Brief Summary

STYLAGE® L Lidocaine is a CE-marked hyaluronic acid gel intended to fill skin depressions on the face by dermal injection. In this study, 50 healthy subjects between the age of 30 and 65, with moderate to severe nasolabial folds as assessed in live, who have given their informed consent and met all eligibility criteria, will be enrolled. Subjects will randomly receive injection of STYLAGE® L Lidocaine on one nasolabial fold and injection of an active comparator on the other nasolabial fold. A touch-up is possible if required one month after. Subjects will come to a total of 7 visits over a period of 12 months. Variation in severity score of nasolabial folds will be assessed in live and on photographs by independent evaluators. Variation in nasolabial fold depth, global aesthetic improvement, subject satisfaction, pain at injection site and safety will also be assessed.

Detailed Description

This is a prospective, multicenter, randomized, controlled versus active treatment, within-subjects study with blinded subjects and evaluators assessing the efficay and safety of STYLAGE® L Lidocaine in the treatment of nasolabial folds. Fifty healthy subjects between the age of 30 and 65, with moderate to severe nasolabial folds attaining either grade 3 on both sides or grade 4 on both sides on the Wrinkle Severity Rating Scale (WSRS) for nasolabial folds as assessed in live, who have given their informed consent and met all eligibility criteria, will be enrolled. Subjects will randomly receive dermal injections consisting in a maximum of 2 mL of STYLAGE® L Lidocaine on one nasolabial fold and a maximum of 2 mL of an active comparator on the other nasolabial fold. A touch-up consisting in the dermal injection of maximum 1 mL of product per nasolabial fold is possible if required one month after. Subjects will be followed up at 1, 3, 6, 9 and 12 months timepoints. Variation in severity score of nasolabial folds will be assessed in live and on photographs by independent blinded evaluators using the validated 5-point Wrinkles Severity Rating Scale (WSRS). Global aesthetic improvement will be assessed using the Global Aesthetic Improvement Scale (GAIS). Variation in nasolabial fold depth will be assessed using Dermatop®. Subject satisfaction, pain at injection site and safety will also be assessed.

Study Groups

Nasolabial fold treated with experimental device

STYLAGE® L Lidocaine is a hyalorunic acid injectable gel whose intended purpose is the filling of skin depressions on the face by dermal injection.

Up to 2 mL will be injected at Day 0 on a nasolabial fold and, if required, up to 1 mL could be injected 1 month after on the same nasolabial fold (touch-up).

Group Type: EXPERIMENTAL

STYLAGE® L Lidocaine

Intervention Type: DEVICE

An injection of maximum 2 mL on one nasolabial fold is planned at Day 0. A touch-up of maximum 1 mL on the same nasolabial fold is possible 1 month after D0 (month 1).

Nasolabial fold treated with comparator

The active comparator is a hyalorunic acid injectable gel whose intended purpose is the filling of mid and/or deep depressions of the skin via mid and/or deep dermal injection.

Up to 2 mL will be injected at Day 0 on a nasolabial fold and, if required, up to 1 mL could be injected 1 month after on the same nasolabial fold (touch-up).

Group Type: ACTIVE_COMPARATOR

Active control

Intervention Type: DEVICE

An injection of maximum 2 mL on one nasolabial fold is planned at Day 0. A touch-up of maximum 1 mL on the same nasolabial fold is possible 1 month after D0 (month 1).
