| Outcome Measures: |
Primary: Safety and pharmacokinetics of multiple-dose oral administration of S-707106 in fed state in patients with type 2 diabetes mellitus, Safety will be evaluated by monitoring of treatment-emergent adverse events, clinical laboratory evaluations, vital signs, 12-lead electrocardiograms, 24-hour telemetry monitoring and physical exams. Pharmacokinetic evaluation of monotherapy cohort versus add-on therapy will be done, Adverse events will be monitored from the time of informed consent through 28 days after the last dose of study treatment. Samples for S-707106 will be collected on Days 1, 7, 10, 12, 13, and 14|Safety and pharmacokinetics of multiple-dose oral co-administration of S-707106 and metformin in fed state in patients with type 2 diabetes mellitus, Safety will be evaluated by monitoring of treatment-emergent adverse events, clinical laboratory evaluations, vital signs, 12-lead electrocardiograms, 24-hour telemetry monitoring and physical exams.
