New schizophrenia drug tested for Long-Term safety in major trial
NCT ID NCT07114874
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 trial is testing the long-term safety of the drug NBI-1117568 in 600 adults with schizophrenia. Participants will receive the drug and be monitored for side effects over time. The study is open-label, meaning everyone knows they are getting the drug, and it focuses on safety rather than how well the drug works.
