Brief Summary
This study aims to compare the efficacy and safety of lumateperone and cariprazine as adjuncts in patients with depression associated with bipolar I using standardized efficacy assessment tools such as the Montgomery-Åsberg Depression Rating Scale (MADRS) and Clinical Global Impression bipolar severity scale (CGI-BP-S) and recording treatment emergent adverse effect. Participants will undergo baseline assessment on day 0 using these scales. Follow-up assessments using MADRS and CGI scales will be conducted at Day 15, Day 30 and Day 45. Safety analysis will be performed for all participants who receive at least one dose of study medication. Vitals and treatment-emergent adverse events (TEAEs) will be recorded at every visit

Outcome Measures
Primary Outcomes (1)
Change in Montgomery-Åsberg Depression Rating Scale (MADRS) score
Change in depressive symptom severity from baseline to Week 8, measured using the Montgomery-Åsberg Depression Rating Scale (MADRS) total score in patients with Bipolar I depressive episode receiving adjunctive lumateperone or cariprazine with mood stabilizers.
Baseline to Week 6 (Day 45)
Study Arms (2)
lumateperone plus mood stabilizer
EXPERIMENTALLumateperone administered as adjunctive therapy in addition to ongoing mood stabilizer treatment for bipolar I depressive episode
Cariprazine plus mood stabilizer
ACTIVE COMPARATORCariprazine administered as adjunctive therapy in addition to ongoing mood stabilizer treatment for bipolar I depressive episode.
Interventions
Lumateperone administered as adjunctive therapy along with ongoing mood stabilizer treatment in patients with Bipolar I depressive episode
Cariprazine administered as adjunctive therapy along with ongoing mood stabilizer treatment in patients with Bipolar I depressive episode.
