What is the purpose of this trial?

This trial explores how a treatment called Daxxify (DaxibotulinumtoxinA) can help people with facial twitching conditions like benign essential blepharospasms (BEB) and hemifacial spasms (HFS). Researchers aim to determine if Daxxify significantly reduces twitching compared to patients' experiences with Botox. Suitable participants have BEB or HFS, have not undergone surgery for these conditions, and are not taking certain neurological medications. As a Phase 4 trial, Daxxify is already FDA-approved and proven effective, and this research seeks to understand how it benefits more patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that participants should not have any known neurologic or neuromuscular systematic medications. It's best to discuss your specific medications with the trial team.

What is the safety track record for Daxxify?

Research shows that Daxxify, also known as DaxibotulinumtoxinA, is being tested for safety in treating facial twitching conditions such as benign essential blepharospasms (BEB) and hemifacial spasms (HFS). Although specific safety data for Daxxify in these conditions is not yet available, this Phase 4 study indicates that Daxxify has already demonstrated a good safety record in earlier trials and possibly in other treatments.

Similar treatments, like Botox, have been safely used for conditions like BEB over the long term, suggesting that Daxxify might also be well-tolerated. Participants should report any side effects to the study team to ensure ongoing safety monitoring. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Unlike other treatments for facial twitching, such as Botox, DaxibotulinumtoxinA, marketed as Daxxify, offers longer-lasting results. Researchers are excited because while most treatments require repeat injections every few months, Daxxify has the potential to extend the time between treatments, possibly reducing the frequency to twice a year. This durability is due to a unique peptide technology that stabilizes the botulinum toxin, providing sustained muscle relaxation.

What is the effectiveness track record for Daxxify in treating benign essential blepharospasms and hemifacial spasms?

Research has shown that DaxibotulinumtoxinA (Daxxify) effectively treats facial spasms. Studies have found it reduces symptoms in people with benign essential blepharospasms (BEB) and hemifacial spasms (HFS). Patients often experience better muscle control and less twitching. In this trial, participants with either BEB or HFS will receive Daxxify to evaluate its effectiveness for these conditions. Daxxify is already approved for treating frown lines, and its effects last longer than some other treatments. This suggests it might also provide lasting relief for facial twitching conditions like BEB and HFS. Overall, the evidence supports Daxxify as a promising option for managing these conditions. ^{1 2 3 6 7}

Published Research Related to This Trial

In a study involving 2737 patients, DaxibotulinumtoxinA-lanm (DAXI) showed a low immunogenic potential, with only 0.8% developing treatment-related nonneutralizing antibodies, which did not affect clinical efficacy.

Patients who developed transient binding antibodies still achieved a clinical response with no significant difference in treatment duration compared to those without antibodies, indicating that DAXI remains effective even in the presence of these antibodies.

Immunogenicity of DaxibotulinumtoxinA for Injection in Glabellar Lines. Humphrey, S., Dover, JS., Bowsher, RR., et al.[2023]

A total of 5,896 adverse event reports related to botulinum toxin (BTX) were analyzed from 1999 to 2016, revealing 44 safety signals, including 7 that were not previously labeled, indicating potential risks associated with BTX treatment.

The analysis showed a significantly high reporting odds ratio for 'ineffective medicine' (21.60) and 'depression' (6.02) as adverse events, particularly among females, suggesting a need for ongoing monitoring of BTX's safety profile, especially with its increasing off-label use.

In a study involving 568 adults with moderate to severe dynamic glabellar lines, repeated treatments with DaxibotulinumtoxinA (DAXI) led to a significant increase in the number of subjects showing no static glabellar lines, with improvements observed after each treatment cycle.

The results suggest that DAXI not only effectively reduces dynamic glabellar lines but also promotes long-term benefits through muscle inactivity, allowing for dermal remodeling over time.

In two phase 3 studies involving 609 subjects, DaxibotulinumtoxinA (DAXI) demonstrated significant efficacy in reducing glabellar line severity compared to placebo, with 73.6% and 74.0% of subjects showing at least a 2-point improvement at week 4.

DAXI provided a prolonged duration of effect, maintaining reduced glabellar line severity for a median of 24 weeks, and was generally well tolerated, with common side effects being mild headaches and injection-site pain.
