Eligibility

Inclusion Criteria:

• Aged = 18 years or older at time of screening

• Has moderate to severe glabellar frown lines at maximum frown (severity score of 2 or 3 on FWS) as determined by in-clinic assessments by both the investigator and the subject(where: 0= 'none', 1= 'mild', 2= 'moderate', 3= 'severe').

• 18 years of age

Exclusion Criteria:

• Any medical condition that may place the subject at increased risk due to exposure to botulinum toxin, including diagnosed myasthenia gravis, Eaton Lambert syndrome, amyotrophic lateral sclerosis, profound atrophy or weakness in the target muscles, or any other condition (at the investigator's discretion) that might interfere with neuromuscular function or contraindicate botulinum toxin therapy.

• Previous treatment with any serotype of botulinum toxin for any indication within the 12 months prior to screening, or any planned treatment with botulinum toxin of any serotype for any reason during the trial (other than the investigational treatment).

• Active skin disease/infection or irritation at the treatment area

• Pregnant, breastfeeding or planning to become pregnant during the trial.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Safety Evaluation	Frequency, severity and causal relationship of AEs, SAEs and AESIs	Through study completion (60 weeks)
Primary	Responder Rate at Week 4	Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement =2 points in FWS score (at maximum frown) at the week 4 visit relative to baseline, based on both the investigator's and the subject's in-clinic assessment	week 4 relative to baseline
Secondary	Percentage of responders at maximum frown at week 12	Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement =2 points in FWS score (at maximum frown) at the week 12 visit relative to baseline, based on both the investigator's and the subject's in-clinic assessment	week 12
Secondary	Percentage of responders at week 16	Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement =2 points in FWS score (at maximum frown) at the week 16 visit relative to baseline, based on both the investigator's and the subject's in-clinic assessment	week 16
Secondary	Subjects with a = 1 point reduction in FWS score	Proportion of subjects with a = 1 point reduction in FWS score at rest at week 4, based separately on the investigators' and the subjects' in-clinic assessments	week 4
Secondary	Percentage of responders at week 20 or later	Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement =2 points in FWS score (at maximum frown) at the week 20 visit (or later) relative to baseline, based on both the investigator's and the subject's in-clinic assessment	week 20
