E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To examine the effects of prandially inhaled TI Inhalation Powder in combination with an antidiabetic regimen of insulin and/or oral antidiabetic agents (TI Inhalation Powder group) versus antidiabetic treatment without TI Inhalation Powder (Usual Care [UC] group) on lung function and pulmonary safety in type 1 or type 2 diabetic, currently nonsmoking subjects with asthma or COPD. |

E.2.2 | Secondary objectives of the trial |
To compare between the treatment groups the effect of treatment on:
• Frequency of protocol-defined nonsevere and severe asthma or COPD exacerbations

• Change in health-related quality of life as assessed by the St. George’s Respiratory Questionnaire (SGRQ)
• Change in asthma control as measured by the Asthma Control Questionnaire (ACQ; for asthma subjects only)
• Glycemic control, expressed as the percentage (%) change of glycated hemoglobin (HbA1c)
• Incidence and frequency of defined hypoglycemia events
• Other safety and tolerability outcomes

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the comparison between the TI Inhalation Powder and UC treatment groups, with respect to change in postbronchodilator FEV1 from Screening/Visit 1 (Week -4) to Final Treatment/Visit 12 (Week 52). This will be measured at the pulmonary function laboratory (PFL). |

|
E.5.2 | Secondary end point(s) |

• Changes in postbronchodilator TLC and DLco from Visit 1 to Visit 12
• Incidence of protocol-defined nonsevere and severe asthma and COPD exacerbations
• Acute change in FEV1 from 15 minutes before to 15, 30, 60, or 120 minutes after TI Inhalation Powder administration (measured at the clinic using office spirometry in the TI Inhalation Powder group only)
