Summary

This is a Phase 2, randomized, double-blinded, placebo-controlled, inpatient study to examine the efficacy, safety, and tolerability profile of KarXT in adult subjects diagnosed with DSM-5 schizophrenia who are in an acute exacerbation phase. The primary objective of the study is to assess the efficacy of KarXT (a fixed combination of xanomeline and trospium chloride) (xanomeline 125 mg/trospium 30 mg twice daily \[BID\]) versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a Diagnostic and Statistical Manual-Fifth Edition (DSM-5) diagnosis of schizophrenia. The secondary objectives of the study are to assess overall safety and tolerability of KarXT in adult inpatients with a DSM-5 diagnosis of schizophrenia.

Conditions

Interventions

DRUG

Xanomeline and Trospium Chloride Capsules

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 8-34 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. Dosing must not change after Visit 7 of the study (at 21 ± 2 days of dosing) and may be decreased for tolerability reasons no more than once during the study.
