E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to compare the efficacy of lumateperone administered orally once daily to that of placebo as measured by mean change from baseline to Day 43 in the total score on the rater-administered Montgomery-Åsberg Depression Rating Scale (MADRS) in patients with Bipolar Depression. |
|
E.2.2 | Secondary objectives of the trial |
The efficacy secondary objectives of this study are to compare the efficacy of lumateperone administered orally once daily to that of placebo in relation to:
• MADRS - Time course of improvement:
o as measured by absolute mean change from
baseline in the MADRS total score at each assessment time point;
o as measured in days from first dose date to the
earliest date that a ≥50% decrease in the MADRS total score from baseline
is observed);
o as measured by the proportion of treatment
responders where response is defined as a ≥50% decrease in the MADRS
total score from baseline at each assessment time point, including at Study
Day 43;
o as measured by the proportion of remitters
where remission is defined as a MADRS total score ≤12 at each assessment
time point, including at Study Day 43;
o The improvement in sleep, as measured by Item 4 (reduced sleep) on the
MADRS in patients with at least mild sleep disturba |

These episodes must be demarcated either by a partial or full remission of at least 2 months' duration or by a switch to an episode of opposite polarity.
9. The patient is considered treatment-resistant, defined as having a lifetime history
of treatment resistance (no remission) to ≥2 treatments with medications

systematic psychotherapy, or plans to initiate such therapy during the study.
