[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 350,982, filed on June 10, 2022, which is incorporated by reference in its entirety.
[0003] Reference sequence list
[0004] This application is submitted in electronic format together with a sequence listing. The sequence listing is provided as a file titled PPORT.008WO_ST_26.xml, which was created on June 6, 2023 and is approximately 7kb in size. The information in the electronic format of the sequence listing is incorporated herein by reference in its entirety. Background of the Invention
[0006] field
[0007] The present application relates to compositions, devices and methods for transdermal drug delivery, and in particular to peptide compositions and methods of administering the peptides to a subject via a transdermal microporation device.
[0008] describe
[0009] Alzheimer's disease (AD) is the most common senile dementia disease. The increase in AD patients is a serious problem in the world. Familial gene mutations that increase the risk of developing AD have been found, but most cases are considered to be due to cognitive decline caused by age-related changes in the brain. Therefore, although aging is the biggest risk factor for developing AD, a common characteristic change in AD patients is the accumulation of β-amyloid protein (Aβ) in the brain. Aβ increases with age, forming aggregates of Aβ oligomers in the brain and producing cytotoxicity. Since it has been reported that Aβ oligomers cause cognitive decline, Aβ is considered to be a strong cause of AD onset.
[0010] The neurospecific membrane protein Alcadeinβ is metabolized to produce p3-Alcβ by a pathway similar to Aβ. Unlike Aβ, which accumulates exponentially in the brain as it ages, p3-Alcβ does not accumulate in the brain, decreases from cerebrospinal fluid (CSF) as it ages, and p3-Alcβ in the CSF of AD patients is further significantly reduced compared to age-matched non-demented subjects, so it is considered to be involved in the onset of AD. In addition, unlike Aβ, p3-Alcβ does not have aggregates, and p3-Alcβ alleviates neurotoxicity caused by Aβo and improves cognitive function by peripheral administration in acute cognitive function model mice induced by Aβ oligomers. It has been clarified that p3-Alcβ shows a reduction and improvement effect. Therefore, the increase of toxic Aβ oligomers and the reduction of p3-Alcβ with an inhibitory effect are considered to be involved in the onset and progression of AD. Since the action of p3-Alcβ is accomplished through its partial peptide p3-Alcβ9-19, the onset and progression of AD associated with the reduction of endogenous molecule p3-Alcβ can be prevented by allowing p3-Alcβ9-19 to reach the brain.
[0011] Various peptide compositions and treatments for AD have been proposed. However, peptide drugs are generally unstable in vivo and difficult to deliver to the brain. Therefore, there is still a long-standing need for improved peptides, formulations, compositions, devices and methods for delivering peptides to cross the blood-brain barrier.

[0038] definition
[0039] 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. Unless otherwise indicated, all patents, applications, published applications, and other publications cited herein are incorporated herein by reference in their entirety. If multiple definitions exist for a term herein, those in this section shall prevail unless otherwise indicated.
[0040] As used throughout, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a filament" may include two or more such filaments unless the context dictates otherwise.
[0041] Ranges may be expressed herein as from "about" one particular value, and / or to "about" another particular value. When such ranges are expressed, another aspect includes from a particular value and / or to another particular value. Similarly, when values are expressed as approximations by using the antecedent "about," it will be understood that the particular values form another aspect. It will be further understood that the endpoints of each range are important both relative to the other endpoint and independently of the other endpoint.
[0042] As used herein, the terms "optional" or "optionally" mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
[0043] As used herein, "stratum corneum" refers to the outermost layer of the skin, consisting of about 15 to about 20 layers of cells in various stages of dryness. The stratum corneum provides a barrier to prevent water loss from the interior of the body to the external environment and to prevent attacks from the external environment to the interior of the body.
[0044] As used herein, "tissue" refers to an aggregate of cells of a particular type together with their intercellular substances that form a structural material. In the case of drug delivery to or through such tissue, a transdermal delivery method (e.g., a perforation device and / or a patch) can access at least one surface of the tissue. The tissue is the skin for various perforation delivery methods described herein. Other tissues suitable for the present disclosure include mucosal tissues and soft organs.
[0045] As used herein, the term "interstitial fluid" is the clear fluid that occupies the spaces between cells in the body.
[0046] As used herein, the term "biological fluid" is defined as a fluid derived from a biological organism, including serum or whole blood, and interstitial fluid.
[0047] As used herein, "tissue membrane" can be any one or more epidermal layers of an object. For example, in one aspect, a tissue membrane is a skin layer including the outermost layer (i.e., stratum corneum) of the skin. In an optional aspect, the skin layer can include one or more backing layers of the epidermis, generally identified as the stratum granulosum, the stratum malpighii, and the stratum germinativum. It will be understood by those of ordinary skill in the art that the transport or absorption of the permeate through the backing layer of the epidermis is substantially free of or free of resistance. Therefore, in one aspect, at least one channel formed in the skin layer of an object is a channel in the stratum corneum of the object. In addition, as used herein, "stratum corneum" refers to the outermost layer of the skin, generally comprising about 15 to about 20 layers of cells in various stages of drying. The stratum corneum provides a barrier to prevent water from being lost from the inside of the body to the external environment and to prevent attacks from the external environment to the inside of the body. In addition, as used herein, "tissue membrane" can refer to an aggregate of cells of a specific type forming a structural material together with their intercellular substances. In various embodiments, one or more perforating devices and / or permeation compositions described herein can approach at least one surface of a tissue membrane. As described above, the tissue membrane used for various perforation delivery methods is the skin. Other tissues suitable for use with such devices and compositions include mucosal tissues and soft organs.
[0048] As used herein, the term "subcutaneous fluid" may include, but is not limited to, water, plasma, blood, one or more proteins, interstitial fluid, and any combination thereof. In one aspect, the subcutaneous fluid according to the present specification is a moisture source comprising water.
[0049] As used herein, "perforation", "microperforation" or any such similar terms means the formation of small holes or cracks (hereinafter also referred to as "micropores") in or through a tissue or biological membrane, such as the skin or mucous membrane, or the outer layer of an organism, to reduce the barrier properties of the biological membrane for the passage of at least one permeate from one side of the biological membrane to the other side for a selected purpose. Preferably, the diameter of the hole or "micropore" so formed is about 1-1000 microns and extends into the biological membrane sufficient to disrupt the barrier properties of the stratum corneum without adversely affecting the underlying tissue. It should be understood that for simplicity, the term "micropore" is used in the singular, but the microporous device described herein can form a plurality of artificial openings. For a selected purpose, or for certain medical or surgical procedures, perforation can reduce the barrier properties of the biological membrane to enter the body. For the purposes of this application, "perforation" and "microperforation" are used interchangeably and mean the same thing.
[0050] A "microporator" or "porator" is a component for a microporation device capable of microporation. Examples of microporators or perforators include, but are not limited to, a filament capable of conductively transferring thermal energy via direct contact with a biological membrane to cause a portion of the membrane to burn deep enough to form micropores, an optically heated local dye / absorbent layer, an electromechanical actuator, a microlancet, an array of microneedles or lancets, an acoustic energy cauterizer, a laser cauterization system, a high-pressure fluid jet puncturer, and the like. As used herein, "microporator" and "porator" are used interchangeably.
[0051] As used herein, "permeation" means the controlled removal of cells caused by the heat and kinetic energy released when the pyrotechnic element explodes, which causes the cells of the biofilm and possibly some neighboring cells to be "blown away" from the scene. As used herein, "fusible" and "fuse" refer to an element that can remove itself from an electrical circuit when a sufficient amount of energy or heat is applied to it. That is, when a resistive electrically activated perforating element is designed as a fusible element, this means that upon activation, during or after the formation of micropores in the biofilm, the element breaks, thereby preventing current from flowing through the element.
[0052] As used herein, "penetration enhancement" or "permeation enhancement" means an increase in the permeability of a biological membrane and / or tissue to a drug, biologically active composition, or other chemical molecule, compound, particle, or substance (also referred to as a "permeant") so as to increase the rate at which the drug, biologically active composition, or other chemical molecule, compound, or particle penetrates the biological membrane and / or tissue.
[0053] As used herein, "enhancer", "chemical enhancer", "penetration enhancer", "permeation enhancer", etc. include all enhancers that increase the flux of permeates, analytes or other molecules across biological membranes and are limited only by functionality. In other words, it is intended to include all cell envelope disordering compounds and solvents as well as any other chemical enhancers. In addition, all active force enhancement techniques are included, such as the application of acoustic energy, mechanical suction, pressure or local deformation of tissue, iontophoresis or electroporation. One or more enhancer technologies can be combined sequentially or simultaneously. For example, a chemical enhancer can be applied first to penetrate the capillary wall, and then iontophoresis or an acoustic energy field can be applied to actively drive the permeate into those tissues surrounding and including the capillary bed.
[0054] As used herein, "transdermal" or "percutaneous" means the passage of a permeant into and through a biological membrane to achieve therapeutically effective blood concentrations or local tissue levels of the permeant, or the passage of molecules or fluids ("analytes") present in the body out of a biological membrane so that the analyte molecules can be collected outside the body.
[0055] As used herein, the terms "permeant," "drug," "permeant composition," or "pharmacologically active agent," or any other similar term, are used interchangeably to refer to any chemical or biological material or compound suitable for transdermal administration by methods previously known in the art and / or by methods taught in this specification that induces a desired biological or pharmacological effect, which may include, but is not limited to (1) having a prophylactic effect on an organism and preventing undesirable biological effects, such as infection, (2) alleviating a condition caused by a disease, such as reducing pain or inflammation, and / or (3) alleviating, reducing, or completely eliminating a disease from an organism. The effect may be local, such as providing a local anesthetic effect, or may be systemic. Such substances include a wide variety of compounds that are typically delivered into the body, including through body surfaces and membranes, including the skin. In general, by way of example and without limitation, such substances may include any biologically active agent, such as a drug, chemical material, or biological material, that induces a desired biological or pharmacological effect. To this end, in one aspect, the permeant may be a small molecule agent. In another aspect, the permeant may be a macromolecular agent.
[0056] In various embodiments, systems, devices, and methods that can be used and / or adapted for use with the compositions and methods described herein are described in one or more of U.S. Pat. Nos. 6,022,316, 6,142,939, 6,173,202, 6,183,434, 6,508,785, 6,527,716, 6,692,456, 6,730,028, 7,141,034, 7,392,080, 7,758,561, 8,016,811, 8,116,860, and / or 9,498,609, all of which are hereby incorporated by reference in their entireties and specifically for the purpose of describing such systems and methods. In various embodiments, the compositions and methods described herein may be used in combination with the compositions and methods described herein. Commercially available systems and devices can be used or adapted to deliver the compositions described herein.
[0057] As used herein, an "effective" amount of a pharmacologically active agent means a sufficient amount of the compound to provide the desired local or systemic effect and performance at a reasonable benefit / risk ratio in any medical treatment. An "effective" amount of a permeate or chemical enhancer as used herein means an amount selected to provide the desired increase in biomembrane permeability, the desired depth of penetration, the rate of administration, and the amount of drug delivery.
[0058] As used herein, "animal" or "organism" refers to humans and other living organisms, including plants, to which the present disclosure may be applied.
[0059] As used herein, "analyte" means any chemical or biological material or compound suitable for passing through a biological membrane by the techniques taught in the present disclosure or by techniques previously known in the art, and an individual may wish to know the concentration or activity of the chemical or biological material or compound in vivo. Glucose is a specific example of an analyte because it is a sugar suitable for passing through the skin, and an individual (e.g., an individual with diabetes) may wish to know their blood sugar level. Other examples of analytes include, but are not limited to, compounds such as sodium, potassium, bilirubin, urea, ammonia, calcium, lead, iron, lithium, salicylates, etc.
[0060] As used herein, "transdermal flux rate" is the rate of passage of any analyte through the skin of an individual, human or animal, or the rate of passage of any permeant, drug, pharmacologically active agent, dye or pigment into or through the skin of an organism.
[0061] As used herein, "non-invasive" means not requiring the passage of a needle, catheter, or other invasive medical device into a part of the body.
[0062] As used herein, "minimally invasive" refers to the use of mechanical, hydraulic, or electrical devices to penetrate the stratum corneum to create small holes or micropores without causing substantial damage to the underlying tissue.
[0063] As used herein, "pharmaceutically acceptable carrier" refers to a carrier in which a substance for delivery (e.g., a pharmaceutically acceptable drug) can be provided. Pharmaceutically acceptable carriers are described in the art, for example, in "Remington: The Science and Practice of Pharmacy," Mack Publishing Company, Pennsylvania, 1995, the disclosure of which is incorporated herein by reference. Carriers can include, for example, water and other aqueous solutions, sugars, polysaccharides, buffers, excipients, and biodegradable polymers (e.g., polyesters, polyanhydrides, polyamino acids, liposomes, and mixtures thereof).
[0064] As used herein, "reservoir" refers to a designated area or chamber in a device that is designed to hold a permeate for delivery to an organism through an artificial opening in a biofilm, or can be designed to receive a biological fluid sample extracted from an organism through an artificial opening in a biofilm. The reservoir can also hold excipient compounds that enhance the effect of a biologically active permeate contained alone. In addition, the reservoir can hold a reactive enzyme or reagent that is designed to allow measurement or detection of a selected analyte in the extracted biological fluid, or can be treated with the reactive enzyme or reagent. The reservoir can include an open volume space, a gel, a planar space (which has been coated or treated with a selected compound for subsequent release or reaction), or a matrix or a permeable solid structure (e.g., a pellet, a tablet, a powder, a dry solid or a porous polymer).
[0065] As used herein, "p3-Alcβ" will be produced as a metabolite of the membrane protein Alcadeinβ (Alcβ). Alcβ is metabolized by a pathway similar to Aβ to produce p3-Alcβ. Unlike Aβ accumulated in the brain, p3-Alcβ is more significantly reduced in Alzheimer's patients. The effect of p3-Alcβ is achieved through its partial peptides, such as p3-Alcβ1-40, p3-Alcβ1-37, p3-Alcβ9-19, p3-Alcβ1-19, p3-Alcβ11-19 or its derivatives.

In some embodiments, the patch of the present disclosure can deliver the non-aggregated peptide transdermally to a subject through one or more micropores formed by a transdermal delivery system as described herein. In some embodiments, the method may include punching holes in the outermost stratum corneum and epidermis, and then applying a patch thereon, so that the non-aggregated peptide in the patch passes through the epidermis, diffuses into the capillary dermis, and enters the systemic circulation. Non-aggregated peptides absorbed from the skin can avoid first-pass metabolism in the liver and be effectively delivered to the brain. Therefore, embodiments of the patch of the present disclosure can provide a means of drug administration to replace injection, and the patch can be appropriately used for immediate release applications or sustained release of non-aggregated peptides, with higher bioavailability compared to oral, nasal or passive transdermal administration.
[0102] In some embodiments, the patch of the present disclosure can also be used in a method for delivering non-aggregated peptides through a target biological membrane, wherein the method includes a step for forming one or more micropores in the biological membrane and a step for placing the patch in physical contact with the one or more micropores so that at least a portion of the drug can be dissolved in the biological moisture received from the target through the one or more micropores.

[0112] In some embodiments, before obtaining a high level of non-aggregated peptides, the object receives enough non-aggregated peptides from multiple dosages. It is easy and immediately conceivable to have a scheme in which the first patch is applied to the object, and the object receives one or more subsequent patches. Such schemes can be continued so that the object receives the third patch after receiving the second patch. In some embodiments, the object can receive 1,2,3,4,5,6,7,8,9,10 or more patches during treatment. One or more additional patches as described herein can be applied before the first patch dosage or before one or more subsequent patch dosages. In some embodiments, the object receives dosage during the time course of the remainder of his or her life and / or in the time of many years (for example, more than or equal to 1 year, 5 years, 10 years, 15 years, 20 years, 30 years or including and / or spanning the scope of the above values).
[0113] In some cases, a period of time passes between applying one or more patches to a subject. In some embodiments, the time period between applying one or more patches is equal to or at least about: twice a day, 1 day, 1 week, 2 weeks, 3 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, 1 year, or a range including and / or spanning the above values. In some embodiments, one or more additional therapeutic agents are administered to a subject during the time period between applying the composition to the subject.
[0114] Before receiving the first treatment using the patch described herein, it is not always necessary to identify the subject who needs to receive the patch as disclosed herein to improve the health of the subject. For example, before showing any current signs or symptoms of Alzheimer's disease (normal cognition in the preclinical stage) or mild cognitive problems of Alzheimer's disease (mild MCI stage), it can be predetermined that the subject will develop Alzheimer's disease in the future. Alternatively, if the subject is at risk of Alzheimer's disease or (for example, once the patient reaches an age equal to or greater than 50, 60, 70, etc.) is not at risk of Alzheimer's disease, he or she can be treated prophylactically. Therefore, in some embodiments, after the subject receives an early diagnosis, the patch is applied to the subject. In some embodiments, not every subject is a candidate for such administration, and it may be necessary to identify the subject for treatment. It should be understood that the selection of the patient depends on many factors within the skill range of an ordinary skilled physician. Therefore, some embodiments disclosed herein also include identifying the subject as a subject that will benefit from the administration of an effective amount of at least one non-aggregating peptide or a composition comprising the non-aggregating peptide to increase lifespan, increase survival time, increase natural lifespan or improve immunity. According to the age of the subject, the current medical condition, the current medical treatment, the prescribed medical treatment or in some embodiments, the subject diagnosed with Alzheimer's disease, the subject can be identified based on the subject's specific physiological factors. In some embodiments, the treatment of Alzheimer's disease includes preventing, reducing and / or slowing the accumulation of beta-amyloid protein, amyloid plaques and / or tau protein tangles. Beta-amyloid protein is the remaining fragment of a larger protein. When these fragments gather together, they appear to have a toxic effect on neurons and destroy intercellular communication. These aggregates form larger deposits called amyloid plaques, which also include other cell fragments. Tau protein plays a role in the internal support and transport system of neurons to carry nutrients and other essential substances. In Alzheimer's disease, tau protein changes shape and organizes itself into a structure called neurofibrillary tangles. Tangles destroy the transport system and are toxic to cells.

[0125] System / Equipment
[0126] The basic configuration of microperforated drug delivery system is known to those skilled in the art, so further detailed description is not required herein.For example, in U.S. Patent No. 8,116,860, a transdermal permeation delivery system is described, which is incorporated herein by reference and particularly for the purpose of describing the various features of such microperforated drug delivery system.As described in the patent, the microperforated drug delivery system of U.S. Patent No. 8,116,860 (referring to using reference number "10" therein) includes the basic features containing filament array (referring to using reference number "70" therein) and one or more transdermal patches (referring to using reference number "100" therein), the filament array is configured to produce one or more channels or micropores in the skin of the patient, and the transdermal patch includes at least one pharmaceutical preparation.Other similar microperforated drug delivery systems including such basic features are known to those skilled in the art.Various microperforated drug delivery systems with such basic features are known to those skilled in the art, and can be used or transformed by those skilled in the art under the guidance of the teachings provided herein.
[0127] In some embodiments, a microporation device can be defined by the total area of channels (e.g., micropores) created in the skin by one or more filaments and the total energy delivered to the one or more filaments to create the channels. In some embodiments, a microporation device creates channels such that the total area of the channels in the skin is approximately 0.25 cm per square centimeter (cm) of skin. 2 Up to 4.0cm 2 In some embodiments, the channels in the skin may preferably comprise approximately 0.5% to 12.5% of the skin area for each square centimeter of skin exposed to the microporation device. In some embodiments, the channels in the skin may preferably comprise approximately 1.25% to 10% of the skin area for each square centimeter of skin exposed to the microporation device.
[0128] In some embodiments, the energy delivered to one or more filaments to create a channel may be in the range of 0.0067 μJ / μm 3 -0.0400μJ / μm 3 . The energy delivered to one or more filaments can be delivered in pulses of 2 to 12 milliseconds (ms) to provide enough energy to produce a continuous channel for delivery. The characteristics of the channel for efficiently and safely delivering drugs through the skin (e.g., from a patch described herein) can vary between in vitro and in vivo embodiments. For example, in some embodiments, when 2mJ / filament to 12mJ / filament energy is applied to one or more filaments in pulses of 2ms to 16ms, one or more filaments produce a channel. In some embodiments, the energy applied to one or more filaments to produce a channel is 2mJ / filament to 8mJ / filament, 2mJ / filament to 6mJ / filament, or 2mJ / filament to 4mJ / filament. In some embodiments, the duration of the pulse is 2ms to 12ms. In such embodiments, one or more filaments may comprise stainless steel or be substantially formed of stainless steel, and for 2mJ / filament-12mJ / filament, have a volume (V) of 300,000μm 3 (0.0067μJ / μm 3 -0.0400mJ / μm 3 ).
[0129] In some embodiments, one or more filaments arranged in a filament array can create 25 channels / cm in a biological membrane (e.g., skin) to which the one or more filaments are exposed. 2 Up to 500 channels / cm 2 In some embodiments, one or more filaments arranged in a filament array can create 50 channels / cm on the skin exposed by the one or more filaments. 2 Up to 400 channels / cm 2 .
[0130] In some embodiments, the cumulative (or total) depth of all channels formed by one or more filaments is about 2500 μm to 30000 μm per square centimeter of skin exposed to the one or more filaments. In some embodiments, the cumulative or total volume of all channels formed by one or more filaments is about 0.05 mm per square centimeter of skin. 3 Up to 0.35mm 3 .
[0131] In some embodiments, the patches described herein, used with channels created by a microporation device, may have one or more features that enhance optimal drug release and diffusion of non-aggregated peptides into the body.
[0132] In some embodiments, improvements to microporation devices and patches as described herein enable microporation drug delivery systems to effectively and safely provide delivery of non-aggregated peptides in a manner that provides improved bioavailability and / or transferability of non-aggregated peptides from the blood of a subject to the cerebrospinal fluid. Embodiments of the microporation drug delivery systems described herein can provide improved patient compliance and enhanced drug delivery capabilities. Embodiments of the microporation drug delivery systems can also provide a reduced risk of adverse reactions caused by uncontrolled delivery and reduce the development period and cost of drugs for patients. Embodiments of the microporation drug delivery systems also enable patients to painlessly and needle-free self-administer the corresponding drug at a location of the patient's choice, which results in improved compliance and reduced costs (fewer visits to health care professionals). Embodiments of the microporation drug delivery systems as described herein can be used for patients with a wide range of skin types, conditions, etc., where the variation in individual drug delivery results is small.
[0133] Example
[0134] Various embodiments and alternatives are disclosed in further detail in the following examples, which are not in any way intended to limit the scope of the claims.
[0135] Alzheimer's disease. Alzheimer's disease is a chronic disease that develops with aging. Therefore, due to the nature of Alzheimer's disease, drugs may require long-term daily administration. Therefore, IV administration is not desirable because it requires hospitalization or daily visits. Subcutaneous administration can be developed as a self-administering device, such as a pen injector. However, it is believed that it will not be effective for most patients in the long term due to pain and handling issues for the patient. In addition, patients sometimes suffer from needle phobia. Therefore, it is believed that percutaneous microporation will have good compliance and will serve as a long-term home therapy. In this study, a percutaneous microporation device was studied for the non-aggregating peptide p3-Alcβ to enhance the delivery of p3-Alcβ to the brain compared to other modes of administration and to determine the effectiveness of various modes of administration.
[0136] p3-Alcβ. Figure 1 The amino acid sequences of p3-Alcβ1-40, p3-Alcβ1-37, p3-Alcβ9-19, p3-Alcβ1-19, and p3-Alcβ11-19, which are partial peptides of Alcadeinβ, are described. The human p3-Alcβ37 peptide and its partial peptide p3-Alcβ9-19 were synthesized and purified to a purity of greater than 95%, wherein the human p3-Alcβ37 peptide includes the sequence from Val813 to Thr849 of Alcβ described in Hata et al "Alcadein cleavages by amyloidβ-precursor protein (APP)α-andγ-secretasegenerates small peptides, p3-Alcs, indicating Alzheimer'sdisease-relatedγ-secretase dysfunction" J.Biol.Chem.
[2009] 284, 36024-36033; their expected molecular weights were confirmed by mass spectrometry performed at the Peptide Research Institute (Osaka, Japan).
[0137] Animal studies in rats. Oral, nasal, injection and percutaneous microporation containing p3-Alcβ9-19 were tested to determine pharmacokinetics in vivo, such as PK characteristics, bioavailability and drug recovery. In vivo PK studies were performed in CD rats (Charles River Laboratories) according to an IACUC-approved animal protocol. Each dose formulation was prepared before the experiment. Patches were made according to the dry patch manufacturing procedure. Animals for transdermal application were shaved 1 day before the date of administration. Transdermal microporation was implemented using an applicator and a perforator. Then, the patch was placed to cover the perforated area for 1 day or a specified duration. After the last blood draw, the patch was collected and the application site was wiped with paper or cotton to recover the remaining drug on the skin. Blood samples were collected from the tail vein and transferred to K2-EDTA tubes at the specified sampling time. The samples were centrifuged at 4°C and plasma samples were obtained. All samples were stored in a -80°C refrigerator until bioassay.
[0138] Sample preparation for LCMSMS analysis of p3-Alcβ9-19. Keep the plasma samples at room temperature for 30 minutes. Transfer the plasma (50 μL) to a 2 mL Eppendorf tube (Protein LoBind), then add 50 μL of acetonitrile / DMSO (4:1, v / v), and vortex the tube for a few seconds. Centrifuge the sample at 3700 rpm, 4°C for 15 minutes. Place 150 μL of mobile phase A (0.1% formic acid in water) in a new tube, then transfer 50 μL of the supernatant to the tube, and vortex the sample for 5 minutes. Remove the supernatant and filter the solution through a 0.20 μm PTFE membrane into an automatic sampling vial (LCMSMS).

[0145] Animal studies in mice. The transport of p3-Alcβ9-19 to blood and cerebrospinal fluid (CSF) was tested in wild-type mice (4 months). Hair was removed before the experiment. Percutaneous microporation was applied, and then a patch containing p3-Alcβ9-19 was applied to the perforated area. Mice were anesthetized with 1% isoflurane, CSF was collected from the cisterna magna of mice, blood was collected from the inferior vena cava of mice, and the CSF and blood were collected into tubes containing EDTA and heparin, as described in Liu et al, "A technique for serial collection of cerebrospinal fluid from the cisterna magna in mouse." J.Vis.Exp.21 (2008).
[0146] sELISA method development for p3-Alcβ9-19 analysis. Developed a sELISA method for measuring p3-Alcβ9-19 in cerebrospinal fluid (CSF). Polyclonal rabbit antibodies to p3-Alcβ9-19 (C+HRGHQPPPEMA) containing an amino-terminal Cys residue were stimulated and conjugated to bovine thyroglobulin. IgG was purified with an antigen-coupled resin and conjugated to biotin. Horseradish peroxidase-conjugated streptavidin was from Amersham / GE Healthcare (Cat#RPN1051, Little Chalfont, UK), and tetramethylbenzidine (TMB) microporous peroxidase substrate system was from SeraCare Life Sciences Inc. (Cat#5120-0075, Milford, MA, USA). Mice were anesthetized by using 1% isoflurane, and CSF was collected from the cisterna magna of mice as described above, and then the mice were killed.
[0147] To quantify p3-Alc[beta]9-19 in mouse CSF and plasma, samples were diluted with buffer A (PBS containing 1% bovine serum albumin and 0.05% Tween-20). Using polyclonal antibodies, the developed sELISA system quantified p3-Alcβ9-19 in the range of 25-200 pg / ml, with sensitivity equivalent to that of p3-Alcα35-specific (as described in Omori et al., “Increased levels of plasma p3-Alcα35, a major fragment of Alcadeiνα byγ-secretase cleavage, in Alzheimer's disease” J. Alzheimers. Dis. (2014) 39, 861-870), p3-Alcβ37- and p3-Alcβ40-specific sELISA systems (as described in Hata et al. “Decrease in p3-Alcβ37and p3-Alcβ40, products of Alcadeinβ generated byγ-secretase cleavages, in aged monkeys and patients with Alzheimer's disease” Alzheimers Dement TRCI (2019) 5, 740-750). In this p3-Alcβ9-19 sELISA system, a 1:10,000-fold diluted antiserum was used as the capture antibody, and affinity-purified antiserum with antigen-coupled resin and biotin-labeled IgG was used for detection antibody. This sELISA system does not react with p3-Alcβ37. The added 1,000pg / ml p3-Alcβ37 does not compete with antibodies that bind to 0-200pg / ml p3-Alcβ9-19. The sELISA method is used to measure p3-Alcβ9-19 in body fluids, even in the presence of endogenous p3-Alcβ in mice.
[0148] sELISA method for p3-Alcβ9-19 analysis. Rabbit antiserum immunized with p3-Alcβ9-19 as an antigen was coated on a 96-well plate as a capture antibody and incubated at 4°C overnight. On the next day, non-bound antibodies were removed with a wash buffer (0.05% Tween-20 in PBS). Plasma was diluted 200 times and cerebrospinal fluid was diluted 20 times with EIA buffer (1% BSA, 0.05% Tween-20), respectively. The sample solution was added to a 96-well plate and incubated at 4°C overnight. On the next day, after washing with a wash buffer, purified biotinylated IgG dissolved in PBS was added to each well to 1.0 μg / mL, and the mixture was kept at 4°C overnight. On the next day, unreacted antibodies were washed with a wash buffer, streptavidin-HRP (1 / 5000 in PBS) was added, and the reaction was allowed to proceed at 4°C for 6 to 8 hours. After washing with washing buffer, TMB color development substrate was added, and the mixture was reacted at room temperature for 30 minutes under light protection. Color development was stopped by adding 1N H2SO4, and the sample was measured at 450nm by a plate reader.
[0149] Mitochondrial activation in the brain. Monitoring brain mitochondrial function by PET imaging using the [18F]BCPP-EF probe, which can detect mitochondrial complex I activity reflecting neuronal activity in the living brain, confirmed that p3-Alcβ increased neuronal activity in vivo. Mitochondrial dysfunction is often present in the brains of AD patients, and reduced activity in vulnerable brain regions can be detected by PET imaging with [18F]BCPP-EF.
[0150] Percutaneous microporation device. Figure 2A Examples of patches are described; Figure 2BThe patch application after percutaneous microperforation in the skin is shown. The microperforation device consists of (a) an applicator electrically connected to the filament, (b) a perforator having an upper substrate surface and defining a perforation area, and (c) a patch. A filament array having a plurality of filaments is arranged in the perforation area, and each filament is capable of conductively transferring heat energy to form at least one micropore in the tissue membrane via direct contact with the tissue membrane. The applicator provides a predetermined electrical energy to the filament to generate micropores, and applies the patch to at least a portion of the micropores. The patch (100) consists of a backing (200), a matrix (300) containing a composition (302) of p3-Alcβ and ingredients in a dry state, for example, and a release liner (400) that is removed before being applied to the perforated skin. The backing (200) may have an adhesive (201). The matrix (300) may consist of a matrix support (301) and a composition (302) arranged on the matrix support (301). After percutaneous microporation, the patch (100) is applied to the perforated skin after removing the release liner (400). The active ingredients in the composition (302) are dissolved by the interstitial fluid from the microchannels, and then the active ingredients migrate to the microchannels (percutaneous area) and then enter the blood circulation.
[0151] Patch manufacturing. Patches are manufactured based on distribution or tableting procedures known to those skilled in the art. Individual preparations utilize different ingredients as described herein. The patch includes a backing, a matrix, and a release liner, the matrix comprising non-aggregated peptides and ingredients disposed within the matrix, wherein the release liner is configured to be removed before being applied to the skin of the subject. The non-aggregated peptide is p3-Alcβ9-19. In the distribution method, all ingredients are dissolved in a water and ethanol mixed solvent. A predetermined amount of the ingredient solvent is distributed on a non-woven pad in a patch without a release liner. The distributed patch is moved to a drying chamber at 50°C until dry. The dried patch is taken out of the drying chamber and placed at room temperature for 30 minutes. The patch is covered with a release liner and then cut into a specified size. A separate patch is wrapped in an aluminum laminate bag with a desiccant. In the tableting method, all ingredients are mixed and weighed in a specified amount. The weighed powder is transferred to a die punch of a specified size for a compressor. The mold is set on the machine and compressed. Take the thin rectangular tablet and place it on the nonwoven pad in the patch without the release liner. Cover the patch with the release liner and then cut it into the specified size. Wrap the individual patches in an aluminum laminate bag along with the desiccant.
[0152] Example 1. Administration routes of p3-Alcβ
[0153] Non-parenteral administration route. p3-Alcβ9-19 (5 mg / head) was administered orally, nasally, or passively transdermally in rats. No absorption was observed in all administrations. p3-Alcβ9-19 is a hydrophilic peptide and its molecular weight is 1256 Daltons. These physicochemical properties may affect the poor membrane permeability through the gastrointestinal tract, nasal cavity, and stratum corneum.
[0154] Parenteral Routes of Administration. Figure 3A , Figure 3B and Figure 3C Shown are the PK profiles of p3-Alcβ9-19 following intravenous and subcutaneous administration in rats (mean±SE, n=4). Figure 3A Shown is a line graph depicting the PK profile of p3-Alcβ9-19 following intravenous administration (1 mg / body and 2 mg / body) in rats; Figure 3B A line graph depicting the PK profile of p3-Alcβ9-19 following subcutaneous administration (1 mg / body to 10 mg / body) is shown; Figure 3C A logarithmic scale graph depicting the PK profile of p3-Alcβ9-19 is shown. Figure 4A Shown is a line graph depicting the dose response of p3-Alcβ9-19 following intravenous and subcutaneous administration in rats; Figure 4B Shown is a line graph depicting the dose response of p3-Alcβ9-19 following subcutaneous administration in rats (mean±SE, n=4).
[0155] The PK characteristics of intravenous (IV) and subcutaneous (SC) injections showed rapid absorption and rapid elimination in rats. The blood concentration in SC was slightly more persistent than IV, but it disappeared within 1 hour. Dose-dependent increases were observed in both IV and SC injections. The bioavailability in SC may be similar to or slightly higher than IV injection.

[0163] The p3-Alcβ9-19 delivery using percutaneous microporation showed a higher aBA of 545% to 889% compared to IV (2 mg / body). A dose-dependent increase was observed for the percutaneous microporation system. Even compared to IV and SC injections, microporation delivery was the highest. This suggests that the parenteral route may be affected by the in vivo stability of p3-Alcβ9-19, and that microporation delivery can avoid the first-pass effect (metabolism) and maintain the release of p3-Alcβ9-19, rather than injection showing higher bioavailability.

[0180] Fig. 6A and Figure 6B It was shown that when an IR formulation containing p3-Alcβ9-19 was administered to mice using a transdermal microporation device ( Figure 5A ) or SR preparation ( Figure 5B ), changes in the concentration of p3-Alcβ9-19 in plasma and cerebrospinal fluid (CSF). Tables 2 and 3 show that when an IR preparation containing 1 mg of p3-Alcβ9-19 is administered to mice, the maximum blood concentration (Cmax) is about 600 ng / mL 1 hour after administration, and the blood concentration is maintained at about 300 ng / mL for up to 6 hours. In CSF, >20 ng / mL is shown 3 hours after administration, and a concentration of about 5 ng / mL is detected after 6 hours. This indicates that the transfer rate of p3-Alcβ9-19 from blood to CSF is about 3.5% (BA in CSF / BA in plasma × 100%) of good central transfer. The SF preparation shows sustained plasma concentrations in mice, and the CSF concentration is close to the detection limit.
[0181] Example 3. Pharmacological effects of p3-Alcβ percutaneous microporation in monkeys
[0182] In this example, two patch formulations of the present disclosure are illustrated. It is shown that the use of an IR patch is considered to be preferred for achieving effective enhancement of mitochondrial activity.
[0183] The mitochondrial activation effect of p3-Alcβ9-19 percutaneous microporation was studied in rhesus monkeys. The preparations used for the study are shown in Table 8 below. As a result, [18F]BCPP-EF accumulation, i.e., mitochondrial activation, was observed by PET measurement 1.5 hours after p3-Alcβ9-19 was administered using percutaneous microporation. In addition, activation continued in some areas even after 6.5 hours.

Percutaneous microporation applied 400 density and 4mJ / filament for IR formulations and 100 density and 3mJ / filament for SR formulations. An increase in mitochondrial activity (marked with a red rectangle) was found in monkeys, with an immediate response (early) 1 hour after the IR formulation containing p3-Alcβ9-19 was applied, and a slow response (delay) 6.5 hours after the SR formulation containing p3-Alcβ9-19 was applied compared to the control (vehicle).

On the other hand, the microporation conditions (50≤density≤200density and <4mJ / filament) provided a sustained PK profile for p3-Alcβ.
