Group Intervention Description Open-Label Phase: SAGE-217 SAGE-217 Participants self-administered SAGE-217, 30 milligrams (mg), oral capsule, once daily (QD) in the evening from Day 1 to Day 14. Double-Blind Phase: Placebo Placebo Following the OL Phase, participants who exhibited a Hamilton Rating Scale for Depression (HAM-D) response, defined as a greater than or equal to (≥) 50% reduction from baseline in HAM-D total score were to be randomized to receive SAGE-217 matching placebo capsule, orally, QD, in the evening, in a total of five, 14-day treatment periods, each separated by a 6-week follow-up period during the 40-week DB Phase of the study. However, no participants were randomized to receive SAGE-217 matching placebo due to early study termination. Double-Blind Phase: SAGE-217 SAGE-217 Following the OL Phase, participants who exhibited a HAM-D response defined as a ≥ 50% reduction from baseline in HAM-D total score to SAGE-217 were randomized to receive SAGE-217, 30 mg, oral capsule, QD, in the evening, up to study termination date (i.e., up to approximately 22 weeks) during the DB Phase of the study.
- Primary Outcome Measures
Name Time Method Time to Relapse During the DB Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) Time to relapse was defined as days from the first dose of the study drug in the DB Phase to the day of relapse during the DB Phase. Participant was considered to have relapsed if: 2 consecutive HAM-D scores were ≥ 18 assessed 7 to 14 days apart, any worsening of depression requiring hospitalization, Investigator-determined risk of suicide, or any other clinically relevant event whether or not hospitalization was required. HAM-D is a scale used to rate depression in participants who were already diagnosed as depressed. The HAM-D total score comprised a sum of 17 individual item scores. Items scored in a range of 0 to 2 included: insomnia, somatic symptoms, genital symptoms, loss of weight, and insight. Items scored in a range of 0 to 4 included: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety, hypochondriasis. The HAM-D total score could range from 0 (not depressed) to 52 (severely depressed). Higher scores indicated more depression.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With HAM-D Response at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) HAM-D response was defined as having a 50% or greater reduction from baseline in HAM-D total score. The HAM-D total score comprised a sum of 17 individual item scores. Items scored in a range of 0 to 2 included: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. Items scored in a range of 0 to 4 included: agitation, depressed mood (sadness, hopeless, helpless, worthless), feelings of guilt, suicide, work and activities, retardation (slowness of thought and speech; impaired ability to concentrate; decreased motor activity), anxiety (psychic and somatic), hypochondriasis. The HAM-D total score could range from 0 (not depressed) to 52 (severely depressed). Higher scores indicated more depression.
Percentage of Participants With HAM-D Remission at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) HAM-D remission was defined as having a HAM-D total score of ≤ 7. The HAM-D total score comprised a sum of 17 individual item scores. Items scored in a range of 0 to 2 included: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. Items scored in a range of 0 to 4 included: agitation, depressed mood (sadness, hopeless, helpless, worthless), feelings of guilt, suicide, work and activities, retardation (slowness of thought and speech; impaired ability to concentrate; decreased motor activity), anxiety (psychic and somatic), hypochondriasis. The HAM-D total score could range from 0 (not depressed) to 52 (severely depressed). Higher scores indicated more depression.
Percentage of Participants Who Relapsed During the DB Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) Participant was considered to have relapsed if: 2 consecutive HAM-D scores were ≥ 18 assessed 7 to 14 days apart, worsening of depression requiring hospitalization, Investigator-determined risk of suicide, or other clinically relevant events whether hospitalization was required. HAM-D scale was used to rate depression in participants who were diagnosed as depressed. Total score is a sum of 17 individual item scores. Items in a range of 0-2 included: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. Items in a range of 0-4 included: agitation, depressed mood (sadness, hopeless, helpless, worthless), feelings of guilt, suicide, work and activities, retardation (slowness of thought and speech; impaired ability to concentrate; decreased motor activity), anxiety (psychic and somatic), hypochondriasis. Total score could range from 0 (not depressed)- 52 (severely depressed). Higher scores indicated more depression.
Change From Baseline in the 17-Item HAM-D Total Score at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Baseline [Day 1] of DB Phase) up to Day 153 (i.e., up to 22 weeks) The 17-item HAM-D scale was used to rate the severity of depression in participants who were already diagnosed as depressed. The HAM-D total score comprised a sum of 17 individual item scores. Items scored in a range of 0 to 2 included: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. Items scored in a range of 0 to 4 included: agitation, depressed mood (sadness, hopeless, helpless, worthless), feelings of guilt, suicide, work and activities, retardation (slowness of thought and speech; impaired ability to concentrate; decreased motor activity), anxiety (psychic and somatic), hypochondriasis. The HAM-D total score could range from 0 (not depressed) to 52 (severely depressed). Higher scores indicated more depression. A negative change from baseline indicated improvement.
Percentage of Participants With Clinical Global Impression - Improvement (CGI-I) Response at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) The CGI-I employs a 7-point Likert scale to measure the overall improvement in the participant's condition posttreatment. The Investigator rated the participant's total improvement whether or not it was due entirely to drug treatment. Response choices included: 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, and 7=very much worse. The CGI-I is only rated at posttreatment assessments. By definition, all CGI-I assessments are evaluated against baseline conditions. Higher score indicated worse condition. CGI-I response was defined as having a CGI-I score of "very much improved" or "much improved."
Change From Baseline in Clinical Global Impression - Severity (CGI-S) Score at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Baseline [Day 1] of DB Phase) up to Day 153 (i.e., up to 22 weeks) The CGI-S uses a 7-point Likert scale to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with participants who had the same diagnosis. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating as 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; and 7= among the most extremely ill participant. A higher score indicated extreme illness. A negative change from baseline indicated improvement (a higher absolute number indicating more illness).
Change From Baseline in 9-Item Patient Health Questionnaire (PHQ-9) Score at the End of Each 14-Day Treatment Period in the DB Phase Day 56 (Baseline [Day 1] of DB Phase) up to Day 153 (i.e, up to 22 weeks) The PHQ-9 is a participant-rated depressive symptom severity scale. To monitor severity over time participants in current treatment for depression, participants completed the questionnaires at baseline and at regular intervals thereafter. Scoring was based on responses to specific questions, as follows: 0=not at all; 1=several days; 2=more than half the days; and 3=nearly every day. The PHQ-9 total score was calculated as the sum of the 9 individual item scores and ranged from 0 to 27. The PHQ-9 total score was categorized as follows: 1 to 4=minimal depression, 5 to 9=mild depression, 10 to 14=moderate depression, 15 to 19=moderately severe depression; and 20 to 27=severe depression. Higher score indicated severe depression. A negative change from baseline indicated improvement.
Time to Relapse During The DB Phase for Participants Who Achieved HAM-D Remission in the OL Phase Day 56 (Day 1 of DB Phase) up to Day 153 (i.e., up to 22 weeks) Time to relapse was defined as days from the first dose of the study drug in the DB Phase to the day of relapse during the DB Phase. Participant was considered to have relapsed if: 2 consecutive HAM-D scores were ≥18 assessed 7 to 14 days apart, any worsening of depression requiring hospitalization, Investigator-determined risk of suicide, or any other clinically relevant event whether or not hospitalization was required. HAM-D is a scale used to rate depression in participants who were already diagnosed as depressed. The HAM-D total score comprised a sum of 17 individual item scores. Items scored in a range of 0 to 2 included: insomnia, somatic symptoms, genital symptoms, loss of weight, and insight. Items scored in a range of 0 to 4 included: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety, hypochondriasis. The HAM-D total score could range from 0 (not depressed) to 52 (severely depressed). Higher scores indicated more depression.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) From the first dose of study drug up to the end of the study (i.e., up to approximately 22 weeks) An adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. A TEAE was defined as an AE with onset after the start of study drug, or any worsening of a pre-existing medical condition/AE with onset after the start of study drug and throughout the study.
