PlaceboPlacebo tabletsThe placebo arm consisted of 3 placebo capsules to match AZD7268 capsules dosed orally in the morning and evening. In addition, 2 placebos to match encapsulated escitalopram tablets were dosed orally in the morning only.
AZD7268AZD7268The AZD7268 15 mg BID arm consisted of 3 AZD7268 5 mg capsules dosed orally in the morning and evening. In addition, 2 placebo tablets to match encapsulated escitalopram tablets were dosed orally in the morning only.

EscitalopramEscitalopramThe escitalopram 20 mg QD arm consisted of 3 placebo to match AZD7268 capsules dosed orally in the morning and evening. In addition, during Week 1, one encapsulated 10-mg escitalopram tablet and 1 placebo to match encapsulated escitalopram tablet were dosed orally in the morning only. During Weeks 2 through 4, two encapsulated 10-mg escitalopram tablets were dosed orally in the morning only.
EscitalopramPlacebo capsulesThe escitalopram 20 mg QD arm consisted of 3 placebo to match AZD7268 capsules dosed orally in the morning and evening. In addition, during Week 1, one encapsulated 10-mg escitalopram tablet and 1 placebo to match encapsulated escitalopram tablet were dosed orally in the morning only. During Weeks 2 through 4, two encapsulated 10-mg escitalopram tablets were dosed orally in the morning only.
Primary Outcome Measures
NameTimeMethod
Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score Change From Baseline to Week 4.Baseline, Week 4

MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). Change from baseline was calculated as Week 4 value minus baseline value. \[observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)\]

Secondary Outcome Measures
NameTimeMethod
Montgomery-Åsberg Depression Rating Scale (MADRS) ResponseWeek 4

Number of patients with MADRS response at Week 4. MADRS response is defined as \>=50% reduction in MADRS total score from baseline. MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). MADRS response at Week 4 is calculated using last observation carried forward (LOCF). \[Full Analysis Set (FAS)\]

Montgomery-Åsberg Depression Rating Scale (MADRS) RemissionWeek 4

Number of patients, who achieved MADRS remission at week 4. Remission is defined as a MADRS total score \<= 10. MADRS total score, sum of 10 item scores (each on a 0 (best value) to 6 (worst value)scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 60 (the worst). MADRS remission at Week 4 is calculated using last observation carried forward (LOCF). \[Full Analysis Set (FAS)\]

Hamilton Rating Scale for Depression (HAM-D) Total Score Change From Baseline to Week 4.Baseline, Week 4

HAM-D total score, sum of 17 item scores (each on a 0 to 2 or 0 to 4 scale), assesses the severity of depressive symptoms on a continuous scale from 0 (the best) to 52 (the worst). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. \[observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)\]

Clinical Global Impression - Severity (CGI-S) Score Change From BaselineBaseline, Week 4

CGI-S assesses global illness severity, i.e. the patient's current clinical state, on a continuous scale from 1 ("Normal, not ill") to 7 ("Among the most extremely ill patients"). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. \[observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)\]

Hamilton Rating Scale for Anxiety (HAM-A) Total Score Change From BaselineBaseline, Week 4

HAM-A total score, sum of 14 item scores (each on a 0 to 4 scale), assesses the severity of anxiety symptoms on a continuous scale from 0 (the best) to 52 (the worst). Change from baseline to Week 4 was calculated as Week 4 value minus baseline value. \[observed cases, Mixed Model Repeated Measurement (MMRM), Full Analysis Set (FAS)\]
