入选标准
- •Rollover Participants
- •Completed 6 weeks of post-randomization treatment in Trial CVL-2312001 or CVL-231-2002 and who, in the opinion of the investigator, could potentially benefit from treatment with emraclidine for schizophrenia.
- •Outpatient status at last day of treatment period (Day 45) of the preceding double-blind trial (CVL-231-2001 or CVL-231-2002) defined as follows: • Ability to be discharged from the hospital on Day 45 of Trial CVL-2312001 or CVL-231-2002 • Hospitalization for psychosocial reasons (eg, homelessness or need for shelter that is unrelated to the participant's underlying psychiatric condition) will be considered outpatient status • Participants remaining in hospital at Day 45 of Trial CVL-231-2001 or CVL-231-2002 (for other than psychosocial reasons) will be permitted to enroll in Trial CVL-231-2003 at Day 45 of the double-blind trial if they are planned to be discharged from the hospital before the Week 1 visit of Trial CVL-231-2003 • Participants not discharged by the Week 1 visit of Trial CVL-231-2003 must be withdrawn
- •Agree to comply with the following contraception requirements during the trial and for 7 days after the last dose of IMP: • Sexually active women of childbearing potential must use acceptable (at minimum) contraception as defined in Section 10.4.1.1 of the Protocol.
- •Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in Section 10.1.
- •of the Protocol
- •Ability, in the opinion of the investigator, to understand the nature of the trial, participate in trial visits, and comply with protocol requirements, including the prescribed dosage regimens, scheduled visits, laboratory tests, outcomes measures, and other trial procedures.
- •De Novo Participants
- •Male and female participants, ages 18 to 65 years, inclusive, at the time of signing the ICF.

Hospitalization for psychosocial reasons (eg, homelessness or need for shelter that is unrelated to the participant's underlying psychiatric condition) will be considered outpatient status. Participants may be hospitalized for not more than 14 days during the conversion to emraclidine with the approval of the medical monitor but must be discharged from the hospital before the Week 1 visit.
- •Scores as follows (normal to mild symptoms) at the time of signing the ICF and Baseline (Day 1): • All individual items of the SAS <2 • All individual items (Items 1-7) of the AIMS <2 • Clinical global assessment item of the BARS <3

- •Resides in a stable living environment as demonstrated by the ability to provide contact information for themselves and/or family/friend/caregiver.
