Adults at least 18 years old with moderate or severe Glabellar Lines (GL) at maximum frown, assessed by using the Facial Wrinkle Scale (FWS), may qualify for this clinical research trial. These wrinkles between the eyebrows are ones that develop from repeated facial expression. Qualified individuals must not have received treatment with any botulinum neurotoxin for aesthetic treatment within the last 6 months, and for therapeutic treatment within the last 12 months.
Participants will receive investigational medication (active study drug) or placebo via injection. Study medication and study-related care will be provided at no cost to you.
Study participation will last about 14 weeks and involve about 24 visits to the study centre.
