What is being measured

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

  1. Dose-corrected area-under-the serum insulin concentration vs. time curve (AUC0-540 min) for inhaled Technosphere® Insulin compared to that of subcutaneous regular human insulin

    Measured: crossover approx every 2 weeks for up to 10 weeks

  2. Area under the glucose infusion rate (GIR AUC0-540 min) for Technosphere® Insulin compared to regular human insulin

    Measured: crossover approx every 2 weeks for up to 10 weeks

  3. Intra-patient and inter-patient comparison of CV % between treatments was based on a t-test.for bioavailability (ie, SI AUC0-540 min) & bioeffect (ie, GIR AUC0-540 min)

    Measured: crossover approx every 2 weeks for up to 10 weeks

Secondary outcomes (2)
  1. Safety variables included adverse events, HbA1c, pulmonary function tests, and diabetes-specific signs (ie, hypoglycemia and hyperglycemia)

    Measured: crossover approx every 2 weeks for up to 10 weeks

  2. Safety variables included adverse events (AEs), clinical laboratory tests, HbA1c, pulmonary function tests, electrocardiograms, vital signs, physical examinations, and diabetes-specific signs

    Measured: crossover approx every 2 weeks for up to 10 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Technosphere Insulin and Actrapid in people with Type 2 Diabetes Mellitus, run by Mannkind Corporation.

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 10 inclusion and 20 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 29 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Dose-corrected area-under-the serum insulin concentration vs. time curve (AUC0-540 min) for inhaled Technosphere® Insulin compared to that of subcutaneous regular human insulin (time frame: crossover approx every 2 weeks for up to 10 weeks). The study lists 3 primary outcomes in all. 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 29 Jun 2011.
