- The toleration and safety of inhaled insulin therapy and its effects after 6 months, if any, on measures of pulmonary function.
- Conditions
- Diabetes Mellitus, Type 1
- Being tested
- Inhaled human insulin
- Medical subject headings
- Diabetes Mellitus, Type 1
What participants receive

What is being measured
The primary outcome is the main question the study is designed to answer.
Primary outcome is 24 week change in baseline in HbA1c
Secondary outcomes (10)
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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Inhaled human insulin in people with Diabetes Mellitus, Type 1, run by Pfizer at 36 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 2 inclusion and 3 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 13 Feb 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 36 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Primary outcome is 24 week change in baseline in HbA1c. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 13 Feb 2007.
