Clinical Trial Summary

This study is looking at the efficacy, rapidity, safety, and tolerability of two doses of oral CERC-501 for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.

Description:

This study will involve 10 visits to the clinical site over approximately 1.5 months. There will be a screening visit (7-28 days may pass between the screening visit and the first treatment visit), a baseline/treatment visit (first day of study drug treatment), followed by 5 consecutive days of treatment visits. Follow-up visits will occur 6, 13, and 20 days after first receiving study drug.
