Evaluation of Efficacy and Safety of HCC_45 for the Correction of Acne Scars of the Face

Interventional, Post-marketing, Local, Mono-centric Study for Evaluation of Efficacy and Safety of HCC_45 for the Correction of Acne Scars of the Face

Acne scars represent a frequent complication of moderate/severe acne and may negatively impact on psychosocial and physical well-being of acne patients. Several types of acne scars have been classified and the same patient is likely to have more than one type. Each type can be treated with varying degrees of success. The main acne scars are the following:

Atrophic or Depressed Scarring:

• Ice pick: An ice pick scar has a wide shaft that narrows down to the tip. It resembles a hole that's wide at the top and narrows to a point as it goes deeper into the skin. Such an indentation is common and one of the most challenging scars to heal. This scar is more frequent on forehead and upper cheeks, where skin is thinner.
• Rolling: These scars are typically found on the lower cheeks and jaw, where skin is thicker. The indents have sloping edges that makes the skin look uneven and wavy.
• Boxcar: Boxcar scars are indents that have sharper edges. Those edges go down deep into the skin. These scars are common on the lower checks and jaw.

Study Overview

• Status: Completed
• Conditions: Acne Scars - Mixed Atrophic and Hypertrophic; Ice Pick Scars; Rolling Scars; Boxcar Scars
• Intervention / Treatment: Device: HCC_45

Detailed Description

Open label clinical trial, conducted by 1 center under dermatological control.

Primary aim of the study is to evaluate the efficacy and the safety of the deep injection of HCC_45 in acne scars of the face (ice picks, rolling, boxcars).

Secondary endpoint is self-assessment questionnaire regarding treatment efficacy and tolerance.

HCC_45 is a resorbable medical device 2 ml nonpyrogenic pre-filled syringe, containing 2 ml of hyaluronic acid for intradermal use. The principal component of the medical device is Hyaluronic Acid of non-animal origin, produced by bacterial fermentation.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: HCC_45 treatment group; Treatment of acne scars of the face by using a subcision+injection technique: the needle (25 G) or cannula (25 G) (wider areas are treated with the cannula) is inserted into the skin and made to move with a back-and-forth motion in order to detach scar collagen bundles. Then 1 syringe (2 ml) of HCC_45 is injected. Day 0: Information and consent form provided, Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. First treatment of HCC_45 (refer to study protocol). Day 30 (1 month after day 0): Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. Second treatment of HCC_45 (refer to study protocol). Day 120 (4 months after day 0): Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. NO treatment, Self-evaluation questionnaire.

Device: HCC_45; Dosage form: HCC_45 is a resorbable medical device 2 ml non-pyrogenic pre-filled syringe, containing 2 ml of hyaluronic acid for intradermal use. The principal component of the medical device is Hyaluronic Acid of non-animal origin, produced by bacterial fermentation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline of Skin Roughness and flaccidity at 30 days and at 120 days post-injection	Visual score from 1 (milder scarring) to 4 (severe scarring) (Goodman and Baron Grading Scale of Postacne Scarring)	Day 0, Day 30, Day 120
Change from Baseline of Skin's surface Profilometry at 30 days and at 120 days post-injection	A measurement of the skin surface affected by acne scars is taken thanks to Primos compact portable device (GFMesstechnik); Primos software is able to measure skin principal profilometric parameters in vivo or on skin replicas, the software compares directly the different images obtained at the times foresee by the protocol.	Day 0, Day 30, Day 120

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Efficacy questionnaire	Self assessment questionnaire regarding the efficacy of the study treatment on acne scars (score: very marked; marked; medium; light; absent;)	Day 120
Treatment tolerance questionnaire	Self-assessment score: bad; poor; good; excellent	Day 120
