The purpose of this study is to assess the pharmacokinetics (ie, how the body affects the drug) and pharmacodynamics (ie, how the drug affects the body) of increasing doses of canagliflozin (JNJ-28431754) in healthy obese volunteers.
This study will be a single-center, randomized (the treatment is assigned by chance), double-blind (neither investigator nor volunteer knows the identity of the assigned treatment), placebo-controlled (one of the study medications is inactive), ascending multiple dose study (increasing doses of study medication) to assess the pharmacokinetics and pharmacodynamics of canagliflozin (a drug currently being investigated for the treatment of type 2 diabetes mellitus) in otherwise healthy obese volunteers. The study will consist of 3 phases: a screening phase, a double-blind treatment phase, and an end of study (or follow-up) phase. Volunteers will be assigned to 5 cohorts (groups) made up of 16 otherwise healthy obese men and women. Within each group, 12 volunteers will be given canagliflozin once or twice daily and 4 volunteers will be given placebo (inactive medication) once or twice daily for 14 days. The dose of canagliflozin will be different for each of the 5 groups and the second group will not begin treatment until at least 21 days after the first group start treatment. This 21-day gap will be applied to all subsequent groups. Each volunteer will participate in the study for approximately 58 days.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Canagliflozin (JNJ-28431754) | Drug | A 30mg/day, 100 mg/day, 300 mg/day, or 600 mg/day liquid dose administered once daily; a 300mg/day liquid dose administered in 2 divided doses (2x150 mg); or a 600 mg/day liquid dose administered in 2 divided doses (2x300 mg) using an oral (by mouth) liquid dispenser on Days 1 through 14. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in urine glucose excretion per day | The change from baseline in urine excretion per day will be compared following escalating doses of canagliflozin (JNJ-28431754). | Day -1 (Baseline) up to Day 17 |
| Change from baseline in urine glucose excretion per hour | The change from baseline in urine excretion per hour will be compared following escalating doses of canagliflozin (JNJ-28431754). | Day -1 (Baseline) up to Day 17 |
| Visual analog scale (VAS) scores related to hunger, satiety, fullness and prospective food consumption | Visual analog scale (VAS) scores will be obtained from the VAS questionnaire. In the VAS questionnaire, volunteers mark a point on a line (drawn between 2 statements) to indicate how they feel about the statements. The statements about hunger are as follows: "I am not hungry at all" and "I have never been hungrier". Other statements relate to satiety (feeling satisfied), feeling full and prospective food consumption. Scores will be compared following escalating doses of canagliflozin (JNJ-28431754). | Day -2 up to Day 17 |
| Change from baseline in mean 24-hour plasma glucose concentrations | The change from baseline in mean 24-hour plasma glucose concentrations will be compared following escalating doses of canagliflozin (JNJ-28431754). | Day -1 (Baseline) up to Day 16 |
| Measure | Description | Time Frame |
|---|---|---|
| Renal threshold for glucose excretion | The point at which glucose starts to appear in the urine is known as the renal threshold. The way in which the renal threshold varies in relation to the dose of canagliflozin (JNJ-28431754) will be calculated. | Up to Day 17 |
| Change from baseline in mean 24-hour plasma insulin concentrations |
