Overview
Brief Summary
This study will evaluate the safety, tolerability and efficacy of RO4917523, in comparison to placebo, in patients with treatment-resistant depression. Following a washout period from existing anti-depressant medication, cohorts of patients will be randomized to receive daily oral RO4917523 at up to five different doses (according to the safety and tolerability observed at the lower doses during the study), or placebo. The anticipated time on study treatment is 10 days (in an inpatient unit), and the target sample size is <100 individuals.
