Effects of oxytocin on bone health in children with autism

A Randomized, Double-blind, Placebo-controlled Study of Intranasal Oxytocin for Bone Health in Children With Autism Spectrum Disorder

Phase 2 Interventional Massachusetts General Hospital · NCT05754073

This study is testing if a nasal spray of oxytocin can help improve bone health in children with autism between the ages of 6 and 18.

What this trial studies

This randomized, double-blind, placebo-controlled study investigates the impact of intranasal oxytocin on bone health in children aged 6-18 years with autism spectrum disorder (ASD). Participants will be assigned to receive either oxytocin or a placebo for 12 months, followed by a 6-month open-label phase where all will receive oxytocin. The study will assess bone mineral density and overall bone health through various examinations, laboratory tests, and imaging techniques. The goal is to determine if oxytocin can improve bone health in this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates are children aged 6 to 18 years with a clinical diagnosis of autism spectrum disorder.

Not a fit: Patients with syndromic conditions affecting bone density or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance bone health and reduce fracture risk in children with autism spectrum disorder.

How similar studies have performed: While the approach of using oxytocin for bone health is novel, previous studies have indicated potential benefits of oxytocin in related areas.
