Assess the Effects and the Tolerance of Cosmetic Product in the Follow-up Phase of Facial Acne for 1 Year

An International Multicentric Open-label Descriptive Study to Assess the Effects and Evaluate the Tolerance of the Cosmetic Care Product RV3278A in the Follow-up Phase of Facial Acne in Teenagers and Young Adults for 1 Year

Acne is a chronic inflammatory disease of the pilo-sebaceous unit in the skin. Indeed, your skin is covered with tiny holes called hair follicles, or pores. These pores contain sebaceous glands (also called oil glands) that make sebum, an oil that moistens your hair and skin. Most of the time, the glands make the right amount of sebum and the pores are fine. But sometimes a pore gets clogged up with too much sebum, dead skin cells, and germs called bacteria. This can cause acne.

Pierre Fabre Laboratories have developed a cosmetic care product, a cream which is commercialized since September 2019. This leave-on skin care product is adapted for acne-prone skin.

In this study, we are interested in the effects of this care product in facial acne evolution for 12 months (quality of life, acne severity, number of acne flares). Also, we are interested in the subject's satisfaction regarding the use of this care product. This study will also enable to know if the product is well tolerated in such application circumstances.

This clinical study will be carried out in 54 subjects (female or male), aged between 12 and 35 years, in about 10 centers in different European countries.

The maximal duration of the study for a subject will be 1 year. If you give your consent to take part in this study, you will receive a cosmetic care product, also called study product, that you will apply on your face twice a day (morning and evening) for the whole duration of the study.

What makes this study original is the use of a smartphone application to help you to comply with the study procedures and to help the investigator to follow you.

Study Overview

• Status: Completed
• Conditions: Acne Vulgaris
• Intervention / Treatment: Other: RV3278A

Detailed Description

Acne vulgaris is one of the most common skin conditions in teenagers that often persists into adulthood. It is a chronic inflammatory disease of the pilosebaceous unit resulting from four main factors: increase of sebum production, follicular hyperproliferation and hyperkeratinisation leading to comedones formation, inflammation and proliferation of the bacteria Propionibacterium acnes.1,2 Acne affects nearly all people between the ages of 15 and 17 years and in 15 to 20% of young people, acne is moderate to severe. The prevalence of acne in 12-24 years is 85%. 3 The presence of acne may have psychologic or emotional impact: it may negatively affect mood, quality of life and self-esteem in adolescents and adults and can increase the risk of anxiety, depression and suicidal ideation2,3. There is not always a correlation between the acne clinical severity and the quality of life.

According to its severity, the acne vulgaris can be treated locally with topical agents used alone or in combination, such as benzoyl peroxide, retinoids (adapalene…), antibiotics, azelaic acid, etc.

Oral treatments are usually taken for more severe acne and include antibiotics, contraceptives and isotretinoin. They also can be used in combination with local treatments.1,4

The product RV3278A is a non-rinsed cosmetic cream intended to be used every day on adolescents and young adults with acne-prone skin.

In accordance with the Pierre Fabre laboratories safety charter, a full program of tolerance has been performed including pre-clinical and clinical studies in healthy volunteers. The product presents a sufficient safety level to be used for this protocol.

The use of cosmetics in acne is well established. The goals of cosmetics in acne are

• to complement drug therapy, by alleviating their side effects and thereby improving treatment adherence.
• to contribute to improving the status of the clinically non-lesional skin.

Clinically non-lesional skin in acne patients (CNLSAP) is well known for its greasiness, which is due to overproduction of sebum.

Another important character of the CNLSAP is the "invisible microcomedone" (IMC).

1. IMC can be visualized by "stripping-it-out" with cyanoacrylate.
2. IMC is composed as a mixture of cellular components of the follicular infundibulum, and sebum lipids, both of which can be analysed ex-vivo by all tools of currently available technology.
3. IMC is considered to be the root of any subsequent clinical lesion, both non- inflammatory ones (open and close comedones microcysts) and inflammatory ones (papules pustules etc..)5
4. The number/cm2 and size of the IMC are highly variable and correlate with subsequent acne severity.
5. Therefore, any cosmetic product able to modify the number/cm2 and size of the IMC would contribute to maintain healthier skin in acne patients and reduce the use of drug therapy.

A pilot study in acne patients has shown that an herbal extract used topically for several weeks months was able to reach such goals.

The present study is aimed at reproducing these results in several dermatology practices in Europe.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in acne severity from Baseline to 365 days	Global Evaluation Acne (GEA), a 6-point scale 0 : Clear, No lesions; : Almost clear, Almost no lesions; : Mild; : Moderate; Severe; : Very severe	Day 1, Day 35, Day 120, Day 180, Day 270, Day 365
Number of acne relapse(s)/flare(s)	Acne flare or relapse are defined by the necessity to introduce an oral and/or facial anti-acne treatment and GEA score ≥3.	1 year-period
Change in Acne lesions counting	Each type of acne lesions (non-inflammatory and inflammatory: open comedones, closed comedones, papules, pustules and nodules) will be counted on the whole face at each visit by the investigator according to the Lucky method	Day 1, Day 35, Day 120, Day 180, Day 270, Day 365
Change in Cardiff Acne Disability Index questionnaire (CADI)	It consists in 5 questions regarding the way the subject feels about the acne, each response is on a 4-point scale. The score is calculated by summing the score of each question resulting in a possible maximum of 15 and a minimum of 0. The higher the score, the more the quality of life is impaired.	Day 1, Day 180, Day 365
Change in Subject's Global Assessment (SGA) of acne severity	The subject will assess the global severity of his/her acne on a 7-point scale in comparison to acne severity at baseline (visit 1): (-3) Very much worse (-2) Much worse (-1) Minimally worse (0) No change; Minimally improved; Much improved; Very much improved	Day 35, Day 120, Day 180, Day 270, Day 365
Change in pilosebaceous follicles status on forehead area	Ex vivo analysis of pilosebaceous follicles will be performed by cyanoacrylate skin surface stripping method	Day 1, Day 180 and Day 365 for the majority of the centres. 2 designated centres will performed it also at Day 35, Day 120 and Day 270
Occurrence of Adverse events	It will be determined by the subject's / parent(s) or guardian(s) spontaneous reporting, the investigator's non-leading questioning, his/her critical review of the e-diary and his/her clinical evaluation	1 year
Change in Local tolerance	by the Investigator using a 4-point scale for each physical or functional sign on the whole face: none, mild, moderate, severe	Day 1, Day 35, Day 120, Day 180, Day 270, Day 365
Change in Tolerance	The following 5-point scale will be used by the investigator: (1) Excellent: no functional nor physical signs related to the investigational product observed or reported by the subjects; (2) Very good; (3) Good; (4) Moderate; (5) Bad	Day 1, Day 35, Day 120, Day 180, Day 270, Day 365
Global Tolerance	Based on the same 5-point scale. The investigator will consider: The type of reaction (discomfort, irritation, delayed/immediate allergic reaction) and its intensity, duration, recurrence, time of emergence; The population (age, acne skin…); The type of product	Day 365
Change in the subject statisfaction regarding the use of RV3278A	Questionnaire	Day 1, Day 120, Day 365
