What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| safety and tolerability assessed by incidence and severity of AE's, abnormalities in vital sign assessments, ECG's, telemetry, clinical lab assessments, physical exams, neurological exams, suicidality evaluations, visual acuity tests and digital ECGs |  | Collected prior to treatment, during treatment and for 7-10 days following discharge. Volunteers will be monitored througout the study for adverse events. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To characterize the pharmacokinetics of TC-5214 in blood and urine after single and repeated oral doses by collecting blood and urine samples to measure drug concentration levels |  | Blood sampling, every in house day; urine collection ;Days -1 through Day 6, Days 8 through 11. | 
| To assess the effect of food on the pharmacokinetics of TC-5214 following oral administration by collecting blood and urine samples to measure drug concentration levels. |  | Samples taken during the residential period at defined timepoints pre-dose and post-dose |
