Folinic acid improves the score of Autism in the EFFET placebo-controlled randomized trial

Abstract

Autism spectrum disorders (ASD) are influenced by interacting maternal and environmental risk factors. High-dose folinic acid has shown improvement in verbal communication in ASD children. The EFFET randomized placebo-controlled trial (NCT02551380) aimed to evaluate the efficacy of folinic acid (FOLINORAL®) at a lower dose of 5 mg twice daily.Nineteen children were included in the EFFET trial. The primary efficacy outcome was improvement of Autism Diagnostic Observation Schedule (ADOS) score. The secondary outcomes were the improvement in ADOS sub scores communication, social interactions, Social Responsiveness Score (SRS) and treatment safety.The global ADOS score and social interaction and communication sub scores were significantly improved at week 12 compared to baseline in the folinic acid group (P = 0.003, P = 0.004 and P = 0.022, respectively), but not in the placebo group (P = 0.574, P = 0.780, P = 0.269, respectively). We observed a greater change of ADOS global score (−2.78 vs. −0.4 points) and (−1.78 vs. 0.20 points) in the folinic acid group, compared to the placebo group. No serious adverse events were observed.This pilot study showed significant efficacy of folinic acid with an oral formulation that is readily available. It opens a perspective of therapeutic intervention with folinic acid but needs to be confirmed by a multi-center trial on a larger number of children.
