Brief Summary

A Post-Market, Single-arm, Confirmatory Interventional Clinical Investigation to evaluate the Performance and Safety of INNEA and INNEA AQUA for the treatment of cheek and décolletage wrinkles

Detailed Description

Investigational product:

INNEA and INNEA AQUA are CE-marked medical devices indicated for intradermal injections. In particular:

• INNEA is a sterile, biodegradable, isotonic, dermal filler. INNEA consists of high chain (1,0-1,5 x 106 Dalton) hyaluronic acid (HA), obtained from Streptococcus equip bacteria, formulated to a concentration of 20 mg/ml in a physiologic buffer. Each box contains one syringe of INNEA, two 30G 1⁄2" disposable sterile needles reserved for injection of INNEA and a product leaflet.
• INNEA AQUA is a sterile, biodegradable, isotonic, intradermal filler. INNEA AQUA consists of a calibrated mix of medium weight (1200 - 1500 KDalton) HA and a low weight (200 - 400 KDalton), obtained from Streptococcus equi bacteria, formulated to a concentration of 25 mg/ml in a physiologic buffer and trehalose. Each box contains one syringe of INNEA AQUA, two 30G 1⁄2" disposable sterile needles reserved for injection of INNEA AQUA and a product leaflet.

Indications:

in the physiological process of aging of the skin, the effects of which include inspissation of the horny layer (roughness and reduced radiance of the skin) and changes in the elastic fibers of the dermis (wrinkles),

• in the dermal tissue repair process, in cases of scar results following superficial cutaneous trauma (e.g., acne and chickenpox scars).

Study procedure:

This is a post-market confirmatory interventional clinical investigation aimed to enroll adult women requiring correction of cheek and/or décolleté wrinkles. The investigation will be useful to collect INNEA and INNEA AQUA performance/safety evidence.

Each Subject, after signing the Informed Consent Form (ICF), will enter into a screening phase during which the baseline tests will be conducted. If the Investigator is able to organize and perform all tests in the same day, the screening phase and the baseline visit (V0) may coincide, and the patient can be treated immediately after signing the ICF. For each Subject, 5 visits will be planned during which several assessments will be performed as described in the Flowchart.

At V0, the Investigator will collect demographic data (e.g., sex, age, weight), medical history (e.g., history of autoimmune disease, diabetes, etc.), current clinical condition, drug allergy history, and Fitzpatrick phototype (as per clinical practice) of the enrolled Subject.

At V0, according to the instructions for use (IFU), the enrolled patients will be treated with one of the two IPs:

• INNEA, three injections at one week interval.
• INNEA AQUA, three injections at one week interval.

Subjects can be treated in one or two of the following areas with one of the two IPs (which will be the same for the three injections planned):

• Cheek
• Décolletage Performance will be evaluated by the Investigator using the Lemperle Rating Scale (LRS) for cheek wrinkles at each visit, and the Global Aesthetic Improvement Scale (GAIS) for décolletage wrinkles at each post-treatment assessment. In addition, global aesthetic appearance of the face will be assessed through GAIS by the Investigator. Skin radiance and turgor will be evaluated by Subjects using a 5-Likert scale.

After each injection, the Investigator will record Subjects' pain intensity using the Numerical Rating Scale (NRS).

Safety will include assessment of vital signs and evaluation of possible cutaneous reactions at each visit. Adverse events, concomitant medications, and device deficiencies will be monitored during the entire duration of the study.

A 5-point Likert Scale will be used by Subjects to assess patient satisfaction with treatment at EOS visit (V4).
