简要总结

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.

•Subject is capable of providing signed Informed Consent Form before any study assessments will be performed
•Subject resides in a stable living situation, in the opinion of the Investigator
•Subject has identified a reliable informant/caregiver willing and able to assist with study activities as needed throughout the subject's participation in the study. The informant can complete the study visits assessments via phone (as per local regulations).

•Women of childbearing potential (WOCP), or men whose sexual partners are WOCP, must be able and willing to use at least 1 highly effective method of contraception during the study and for at least 1 menstrual cycle (e.g., 30 days) after the last dose of study drug. Sperm donation is not allowed for 30 days after the final dose of the study drug. A female subject is considered to be a WOCP after menarche and until she is in a postmenopausal state for 12 months or otherwise permanently sterile (for which acceptable methods include hysterectomy, bilateral salpingectomy, or bilateral oophorectomy).

•Risk for suicidal behavior during the study as determined by the Investigator's clinical assessment and/or Columbia-Suicide Severity Rating Scale (C-SSRS) as confirmed by the following:
•Subject answers "Yes" to "suicidal ideation" Item 4 (active suicidal ideation with some intent to act, without a specific plan) or Item 5 (active suicidal ideation with a specific plan and intent) on the C-SSRS
•Non-suicidal self-injurious behavior is not exclusionary
•Any clinically significant abnormalities, including any finding(s) from ECG, or laboratory test at Visit 6, and the physical examination, vital signs, at the EOT visit of Study KAR-012 that the Investigator, in consultation with the Medical Monitor are considered to jeopardize the safety of the subject
•Female subject is pregnant
•If, in the opinion of the Investigator (and/or Sponsor/ Medical Monitor), subject is unsuitable for enrollment in the study or subject has any finding that, in the view of the Investigator (and/or Sponsor /Medical Monitor), may compromise the safety of the subject or affect their ability to adhere to the protocol visit schedule or study requirements
•Risk of violent or destructive behavior as per Investigator's judgement
•Subjects participating in another investigational drug or device trial or planning on participating in another clinical trial during the study
•History or high risk of urinary retention, gastric retention, or narrow angle glaucoma as evaluated by the Investigator
