Definitions
- Non-rinsed chemical foam containing trifarotene and its use in the treatment of acne
- the present invention relates to a topical product not rinsed in the form of a foam for the pharmaceutical or cosmetic treatment of the skin comprising trifarotene.
- Trifarotene is a new retinoid and corresponds to 3 "-tert-butyl-4 '- (2-hydroxyethoxy) -4" -pyrrolidin-1-yl [1,1', 3 ', 1 "] terphenyl-
- the present invention also relates to the use of the product according to the invention for the treatment of acne.
- compositions for a more practical and fast topical application.
- Foams help to overcome tolerance problems through better dose control, thanks to their spreading properties and low density.
- compositions intended for a known topical application may cause side effects which may limit their use and therefore their effectiveness.
- actives have the major disadvantage of inducing irritation that may result in poor tolerance of the product. This can thus create on the part of the patient a behavior of non-observance of the treatment and the discontent with regard to said treatment. There is therefore a need to develop new dosage forms overcoming the aforementioned drawbacks in terms of tolerance, effectiveness and compliance.
- trifarotene as many retinoids is known to be difficult to tolerate by consumers following acne treatment. This tolerance is very variable depending on the formula used as a vehicle. The patient also often feels that by applying larger amounts of product, he will go towards a faster healing. This behavior leads to excessive irritation, non-compliance and discontinuation of treatment.
- the composition according to the invention has the advantage of being in the form of a foam generated extemporaneously, and very well tolerated. After its application, the composition according to the invention is not removed by rinsing.
- composition is particularly well tolerated, even though it is not rinsed off, as shown in the examples illustrating one of the methods of assessing tolerance presented hereinafter.
- composition also has the advantage of remaining on the surface of the skin (stratum corneum and epidermis essentially), in order to avoid undesirable effects such as irritation and to obtain a foam adapted to the treatment of the skin. acne.
- the effectiveness of an active ingredient is related to the release and kinetics of penetration of the active through the skin.
- the form composition plays its essential role of vehicle of the active ingredient so that it reaches its therapeutic target.
- the release-permeation test described in Example 5 on ex-vivo human skin highlights the advantage of applying a chemical foam containing trifarotene.
- formulations of the invention make it possible to obtain a foam composition making it possible to reduce the undesirable effects and in particular the irritation.
- Aerosols in which the foam is generated by a propellant gas but with the disadvantage of being aerosols with the risks well known to them (pollution, respiratory risks in particular).
- Foaming formulas that are not very rich in foaming surfactants but packaged in a package provided with a mechanical foam generating system (pump with pulvorex type grid). This type of formulation requires the use of foaming surfactants that can induce irritation in rinsed products.
- compositions for topical application containing trifarotene in well-tolerated compositions for application topically in humans particularly a non-rinsed application (i.e., the composition is not rinsed off after application).
- the object of the present invention is therefore to provide a composition that meets these needs.
- Foaming surfactants are defined as surfactants which produce a voluminous, stable and unctuous foam when they are mixed with water according to tests well known to those skilled in the art.
- Foaming surfactants include anionic surfactants, cationic surfactants, amphoteric surfactants and nonionic surfactants of the alkylpolyglucoside and glucamide family.
- the pharmaceutical form according to the invention has the advantage of guaranteeing good stability of trifarotene.
- this formulation advantageously leads to the production of a soft, perfectly tolerated and non-irritating foam, which allows a better coverage of the area to be treated and makes it possible to overcome the problems of tolerance by a better control of the dose, thanks to the spreading properties and the low density of the foam.
- this dosage form does not require for its implementation the use of propellants or aerosols.
- aerosol or spray foams are excluded from the scope of the invention.
- foams of the prior art of the type open creams and / or foaming formulas requiring a mechanical foam generating system are also excluded from the invention.
- the present invention finally relates to the cosmetic use of the composition according to the invention, by topical application of this composition to the skin, and a medicament for topical application to the skin, comprising such a composition.
- the subject of the present invention is also the composition according to the invention for its use in the treatment of acne.
- FIG. 1 illustrates the production of a composition in the form of a foam according to the invention.
- the photo on the left represents the moment of mixing (T0) and the photo on the right represents the foam obtained when the acid / base chemical reaction is complete.
- FIG. 2 illustrates Example 5 and represents the comparative penetration-permeation results in the stratum corneum, the epidermis and the dermis of a foam composition according to the invention at 0.01% by weight of trifarotene composed of the mixture of intermediate compositions.
- A2 and B3 described in Example 1 in a ratio of 50/50 by weight

- the tested formulas are:
- An intermediate composition of acid formulation A7 example placebo (that is to say, not containing trifarotene),
- Measurements of MTT according to the current OECD protocol indicate that all formulas tested are non-irritating.
- the IL-1a assay of the complete formula according to the invention after a short time and a long time of exposure shows a lower level of irritation markers after application of the commercial reference.

- Table IV The values are expressed as a weight / weight percentage relative to the weight of each of the two intermediate formulas
- the amount of citric acid is greater than or equal to 1, 4, the amount of foam is optimal when the disodium pyrophosphate is present in the composition according to the following equation:
- Protocol of the study is to evaluate the penetration and distribution of different formulations according to the invention in human skin. Protocol of the study:
- trifarotene is measured in: the unabsorbed fraction, the stratum corneum, the epidermis, the dermis and the receiving liquid.
- This study makes it possible to study the influence of the formulation on the release of the active ingredient and its permeation through the skin.
- the aim is to compare the distribution of trifarotene in the different layers of the skin in the case of the application of a well-known formula and the application of a composition in the form of chemical foam.
- the tested formulas are:
- the scattering cells used are static diffusion cells, based on Franz model diffusion cell, with the following characteristics:
- the receiving compartment is surrounded by a water jacket heated to 37 ° C ⁇ 1 ° C, ensuring a temperature of 32 ° C ⁇ 1 ° C on the surface of the skin.
- the receptor compartment is separated from the donor compartment by the skin membrane, the epidermal face being on the donor side.
- the Receiver compartment containing a magnetic stirring bar was filled with the receiving fluid so as to prevent any formation of air bubbles. During the diffusion time, the receiving fluid was stirred continuously to ensure homogenization
- Skin samples from donors aged 42, 44 and 69 years were mounted on the diffusion cell with PBS as the receiving fluid.
- the average skin thickness was 0.89 ⁇ 0.07 mm with a maximum of 1.39 mm and a minimum of 0.45 mm. Thicknesses of all specimens.
- TEWL trans-epidermal water-insensitive loss
- the present study confirms the obtaining of a foam which remains on the surface of the skin, in order to avoid undesirable effects such as irritation and to obtain a foam adapted to the treatment of acne.
