Brief summary:
This is a multicenter, 52-week, open-label study designed to assess the safety and tolerability of an oral aripiprazole/escitalopram combination therapy in outpatients with major depressive disorder (MDD). Enrollment into the study will be from eligible participants who have completed participation in Protocol 31-08-255 \[NCT01111539\], 31-08-256 \[NCT01111552\], or 31-08-263 \[NCT01111565\] ("rollover" participants).

Detailed description:

Arms: arm 1: Aripiprazole capsules, orally at the daily dose of 3, 6, or 12 mg, in combination with escitalopram 10 or 20 mg orally, once daily in combination with escitalopram 10 or 20 mg (i.e., the final dose taken during the previous study), orally, once daily, for 36 weeks. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 1 if the initial 6 mg/day dose was tolerated. The dose adjustments were allowed for aripiprazole to establish the maximum tolerated dose (MTD) by Week 4. Participants who received aripiprazole/escitalopram combination therapy in the double-blind treatment period in previous studies were included in this group. arm 2: Aripiprazole capsules, orally at the daily dose of 3, 6, or 12 mg, in combination with escitalopram 10 or 20 mg orally, once daily in combination with escitalopram 10 or 20 mg (i.e., the final dose taken during the previous study), orally, once daily, for 36 weeks. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 1 if the initial 6 mg/day dose was tolerated. The dose adjustments were allowed for aripiprazole to establish the MTD by Week 4. Participants who received escitalopram in the double-blind treatment period in previous studies were included in this group. arm 3: Aripiprazole capsules, orally at the daily dose of 3, 6, or 12 mg, in combination with escitalopram 10 or 20 mg orally, once daily in combination with escitalopram 10 or 20 mg (i.e., the final dose taken during the previous study), orally, once daily, for 36 weeks. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 1 if the initial 6 mg/day dose was tolerated. The dose adjustments were allowed for aripiprazole to establish the MTD by Week 4. Participants who received aripiprazole in the double-blind treatment period in previous studies were included in this group. arm 4: Aripiprazole capsules, orally at the daily dose of 3, 6, or 12 mg, in combination with escitalopram 10 or 20 mg orally, once daily in combination with escitalopram 10 or 20 mg (i.e., the final dose taken during the previous study), orally, once daily, for 36 weeks. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 1 if the initial 6 mg/day dose was tolerated. The dose adjustments were allowed for aripiprazole to establish the MTD by Week 4. Participants who received escitalopram in the single-blind treatment period in previous studies were included in this group.
