COPD

• Physician diagnosis of COPD (including emphysema and/or chronic bronchitis), history of dyspnea and/or intermittent or daily chronic cough with or without sputum production, not attributable to any other known cause

• Postbronchodilator FEV1 ≥ 50% NHANES III predicted, total lung capacity (TLC) ≥ 80% predicted ITS, and DLco (unc) ≥ 50% predicted (Miller)

Both

• Clinical diagnosis of Type1 or 2 diabetes mellitus for ≥ 12 months and no change in anti-diabetic regiment for at least 90-days prior to screening

• Treatment with supplemental oxygen therapy, room air oxygen saturation, 94% or history of intubation or ICU admission for respiratory illness in the past 5 yrs.
• Greater than 2 hospitalizations or ER or urgent care visits or required >3 courses of systemic steroid in the past 12 months for respiratory illness
• Use of Symlin® (pramlintide acetate) within the preceding 90 days
• Two or more severe hypoglycemic episodes within 6 months of screening or episode of severe hypoglycemia between Screening and Baseline
• Previous exposure to any inhaled insulin product
• Currently using an insulin delivery pump
• Requires significant change (define as initiation of a new medication or change in the dose or frequency of the controller medications) in the asthma or COPD therapeutic regimen within 8 weeks of Screening/Visit 1 (Week -4) or between Visit 1 and Baseline/Visit 2
• Severe complications of diabetes mellitus, in the opinion of the PI or sub-investigator, including symptomatic autonomic neuropathy; disabling peripheral neuropathy; active proliferative retinopathy; nephropathy with renal failure, renal transplant and/or dialysis; history of foot ulcers; nontraumatic amputations due to gangrene; and/or vascular claudication
