Abstract
DAXXIFYTM (daxibotulinumtoxinA-lanm) for intramuscular injection was recently approved for temporary improvement in the appearance of the moderate to severe glabellar lines (GLs) associated with corrugator and/or procerus muscle activity in adult patients. DaxibotulinumtoxinA for Injection (DAXI) includes a purified 150-kDA botulinum toxin Type A (BoNTA) formulated with a novel peptide excipient that is positively charged and helps to bind the neurotoxin to negatively charged neuronal membrane for a longer duration. The effectiveness of DAXI was evaluated in two phase 3 trials, SAKURA 1 and SAKURA 2, using a randomized, double-blind, placebo-controlled design. The primary endpoint (treatment success) was a composite clinical outcome (investigator and subjects) of ≥2-point improvement in severity of GLs at week 4. In SAKURA 1, the treatment success was 74% (148/201) in subjects treated with DAXI and 0% in subjects treated with placebo. In SAKURA 2, the treatment success was 74% (152/205) in subjects treated with DAXI and 0% in subjects treated with placebo. An open-label study, SAKURA 3, included 2,691 participants, who underwent three consecutive treatment cycles. These individuals were recruited from either SAKURA 1 or SAKURA 2 trials, or were new to the study and received DAXI. Treatment success proportions were 73.2%, 77.7%, and 79.6% across the three consecutive treatment cycles. The recommended dose is 40 units for the Glabellar-complex divided in traditional five intramuscular injections at five injection sites (medial and lateral corrugator bilaterally and one injection in the procerus muscle).
