The participant is, in the opinion of the investigator, not able to complete the neuropsychological tests validly at the Baseline Visit.~8. If female, the participant is pregnant or lactating or intending to become pregnant before, during, or within 30 days after participating in this study; or intending to donate ova during such time period.~9. The participant has 1 or more of the following:~   1. Any current psychiatric disorder other than MDD as defined in the DSM-IV-TR (as assessed by the MINI Version 6.0.0).~  2. Current or history of attention deficit hyperactivity disorder (ADHD), pervasive developmental disorder, manic or hypomanic episode, schizophrenia, or any other psychotic disorder, including major depression with psychotic features, mental retardation, organic mental disorders, or mental disorders due to a general medical condition as defined in the DSM-IV-TR.~  3. Current diagnosis of alcohol or other substance abuse or dependence (excluding nicotine or caffeine) as defined in the DSM-IV-TR that has not been in sustained full remission for at least 2 years prior to Screening. (Participant must also have negative urine drug screen prior to Baseline).~  4. Presence or history of a clinically significant neurological disorder (including epilepsy).~  5. Neurodegenerative disorder (Alzheimer's disease, Parkinson's disease, multiple sclerosis, Huntington's disease, etc).~  6. Any DSM-IV Axis II disorder that might compromise the study.~10.

The participant is diagnosed with reading disability (dyslexia).~13. The participant has a significant risk of suicide according to the investigator's clinical judgment or has a score ≥5 on item 10 (suicidal thoughts) of the MADRS or has made a suicide attempt in the previous 6 months.~14.

The participant has initiated formal cognitive or behavioral therapy, systemic psychotherapy within less than 6 months of study screening, or has plans to initiate such therapy during the study.~16. The participant has received electroconvulsive therapy, vagal nerve stimulation, or repetitive transcranial magnetic stimulation within 6 months prior to Screening.~17. The current depressive symptoms are considered by the investigator to have been resistant to 2 adequate antidepressant treatments of at least 6 weeks duration each at the recommended dose.~18.

The participant has a known history of or currently has increased intraocular pressure or is at risk of acute narrow-angle glaucoma.~22.

The participant has clinically significant abnormal vital signs as determined by the investigator.~25. The subject has thyroid stimulating hormone (TSH) outside the normal range at the Screening Visit.~    Note: If TSH value is outside the normal range, a free T4 will be obtained. Subjects who have elevated TSH but normal T4 (i.e. subclinical hypothyroidism) will be excluded. For subjects who are on thyroid hormone replacement therapy, a lower TSH with normal T4, are eligible to participate in the study only if there are no clinical symptoms of hypothyroidism .~26. The participant has 1 or more laboratory value outside the normal range, based on the blood or urine samples taken at the Screening Visit, that are considered by the investigator to be clinically significant; or the participant has any of the following values at the Screening Visit:~    1. A serum creatinine value \>1.5 times the upper limits of normal (×ULN).~   2. A total serum total bilirubin value \>1.5×ULN.~   3. A serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) value \>2×ULN.~27.
