Gruppe AG, University Hospital Bern.

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 6 inclusion and 5 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: withdrawn, as of the sponsor's last update on 1 Sep 2023. 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. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Time to hypoglycaemia (time frame: 60 minutes). 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 1 Sep 2023.
