Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Two subjects completed the informed consent/assent process and entered the A2171083 study but none received treatment. The first subject withdrew consent during the Baseline Run-in period which was prior to Randomization. The second subject screen failed at Visit 1. Location = UNITED STATES.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Pfizer announced in Oct 2007 that it would stop marketing Exubera. At that time recruitment was placed on hold. Nektar, the company from which Pfizer licensed Exubera, announced on April 9, 2008 that it had stopped its search for a new marketing partner. As a result, study A2171083 was terminated and no further recruitment took place.
