[0006] The present disclosure is not limited to the specific systems, apparatus, and methods described. The terminology used herein is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope. Such aspects of the present disclosure may be embodied in many different forms. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey its scope to those skilled in the art.

[0007] The present disclosure is not limited in terms of the specific embodiments described in the present disclosure, which are intended as examples of various aspects. As will be apparent to those skilled in the art, many modifications and variations can be made without departing from the spirit and scope thereof. Functionally equivalent methods and apparatuses within the scope of the present disclosure, in addition to those recited herein, will be apparent to those skilled in the art from the foregoing description. Such modifications and variations are intended to be included within the scope of the appended claims. The present disclosure is limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that the present disclosure is not limited to specific methods, reagents, compounds, compositions, or biological systems. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0008] As used herein, the singular forms "a," "an," and "the" include plural references unless the context clearly indicates otherwise. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Nothing in this disclosure is to be construed as an admission that the embodiments described in this disclosure are not entitled to antedate such disclosure by virtue of prior invention. As used herein, the term "comprising" means "including, but not limited to."

[0009] Although various compositions, methods, and devices are described in terms "comprising" (which should be interpreted as meaning "including, but not limited to") various components or steps, the compositions, methods, and devices can also "consist essentially of" or "consist of" the various components and steps, and such terms should be interpreted as defining essentially closed groups of members.

[0010] With respect to the use of virtually any plural and / or singular term herein, one of ordinary skill in the art can translate from plural to singular and / or from singular to plural as appropriate to the context and / or application. Various singular / plural permutations may be expressly provided herein for clarity.

[0011] In general, those skilled in the art will understand that the terms used in this specification, and particularly in the appended claims (e.g., the body of the appended claims), are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including, but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes, but not limited to," etc.). Those skilled in the art will further understand that if a particular number of recitations of the introduced claims are intended, such intention will be expressly set forth in the claims, and in the absence of such recitation, no such intention exists. For example, as an aid to understanding, the following appended claims may use the introductory phrases "at least one" and "one or more" to introduce the recitations of the claims. However, the use of such phrases should not be construed to mean that the introduction of a claim repeat with the indefinite article "a" or "an" limits a particular claim that includes such an introduced claim repeat to embodiments that include only one such repeat, even if the same claim includes the introductory phrase "one or more" or "at least one" and an indefinite article such as "a" or "an" (e.g., "a" and / or "an" should be construed to mean "at least one" or "one or more"); nor should the use of definite articles used at the beginning of a claim. Moreover, even if a particular number of introduced claim repeats is explicitly recited, one of ordinary skill in the art will recognize that such recitation should be construed to mean at least the number recited (e.g., the mere recitation of "two recitations" without other modifiers means at least two recitations or two or more recitations).Furthermore, when a convention similar to "at least one of A, B, and C" is used, such configurations are generally intended in the sense that one of ordinary skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" includes, but is not limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). When a convention similar to "at least one of A, B, or C" is used, such configurations are generally intended in the sense that one of ordinary skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" includes, but is not limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). Those skilled in the art will further appreciate that virtually any conjunctive word and / or phrase presenting two or more alternative terms, whether in the specification, claims, or drawings, should be understood to contemplate the possibility of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" is understood to include the possibilities of "A" or "B," or "A and B."

[0012] In addition, where features or aspects of the disclosure are described in terms of a Markush group, those skilled in the art will recognize that the disclosure is thereby also described in terms of any individual members or subgroups of members of the Markush group.

[0013] All percentages, portions and ratios are based on the total weight of the composition and all measurements made at about 25° C. unless otherwise specified.

[0014] As will be appreciated by those of skill in the art, all ranges disclosed herein encompass all possible subranges and combinations of subranges thereof for any purpose, including in terms of providing a written description. Any recited range can be readily recognized as fully descriptive and allowing for the same range to be broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third, and upper third, etc. As will also be appreciated by those of skill in the art, all phrases such as "up to," "at least," etc. refer to ranges that are inclusive of the recited numbers and that can then be broken down into subranges as described above. Finally, as will be appreciated by those of skill in the art, ranges include individual members. Thus, for example, a group having 1-3 cells refers to a group having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to a group having 1, 2, 3, 4, 5 cells, etc.

[0015] The term "about" as used herein refers to variations in numerical quantities that may occur, for example, due to real-world measurement or handling procedures, due to inadvertent errors in these procedures, due to differences in the manufacture, source, or purity of the composition or reagent, and the like. In general, the term "about" as used herein means greater or smaller than the stated value or range of values ​​by 1 / 10 of the stated value, e.g., ±10%. The term "about" also refers to variations that would be recognized as equivalent by one of ordinary skill in the art, unless they encompass known values ​​implemented by the prior art. Each value or range of values ​​preceded by the term "about" is also intended to encompass embodiments of the stated absolute value or range of values. Quantitative values ​​referred to in this disclosure, whether modified by the term "about", include equivalents to the stated value, e.g., variations in numerical quantities of such values ​​that may occur but are recognized as equivalent by one of ordinary skill in the art. If the context of this disclosure indicates otherwise or is inconsistent with such an interpretation, the above interpretation can be modified as would be readily apparent to one of ordinary skill in the art. For example, in a list of numerical values ​​such as "about 49, about 50, about 55," "about 50" means less than half the interval between the preceding and succeeding values, e.g., a range extending from more than 49.5 to less than 52.5. Furthermore, expressions less than "about" a value or greater than "about" a value should be understood in light of the definition of the term "about" provided herein.

[0016] As used herein, the term "substantially free" indicates that the particular material being referenced is present in an amount of not more than 10% by weight or volume of the total composition.

[0017] When a range of values ​​is listed, each intervening value between the upper and lower limits of that range, as well as other stated or intervening values ​​within that listed range, are intended to be encompassed by the disclosure. For example, if a range of 1 μm to 8 μm is listed, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, and 7 μm are also intended to be expressly disclosed, as are ranges of values ​​equal to or greater than 1 μm and ranges of values ​​equal to or less than 8 μm.

[0018] The terms "patient" and "subject" are interchangeable and may be taken to mean any living organism that may be treated with the compounds of the present invention. Thus, the terms "patient" and "subject" may include, but are not limited to, any non-human mammal, primate, or human. In some embodiments, the "patient" or "subject" is a mammal, such as a mouse, rat, other rodent, rabbit, dog, cat, pig, cow, sheep, horse, primate, or human. In some embodiments, the patient or subject is an adult, child, or infant. In some embodiments, the patient or subject is a human.

[0019] As used in the specification, the term "pediatric subject" or "pediatric patient" is used to refer to a subject who is a male or female aged from about 6 years to about 16 years and 11 months, a male or female aged from about 12 years to about 16 years and 11 months, a male or female under the age of 18, or a male or female under the age of 12.

[0025] As used herein, the term "perilesional" or "perilesional" refers to administration of a therapeutic agent or application of a microneedle patch adjacent to a skin lesion. Perilesional administration can be within the range of 0.2 mm to 1000 mm.

[0026] As used herein, the term "intralesional" or "intralesional" refers to the administration of a therapeutic agent or the application of a microneedle patch directly to a skin lesion. The term "intralesional" can be used interchangeably with "applied directly to a skin lesion."

[0027] The terms "treat", "treated" or "treating" as used herein refer to both therapeutic treatment and prophylactic or preventative measures, the purpose of which is to reduce the frequency or delay the onset of symptoms of a medical condition, improve the texture, appearance, color, feel, or hydration of the intended tissue treatment area of ​​the tissue surface in a subject compared to a subject not administered the compound or composition, or otherwise obtain a beneficial or desired clinical result. For purposes of the present invention, beneficial or desired clinical results include, but are not limited to, reversal, reduction, or alleviation of symptoms; reduction in the extent of a condition, disorder, or disease; stabilization (i.e., not worsening) of a condition, disorder, or disease; delay in onset or slowing of progression of a condition, disorder, or disease; improvement in the condition of a condition, disorder, or disease; and remission (whether partial or total), or enhancement or amelioration, whether detectable or undetectable, of a condition, disorder, or disease. Treatment includes eliciting a clinically significant response without undue side effects. Treatment also includes prolonging survival compared to the expected survival if not treated.

[0028] In some embodiments, the compounds and methods disclosed herein can be utilized in conjunction with or on a subject in need of such treatment, which may also be referred to as "in need of." As used herein, the phrase "in need of" means that the subject has been identified as having a need for a particular method or treatment, and the treatment is being administered to the subject for that particular purpose.

[0029] The term "therapeutic agent" or "therapeutic agent" or "pharmaceutical active agent" as used herein means an agent utilized to treat, combat, ameliorate, prevent or improve an undesirable condition or disease in a patient.

[0030] The term "mucocutaneous disease" as used herein refers to any pathological change or condition affecting the skin surface or adjacent mucosal surfaces, including the oral or anogenital mucosa.

[0031] As used herein, the term "composition" refers to a combination or mixture of two or more different ingredients, components, or substances.

[0032] The term "immunostimulant" as used herein refers to an external source that activates the immune system. Immunostimulants can come from multiple sources, such as immunogenic antigens, such as Candida antigens, Trichophyton antigens, and tuberculin, immunogenic microorganisms, such as Corynebacterium parvum, Cutibacterium acnes, and Mycobacterium indicus pranii (formerly Mycobacterium w), immunogenic molecules, such as imiquimod, and immunogenic vaccines, such as human papillomavirus vaccines, measles-mumps-rubella vaccines, mumps vaccines, Bacillus Calmette-Guerin vaccines, and Mycobacterium w vaccines.

[0033] The phrase "therapeutically effective" is intended to modify the amount of active ingredient (ie, a compound or derivative thereof) used to treat a disease or disorder or effect a clinical endpoint.

[0034] A "therapeutically effective amount" or "effective amount" of a compound or composition is a predetermined amount calculated to inhibit, block, or reverse the desired effect, i.e., cell activation, migration, or proliferation. The activity contemplated by the present method includes both medical and / or prophylactic treatment, as appropriate. The specific dose of the compound administered according to the present invention to obtain a therapeutic and / or prophylactic effect will, of course, be determined by the particular circumstances surrounding the case, including, for example, the compound administered, the route of administration, and the condition being treated. The compounds are effective over a wide dosage range. However, it will be understood that the effective amount administered will be determined by the physician in light of the relevant circumstances, including the condition being treated, the choice of compound to be administered, and the chosen route of administration, and thus the above dosage ranges are not intended to limit the scope of the invention in any way. A therapeutically effective amount of a compound of the present invention is typically an amount sufficient to achieve an effective systemic concentration or a local concentration in tissues when administered in a physiologically acceptable excipient composition.

[0035] The term "immune response" as used herein refers to the integrated bodily reaction to an antigen or other immunogenic stimulus in a vertebrate, including the immediate non-specific response of the innate immune system that may be followed by the specific response of the adaptive immune system, which involves the recognition of an antigen or other immunogenic stimulus by specific antibodies or previously sensitized lymphocytes.

[0036] The term "inhibiting" includes administering a compound of the invention to prevent the onset of the symptoms, alleviate the symptoms, relieve the symptoms, slow or reduce the progression of the disease and / or its symptoms, or eliminate the disease, condition, or disorder.

[0037] As used herein, the phrase "essentially free of therapeutically active ingredients" refers to an amount of therapeutically active ingredients that would not elicit a physiological response. "Essentially free of therapeutically active ingredients" can be defined as about 10% or less of a therapeutically active ingredient.

[0038] The term "excipient" as used herein encompasses carriers and diluents, which means materials, compositions or vehicles, such as liquid or solid fillers, diluents, excipients, solvents or encapsulating materials, that are involved in carrying or transporting a pharmaceutical, cosmetic or other agent across a tissue layer, such as the stratum corneum or stratum spinosum.

[0039] The terms "topically" and "topical" as used herein refer to the application of the composition to the surface of the skin, mucosal cells, keratin and tissue. Examples of keratin are nails and hair.

[0040] As used herein, the term "skin" refers to the thin layer of tissue that naturally covers the human and animal body. Skin is made up of the epidermis and the dermis. As used herein, the stratum corneum is the outermost layer of the epidermis and the papillary dermis is the topmost layer of the dermis.

[0041] As used herein, the term "immediate release" refers to a polymer designed to release at least 75% of the therapeutically active ingredient on a time scale of about 0 to about 24 hours.

[0042] As used herein, the term "sustained release" refers to a polymer that does not release more than 75% of the therapeutically active ingredient until more than about 24 hours after application.

[0043] As used herein, the term "biodegradable polymer" refers to a polymer that degrades or dissolves after being introduced into the skin and releasing the therapeutically active ingredient.

[0044] As used herein, the term "sufficient force" refers to the force required to apply the microneedle patch such that the microneedles penetrate the skin to the desired depth.

[0045] As used herein, the term "sensitization" refers to the administration of a therapeutic or stimulating agent to prime the immune system with the intent of obtaining a more robust response with subsequent administration.

[0046] The term "hypersensitivity" as used herein refers to an unwanted reaction produced by the normal immune system, such as allergy or autoimmunity.

[0047] Less than the full scale of the disclosure may be claimed for any reason, by reserving the right to exclude or exclude by proviso any individual member of such group, including any subrange or combination of subranges within such group, which may be claimed according to ranges or similar methods hereby.

[0131] Working Example Although the present invention has been described in some detail with reference to certain preferred embodiments thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description and preferred versions contained within. Various aspects of the present invention will now be described with reference to the following non-limiting examples:

[0132] Example 1: Microneedle patch Two inverted microneedle molds were fabricated using polydimethylsiloxane elastomer (SLYGARD 184, Dow) with an array of 100 microneedles in a square configuration. The dimensions of the microneedles produced in these molds were square pyramids with base width and length of 200 microns, respectively, and lengths of 500 and 800 microns. Microneedles cast in these molds have a configuration similar to that shown in Figure 1. In a preferred embodiment, these microneedles of various lengths are alternated 1:1 in the same patch approximating the skin insertion configuration seen in Figure 2. This alternating length configuration allows for targeted delivery of active ingredients to the epidermis and dermis simultaneously, where the key inflammatory cells of the immune system reside: Langerhans cells in the epidermis and dermal dendritic cells in the dermis.

[0133] Example 2: Microneedle patch Microneedle patches contain cone-shaped needles (Figure 3) to maintain the same volume / dose in both long and short needles, the short needles have a larger radius compared to the long needles, the typical volume of a cone for a particular height (h) and radius (r) is: (h / 3)*n*r2, where: radius of the larger needle-ri; height of the larger needle-h1; height of the smaller needle-h2; radius of the smaller needle-r2 and radius of the smaller needle depend on the height of both needles and radius of the larger needle, to calculate the radius of the smaller needle when other values ​​are defined, the following formula is used: r2=ri*sqrt(h1 / h2). In order to maintain the same volume / dose for both long and short needles, in microneedle patches where the microneedle patch contains pyramidal shaped needles, the short needles have a larger radius compared to the long needles, the typical volume of a square based pyramid for a given base length (L) and height (H) is: (l / 3)*L2*H, where the base length of the larger needle - Ll, the height of the larger needle - Hl, the height of the smaller needle - H2, the base length of the smaller needle - L2, the base length of the smaller needle depends on the height of both needles and the base length of the larger needle, to calculate the radius of the smaller needle when other values ​​are defined, the following formula is used: L2=Ll*sqrt(Hl / H2).

[0134] Example 3: Removal of glycerin from Candida antigens Many of the commercially available immunostimulatory compounds are suspended in solutions containing glycerin. For example, HS Allergy's Candida antigen (both 1:10 w / v and 1:1000 w / v concentrations) contains 50% glycerin by weight. When a glycerin-containing solution is mixed with a microneedle polymer, precipitation and / or lack of solidification occurs. For example, when glycerin-containing Candida antigen is mixed with polylactic-co-glycolic acid (PLGA) 5050 (molecular weight 7-17k, or simply 7-17k), precipitation was observed. For example, when glycerin-containing Candida antigen is mixed with carboxymethylcellulose (CMC), lack of solidification was observed. Therefore, it is necessary to remove glycerin from the immunostimulatory compound solution before incorporation into the microneedle polymer.

[0135] 4 g of a 1:10 w / v Candida antigen solution (HS Allergy) was dialyzed to remove all traces of glycerin from the solution. After dialysis, 18 g of sample remained (4.5-fold dilution). Ultraviolet-visible spectroscopy (UV-Vis) was used to establish the absorbance characteristics of the undialyzed Candida antigen. Using this UV-Vis method, a 36-fold dilution of the original active ingredient solution and a 2-fold dilution of the dialyzed sample showed similar absorbance, indicating that the dialyzed sample without glycerin was approximately 1 / 20th of the original concentration.

[0136] Example 4: Lyophilized Candida antigen Certain microneedle polymers, such as PLGA5050 7-17k, are ideal for incorporating the active ingredient in lyophilized form prior to microneedle molding. The process of lyophilization removes water and results in a powder. Glycerin causes similar problems with lyophilization as outlined in Example 2. When lyophilization was attempted with a 1:10 w / v Candida antigen solution (HS Allergy) containing glycerin, a viscous liquid was obtained rather than a solid. The formation of a solid indicates successful lyophilization. When the glycerin was removed using the dialysis method outlined in Example 3, lyophilization of the dialyzed Candida antigen produced solid white flakes indicating all water had been removed.

[0137] Example 5: Carboxymethylcellulose microneedle array The mold of Example 1 was filled with a 2% solution of CMC and allowed to dry before demolding. After demolding, the resulting microneedle arrays were analyzed by scanning electron microscopy. These microneedle arrays showed that microneedles with the dimensions described in Example 1 were successfully produced (Figures 4 and 5).

[0138] Example 6: Skin permeability of microneedle arrays A blue tissue labeling dye was added to the CMC solution, and microneedle arrays were prepared in the same manner as in Example 5. After drying, the resulting microneedle arrays were demolded and inserted into pig skin to evaluate their penetration and ability to deliver active ingredients. The needles were left on the skin for less than 10 minutes after insertion. The pig skin was then washed with copious amounts of water. After washing, the blue dye was visibly evident at the insertion sites of both the 500 micron and 800 micron microneedle arrays (Figure 6), indicating successful skin penetration and dissolution. Cross sections of pig skin demonstrated effective dye delivery to the epidermis and superficial dermis (Figure 7).

[0139] Example 7: Candida antigen microneedle patch A 1 g dialyzed sample of the Candida antigen of Example 3 (equivalent to approximately 50 mg of the original undialysed material) was used to make an immediate release polymer formulation and mixed with approximately 17 g of aqueous CMC. This mixture was then poured into the mold of Example 1 to make a microneedle array. After drying and demolding, these microneedle arrays, containing approximately 75% payload of 1:10 w / v Candida antigen solution, were analyzed by scanning electron microscopy. These microneedle arrays were shown to successfully produce active ingredient microneedles of the dimensions described in Example 1 (Figures 8 and 9). If these needles were alternating in the same microneedle array, the resulting microneedle array when inserted into the skin would approximate the appearance of Figure 10.

[0140] Example 8: Immediate release and sustained release microneedles The compositions for microneedle and sustained release patches also have an immediate release component as a separate layer. To extend the release of the active ingredient, the freeze-dried Candida antigen of Example 4 was mixed with PLGA5050 7-17k. The resulting mixture was then poured into the mold of Example 1 to produce microneedle arrays. After drying and demolding, these microneedle arrays were analyzed for in vitro release using the UV-Vis assay of Example 3. The microneedle arrays were placed in deionized water at 32 degrees Celsius. The Candida antigen was shown to be consistently released from the microneedles over a 24-hour period (although the total release was 75% or less), and complete release is expected to be consistent over a 2-day period based on the release kinetics (Figure 11).

[0141] An additional layer of the active ingredient and polymer mixture from Example 7 could be poured onto the microneedle array of this example before demolding to create a sustained release microneedle tip and a fast dissolving water-soluble microneedle base (Figure 12). Upon insertion into the skin, the water-soluble polymer layer quickly dissolves, releasing the sustained release polymer layer into the skin. The adhesive backing can then be removed within minutes, while release of the active ingredient was possible for several days, as shown by the release kinetics in Figure 11.

[0142] Example 9: Use of microneedle arrays for pre-treatment testing Considering the immunostimulatory properties of the microneedle array described in the previous examples, initially treating a patient with a sustained release version of the active ingredient without prior testing with an immediate release formulation may lead to severe or life-threatening reactions if the patient is allergic to the active ingredient delivered continuously over several days. Pre-testing with an immediate release patch as a first test in all patients is necessary not only to prevent complications but also to sensitize the patient's immune system to the immunostimulatory compound. Thus, the patient can be treated with either a treatment regimen consisting of successive applications of the microneedle array of FIG. 10 (the regimen shown in FIG. 13) or a treatment regimen consisting of an initial application of the microneedle array of FIG. 10 followed by successive applications of the microneedle array of FIG. 12 (the regimen in FIG. 14).

[0143] Example 10: Immediate Release Microneedles As shown in Figure 10, such microneedle patches and compositions are for immediate release patches used for pre-testing of patients for allergy / hypersensitivity testing, sensitizing the patient to the therapeutic active ingredient before transitioning to a sustained release patch for therapeutic application against skin diseases targeted by local immune stimulation induced by the active therapeutic molecule so tested. The immediate release patch is typically applied for 0-24 hours of active ingredient delivery and testing.

[0144] Example 11: Glycerin Removal To remove glycerin from the glycerin-containing immunostimulatory compound solution, the solution containing glycerin was added to a dialysis device with a built-in dialysis membrane (Repligen (Waltham, Massachusetts, USA) Float-A-Lyzer G2 dialysis device, Biotech Cellulose Ester membrane, 10 mL, 0.1-0.5 kD). The dialysis device was immersed in deionized water and gently stirred at ambient temperature for 2-4 hours. The deionized water was then replaced with the same volume of fresh deionized water, and the device was immersed at ambient temperature for another 12-24 hours with gentle stirring. During this process, glycerin diffused from the dialysis device into the surrounding deionized water. After the entire process of immersion in deionized water described above was completed, the dialysis device was removed from the deionized water, and the sample contained a glycerin-free solution of the immunostimulatory compound. This treated solution can then be directly incorporated with a water-soluble polymer, lyophilized and incorporated with a water-soluble polymer, or resuspended and incorporated with a water-soluble polymer.

[0145] Example 12: Perilesional application of microneedle arrays Injection of a therapeutic agent provides perilesional delivery of the therapeutic active ingredient to the skin adjacent to the skin lesion (Figure 15). Intralesional delivery of a therapeutic agent via a microneedle array can be limited by the three-dimensional shape of the skin lesion, resulting in delivery of the therapeutic active ingredient to different skin areas based on the shape and size of the lesion (Figure 16). Perilesional delivery of a microneedle array allows for consistent and precise delivery of a therapeutic agent (Figure 17). Microneedle patches can also be applied such that some of the microneedles deliver the therapeutic agent perilesional and the remaining microneedles deliver the therapeutic agent intralesional (Figure 18). Alternatively, two or more microneedle patches may be applied to the skin, where one microneedle patch is applied perilesional and another microneedle patch is applied intralesional (Figure 19).

[0146] Example 13: Immune Stimulation A dissolvable microneedle patch containing an immune stimulating compound was applied to the skin on the dorsum of the hand. The patch was left in place for 5 minutes to allow the dissolvable microneedles to dissolve within the skin. The patch was removed and discarded after 5 minutes. Results of the inflammatory response 48 hours after patch application (Figure 20). A visible erythematous response was contained within the site of the microneedle array (Figure 21, Area A). Visible inflammation, represented by depigmented edema outside the site of skin contact with the microneedle array, was seen in the periphery surrounding the site where the microneedle patch was applied (Figure 21, Area B). Figure 22 shows the area of ​​inflammation outside the area of ​​skin contact with the microneedle array as shaded. This perilesional area is the area where the skin condition of interest may be treated by application of a perilesional patch and is represented by the shaded area in Figure 22. This area represents the distance from the site of microneedle patch application. The maximum distance in this case is approximately 1 cm. The distance of perilesional efficacy may be even greater if the relative dose of immune stimulating compound antigenic extract is higher.
