Official title: Treatment Resistance in Psychiatric Disorders: the Search for Biological Markers Predictive of Response to Treatment
Run by Centre Hospitalier St Anne · NCT07741981 · Data updated 2026-11-12
This study tests whether biological markers can predict which patients with psychiatric conditions will respond to treatment.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with a DSM-5 psychiatric disorder who are starting a new treatment and have drug-resistant disease as defined by the protocol.
✕Probably not a fit
Patients who do not show the targeted biomarker profile or who do not exhibit a measurable response to treatment may not experience a benefit.

What this trial studies
This interventional study explores links between inflammation and treatment resistance across psychiatric disorders such as schizophrenia, TRD, bipolar disorder, catatonia, and OCD. It uses biological samples (blood, CSF via lumbar puncture, stool, and skin microbiopsy) alongside psychometric scales to identify markers that may predict treatment response. The goal is to understand how immune and inflammatory processes relate to how patients respond to therapies. The trial is conducted at centers in Paris, led by Centre Hospitalier St Anne with Collaboration from GHU Paris Psychiatry & Neurosciences. Participants include adults starting a new treatment and meeting DSM-5 criteria for a psychiatric disorder, with appropriate safety and consent procedures in place.
Why it matters
Potential benefit: If successful, the study could help tailor treatments based on a patient’s biomarker profile to improve response rates.
How similar studies have gone: Previous research has shown associations between inflammatory markers and treatment response in depression and other psychiatric conditions, supporting the rationale for biomarker-based prediction.
