Trial Summary

Will I have to stop taking my current medications?

The trial requires that your current medications be stable for at least 4 weeks before starting and throughout the study, so you should not stop taking them if they are stable.

What data supports the effectiveness of the drug CBDV for Prader-Willi Syndrome?

Research shows that CBDV, a compound similar to CBD, has been beneficial in improving neurological and social deficits in conditions like Rett syndrome, which shares some symptoms with Prader-Willi Syndrome. This suggests potential benefits of CBDV for Prader-Willi Syndrome, although direct evidence is not yet available.12345

Is CBDV safe for humans?

CBDV has been studied for safety in conditions like Rett syndrome and epilepsy, showing it is generally well-tolerated in humans, including children, without causing hallucinations.12346

How does the drug CBDV differ from other treatments for Prader-Willi Syndrome?

CBDV is unique because it is a non-psychotropic compound derived from Cannabis sativa, which means it doesn't cause the 'high' associated with cannabis. It has shown potential in treating neurological conditions like epilepsy and autism spectrum disorders by interacting with specific receptors in the brain, which may offer a novel approach for managing symptoms of Prader-Willi Syndrome.12357

What is the purpose of this trial?

This study tests if a safe cannabis compound that doesn't cause a high can help reduce irritability in children and young adults with Prader-Willi Syndrome.

Findings from Research

In a study involving 34 children aged 4-10 with Dravet syndrome, purified cannabidiol (CBD) was found to be generally well-tolerated, with a dose-proportional increase in exposure to CBD and its metabolites, indicating effective pharmacokinetics.
While CBD treatment resulted in more adverse events (AEs) compared to placebo, such as pyrexia and sedation, no significant safety concerns were identified, and all patients recovered from any elevated liver enzymes without meeting criteria for drug-induced liver injury.

Cannabidivarin (CBDV), a non-psychotomimetic cannabinoid, is gaining attention for its potential therapeutic effects in managing neurological conditions, particularly epilepsy and autism spectrum disorder.
This review compiles both animal and human studies to provide a comprehensive overview of CBDV's therapeutic potential, highlighting its promise as a treatment option alongside the more widely studied cannabidiol (CBD).
Therapeutic potential of cannabidivarin for epilepsy and autism spectrum disorder.Zamberletti, E., Rubino, T., Parolaro, D.[2022]
This systematic review analyzed nine randomized controlled trials (RCTs) on the use of cannabidiol (CBD) for neurodevelopmental disorders, revealing inconsistent evidence for its efficacy, which makes it difficult to recommend for clinical use.
While some studies suggest potential benefits of CBD for conditions like ADHD and autism, the overall variability in study design and outcomes indicates that more rigorous research is needed to establish its safety and effectiveness as a treatment.
