Description
Use of Topical Compositions for the Control of Microbial Diseases of the
Nail
The present invention relates to the use of copper silicate for treating and preventing microbial infections and diseases and in particular fungal diseases of the nail such as onychomycosis. The present invention also relates to copper silicate compositions adapted for topical administration.
NB Microbial diseases of the nail are a considerable public health concern. Whilst there are diseases and disorders caused by bacteria, the most prevalent and - clinically significant nail diseases are caused by fungi.
Onychomycosis is a fungal disease of nails caused by a range of fungi, principally dermatophytes - Trichophyton species such as Trichophyton mentagrophytes and
Trichophyton rubrum, but also Trichophyton megninii, Trichophyton schoenleinii and Trichophyton tonsurans and Candida species, such as C. albicans. Infection is of the nail unit (the nail matrix, bed or plate) and although not life threatening it can cause inconvenience, pain, discomfort and sometimes serious physical and occupational limitations.
There is presently a range of oral medications available for treating onychomycosis. However, these are generally expensive, suffer from limited effectiveness, require close monitoring from practitioners and can cause serious side effects such as liver and heart damage. :
Whilst there is a clear need for an effective topical agent for treating onychomycosis, the agents presently available have limited efficacy. The most widely used topical agent is Penlac®. However, the clinical studies concerning this agent report low efficacy.
The main difficulty faced when developing an effective topical agent for the nail is that the nail plate is thick, hard and dense, and represents a formidable barrier for drugs preventing them from reaching the infection site in a therapeutically required quantity. Adding to this problem is the fact that onychomycosis is associated with a thickening of the nail plate. To overcome this problem prior art topical agents for treating onychomycosis have incorporated agents that increase the permeability of the nail plate. However, these topical agents contain multiple agents i.e. a softener and an anti-fungal and thus are refatively expensive to produce. Furthermore, such agents have met with limited success. )
The present invention seeks to overcome the above problems by providing a safe and effective topical anti-microbial that is capable of treating microbial infections of the nail.
The present invention provides a method of treating or preventing microbial infection of a subject's nail, the method comprising the step of topically administering to said nail an effective amount of copper silicate.
The infections treated or prevented by the method of the present invention may manifest themselves into disease states that may also be treated according to the present invention. Thus, the present invention also provides a method of treating or preventing a microbial disease of a subject's nail, the method comprising the step of topically administering to the nail an effective amount of copper silicate.
The present invention also provides a composition adapted for topical administration comprising an anti-microbial effective amount of copper silicate.

Figure 6 is a series of photos showing the time course of treatment (Day 0: untreated, week 6, week 26 and week 12 - post-treatment) of a dermatophyte infection of a sixth subject's nail, according to one exemplary method of the present invention; and
Figure 7 is a series of photos showing the extended time course of treatment (Day 0: untreated, week 6, week 26 and week 12 - post-treatment) of a dermatophyte infection of the second subject's nail, according to one exemplary method of the present invention.
The present invention provides a method of treating or preventing microbial infection of a subject's nail, the method comprising the step of topically administering to said nail an effective amount of copper silicate.
For the purposes of the present invention the term “topically administering” includes, but is not limited to, application through the nail plate with a device adapted to perforate the nail plate and application between the nail plate and nail bed with a device adapted to be inserted therebetween. :
For the purposes of the present invention the term “nail” refers to one or more of the elements of the nail unit (the nail matrix, bed or plate) and also includes toe and fingernails and animal nail like features such as hooves, trotters and claws.
Surprisingly, it has been found that the copper silicate administered to a nail according to the present invention delivers either an effective anti-microbial dose to the infected area or a dose sufficient to prevent infection with a microbial nail pathogen. In this regard, the applicant has discovered that upon administration of 10 . the copper silicate to the nail, therapeutically effective amounts of the copper are able to reach the site of infection. The precise mode of this effect has not been established conclusively, but the Applicant is aware that the copper silicate persists at the site of application and/or the site of infection.
Topical administration may be achieved in any one of a number of ways.
Preferably, the compound is applied to the nail by painting, wiping, dabbing or spraying the nail with the compound. Alternatively, topical administration may be achieved by submerging the nail in a copper silicate solution or contacting the nail with a means for dispensing an effective amount of copper silicate. Dispensing means can be varied and include slow release carriers and materials impregnated with copper silicate such as patches, bandages, cotton wool and gauze.
Preferably, the dispensing means is adapted to be removably fixed to the nail to deliver the copper silicate over a predetermined time and/or at a predetermined dose.
The methods of the present invention may be used to treat microbial such as fungal, infection in any animal and more particularly any mammal. However, preferably, the subject is human. Thus the present invention also provides for the use of copper silicate for preparing a medicament for treating microbial infections such as fungal infections including onychomycosis.
it is common for nails to be infected with a range of microbes such as bacteria and fungi (including yeast). Thus, the microbial infection may be bacterial.
However, the method of the present invention is particularly useful for treating fungal infections. .
The amount of copper silicate applied in the method of the present invention will be sufficient to effectively treat or prevent the infection and thus will necessarily vary depending at least on the severity and type of the infection, the strength of the composition and the manner in which individual patients respond to the treatment. However, preferably a composition containing 1-100 pg of copper is applied to each infected nail, more preferably a composition containing 2-50 pg of copper is applied to each infected nail and even more preferably, a composition containing 5-20 ug of copper is applied to each infected nail. In one particular form of the invention a composition containing at least about 10 pg of copper is applied to each infected nail.
Similarly, the frequency with which, and the duration for which, the copper silicate is applied will be sufficient to effectively treat or prevent the infection and thus will also vary depending at least on the severity and type of infection, the strength of the composition and the manner in which individual patients respond to the treatment. Preferably, the copper silicate is applied at least once, twice or three times a day for at least 1, 3, 6, 12, 26, 30, 40, 45, 48 or 52 weeks. Alternatively, it may be applied once every 2 — 14 days for as long as necessary to treat or prevent infection.
Thus, the present invention also provides a method of treating or preventing microbial infection of a subject's nail, the method comprising the step of repeatedly topically administering to said nail an effective amount of copper silicate.
As indicated above the method of the present invention may be applied to treat fungal infections. In this regard, fungal infections which may be treated according to the present invention include infections from dermatophytes, such as
Trichophyton species including Trichophyton mentagrophytes (including varieties mentagrophytes and interdigitales), Trichophyton rubrum, Trichophyton megninii,
Trichophyton schoenleinii, Trichophyton tonsurans; yeasts, such as Candida species, most notably Candida albicans, Candida glabrata, Candida ciferrii,
Microsporum species including Microsporum canis and Microsporum gypseum;,
Malassezia species including Malassezia furfur and Malassezia sympodialis;
Epidermophyton species such as Epidermophyton floccosum; Scopularosis species, Acremonium species and Aspergillus species.
Thus, the present invention also provides a method of treating or preventing infection of a subject's nail with one or more of. dermatophytes, such as
Trichophyton species including Trichophyton mentagrophytes (including varieties ~mentagrophytes and interdigitales), Trichophyton rubrum, Trichophyton megninii,
Trichophyton schoenleinii, Trichophyton tonsurans; yeasts, such as Candida species, most notably Candida albicans, Candida glabrata, Candida ciferrii,
Microsporum species including Microsporum canis and Microsporum gypseum,
Malassezia species including Malassezia furfur and Malassezia sympodialis;
Epidermophyton species such as Epidermophyton floccosum; Scopularosis species; Acremonium species and Aspergillus species, the method comprising ~ the step of topically administering to said nail an effective amount of copper silicate.
Fungal nail infections that may be treated using the methods of the present : invention are usually characterized by tarnished white, yellowed, or blackened nails. The nails may pull away from the pink nail bed along the sides or outer edges, and infections are usually exacerbated by hot, damp conditions, such as inside footwear or in environments where hands or feet are continually exposed to moisture. The fungal infections can spread from toe to toe, foot to foot, and foot fo hand.
Methods of treating or preventing microbial diseases
The present invention also provides a method of treating or preventing a microbial disease of a subject's nail, the method comprising the step of topically administering to the nail an effective amount of copper silicate.
Whilst the method of the present invention may be applied to treat a wide range of microbial diseases of the nail it is particularly useful for treating fungal diseases of the nail. Thus, the present invention also provides a method of treating or preventing a fungal disease of a subject's nail, the method comprising the step of topically administering to the nail an effective amount of copper silicate.
Specific fungal diseases that can be treated by the methods of the present invention include onychomycosis such as distal subungual onychomycosis, superficial white onychomycosis, proximal white subungual onychomycosis; total secondary dystrophic onychomycosis; and total dystrophic primary onychomycosis.
In some situations, it may be desirable to combine the method of treating or preventing a fungal disease according to the present invention with other therapies. Thus, the present invention also provides a method of treating or preventing a fungal disease of a subject's nail, the method comprising the step(s) of topically administering to said nail an effective amount of copper silicate and (ii) administering to said subject an effective amount of at least one other anti-fungal agent.
The other anti-fungal agent may be varied and includes, for example, one or more orally administrable anti-fungal agents selected from the group consisting of: miconazole, ketoconazole, itraconazole, fluconazole, econazole, ciclopirox, oxiconazole, clotrimazole, terbinafine, naftifine, pharmaceutically acceptable salts thereof and stereoisomers thereof, Lamisil™, Sporanox™ and Diflucan™.
The present invention also provides for the use of copper silicate for preparing a medicament for treating or preventing a disease caused by a fungal infection.
Topical Formulations
The present invention also provides a composition adapted for topical administration to a nail comprising an anti-microbial effective amount of copper silicate.
~-8~
The form of the composition of the present invention may also be varied provided it retains its anti-microbial properties. Preferably, the composition is a solution.
However, the composition may also be in solid form provided it is properly formulated. In this regard, the composition could comprise copper silicate in the form of a micronized solid such as chrysocolia.
When the copper silicate is provided in the form of a solution, it preferably is provided as an aqueous acidified solution. Acidified solutions are particularly preferred because copper silicate is more soluble at acidic pH. Particularly preferred pHs are 3-6, 4-6 and 5-6. In one example, the copper silicate is prepared according to the methods described and claimed in US patent 5,474,972.
The composition adapted for topical administration may be in the form of any one of the following: solution, lotion, suspension, emulsion, cream, gel, ointment, liniment and salve. Particularly preferred forms are ointments, creams or gels.
Ointments generally are prepared using either (1) an oleaginous base, i.e., one consisting of fixed oils or hydrocarbons, such as white petroleum or mineral oil, or (2) an absorbent base, ie., one consisting of an anhydrous substance or substances that can absorb water, for example anhydrous lanolin. Customarily, following formation of the base, whether oleaginous or absorbent, the active ingredient is added to an amount affording the desired concentration.
Creams are oil/water emulsions. They consist of an oil phase (internal phase), comprising typically fixed oils, hydrocarbons and the like, waxes, petroleum, mineral oil and the like and an aqueous phase (continuous phase), comprising water and any water-soluble substances, such as added salts. The two phases are stabilised by use of an emulsifying agent, for example, a surface active agent, such as sodium lauryl sulfate; hydrophilic colloids, such as acacia colloidal clays, veegum and the like. For the purposes of the present invention, the compound may be added to the water phase prior to formation of the emulsion, in an amount to achieve the desired concentration.
Gels comprise a base selected from an oleaginous base, water, or an emulsion- suspension base. To the base is added a gelling agent that forms a matrix in the base, increasing its viscosity. Examples of gelling agents are hydroxypropyl cellulose, acrylic acid polymers and the like. For the purposes of the present invention the compound may be added to the formulation at the desired concentration at a point preceding addition of the gelling agent.
The compositions of the present invention may be produced by dissolving or combining the copper silicate in an aqueous or non-aqueous carrier. In general, any liquid, cream, or gel, or similar substance that does not appreciably react with the silicate or any other active ingredient that may be introduced and which is non-irritating is suitable. . Thus, the present invention also provides a method of producing copper silicate adapted for topical administration comprising the step of dissolving or combining the copper silicate in an aqueous or non-aqueous topical carrier.
The composition of the present invention may further comprise an auxiliary agent such as any one or more of: preservatives, stabilizers, emulsifiers, wetting agents, fragrances, colouring agents, odour controllers and thickeners such as natural gums.
The concentration of the copper in the composition may be varied depending at least on the severity and type of infection that the composition is to be used to treat or prevent. However, preferably, the concentration of the copper is approximately 100 mg/L — 10 g/L (as Cu). More preferably, the copper concentration is to a final concentration of approximately 1 g/L — 5 all or2g/L-3 g/L (as Cu).
The present invention will now be described with reference to the following examples. The description of the examples is in no way to limit the generality of the preceding description.

Subjects, not already receiving anti-fungal treatment, were assessed for clinical : diagnosis of onychomycosis and photographs and nail clippings were taken.
Those testing positive for onychomycosis were admitted to the trial.
The anti-fungal composition (cream or solution) was applied to the infected nail twice daily for the duration of the treatment.
Estimates of the nail area involved were made during clinical visits and photographs were taken. Nail clippings were collected for “KOH and dermatophyte culture. Subjects were assessed by a clinician for onychomycosis using the following criteria: * “Not effective” is >10% nail involvement with KOH positive and culture : positive; * “Mycological cure” KOH negative and culture negative; “Effectively treated” is <10% nail involvement, with KOH and culture negative; ee gp « “Complete cure” is clinical clearance of the target nail together with negative
KOH and culture.
Results
The results presented hereunder are interim results of a 12 month study.
Patients entered the trial and commenced their treatment at different dates. Of the 18 patients enrolled in the trial, 13 had reached 6 weeks of treatment, and of these, 10 had reached 12 weeks of treatment, at the time of reporting these results. Patients were assessed at 0 (commencement), 6 weeks and 12 weeks. :
The results of these assessments are tabulated befow in Table 3. No differences ; were noted in efficacy between the cream and solution at any of the : assessments.

No adverse reactions have been reported.
S At week 26, 3 patients achieved the primary endpoint of “complete cure” and maintained their status 26 weeks post-treatment at 52 weeks. By 26 weeks post : treatment 4 (22%) patients were “effectively treated”, an increase by one patient over 26 and 39 weeks which only included the 3 “complete cure” patients. “Mycological cure” was achieved in 5 (28%) patients after 26 weeks, but 2 of these had reverted to KOH positive-at 39 weeks. At 52 weeks the “mycological - or cure” rate was 22%. “Mycological change”, or the change from culture positive to culture negative, was : achieved by another 7 patients at weeks 26 and 39. This gave a total of 12 culture negative patients at 26 weeks and 10 at 39 weeks.
In total, 67% of patients were culture negative at the end of treatment, 55% at 13 weeks post-treatment, and 50% (9 patients) at the end of the trial.
The primary and secondary endpoints of “complete cure” and “effective treatment” are both dependent upon the mycological cure rate. “Mycological cure” is defined as both KOH and culture negative, but patients may not become
KOH negative until the diseased nail has grown out. lt is usual for a great toenail to take 12-18 months to totally regrow. At the commencement of this trial, 12 of the 18 patients had >50% of their target nail infected, and of these 7 had cuticle (lunula) involvement. As a result of extensive disease, “mycological cure” and thus “effective treatment” and “complete cure” may not have been achievable by these patients in the time allotted to this study.
The treatment time of 26 weeks is considerably shorter than for most topicals that are applied for a minimum of 48 weeks. It is evident from this trial that patients with >50% of the nail plate diseased would have benefited from an extended treatment time. The results at 26 weeks show that many (50%) had significant clinical improvement with a reduction in the extent of their disease to <50% of the nail plate.
The present invention includes any and all modifications and adaptations apparent to one skilled in the art.
Throughout the specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood
Co to imply the inclusion of a stated integer or group of integers but not the exclusion _ of any other integer or group of integers.
