Pen-Administered Low-Dose Dasiglucagon for Prevention and Treatment of Hypoglycemia in People With Type 1 Diabetes

A randomized, open-label, two-arm, two-week crossover study will be conducted to assess the study objectives. The study will enroll 24 participants with insulin pump-treated type 1 diabetes. Upon study enrollment, participants will complete two consecutive 2-week periods - a 'usual care' period and 'dasiglucagon' period. During the 'usual care' period, participants will manage episodes of manifest or impending hypoglycemia as usual, e.g. through carbohydrate consumption or manual insulin pump suspension. During the 'dasiglucagon' period, participants will use pen-administered low-dose dasiglucagon to treat or prevent episodes of hypoglycemia.

• HbA1c ≤ 70 mmol/l (8.5%)
• Performs aerobic exercise on a regular basis (≥ 2 times per week; self-reported) and desires to exercise per American Diabetes Association guidelines (150 minutes per week) during the study.
• Use of carbohydrate counting and bolus calculator (self-reported)
• Sensor glucose level < 3.9 mmol/l on ≥ 4/14 previous days assessed by CGM data

Exclusion criteria

• Use of anti-diabetic medicine (other than insulin), corticosteroids or other drugs affecting glucose metabolism during the study period and within 30 days prior to study start
• Known or suspected allergies to glucagon or related products
• History of hypersensitivity or allergic reaction to dasiglucagon or any of the excipients
• Patients with pheochromocytoma or insulinoma
• Hypoglycemia unawareness
• Females of childbearing potential who are pregnant, breast-feeding or intend to become pregnant or are not using adequate contraceptive methods
• Inability to understand the individual information and to give informed consent
• Current participation in another clinical trial that, in the judgment of the investigator, will compromise the results of the study or the safety of the subject
• Concomitant medical or psychological conditions identified through review of medical history, physical examination and clinical laboratory analysis that, according to the investigator's assessment, makes the individual unsuitable for study participation
