What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Incidence of Overall Adverse Events (AEs), Serious Adverse Events (SAEs), and Adverse Events (AEs) Leading to Discontinuation

    Number of Participants with overall Adverse Events (AEs), Serious Adverse Events (SAEs), and Adverse Events (AEs) leading to discontinuation

    Measured: From first dose of study drug to last study visit (27 weeks)

Secondary outcomes (9)
  1. Frequency of Suicidal Ideation (SI) and Suicidal Behavior (SB) Using the Columbia - Suicide Severity Rating Scale (C-SSRS)

    Number of participants with suicidal ideation (SI) and suicidal behavior (SB) using the Columbia - Suicide Severity Rating Scale (C-SSRS). The C-SSRS is a tool designed to systematically assess and track suicidal behavior and suicidal ideation for life time, one month prior to the screening visit for suicidal ideation and 6 months prior to the screening visit for suicidal behavior, and throughout the study. The strength of this suicide classification system is in its ability to comprehensively identify suicidal events while limiting the over-identification of suicidal behavior.

    Measured: Overall post Open-label Baseline treatment period (26 weeks)

  2. Severity of Suicidal Ideation (SI) and Suicidal Behavior (SB) Using the Columbia - Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS is a tool designed to systematically assess and track suicidal behavior and suicidal ideation for life time, one month prior to the screening visit for suicidal ideation and 6 months prior to the screening visit for suicidal behavior, and throughout the study. The strength of this suicide classification system is in its ability to comprehensively identify suicidal events while limiting the over-identification of suicidal behavior.

    Measured: Overall post Open-label Baseline treatment period (26 weeks)

  3. Time to Relapse During the 26-week Open-label Treatment Period for Subjects Who Demonstrated a Clinical Response to 4 Weeks of Treatment With SEP-363856

    Relapse is defined as the earliest occurrence of any of the following: - An increase in PANSS total score by ≥ 30% from the PANSS total score at clinical response and a CGI-S score ≥ 3; - Re-hospitalization for worsening of psychosis; - Emergence of suicidality, homicidality, and/or risk of harm to self or others.

    Measured: From the time of clinical response to relapse or censor (one day after the last study drug dose)

  4. Rate of Relapse During the 26-week Open-label Treatment Period for Subjects Who Demonstrated a Clinical Response to 4 Weeks of Treatment With SEP-363856

    Relapse is defined as the earliest occurrence of any of the following: - An increase in PANSS total score by ≥ 30% from the PANSS total score at clinical response and a CGI-S score ≥ 3; - Re-hospitalization for worsening of psychosis; - Emergence of suicidality, homicidality, and/or risk of harm to self or others.

    Measured: From the time of clinical response to relapse or censor (one day after the last study drug dose)

  5. Changes From Double-blind Baseline of Study SEP361-201 and Open-label Baseline of Study SEP361-202 in Positive and Negative Syndrome Scale (PANSS) Total Score and Subscale Scores (Positive, Negative, and General Psychopathology)

    PANSS is comprised of 30 items and 3 subscales (Positive, Negative, General Psychopathology). An anchored Likert scale from 1 - 7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. Individual items are then summed to determine scores for the 3 subscales, as well as a total score. PANSS Positive subscale score range: 7-49. PANSS Negative subscale score range: 7-49. PANSS General Psychopathology subscale score range: 16-112. PANSS total score range: 30-210.

    Measured: Double-blind Baseline (DB BLN), Open-label Baseline (OL BLN), Week 26 (Wk 26)

  6. Change From Double-blind Baseline of Study SEP361-201 and Open-label Baseline of Study SEP361-202 in Clinical Global Impression - Severity (CGI-S) Score

    The CGI-S is a single-item clinician-rated assessment of the subject's current illness state on a 7-point scale (score range: 1-7), where a higher score is associated with greater illness severity.

    Measured: Double-blind (DB) Baseline, Open-label (OL) Baseline, Week 26

  7. Change From Double-blind Baseline of Study SEP361-201 and Open-label Baseline of Study SEP361-202 in Brief Negative Symptom Scale (BNSS) Total Score

    The BNSS is a rating scale to measure the current level of severity of negative symptoms in schizophrenia and schizoaffective disorder. The measure is comprised of 13 individual items organized in 6 subscales. The 13 individual items provide a composite total score (ranging from 0 to 78). Each of the items are scored on a Likert-type 7-point scale from 0 - 6, where values of 0 indicates symptom is absent and a value of 6 means the symptom is a severe form.

    Measured: Double-blind (DB) Baseline, Open-label (OL) Baseline, Week 26

  8. Change From Double-blind Baseline of Study SEP361-201 and Open-label Baseline of Study SEP361-202 in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score

    The MADRS is a clinician-rated assessment of the subject's level of depression. The measure contains 10 items that measure apparent and reported sadness, inner tension, reduced sleep and appetite, difficulty concentrating, lassitude, inability to feel, and pessimistic and suicidal thoughts. Each item is scored in a range of 0 to 6 points, with higher scores indicating increased depressive symptoms.

    Total score will be equal to the sum of the 10 items (range between 0 and 60).

    Measured: Double-blind (DB) Baseline, Open-label (OL) Baseline, Week 26

  9. Proportion of Subjects Who Achieved a Response, Defined as a 20% or Greater Improvement in Positive and Negative Syndrome Scale (PANSS) Total Score From Double-blind Baseline of Study SEP361-201

    PANSS is comprised of 30 items and 3 subscales (Positive, Negative, General Psychopathology). An anchored Likert scale from 1 - 7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. Individual items are then summed to determine scores for the 3 subscales, as well as a total score. PANSS Positive subscale score range: 7-49. PANSS Negative subscale score range: 7-49. PANSS General Psychopathology subscale score range: 16-112. PANSS total score range: 30-210.

    Measured: Week 26
