The Food and Drug Administration (FDA) has approved letibotulinumtoxinA-wlbg, an injectable neurotoxin long used in South Korea for the treatment of moderate to severe glabellar (frown) lines in adults. Developed by Hugel, the product is being marketed under the brand name Letybo.
The FDA’s approval was based on positive results from three phase 3 trials of letibotulinumtoxinA-wlbg that enrolled more than 1000 individuals in the United States and Europe. According to information in the package insert, the most common adverse reaction reported in the trials was headache, which occurred in 2% of trial participants. Other adverse events reported by fewer than 1% of trial participants included brow ptosis, eyelid ptosis, and blepharospasm, while the most frequently reported injection site reactions included administrative site swelling, facial pain, folliculitis, and periorbital hematoma.
According to a press release from the company, letibotulinumtoxinA-wlbg has been the leading neurotoxin brand in South Korea for 7 consecutive years, and the product has been sold in more than 50 different countries. Hugel plans to launch Letybo for US-based aesthetic clinicians in the latter half of 2024.
