Study Arms (3)
Bitopertin 10 mg + Antipsychotics
EXPERIMENTALTreatment Period 1: Participants will receive bitopertin 10 milligrams (mg) tablet orally once daily for 24 weeks. Treatment Period 2: Participants will receive bitopertin 10 mg tablet orally once daily for 28 weeks (up to Study Week 52). After Week 52 there will be a 4-week washout period for at least 50 percent (%) of participants (up to Week 56). Long-Term Extension: After Week 56, participants will enter the long term extension period and continue to receive bitopertin 10 mg tablet orally once daily up to 3 years. In addition, throughout the study, participants will continue their same stable antipsychotic treatment as they were receiving prior to entry in the study.
Bitopertin 20 mg + Antipsychotics
EXPERIMENTALTreatment Period 1: Participants will receive bitopertin 20 mg tablet orally once daily for 24 weeks. Treatment Period 2: Participants will receive bitopertin 20 mg tablet orally once daily for 28 weeks (up to Study Week 52). After Week 52 there will be a 4-week washout period for at least 50% of participants (up to Week 56). Long-Term Extension: After Week 56, participants will enter the long term extension period and continue to receive bitopertin 20 mg tablet orally once daily up to 3 years. In addition, throughout the study, participants will continue their same stable antipsychotic treatment as they were receiving prior to entry in the study.
Placebo
PLACEBO COMPARATORTreatment Period 1: Participants will receive bitopertin matching placebo tablet orally once daily for 24 weeks. Treatment Period 2: Participants will receive bitopertin matching placebo tablet orally once daily for 32 weeks (up to Study Week 56). Long-Term Extension: After Week 56, participants will enter the long term extension period and will be switched to (in blinded manner) bitopertin 10 mg tablet orally once daily up to 3 years. In addition, throughout the study, participants will continue their same stable antipsychotic treatment as they were receiving prior to entry in the study.
Interventions
Participants will receive 10 mg or 20 mg of bitopertin.
Participants will continue to receive their stable antipsychotic regiment throughout the study. Study protocol does not specify any particular antipsychotic drug and regimen.
