  Purpose

The overall goal of the present study is to determine whether Omega-3 Fatty Acids potentially prevent onset of psychosis and improve clinical symptoms and functional outcome in youth and young adults at elevated clinical risk for schizophrenia and related disorders. The specific aims are: (1) To determine whether the rate of progression to psychosis is lower during six months of treatment with Omega-3 Fatty Acids compared to six months of treatment with placebo, (2) To determine whether Omega-3 Fatty Acids are more efficacious than placebo for prodromal symptoms, negative symptoms, and functioning, (3) To assess the safety and tolerability of Omega-3 Fatty Acids in this population, and (4) To conduct analyses of neuroimaging, neurocognitive, electrophysiological and other ancillary data to explore mechanistic explanations for the hypothesized benefits of Omega-3 Fatty Acids on clinical and functional outcomes (e.g., increases in white matter integrity and processing speed).

Primary Outcome Measures:
  • rate of conversion to psychosis [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    The rate of conversion to psychosis among prodromal patients assigned at random to Omega-3 Fatty Acids at 12 months will be significantly lower than that among patients assigned to placebo.


Secondary Outcome Measures:
  • Scale of Prodromal Symptoms (SOPS) total score (indexing severity of positive, negative, and general symptoms) [ Time Frame: 6 months and 12 months ] [ Designated as safety issue: No ]
    The reduction from baseline in the Scale of Prodromal Symptoms (SOPS) total score (indexing severity of positive, negative, and general symptoms) at 6 and 12 months will be significantly greater in prodromal patients assigned at random to Omega-3 Fatty Acids than in patients assigned to placebo.


Estimated Enrollment: 128
Study Start Date: August 2011
Estimated Study Completion Date: April 2014
Estimated Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Soybean-Corn Blend Capsule
The placebo is a soybean/corn blend. Both the Omega-3FA and placebo are colored with carob (so shell is brown) and flavored with natural lemon-lime, to mask them.
Drug: Placebo
The placebo is a soybean/corn blend. Both the Omega-3FA and placebo are colored with carob (so shell is brown) and flavored with natural lemon-lime, to mask them. The dose will be 2 capsules per day.
Other Name: Placebo
Experimental: Omega 3 long chain fatty acid
The Omega-3 Fatty Acid compound will be manufactured by Ocean Nutrition Canada and contain an 2:1 proportion of EPA to DHA in which each capsule includes 370 mg EPA and 200 mg DHA as well as 2 mg/g Tocopherol. The dose will be two capsules per day for a total of 740 mg of EPA and 400 mg of DHA.
