A Study in Adults With Type 1 Diabetes

HbA1c is the glycosylated fraction of hemoglobin A which provides an estimate of a participant's blood sugar control over a 6- to 12-week period. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline HbA1c, treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

Blood samples are collected from participants and percentage of insulin antibody binding was measured to determine the insulin antibody levels. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

HbA1c is the glycosylated fraction of hemoglobin A which provides an estimate of a participant's blood sugar control over a 6- to 12-week period.

7-point SMBG measurements are completed at the following timepoints: Morning (AM) Pre-Meal, AM Post-Prandial (PP), Midday (MD) Pre-Meal, MD PP, Evening (EV) Pre-Meal, Bed Time and 0300 hours. PP glucose is measured 2 hours (hrs) after the start of the meal. Values for the 7-point SMBG profiles were averaged over the three 7-point SMBG profiles during 2-week period prior to each visit. If only 1 of the 3 days of data was collected, then the value of the 1 day was used. If only 2 of the 3 days of data were collected, then the average of the 2 days was used. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

Glycemic variability is the intra-participant standard deviation (SD) value of fasting blood glucose as measured by the actual morning premeal blood glucose value from the 7-point self-monitoring blood glucose (SMBG) profiles. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

ALBSS contains 33 items, with each item scored on a 5-point response scale: 0 (never) to 4 (almost always). Items are categorized in 2 domains: Behavior (or avoidance) Items 1 to 15 and Worry (or affect) Items 16 to 33. Behavior Total Score (TS) range is 0 to 60 and Worry TS range is 0 to 72. Higher scores on "Behavior" items (related to avoidance of hypoglycemia) reflect greater awareness and/or effort of the participant to prevent low blood sugar. Higher scores on "Worry" items (related to worries about low blood sugar and its consequences) reflect greater participant concern about having low blood sugar. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

ITSQ is a validated instrument containing 22 items that assess treatment satisfaction for participants with diabetes and on insulin. Items measured on a 7-point scale: 1 (no bother at all) to 7 (a tremendous bother), with lower scores reflecting better outcomes. Items divided into 5 domains: Inconvenience of Regimen [(IR) 5 items: scores range 5-35], Lifestyle Flexibility [(LF) 3 items: scores range 3-21], Glycemic Control [(GC) 3 items: scores range 3-21], Hypoglycemic Control [(HC) 5 items: scores range 5-35], Insulin Delivery Device [(IDD) 6 items: scores range 6-42]. ITSQ Total Overall Scores range from 22-154. Data presented are the transformed score on a scale of 0-100, where transformed score=100×[(7-raw score)/6]. Higher scores indicate better treatment satisfaction. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

Total daily insulin dose was adjusted for body weight [units of insulin/kilogram/day (U/kg/day)]. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

Units of insulin taken daily were presented. Least Squares (LS) means were calculated by analysis of covariance (ANCOVA) and adjusted for baseline hemoglobin A1c (HbA1c), treatment and time of basal insulin injection (daytime, evening/bedtime) and country.

HbA1c is the glycosylated fraction of hemoglobin A which provides an estimate of a participant's blood sugar control over a 6- to 12-week period. The percentage of participants with Hemoglobin A1c (HbA1c) <7.0% or HbA1c ≤6.5% is calculated as the number of participants with an HbA1c level of the cut-off value (<7.0% or ≤6.5%) divided by the number of participants treated, then multiplied by 100.

Incidence of hypoglycemic events is defined as the number of hypoglycemic events. A hypoglycemic event is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia, or has a blood glucose (BG) concentration of ≤ 70 milligrams/deciliter [mg/dL (3.9 millimoles/liter (mmol/L)], even if it was not associated with signs, symptoms, or treatment consistent with current guidelines [American Diabetes Association (ADA) 2005]. Severe hypoglycemia is defined as a hypoglycemic event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions (these episodes may be associated with sufficient neuroglycopenia to induce seizure or coma; also, BG measurements may not be available during such an event). Nocturnal hypoglycemia is defined as any hypoglycemic event that occurs between bedtime and waking.

The rate of hypoglycemic events per 30 days is defined as the total number of events between visits divided by the actual number of days between visits, and then multiplied by 30 days. A hypoglycemic event is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia, or has blood glucose (BG) concentration of ≤ 70 milligrams/deciliter [mg/dL (3.9 millimoles/liter (mmol/L)], even if it was not associated with signs, symptoms, or treatment consistent with current guidelines (ADA 2005). Severe hypoglycemia is defined as a hypoglycemic event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions (these episodes may be associated with sufficient neuroglycopenia to induce seizure or coma; also, BG measurements may not be available during such an event). Nocturnal hypoglycemia is defined as any hypoglycemic event that occurs between bedtime and waking.
