简要总结

This is a global, randomized, double-blind, placebo-controlled study in pediatric patients aged 5 to 17 years with a primary diagnosis of irritability associated with ASD based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Text Revision (DSM-5-TR) and confirmed by the Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL). Patients aged 13 to 17 years are eligible for enrollment. Enrollment of patients aged 5 to 12 years will be initiated when PK data supporting dose selection for this age group are available.The study will be conducted in 3 phases:

• Screening Period (up to 14 days) during which patient eligibility will be assessed.

• Double-blind Treatment Period (DBTP) (6 weeks) during which all patients will be randomized in a 1:1:1 ratio to receive either lumateperone high dose, lumateperone low dose, or placebo as a once daily dose, stratified by country and age category.

o Patients who discontinue study drug prior to Visit 8 (Day 43) but agree to continue participation in the DBTP should be seen at all subsequent protocol-defined visits through Visit 8 (Day 43) and should also return for the Safety Follow-up (SFU) Visit. Study drug will not be dispensed to these patients after discontinuation. Clinical management of these patients will be at the discretion of the Investigator.

o Patients who discontinue study drug prior to Visit 8 (Day 43) and do not agree to continue participation in the DBTP should be seen for an early termination (ET) Visit as soon as possible and should return for the SFU Visit 1 week after the ET Visit. Study drug will not be dispensed to these patients after discontinuation. Clinical management of these patients will be at the discretion of the Investigator.

• Safety Follow-up Period (1 week) during which all patients will return to the clinic for a SFU Visit approximately 1 week after the last dose of study drug
