Primary Outcome Measures:
  • Change in HbA1c (%) From Baseline to Week 16 [ Time Frame: Baseline to Week 16 ]
    Change from Baseline in glycated hemoglobin at Week 16


Secondary Outcome Measures:
  • To Evaluate the Effect of Each Treatment on HbA1c [ Time Frame: Change from baseline to 16 weeks ]
    Not analyzed due to early termination of the trial.

  • Comparison of Fasting Plasma Glucose (FPG) Levels at Randomization and Throughout the Study [ Time Frame: Change from baseline to 16 weeks ]
    Not analyzed due to early termination of the trial.

  • Comparison of Post-prandial Glucose (PPG) Levels at Randomization and Throughout the Study [ Time Frame: Change from baseline to 16 weeks ]
    Not analyzed due to early termination of the trial.

  • Glycomark and Fructosamine Levels Measured Throughout the Study [ Time Frame: Change from baseline to 16 weeks ]

  • Seven-point Glucose at Randomization and Throughout the Study [ Time Frame: Change from baseline to 16 weeks ]

    Not analyzed due to early termination of the trial.

  • Changes in Body Weight at 16 Weeks [ Time Frame: Change from baseline to 16 weeks ]
    Not analyzed due to early termination of the trial.

  • Treatment Satisfaction as Assessed by Subject Treatment and Health Outcomes Questionnaires [ Time Frame: Change from baseline to 16 weeks ]
    Not analyzed due to early termination of the trial.

  • Total Number of Cough Episodes [ Time Frame: Baseline to Week 16 ]
    Total number of times patients coughed once, intermittently or continuously (inclusive)

  • Severe Hypoglycemic Event Rate [ Time Frame: Baseline to Week 16 ]

    Severe hypoglycemic event rate, ie, total number of events divided by subject-months of observation

    Severe hypoglycemia is defined as a subject who requires the assistance of another individual (not merely requested) and either:

    • SMBG levels ≤ 36 mg/dL OR
    • There is a prompt response to the administration of carbohydrate, glucagon, or other resuscitative measures

  • Mild or Moderate Hypoglycemic Event Rate [ Time Frame: Baseline to Week 16 ]

    Mild or moderate hypoglycemic event rate, ie, total number of events divided by subject-months of observation

    Nonsevere hypoglycemia is defined as a subject:

    • SMBG levels < 70 mg/dL AND/OR
    • Symptoms that are relieved by the self-administration of carbohydrates

  • Number of Subjects Reporting Cough Episodes [ Time Frame: Baseline to Week 16 ]
    Number of Subjects Reporting Cough Episodes

  • Number of Subjects Reporting Intermittent Coughing Episodes [ Time Frame: Baseline to Week 16 ]
    Number of subjects reporting Intermittent Coughing Episodes

  • Number of Single Coughing Episodes [ Time Frame: Baseline to Week 16 ]
    Total number of times patients coughed only once

  • Number of Cough Episodes Occuring Within 10 Minutes of Drug Inhalation [ Time Frame: Baseline to Week 16 ]
  • Baseline Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: Baseline ]
    Baseline FEV1

  • Week 16 Forced Expiratory Volume in 1 Second [ Time Frame: Week 16 ]
    Week 16 FEV1

  • Week 16 Change From Baseline in Forced Expiratory Volume in 1 Second [ Time Frame: Baseline to Week 16 ]
    Week 16 Change from Baseline in FEV1

  • Week 20 (Follow-up) Forced Expiratory Volume in 1 Second [ Time Frame: Week 20 (Follow-up) ]
    Week 20 (Follow-up) FEV1, 4 weeks after discontinuation of study treatment

  • Week 20 (Follow-up) Change From Baseline in Forced Expiratory Volume in 1 Second [ Time Frame: Baseline to Week 20 ]
    Week 20 (Follow-up, 4 weeks after discontinuation of study treatment) Change from Baseline in FEV1

  • Baseline Forced Vital Capacity (FVC) [ Time Frame: Baseline ]
    Baseline FVC

  • Week 16 Forced Vital Capacity [ Time Frame: Week 16 ]
    Week 16 FVC

  • Week 16 Change From Baseline Forced Vital Capacity [ Time Frame: Baseline to Week 16 ]
    Week 16 Change from Baseline FVC

  • Week 20 (Follow-up) Forced Vital Capacity [ Time Frame: Week 20 ]
    Week 20 (Follow-up, 4 weeks after discontinuation of study treatment) FVC

  • Week 20 (Follow-up) Change From Baseline in Forced Vital Capacity [ Time Frame: Baseline to Week 20 ]
    Week 20 (Follow-up, 4 weeks after discontinuation of study treatment) Change from Baseline in FVC
