Background and study aims
Acne is a common skin condition which causes spots to develop on the skin, usually the face, chest and back. Even cases of mild acne can be distressing, as not only can it make people feel self-conscious, it can be painful. The majority of treatments for acne involve applying medications directly to the skin (topical medication), such as creams, gels and lotions. These products can contain a wide range of different chemicals, including retinoids (vitamin A by-products that help to remove dead skin cells from the surface of skin), antibiotics (which kill bacteria on the skin that can cause infections leading to spots) and keratolytic substances (peeling agents). When acne affects the chest or back, it can be difficult to apply topical medications in the form of creams, gels and lotions as these areas can be hard to reach. Sprays are therefore considered to be a far more convenient treatment option, as they are able to reach where the sufferer otherwise would not be able to. The aim of this study is to compare three different acne spray formulations, in order to find out if a spray containing retanoids, antibiotics and keratolytic substances is more effective than sprays containing keratolytic substances alone.
Who can participate?
Adults with mild to moderate acne on the back and chest.
What does the study involve?
Participants are randomly allocated to receive one of three products. The first product is a new spray which contains retinol and hydroxypinacolone retinoate (vitamin A by-products), an antibacterial product, salicylic acid (a plant hormone commonly used to treat common skin and foot warts) and, vitamin E. The second and third products both contain different keratolytic substances (peeling agents that help to soften and shed the outer layer of skin). All products are applied twice a day for six weeks using four to five sprays on the affected area of skin. At the start of the study and after six weeks, participants in all groups have their acne examined to find out if there has been any improvement. Participant are also interviewed after six weeks in order to find out how their skin has reacted to the spray that they used.
What are the possible benefits and risks of participating?
Participants may benefit from an improvement to their acne as a result of using the treatment sprays. There are no notable risks involved with taking part in the study, although there is a chance than the product used may not be effective or cause skin irritation.

Scientific title | Efficacy and local tolerability of different spray products in the treatment of mild to moderate acne of the back and chest: A controlled, three-arm, assessor-blinded prospective trial |
Study objectives | The aim of this study is to evaluate whether a spray containing retinoids, antibacterial, emollient and keratolytic substances is more effective than other two products containing containing keratolytic and emollient compounds only at treating moderate acne of the chest and back. |
Ethics approval(s) | Policlinico Federico II Naples, 10/01/2015 |
Health condition(s) or problem(s) studied | Truncal acne vulgaris |
Intervention | Participants are randomly allocated in a 1:1:1 ratio to receive one of three products. Product 1: A new spray formulation containing 0.15% of two vitamin A derivatives (retinol and hydroxypinacolone retinoate) carried in a patented glycospheres system (RetinSphere®), an antimicrobial peptide (BIOPEP.15), salicylic acid and, vitamin E (BR). Product 2: A spray formulation containing triethyl citrate and ethyl linoleate, GT-peptide-10, salycilic acid 0,5% and Zinc Lattate. Product 3: A spray formulation containing betaine, glycine and salicylic acid 2% (SP). All products are to be applied twice daily (one application in the morning and one application in the evening) for 6 consecutive weeks. The total amount of product is 4/5 puffs per application (a total of 1.2/1.5 ml), in order to cover chest and back areas. All participants are followed up at six weeks. |

Pharmaceutical study type(s) | |
Phase | Phase III/IV |
Drug / device / biological / vaccine name(s) | 1. Bioretix ultra spray 2. Aknicare CB 3. Salipil spray |
Primary outcome measure | Clinical evolution of acne lesions is measured using the Global Acne Grading System (GAGS) at baseline and 6 weeks. |
Secondary outcome measures | Skin tolerability is measured by evaluating skin irritation (erythema and burning) and skin xerosis using a quantitative score from 0(no symptom) to 3(relevant symptom) at 6 weeks. |
