Biomarker-guided care for teens and young adults with a first episode of psychosis

5/5 Biomarkers to Enhance Early Schizophrenia Treatment (BEEST)

NIH-funded research University of California, San Diego · NIH-11184375

This project tests whether brain scans and genetic tests can help doctors pick the right antipsychotic and decide about clozapine sooner for 12–20-year-olds having a first episode of psychosis.

What this research studies

If you join, you will have a resting-state brain scan and genetic testing plus regular clinical visits to track symptoms and side effects. The team will enroll about 410 young people with a first episode of psychosis and use three specific biomarkers to see who is unlikely to respond to first-line antipsychotics and who is at lower or higher risk for side effects like weight gain or agranulocytosis. Participants will be followed while clinicians use a biomarker-informed decision support approach versus usual care to guide whether to switch to clozapine. The study will compare symptom outcomes, safety, and treatment timing across groups to build a tool to help treatment decisions in early psychosis.

Who could benefit from this research

Good fit: Ideal candidates are adolescents and young adults (about 12–20 years old) experiencing a first episode of psychosis who are starting or recently started antipsychotic treatment.

Not a fit: People without a recent first episode of psychosis, those with long-standing schizophrenia, or those unwilling to have MRI or genetic testing are unlikely to benefit from joining this trial.

Why it matters

Potential benefit: If successful, the approach could help doctors choose effective medications earlier and reduce long-term disability and avoidable side effects in teens and young adults with early psychosis.

How similar studies have performed: Earlier work from the team showed that resting-state fMRI and genetic tests can predict treatment response and certain side effects, but using them in a randomized decision-support trial is new.
