Description of intervention(s) / exposure
Treatment: Drugs - Escitalopram
Treatment: Drugs - Aripiprazole
Treatment: Drugs - Placebo

Active comparator: Phase B: Single-blind Prospective Treatment Phase - Escitalopram 10 mg capsule, orally, once daily increased to 20 mg/day at the end of Week 1 based upon tolerability profile, plus one matching placebo capsule, for 8 weeks. No dose reductions were allowed after Week 4 and no dose increments were allowed after Week 3. Participants with incomplete response at the end of the Phase B (Week 8) entered Phase C and the rest of the participants continued to Phase B+.

Active comparator: Phase B+: Single-blind Phase B Responders - Participants with response at the end of the Phase B (Week 8) continued treatment with the single-blind escitalopram monotherapy at the dose (10 or 20 mg/day) taken during the final week of Phase B plus one matching placebo capsule, for an additional 6 weeks, in Phase B+.

Active comparator: Phase C: Escitalopram Monotherapy - Participants with incomplete response at Week 8 who were randomized to this arm group received escitalopram monotherapy 10 or 20 mg capsule, orally, once daily, whichever dose was taken during the final week of Phase B plus one matching placebo capsule for 6 weeks, in Phase C. No dose adjustments were allowed for escitalopram monotherapy during Phase C.

Active comparator: Phase C: Aripiprazole Monotherapy - Participants with incomplete response at Week 8 who were randomized to this arm group received aripiprazole 3, 6, or 12 mg capsule, orally, once daily plus one matching placebo capsule for 6 weeks, in Phase C. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 9 if the initial 6 mg/day dose was tolerated. No dose increments were allowed after Week 12; however, doses may have been decreased at any week, based upon tolerability.

Active comparator: Phase C: Aripiprazole/Escitalopram Combination Therapy - Participants with incomplete response at Week 8 who were randomized to this arm group received aripiprazole 3, 6, or 12 mg capsule, orally, once daily in combination with the escitalopram 10 or 20 mg orally, once daily plus one matching placebo capsule for 6 weeks, in Phase C. No dose adjustments were allowed for escitalopram during Phase C. Participants were titrated to the aripiprazole target dose of 12 mg/day at Week 9 if the initial 6 mg/day dose was tolerated.
