Outcome Measures
Primary Outcomes (3)
Dose-corrected area-under-the serum insulin concentration vs. time curve (AUC0-540 min) for inhaled Technosphere® Insulin compared to that of subcutaneous regular human insulin
crossover approx every 2 weeks for up to 10 weeks
Area under the glucose infusion rate (GIR AUC0-540 min) for Technosphere® Insulin compared to regular human insulin
crossover approx every 2 weeks for up to 10 weeks
Intra-patient and inter-patient comparison of CV % between treatments was based on a t-test.for bioavailability (ie, SI AUC0-540 min) & bioeffect (ie, GIR AUC0-540 min)
crossover approx every 2 weeks for up to 10 weeks
Secondary Outcomes (2)
Safety variables included adverse events, HbA1c, pulmonary function tests, and diabetes-specific signs (ie, hypoglycemia and hyperglycemia)
crossover approx every 2 weeks for up to 10 weeks
Safety variables included adverse events (AEs), clinical laboratory tests, HbA1c, pulmonary function tests, electrocardiograms, vital signs, physical examinations, and diabetes-specific signs
crossover approx every 2 weeks for up to 10 weeks

Interventions
Eligibility Criteria
You may qualify if:
- Clinical Diagnosis of type 2 diabetes mellitus
- Current regimen of intensified insulin therapy (defined as separate injections of basal and prandial insulin with at least three injections per day) for at least six months prior to the study, including the use of long-lasting insulin analogue glargine (Lantus)
- Patients must have been willing to withhold insulin glargine for 24 hours prior to study drug dosing
- to 65 years old
- Body Mass Index \<35kg/m2
- HbA1c\<9%
- Non-smoker for at least 2 years
- If medications (other than oral anti-diabetic agents) in addition to insulin were taken at screening, the patient had to be on a stable regimen as defined by continued use of the same dose of each medication for a period of at least 3 months immediately prior to study enrollment
- FVC, FEV1, and VC all \>80% of expected normal
- Written informed consent
You may not qualify if:
- Diabetes mellitus type 1
- Current treatment (within the last 30 days) with oral anti-diabetic agents
- Regular pre-prandial doses of regular subcutaneous insulin for more than 30 IU per meal
- Intake of any drug or herbal preparation that, in the evaluation of the investigator, may interfere with the interpretation of clinical trials results or that is known to cause clinically relevant interference with insulin action, glucose utilization or recovery from hypoglycemia (eg, systematic steroid)
- HIstory of hypersensitivity to the drug or to drugs with similar chemical structures
- Treatment with any investigation drug within 3 months prior to enrollment or during this study
- Progressive fatal disease
- History of malignancy within 5 years of study entry (other than basal cell carcinoma)
- History of drug or alcohol abuse
- Evidence of severe secondary complications of diabetes (neuropathy, nephropathy as evidenced by creatinine \>1.5 mg/dL for females or \>1.8 mg/dL for males, grade III or IV retinopathy, or severe peripheral vascular disease)
- Evidence of gastroparesis, orthostatic hypotension or hypoglycemia unawareness (autonomic neuropathy)
- Myocardial infraction or stroke within the preceding six months
- Positive hepatitis B (hepatitis B surface antigen) and /or hepatitis C (hepatitis C antibody) serology and /or positive HIV serology
- History of presence of clinically significant cardiovascular, hepatic (as evidenced by ALT or AST \>3 times the normal reference range), gastrointestinal, neurological, or infectious disorders capable of altering the absorption, metabolism or elimination of drugs, or constituting a significant risk factor when taking the study medications
- Anemia (hemoglobin concentrations \<11 g/dL for females of \<g/dL for males)
- +5 more criteria
