Brief Summary

Impaired awareness of hypoglycemia is common in type 1 diabetes (T1DM) patients. Impaired hypoglycemia awareness increases severe hypoglycemia risk by six-fold. Severe hypoglycemia compromises quality of life and can potentially cause death. The long-term goal of this pilot study is to lead to the development of novel therapeutic approaches to improve hypoglycemia awareness and thus prevent severe hypoglycemia development in T1DM population with impaired awareness of hypoglycemia. It is hypothesized that propranolol will improve hypoglycemia recognition in T1DM. The specific aims of the study are to determine whether propranolol treatment improves subjects' recognition of hypoglycemic episodes, and improves hypoglycemic awareness scores; whether propranolol favorably increases hypoglycemia blood glucose nadir, decreases onset-to-treatment/recovery time (i.e. hypoglycemia duration), and reduces hypoglycemia/severe hypoglycemia frequency; and, whether propranolol reduces fear of hypoglycemia and improves overall blood glucose control.

Outcome Measures

Primary Outcomes (1)

  • Ratio of Self-reported Hypoglycemic Episodes to Total Hypoglycemic Episodes Determined by Continuous Glucose Monitoring (CGM)

    A subject's self-reported hypoglycemic episode is defined by a hypoglycemic symptom record on the hypoglycemia diary with a confirmatory glucose value (glucometer value \< 70 mg/dL), or an incidental glucometer value \< 70 mg/dL if no hypoglycemia symptom develops. A single CGM hypoglycemic episode is defined by any CGM readings \< 70 mg/dL, followed by at least one reading ≥ 70 mg/dL from the Dexcom Professional Mobile CGM system. Self-reported and CGM assessment of hypoglycemic episodes will be conducted for two weeks before study drug intervention and two weeks after study drug intervention. The average change in the ratio of self-reported hypoglycemic episodes to total (CGM) episodes will be compared between the propranolol and placebo treatment arms

    2 weeks
