Summary

Schizophrenia affects a significant proportion of the population and current levels of understanding of the illness is inadequate to treat it effectively. Converging lines of evidence suggest that neuroinflammation occurs in schizophrenia, and specifically over-activity of brain-resident immune cells called microglia. It is however unclear whether activated microglia play a primary role in schizophrenia, or whether this is a secondary phenomenon of no pathophysiological significance. The investigators therefore plan to test the effect of a monoclonal antibody (natalizumab) on psychotic symptoms in a cohort of first episode psychosis patients.

Detailed description

One of the key aims of the study is to determine if there is a relationship between change in imaging inflammation markers from baseline to follow-up and changes in other markers of inflammation over the same period. In September 2021, an open label arm for natalizumab was added to the study. The relationship between changes in imaging inflammation markers and changes in other markers of inflammation will be analysed within subjects including all patients who received natalizumab.
