COMPOSITIONS FOR THE TREATMENT OF EPISTAXIS

RELATED APPLICATIONS

This application hereby incorporates United States Non-Provisional Application No. 14/203,246, filed March 10, 2014, and United States Provisional Application No. 61/775,598, filed March 10, 2013, by reference in their entirety.

BACKGROUND OF THE INVENTION

Topical disorders are widespread and include a number of different conditions of the body surfaces such as the skin, nails and mucous membranes. Topical disorders include but are not limited to various kinds of dermatitis, acne, rosacea, onychomycosis, pityriasis, actinic keratosis, eczema, erythema, urticaria, hemorrhoids, anal fissures, anal pruritus, common warts, genital warts, anal warts, herpes and epistaxis. Currently, there are a number of topically applied formulations for the treatment of topical conditions, including ointments, creams, gels, lotions, jellies and pastes, foams, sprays and medicated pads.

Epistaxis or nosebleed, the term used to describe hemorrhage from the nose, is relatively common, usually noticed when the blood drains out through the nostrils. There are two types: anterior (the most common), and posterior (less common, more likely to require medical attention). Sometimes in more severe cases, the blood can come up the nasolacrimal duct and out from the eye. Fresh blood and clotted blood can also flow down into the stomach and cause nausea and vomiting.

While usually not life threatening, Epistaxis is a topical disorder for which there is no arsenal of effective and safe treatments.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides topical compositions and methods of treatment of

Epistaxis disorders.

The topical compositions of the present invention are applied to the Epistaxis affected nostril of a subject in need thereof. Topical formulations typically comprise polar solvents which enable the incorporation of the medicaments into the formulation. The major disadvantage of these topical formulations comprising polar solvents, e.g. ethanol, is their stinging effect when applied to the mucosal surface (mucous membrane). In contrast to currently available topical formulations, the topical compositions of the present invention comprise an aqueous phase which allows dissolution and substantially homogeneous distribution of the pharmaceutical agents. In an embodiment, addition of water to the topical composition reduces the use of stinging polar solvents and hence improves the compliancy of the subject to be treated. It is further disclosed that the topical compositions of the present invention, upon drying, form a film on the nasal mucosa surface and thus provide a protective coating

In addition, the topical compositions of the present invention, when dried, form a durable film which does not crack or flake off and remains intact for more than 12 hours giving release of the pharmaceutical agent for an extended period of time, thus leading to enhanced healing of the affected areas.

The sustained or extended release of the pharmaceutical agent(s) from the compositions of the present invention enables methods of treatment including less frequent administration (such as once daily, once every other day or twice weekly) than existing commercially available products, while achieving similar or better therapeutic results.

Further, the topical compositions of the present invention, when dried, form a flexible film, closely following irregularities of the body surface as well as movement of the body surface.

According to yet another aspect, the present invention provides a kit comprising a topical composition of the present invention, a container-applicator device suitable for storage and application of the composition to a body surface, and instructions for administering the topical composition to a subject in need thereof.

According to some embodiments, the container-applicator device is selected from the group consisting of a single use wipe, a nasal swab, a syringe, a dropper, a spray dispenser, a swab, a compressible bottle or tube, a spatula, a suppository insertion tube, an extrusion tube, a pump dispenser, a pressurized dispenser and an inflatable member.

According to another aspect, the present invention provides a topical composition for use in treating or preventing an Epistaxis disorder.

Other objects, features and advantages of the present invention will become clear from the following description and claims.

A topical composition of the present invention comprises at least one film forming agent, at least one surfactant, at least one non-polar volatile solvent, water and at least one pharmaceutically active agent. One such film forming agent may be a silicone resin. The topical composition can further comprise additives, such as dimethicone/vinyl dimethicone crosspolymers, silicone gum blends and gelling agents.

The term "film forming agent" or "film forming ingredient" or "film former", as used herein, means an inactive ingredient such as a silicone resin that after dissolution in at least one solvent and application on a substrate leaves a film on the substrate to which it is applied, for example once the at least one solvent evaporates, absorbs and/or dissipates on the substrate.

Silicone resins, such as polydimethylsiloxane and polymethylsilsesquioxane have an unique semi-organic structure and are flexible.

While using film forming agents in the instant invention, it is desirable to use such flexible film forming agents and formulate them in such compositions which produce flexible and durable films. In an embodiment, there are provided flexible and durable film forming compositions, providing beneficial therapeutic effects like reduced bleeding, pain and itching.

The film formed on the skin or mucosal surface allows the tissues to "breathe", which is beneficial because of the extended period of time the film stays on the tissues.

The compositions of the instant invention dry relatively fast after application on the mucosal surface between 5 seconds and 1 minute to form a durable and elastic film.

The film formed on the substrate is substantially dry, which means it contains less than 10% volatiles, typically less than 5% and less than 2% volatiles. The important aspect of the substantially dry films of this invention, whatever the percentage of volatiles left, is that they feel dry to touch. Without wishing to be bound by theory, the inclusion of the active pharmaceutical in the flexible film seems to have a long-acting or sustained release effect, achieving comparable or superior results compared to similar commercial products, while exposing the patient to smaller amounts of the active pharmaceutical ingredient(s).

In an embodiment, there are provided once daily Epistaxis topical compositions comprising:

(i) at least one flexible film forming ingredient

(ii) at least one surfactant;

(iii) at least one non-polar volatile solvent;

(iv) at least 15% w/w water; and

(v) a therapeutically effective concentration of at least one pharmaceutical agent,

wherein the composition is sufficiently designed to dry within 60 seconds after application to a mucosal surface of an Epistaxis affected nostril to form a dried composition, wherein the dried composition forms: (i) a flexible film, wherein the flexible film closely follows irregularities of the mucosal surface as well as movement of the mucosal surface, and (ii) a durable film, wherein the durable film does not crack or flake off and remains intact for more than 12 hours giving release of the pharmaceutical agent for an extended period of time. The dried film in non- soiling.

The above compositions may be topically administered even less often than once daily, such as once every other day or twice weekly.

In an embodiment, there are provided once daily Epistaxis topical compositions comprising: (i) at least one flexible film forming ingredient;

(ii) at least one surfactant;

(iii) at least one non-polar volatile solvent;

(iv) at least 15% w/w water;

(v) at least one viscosity modifier; and

(vi) a therapeutically effective concentration of at least one pharmaceutical agent,

wherein the composition is sufficiently designed to dry within 60 seconds after application to a mucosal surface of a nostril to form a dried composition, wherein the dried composition forms: (i) a flexible film, wherein the flexible film closely follows irregularities of the mucosal surface as well as movement of the mucosal surface, and (ii) a durable film, wherein the durable film does not crack or flake off and remains intact for more than 12 hours giving release of the pharmaceutical agent for an extended period of time. The dried film in non-soiling.

The selection of the inactive pharmaceutical ingredients and their concentration has an impact on the therapeutic effect of the compositions, so that extensive experimentation was needed until the optimal compositions were developed. Thus, for example, low concentrations of water result in incomplete solubilization of the active(s) and high water concentrations lead to slow rate of drying.

It has been surprisingly found that when a topical composition of the present invention is formulated for use as a nasal swab or a wipe, the addition of inactive ingredients like Pemulen®, have a profound effect on the viscosity of the compositions, lowering the viscosity even at concentrations below 0.1% w/w. Therefore, Pemulen® may be included in the composition for the nasal swabs or wipes, which requires a lower viscosity.

In an embodiment, the film forming agents used in the compositions of the present invention are non-polymerizable and therefore, unlike the polymerizable agents are less sensitive to moisture, more stable and more suitable for repeated use.

The term "volatile solvent", as used herein, means that the solvent has a measurable vapor pressure. The volatile solvents used in this invention are non-polar solvents. Some of the film forming agents according to the present invention are silicone resins. The non-limiting examples of silicone resins useful in the compositions of the invention are siloxysilicates, silsesquioxanes (usually denoted as T-resins) and a combination thereof. One non-limiting example of a siloxysilicate in accordance with the present invention is trimethylsiloxysilicate, which may be represented by the following formula:

[(CH3)3-Si-0]x-(Si04/2)y

wherein x and y may, for example, range from 50 to 80. Such siloxysilicates are commercially available from General Electric and Dow Corning under the trade name Resin MQ®. One non- limiting example of silsesquioxane is polymethylsilsesquioxane. Trimethylsiloxysilicate and polymethylsilsesquioxane are widely used in cosmetic industry due to their film forming properties. The present invention discloses for the first time the use of trimethylsiloxysilicate for therapeutic applications, inter alia, for treatment of Epistaxis disorders. Trimethylsiloxysilicate is soluble in the volatile solvent of a topical composition of the present invention. The amount of the silicone resin film forming agent in the composition is determined based on the desired adhesion properties of the dried film to the target surface. The amount depends, inter alia, on the target surface, the condition to be treated, and the amount of composition ingredients. The amount of the silicone resin film forming agent further defines the viscosity of the topical composition. The amount of the silicone resin film forming agent in the composition typically ranges from about 10% to 40%> w/w. The term "about" as used herein denotes ± 10 % of the value indicated.

The volatile solvent useful for dissolving the silicone resin is chosen from volatile silicone or volatile aliphatic hydrocarbon. Water solubility of the volatile solvent is less than about 0.1%. According to some embodiments, the volatile silicone solvent is a linear or cyclic polydimethylsiloxane, having from 2 to 9 silicon atoms, these silicones being optionally substituted with alkyl or alkoxy groups of 1 to 10 carbon atoms. The non- limiting examples of a siloxane such as methylsiloxane or a polydimethylsiloxanes in accordance with the present invention are hexamethyldisiloxane, heptamethyloctyltrisiloxane octamethylcyclotetrasiloxane, octamethyltrisiloxane, decamethylcyclopentasiloxane, decamethyltetrasiloxane, dodecamethylpentasiloxane, dodecamethylcyclohexasiloxane, and mixtures thereof. The polydimethylsiloxane used in the compositions is hexamethyldisiloxane.

The volatile solvent can further comprise a volatile aliphatic hydrocarbon. The aliphatic hydrocarbon in accordance with the present invention may be any aliphatic hydrocarbon, including an alkane, a mixture of alkanes, an alkene, a mixture of alkenes, an alkyne, a mixture of alkynes, an ester or a mixture thereof. The aliphatic hydrocarbon is an alkane such as pentane, isooctane, isododecane, isohexadecane or a mixture thereof. According to a certain embodiment, the aliphatic hydrocarbon is isooctane. The volatile ester useful for dissolving the film former may be a branched ester, such as isohexyl or isodecyl neopentanoate and mixture thereof.

The volatile solvent may comprise a volatile silicone, a volatile aliphatic hydrocarbon or a mixture thereof. According to a certain embodiment, the volatile solvent comprises methylsiloxane or a hexamethyldisiloxane and isooctane.

According to some embodiments, the presence of water in a topical composition of the present invention allows dissolution of the pharmaceutically active agents, which are not soluble in the non-polar volatile solvents used for dissolving the film-former, thus avoiding the need to use polar solvents. As the pharmaceutically active agents are completely dissolved in the compositions of the present invention and do not precipitate or crystallize on drying, the resulting essentially dry films comprising the active(s) are clear, transparent and not "white films".

The emulsion can be a water-in-oil or oil-in-water emulsion. According to exemplary embodiments, a topical composition of the present invention is an oil-in-water emulsion, wherein the aqueous phase includes the pharmaceutical agents dissolved therein and the oil phase includes the film forming agent dissolved in the volatile solvent. The oil-in-water emulsion allows the film former and the pharmaceutical active agents to be homogeneously dispersed in the topical composition. The stable emulsion provides fine dispersion of the emulsion ingredients in the topical composition, in the container- applicator device and upon the application to the target surface, such that once the volatile solvent and water evaporate both the film former and the pharmaceutical active ingredients remain finely dispersed on the target surface. The stable emulsion prevents clamping, floating and/or precipitation of the polar active ingredients in the non-polar volatile solvents. The presence of the aqueous phase in the topical composition further obviates the use of polar solvents, formerly required to dissolve and disperse pharmaceutical active ingredients in silicone based liquid bandages.

The amount of the volatile solvent and water affects the viscosity and evaporation time of the topical composition when applied to a target surface. The amount of the volatile solvent and water is determined so as to adjust the viscosity and evaporation time to desired values. The amount of volatile solvent and water further affects the morphology of the silicone/water emulsion. The amount of the volatile solvent can be adjusted to obtain the desired emulsion type. The amount of the volatile solvent in the composition typically ranges from about 30% to about 80% w/w. The amount of water can be adjusted to obtain the desired emulsion type. The amount of water in the composition typically ranges from about 20%> to about 40%> w/w.

The topical compositions of the present invention further comprise at least one surfactant. Addition of the surfactant allows mixing of the silicone and the aqueous phases, producing a silicone/water emulsion. Addition of the surfactant further allows the emulsion stabilization. As described hereinabove, the obtained emulsion may be an oil- in-water emulsion, wherein the aqueous phase includes dissolved pharmaceutical ingredients and finely dispersed volatile solvent phase, containing the dissolved film former.

(ii) from 3% w/w to 10% w/w micronised tranexamic acid;

(iii) from 15% w/w to 30% w/w trimethylsiloxysilicate powder; and

(iv) from 50% w/w to 75% w/w 1,1,1,2-tetrafiuoroethane.

Mode of administration, containers and applicators

The compositions for use in the present invention are generally stored in a container-applicator device for use in a single dose application (e.g., a wipe or a nasal swab in a disposable packing) or for use in repeated applications to the anus and rectum. Single dose applicators include those having breakable or removable seals that prevent moisture, including atmospheric moisture, from contacting the formulation.

The compositions may be administered to an Epistaxis affected subject in need thereof in the form of gel, nasal swab/wipe or nasal spray/aerosol.

In an embodiment of this disclosure, a topical water-based composition is in the form of a pre-packaged nasal swab/towelette/wipe. The nasal swab or wipe substrate is typically uniformly impregnated with the topical water-based composition. According to an embodiment, the topical water-based composition is in a liquid form, when applied to the wipe. According to an embodiment, the topical water-based composition is in a gel form, when applied to a nasal swab or wipe. The wipe provides the user with a single dose of sterile medication. The topical composition is transferred to the body surface upon contacting the wipe with the target surface.

The design of nasal swabs or wipes is well known to those of skill in the art. Each nasal swab or wipe is generally packaged as a single-use sealed unit. The nasal swab/wipe is formed of woven or non-woven fabric, cloth or tissue substrate and the impregnated nasal swab/wipe issealed into an enveloping sachet or pocket. The sachet or pocket is formed by sandwiching a folded and impregnated nasal swab or wipe between two sheets of an aluminum foil/polyethylene film laminate. The sheets of laminate may comprise folded over portions of a single sheet of such material.

A container-applicator may further comprise two parts: (1) a storage area or reservoir which holds the composition and protects it from air, water and contaminants; and (2) the applicator which generally comprises a specially shaped tip designed to aid in application of the composition to the nasal mucosa. In particular embodiments, the applicator is an element integral to the container, for example, an elongated insertion tube extending from a reservoir. Alternately, the storage area and the applicator may be separate components, such as a tube reservoir and a separately supplied dropper. In yet other embodiments, the container and the applicator may be supplied as separate elements which are connected during use, for example via compatible male and female connectors respectively provided on the container and the applicator or vice versa.

For repeated and intermittent usage, minimal exposure to atmospheric moisture is required. This can be achieved by devices having very narrow applicator outlets and low initial dead space. One applicator for such repeated intermittent use dispenses the composition in a controlled drop wise manner, as described for example in U.S. Pat. No. 4,958,748.

Still another container-applicator device comprises a brush or solid paddle applicator wherein the topical composition is "painted" onto the nostril requiring treatment.

The container-applicator device for repeated and intermittent usage may comprise a container suitable for non- sterile storage of the composition, and an applicator suitable for metered dispensing of the composition after opening of the applicator. In particular embodiments, the applicator is characterized as having a resealable opening of no more than about 0.05 square inch (0.323 square centimeters) so as to permit the metered dispensement of the composition from the applicator and which is capable of multiple administrations of the composition, and is further characterized as having resealing means such as a cap which either tightly mates with the applicator or which screws onto the applicator. The opening may be at the terminus of an elongated and tapered tube-like member suitable for insertion into the nostril. The opening of the applicator is about 0.001 to about 0.01 square inch (about 0.00645 to about 0.0645 square centimeters).

In an embodiment, the walls of the container-applicator device are made of a pliable material, so that upon application of pressure onto the walls, the walls depress sufficiently to force the composition in the container into the applicator and through the opening. In another embodiment, the composition is released from the applicator by gravity feed methods well known in the art. Such methods do not require application of pressure to the walls of the container.

In an embodiment, the applicator is manufactured with its opening covered by a metal foil or other similar construction which closes this opening until the device is ready for use. The opening is then reinstated by use of a pin or similar device which punctures the covering.

Such devices for intermittent use enable multiple uses of the topical composition at different points in time by the same individual.

In container-applicator devices suitable for repeated intermittent uses, the topical composition is stored at ambient conditions and is selected to be bacteriostatic (see, for example, U.S. Pat. No. 3,527,224). When the selected composition is bacteriostatic, prolonged storage at ambient conditions can be achieved without regard to the sterility of the formulation because there is no adverse buildup of bacteria during storage.

The reservoir of the container-applicator device may be both air-tight and watertight, and keeps the media within free from contaminants. The reservoir may contain a desiccant material to keep the media free of water. Reservoirs may be of any shape, although shapes which provide for a smooth internal flow of media, such as cylindrical or conical shapes. The size of the reservoir may vary within a wide range, but is slightly larger than the volume of composition which will be placed inside the reservoir to minimize the amount of gas within the reservoir. The reservoir may be made from any of a variety of medical grade materials, such as plastics, excluding glass. Pharmaceutical agents of the topical composition suffer from caking when stored in glass reservoir. The reservoir may be rigid, collapsible, or compressible. Use of a compressible or collapsible reservoir allows the user to have greater control over the rate at which the composition is expressed, as exertion of pressure on a compressible or collapsible reservoir would place a force on the on the composition causing it to flow at a faster rate than it would in the absence of such pressure. The compressible or collapsible reservoir design is especially for the topical composition in the form of gel, for which the force of gravity may not be strong enough to cause a flow through an applicator sufficient to treat Epistaxis. Collapsible reservoirs which retain their collapsed shape have the additional advantage of reducing the amount of air which enters the reservoir following use. This advantage of collapsible containers is of greater importance in multiple-use (reusable) devices, wherein media is kept relatively free of potential contaminants between uses.

Applicator tips can be of any of a number of shapes, sizes, and configurations. They may be fairly rigid and may be made out of any material which is compatible with the media formulation, e.g., plastic, excluding glass. The choice of a proper applicator tip for a given application will depend on factors such as the viscosity of the composition, the desired application rate of the composition, the nature of the Epistaxis disorder, and its severity.

The container-applicators of the present invention may be either single-use or multiple-use devices. A container or reservoir containing enough topical composition for multiple applications may be configured to accommodate replaceable tips. In such an embodiment, at the place whereon the replaceable tips connect with the reservoir, the reservoir would have a means such as a valve, septum or sealing gasket which allows the reservoir to be sealed in the absence of an applicator tip. Placing an applicator tip on the reservoir would cause the valve to open, allowing composition to flow out from the reservoir. In this manner, one reservoir containing enough composition for several applications could be used over a period of hours, days or weeks. This embodiment would also allow the user to use one reservoir with applicator tips of varying shapes and sizes chosen to best accommodate the Epistaxis disorder during the healing process. In an embodiment, there are provided nasal sprays/aerosols for the treatment and prevention of Epistaxis (see Examples 8-11).

The nasal sprays/aerosols of this disclosure are suspensions of the pharmaceutical active agents selected from the group consisting of vasoconstrictors, antifibrinolytics and optionally anti-inflammatory agents in at least one HFA (hydrofluoroalkane) containing a film forming agent. As the aerosol is intended for local topical use in the nostril and not for inhalation to the lungs, the nozzle is best designed for delivering a wide plume of aerosol, to be deposited laterally on the nostril walls.

The nasal sprays of this disclosure may be metered dose nasal spray aerosols formulated with HFAs, aqueous nasal sprays or dry powder nasal sprays.

The compositions in the nasal sprays may be delivered in metered doses, also named actuations or "puffs'. A number of actuations (puffs) per day from a metered dose aerosol may be needed for the treatment and prevention of Epistaxis, according to doctor's instructions

After evaporation of the HFA(s), the compositions leave on the nostril's surface a flexible and durable film which contains therapeutically effective doses of the active pharmaceutical ingredient(s). These active ingredients are delivered slowly over a period of time, affording an extended release effect and protection against nosebleeds. The film obtained affords in addition to the therapeutic effect of the active ingredients, also a physical occlusive effect.

The HFAs are selected from the group of FDA-approved hydrofluoroalkanes, including 1,1,1,2-tetrafluoroethane (HFA 134a), 1,1, 1,2,3, 3,3-heptafluoro-n-propane (HFA 227) and combinations thereof.

In some embodiments, the composition of the present invention is a HFA nasal spray/aerosol with a metering valve comprising:

(i) from 0.025% w/w to 2% w/w micronised phenylephrine hydrochloride;

(ii) from 3% w/w to 10% w/w micronised tranexamic acid;

(iii) from 15% w/w to 30% w/w trimethylsiloxysilicate powder; and

(iv) 50%) w/w to 75%) w/w 1,1,1 ,2-tetrafluoroethane.

Uses The present invention provides compositions which are useful for effectively treating a variety of Epistaxis disorders caused by injury to the nose, hemophilia, upper respiratory infection, hypertension, antiplatelet medication, foreign body, insufflated drugs, barotrauma, nasal surgery, nasal sprays, allergic reactions or combinations thereof.

The composition is applied to the Epistaxis affected nostril under conditions suitable for film formation of the composition so as to form a protective coating and typically under non-sterile conditions. In general, sufficient amounts of topical composition are employed to cover the entire affected mucosal surface area. The coating is extended by at least about 1 centimeter and by at least about 5 centimeters beyond the affected surface area.

The term "therapeutically effective amount" as used herein means an amount of the pharmaceutical agent which is sufficient to provide a beneficial effect to the subject to which the pharmaceutical agent is administered. More specifically, a therapeutically effective amount means an amount of the pharmaceutical agent effective to alleviate or ameliorate the symptoms of an Epistaxis disorder of the subject being treated.

As the topical disorders are treated with topical compositions of certain fixed concentrations, reference is made herein to "therapeutically effective concentration".

After an initial layer of topical composition has been applied and the solvent has evaporated, providing an initial dried film coating, a second layer may be applied over the initial film. Additional amounts of topical composition can be applied as needed.

In an embodiment, a topical composition is employed to form a coating of less than about 0.5 mm thick and more of at least about 0.1 mm thick. Such coatings can be formed by applying, for example, about 0.02 ml of topical composition per square centimeter of affected surface area.

In general, the particular length of time required for film formation will vary depending on factors such as the amount of composition applied, the temperature of the mucosal area, the moisture content of the surface area for composition application, and the like. However, in an embodiment, film formation is generally complete within about 10 to about 60 seconds. During this period, the person to whom application of the topical composition has been made minimizes actions and body movements thus allowing the composition to form a dried film coating. The topical compositions of the present invention typically act at temperatures between room temperature (20° C) and body temperature (37° C). The dried films are conformable and comfortable and may be elastic and flexible, and do not irritate the skin and mucous membrane during the application and in use after drying. The dried films are substantially painless and easily removable substantially without pain. The dried films formed from the topical compositions are also substantially non-water sensitive and waterproof. The dried films formed from the topical compositions comprise finely- dispersed pharmaceutical ingredients, which can be gradually released to the adhesion area.

The compositions of the present invention are applicable to both human patients and to non-human mammalian subjects such as in veterinary use, for example for treatment of canine, feline, equine, bovine, porcine and primate species.
