Six Month Clinical Trial Assessing Efficacy And Safety Of Inhaled Insulin In Type 1 Diabetes Mellitus.

February 9, 2007 updated by: Pfizer

Efficacy and Safety of Inhaled Compared With Subcutaneous Human Insulin Therapy in Subjects With Type 1 Diabetes Mellitus: A Six-Month, Outpatient, Parallel Comparative Trial

To determine, in subjects with Type 1 Diabetes Mellitus:

  1. Whether glycemic control can be achieved at least as effectively with an insulin regimen involving pre-meal inhaled insulin plus a single bedtime Ultralente injection as with a conventional subcutaneous insulin regimen involving 2-3 mixed Regular/NPH insulin injections per day.
  2. The toleration and safety of inhaled insulin therapy and its effects after 6 months, if any, on measures of pulmonary function.

Study Overview

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

12 years to 65 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

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
Primary outcome is 24 week change in baseline in HbA1c

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
The secondary endpoints include the following efficacy assessments:
Incidence of hypoglycemia
Proportion of subjects with acceptable glycemic control (e.g., HbA1c<8%)
Change from baseline in fasting lipid profile
Change from baseline in fasting plasma glucose level
Change from baseline in meal glucose response (2-hour postprandial increment in plasma glucose)
Dose of insulin (total dose of injected sustained-duration insulin, and total dose of inhaled or injected Regular insulin during the study).
Change from baseline in body weight
Change from baseline in 24-hour home glucose profile (based on the area under the glucose profile curve calculated by the trapezoid rule with special weights assigned to the pre-breakfast and bedtime assessments).
Patient satisfaction and preference.
