The purpose of this study is to evaluate pulmonary function test (PFT) sub-study in interested subjects from studies MKC-TI-161, MKC-TI-162 and MKC-TI-166. 100 Type I and 100 Type II diabetics will be enrolled. Each subject will undergo 6 PFT assessments over the course of the parent study.

This study is designed to evaluate and compare changes in pulmonary function (FEV1(forced expiratory volume in 1 second) FVC(forced vital capacity), TLC (total lung capacity) and DLco) in subjects enrolled in 1 of 3 parent trials (MKC-TI-161, MKC-TI-162 or MKC-TI-166). Up to 100 subjects with Type I and Type II diabetes in the TI Inhalation Powder arm, and 100 subjects with Type I and Type II diabetes in the comparator arm will be enrolled. Each subject will undergo 6 PFT assessments over the course of the parent trial.

Inclusion Criteria:

• Enrollment in one of three parent trials (MKC-TI-161, MKC-TI-162 or MKC-TI-166)

Exclusion Criteria:

• Subjects who are unable to perform PFTs that meet American Thoracic Society/European Respiratory Society (ATS/ERS) quality recommendations for acceptability and repeatability will be excluded from this study
