Exubera vs Lispro in a Lantus-based Regimen for Improved Glycemic Control in Type 2 Diabetes

Change in mean glycosylated hemoglobin A1c (HbA1c %) from Baseline to each visit through Week 24. Change = mean value at observation minus mean value at Baseline.

Number of subjects acheiving glycemic control: HbA1c target levels of <7.0%, <6.5%, and <6.0% at Week 24.

Number of subjects that attained HbA1c target levels of <7%, < 6.5%,and <6.0% at Week 24 without an episode of severe hypoglycemia.

Mean change from Baseline in fasting and 2-hour postprandial glucose at each visit in 8-point self-monitored blood glucose (SMBG) profiles: includes values prior to each meal (breakfast, lunch and dinner), 2 hours after each meal, at bedtime, and at 2:00 ante meridiem (a.m.) Change=observation value minus Baseline value.

Change from Baseine in fasting and postprandial plasma glucose as determined by standardized meal tolerance tests (MTT). Change = mean value at Week 12 minus mean value at Baseline. Time 0 results are for MTT (time 0) and non MTT (implied time 0) subjects.

Change from Baseline in fasting and postprandial plasma glucose as determined by standardized meal tolerance tests (MTT). Change = mean value at Week 24 minus mean value at Baseline. Time 0 results are for MTT (time 0) and non MTT (implied time 0) subjects.

Change from Baseline in fasting and postprandial lipids at Week 12 and Week 24 as determined by standard meal tolerance tests. Change = value at observation minus value at Baseline. Postprandial = 120 mins after meal.

Cardiovascular risk markers included serum high-sensitivity C-reactive protein (hs-CRP)[mg/L], leptin (ng/mL), adiponectin (ug/mL), and spot urine microalbumin. Change = observation of mean fasting and postprandial markers of cardiovascular risk at Week 12 and Week 24 minus mean Baseline observation.

Change = mean body weight at observation minus mean body weight at Baseline.

Change from baseline in fasting plasma lipids at Week 12 and Week 24. Change = observation mean minus Baseline mean.

Change from Baseline in insulin glargine at each visit. Change = mean at observation minus mean Baseline observation. Basal dose = injection of basal insulin (IU) (insulin glargine).

Dose of inhaled insulin prior to each meal at each visit.

Severe event = subject unable to treat self, at least 1 neurological symptom (memory loss, confusion, uncontrollable/irrational behavior, difficulty awakening, suspected seizure, loss of consciousness), and blood glucose <= 49 milligrams per deciliter (mg/dL) or not measured but clinical manifestations reversed by oral carbohydrates or glucose. Non-severe events = events that were mild-moderate.

Total number and severity of hypoglycemic events. Severe events = subject unable to treat self, at least 1 neurological symptom (memory loss, confusion, uncontrollable or irrational behavior, difficulty awakening, suspected seizure, loss of consciousness), and blood glucose <= 49 milligrams per deciliter (mg/dL) or not measured but clinical manifestations reversed by oral carbohydrates or glucose. Non-severe events = events that were mild or moderate.

Subject months of treatment = number of days from start of treatment to last day of active treatment + 1 day lag (total number of subjects treated * days treated), including off-drug time)/30.44. Severity: severe = subject unable to treat self, had at least 1 neurological symptom (memory loss, confusion, uncontrollable/irrational behavior, difficulty awakening, suspected seizure, loss of consciousness), and blood glucose <= 49 milligrams/deciliter; or not measured but clinical manifestations were reversed by oral carbohydrates or glucose. Non-severe events = events that were mild or moderate.

Crude event rate = (number of events)/(subject months); severe hypoglycemic events: crude event rate = (number of events)/(100 subject months). Severe = subject unable to treat self, at least 1 neurological symptom (memory loss, confusion, uncontrollable or irrational behavior, difficulty awakening, suspected seizure, loss of consciousness), and blood glucose <= 49 milligrams per deciliter (mg/dL) or unmeasured but clinical manifestestation reversed by oral carbohydrates or glucose. Non-severe events = mild-moderate.

Patient Satisfaction with insulin treatment Questionnaire (PSIT): 15-item self administered questionnaire that measures global satisfaction and two domains (subscales): convenience/ease of use and social comfort in people with type 1 and type 2 diabetes. 5-point Likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). The scoring of responses to each item is analyzed so that a higher item score indicates more satisfaction. Change = mean Patient Satisfaction of Insulin Treatment (PSIT) score at observation minus mean score at Baseline.

Change = difference in mean Patient Satisfaction with Insulin Treatment (PSIT) score from Week 4 to Week 24.

Mean of 24-hour Continuous Glucose Monitoring (CGMS) glucose values. Change from Baseline = mean at observation minus mean Baseline value.

Mean change in standard deviation of all blood glucose values within 24-hour period. Change = mean at observation minus mean at Baseline.
