NCT ID: NCT00692445 Completed - Depression Clinical Trials

TC-5214 as add-on the Treatment of Major Depressive Disorder

Start date: June 2008
Phase: Phase 2
Study type: Interventional

This is a multi-center, double blind, randomized, placebo-controlled, parallel group, flexible dose titration study conducted in centers in the USA and India. Following a washout period, subject will be treated with citalopram 20 mg once daily for 4 weeks, then with 40 mg once daily for 4 weeks. Subjects who tolerate 40 mg citalopram, but whose MADRS score is < 50% from baseline, but no lower than 17, will be considered partial or non-responders and will be randomized to receive either placebo or TC-5214 as add-on therapy. TC-5214 or placebo will be started at 2 mg daily (BID dosing), and be titrated based on tolerability and therapeutic response up to 8 mg daily. Approximately 560 subjects will enter the Open Label Phase and approximately 220 will enter the double blind phase of the study.
