About this trial
This is an interventional prevention trial for Type 1 Diabetes focused on measuring Type 1 Diabetes, Hypoglycemia, Exercise, Glucagon, Hybrid closed-loop system
Eligibility Criteria
Inclusion Criteria:
- Age ≥ 18 years
- Type 1 diabetes ≥ 2 years
- Use of AHCL system MiniMed 780G ≥ 4 weeks
- Use of Novorapid for ≥ 1 week
Exclusion Criteria:
- Allergies to lactose or glucagon
- Known or suspected allergies to glucagon or related products
- History of hypersensitivity or allergic reaction to glucagon or lactose
- Patients with diagnosed pheochromocytoma, insulinoma or gastroparesis
- 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
- Lack of compliance with key study procedures at the discretion of the investigator
- Females of childbearing potential who are pregnant, breast-feeding or intend to become pregnant or are not using adequate contraceptive methods (methods are considered adequate for study enrolment for females: an intrauterine device, hormonal contraception (birth control pills, implant, patch, vaginal ring or injection), a single partner who is sterile or infertile, or sexual abstinence. Contraception is required throughout the study duration. Sterilized or postmenopausal women (>12 months since last period) are not required to use contraception)

5. Study Description
Brief Summary
The primary aim of the study is to evaluate the glucose response to low-dose glucagon (single 150 µg dose) administered immediately before aerobic exercise in individuals with AHCL-treated T1D.
Detailed Description
The study consists of a screening visit (visit A), a cardiopulmonary exercise test (visit B) and a study visit (visit C). During study visit C, participants will receive s.c. administration of 150 ug glucagon prior to a 45-min moderate intensity continuous exercise session and subsequently continue into a 1-hour post-exercise observation period.
