| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To compare the effect of low-dose glucagon (single 150 µg dose) administered immediately before aerobic exercise (visit B) versus a control trial without glucagon (visit C) on glucose responses during and after exercise   in individuals with AHCL-treated T1D. |  | 
| E.2.2 | Secondary objectives of the trial |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| •	Age ≥ 18 years •	Type 1 diabetes ≥ 2 years
 •	Using the AHCL system MiniMed 780G ≥ 4 weeks
 •	Novorapid use ≥1 week
 
 
 |  | 
| E.4 | Principal 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)
 •	Inability to understand the individual information and to give informed consent

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Difference in percentage of time in target glucose range (PG: 3.9 - 10.0 mmol/l) during and for 1-hour after dynamic physical exercise (0 min to +105min) between visits B and C. 
 |  | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| From 105 min post-intervention |  | 
| E.5.2 | Secondary end point(s) |

 •	Time (min) to hypoglycaemia (PG<3.9 mmol/l) (0 min to +105min)
 •	Percentage of time below target glucose range (PG<3.9 mmol/l) (0 min to +105min)
 •	Percentage of time above target glucose range (PG>10.0 mmol/l) (0 min to +105min)
 •	Incidence rate of hyperglycaemia (PG>10.0 mmol/l) (0 min to +105min)
 •	Nadir PG concentration (0 min to +105min)

 •	PG Area Under the Curve (AUC) (0 min to +105min)
 •	Standard deviation in PG concentrations (0 min to +105min)
 •	Coefficient of variation in PG concentrations (0 min to +105min)
