The CDRS-R is a clinician-rated scale to measure the severity of depression in children and adolescents. The CDRS-R is rated by a clinician following interviews with the child and parents/legal guardians and consists of 17 items out of which 3 items rate nonverbal observations (listless speech, hypoactivity, and depressed affect). Fourteen items are rated on a 7-point scale from 1 to 7, and 3 items (sleep disturbance, appetite disturbance, and listless speech) are scored on a 5-point scale from 1 to 5. The total score ranges from 17 (normal) to 113 (severe depression). Higher scores indicate greater severity of depression.

The CDRS-R was rated by a clinician following interviews with the child and parent and consisted of 17 items out of which 3 items rated nonverbal observations (listless speech, hypoactivity, and depressed affect). Fourteen items were rated on a 7-point scale from 1 to 7, and 3 items (sleep disturbance, appetite disturbance, and listless speech) were scored on a 5-point scale from 1 to 5. A rating of 1 indicated normal functioning and a higher number indicated a greater degree of depression. The total score ranged from 17 (normal) to 113 (severe depression). Least square (LS) mean was estimated using a restricted maximum likelihood (REML)-based Mixed Model Repeated Measurements (MMRM) approach.

MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (such as apparent sadness, reported sadness, inner tension). MADRS corresponds to core symptoms of depression, and rated on a 7-point Likert scale from 0 (symptoms absent) to 6 (severe depression) with a total possible score range from 0 to 60. Higher scores indicate greater severity of symptoms. A negative change from Baseline indicates improvement.

The CSFQ-14 is a structured self reported questionnaire designed to measure illness- and medication-related changes in sexual functioning consisting of 14 items that measure sexual functioning as a total score (14 items) and on the subscales of pleasure (1 item), desire/frequency (2 items), desire/interest (3 items), arousal (3 items), and orgasm (3 items), rated on an 5 point scale from 1 to 5 with a total score range from 14 to 70. Higher scores reflect higher sexual functioning. A positive change from Baseline indicates that symptoms have improved. The primary analysis was based on a mixed model for repeated measurements (MMRM) analysis of covariance with treatment, center, week, treatment-by-week interaction as fixed effects, Baseline CSFQ-14 total score-by-week as covariate, and a completely unstructured covariance matrix.

MADRS is a 10-item clinician rated scale that measures overall severity of depressive symptoms (such as apparent sadness, reported sadness, inner tension) rated on a 7-point Likert scale from 0 (symptoms absent) to 6 (severe depression) with a total possible score range from 0 to 60. Higher scores indicate greater severity of symptoms. A negative change from Baseline indicates that symptoms have improved. An analysis of covariance (ANCOVA) model was used with change in MADRS total score as a dependent variable, treatment as a fixed effect and the baseline MADRS total score as a covariate.

Treatment-emergent adverse events (TEAE) are adverse events with an onset that occurs after receiving study drug and within 30 days after receiving the last dose of study drug. A TEAE may also be a pretreatment adverse event or a concurrent medical condition diagnosed prior to the date of first dose of study drug that increases in severity after the start of dosing.

Serious treatment-emergent adverse events (serious-TEAE) are adverse events with an onset that occurs after receiving study drug and within 30 days after receiving the last dose of study drug. A serious-TEAE may also be a pretreatment adverse event or a concurrent medical condition diagnosed prior to the date of first dose of study drug that increases in severity after the start of dosing. Serious Adverse Events include adverse events that result in death, require either inpatient hospitalization or the prolongation of hospitalization, are life-threatening, result in a persistent or significant disability/incapacity or result in a congenital anomaly/birth defect. Other important medical events, based upon appropriate medical judgment, may also be considered serious adverse events if a trial participant's health is at risk and intervention is required to prevent an outcome mentioned.

A standard 12-lead ECG was performed at the designated study visits. The central reader reviewed and recorded the intervals (PR, QRS, RR, QT, and corrected QT interval \[QTc\]), and interpreted the ECG using 1 of the following categories: within normal limits or abnormal. The number of participants with at least one post-baseline potentially clinically significant ECG finding is reported. bpm = beats per minute; QTcB = QT interval corrected using Bazett's formula; QTcF = QT interval corrected using Fridericia's formula.

The intensity (severity) of each AE was defined as: * Mild: caused minimal discomfort and did not interfere in a significant manner with normal activities. * Moderate: sufficiently uncomfortable to produce some impairment of normal activities. * Severe: incapacitating, preventing the patient from participating in normal activities. The causal relationship between an AE and study drug was assessed by the investigator as Probable, Possible or Not Related; Related=AEs with causality of Possibly or Probably. A serious AE (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, led to a congenital anomaly/birth defect, or was an important medical event that either jeopardized the patient, required intervention to prevent any of the SAEs defined above, a suicide attempt or an abortion.

Participants with at least one potentially clinically significant post-baseline vital sign finding. The definition of clinically significant is included in the table below for each parameter. SSBP = supine systolic blood pressure; SDBP = supine diastolic blood pressure.

Subjects will report the number of binge eating episodes in the week preceding the final visit (Week 12 of treatment), both to the investigator and via daily eating journals at all 9 visits. The outcome measure was the change in number of episodes from Week 0 (baseline) to the final visit (Week 12).

The Montgomery Åsberg Depression Rating Scale (MADRS) is a depression rating scale consisting of 10 items, each rated 0 (no symptom) to 6 (severe symptom). The 10 items represent the core symptoms of depressive illness. The rating should be based on a clinical interview with the patient, moving from broadly phrased questions about symptoms to more detailed ones, which allow a precise rating of severity, covering the last 7 days. Total score from 0 to 60. The higher the score, the more severe, thus, a negative change (or decrease) from baseline indicates a reduction (or improvement) in symptoms.

The DSST assesses relative contributions of speed, memory, executive function and visual scanning. Participants are required to copy symbols that are paired with simple geometric shapes or numbers within a specific time for a total possible score of 0 to 133. Higher scores-correct number of symbols reflects greater objective cognitive functioning. An increase in score represents an improvement in an integrated measure of cognitive function. An Analysis of Covariance (ANCOVA) model was used with treatment and center as fixed factors and the Baseline value as a covariate.
