An Extension Study to Assess Long-Term Safety and Tolerability of Adjunctive KarXT in Subjects With Inadequately Controlled Symptoms of Schizophrenia

This is a Phase 3, multicenter, 52-week, outpatient, open-label extension (OLE) study to evaluate the long-term safety and tolerability of adjunctive KarXT in subjects with schizophrenia with an inadequate response to their current antipsychotic treatment who previously completed the treatment period (Visit 8/Day 42 ± 3) of ARISE Study (KAR-012). The primary objective of the study is to assess the long-term safety and tolerability of adjunctive KarXT (a fixed dose combination of xanomeline and trospium chloride twice daily \[BID\]) in subjects with schizophrenia.
