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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
