  Purpose

The purpose of this study is to evaluate the efficacy and safety of 2 different doses of canagliflozin compared with placebo in patients with type 2 diabetes mellitus who are receiving treatment with metformin monotherapy (ie, treatment with a single drug) and have inadequate glycemic (blood sugar) control.

Primary Outcome Measures:
  • Change in HbA1c From Baseline to Week 18 [ Time Frame: Day 1 (Baseline) and Week 18 ] [ Designated as safety issue: No ]
    The table below shows the least-squares (LS) mean change in HbA1c from Baseline to Week 18 for each treatment group. The statistical analyses show the treatment differences (ie, each canagliflozin group minus placebo) in the LS mean change.


Secondary Outcome Measures:
  • Change in Fasting Plasma Glucose (FPG) From Baseline to Week 18 [ Time Frame: Day 1 (Baseline) and Week 18 ] [ Designated as safety issue: No ]
    The table below shows the least-squares (LS) mean change in FPG from Baseline to Week 18 for each treatment group. The statistical analyses show the treatment differences (ie, each canagliflozin group minus placebo) in the LS mean change.

  • Percent Change in Body Weight From Baseline to Week 18 [ Time Frame: Day 1 (Baseline) and Week 18 ] [ Designated as safety issue: No ]
    The table below shows the least-squares (LS) mean percent change in body weight from Baseline to Week 18 for each treatment group. The statistical analyses show the treatment differences (ie, each canagliflozin group minus placebo) in the LS mean percent change.

  • Percentage of Patients With HbA1c <7% at Week 18 [ Time Frame: Week 18 ] [ Designated as safety issue: No ]
    The table below shows the percentage of patients with HbA1c <7% at Week 18 in each treatment group. The statistical analyses show the treatment differences (ie, each canagliflozin group minus placebo) in the percentage.

Study Start Date: July 2011
Study Completion Date: April 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Canagliflozin 50 mg bid
Each patient will receive 50 mg canagliflozin twice daily for 18 weeks.
Drug: Canagliflozin 50 mg
One canagliflozin 50-mg capsule taken orally twice daily with a meal for 18 weeks
Drug: Metformin
The patient's stable daily dose of Metformin background therapy should be continued throughout the study.
Experimental: Canagliflozin 150 mg bid
Each patient will receive 150 mg canagliflozin twice daily for 18 weeks
Drug: Canagliflozin 150 mg
1 canagliflozin 150-mg capsule taken orally twice daily with a meal for 18 weeks
Drug: Metformin
The patient's stable daily dose of Metformin background therapy should be continued throughout the study.
Placebo Comparator: Placebo
Each patient will receive matching placebo twice daily for 18 weeks
Drug: Placebo
1 placebo capsule taken orally twice daily with a meal for 18 weeks
Drug: Metformin
The patient's stable daily dose of Metformin background therapy should be continued throughout the study.

Detailed Description:

This is a randomized (study drug assigned by chance), double-blind (neither the patient nor the study doctor will know the identity of assigned study drug), placebo-controlled, parallel-group,3-arm (3 treatment groups) multicenter study to determine the efficacy, safety, and tolerability of canagliflozin compared to placebo (a capsule that is identical in appearance to canagliflozin but does not contain active drug) in patients with type 2 diabetes mellitus (T2DM) who are not achieving an adequate response from current antihyperglycemic therapy with metformin to control their diabetes. Canagliflozin (a Sodium-Glucose Cotransporter 2 inhibitor) is currently under development to lower blood sugar levels in patients with T2DM. Patients will take single-blind placebo capsules orally (by mouth) for 2 weeks before randomization. Patients will be randomly assigned canagliflozin or matching placebo, orally, twice daily, with 1 capsule taken with the morning meal and 1 capsule taken with the evening meal (2 capsules per day) and concurrent with metformin, if applicable, for up to 18 weeks. The dosing time of metformin should remain the same throughout the study.
