This is an in-clinic, single arm, open-label study assessing tachyphylaxis, tolerance, and withdrawal following repeated doses of Igalmi in adult males and females (18 to 65 years old, inclusive) with agitation associated with schizophrenia or bipolar disorder. Subjects will be screened for eligibility within 15 days of first dose and no study procedures will occur unless subjects provide written informed consent. Subjects will receive single doses of 180 μg of Igalmi as needed for the treatment of agitation over a period of 7 days followed by a 3- day follow-up period during which time no Igalmi will be administered in an effort to characterize any potential withdrawal. Subjects will sublingually self-administer Igalmi for an agitation episode that reaches a pre-dose PEC total score of 14 or greater, as determined by a trained rater. Safety assessments will be conducted before and after each dose. If the subject's agitation is recurrent or persistent, repeat doses of 90 µg may be administered (no more than 2 repeat doses within a 24-hour period) in the absence of any safety concerns or adverse events.
