An Interventional Study to Evaluate the Safety and Performance of Crosslinked Hyaluronic Acid Hydrogel

An Interventional, Pre-Market, Double-Blinded, Controlled, Two Stages Study to Evaluate the Safety and Performance of Crosslinked Hyaluronic Acid Hydrogel (With and Without Lidocaine) for the Treatment of Soft Tissue Deficits

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.

Study Overview

• Status: Recruiting
• Conditions: Dermal Filler; Volume Deficiency of the Midface
• Intervention / Treatment: Device: Crosslinked Hyaluronic Acid (CLHA) Hydrogel with and without Lidocaine

Detailed Description

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Crosslinked Hyaluronic Acid (CLHA) Hydrogel with Lidocaine; Patients were treated, on one side of the face with crosslinked Hyaluronic Acid Hydrogel with 0.3% lidocaine hydrochloride.	Device: Crosslinked Hyaluronic Acid (CLHA) Hydrogel with and without Lidocaine; The injection should be performed at variable depth of the skin (dermal or subdermal), depending on the area to be treated and on the product variants, in accordance to the IFU of the IPs
Experimental: Crosslinked Hyaluronic Acid (CLHA) Hydrogel without Lidocaine; Patients were treated, on the other side of the face with crosslinked Hyaluronic Acid Hydrogel without lidocaine hydrochloride.	Device: Crosslinked Hyaluronic Acid (CLHA) Hydrogel with and without Lidocaine; The injection should be performed at variable depth of the skin (dermal or subdermal), depending on the area to be treated and on the product variants, in accordance to the IFU of the IPs
