Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study evaluated the efficacy and safety of canagliflozin in Asian participants with type 2 diabetes mellitus who had inadequate glycemic control on a maximally effective or tolerated dose of metformin alone or metformin plus sulphonylurea (SU). It was conducted between 30 June 2011 and 21 December 2012 and recruited patients from 36 sites.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The study had two background treatment strata: 331 participants in the metformin alone stratum and 347 in the metformin plus SU. In total, 678 participants were randomly allocated to the 3 treatment arms, 676 received at least 1 dose of study drug and were included in the modified intent-to-treat (mITT) analysis set and the safety analysis set.
