E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to confirm the efficacy of lumateperone 42 mg administered orally once daily compared with that of placebo as measured by mean change from baseline to Day 43 in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score in patients with bipolar depression with mixed features or MDD with mixed features. |
|
E.2.2 | Secondary objectives of the trial |
Key Secondary Objective: The key secondary objective of this study is to confirm the efficacy of lumateperone 42 mg administered orally once daily compared with that of placebo as measured by mean change from baseline to Day 43 in Clinical Global Impression Scale–Severity (CGI-S) score in patients with bipolar depression with mixed features or MDD with mixed features
Safety Objective: The safety objective of this study is to determine the safety and tolerability of lumateperone administered orally once daily compared with that of placebo in patients with bipolar depression and MDD as assessed by adverse events (AEs); clinical laboratory results; vital sign measures; electrocardiogram (ECG) results; suicidality as assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS); manic symptoms as assessed by the YMRS; and extrapyramidal symptoms (EPS) as assessed by Abnormal Involuntary Movement Scale (AIMS), Barnes Akathisia Rating Scale (BARS), and Simpson Angus Scale (SAS) scales |
