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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TI Inhalation Powder and Humalog (Amendment 1)Drug
Subcutaneous (sc) rapid acting analog to be administered at one half of the meal challenge visits 15 minutes before a meal. Only the last 5 - 10 patients (Type 2) will be undergoing this amendment to the protocol.
TI Inhalation Powder (original protocol)Drug
Inhaled insulin technology to be administered immediately before a meal (prandially) for glucose control in Type 1 or Type 2 diabetics
| Study group | Role | What they receive |
|---|---|---|
| TI Inhalation Powder (original protocol) | Experimental | Under the original protocol, subjects with Type 1 and Type 2 diabetes will have TI Inhalation Powder administered prandially during dose optimization visits and meal challenge visits (with meals of varying carbohydrate contents). Subjects with Type 2 diabetes will also use TI Inhalation Powder daily at each meal between visits. Receives: Drug: TI Inhalation Powder (original protocol) |
| TI Inhalation Powder and Humalog (Amendment 1) | Other | Under Amendment 1, TI Inhalation Powder will be administered prandially to a new subset of subjects with Type 2 diabetes during TI dose optimization visits and TI meal challenge visits (with meals of varying carbohydrate contents). Subjects will be crossed over to administration of Humalog 15 minutes before meals during Humalog dose optimization visits and Humalog meal challenge visits (with meals of varying carbohydrate contents). Subjects will also use TI Inhalation Powder daily at each meal between visits. Receives: Drug: TI Inhalation Powder and Humalog (Amendment 1) |

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.
