This is a phase 2a, multicenter, open-label, dose-escalation study to evaluate treatment of moderate or severe dynamic forehead lines (FHL) (frontalis) in conjunction with treatment of the glabellar complex.

Inclusion Criteria:

• Be outpatient, male or female subjects, in good general health, 18-65 years of age
• Have a score of moderate (2) or severe (3) FHL during maximum contraction (eyebrow elevation) as assessed by the Investigator Global Assessment Forehead Wrinkle Severity (IGA-FHWS)
• Have a score of moderate (2) or severe (3) FHL during maximum contraction (eyebrow elevation) as assessed by the Patient Forehead Wrinkle Severity (PFHWS)
• Have a score of moderate (2) or severe (3) GL during maximum frown based on the Investigator Global Assessment Frown Wrinkle Severity (IGA-FWS) scale
• Have a score of moderate (2) or severe (3) on GL during maximum frown as assessed by the Patient Frown Wrinkle Severity (PFWS)
• Be willing to refrain from receiving facial fillers, laser treatments, use of any product that affects skin remodeling, or a product that may cause an active dermal response in the treatment areas (e.g., above the inferior orbital rim) from screening through the end of the study
• Able to understand the requirements of the study and be willing and able to follow all study procedures, attend all scheduled visits, and successfully complete the study.

Exclusion Criteria:

• Active skin disease, infections, or inflammation at the injection sites
• Plans to receive botulinum toxin type A anywhere in the face (other than study treatment) from screening through the end of the study
• History of clinically significant bleeding disorders
• Non-ablative laser or light treatments, microdermabrasion, or chemical peels (medium depth or deeper, for example trichloroacetic acid (TCA) or phenol) in the treatment areas within 3 months before enrollment through the end of the study
• Clinically significant laboratory values at screening that may interfere with a subject's ability to complete the study as determined by the investigator
• History of upper or lower lid blepharoplasty or brow lift
• Prior periorbital or forehead surgery

Intent to treat population

The adverse events were collected throughout the entire study, up to 36 weeks after FHL treatment (total of 38 weeks).

The Safety Population includes all subjects who received at least 1 study treatment injection and was used to assess AEs and SAEs
