About this study

Official title: Detecting Which Patients With Schizophrenia Will Improve With Omega-3 Treatment

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

Read the detailed 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RisperidoneDrug

    Also called Risperdal

    The dosage for risperidone will be 1 mg to 6 mg per day. The dose of the risperidone will be based on the participant's clinical improvement and side effects.

  • Omega-3 capsulesDrug

    Also called Omega-3

    The total daily dose for omega-3 subjects will be 740 mg of eicosapentanoic acid (EPA)and 400 mg of docosahexaenoic acid(DHA). This dose will start on day 1 and stay the same dose until study completion.

  • PlaceboDrug

    Also called Placebo capsules

    The total daily dose for subjects assigned to placebo will be 2000 mg. This dose will start on day 1 and stay the same dose until study completion.

Study groups in NCT01786239
Study groupRoleWhat they receive
Omega-3 capsules & RisperidoneExperimentalSubjects will take 1 capsule in the morning and 1 capsule in the evening. Each capsule contains 370 mg EPA and 200 mg DHA as well as 2 mg/g tocopherol. The study dose will start on day 1 and remain the same throughout the study.
Receives: Drug: Risperidone; Drug: Omega-3 capsules
Placebo & RisperidoneOtherSubjects will take 1 capsule in the morning and 1 capsule in the evening.The placebo is a soybean/corn blend (each capsule contains 1000 mg). The study dose will start on day 1 and remain the same throughout the study.
Receives: Drug: Risperidone; Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Treatment Response

    The primary outcome measure will be the total Brief Psychiatric Rating Scale Score. The range of the BPRS is 0 to 126 with higher scores indicated more psychological symptoms.

    Measured: 16 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Risperidone and Omega-3 capsules in people with Schizophrenia and Schizophreniform Disorder, run by Delbert Robinson at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Feb 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment Response (time frame: 16 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01786239, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2017.
