研究概览
简要总结
The aim of this study is to assess the efficacy and safety of BoNT/a-DP in the treatment of glabellar lines in comparison with placebo, including efficacy after repeat treatments and long term safety.
详细描述
This multicenter Phase 3 study is comprised of two parts. The first part of the study is a randomized, double blind, placebo-controlled, phase which aims to demonstrate efficacy and safety of BoNT/A-DP compared with placebo. The second part is an open label extension phase to evaluate efficacy after repeat treatments and long term safety. Subjects can receive a maximum of four treatment cycles over the duration of the study, a single treatment in the first cycle compared with placebo, and up to three subsequent treatments in the open label extension study.

入选标准
- •Aged ≥ 18 years or older at time of screening on FWS) as determined by in-clinic assessments by both the investigator and the subject(where: 0= 'none', 1= 'mild', 2= 'moderate', 3= 'severe').
- •Subject has a stable medical condition with no uncontrolled systemic disease.
- •Female subjects of childbearing potential must test negative for pregnancy and agree to use effective birth control during the course of the study.
- •Subjects who wear glasses must be able to adequately self-assess the severity of their glabellar lines (according to the FWS), without glasses obstructing the forehead area.
- •The moderate to severe glabellar lines have an important psychological impact on the subject, as indicated by scores >0 on either the Emotional or the Social Functioning subscale of the modified Skindex-16 (GL-QoL).
排除标准
- •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).
- •Known hypersensitivity to the study medication or its excipients.
- •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.
- •Facial laser or light treatment, microdermabrasion, superficial peels or retinoid therapy within the 3 months prior to screening or planned during the study.

- •Inability to substantially lessen glabellar frown lines even by physically spreading them apart.

- •Pregnant, breastfeeding or planning to become pregnant during the trial.
- •Use of prohibited medication including anticholinergic drugs, or drugs which could interfere with neuromuscular function, including aminoglycoside antibiotics and curare-like compounds within 2 weeks prior to screening or planned during the study.

- •Participation in another clinical study within one month of screening and throughout the trial.
- •Previous participation in another botulinum toxin aesthetic study which involved the treatment of glabellar lines in combination with canthal lines and/or forehead lines in the previous 18 months.
- •Chronic drug or alcohol abuse (as per investigator discretion).
- •Eligibility Criteria for re-treatment: The following criteria MUST be met for re-treatment:
- •At time of re-treatment subject does not have relevant changes to their health status from enrollment, which would have prevented subject's entry into the study according to the inclusion and exclusion criteria
- •The subject must have been randomized to receive treatment and must have received at least one treatment (BoNT/A-DP or placebo).
- •A minimum of 12 weeks must have elapsed since the previous study treatment.
- •The subject's glabellar lines at maximum frown must have relapsed to a FWS score of 2 or 3 as determined by the investigator and the subject.
- •No relevant infection or inflammation in the planned injection area.
- •Negative urine pregnancy test, in women of child-bearing potential.
- •The subject must have received fewer than four study treatments.
- •The subject must agree and consent to re-treatment.
- •Re-treatment will be performed at the latest by week 48.

结局指标
主要结局
Facial Wrinkle Scale (FWS) Score of 0 or 1 and an Improvement of ≥ 2 Points in FWS Score (at Maximum Frown) at Week 4 Visit Relative to Baseline, Based on Both the Investigators' and the Subjects' In-clinic Assessments
时间窗: Week 4
The primary endpoint is the percentage of subjects among BoNT/A-DP and placebo groups with a Facial Wrinkle Scale (FWS) score of 0 or 1 and an improvement of ≥ 2 points in FWS score (at maximum frown) at week 4 visit (of the first treatment cycle) relative to baseline (responders), based on both the investigators' and the subjects' in-clinic assessments. Thus, the primary endpoint is a composite endpoint comprising investigator and subject assessments of treatment effectiveness. FWS scores are a four-point rating scale as follows: 0 = no facial wrinkles; 1 = mild facial wrinkles; 2 = moderate facial wrinkles; and 3 = severe facial wrinkles.
