Trial summary

N-3 polyunsaturated fatty acids(N-3 PUFAs) is important in balancing the immune function and crucial for the developing brain. Deficiency in n-3 PUFAs might be linked to the poor cognitive performances resulting in inattention and hyperactivity in youth with attention deficit hyperactivity disorder (ADHD).

About this study

Official title: A Double-blind Randomised Controlled Trial of N-3 PUFAs in Children With Attention Deficit Hyperactivity Disorder

N-3 polyunsaturated fatty acids(N-3 PUFAs) is important in balancing the immune function and crucial for the developing brain. Deficiency in n-3 PUFAs might be linked to the poor cognitive performances resulting in inattention and hyperactivity in youth with attention deficit hyperactivity disorder (ADHD). N-3 PUFAs appears to be a promising treatment that is safe, beneficial to youth with ADHD. In this proposal, investigators aim the test the hypothesis that n-3 polyunsaturated fatty acids will be more effective than placebo in improving cognitive function in youth with ADHD after 12 weeks of intervention.

Read the detailed description

This is a 1-year study and a randomized, double-blind, and placebo controlled Clinical the study. investigators plan to enrol 100 subjects from Child and Adolescent Psychiatry Outpatient Clinic of China Medical University Hospital.Participants will be randomized into omega-3 polyunsaturated fatty acids or placebo group.The intervention period is 12 weeks. Evaluation of the cognitive function ( using Continuous Performance Test 3rd Edition ) of the subjects who are enrolled into the study will take place at baseline and after the 12th week. The symptom severity of ADHD will be measured with Swanson, Nolan, Pelham Questionnaire (SNAP-IV) at baseline, 2,4,8, and 12 weeks. The plasma level of n-3 polyunsaturated fatty acids, blood and salivary inflammatory markers will also be measured at the beginning and at the end of the study.

What is being measured

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

  1. Changes in Continuous Performance Test Raw Scores at 12 weeks

    Correct Detection: This indicates the number of times the client responded to the target stimulus. Higher rates of correct detections indicate better attentional capacity.

    Reaction times: This measures the amount of time between the presentation of the stimulus and the client's response.

    Omission errors: This indicates the number of times the target was presented, but the client did not respond/click the mouse. High omission rates indicate that the subject is either not paying attention (distractibility) to stimuli or has a sluggish response.

    Commission errors: This score indicates the number of times the client responded but no target was presented. A fast reaction time and high commission error rate points to difficulties with impulsivity. A slow reaction time with high commission and omission errors, indicates inattention in general.

    Measured: Week 0 and Week 12

Secondary outcomes (1)
  1. Changes in SNAP-IV Scores for Inattention, Hyperactivity and Total ADHD Symptom Severity

    Inattention: items 1-9 Hyperactivity: items 10-18 Total ADHD: items 1-18 the greater the scores on SNAP-IV indicate the greater the severity of ADHD symptoms

    Measured: Week 0, 2,4,8,12

Questions about this trial

What is this clinical trial studying?

A study testing n-3 Polyunsaturated fatty acid in people with Attention Deficit Hyperactivity Disorder and ADHD, run by China Medical University Hospital at 1 site in Taiwan.

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 5 inclusion and 5 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 15 Jun 2018. 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 Taiwan. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes in Continuous Performance Test Raw Scores at 12 weeks (time frame: Week 0 and Week 12). 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 NCT03542643, 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 15 Jun 2018.
