Clinical Trial Summary

The aim of the study is to compare the efficacy of low-dose dasiglucagon (Zealand Pharma, Denmark) to oral carbohydrate consumption for prevention of s.c. insulin-induced hypoglycemia in CSII- and MDI-treated people with type 1 diabetes.

Description:

Near-normalization of blood glucose levels through intensive insulin therapy has shown to reduce the risk of diabetes late complications, but the approach is associated with two major side effects: hypoglycemia and weight gain. Although management of hypoglycemia through oral carbohydrate consumption is generally effective, the approach can lead to excessive carbohydrate intake and cause rebound hyperglycemia. It has previously been demonstrated that subcutaneous (s.c.) low-dose glucagon can be utilized to effectively treat mild hypoglycemia in people with type 1 diabetes. However, the instability in aqueous solution of currently available glucagon and the need for reconstitution with sterile water immediately prior to administration has limited its clinical role outside emergency settings. Due to the stability and ready-to-use formulation, dasiglucagon does not hold the limitations known for the currently available glucagon preparations.

The aim of this randomized, partially single-blinded, three-arm cross-over study is to compare the efficacy of low-dose dasiglucagon (80 and 120 μg) to oral carbohydrate (15 g) consumption for prevention of s.c. insulin-induced hypoglycemia in CSII- and MDI-treated people with type 1 diabetes. On each study visit (separated by ≥ 3 days), an initial insulin bolus will be administered (at t = 0) aiming for a plasma glucose (PG) level of 3.0 mmol/l. When reaching 4.5 mmol/l, the intervention (s.c. dasiglucagon or oral carbohydrates) will be administered (t-intervention = 0), whereafter PG will me monitored for an additional 180 min.
