Trial to Confirm the Efficacy and Safety of Dasiglucagon in the Treatment of Hypoglycemia in T1DM Children

Phase 3, Randomized, Double-blind, Placebo/Active-controlled, Parallel-arm Trial to Assess Efficacy, Safety, and Pharmacokinetics of Dasiglucagon Relative to Placebo/GlucaGen® as Rescue Therapy for Severe Hypoglycemia in Children With T1DM Treated With Insulin

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

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.

Inclusion Criteria:

1. Following receipt of verbal and written information about the trial, patient, parent(s) or guardian(s) of the patient must provide signed informed consent before any trial-related activity is carried out

2. Female or male patients with T1DM for at least 1 year, diagnostic criteria as defined by the American Diabetes Association; and receiving daily insulin

3. At least 6.0 years of age (inclusive) and less than 18.0 years

4. Body weight ≥20 kg

5. Female patients must meet one of the following criteria:

   a. Participant is of childbearing potential and agrees to use one of the accepted contraceptive regimens throughout the entire duration of the trial from screening until last follow-up visit. An acceptable method of contraception includes at least one of the following: i. Abstinence from heterosexual intercourse ii. Systemic contraceptives (birth control pills, injectable/implant/ insertable hormonal birth control products, transdermal patch); if the participant is using systemic contraceptives, she must use an additional form of acceptable contraception (iii or iv, below) iii. Intrauterine device (with and without hormones) iv. Condom with spermicide or b. Participant is of non-childbearing potential due to pre-puberty status or a medical condition confirmed by the investigator

6. Male patients must meet the following criteria: If sexually active, uses condom and partner practices contraception during the trial from screening and until last follow-up visit

7. Willingness to adhere to the protocol requirements
