HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total score of 50. Change= 8 week adjusted mean HAM-D17 minus baseline adjusted mean HAM-D17

Double-blind phase; modified intent to treat population, which included all randomized patients with a baseline HAM-D17 score ≥18, who took ≥1 dose of study drug and had ≥1 post-baseline HAM-D17 evaluation. Mixed model repeated measures (MMRM) modeling included all available observed data for each patient and no missing values were imputed.

CGI-I is a global rating scale that measures disease improvement. Using a 7-point scale, the clinician rates how much the patient's illness has improved or worsened relative to the baseline status (1= very much improved; 7= very much worse).

The HAM-A is a standardized, clinician-administered rating scale that assesses 14 items characteristically associated with major anxiety disorders. Items are scaled 0 - 4 (0=none and 4=very severe), with a maximum total score of 56. Change= 8 week adjusted mean HAM-A score minus baseline adjusted mean score.

Double-blind phase; modified intent to treat population, which included all randomized patients with a baseline HAM-D17 score ≥18, took ≥1 dose of study drug and had ≥1 post-baseline HAM-D17 evaluation. Mixed model repeated measures (MMRM) modeling included all available observed data for each patient and no missing values were imputed.

EQ-5D is a standardized, subject-administered measure of health outcome. It provides a descriptive profile for 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), using 3 levels (no, moderate, or extreme problems) and a single index value characterizing current health status using a 100-point visual analog scale (0=worst, 100=best). EQ-5D summary index is obtained with a formula that weights each level of the dimensions. The index-based score is interpreted along a continuum of 0 (death) to 1 (perfect health). Change=8 week score minus baseline score.

HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total s core of 50. Change= Final Evaluation mean HAM-D17 minus baseline mean HAM-D17.

Open-label phase safety population: All patients who completed the double-blind phase, elected to continue treatment in the open-label phase, and received at least 1 dose of study drug in the open-label phase. One patient did not have a baseline and at least 1 on therapy assessment.

DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom," "absent," or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.

Open-label (OL) safety population: Patients completed double-blind and continued in OL with ≥1 dose study drug. Excluded patients lost to follow-up and discontinued with <4 wks therapy. Patients analyzed varied by time (0mg, 100mg, 200mg): Early Termination (n=9,98,207); Taper week 1 (n=4,76,193); Taper week 2 (n=5,75,195); Post-taper (n=5,71,192)
