Study summary

What the protocol is testing.

This randomized, double-blind, active-controlled study evaluates the efficacy and safety of a weekly dose of albiglutide as compared with sitagliptin. Subjects who are renally impaired with a historical diagnosis of type 2 diabetes mellitus and whose glycemia is inadequately controlled on their current regimen of diet and exercise or their antidiabetic therapy of metformin, thiazolidinedione, sulfonylurea, or any combination of these oral antidiabetic medications will be recruited into the study.

Outcomes

What the study measures.

Primary outcomes

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 26

Time frame · Baseline; Week 26

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 value at Week 26 minus the value at Baseline. The analysis was performed using an Analysis of Covariance (ANCOVA) model with treatment group, region, history of prior myocardial infarction (yes versus no), and age category (\<65 years versus \>=65 years) as factors and Baseline HbA1c as a continuous covariate. The last observation carried forward (LOCF) method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing.

Secondary outcomes

Mean Change From Baseline in HbA1c at Weeks 4, 8, 12, 16, and 20: LOCF

Time frame · Baseline; Weeks 4, 8, 12, 16, and 20

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 Baseline value. The LOCF method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing. Participants were analyzed in a particular treatment week if they had received at least one dose in that treatment week.

Mean Change From Baseline in HbA1c at Weeks 4, 8, 12, 16, 20, 26, 36, 48, and Week 52: Observed Cases

Time frame · Baseline; Weeks 4, 8, 12, 16, 20, 26, 36, 48, and 52

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 Baseline value. The Observed Cases (OC) method (no imputation of missing data) was used. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing. Participants were analyzed in a particular treatment week if they had received at least one dose in that treatment week.

Change From Baseline in Fasting Plasma Glucose (FPG) at Week 26

Time frame · Baseline; Week 26

The FPG test measures blood sugar levels after the participant has not eaten (fasted) for 12 to 14 hours. The Baseline FPG value is define as the last non-missing value before the start of treatment. Change from Baseline in FBG was calculated as the post-Baseline value minus the Baseline value. The LOCF method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing. Participants were analyzed in a particular treatment week if they had received at least one dose in that treatment week. Based on ANCOVA: Change = treatment + Baseline FPG + renal impairment + prior myocardial infarction history + age category + region.

Mean Change From Baseline in FPG at Weeks 4, 8, 12, 16, 20, and 26: LOCF

Time frame · Baseline; Weeks 4, 8, 12, 16, 20, and 26

The FPG test measures blood sugar levels after the participant has not eaten (fasted) for 12 to 14 hours. The Baseline FPG value is the last non-missing value before the start of treatment. Change from Baseline in FBG was calculated as the post-Baseline value minus the Baseline value. The LOCF method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing. Participants were analyzed in a particular treatment week if they had received at least one dose in that treatment week.

Mean Change From Baseline in Fasting Plasma Glucose (FPG) at Weeks 1, 2, 3, 4, 8, 12, 16, 20, 26, 36, 48, and Week 52: OC

Time frame · Baseline; Weeks 1, 2, 3, 4, 8, 12, 16, 20, 26, 36, 48, Week 52

The FPG test measures blood sugar levels after the participant has not eaten (fasted) for 12 to 14 hours. The Baseline FPG value is defined as the last non-missing value prior to treatment. Change from Baseline in FBG was calculated as the post-Baseline value minus the Baseline value. The OC method (no imputation of missing data) was used. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing. Participants were analyzed in a particular treatment week if they had received at least one dose in that treatment week.

Number of Participants Who Achieved Clinically Meaningful HbA1c Response Levels of <6.5% and <7.0% at Week 26: LOCF

Time frame · Week 26

The number of participants who acheieved the HbA1c treatment goal (i.e., the number of participants who achieved HbA1c \<7% and \<6.5% at Week 26) was assessed. The LOCF method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement. If a participant had missing observation(s) immediately after Baseline, the Baseline observation was not carried forward and was left as missing.

Number of Participants Who Achieved a Clinically Meaningful Improvement in the HbA1c Response Level of >=1.0%, >=1.5%, and >=2.0% at Week 26: LOCF

Time frame · Week 26

The number of participants who a clinically meaningful improvement from Baseline in the HbA1c response level of \>=1.0%, \>=1.5%, and \>=2.0% at Week 26 were assessed. The LOCF method was used to impute missing data, in which the last non-missing post-Baseline on-treatment measurement was used to impute the missing measurement.

Number of Participants With the Indicated Time to Hyperglycemic Rescue Through Week 52

Time frame · Week 2 to Week 52

Hyperglycemic rescue was defined as meeting one of the following criteria, confirmed by a second sample drawn within 7 days and analyzed by the central laboratory: for the Week 2 to Week 4 visit, a single FPG value \>=280 milligrams per deciliter (mg/dL); for the \>Week 4 and \<Week 12 visits, a single FPG value \>=250 mg/dL and previous titration for \>=4 weeks; for the \>=Week 12 and \<Week 26 visits, HbA1c \>=8.5% and a \<=0.5% reduction from Baseline and previous titration for \>=4 weeks; for the \>=Week 26 and \<Week 48 visits, HbA1c \>=8.5% and previous titration for \>=4 weeks; for the \>=Week 48 and \<Week 52 visits, HbA1c \>=8.0% and previous titration for \>=4 weeks. Time to hyperglycemia rescue is the time between the date of first dose and the date of hyperglycemia rescue plus 1 day, or the time between the date of first dose and the date of last visit during active treatment period plus 1 day for participants not requiring rescue.
