简要总结
The aim of this interventional, pre-market, double- blinded, controlled, two stages study is to evaluate the performance and safety of Crosslinked Hyaluronic Acid (CLHA) Hydrogel (with and without Lidocaine) for the Treatment of Soft Tissue Deficits.
详细描述
The performance of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine), for the correction of congenital and acquired deficits of soft tissue, will be evaluated using the change from baseline to V3 in the Wrinkle Severity Rating Scale (WSRS) for 26 mg/ml and 18mg/ml CLHA formulations and in the Lip Fullness Scale (LFS) for 20 mg/ml CLHA formulation.
The duration of the aesthetic effect of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine) for the correction of NLFs, perioral wrinkles and lips augmentation, will be assessed using the mean of the absolute change from baseline to each follow up visit in WSRS and LFS score. WSRS and LFS will be assessed by the evaluating investigator who will be different by the treating investigator.
The aesthetic appearance of the Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine) will be assessed using the Global Aesthetic Improvement Scale (GAIS) at each visit. The GAIS will be completed by both the subjects and the evaluating investigators; The volume of material required to achieve an optimal correction result will be assessed at baseline and at optional touch up; The pain intensity after injection of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine) will be assessed using a Numerical Rating Scale (NRS) 2 hours after the injection; The patient satisfaction and the usability of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine) will be evaluated with a specific questionnaire, completed by the Principal Investigator.
The Safety of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine) will be assessed by facial examination and vital signs over the duration of the study. Adverse events and serious adverse events will be collected at each planned visit into a diary dispensed to patients.

盲法说明
The study will be double-blinded: patients and the treating investigator will not know which variant of each product (with and without lidocaine) will be injected in the left/right side of the face (or in the upper/lower lip for CLHA Hydrogel 20 mg/ml) and the evaluating investigator will be different from the treating investigator.

结局指标
主要结局
Evaluation of the CLHA performance in the perioral lines
时间窗: 6 months
The performance of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine), for the correction of congenital and acquired deficits of soft tissue in the perioral lines, will be evaluated using the change from baseline to V3 in the Wrinkle Severity Rating Scale (WSRS) for 18mg/ml CLHA formulations. WSRS is a validated 5-point scale (1 = Absent, 5 = Extreme)
Evaluation of the CLHA performance in the lips
时间窗: 6 months
The performance of Crosslinked Hyaluronic Acid Hydrogel (with and without Lidocaine), for the correction of congenital and acquired deficits of soft tissue in the lips, will be evaluated using the change from baseline to V3 in the Lip Fullness Scale (LFS) for 20 mg/ml CLHA formulation. LFS is a validated 5-point scale (0 = Very Thin, 4 = Full).
