Abstract
Objective PrabotulinumtoxinA-xvfs (Jeuveau), a botulinum toxin type A, was approved by the Food and Drug Administration for the temporary improvement in the appearance of moderate-to-severe glabellar lines in February 2019. This article will review phase II and III clinical trials to assess the efficacy, safety, and clinical application of this novel, aesthetic-only drug. Data sources A systematic literature review was performed using the terms “glabellar lines AND prabotulinumtoxinA” in the PubMed database. ClinicalTrials.gov was searched to identify nonpublished studies. Study Selection and Data Extraction Articles written in English between November 2019 and June 2020 discussing phase II and phase III clinical trials were evaluated. Data Synthesis By the primary efficacy end point on day 30, more patients achieved a greater than 2-point improvement on the Glabellar Line Scale (GLS) at maximum frown compared with baseline on day 0. The proportions of participants who responded to treatment with prabotulinumtoxinA were 67.5% and 70.4% versus 1.2% and 1.3% in placebo groups across 2 identical clinical trials ( P < 0.001). Patients receiving prabotulinumtoxinA experienced greater improvement in GLS at maximum frown on day 30 (87.2%) compared with onabotulinumtoxinA (82.8%) and placebo (4.2%; P < 0.001). PrabotulinumtoxinA was well tolerated across all studies. Relevance to Patient Care and Clinical Practice This review provides a detailed analysis of the safety and efficacy of prabotulinumtoxinA-xvfs and includes special considerations to help guide patients and clinicians. Conclusion PrabotulinumtoxinA is a safe and effective new addition to the repository of available treatments for the appearance of glabellar lines.
