About this study

Official title: G-Pen™ (Glucagon Injection) Compared to Lilly Glucagon (Glucagon for Injection [RDNA Origin]) for Induced Hypoglycemia Rescue in Adults With T1D: a Phase 3 B Multi-Centered, Randomized, Controlled, Single Blind, 2-Way Crossover Study to Evaluate Efficacy and Safety

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With a Positive Glucose Response

    Increase in plasma glucose concentration from below 50.0 mg/dL to greater than 70.0 mg/dL within 30 minutes after receiving glucagon

    Measured: 0 to 30 minutes post dose

Secondary outcomes (13)
  1. Time for Positive Glucose Response

    Time from administration of glucagon for plasma glucose to rise from below 50.0 mg/dL to above 70.0 mg/dL

    Measured: 0 to 180 minutes post dose

  2. Number of Subjects With a Positive Response for the Combination Endpoint: Positive Glucose Response/Positive Glucose Increase

    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

    Measured: 0 to 30 minutes post dose

  3. Number of Subjects With a Positive Glucose Increase

    Increase in plasma glucose by ≥ 20.0 mg/dL within 30 minutes after receiving glucagon

    Measured: 0 to 30 minutes post dose

  4. Time for Positive Glucose Increase

    Time from administration of glucagon for plasma glucose to increase by ≥20 mg/dL from baseline

    Measured: 0 to 180 minutes post dose

  5. Number of Subjects With a Positive Response for the Combination Endpoint: Positive Glucose Response/Relief of Neuroglycopenic Symptoms

    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.

    Measured: 0 to 30 minutes post dose

  6. Number of Subjects With Relief of Neuroglycopenic Symptoms

    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.

    Measured: 0 to 30 minutes post dose

  7. Time to Resolution of Autonomic Symptoms

    Time from administration of glucagon to complete resolution of 4 autonomic symptoms of hypoglycemia. Symptoms included: sweating, tremor, palpitations and feeling of nervousness.

    Measured: 0 to 180 minutes post dose

  8. Time to Resolution of Neuroglycopenic Symptoms

    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.

    Measured: 0 to 180 minutes post dose

  9. Time to Resolution of the Feeling of Hypoglycemia

    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.

    Measured: 0 to 180 minutes post dose

  10. Glucose AUC

    Area under the curve for plasma glucose.

    Measured: 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.

  11. Glucose Cmax

    Maximum concentration of plasma glucose.

    Measured: 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.

  12. Glucose Tmax

    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.

    Measured: 0 to 180 minutes post dose

  13. Glucagon Preparation and Administration Time

    Time required to prepare and inject glucagon as measured between a "decision to dose" and completion of the injection

    Measured: 0 to 5 minutes pre-dose

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing G-Pen and Lilly Glucagon in people with Insulin Hypoglycemia and Type 1 Diabetes Mellitus, run by Xeris Pharmaceuticals at 6 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects With a Positive Glucose Response (time frame: 0 to 30 minutes post dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03439072, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2020.
