Clinical Trial Summary

A phase 3, randomized, double-blind, placebo- and active-controlled, parallel-arm trial to assess the efficacy, safety, and pharmacokinetics of dasiglucagon relative to placebo and GlucaGen® when administered as a rescue therapy for severe hypoglycemia in children with type 1 diabetes mellitus (T1DM) treated with insulin

Description:

At least 40 children ≥6 years and <18 years of age with T1DM were planned to be randomized into the trial (2:1:1 for dasiglucagon:placebo:GlucaGen) and stratified by age intervals: 6 years to <12 years, and 12 years to <18 years; and by injection site (abdomen or thigh). A minimum of 16 patients were enrolled into each age group, including a minimum of 8 patients in each age group in the dasiglucagon treatment arm. In Germany only, a staggered approach was applied, whereby a positive safety assessment needed to be available for at least 10 patients in the age group of 12 years to <18 years who had completed the dosing visit in the overall trial before younger patients (6 to 11 years of age) were allowed to be enrolled.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Plasma Glucose Recovery	Plasma glucose recovery was defined as first increase in plasma glucose of =20 mg/dL (1.1 mmol/L) from baseline during the hypoglycemic clamp procedure without administration of rescue intravenous (IV) glucose. Patients who received rescue IV glucose before 45 minutes and patients not recovering within 45 minutes after dosing were censored at 45 minutes. Time to plasma glucose recovery was summarized for each treatment group using Kaplan Meier (KM) estimates together with the 95% confidence interval.; Note that the upper confidence limit for the placebo median was not estimable, but is set to 45 minutes (censored value) here.	0-45 minutes after dosing
Secondary	Plasma Glucose Recovery	Plasma glucose recovery within 30 minutes, within 20 minutes, within 15 minutes, and within 10 minutes after study drug injection without administration of rescue intravenous (IV) glucose. Plasma glucose recovery was defined as the first increase in plasma glucose of =20 mg/dL (1.1 mmol/L) from baseline without administration of rescue intravenous glucose.	0-30 minutes after dosing: assessed at 10, 15, 20 and 30 minutes after study drug injection
