Subjects with MDD:

In addition to inclusion criteria mentioned above for healthy subjects, the following inclusion criteria will be applied to subjects with MDD:

Have the diagnosis of MDD as defined by the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition; Text Revision (DSM IV TR) criteria and confirmed by the Mini International Neuropsychiatric Interview (MINI) diagnostic interview. This diagnosis will be confirmed by a psychiatrist or psychologist. The diagnosis should be supplemented (when possible) by confirmation of chart records or by a discussion with a treating healthcare professional or reliable informant. Diagnosis made by a psychologist must be reviewed by a psychiatrist.

The subjects' current major depressive episode must be ≥ 4 weeks and < 2 years in duration.

Are able to wash-out from prior antidepressant therapies by Day -1, are able to forego psychotherapy from Day -1 through Day 10, inclusive, and are deemed clinically stable by PI's assessment.

May have a comorbid anxiety disorder such as generalized anxiety disorder (GAD) or social phobia but not obsessive compulsive disorder (OCD) as long as the comorbid anxiety disorder is not the major source of impairment.

Have a stable living arrangement for at least 3 months prior to check in and agree to return to a similar living arrangement after discharge. This criterion is not meant to exclude subjects who have temporarily left a stable living environment. Such subjects remain eligible to participate in this study. Chronically homeless subjects should not be enrolled. The Medical Monitor should be consulted for individual cases as needed.

Exclusion Criteria:

Healthy Subjects

Significant history or clinical manifestations of any acute or chronic condition that in the opinion of the PI, would limit the subject's ability to complete and/or participate in the study:

metabolic, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, urological, neurological, or psychiatric disorders; drug hypersensitivity; stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (appendectomy, hernia repair, and/or cholecystectomy will be allowed at the discretion of the PI); abnormal ECG, which, in the PI's opinion, is clinically significant; known or suspected alcohol or substance abuse/ dependence within one year prior to check in; movement disorders including tremor; lifetime or family history of seizures or a febrile seizure.

Subjects with MDD

Except for Exclusion Criterion 18 mentioned above for healthy subjects all exclusion criteria will be applied and in addition the following exclusion criteria will be applied to subjects with MDD:

History of bipolar disorder (I or II), schizophrenia, schizoaffective disorder, eating disorder, or obsessive compulsive disorder.
