You may not qualify if…

Total daily insulin dose = 2 IU/kg/day. History of insulin pump use within 3 months of Screening or use of continuous glucose monitoring within 6 weeks of Screening
History of inhaled insulin use in the previous 6 months
Two or more unexplained severe hypoglycemic episodes within 3 months of Screening or an episode of severe hypoglycemia between Visit 1 and Visit 2. Unexplained refers to episodes of severe hypoglycemia that are not related to a dosing error, lack of or a change in meal size, or related to additional/unanticipated exercise
Any hospitalization or emergency room visit due to poor diabetic control within 6 months of Screening, or hospitalization or emergency room visit due to poor diabetic control between Visit 1 and Visit 2
Allergy or known hypersensitivity to insulin or to any of the drugs to be used in the study, or a history of hypersensitivity to TI Inhalation Powder or to drugs with a similar chemical structure
History of recent blood transfusions (within previous 3 months), hemoglobinopathies, or any other conditions that affect HbA1c measurements.
History of COPD, asthma, or any other clinically important pulmonary disease (eg, pulmonary fibrosis), or use of any medications for these conditions
Any clinically significant radiological findings on screening chest x-ray
Active respiratory infection within 30 days before Screening (subject may return after 30 days from resolution for rescreening)
Major organ system diseases, including: ? Seizure disorder; systemic autoimmune or collagen vascular disease requiring previous or current treatment with systemic corticosteroids, cytotoxic drugs, or penicillamine; cancer (other than excised cutaneous basal cell carcinoma) or any history of lung neoplasms
Current or previous chemotherapy or radiation therapy that may result in pulmonary toxicity; use of medications for weight loss (eg, sibutramine, orlistat) within 12 weeks of Screening; treatment with amiodarone within 12 weeks of Screening
Clinically significant abnormalities on screening laboratory evaluation or chest x-ray
Severe complications of diabetes, in the opinion of the PI, including symptomatic autonomic neuropathy; disabling peripheral neuropathy; active proliferative retinopathy; nephropathy with renal failure, renal transplant, or dialysis; nontraumatic amputations due to gangrene; or vascular claudication
Women who are pregnant, lactating, or planning to become pregnant during the clinical study period; women of childbearing potential (defined as premenopausal and not surgically sterilized or postmenopausal for fewer than 2 years) not practicing adequate birth control. Adequate birth control is defined as using oral, percutaneous, or transdermal contraceptives; condoms and diaphragms (double barrier) with a spermicide; or intrauterine devices. Postmenopausal for this study includes amenorrhea f
Current drug or alcohol abuse or a history of drug or alcohol abuse that, in the opinion of the PI, would make the subject an unsuitable candidate for participation in the study
Exposure to any investigational medications or devices within the previous 30 days before study entry
Unable to read or write, or unlikely to comprehend and follow the study protocol procedures; lack of compliance with medication or procedures that, in the PI's opinion, may affect the study data or subject safety and that precludes the subject from participation in the study; or any other concurrent medical or major psychiatric condition that, in the opinion of the PI, makes the subject unsuitable for the clinical study or could limit the validity of the informed consent or impair the subject'
