Omega-3 Dietary Supplements in Schizophrenia

Status Completed

Clinical Trial Summary

This 16-week placebo-control study looks to investigate whether patients with schizophrenia for two years or less may benefit from omega-3 supplements.

Clinical Trial Description

This study looks to investigate whether patients with schizophrenia for 2 years or less may benefit from omega-3 supplements. The main hypothesis to be tested in this study is that white matter integrity assessed with diffusion tensor imaging (DTI) and erythrocyte membrane omega-3 concentration may provide the means for identifying patients most likely to derive clinical benefit from omega-3 supplementation.

To test this hypothesis the investigators will enroll 58 patients with recent-onset schizophrenia into a 16-week long randomized double blind placebo-controlled study of risperidone versus risperidone plus omega-3 supplementation. Study assessments after consent will include a baseline MRI and an MRI at the final visit, blood-work, clinical interviews to assess symptoms, and medical assessments for side effects. DTI exams and peripheral omega-3 concentration will be obtained prior to the initiation of treatment and the primary outcome measure will be the total Brief Psychiatric Rating Scale Score.

Specific aims are:

- To examine the efficacy of omega-3 fatty acids as an adjuvant agent in the treatment of patients with recent-onset schizophrenia. The investigators hypothesize that patients treated with omega-3 fatty acids will demonstrate greater Brief Psychiatric Rating Scale (BPRS) reductions compared to the placebo group.

- To identify whether pre-treatment fractional anisotropy (FA) assessed by DTI predicts which patients will derive clinical benefit from omega-3 fatty acids. The investigators hypothesize that patients with lower fractional anisotropy will derive greater clinical benefit from omega-3 fatty acid supplementation.

- To identify whether pre-treatment peripheral omega-3 fatty acid concentrations predict which patients will derive clinical benefit from omega-3 fatty acids. The investigators hypothesize that patients with lower peripheral omega-3 fatty acid concentrations will derive greater clinical benefit from omega-3 fatty acid supplementation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
