Out-Patient Study in Patients With Type 2 Diabetes Mellitus Who Are Taking no Diabetes Medication or Metformin Only

HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over a 2- to 3-month period. The Baseline HbA1c value is defined as the last non-missing value before the start of treatment. Change from Baseline in HbA1c was calculated as the post-Baseline value minus the value at Baseline. The last observation carried forward (LOCF) method was used to impute missing data, in which the last valid observation recorded on treatment (scheduled or unscheduled) was used to impute the missing measurement. For participants who had missing observations before their last observation on treatment, the closest previous non-missing on-treatment observation was carried forward to missing visits. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing.

The number of participants who achieved target values for HbA1c (i.e., HbA1c <6.5% and >=6.5% to <7%) were assessed. The last observation carried forward (LOCF) method was used to impute missing data, in which the last valid observation recorded on treatment (scheduled or unscheduled) was used to impute the missing measurement. For participants who had missing observations before their last observation on treatment, the closest previous non-missing on-treatment observation was carried forward to missing visits. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing.

The FLIE questionnaire is used to record the participant's feelings/opinions concerning the effects of nausea/vomiting on their quality of life during the past five days. Participants completed the questionnaire by responding to 18 questions. The first set of 9 questions refer to nausea, and the second set of 9 questions refer to vomiting. Each question is scored on a seven-point visual analog scale (1 to 7). On this scale, a score of 1 corresponds to 0 millimeters (mm), and a score of 7 correspond to 100 mm. Anything in between is marked at the appropriate point on the scale and is measured in mm. Data are reported in mm in this table. In FLIE questions (FLIEQ) 1, 2, 4, 5, 7, 8, 9, 10, 12, 13, 14, 16, and 17, a score of 1 indicates no effect on the quality of life, and a score of 7 indicates a great effect on the quality of life. In FLIEQ 3, 6, 11, 15, and 18, a score of 1 indicates a great effect on the quality of life, and a score of 7 indicates no effect on the quality of life.

The HCFQ questionnaire is used to record how often participants have felt hungry or craved food, and how full participants felt after finishing meals, on average, in the past week. Participants answered the following seven questions with the response that best described their feelings of hunger, craving, and fullness: Q1, "In the past week I was hungry"; Q2, "In the past week I thought about food"; Q3, "In the past week I wanted to eat"; Q4, "In the past week I ate more than I should have"; Q5, "In the past week, I craved specific food"; Q6, "In the past week when finished meals I felt full"; Q7, "In the past week when finished meals I felt satisfied."

Clearance is defined as the volume of plasma cleared of albiglutide per unit time. Samples were collected prior to the administration of study medication on dosing days (Weeks 0, 4, 5, 7, 8, 9, 12, 15) and on the day of the clinic visit at Weeks 16, 17, 18, 20, 23, and 27. The Week 5, 8, and 12 post-dose pharmacokinetic (PK) sampling was performed within 6 days of drug administration.

Samples were collected prior to the administration of study medication on dosing days (Weeks 0, 4, 5, 7, 8, 9, 12, 15) and on the day of the clinic visit at Weeks 16, 17, 18, 20, 23, and 27. The Week 5, 8, and 12 post-dose (PK sampling was performed within 6 days of drug administration.

Absorption rate is defined as the rate at which albiglutide enters the blood circulation. Samples were collected prior to the administration of study medication on dosing days (Weeks 0, 4, 5, 7, 8, 9, 12, 15) and on the day of the clinic visit at Weeks 16, 17, 18, 20, 23, and 27. The Week 5, 8, and 12 post-dose (PK sampling was performed within 6 days of drug administration.

EC50 is defined as the concentration of albiglutide that give a half-maximal HbA1c and FPG response. Samples were collected prior to the administration of study medication on dosing days (Weeks 0, 4, 5, 7, 8, 9, 12, 15) and on the day of the clinic visit at Weeks 16, 17, 18, 20, 23, and 27. The Week 5, 8, and 12 post-dose (PK sampling was performed within 6 days of drug administration. EC50 estimates used PK data as well as HbA1c and FPG efficacy data. EC50 was estimated from an inhibitory Emax (maximal possible effect of albiglutide) model.
