NCT03841526

Brief Summary

This study is a randomized, placebo-controlled, double-blind, 2-treatment, 2-period, crossover comparison in a clinical research center (CRC) setting, followed by a randomized, placebo-controlled, double-blinded, 2-arm parallel comparison with a third open-label arm in an outpatient setting. The purpose of the study is to evaluate the preliminary efficacy and safety of Glucagon Ready-to-Use \[RTU\] to prevent exercise-induced hypoglycemia (EIH) in adults with Type 1 diabetes mellitus (T1D), who perform regular, moderate-to-high intensity aerobic exercise.

Outcome Measures

Primary Outcomes (3)

  • Outpatient Phase: Incidence Rate of Hypoglycemia During and After Moderate to High Intensity Aerobic Exercise.

    Mean incidence rate of hypoglycemia during and after sessions of moderate to high intensity aerobic exercise in 12-week Outpatient Phase. Incidence rate is defined as the number of hypoglycemic events divided by the total number of qualified exercise sessions, assessed at group level. Qualified exercise session is: (1) confirmed blood glucose of 100-180 mg/dL prior to start of exercise, (2) self-administered study drug no more than 10 min prior to exercise (5 min target), (3) conducted a protocol allowed exercise of moderate to high intensity for at least 30 min and no longer than 75 min, and (4) achieved a target heart rate of 80% of maximum calculated heart rate at least once during session. Exercise sessions were to occur at least 2-3 times per week. Only 1 qualified exercise session/subject/day was included in the analysis (the first if \>1). Hypoglycemic event defined as any hypoglycemic event occurring within 30 (+2) min after completion of a qualified exercise session.

    Daily; During the 12-week Outpatient Phase qualified exercise sessions were assessed daily and associated hypoglycemia events were assessed continuously during and within the 30 (+2) minute period following a qualified exercise session.

  • Outpatient Phase: Mean Number of Hypoglycemic Events

    Outpatient Phase: Mean number of hypoglycemic events associated with the qualified exercise sessions, assessed at group level. A qualified exercise session was defined as one were (1) a confirmed blood glucose value of 100-180 mg/dL prior to start of exercise, (2) self-administered the study drug no more than 10 minutes prior to exercise (5 minutes was the target), (3) conducted a protocol allowed exercise for moderate to high intensity for at least 30 minutes and no longer than 75 minutes, and (4) achieved a target heart rate of 80% of maximum calculated heart rate at least once during the session. A hypoglycemic event was defined as any hypoglycemic event occurring during or within 30 (+2) minutes after completion of a qualified exercise session. Exercise sessions were expected to occur at least 2 to 3 times per week. Only 1 qualified exercise session per subject per day was included in the analysis (the first if \>1).

    Daily; During the 12-week Outpatient Phase qualified exercise sessions were assessed daily and associated hypoglycemia events were assessed continuously throughout the 30 (+2) minute period following a qualified exercise session.

  • Outpatient Phase: Mean Number of Qualified High Intensity Aerobic Exercise Sessions

    Outpatient Phase: Mean number of qualified exercise sessions, assessed at group level. A qualified exercise session was defined as one were (1) a confirmed blood glucose value of 100-180 mg/dL prior to start of exercise, (2) self-administered the study drug no more than 10 minutes prior to exercise (5 minutes was the target), (3) conducted a protocol allowed exercise for moderate to high intensity for at least 30 minutes and no longer than 75 minutes, and (4) achieved a target heart rate of 80% of maximum calculated heart rate at least once during the session. Exercise sessions were expected to occur at least 2 to 3 times per week. Only 1 qualified exercise session per subject per day was included in the analysis (the first if \>1).

    Daily; During the 12-week Outpatient Phase the occurrence of qualified exercise sessions were assessed daily.

Masking Details
CRC Phase was a fully masked double-blind crossover with each subject receiving each treatment 1 time. In the Outpatient Phase, the two arms with 50% insulin pump reduction were double-blind (fully masked) and the arm with Glucagon RTU and no insulin pump reduction was open-label.

Model Details: CRC Phase: randomized, placebo-controlled, double-blind, two-treatment, two-period, crossover comparison in a clinical research center (CRC) setting. The subjects were re-randomized into the Outpatient Phase: randomized, placebo-controlled, partially double-blind, 3-arm parallel comparison in an outpatient setting.
