Description

CGRP ANTAGONISTS FOR TREATING SKIN CONDITIONS CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to United States Provisional patent application number 63/240,071, filed September 2, 2021, which is hereby incorporated by reference in its entirety. FIELD OF THE DISCLOSURE Provided for are methods of treating skin conditions with one or more calcitonin gene-related peptide (CGRP) receptor antagonists and/or pharmaceutical compositions thereof. Such methods are useful for treating, ameliorating, alleviating, providing for prophylaxis or prevention of, halting the progression of, and/or reducing the risk of skin conditions in a mammalian subject, such as a human. In particular, CGRP receptor antagonists such as those according to Formula I, Formula II, and/or Formula III as described herein are useful in methods of treating skin conditions in a subject in need thereof. BACKGROUND OF THE DISCLOSURE Redness, rosacea, flushes, and erythema are examples of skin conditions or disorders characterized partly by a vasoactive component that results in aberrant subcutaneous vasodilation and chronic inflammation. Some symptoms may be temporary (transient) or sporadic while others may be long-term (nontransient). Rosacea may present in multiple forms, including erythematotelangiectatic, papulopustular, phymatous, and ocular. Erythematotelangiectatic rosacea is characterized by prolonged central facial flushing and persistent central facial erythema, with or without telangiectasia. The papulopustular variety is characterized by central facial erythema that is persistent and accompanied by facial papules or pustules. Phymatous rosacea develops slowly over time and results in thickened and irregular skin, often on the nose, chin, cheeks, or forehead. Ocular rosacea is characterized by several potential symptoms such as burning, stinging, and/or itching of the eye(s), blurred vision or photosensitivity, and telangiectasia of the sclera as well as periorbital edema. The subcutaneous vasodilation associated with redness, rosacea, flushes, erythema, and other skin conditions is thought to involve a neurogenic component involving overexpression of neuropeptides such as calcitonin gene-related peptide (CGRP). CGRP is a naturally occurring 37-amino-acid peptide first identified in 1982 (Amara, S. G. et al, Science 1982, 298, 240-244). Two forms of the peptide are expressed (αCGRP and βCGRP) which differ by one and three amino acids in rats and humans, respectively. The peptide is widely distributed in both the peripheral (PNS) and central nervous system (CNS), principally localized in sensory afferent and central neurons, and displays a number of biological effects, including vasodilation. When released from the cell, CGRP binds to specific cell surface G protein- coupled receptors and exerts its biological action predominantly by activation of intracellular adenylate cyclase (Poyner, D. R. et al, Br J Pharmacol 1992, 105, 441-7; Van Valen, F. et al, Neurosci Lett 1990, 119, 195-8.). Two classes of CGRP receptors, CGRP1 and CGRP2, have been proposed based on the antagonist properties of the peptide fragment CGRP(8-37) and the ability of linear analogues of CGRP to activate CGRP2 receptors (Juaneda, C. et al. TiPS 2000, 21, 432-438). However, there is lack of molecular evidence for the CGRP2 receptor (Brain, S. D. et al, TiPS 2002, 23, 51- 53). The CGRP1 receptor has three components: (i) a 7 transmembrane calcitonin receptor-like receptor (CRLR); (ii) the single transmembrane receptor activity modifying protein type one (RAMP1); and (iii) the intracellular receptor component protein (RCP) (Evans B. N. et al., J Biol. Chem. 2000, 275, 31438-43). RAMP 1 is required for transport of CRLR to the plasma membrane and for ligand binding to the CGRP-receptor (McLatchie, L. M. et al, Nature 1998, 393, 333-339). RCP is required for signal transduction (Evans B. N. et al., J Biol. Chem.2000, 275, 31438-43). There are known species-specific differences in binding of small molecule antagonists to the CGRP-receptor with typically greater affinity seen for antagonism of the human receptor than for other species (Brain, S. D. et al, TiPS 2002, 23, 51-53). The amino acid sequence of RAMP1 determines the species selectivity, in particular, the amino acid residue Trp74 is responsible for the phenotype of the human receptor (Mallee et al. J Biol Chem 2002, 277, 14294-8). Inhibitors at the receptor level to CGRP are herein postulated to be useful in pathophysiologic conditions where excessive CGRP receptor activation has occurred. Some of these include neurogenic vasodilation, neurogenic inflammation, migraine, cluster headache and other headaches, thermal injury, circulatory shock, and asthma, as well as various skin conditions having a neurogenic component including psoriasis, redness, rosatia, discrete erythema, flushing, menopausal flushing, rash, and hyperseborrhoea. CGRP antagonists or inhibitors are also contemplated to be useful in subjective sensations of itching, pruritus, sensations of burning or heating, sensations of stinging, tingling, discomfort, tightness, and other such sensations having either a neurogenic component or a neurogenic origin. CGRP antagonists have shown efficacy in human clinical trials. See Davis C D, Xu C. Curr Top Med. Chem.20088(16):1468-79; Benemei S, Nicoletti P, Capone J G, Geppetti P.

DETAILED DESCRIPTION OF THE DISCLOSURE Overexpression of CGRP has been associated with skin conditions such as redness, rosacea, flushes, and erythema. The disclosure provides for methods to treat, ameliorate, and/or prevent one or more skin conditions including, but not limited to, redness, rosacea, flushes, and erythema, with compounds and therapeutic or pharmaceutical compositions that inhibit the CGRP receptor. Inhibition of the CGRP receptor with one or more CGRP receptor antagonists may prevent symptoms or disease associated with overexpression of CGRP, including redness, rosacea, flushes, and erythema. Redness, rosacea, flushes, and erythema, among other skin conditions, may be triggered in part by exposure to extreme temperatures, strenuous exercise, heat from sunlight, sunburn, stress, anxiety, alcohol, caffeine, foods high in histamines, and spicy foods. Rosacea may be triggered by topical irritants or medications, including microdermabrasion, chemical peels, isotretinoin, benzoyl peroxide, tretinoin, and topical steroids. In some embodiments, methods of treating, ameliorating, and/or preventing redness, rosacea, flushes, and erythema with a CGRP receptor antagonist may improve a patient’s tolerance to these triggers or risk factors. In some embodiments, methods of treating, ameliorating, and/or preventing redness, rosacea, flushes, and erythema or other skin conditions with a CGRP receptor antagonist further comprise avoiding or limiting triggers or risk factors. Another aspect of the disclosure relates to a method of treatment using combinations of any of Formula I, Formula II, or Formula III with one or more agents selected from ivermectin, azelaic acid, metronidazole, brimonidine, oxymetazoline, xylometazoline, doxycycline, tetracycline and isoretinoin. In some embodiments, methods of treatment may also comprise limiting of exposure to sunlight, or laser therapy. It can be appreciated that a CGRP receptor antagonist may be used alone or in combination with any known treatment in order to treat, ameliorate, and/or prevent redness, rosacea, flushes, and erythema, other skin conditions, or symptoms associated therewith.

In reference to a particular condition, “treating” and its derivatives are inclusive of several meanings, including (1) to alleviate one or more symptoms, effects, or side effects associated with the condition, (2) to ameliorate the condition and/or one or more of the biological manifestations or underlying causes of the condition, (3) to interfere with one or more of the biological manifestations or underlying causes of the condition or with one or more points in the biological cascade(s) associated with the condition, (4) to slow the progression of, or arrest the development of, the condition or of one or more of the biological manifestations of the condition, (5) to prevent or reduce the risk of a subject developing the condition, in some cases prophylactically when the subject has one or more risk factors for the condition (6) to cause regression of the condition, or improvement or reversal of, the biological manifestations or underlying causes of the conditions. It can be appreciated that “treating” may encompass one or more of these meanings simultaneously and that a subject’s condition may change over time or throughout the course of treatment such that the meaning of “treating” as applied to a given subject may change over time or throughout the course of treatment. “Treating” as used herein may also refer to any beneficial effect of administering a CGRP receptor antagonist compound and/or a pharmaceutical composition comprising a CGRP receptor antagonist to a subject or patient having or being at risk for developing one or more skin conditions. “Treating” therefore may encompass alleviating one or more skin conditions and/or the symptoms of one or more skin conditions, prophylaxis or prevention of one or more skin conditions or of the worsening of one or more skin conditions, and reducing the risk that a subject or patient may develop new or worsening skin conditions. “Treatment” may be in combination with other therapies or alone. The term “AUC” (area under the curve) typically refers to a total amount of drug absorbed or exposed to a subject. Generally , AUC may be obtained from mathematical method in a plot of drug concentration in the subject over time until the concentration is negligible . The term “ AUC ” may also refer to partial AUC at specified time intervals. The AUC may be determined within a certain time period (such as from time 0 to time t; AUC0-t) or may be extrapolated from the last measured point to the point where drug concentration in the subject is zero (AUCinf). The term "C_max” refers to a maximum concentration of a drug in blood , serum , a specified compartment or test area of a subject after administration of a dose or between administration of a first dose and administration of a second dose. The term Cmax could also refer to dose normalized ratios, if specified. The term “T_max” refers to a time or period after administration of a drug when the maximum concentration (Cmax) is reached in blood, serum, a specified compartment or test area of a subject. The term “dosing interval” refers to the amount of time that elapses between multiple doses of a formulation disclosed herein being administered to a subject. Dosing interval can thus be indicated as ranges. The term “dosing frequency” refers to the frequency of administering doses of a formulation disclosed herein in a given time. Dosing frequency can be indicated as the number of doses per a given time, e.g., once a day (daily), twice a day (twice daily), once a week (weekly) or once in two weeks, etc. For the purposes of the present disclosure, the term “excipient” and “carrier” are used interchangeably throughout the disclosure and said terms are defined herein as, “ingredients which are used in the practice of formulating a safe and effective pharmaceutical composition.” Examples The following examples further describe and demonstrate embodiments within the scope of the present disclosure.

Example 5 – Combination Treatments for Treating Skin Conditions Some patients having active symptoms of one or more skin conditions can be treated in a study with one or more of an oral, topical, intranasal and/or injectable pharmaceutical composition according to Examples 1 – 4 simultaneously, alternatively, or initially via one route initially in a first treatment phase followed by a second route in a second treatment phase. In a first subset of patients, a local topical treatment can be applied in a first treatment phase followed by an oral, intranasal, or injectable systemic treatment in a second treatment phase following the first. The local topical treatment, i.e. the first treatment phase, can be applied for a set period of time or until a change or improvement of symptoms is observed, after which a second treatment phase can be applied. The systemic oral, intranasal, or injectable treatment, i.e. the second treatment phase, would then be applied either i) until symptoms have been reduced or cleared and/or ii) for a prolonged period for prophylaxis, prevention, and reduction in the risk that the patient has further symptom flares. In a second subset of patients, systemic oral, intranasal, or injectable treatment can be applied in a first treatment phase followed by a topical local treatment in a second treatment phase following the first. The systemic oral, intranasal, or injectable, i.e. the first treatment phase, can be applied for a set period of time or until a change or improvement of symptoms is observed, after which a second treatment phase can be applied. The local topical treatment, i.e. the second treatment phase, would then be applied either i) until symptoms have been reduced or cleared and/or ii) for a prolonged period for prophylaxis, prevention, and reduction in the risk that the patient has further symptom flares. In a third subset of patients, systemic oral, intranasal, or injectable treatment can be applied concurrently with a topical local treatment. Within the subset, after a set period of time or after improvement of symptoms is observed, some patients can discontinue the local topical treatment and continue receiving the systemic oral, intranasal, or injectable treatment either i) until symptoms have been reduced or cleared and/or ii) for a prolonged period for prophylaxis, prevention, and reduction in the risk that the patient has further symptom flares. For other patients within the subset, after a set period of time or after improvement of symptoms is observed, some patients can discontinue the oral, intranasal, or injectable systemic treatment and continue receiving the local topical treatment either i) until symptoms have been reduced or cleared and/or ii) for a prolonged period for prophylaxis, prevention, and reduction in the risk that the patient has further symptom flares. It is expected that such combination therapies can treat one or more skin conditions with varying degrees of success in different patients having different types of skin conditions and symptoms, and that, guided by these developed therapies, physicians can identify an effective course of treatment for one or more skin conditions using the compounds, compositions, and methods of the present disclosure.
