Brief 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,
  • on attention disorders in children with epilepsy,
  • on quality of life,
  • 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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (14)

  • 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.

    12 weeks

  • Reduction of TOVA total score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.

    12 weeks

  • Proportion of subjects with a normalized TOVA score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.

    12 weeks

  • Change in quality of life score in the PS-Omega 3 group compared with the placebo group after 12 weeks of treatment.

    12 weeks

  • Evolution of plasma lipid profiles in subjects assigned to supplementation of PS-Omega 3 in comparison with the placebo group after 12 weeks of treatment.

    12 weeks

  • +9 more secondary outcomes

Study Arms (2)

PS-OMEGA 3, capsules twice daily

ACTIVE COMPARATOR

Vayarin®, supplementation of n-3 PUFA: each capsule contains 8.5 mg of docosahexaenoic acid (DHA), 21.5 mg of eicosapentaenoic acid (EPA) and 75 mg of phosphatidylserine.

Drug: Vayarin®, supplementation of n-3 PUFA

PLACEBO, capsules twice daily

PLACEBO COMPARATOR

The placebo will be made of cellulose and a small amount of fish powder to maintain the double-blind in odor and taste. The supplementation in n-3 PUFA in the placebo group may be considered as negligible. Placebo will be administered as indistinguishable capsules, identical to the active product.

Drug: PLACEBO

Interventions

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.

PS-OMEGA 3, capsules twice daily

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.

PLACEBO, capsules twice daily
