A Trial to Evaluate the Immunogenicity of Dasiglucagon and GlucaGen in Patients With Type 1 Diabetes Mellitus

Patients with T1DM were randomly assigned in a 1:1 ratio to receive 3 SC injections of either dasiglucagon (0.6 mg) or GlucaGen (1 mg), with 1 week between doses. Patients were followed for 15 weeks from the day of the first dose to assess the immune response. Patients with previous exogenic glucagon exposure were not excluded from the trial, but the information on previous glucagon administration was recorded to enable subgroup analyses. It was expected that 112 patients in total would be randomly assigned to treatment groups and treated. A total of 90 patients were expected to complete the trial (45 in each treatment arm). To qualify as completed, the patient had to be dosed according to the procedure described in the protocol and to have blood drawn for the antidrug antibody analyses as scheduled.
