• Subject has been taking an antipsychotic for at least six weeks prior to Screening and has had no change in antipsychotic medication(s) (minor dose adjustments for tolerability purposes may be permitted after Medical Monitor and Sponsor review) for at least six weeks prior to Screening.

You may not qualify if…

• Subject has any clinically significant unstable medical condition or any clinically significant chronic disease that in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in the study, including any clinically significant hematological (including deep vein thrombosis) or bleeding disorder, renal, metabolic, endocrine, pulmonary, gastrointestinal, urological, cardiovascular, hepatic, neurologic or allergic disease (except for untreated seasonal allergies that are asymptomatic at the time of dosing).
• Subject has a disorder or history of a condition, or previous gastrointestinal surgery (eg, cholecystectomy, vagotomy, bowel resection) that may interfere with drug absorption, distribution, metabolism, excretion, gastrointestinal motility, or pH, or a history of clinically significant abnormality of the hepatic or renal system, or a history of malabsorption (uncomplicated cholecystectomy, appendectomy, and hernia repair will be acceptable).
• Subject has a DSM 5 diagnosis or presence of symptoms consistent with a DSM 5 diagnosis other than schizophrenia. Exclusionary disorders include but are not limited to alcohol use disorder (within past 12 months), substance (other than nicotine or caffeine) use disorder within past 12 months, major depressive disorder, bipolar I or II disorder, schizoaffective disorder, obsessive compulsive disorder, and posttraumatic stress disorder. Symptoms of mild to moderate mood dysphoria or anxiety are allowed so long as these symptoms are not the primary focus of treatment.
• Subject answers "yes" to "Suicidal Ideation" Items 4 (active suicidal ideation with some intent to act, without specific plan) or Item 5 (active suicidal ideation with specific plan and intent) on the Columbia-Suicide Severity Rating Scale (C SSRS) at Screening (ie, in the past 1 month) or at any subsequent C SSRS assessment prior to dosing (ie since last visit).
