Brief Summary:
This research study is carried out to examine the effects of Phosphatidylserine-Omega 3 supplements (i.e., Vayarin) among children with Autism Spectrum Disorder (ASD) and ADHD. Participants will be randomised either to receive the Vayarin treatment (Intervention group) or to a Control group.

Condition or disease Intervention/treatment Phase
Autism Spectrum Disorder Attention Deficit Hyperactivity Disorder Dietary Supplement: Vayarin Not Applicable

Detailed Description:

There has been growing interest in the role of supplements such as omega-3 polyunsaturated fatty acids (n-3 PUFAs) in ADHD and ASD. Two of the primary n-3 PUFAs are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are critical to brain development and are usually obtained through our diets. Increasing evidence has shown that children with ASD and/or ADHD have lower overall blood n-3 PUFAs levels than typically developing children (Parletta, Niyonsenga & Duff, 2016). Therefore, many studies have been conducted to examine the effectiveness of n-3 PUFAs supplementation among these two populations. While these supplements were found to have small but reliable benefit on ADHD symptoms (Hawkey & Nigg, 2014), there is limited evidence to support the use of n-3 PUFAs in clinical practice for the treatment of behavioural symptoms in children with ASD (James, Montgomery & Williams, 2011; Roux, 2015). Such inconsistencies give rise to the exploration of other alternatives in administering n-3 PUFAs.

Phosphatidylserine (PS), an acidic phospholipid (PL) molecule, comprises of a glycerol backbone esterified to the hydroxyl group of the amino acid serine via a phosphate group and to two fatty acids moiety (Manor et al., 2012). It plays a key role in the functioning of neuron membranes and may enhance the bioavailability of PUFAs. Administration of PL containing omega-3 PUFAs showed greater improvement in visual sustained attention performance among school children with ADHD, as compared to placebo and fish oil groups (Vaisman et al., 2008). Similarly, another study also suggested the benefits of PS-Omega3 (i.e., Vayarin) in reducing ADHD symptoms (Manor et al., 2012). This supplementation is shown to be generally safe and well-tolerated (Manor et al., 2013).

Nevertheless, these studies were conducted among children with ADHD. Given that n-3 PUFAs are commonly used by children with comorbid ASD and ADHD, there is a need to examine whether similar effects can be observed in this population. The goal of our present study is to examine the effect of PS-Omega3 supplement among children with comorbid ASD and ADHD. The safety and tolerability will also be assessed in this pilot trial.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Masking Description: Clinicians conducting the study assessments and teachers who will be providing feedback will be blinded to the study arm.
Primary Purpose: Treatment
Official Title: An Open-label Pilot Study on the Efficacy of Phosphatidylserine-Omega 3 (Vayarin) in Pediatric Patients Diagnosed With Autism and Comorbid Attention Deficit Hyperactivity Disorder (ADHD)
Actual Study Start Date : November 30, 2016
Actual Primary Completion Date : December 31, 2018
Actual Study Completion Date : December 31, 2018


Arm Intervention/treatment
Experimental: Intervention
Each child participant in the Intervention group will be taking 4 capsules of Vayarin per day for 3 months. Each capsule contains 167mg Lipirinen, providing 75mg Phosphatidylserine (PS), 21.5mg EPA and 8.5mg DHA. This gives a daily dosage of 300mg PS and 120mg EPA/DHA. They may continue their treatment as usual provided there is no change in medication and intervention during the trial.
Dietary Supplement: Vayarin
Vayarin capsule
Other Name: Phosphatidylserine-omega-3 (Lipirinen)

No Intervention: Control
Participants in the Control group will not be given Vayarin. They may continue their treatment as usual provided there is no change in medication and intervention during the trial.
