A Multicenter, Relapse Prevention Study With Levomilnacipran Extended Release (ER) in Participants With Major Depressive Disorder

Time to First Relapse During the Double-Blind Treatment Period (DBTP)

Time to relapse for the median was measured in days from randomization date at the start of the DBTP to relapse date during DBTP. Relapse was defined as meeting any 1 or more of the following criteria: 1) Insufficient therapeutic response at any one visit, including a \>/= 2 increase in Clinical Global Impressions-Severity (CGI-S) score (range 1 to 7) compared with that obtained at randomization, or risk of suicide as determined by the investigator, or need for hospitalization due to worsening of depression as determined by the investigator, or need for alternative treatment of depressive symptoms as determined by the Investigator; 2) Montgomery-Asberg Depression Rating Scale (MADRS) total score \>/= 18 (range 0 to 60) at 2 consecutive visits (second visit within 7 to 14 days after the first visit at which the MADRS total score was ≥ 18). Participant was considered censored at the last visit during DBTP if participant did not meet the relapse criteria during DBTP.

Time frame: From the randomization date (Week 20) to the relapse date during the 26-week DBTP (up to Week 46)
