简要总结
In this study, eligible subjects with moderate to severe nasolabial folds will be treated with Princess® FILLER Lidocaine and will return for follow-up assessments 2, 4, 24 and 36 weeks after the treatment. A Touch-up treatment may be done at Week 2, if deemed appropriate by the investigator
详细描述
A prospective, open label, multicenter, post-market investigation. Following informed consent and screening, eligible subjects with moderate to severe nasolabial folds were treated with Princess® FILLER Lidocaine, and were to return for follow-up assessments 2, 4, 24 and 36 weeks after the initial treatment. A Touch-up treatment may be done at Week 2 after initial treatment, if deemed appropriate by the investigator. The performance of the investigational device evaluated by the investigator by assessing severity of nasolabial folds using the Nasolabial Folds Severity Rating Scale (NLF-SRS) (4, 24 and 36 weeks after the initial treatment and in comparison to Day 0) and global aesthetic improvement (4, 24 and 36 weeks after the initial treatment). The subject evaluated pain intensity associated with the treatment (at Day 0 and at Week 2 after initial treatment (if Touch-up treatment occurred)), and satisfaction with the treatment 4, 24 and 36 weeks after the initial treatment.
The safety was evaluated based on occurrence of adverse events, which were collected throughout the investigation.

结局指标
主要结局
Change From Baseline in Average Nasolabial Folds-Severity Rating Scale (NLF-SRS) Grade Based on Investigator Assessment at Week 24
时间窗: Baseline and Week 24
Change from baseline in average Nasolabial Folds-Severity Rating Scale (NLF-SRS) grade based on investigator assessment at week 24 after the initial treatment. The left and right nasolabial folds were graded separately on the 5-point NLF-SRS then the average of the two sides was used for analysis. NLF-SRS scores are ranked as 0 (None/minimal), 1 (Mild), 2 (Moderate), 3 (Severe) and 4 (Extreme).
Proportion of Subjects With ≥1 Point Reduction in Nasolabial Folds-Severity Rating Scale (NLF-SRS) Grade Based on Investigator Assessment at Week 24
时间窗: Week 24
The proportion of subjects with at least 1 point reduction from baseline in Nasolabial Folds-Severity Rating Scale (NLF-SRS) grade based on investigator assessment at week 24 after the initial treatment. The left and right nasolabial folds were graded separately. A subject is counted if the subject had at least one grade reduction over baseline on both nasolabial folds, on the 5-point NLF-SRS. NLF-SRS scores are ranked as 0 (None/minimal), 1 (Mild), 2 (Moderate), 3 (Severe) and 4 (Extreme).

- Satisfaction of Subjects With Aesthetic Outcome at Weeks 4, 24 and 36(Week 4, Week 24, Week 36)
- Average Pain Intensity Based on Subject Assessment Immediately After the Last Injection and 15 Minutes Thereafter for Initial and Touch-up Treatment(Baseline - Immediately after end of treatment, 15 minutes after end of treatment Week 2 - Immediately after end of treatment, 15 minutes after end of treatment)
- Proportion of Subjects With Aesthetic Improvement Based on Investigator Assessment at Weeks 4, 24 and 36(Week 4, Week 24, Week 36)
- Proportion of Subjects With ≥1 Point Reduction in Nasolabial Folds-Severity Rating Scale (NLF-SRS) Grade Based on Independent Reviewer Assessment of Photographs at Week 24(Week 24)
