Study summary

To assess the impact of inhalation of insulin on glucose disposition in patients with type 1 diabetes

Read the detailed description

The study was terminated on Oct. 28, 2007. The protocol was undergoing implementation and methodological issues with major revisions that qualified this trial as a new trial. Pfizer decided to cancel new trials because of the decision to withdraw Exubera due to lack of market performance and not for safety reasons.
