Brief summary

The main aim of the study is to check how well vortioxetine 10 mg/day or 20 mg/day works and to check for side effects compared to a placebo on depression symptoms in Japanese teenagers aged 12 to 17 years with a diagnosis of Major Depressive Disorder (MDD). The overall time each participant will be in the study is about 20 weeks. This includes up to 15 days (about 2 weeks) to check who can take part, a 14-week period where everyone receives vortioxetine or a placebo, and after that, a 4-week period to check for any side effects after treatment. During the study, participants will visit their clinic 13 times.

Design outcomes

Primary

MeasureTime frameDescription
Change from Baseline in the Children Depression Rating Scale Revised version (CDRS-R) Total ScoreBaseline, Week 14The 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.

Secondary

MeasureTime frameDescription
Change from Baseline in the CDRS-R Total Score at Each Time PointBaseline, Week 2, 4, 6, 8, and 10The 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.
CDRS-R Response at Each Time PointWeek 2, 4, 6, 8, 10, and 14CDRS-R response is defined as at least 50 percent reduction in the CDRS-R total score from Baseline, calculated as the change from baseline divided by the result of subtracting 17 from the Baseline score. CDRS-R response at each time point will be reported.
Remission at Each Time PointWeek 2, 4, 6, 8, 10, and 14Remission is defined as less than or equal to 28 in the CDRS-R total score. Remission at each time point will be reported.
Change from Baseline in the Patient Health Questionnaire-9 for Adolescents (PHQ-A) at Each Time PointBaseline, Week 4, 6 and 14The PHQ-A is a participant-rated scale designed to screen for depressive symptoms in adolescents. The 9 depression items are rated on a 4-point scale (0=Not at all; 1=Several days; 2=More than half the days; and 3=Nearly every day). The total score can range from 0 to 27, with higher scores indicating greater severity of depression.
Change from Baseline in the Digit Symbol Substitution Test (DSST) at Each Time PointBaseline, Week 4 and 14The DSST is a paper-and-pencil cognitive test. After viewing a predetermined table of pairs of numbers and symbols, participants replace each symbol with its corresponding number, one by one. The number of correct symbols within the allowed time, usually 90 seconds, constitutes the score. The DSST score ranges from 0 to 133, with lower scores indicating lower cognitive function.
Change from Baseline in the Clinical Global Impression - Severity of Illness (CGI-S) Score at Each Time PointBaseline, Week 2, 4, 6, 8, 10, and 14The CGI-S provides the clinician's impression of the participant's current state of mental illness. The clinician uses his or her clinical experience of this participant population to rate the severity of the participant's current mental illness on a 7-point scale ranging from 1 (Normal - not at all ill) to 7 (among the most extremely ill participants).
Score in the Clinical Global Impression - Global Improvement (CGI-I) at Each Time PointWeek 4, 6, 8, 10, and 14The CGI-I provides the clinician's impression of the participant's improvement (or worsening). The clinician assesses the participant's condition relative to a baseline on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse).
Remission in the CGI-S Score at Each Time PointWeek 2, 4, 6, 8, 10, and 14Remission in the CGI-S score is defined as a CGI-S score of 1 or 2. Remission in the CGI-S score at each time point will be reported.
Response in the CGI-I Score at Each Time PointWeek 4, 6, 8, 10, and 14Response in the CGI-I Score is defined as defined as a CGI-I score of 1 or 2. Response in the CGI-I score at each time point will be reported.
Change from Baseline in the Sheehan Disability Scale - Adolescent Version (SDS-A) at Each Time PointBaseline, Week 4 and 14The SDS-A assesses functional impairment in 3 major life domains: school/work, social life/leisure activities, and family life/home responsibilities. The 3 life domains are rated on a 11-point scale from 0 (Not at all) to 10 (Extremely). The total score ranges from 0 to 30, with higher scores indicating greater pathology.
