Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase IIb, Randomized, Double-Blind, Placebo-Controlled, Active Controlled, Parallel Group, Multicenter Study to Assess the Safety and Efficacy of 2 Fixed Dose Groups of TC-5214 (S-mecamylamine) as Monotherapy Treatment in Patients With Major Depressive Disorder Who Exhibit an Inadequate Response to Antidepressant Therapy

Primary Outcome Measures:
  • Change in the Montgomery Asberg Depression Rating Scale (MADRS) Total Score From Randomization to End of Treatment [ Time Frame: Randomization (Week 8) to end of treatment (Week 16) ]
    A 10-item scale for the evaluation of depressive symptoms. Each Montgomery Asberg Depression Rating Scale (MADRS) item is rated on a 0 to 6 scale. The MADRS total score is calculated as the sum of the 10 individual item scores; the total score can range from 0 to 60. Higher MADRS scores indicate higher levels of depressive symptoms.
