Trial Outcomes & Findings for MK0431/ONO-5435 Phase III Clinical Trial -Add-on to Voglibose Study for Patients With Type 2 Diabetes Mellitus (MK0431-104) (NCT NCT00837577)

NCT ID: NCT00837577

Last Updated: 2017-05-15

Results Overview

Change from baseline measurement, where the baseline measurement was obtained at randomization (Week 0) before receiving study medication. This study used Japan Diabetes Society (JDS)-certified HbA1c values, the standard at the time when the study was conducted (HbA1c \[National Glycohemoglobin Standardization Program; NGSP\] = HbA1c (JDS-HbA1c \[%\]) + 0.4%).
