Study Overview

• Status: Completed
• Conditions: Skin Aging; Skin Wrinkling
• Intervention / Treatment: Device: mesofiller® mesotox

Detailed Description

The product mesofiller® mesotox is a dermal filler manufactured by mesoestetic Pharma Group s.l. It was intended to be used as a temporary dermal filler for dermatological treatment for aesthetic purposes. The product provides a temporary filling of dermal tissue to correct small skin defects, such as wrinkles or scars in the upper part of the face, while also providing hydration to the face.

mesofiller® mesotox is a sterile, injectable, gel colourless, transparent, non-pyrogenic, reabsorbable product made out of cross-linked hyaluronic acid of non-animal origin, produced via bacterial fermentation.

This clinical investigation was conducted as an uncontrolled - no comparator medical device or other product was used. The safety and performance of the treatment were evaluated by comparison of the condition with the state of the treated area before initiation of the procedure, conducted by the trained Principal Investigator.

The investigated product mesofiller® mesotox was applied by intradermal or subcutaneous injection by the investigator during Session 1 for all subjects and Session 2 for the subjects, for whom a touch-up was considered beneficial. Both sessions were conducted within 14-day intervals.

The evaluation process during the medical examination was facilitated by photographic evidence taken before and after therapy at predetermined time points for reference.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Frequency and severity of AEs, SAEs, ISRs, TEAEs	Two months after the first treatment (Session 3 (Day 60)).

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Lemperle's Scale - principal investigator evaluation	The absolute change in Lemperle's Scale from baseline as evaluated by the investigator based on the photographs of the treated area. The Lemperle's scale is a six-point photographically based classification (0 means no wrinkles, 5 means very deep wrinkles, redundant folds) of mimetic wrinkles and folds that are graded using reference photographs.	Session 1 (Day 1); Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
Glogau class - principal investigator evaluation	The absolute change in Glogau class from baseline as evaluated by the investigator based on the photographs of the treated area. Glogau photoaging classification includes grades from Grade/Type I (mild) meaning no wrinkles to Grade/Type IV (severe) meaning only wrinkles.	Session 1 (Day 1); Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180) .
Wrinkle Severity Rating Scale (WSRS) - principal investigator evaluation	The absolute change in the Wrinkle Severity Rating Scale from baseline, evaluated by the PI based on photographs of the treated area. The scale ranges from grade 1 to 5, with grade 1 representing the best possible outcome.	Session 1 (Day 1); Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
Wrinkle Severity Rating Scale (WSRS) - patient evaluation	The absolute change in the Wrinkle Severity Rating Scale from baseline, evaluated by the patient. The scale ranges from grade 1 to 5, with grade 1 representing the best possible outcome.	Session 1 (Day 1); Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
Global Aesthetic Improvement Scale (GAIS) - principal investigator evaluation	Improvement in the Global Aesthetic Improvement Scale as evaluated by the PI based on the photographs of the treated area. GAIS ranges from grade 1 to 5, where grade 1 shows exceptional improvement.	Session 1; Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
Global Aesthetic Improvement Scale (GAIS) - patient evaluation	Improvement in the Global Aesthetic Improvement Scale as evaluated by the patient. GAIS ranges from grade 1 to 5, where grade 1 shows exceptional improvement.	Session 1; Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
Subject satisfaction	The Patient's Questionnaire was utilised. The satisfaction survey grades range from 1 to 3, where grade 1 represents the highest satisfaction level.	Session 1; Session 2 (Day 14); Session 3 (Day 60); and Session 4 (Day 180).
