Outcome Measures
Primary Outcome Measures
- Change in PANSS Total Score From Baseline at Week 6 [Week 6]
The Positive and Negative Syndrome Scale (PANSS) is an interview-based measure of the severity of psychopathology in adults with psychotic disorders. The measure is comprised of 30 items and 3 subscales: the Positive subscale assesses hallucinations, delusions, and related symptoms; the Negative subscale assesses emotional withdrawal, lack of motivation, and similar symptoms; and the General Psychopathology subscale addresses other symptoms such as anxiety, somatic concern, and disorientation. 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. The PANSS total score is the sum of all 30 items and ranges from 30 through 210. A higher score is associated with greater illness severity.
Secondary Outcome Measures
- Proportion of Subjects Who Achieve a Response, Defined as 20% or Greater Improvement From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 6 [Week 6 (LOCF)]
The PANSS is an interview-based measure of the severity of psychopathology in adults with psychotic disorders. The measure is comprised of 30 items and 3 subscales: the Positive subscale assesses hallucinations, delusions, and related symptoms; the Negative subscale assesses emotional withdrawal, lack of motivation, and similar symptoms; and the General Psychopathology subscale addresses other symptoms such as anxiety, somatic concern, and disorientation. 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 a total score. The PANSS total score is the sum of all 30 items and ranges from 30 through 210. A higher score is associated with greater illness severity. The Last Observation Carried Forward (LOCF) endpoint is defined as the last data captured on Day 1 through 7 days after the final application of DSP-5423P.
- Treatment Continuation Rate at 28 Weeks and 52 Weeks [Open-Week 28 and Open-Week 52 in the open-label treatment phase]
Percentage of subjects who stay the study up to 28 weeks (196 days, all countries), and 52 weeks (364 days, in Japan) and its 95% confidence interval.
