About this study

The original protocol was a randomized, open-label, 3-way cross-over study with 9 scheduled visits. The visits comprised an initial screening visit, 3 treatment visits for the meal challenge followed by a 2-6-week blood-loss recovery period, an interim safety visit, 3 sequential visits for the glucose clamp, and a final close-out visit.

Protocol Amendment 1 was a randomized, open-label, 2-way cross-over study with 7 visits for each completed subject. The visits comprise an initial screening visit, 2 treatment visits for the meal challenge followed by a 2-6-week blood-loss recovery period, an interim safety visit, 2 sequential visits for the glucose clamp, and a final close-out visit.

For both the original protocol and Protocol Amendment 1, subjects were hospitalized in the clinical unit for all procedures.

The original protocol was a randomized, open-label, 3-way cross-over study with 9 scheduled visits. The visits comprised an initial screening visit, 3 treatment visits for the meal challenge followed by a 2-6-week blood-loss recovery period, an interim safety visit, 3 sequential visits for the glucose clamp, and a final close-out visit.

After review of the meal challenge data from the Original Protocol design, it became apparent that the TI Inhalation Powder, insulin lispro, and Exubera doses were not well matched, and resulted in significantly higher insulin exposure following insulin lispro than the two inhaled treatments. All meal challenge visits were completed for the 18 subjects enrolled. However, the glucose clamp visits were discontinued since it was discovered that a direct comparison between the treatments was not possible.

The protocol was amended (Amendment 1) to ensure that the insulin exposures between TI Inhalation Powder and insulin lispro were more suited (increased the TI Inhalation Powder doses and decreased the insulin lispro dose). An Exubera arm was not included in Amendment 1 due to the market removal of this product.

Protocol Amendment 1 was a randomized, open-label, 2-way cross-over study with 7 visits for each completed subject. The visits comprise an initial screening visit, 2 treatment visits for the meal challenge followed by a 2-6-week blood-loss recovery period, an interim safety visit, 2 sequential visits for the glucose clamp, and a final close-out visit.

For both the original protocol and Protocol Amendment 1, subjects were hospitalized in the clinical unit for all procedures.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Technosphere Insulin in people with Diabetes Mellitus, Type 2, run by Mannkind Corporation at 1 site in Germany.

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 5 inclusion and 31 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 16 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 Germany. 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 16 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?

Time to Minimum Endogenous Glucose Production (EGP) - Meal Challenge (time frame: 0-480 minutes). 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 16 Oct 2014.
