Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is an open label study of the treatment satisfaction, efficacy and tolerability of xanomeline/ trospium in a population of 172 participants diagnosed with schizophrenia in the early phase of illness. Participants will be followed for 24 weeks with scheduled assessments conducted by centralized raters, local mental health professionals and self-assessments completed by patients. Recruitment will be based on insufficient efficacy of previous antipsychotic or due to dissatisfaction with treatment as a result of unacceptable side effects on previous antipsychotic/patient choice, with approximately 50% for each enrollment criteria. Participants who present with both insufficient efficacy and unacceptable side effects will be considered as belonging to the insufficient efficacy subgroup. Treatment and assessments will be identical for the 2 groups. Primary outcome for participants enrolled will be improvement in overall treatment satisfaction as measured by the MSQ.
