Safety and Effectiveness Study of BCI-540 Versus Placebo in the Treatment of Major Depressive Disorder With Concomitant Anxiety
A 6-Week Randomised Double-Blind, Placebo-Controlled Study of BCI-540 80 mg q.d. and 80 mg t.i.d. in the Treatment of Adults With Major Depressive Disorder and Concomitant Anxiety
The purpose of this study is to determine whether BCI-540 80 mg given once daily (q.d.) or three times daily (t.i.d.) is effective in the treatment of major depression with concomitant anxiety.
BCI-540 has been shown to be neurogenic in the Sponsor's in vitro neural stem cell analyses and in vivo animal models of depression and anxiety. These observations and the recent findings linking hippocampal function and neurogenesis to mood disorders support the evaluation of the efficacy, safety, and tolerability of BCI-540 in patients with major depressive disorder with concomitant anxiety.

Exclusion Criteria: The patient has a decrease of 20% or more in HAM D17 total score or HAM-A total score from the screening visit to the Baseline visit. The patient represents significant risk of suicide in the opinion of the investigator at the screening or Baseline visit. The patient has any other psychiatric Axis-I disorder (except GAD) as a principal diagnosis within 6 months of Screening. The patient has a history of obsessive compulsive disorder, psychotic disorder, bipolar disorder, mental retardation.
