An Open-label Study of Lumateperone as Adjunctive Therapy in the Treatment of Patients With Major Depressive Disorder

At the Screening/Baseline Visit (Visit 1/Day 1), which is the same visit as Visit 8/Day 43 of the lead-in study, eligible patients will receive open-label lumateperone 42 mg once daily for approximately 26 weeks. Patients will continue their background ADT from the lead-in study. Patients will be seen for weekly visits through Visit 5/Week 4. Thereafter, visits will occur every two weeks. A Safety Follow-up visit will occur on Visit 17/Day 197, approximately 2 weeks after the last dose of open-label lumateperone 42 mg.
