NCT05152576
Facial lines that develop from repeated facial expression, such as forehead lines (FHL), are typically treated by selectively weakening specific muscles with small quantities of botulinum toxin. OnabotulinumtoxinA X is being investigated as another form of treatment to treat FHL by inhibiting the release of the neurotransmitter that causes the overactivity of the muscles responsible for the severity of these facial lines. The purpose of this study is to evaluate the safety and change in condition of 3 doses of OnabotulinumtoxinA X for the treatment of moderate to severe forehead lines. Study doctors will determine if a subject is eligible for the study. If so, the subject will be randomized into 1 of the 4 groups, called treatment arms. There is a 1 in 4 chance that a participant will be assigned to placebo. Around 120 adult participants with FHL will be enrolled in the study in approximately 10 sites in the United States. Participants will receive either intramuscular injections of onabotulinumtoxinA X or placebo. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular monthly visits during the study at the study site.
