Major depressive disorder

Brief summary

Mean change from baseline (visit 2) in symptom severity as measured by the MADRS total score at six weeks (visit 4) will be compared between the two treatment arms (EIPT vs. TAU).

Detailed description

1.a. Change from baseline (visit 2) in the severity sub-score of the Clinical Global Impression Scale (CGI) at visit 4; EIPT vs TAU. 1.b. Improvement sub-score of the Clinical Global Impression Scale (CGI) at visit 4; EIPT vs TAU., Changes from baseline (visit 2) in total Hospital Anxiety and Depression Scale (HADS) total score and anxiety and depression subscales at visit 4; EIPT vs TAU., Change from baseline (visit 2) in quality of life and functioning measures (Q-LES-Q-SF, LAPS, QLS-100 and SDS ) at visit 4; EIPT vs TAU., Changes from baseline (visit 2) on Trail Making Test, Digit Symbol Substitution Test, Rey Auditory Verbal Learning Test as well as the Perceived Deficits Questionnaire at visit 4; EIPT vs TAU., Presence of symptomatic remission at visit 4; EIPT vs TAU. Remission is defined as a MADRS score ≤ 12., Presence of reported side effects as measured through General Assessment of Side Effects Scale (GASE) and reported spontaneously throughout the studyat visit 4; EIPT vs TAU., Concomitant medication use throughout the studyat visit 4; EIPT vs TAU., Premature treatment discontinuation before visit 4 and time to treatment discontinuation and reported reason of discontinuation; EIPT vs TAU., Changes on the Columbia-Suicide Severity Rating Scale (C-SSRS) throughout the study; EIPT vs TAU
