Primary | 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 | Change From Baseline on the MAPS-D Score at Maximum Contraction as Assessed by the Subject at V4 | The platysma area will be assessed by the subjects at maximum contraction and graded according to the validated five-point MAPS-D. Scores range from Grade 1 (none to minimal) to Grade 5 (very severe). | Baseline (Screening Visit), Week 2 (V4) | |
Secondary | Number of Subjects With Related Treatment Emergent Adverse Events (Related TEAEs) | TEAEs are defined as adverse events (AEs) with onset or worsening on or after date and time of first dose of study treatment. An AE is considered to be related if a causal relationship between NT 201 and the AE is at least reasonably possible. | Baseline up to Week 17/End of Study |
