Phase 0 Clinical Protocol: A Longitudinal and Multimodal Exploratory Study to Evaluate a Neuroinflammatory Hypothesis in Patients With Schizophrenia Compared to Young Healthy Subjects

Previous research has suggested central nervous system inflammatory activity to be critically involved in disease development and progression in schizophrenia, with a complex interplay of inflammatory mechanisms leading to the development of brain abnormalities and medical symptoms related to schizophrenia. However, the mutual interactions of different inflammatory pathways and their relation to disease course have not been sufficiently studied. This study therefore aims to explore the interaction of neuroinflammatory mechanisms in patients with schizophrenia and to assess whether the inflammatory activity in schizophrenia is state-dependent and occurs mainly during psychotic episodes.

Primary Outcomes

Description: Regional distribution volume in tissue (VT) of 2-(6-chloro-2-(4-(3-fluoropropoxy)phenyl)imidazo(1,2-a)pyridin-3-yl)-N,N-diethylacetamide (PBR111) labelled with fluorine-18 (18F) in schizophrenia patients and age- , gender-, and translocator protein (TSPO) binding profile- matched healthy controls

Measure: Regional VT of [18F]PBR111

Secondary Outcomes

Description: Levels and ratios of inflammatory and neurotoxicity markers in blood samples of schizophrenia patients compared to healthy age- and gender-matched healthy controls.

Measure: Peripheral markers

Time: 2 years
Time Perspective: Prospective

Case-Control
