Clinical Trial Summary

Our project aims to develop a new therapeutic approach in epilepsy-associated attention disorders in children, through evaluation of the clinical impact of dietary n-3 fatty acids, containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) conjugated to a phospholipid vector. The primary objective is to evaluate the efficacy of a PUFA supplementation (PS-Omega 3), after 12 weeks of treatment, on attention disorders in children with epilepsy. Secondary objectives include:

• To evaluate the impact of a supplementation of PS-Omega 3 on quality of life.

• To evaluate the impact of a supplementation of PS-Omega 3 on serum and erythrocyte lipid profiles.

• To assess the tolerance of a supplementation of PS-Omega 3.

• To assess the impact of a supplementation of PS-Omega 3 on the frequency of seizures.

• To describe the impact of a supplementation of PS-Omega 3, at 24 weeks,

1. on attention disorders in children with epilepsy,

2. on quality of life,

3. and on serum and erythrocyte lipid profiles. This study will recruit 272 subjects aged 6- 16 years, suffering from epilepsy (any type) and attention deficit hyperactivity disorder (ADHD) (inattentive or combined type) according to DSM V criteria in 12 clinical sites in France.

Two capsules will be swallowed twice daily, 20 to 30 minutes prior to breakfast and dinner, during 12 weeks, between visit 1 and visit 2. At the end of this period, active product will be continued, at the same dose, for a 12 week-open label period. All patients will be administered the active product.
• PLACEBO

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Reduction of the ADHD-rating scale IV inattentive subscore in subjects assigned to supplementation of PS-Omega 3 in comparison with the placebo group after 12 weeks of treatment.	The ADHD Rating Scale-IV quantifies each of the 18 symptoms of ADHD on a 0 to 3 scale, with a maximum score of 54 points. Nine of the 18 items score for inattention while the nine others assess hyperactivity with a maximum of 27 points each. The discriminative value of these two subscales was validated, allowing their individual use.	12 weeks
Secondary	Reduction of the ADHD Rating Scale-IV total score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.	The ADHD Rating Scale-IV quantifies each of the 18 symptoms of ADHD on a 0 to 3 scale, with a maximum score of 54 points.	12 weeks
Secondary	Reduction of TOVA total score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.	The TOVA (Test of Variables of Attention) is a computerized tool assessing the capacity of attention and impulse control. This test has been validated as a diagnostic tool in ADHD.	12 weeks
Secondary	Proportion of subjects with a normalized TOVA score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.	The TOVA (Test of Variables of Attention) is a computerized tool assessing the capacity of attention and impulse control. This test has been validated as a diagnostic tool in ADHD.	12 weeks
Secondary	Change in quality of life score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.
