Trial Outcomes & Findings for A Randomised, db, Placebo-controlled Study of BI 1356 for 18 Weeks Followed by a 34 Week Double-blind Extension Period (Placebo Patients Switched to Glimepiride) in Type 2 Diabetic Patients for Whom Treatment With Metformin is Inappropriate (NCT NCT00740051)

NCT ID: NCT00740051

Last Updated: 2014-06-27

Results Overview

HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 18 HbA1c percent minus the Week 0 HbA1c percent. Means are adjusted for baseline HbA1c, prior OADs and reason for metformin intolerance.

PRIMARY outcome

Timeframe: Baseline and week 18

Population: The Full Analysis Set (FAS) included all treated patients with a baseline and at least one on-treatment HbA1c measurement available during the first phase of the study. Last Observation Carried Forward (LOCF) was used as the imputation rule.

HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 18 HbA1c percent minus the Week 0 HbA1c percent. Means are adjusted for baseline HbA1c, prior OADs and reason for metformin intolerance.
