What this trial studies

Paediatric Autism Communication Therapy (PACT) is designed to reduce symptoms of autism in children aged 2-6 years who have recently been diagnosed with Autism Spectrum Disorder (ASD). This trial will compare the effects of PACT combined with standard management to standard management alone. It aims to evaluate both the beneficial and harmful effects of this intervention in a pragmatic, randomized clinical trial format. The study is independently funded and conducted across multiple centers in Denmark.

Why it matters

Potential benefit: If successful, this therapy could significantly reduce autism symptoms in young children, improving their communication skills and overall quality of life.

How similar studies have gone: Other studies have shown promising results with similar naturalistic developmental behavioral interventions for autism, indicating potential for success in this approach.
