What this trial studies

This study aims to evaluate the effects of oral Ultramicronized-Palmitoylethanolamide (PEA) on alleviating anxiety and depressive symptoms in individuals with Level 1 Autism Spectrum Disorder (ASD). It will assess the safety, tolerability, and biological mechanisms of PEA over a 12-week treatment period. The study will recruit eligible participants aged 18-35 who can communicate in Italian and provide informed consent. The focus is on addressing the unmet clinical needs of autistic individuals who do not respond well to conventional treatments.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 18-35 diagnosed with Level 1 ASD who experience comorbid anxiety and/or depressive symptoms.

Not a fit: Patients with Level 2 or Level 3 ASD or those with major psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option for managing anxiety and depressive symptoms in autistic individuals.

How similar studies have performed: While the therapeutic potential of endocannabinoid modulation is gaining interest, this specific approach using PEA in this population is relatively novel and has not been extensively tested.
