Placebo-Controlled Study of Terpenes-Enriched Cannabis Oil T1/C28 for Children With Autism

Официальное название

A Phase 2, Placebo-Controlled, Randomized, Double-Blind Study to Assess the Safety, Tolerability and Efficacy of Terpenes-enriched Cannabis Oil T1/C28, Administered to Pediatric Subjects With Autism Spectrum Disorder (ASD)

Обзор

The goal of this clinical trial is to determine whether cannabidiol (CBD, 28%) combined with terpenes and a small amount of THC (1%) can help reduce symptoms of autism, and to evaluate the safety of this treatment. The main questions are: 1. Does this treatment improve behavioral challenges in children with autism? 2. Does this treatment improve social difficulties in children with autism? What will happen in the study: 1. Participants take either the study treatment or a placebo (a look-alike substance with no active drug) every day for 2 months. 2. After 2 months, all participants receive the study treatment or a similar treatment without THC for another 2 months. 3. Participants come to the clinic once every 2 months for checkups and tests.

Подробное описание

Autism spectrum disorder (ASD) is a condition that affects communication, social interaction, and behavior. Current medications do not treat the core symptoms of autism, and the drugs sometimes prescribed (such as antipsychotics for irritability) can cause significant side effects.

Cannabidiol (CBD) is a natural, non-psychoactive compound from the cannabis plant that may reduce brain overactivity and inflammation. Tetrahydrocannabinol (THC), the psychoactive component of cannabis, acts on the endocannabinoid system, which is thought to function differently in people with autism. Research suggests that CBD combined with very small amounts of THC may improve behavior and social functioning. Other plant compounds called terpenes may enhance the effects of CBD and THC, even at low doses.

This study tests whether a CBD oil enriched with terpenes and a very small amount of THC is safe and effective for children with autism. Seventy-eight children, ages 4-13, will participate. Half will receive the study oil and half will receive a placebo (an inactive oil that looks the same) for 8 weeks. Afterward, all participants will receive an active treatment for another 8 weeks.

The study evaluates whether the treatment improves behavior, social skills, and quality of life. Safety is monitored through regular clinic visits, questionnaires, physical exams, and blood tests.
