This study is for adults with schizophrenia, a mental health disorder that affects how a person thinks, feels, and behaves. The study is testing a medicine called brenipatide to see if it helps when combined with standard treatment compared to a non-active treatment (placebo). The study will last for about 15 months, with a 1-month screening, 12 months of treatment, and 2 months of follow-up. Participants will need to inject the study medicine themselves, keep a diary, and answer questionnaires.

Key Points:

• The study lasts approximately 15 months, with several visits and assessments.
• Participants must have a stable treatment plan and a reliable partner to help.
• People with certain mental health disorders or substance issues cannot join.

Participants should be comfortable with injections and keeping a diary. They should also be ready to commit to the full duration of the study and attend all required visits. This study may offer a chance to contribute to important research in schizophrenia treatment.
