Descriptive Information
Brief Title  ICMJE Efficacy and Safety of Inhaled Insulin Compared With Subcutaneous Human Insulin Therapy in Adults With Type 2 Diabetes
Official Title  ICMJE Efficacy and Safety of Exubera® (Inhaled Insulin) Compared With Subcutaneous Human Insulin Therapy in Adult Subjects With Type 2 Diabetes Mellitus: A Long-Term, Outpatient, Open-Label, Parallel-Group Comparative Trial
Brief Summary

This study is being done to find out the good and bad effects of inhaled insulin that is used by oral inhalation, to adult males and females with type 2 diabetes mellitus. The other name for this inhaled insulin is Exubera®.

This study included a 2-year comparative treatment period followed by a 6-month follow-up period during which inhaled insulin-treated subjects were switched back to subcutaneous short-acting insulin. After this follow-up period, all eligible subjects entered a comparative extension period that was to last for 5 years. When the comparative portion of the study was terminated, all subjects were requested to return for a final extension follow-up month 3 visit.

Detailed Description Pfizer announced in October 2007 that it would stop marketing Exubera. Nektar, the company from which Pfizer licensed Exubera, announced on April 9, 2008 that it had stopped its search for a new marketing partner. Accordingly, there will be no commercial availability of Exubera. As a result, study A2171029 was terminated on June 9, 2008. Neither safety nor efficacy reasons were the cause of the study termination.
