Healthy volunteers: no

Brief summary:
The purpose of this study is to assess the safety, tolerability, and efficacy of the addition of canagliflozin relative to the addition of placebo in patients with inadequate glycemic control on metformin alone or in combination with a sulphonylurea.

Detailed description:
This is a double-blind (neither study staff or the patient will know the identity of the treatment assigned) study of canagliflozin where Chinese and other Asian adult patients with Type 2 Diabetes Mellitus (T2DM) who have inadequate glycemic control on metformin alone or in combination with a sulphonylurea (SU) will be randomized (assigned to 1 of 3 treatments by chance) to receive the addition of treatment with canagliflozin 100 mg once daily, canagliflozin 300 mg once daily, or matching placebo capsules (placebo is a treatment identical in appearance to canagliflozin but does not contain active drug). All patients will take orally (by mouth) 1 single-blind placebo capsule once daily before the first meal of the day for up to 2 weeks (last dose of single-blind placebo to be taken the day before the baseline (Day 1) visit. On Day 1, patients will take orally, once daily 1 capsule of canagliflozin 100 mg, canagliflozin 300 mg, or placebo before the first meal of the day for up to 18 weeks.

Arms:
arm 1: Each participant will receive 100 mg of canagliflozin once daily for 18 weeks with protocol-specified doses of metformin alone or metformin plus sulphonylurea. arm 2: Each participant will receive 300 mg of canagliflozin once daily for 18 weeks with protocol-specified doses of metformin alone or metformin plus sulphonylurea. arm 3: Each participant will receive matching placebo once daily for 18 weeks with protocol-specified doses of metformin alone or metformin plus sulphonylurea.

Interventions: intervention 1: Placebo intervention 2: Canagliflozin 100mg intervention 3: Canagliflozin 300mg intervention 4: Metformin intervention 5: Sulphonylurea
Intervention descriptions: intervention 1: Form=capsule, route=oral administration. One capsule once daily for up to 18 weeks after completing a single-blind placebo run-in period (1 placebo capsule once daily for up to 2 weeks). intervention 2: Type=1, unit=mg, number=100, form=capsule, route=oral use. One capsule once daily for up to 18 weeks after completing a single-blind placebo run-in period (1 placebo capsule once daily for up to 2 weeks). intervention 3: Type=1, unit=mg, number=300, form=capsule, route=oral use. One capsule once daily for up to 18 weeks after completing a single-blind placebo run-in period (1 placebo capsule once daily for up to 2 weeks). intervention 4: The participant's stable dose of background therapy of metformin should be continued throughout the study. intervention 5: The participant's stable dose of background therapy of metformin plus sulphonylurea should be continued throughout the study.
