描述
Inclusion Criteria:
- Subjects is an adult, of at least 18 years of age
- Subject is able to provide informed consent and comply with study instructions
- Subject has moderate to severe glabellar lines at maximum frown as assessed by the investigator using the GLS
- Subject has moderate to severe glabellar lines at maximum frown as assessed by the subject using the GLS
- Subject is willing and able to complete the entire course of the study
Exclusion Criteria:
- Previous treatment with botulinum toxin of any serotype in any area within the last 6 months
- Previous treatment with any facial aesthetic procedure (e.g. injection with fillers, chemical peeling, photo rejuvenation) in the glabellar area within the last 12 months
- Previous insertion of permanent material in the glabellar area
- Planned treatment with botulinum toxin of any serotype in any other body region during the study period
- Any surgery in the glabellar area including surgical removal of the corrugator, procerus, or depressor supercilii muscles or a combination of these, or scars in the glabellar area and the surrounding areas (including eye brow)
- Energy-based or cryo-therapy based treatment of facial muscles superior to the lateral canthus
- Any other planned facial aesthetic procedure during the trial period, superior to the level of the lateral canthus (subjects can continue with their usual skin care routine)
- Subjects who may not respond to 20 Units of botulinum toxin (e.g., inability to substantially lessen glabellar frown lines even by physically spreading them apart)
- Marked facial asymmetry
- Ptosis of eyelid and/or eyebrow, or history of eyelid and/or eyebrow ptosis
- History of facial nerve palsy
- Excessive dermatochalasis, deep dermal scarring, thick sebaceous skin
- Any active infection in the area of the injection sites
- Medical condition that may affect neuromuscular function (e.g., myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis)
- Evidence of recent alcohol or drug abuse
- Medical or psychiatric conditions that may increase the risk associated with study participation or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study
- Pregnant or sexually active female subjects who are of childbearing potential and who are not willing to use an acceptable form of contraception
- Known allergy or hypersensitivity to botulinum toxin preparation
- Participation in another interventional clinical study within the last 30 days

由研究者和受试者独立评估的 Glabellar Line Scale (GLS) 改善≥2 点的参与者百分比
大体时间:第 30 天
|
主要疗效终点评估 DWP-450 在第 30 天相对于安慰剂的有效性。 主要疗效指标是复合终点。 使用 GLS 量表,研究人员和受试者将在第 0 天和第 30 天评估眉间线。 仅当研究者和受试者都独立同意从第 0 天到第 30 天出现 ≥ 2 的改善时,受试者才是反应者。 GLS 评分:0=无,1=轻度,2=中度,3=重度。 |

次要终点是在第 120 天被归类为反应者的受试者比例。 这是一个复合终点,基于研究者和受试者对 GLS 上最大皱眉时眉间线的评估;仅当研究者和受试者都独立同意从第 0 天到第 120 天发生了 ≥ 2 分的改善时,受试者才是反应者 GLS 评分:0=无,1=轻度,2=中度,3=重度。 |

次要终点是在第 150 天被归类为反应者的受试者比例。 这是一个复合终点,基于研究者和受试者对 GLS 上最大皱眉时眉间线的评估;仅当研究者和受试者都独立同意从第 0 天到第 150 天出现≥2 分的改善时,受试者才是反应者 GLS 评分:0=无,1=轻度,2=中度,3=重度。 |

Percentage of Participants With a ≥2 Point Improvement in Glabellar Line Scale (GLS) as Independently Assessed by Investigator and and Subject
大体时间:90 Days
|
Secondary endpoint was the proportion of subjects classified as responders on Day 90. This was a composite endpoint based on both the Investigator and subject assessments of glabellar lines at maximum frown on the GLS; a subject was a responder only if both the Investigator and subject independently agreed that a ≥2 point improvement had occurred from Day 0 to 90 Day. GLS is scored: 0=none, 1=mild, 2=moderate, 3=severe. |
