In clinical practice, different upper facial areas are commonly treated together.
To evaluate the efficacy and safety of repeated incobotulinumtoxinA injections for the treatment of upper facial lines (UFL) in a 3-month open-label extension (OLEX) period.
In the main study period (randomized, double blind, placebo controlled; n = 156), subjects with moderate-to-severe UFL (glabellar frown lines [GFL], horizontal forehead lines [HFL], and lateral periorbital lines [LPL]) on the 5-point Merz Aesthetics Scales (MAS) received 54 to 64 U incobotulinumtoxinA or placebo. In the OLEX, all subjects (n = 139) received 1 treatment with 54 to 64 U incobotulinumtoxinA. Investigator- and subject-assessed MAS scores were evaluated at rest and maximum contraction. Response was defined either as a MAS score of “none” or “mild” or a ≥1-point improvement in MAS scores.
A clear, rapid treatment response was seen in each individual treated area and for all areas combined. At Day 30, a response of none or mild at maximum contraction (investigator's rating) was reported for 80.1%, 77.2%, and 66.9% of subjects for GFL, HFL, and LPL, respectively. IncobotulinumtoxinA was well tolerated, with no evidence of an increase in adverse events with repeat injection.
IncobotulinumtoxinA is highly effective for the simultaneous treatment of UFL with a good safety profile (EudraCT Number: 2011-005887-20).
