About this study

Official title: A Phase 2, Single-Center, Open-Label, Pharmacodynamic Clinical Trial to Evaluate the Effect of Technosphere® Insulin Inhalation Powder Safety and Efficacy of Technosphere® Insulin Inhalation Powder (TI Inhalation Powder) Safety and Efficacy of Technosphere® Insulin Inhalation Powder (TI Inhalation Powder) on Postprandial Glucose Levels in Subjects With Type 1 and Type 2 Diabetes Mellitus Ingesting Meals With Varied Carbohydrate Content

The purpose of this study is to determine if, once a favorable dose of TI Inhalation Powder is established for either a type 1 or 2 patient, based on a average diabetic meal, the patient's favorable dose can be used safely, regardless of change in meal carbohydrate content. Patients were randomly assigned to various carbohydrate loads (0%, 50%, 100%, 150% or 200%). The 100% carbohydrate load was determined based upon their standard insulin dose for their normal meal.

Being tested
TI Inhalation Powder and Humalog (Amendment 1), TI Inhalation Powder (original protocol)
Medical subject headings
Diabetes Mellitus, Type 2, Diabetes Mellitus, Type 1

What is being measured

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

  1. Lunch Plasma Glucose Time 0 Corrected AUC (0-240) - Original Protocol (TI Treated Type 1 Subjects)

    AUC (area under the plasma glucose - time curve) from time 0 (immediately before starting meal) to 240 minutes after the start of the meal when the curve is above time 0 value.

    AOC (area over the plasma glucose - time curve) from time 0 (immediately before starting meal) to 240 minutes after the start of the meal when the curve is below time 0 value.

    TIme 0 corrected AUC (0-240) = AUC - AOC

  4. Lunch Plasma Glucose Time 0 Corrected AUC(0-240) - Amendment 1 (Humalog Treated Type 2 Subjects)

    AUC (area under the plasma glucose - time curve) from time 0 (immediately before starting meal) to 240 minutes after the start of the meal when the curve is above time 0 value.

    AOC (area over the plasma glucose - time curve) from time 0 (immediately before starting meal) to 240 minutes after the start of the meal when the curve is below time 0 value.

    TIme 0 corrected AUC (0-240) = AUC - AOC

    Measured: 0 to 240 minutes

  5. Lunch Plasma Glucose Excursion - Original Protocol (TI Treated Type 1 Subjects)

    Excursion is the difference between plasma glucose Cmax and Cmin (Cmax - Cmin) at lunch

    Measured: 0 to 240 minutes

  6. Breakfast Plasma Glucose Excursion - Original Protocol (TI Treated - Type 1 Subjects)

    Excursion is the difference between plasma glucose Cmax and Cmin (Cmax - Cmin) at breakfast

    Measured: 0 to 240 minutes

  7. Lunch Plasma Glucose Excursion - Amendment 1 ( TI Treated Type 2 Subjects)

    Excursion is the difference between plasma glucose Cmax and Cmin (Cmax-Cmin) at lunch

    Measured: 0 to 240 minutes

  8. Lunch Plasma Glucose Excursion - Amendment 1 (Humalog Treated Type 2 Subjects)

    Excursion is the difference between plasma glucose Cmax and Cmin (Cmax-Cmin) at lunch

    Measured: 0 to 240 minutes

Secondary outcomes (4)
  1. Lunch Plasma Glucose AOC (0-240) - Original Protocol (TI Treated Type 1 Subjects)

    Area over the plasma glucose - time curve from time 0 (immediately before starting lunch) to 240 minutes after the start of the lunch

    Measured: 0 to 240 minutes

  2. Breakfast Plasma Glucose AOC(0-240) - Original Protocol (TI Treated Type 1 Subjects)

    Breakfast area over the plasma glucose - time curve from time 0 (immediately before breakfast) to 240 minutes after start of breakfast

    Measured: 0 to 240 minutes

  3. Lunch Plasma Glucose AOC(0-240) - Amendment 1 (TI Treated Type 2 Subjects)

    Lunch area over the plasma glucose - time curve from time 0 (immediately before breakfast) to 240 minutes after start of lunch

    Measured: 0 to 240 minutes

  4. Lunch Plasma Glucose AOC(0-240) - Amendment 1 (Humalog Treated Type 2 Subjects)

    Lunch area over the plasma glucose - time curve from time 0 (immediately before breakfast) to 240 minutes after start of lunch

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TI Inhalation Powder and Humalog (Amendment 1) and TI Inhalation Powder (original protocol) in people with Diabetes Mellitus, Type 2 and Diabetes Mellitus, Type 1, run by Mannkind Corporation at 1 site in United States.

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 6 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: stopped early, as of the sponsor's last update on 30 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 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?

Yes. Results are posted in the registry (first posted 21 Oct 2014). 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?

Lunch Plasma Glucose Time 0 Corrected AUC (0-240) - Original Protocol (TI Treated Type 1 Subjects) (time frame: 0 to 240 minutes). The study lists 8 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 30 Oct 2014.
