Brief Summary:
This is a non-inferiority, multi-center, randomized, controlled, single-blind, two-way crossover efficacy and safety study in subjects with Type 1 diabetes mellitus. The study involves two daytime clinical research center (CRC) visits with random assignment to receive G-Pen™ glucagon 1 mg during one period and Lilly Glucagon 1 mg during the other. Each daytime visit is preceded by an overnight stay in the CRC. In the morning of the inpatient study visit, the subject is brought into a state of hypoglycemia through IV administration of regular insulin diluted in normal saline. After a hypoglycemic state with plasma glucose < 50 mg/dL is verified, the subject is administered a dose of G-Pen or Lilly Glucagon via subcutaneous injection. Plasma glucose levels are monitored for up to 180 minutes post-dosing, with a value of >70.0 mg/dL within 30 minutes of glucagon administration indicating a positive response. After 3 hours, the subject is given a meal and discharged when medically stable. After a wash-out period of 7 to 28 days, subjects return to the CRC, and the procedure are repeated with each subject crossed over to the other treatment. A follow-up visit as a safety check is conducted 2-7 days following administration of the final dose of study drug.

Primary Outcome Measures :
  1. Number of Subjects With a Positive Glucose Response [ Time Frame: 0 to 30 minutes post dose ]
    Increase in plasma glucose concentration from below 50.0 mg/dL to greater than 70.0 mg/dL within 30 minutes after receiving glucagon


Secondary Outcome Measures :
  1. Time for Positive Glucose Response [ Time Frame: 0 to 180 minutes post dose ]
    Time from administration of glucagon for plasma glucose to rise from below 50.0 mg/dL to above 70.0 mg/dL

  2. Number of Subjects With a Positive Response for the Combination Endpoint: Positive Glucose Response/Positive Glucose Increase [ Time Frame: 0 to 30 minutes post dose ]
    A positive response for this endpoint is a return of plasma glucose to > 70 mg/dL or an increase in plasma glucose by ≥20 mg/dL within 30 minutes after receiving glucagon

  3. Number of Subjects With a Positive Glucose Increase [ Time Frame: 0 to 30 minutes post dose ]
    Increase in plasma glucose by ≥ 20.0 mg/dL within 30 minutes after receiving glucagon

  4. Time for Positive Glucose Increase [ Time Frame: 0 to 180 minutes post dose ]
    Time from administration of glucagon for plasma glucose to increase by ≥20 mg/dL from baseline

  5. Number of Subjects With a Positive Response for the Combination Endpoint: Positive Glucose Response/Relief of Neuroglycopenic Symptoms [ Time Frame: 0 to 30 minutes post dose ]
    A positive response for this endpoint is a return of plasma glucose to > 70 mg/dL or clearance of all neuroglycopenic symptoms of hypoglycemia within 30 minutes after receiving glucagon. Four symptoms were assessed: dizziness, blurred vision, difficulty in thinking and faintness.

  6. Number of Subjects With Relief of Neuroglycopenic Symptoms [ Time Frame: 0 to 30 minutes post dose ]
    Clearance of all neuroglycopenic symptoms of hypoglycemia within 30 minutes after receiving glucagon. Four symptoms were assessed: dizziness, blurred vision, difficulty in thinking and faintness.

  7. Time to Resolution of Autonomic Symptoms [ Time Frame: 0 to 180 minutes post dose ]
    Time from administration of glucagon to complete resolution of 4 autonomic symptoms of hypoglycemia. Symptoms included: sweating, tremor, palpitations and feeling of nervousness.

  8. Time to Resolution of Neuroglycopenic Symptoms [ Time Frame: 0 to 180 minutes post dose ]
    Time from administration of glucagon to complete resolution of 4 neuroglycopenic symptoms of hypoglycemia. Four symptoms were assessed: dizziness, blurred vision, difficulty in thinking and faintness.

  9. Time to Resolution of the Feeling of Hypoglycemia [ Time Frame: 0 to 180 minutes post dose ]
    Time from administration of glucagon to resolution of the overall sensation of hypoglycemia. Subjects were asked to answer yes/no to the question, "Do you feel hypoglycemic?" The time point as which the subject first answered "no" was considered the time of resolution.

  10. Glucose AUC [ Time Frame: 0 to 180 minutes post dose - Blood samples for assessment of blood glucose concentration were collected every 5 minutes post-dose to 90 minutes, and then at 120, 150 and 180 minutes post dose. ]
    Area under the curve for plasma glucose.

  11. Glucose Cmax [ Time Frame: 0 to 180 minutes post dose - Blood samples for assessment of blood glucose concentration were collected every 5 minutes post-dose to 90 minutes, and then at 120, 150 and 180 minutes post dose. ]
    Maximum concentration of plasma glucose.

  12. Glucose Tmax [ Time Frame: 0 to 180 minutes post dose ]
    Time to maximum concentration of plasma glucose. Blood samples for assessment of blood glucose concentration were collected every 5 minutes post-dose to 90 minutes, and then at 120, 150 and 180 minutes post dose.

  13. Glucagon Preparation and Administration Time [ Time Frame: 0 to 5 minutes pre-dose ]
    Time required to prepare and inject glucagon as measured between a "decision to dose" and completion of the injection
