U

MEIHDB OF TREATING ROSACEA tt TECHNICAL FIELD The present invention relates to methods for the topical treatment of rosacea.

O

CI BACKGROUND OF THE INVENTION Rosacea is a common chronic skin condition characterized by a spectrum of clinical indications including flushing episodes, erythema, telangiectasia, inflammatory papulopustular eruptions resembling acne, and ocular symptoms.

Although accurate incidence data for the U.S. are not available, data obtained in Sweden suggest that some form of rosacea may be present in up to 10% of the average population. Sufferers are mostly of European origin, generally with fair skin and blue eyes. Women are more prone to develop rosacea than men, with flushing episodes and erythema being the most common symptoms found: The etiology of rosacea is unknown, but it is presumed to be a genetically determined anomalous vascular response that develops in the third to sixth decades of life. The hypothesis that the basic pathogenesis of the disease is a flushing disorder is based on several findings. The disease appears to more prevalent in northern climates where cold exposure is experienced more often, and in light-skinned persons in whom flushing is common and sensitivity to sunlight is particularly high. Accordingly, rosacea may represent a type of hypersensitivity reaction disease in which vascular sensitivity is a central mechanism in its etiology. The correlation between sensitive blood vessels and sensitive skin has, however, not yet been determined.

O Epidemiological studies suggest that the regulatory mechanism of blood vessels may Sbe of importance in the onset and development of rosacea. Studies show that 27% of rosacea patients were found to suffer from migraine and 42% from a tendency to flush, both of which represent about twice the level that would typically be found in a I control group.

An etiological role has also been proposed for the Demodex species, mites that Cl normally inhabit human hair follicles and are reported to appear in greater numbers in rosacea patients. A number of dietary factors, for example hot drinks, alcohol, spicy foods, and environmental conditions temperature changes), are well-recognized triggers of the disease. In literature, there are also reports of possible involvement of altered immune function and anomalously low skin surface lipids in the pathogenesis ofrosacea.

The key to successful management of rosacea is early diagnosis and treatment.

Treatment is generally aimed at controlling the symptoms and making the skin look better. At the present time, rosacea cannot be cured, though the frequency of its flareups can be diminished and their severity alleviated. Most cases of rosacea can be controlled with anti-inflammatory medications, combined with the avoidance of lifestyle and environmental factors that may aggravate the disorder in individual cases. Treatment generally works best at improving the pimples and bumps of rosacea: the redness of the skin is harder to treat. Therapeutic agents for inflammatory rosacea conditions are generally classified in two groups: systemic and topical antibiotics; and retinoids. Systemic and topical antibiotics include tetracycline, Smetronidazole, erythromycin, minocycline and clindamycin, but the use of these

O

agents is often accompanied by drug side effects, the development of resistance, and d changes in the normal microbial flora. Retinoids include tretinoin (vitamin A or Sretinoic acid), which is applied topically to inhibit follicular keratinization, and isotretinoin(l 3-cis-retinoic acid), which is administered systemically to suppress 0activity of the sebaceous glands. Retinoids are often irritants and are not advised for individuals with sensitive skin. Retinoids can also be phototoxic and they can induce Sthin and easily bruisable, fragile skin.

Metronidazole (5-methyl-5-nitroimidazole-l-ethanol), an antibacterial, is currently one of the more frequently prescribed treatments for rosacea in the United States. It is available as a topical cream under the name MetrogelTM from Galderma.

Metronidazole is structurally similar to some materials which are believed to be carcinogens and is, in fact, listed by the U.S. Environmental Protection Agency as reasonably anticipated to be a human carcinogen. See Merck Index, 1996, page 1051.

Thus, there is a need for a safe and effective topical treatment of the symptoms of rosacea which not only act quickly and effectively, but which present reduced side effects when compared to the current treatment modalities.

SThe active material is applied topically to the skin at the site of rosacea, or at the site where the patient is prone to exhibit rosacea if the invention is used in a prophylactic/preventive mode. The active material is typically applied to the skin in an amount of from about 0.05 to about 1 mg/cm 2 preferably from about 0.3 to about mg/cm 2 but this can vary depending upon the formulation, the patient and the nature of the specific condition being treated.

The active material may be applied in combination with a topical carrier.

Topical carriers are well known in the art and are described, for example, in U.S.

Patent 6.376.514, Degenhardt, et al., issued April 23, 2002; U.S. Patent 6,380,168, Kubo. et al.. issued April 30, 2002; and U.S. Patent 6,368,831, Maurer, et al., issued April 9. 2002; all of which are incorporated herein by reference. When used with a topical carrier, the active material and the topical carrier together comprise a topical composition. In such topical compositions, the active material generally comprises from about to about 50% of the composition, preferably from about 1% to about of the composition, most preferably from about 2% to about 10% of the composition, with the balance of the composition generally comprising the topical carrier.
