Brief Summary:
Schizophrenia is a common and severe psychiatric illness characterized by extreme disturbances of cognition and thought, affecting language, perception and sense of self. This study will assess how safe and effective cariprazine is in treating adult participants with schizophrenia in Japan and Taiwan. Adverse events and change in disease activity will be assessed.
Cariprazine (VRAYLAR) is an approved drug for the treatment of schizophrenia in the United States. In the first 6-week period, participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. In the next 18-week period, participants will have the option to receive 1 of 3 doses of cariprazine. Approximately 250 adult participants, 18-65 years of age with schizophrenia will be enrolled in approximately 55 sites across Taiwan and Japan.
Participants will receive oral capsules of Cariprazine or placebo for the 6-week Double-blind Period (DBP). Upon completion of 6-week DBP, participants will be eligible to receive oral capsules of Cariprazine for additional 18 weeks in the Blinded Extension Period (BEP), followed by an 8-week safety follow-up period.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
Detailed Description:
Per the final protocol amendment 3, the number of dosing arms in the 6-week DBP of the study changed from 3 to 2. Participants enrolled in the study through Protocol Amendment 2 and who were randomized to the arm that was eliminated, remained in that arm through DBP and their data are displayed by that arm for the DBP portion of the study in participant flow, baseline characteristics and safety sections. Data for all endpoints are presented as planned per final SAP.
