Official Title ICMJE | An Open-label Study to Assess the Long-term Safety, Tolerability, and Efficacy of KarXT in De Novo Subjects With DSM-5 Schizophrenia | ||||
Brief Summary | This is a Phase 3, multicenter, 56-week, outpatient, open-label (OL) study to evaluate the long-term safety, tolerability, and efficacy of KarXT in de novo subjects with Diagnostic and Statistical Manual-Fifth Edition (DSM-5) schizophrenia. In this OL study, all subjects will receive KarXT (a fixed combination of xanomeline 125 mg and trospium chloride 30 mg twice daily [BID]) for up to 52 weeks. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with a DSM-5 diagnosis of schizophrenia. The secondary objective of this study is to assess the long-term efficacy and characterize the pharmacokinetics of xanomeline and trospium after administration of KarXT. | ||||

Study Design ICMJE | Allocation: N/A Intervention Model: Single Group Assignment Masking: None (Open Label) Primary Purpose: Treatment |
||||
Condition ICMJE | Schizophrenia | ||||
Intervention ICMJE | Drug: Xanomeline and Trospium Chloride Capsules
Oral xanomeline 50 mg/trospium 20 mg BID on days 1-2 followed by xanomeline 100 mg/trospium 20 mg BID on days 3-7. The dose is increased to xanomeline 125 mg/trospium 30 mg BID on days 8-364 unless the subject is experiencing adverse events from the xanomeline 100 mg/ trospium 20 mg dose. Subjects who were increased to xanomeline 125 mg/trospium 30 mg will have the option to return to xanomeline 100 mg/ trospium 20 mg depending on clinical response and tolerability. Re-escalation to 125/30 BID or re-titration in cases in which the subject has been off KarXT for a longer period of time (at least a week) is allowed and will require a discussion between the principal investigator and the medical monitor.
