Brief summary: The purpose of this study is to assess the effect of canagliflozin (JNJ-28431754) on electrocardiogram results (recordings of the electrical activity of the heart) in healthy volunteers after a single therapeutic dose (300 mg) and a single supra-therapeutic dose (4 times higher \[1,200 mg\] than the anticipated therapeutic dose of 300 mg). The safety and tolerability of canagliflozin will also be assessed.

Detailed description: This study will be a randomized (the treatment is assigned by chance), single-center, double-blind (neither investigator nor volunteer knows the identity of the assigned treatment), double-dummy (a technique for retaining the blinded nature of the study when the treatments do not look identical), placebo-controlled (one of the treatments is inactive), positive-controlled (one of the treatments has a known potential effect on electrocardiogram results), four-way cross-over study (all volunteers will receive each of the 4 treatments but in a different order) to assess the effect of canagliflozin (a drug currently being investigated for the treatment of type 2 diabetes mellitus) on electrocardiogram results in healthy 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 1 of 4 treatment sequence groups (ADBC, DABC, BCDA, or CDAB). The treatment sequence will be decided by randomization. Treatment A will be a single dose of 300 mg of canagliflozin. Treatment B will be a single dose of 1,200 mg of canagliflozin. Treatment C will be a single dose of placebo (inactive medication). Treatment D will be a single dose of 400 mg of moxifloxacin (an antibiotic with known potential to affect electrocardiogram results). Each treatment will be given during a treatment period of 2 days duration; each treatment period will be separated by a washout period (when no medication is given) of 10 to 14 days. Each volunteer will participate in the study for approximately 61 days.

Eligibility criteria: Inclusion Criteria:

* Volunteers must have a body mass index (BMI = weight in kg/height in m2) between 18 and 35 kg/m2 (inclusive) and body weight not less than 50 kg
* Volunteers must have an average of triplicate 12-lead electrocardiogram (ECG) recordings, taken with a maximum of 2 minutes between recordings, consistent with normal cardiac conduction and function, as specified by the protocol
* Volunteers must be non-smokers

Exclusion Criteria:

* History of or currently active illness considered to be clinically significant by the Investigator or any other illness that the Investigator considers should exclude the patient from the study or that could interfere with the interpretation of the study results
* History of additional risk factors for the presence of a family history of Short QT Syndrome, Long QT Syndrome, sudden unexplained death at a young age (\<=40 years), drowning or sudden infant death syndrome in a first degree relative (ie, biological parent, sibling, or child)
