Trial Outcomes & Findings for A Phase III Study of BMS-512148 (Dapagliflozin) in Asian Patients With Type 2 Diabetes Who Are Not Well Controlled on Metformin Alone (NCT NCT01095666)

NCT ID: NCT01095666

Last Updated: 2017-09-11

Results Overview

HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 4, 8, 12, 16, 20, and 24 in the double-blind period.

PRIMARY outcome

Timeframe: From Baseline to Week 24

Population: All randomized participants who received study medication and had nonmissing HbA1c values at baseline and Week 24 (LOCF)

HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 4, 8, 12, 16, 20, and 24 in the double-blind period.

SECONDARY outcome

Timeframe: From Baseline to Week 24

Population: All randomized participants who received study medication and had nonmissing FPG values at baseline and Week 24 (LOCF)

Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Fasting plasma glucose was measured as milligrams per deciliter(mg/dL) by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. FPG measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 1, 2, 4, 8, 12, 16, 20, and 24 in the double-blind period.

SECONDARY outcome

Timeframe: From Baseline to Week 24

Population: All randomized participants who received study medication and had nonmissing body weight values at baseline and Week 24 (LOCF)

Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Adjusted mean change from baseline in total body weight at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.

Population: All randomized participants who received study medication and had nonmissing HbA1C values at Week 24 (LOCF)

Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Therapeutic glycemic response is defined as HbA1c \<7.0%. Data after rescue medication was excluded from this analysis. HbA1c was measured as a percent of hemoglobin. Percentage of participants were estimated by modified logistic regression model, adjusted for baseline HbA1c.
