Official title

18F-Dihydroxyphenylalanine (DOPA) Positron Emission Tomography (PET), Randomized, Double-blind, Crossover Study to Explore Dopamine Synthesis Capacity in the Whole Striatum After 2 Weeks of Treatment With 150mg of RO6889450 or Placebo in Patients With Schizophrenia

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is an exploratory proof of mechanism (POM) study using PET/functional magnetic resonance imaging (fMRI) in a 2-period, 2-sequence, crossover design. The aim of the study is to confirm the potential of Ralmitaront to decrease dopamine synthesis capacity (DSC) - as measured by levels of F-DOPA - in the striatum of participants with schizophrenia.
