FDA Approves Botox Challenger Daxxify for Frown Lines

The US Food and Drug Administration (FDA) has approved daxibotulinumtoxinA-lanm  injection (Daxxify) for the temporary improvement in the appearance of moderate to severe glabellar lines (frown lines) in adults.

According to a company news release, Daxxify, an acetylcholine release inhibitor and neuromuscular blocking agent, is the first peptide-formulated, long-acting neuromodulator approved for this indication.

The approval of Daxxify, manufactured by Revance Therapeutics, was based on the data from the SAKURA phase 3 clinical trial program, which included more than 2700 adults who received roughly 4200 treatments, according to the company.

About three quarters of participants achieved at least a two-grade improvement in glabellar lines at week 4 as judged by both investigator and patient and 98% achieved “none or mild wrinkle severity” at week 4 per investigator assessment, the company said.

The median duration of treatment effect was 6 months, with some patients maintaining treatment results at 9 months, compared with a 3- to 4-month duration of treatment effect with conventional neuromodulators.

“Compelling data from the largest phase 3 clinical program ever conducted for glabellar lines demonstrated that Daxxify was well tolerated and achieved clinically significant improvement with long-lasting results and high patient satisfaction,” SAKURA investigator Jeffrey Dover, MD, co-director of SkinCare Physicians, Chestnut Hill, Massachusetts, said in the news release.

“Notably,” said Dover, “Daxxify was able to demonstrate a long duration of effect while only utilizing 0.18 ng of core active ingredient in the 40-unit labeled indication for glabellar lines.”

Daxxify has a safety profile in line with other currently available neuromodulators in the aesthetics market, the company said, with no serious treatment-related adverse events reported in clinical trial participants.

The most common treatment-related adverse events in the pivotal studies were headache (6%), eyelid ptosis (2%) and facial paresis, including facial asymmetry (1%).

Daxxify is contraindicated in adults with hypersensitivity to any botulinum toxin preparation or any of the components in the formulation and infection at the injection sites.
