Participant Flow

Patient with major depression who do not have a serious, unstable medical illness and are 21 to 55 years of age may be eligible. Candidates are screened with a psychiatric and medical history, diagnostic interview, physical examination, electrocardiogram, blood tests and, for women, a pregnancy test.

Participants are tapered off anti-depression drugs (and any other medications not allowed) over a 3-week period and then begin a 2-week drug-free period. During these 2 weeks they have an electroencephalogram (EEG) with light stimulation, and those whose EEG indicates a seizure disorder are excluded from the study.

Blinded, active experimental compound. Dosing starts at 250 mg once per day for one week, then 250 mg twice per day for one week, then 500 mg twice per day. After 4 weeks with insufficient response, the dose may be increased to 750 mg twice per day. The titration schedule may be delayed if the subject is experiencing adverse effects. The subject may be increased or decreased at the discretion of the investigator. The minimum dose allowed for the study is 250 mg once per day.
Placebo
Blinded placebo. Dosing starts at 250 mg once per day for one week, then 250 mg twice per day for one week, then 500 mg twice per day. After 4 weeks with insufficient response, the dose may be increased to 750 mg twice per day. The titration schedule may be delayed if the subject is experiencing adverse effects. The subject may be increased or decreased at the discretion of the investigator. The minimum dose allowed for the study is 250 mg once per day.
