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 compared with sitagliptin and placebo in patients with type 2 diabetes mellitus with inadequate control despite treatment with metformin. The study was conducted between 07 April 2010 and 17 August 2012 and recruited patients from 169 study centers in 22 countries worldwide.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
1,284 patients were randomly allocated to the 4 treatment arms. All patients received at least 1 dose of study drug and were included in the modified intent-to-treat (mITT) analysis set (used for the Week 26 and week 52 efficacy analyses). All 1,284 patients were included in the Week 26 and Week 52 safety analysis sets.

Reporting Groups
  Description
Placebo/Sitagliptin Each patient received matching placebo once daily for 26 weeks and were then switched from placebo to 100 mg of sitagliptin once daily until Week 52. Placebo and sitagliptin were given with protocol-specified doses of metformin immediate release.
Canagliflozin 100 mg Each patient received 100 mg of canagliflozin once daily for 52 weeks with protocol-specified doses of metformin immediate release.
Canagliflozin 300 mg Each patient received 300 mg of canagliflozin once daily for 52 weeks with protocol-specified doses of metformin immediate release.
Sitagliptin 100 mg Each patient received 100 mg of sitagliptin once daily for 52 weeks with protocol-specified doses of metformin immediate release.
