Recruitment
|
||||||||||||||||||||||||||||
Recruitment details |
The patients were recruited from 7 trial centers in Austria (1 center), Canada (3 centers), Germany (1 center) and the USA (2 centers) between 28 June 2017 (first patient enrolled) and 13 February 2018 (last patient completed trial). | |||||||||||||||||||||||||||

Blinding implementation details |
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. Since the products were not identical in appearance, unblinded trial personnel were responsible for the handling, preparation and administration of IMP.

Overall ADA [1] | ||||||||||||||||||||||||
End point description |
For calculating the overall ADA incidence, patient numbers from both groups were summed and then divided by the number of evaluable patients. Baseline-positive patients without any samples available after IMP administration were excluded.
Numbers and percentages of incidences in each treatment group and the incidence difference between dasiglucagon and GlucaGen® with its 95% exact confidence limits were planned to be provided but were not generated because no ADA-positive patients occurred in the trial.

Date |
Amendment |
||
08 May 2017 |
In this substantial amendment, the following changes were made to the original protocol to revise details of the safety assessment of patients and correct changes, errors or inconsistencies in the description of the operational set up of the trial:
• Clarification on the statistical method and anti-drug antibody (ADA) assays
• Update of exclusion criterion on blood pressure
• Update of exclusion criterion on alcohol/drug abuse
• Specification of prohibited concomitant medication
• Additional ECG assessment added
• Clinical event of interest added
• Treatment options for patients experiencing hypo- or hyperglycemia prior dosing
• Monitoring of patients’ electrolyte levels
• Monitoring of potential pregnancies
• Additional visits required for patients discontinuing treatment prematurely
• Specification on time windows for assessments
• Specification of the requirements at the dosing visits
• Responsibility of unblinded trial personnel
• Randomization of replacement patients
• Clarification to the reporting of (Serious) Adverse Events
• Clarification on case report forms
• Subgroup analysis added to the statistical section
• Administrative changes
|
||
21 Aug 2017 |
This substantial amendment was prepared in order to investigate how pharmacodynamic and pharmacokinetic endpoints correlate with potential anti-drug antibody responses that may develop. In order to investigate this in patients that may develop antibodies late during the course of the trial, an extra visit was to be implemented for patients, who developed anti-drug antibodies after trial drug administration. The amendment also included an additional pharmacodynamic endpoint and specified that patients who discontinue the trial prematurely were not to be replaced. |

Interruptions (globally) |

Were there any global interruptions to the trial? No | |||
Limitations and caveats |
