A Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic Activity of Very Low Dose-Glucagon in Subjects With Type 1 Diabetes Mellitus

August 21, 2006 updated by: DiObex

A Phase 1b, Single-Blind Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic Activity of Three Separate Dose Levels of Very Low Dose-Glucagon Administered Subcutaneously Overnight for 6, 9 or 12 Hours in Subjects With Type 1 Diabetes Mellitus

The purpose of this study is to identify the safest dose of very low dose glucagon to prevent hypoglycemia in patients with Type I diabetes who use insulin pumps and to measure the the amount of glucagon in the blood and see how the body responds to the glucagon.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Glucagon is currently used to treat severe hypoglycemia. DiObex believes that glucagon replacement therapy with very low doses of glucagon may prevent hypoglycemia without compromising effective glycemic control by insulin. In this study very low doses of glucagon will administered to Type I diabetics who use insulin pumps. The glucagon will be administered subcutaneously overnight for 6, 9 or 12 hours to see if the number of mild or impending hypoglycemia events can be safely decreased. Three different doses of glucagon will be compared to a control infusion.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
1) Evaluate the safety and tolerability of VLD-glucagon in doses of 2, 4 and 8 ng/kg/minute when infused overnight 2) Evaluate the PK profile in plasma of VLD-glucagon 3) Evaluate the pharmacodynamic activity of these doses by measuring glucose levels

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Compare the number of times and amount of time subjects have glucose levels < 70 mg/dL when treated with VLD-glucagon vs. the control infusion
