What this trial studies

This clinical trial aims to evaluate the effects of DaxibotulinumtoxinA-Lanm (Daxxify) in patients suffering from benign essential blepharospasm (BEB) and hemifacial spasm (HFS). It employs a single-arm, crossover design where participants previously treated with Botox will switch to Daxxify, allowing for a direct comparison of efficacy using their own historical data. The study will assess the clinical response through the Jankovic Rating Scale (JRS) and monitor immediate effects within 48-72 hours post-treatment. Adverse effects will also be documented to ensure patient safety.

Why it matters

Potential benefit: If successful, this treatment could provide significant relief from spasms for patients with BEB and HFS, improving their quality of life.

How similar studies have gone: Previous studies have shown positive outcomes with botulinum toxin treatments for similar conditions, suggesting potential success for this novel approach with DaxibotulinumtoxinA.
