Outcome Measures
Primary Outcomes (1)
Change From Baseline on the MAPS-D Score at Maximum Contraction as Assessed by the Investigator at Visit 4 (V4)
The platysma area will be assessed live by the investigator at maximum contraction and graded according to the validated five-point Merz Aesthetic Platysma Scale-Dynamic (MAPS-D). Scores range from Grade 1 (none to minimal) to Grade 5 (very severe).
Baseline (Screening Visit), Week 2 (V4)
Secondary Outcomes (2)
Change From Baseline on the MAPS-D Score at Maximum Contraction as Assessed by the Subject at V4
Baseline (Screening Visit), Week 2 (V4)

Interventions
Clostridium botulinum neurotoxin type A (150 kiloDalton \[kD\], free of complexing proteins) powder for solution for injection.
Eligibility Criteria
You may qualify if:
- Presence of four (medial and lateral, left and right) prominent platysmal bands
- Moderate to severe platysmal bands as assessed by the investigator and subject on the MAPS-D at maximum contraction
You may not qualify if:
- Any serious disease or disorder (medical or psychiatric) that could interfere with the safe completion of treatment or compromise subject safety
- Botulinum toxin treatment in the face (below the lower orbital rim), neck, or chest within the last 12 months prior to study treatment
- History of lower face surgery, neck or chest surgery, aesthetic procedures (e.g., ablative skin resurfacing, laser, chemical peel, micro-focused ultrasound, deoxycholic acid injections, micro-needling, non-surgical fat reduction procedure), and orthodontic procedures (e.g., braces) in the 12 months prior to study treatment
- Previous use of any permanent (non-biodegradable) or semi-permanent (e.g., calcium hydroxylapatite, poly-L-lactic acid, polymethyl methacrylate, etc.) facial tissue augmentation therapy, lifting sutures, permanent implants or autologous fat to the lower face (i.e., below the level of the bottom of the nose), neck, or chest within 24 months prior to study treatment
- Previous use of any hyaluronic acid based or collagen based biodegradable facial tissue augmentation therapy to the lower face (i.e., below the level of the bottom of the nose), neck, or chest within 12 months prior to study treatment
- Any medical condition that may put the subject at increased risk with exposure to botulinum toxin of any serotype, including myasthenia gravis, Lambert-Eaton-Syndrome, amyotrophic lateral sclerosis, or any other disorder that might interfere with neuromuscular function
- Female of childbearing potential not using a highly effective method of birth control, planning to get pregnant, or pregnant or lactating
