unds of Invention Reduce Dermal Inflammation in Mice after LL-37 Challenge

[0027]Recent studies show a link between triggers of rosacea (including Demodex folliculorum, UV radiation, stress, etc.) and induced cellular and tissue responses. It has been suggested that an altered innate immune response is involved in the disease pathogenesis (Yamasaki, K and Gallo, R., J Dermatol Sci., 55: 77-81, 2009)

[0028]Triggering the innate immune system normally results in a controlled increase in cytokines and antimicrobial peptides, such as cathelicidins, in the skin. Some forms of cathelicidin peptides have the capacity to be both proinflammatory and vasoactive. Individuals with rosacea not only express high levels of cathelicidin, but also produce forms of cathelicidin peptides which promote leukocyte chemotaxis, angiogenesis, and expression of extracellular matrix components. It has been shown that injection of these peptides into the skin of mice results in skin inflammation resembling patho...

of the Invention Reduce Dermal Levels of TGFb1 Following Wound-Induced Inflammation in Minipigs

[0037]The purpose of this study was to evaluate the topical effects of axitinib, nintedanib, sorafenib and lenvatinib when administered via intradermal injection to the dorsal skin along linear incisions of minipigs. Linear incisional wound was made to elicit inflammatory and wound healing process in the skin. After dosing, animals were observed postdose for 9 days to assess the levels of TGFb1 expressions in the skin.

[0038]Three male Gottingen Minipigs® dosed once via intradermal injection along the edges of each of the linear incision wound sites for each animal (wounds on the dorsum, perpendicular to the spine, approximately 3 cm in length and 3 cm distance from the spine). Each incisional wound received approximately 16 mg of the test compound intradermally once along both sides of the linear wound.

[0039]On days of 4, 7, and 9 post-dosing, one 4 mm dermal punch biopsy was collected for...

of the Invention Reduce the Expression of TGF Beta in a Rabbit Ear Injury Model

[0043]The objective of this study was to examine the effect of test compounds on wound healing and TGF beta expression after dermal injury in a rabbit ear hypertrophic scar model.

[0044]In New Zealand white rabbits, maintained under a surgical plane of anesthesia, trauma stimulation of the skin on the ventral surface of both ears is initiated on Day 1. Trauma sites are evaluated on Days 8, 15, 22, 29, 36, and 43. On days 15 and 29, each site is dosed with test compounds (e.g., 1% w / w, 100 μl) by intradermal or intralesional injections.

[0045]Animals are euthanized on Day 43, and the trauma sites are harvested and frozen for TGF beta analysis using quantitative RT-PCR (qRT-PCR) (e.g., A. K. Johnson et al., Dev. Comp. Immunol., 2006; 30(5): 473-84). TGF beta1 mRNA expression levels in treated trauma samples are compared to the expression level in the untreated trauma sample.

[0046]As shown in FIG. 6, the mean ...

Abstract

A pharmaceutical composition for prevention or treatment of a disease or disorder characterized by chronic inflammation, with associated angiogenesis and fibrosis, wherein the disease or disorder is selected from the group consisting of rosacea, psoriasis, erythema multiforme, bullous pemphigoid, hereditary hemorrhagic telangiectasia, rheumatoid arthritis, atopic dermatitis, and dermal wound healing. The pharmaceutical composition includes at least one multi-kinase inhibitor selected from the group consisting of axitinib, nintedanib, and lenvatinib.

Description

FIELD OF INVENTION[0001]This invention relates to methods of prevention and treatment of diseases or disorders characterized by chronic inflammation, with associated angiogenesis and fibrosis, such as psoriasis, rosacea, erythema multiforme, bullous pemphigoid, hereditary hemorrhagic telangiectasia, rheumatoid arthritis, atopic dermatitis, and dermal wound healing.BACKGROUND OF THE INVENTION[0002]Chronic inflammation, with associated angiogenesis and fibrosis, is a characteristic of many diseases, such as psoriasis, rheumatoid arthritis and rosacea. Although these broad pathologies are contributing factors, the underlying causes of such diseases are often not clear.[0003]For example, the cause of rosacea, which is characterized by facial redness, dilated blood vessels on facial skin, papules, pustules, and swelling, remains unknown. What is known is whatever triggers episodes of flushing and blushing may play a part in the development of rosacea.[0004]Similarly, psoriasis is an auto...
