CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority benefit of U.S. Application No. 17/806,363 filed June 10, 2022, the entire contents of which is incorporated herein by reference in its entirety.

FIELD

[0002] The present invention relates to methods and compositions that induce the expression of sulfotransferase in the hair follicle. Topical compositions containing agents that bind to the transcription factors that mediate the xenobiotic response in cells (e.g., PDX and CAR) are described. Up-regulation of sulfotransferase is beneficial to activate certain prodrugs that require sulfonation to become activated. One such drug is minoxidil used to treat androgenetic alopecia. The present invention is directed to methods for treating, reducing or preventing alopecia and other hair loss disorders by applying a sulfotransferase inducing composition on the scalp prior to treatment with minoxidil. Additional embodiments relate to compositions and kits that diagnose and control hair follicle stem cell differentiation. Methods and compositions are described that modify hair follicle stem cells intracellular pH thus controlling hair follicle stem cell differentiation. In some instances, increase of hair follicle stem cells intracellular pH induces and/or increases the sulfotransferase enzymatic activity in hair follicle cells. Induction of the sulfotransferase enzyme in hair follicles increases the sulfonation capacity of minoxidil; thus, increasing the response level to oral and topical minoxidil in the treatment of alopecia.

BACKGROUND

[0003] In 1988 the US FDA approved 2% topical minoxidil solution as an OTC drug for the treatment of androgenetic alopecia (AGA). Since the FDA approval, minoxidil has become the mainstay therapy for AGA. However, the effectiveness of minoxidil in the general population is low, only 39% of patients respond to the drug (See Olsen EA, Whiting D, Bergfeld W, Miller J, Hordinsky M, Wanser R, et al. A multicenter, randomized, placebo-controlled, double-blind clinical trial of a novel formulation of 5% minoxidil topical foam versus placebo in the treatment of androgenetic alopecia in men. J Am Acad Dermatol. 2007 57(5):767-74). In the pivotal study submitted to the US FDA in support of the efficacy of the 5% topical minoxidil foam, no subjects had great improvement, 8% of the subjects had a moderate improvement, and 31% of the subjects had a slight improvement (See US FDA Application 21-812 Medical Review).

[0004] Minoxidil is a pro-drug converted to its active form, minoxidil sulfate, by sulfotransferase enzymes present in the outer root sheath (ORS) of hair follicles (See Buhl AE, Waldon DJ, Baker CA, Johnson GA Minoxidil sulfate is the active metabolite that stimulates hair follicles. J Invest Dermatol. 1990 Nov; 95(5):553-7). It has been demonstrated that the activity of sulfotransferase in the ORS determines the clinical response to minoxidil (See Goren A, Castano JA, McCoy J, Bermudez F, Lotti T. Novel enzymatic assay predicts minoxidil response in the treatment of androgenetic alopecia. Dermatol Ther. 2014;27(3): 171-3). Sulfotransferase enzymes are expressed in abundance in the human liver. In the human liver, sulfotransferase is part of the Phase II enzymatic system that reduces xenobiotic toxicity (See Jancova P, Anzenbacher P, Anzenbacherova E. Phase II drug metabolizing enzymes. Biomed Pap Med Fae Univ Palacky Olomouc Czech Repub. 2010; 154(2): 103- 16).

[0005] Xenobiotics are extrinsic chemical substances (e.g., drugs), which may be present in human body (See Croom E. Metabolism of xenobiotics of human environments. Prog Mol Biol Transl Sci 2012; 112:31-88). They are included into specific metabolic pathways evolved to mitigate toxicity to an organism. Xenobiotic metabolism includes several pathways designed to modify chemical structure and decrease the toxicity of the compounds. Although, in some instances, the intermediates in xenobiotic metabolism may themselves cause toxic effects (See Bunchomtavakul C, Reddy KR Acetaminophen (APAP or N-Acetyl-p- Aminophenol) and Acute Liver Failure. Clinics in Liver Disease 2018; 22(2):325-346). Xenobiotic metabolism is divided into 3 phases, organized to modify lipophilic compounds into hydrophilic conjugates that can more readily be excreted. In Phase I, lipophilic xenobiotic molecules are metabolized by enzymes such as cytochrome P450 oxidases, which introduce polar groups and provide sites for downstream conjugation reactions. Phase I reactions are mainly localized in the liver. In Phase II, conjugating enzymes interact with metabolites produced by Phase I enzymes and eliminate them through both passive and active transport. Conjugating enzymes include a large group of bro ad- specificity transferases, with glutathione S -transferases as the most important representatives (See Jakoby WB, Ziegler DM. The enzymes of detoxication. J Biol Chem 1990; 265(34):20715-20718). After conjugation, any xenobiotic conjugates or their metabolites not eliminated in Phase II are further processed and eliminated in Phase III by transporter proteins.

[0006] Several Phase I and II metabolizing enzymes are known to be inducible by both endogenous and xenobiotic molecules. The most widely studied drug-metabolizing enzyme, by far, is the cytochrome P450 family. Many of the members of the cytochrome P450 family are inducible via nuclear receptor mediated induction. For example, cytochrome family 1 genes are up-regulated by the aryl hydrocarbon receptor (AhR) after it binds aromatic hydrocarbon ligands (See Gonzalez FJ, Liu SY, Yano M. Regulation of cytochrome P450 genes: molecular mechanisms. Pharmacogenetics 1993; 3(1): 51-57). Similarly, sulfotransferases have been demonstrated to be regulated by endogenous hormones (See Runge-Morris M, Kocarek TA, Falany CN. Regulation of the cytosolic sulfotransferases by nuclear receptors. Drug metabolism reviews 2013; 45(1): 15-33) and xenobiotics (See Runge-Morris M, Kocarek TA Regulation of sulfotransferases by xenobiotic receptors. Curr Drug Metab 2005; 6(4): 299-307.

[0007] Minoxidil sulfate is required for both the promotion of hair regrowth and the vasodilatory effects of minoxidil. Sulfotransferase enzymes are located in both the skin and the liver and are important Phase II xenobiotic metabolizing enzymes for a number of phenolic molecules including minoxidil (See Nimmagadda D, Cherala G, Ghatta S. Cytosolic sulfotransferases. Indian J Exp Biol 2006; 44(3): 171- 182).

[0008] Xenobiotic-metabolizing enzymes are important for the metabolism, elimination or detoxification of xenobiotics. Various nuclear receptors including aryl hydrocarbon receptor (AhR) and constitutive androstane receptor (CAR) regulate the gene expressions of Xenobiotic- metabolizing enzymes (See Xu, C., Li, C.Y., Kong, AN., 2005. Induction of phase I, II and III drug metabolism/transport by xenobiotics. Arch. Pharm. Res. 28, 249-268). Upon ligand binding, AhR forms a heterodimer with the AhR nuclear translocator (Amt), and the AhR-Amt complex binds to specific xenobiotic responsive elements and activates a battery of genes including members of cytochrome P450 family 1 (CYP1), such as CYP1A1, CYP1A2, CYP1B 1, and UDP-glucuronosyltransferases (UGT) 1A1, 1A6, 1A7 and 1A9 involved in the detoxification and elimination of xenobiotics as well as certain endogenous steroids. CAR and pregnane X receptor (PXR) are nuclear receptors that form functional heterodimers with the retinoid X receptor (RXR) (See Honkakoski, P., Sueyoshi, T., Negishi, M., 2003. Drug-activated nuclear receptors CAR and PXR. Ann. Med. 35, 172-182.). CAR and PXR are responsible for the xenobiotic-mediated induction of many genes including CYP1A, 2B, 2C and 3A families, UGT1A1 and 1A3, and sulfotransferase (SULT) 1A1 and 2A1 (See Handschin, C., Meyer, U.A., 2003. Induction of drug metabolism: the role of nuclear receptors. Pharmacol. Rev. 55, 649-673 and Maglich, J.M., Stoltz, C.M., Goodwin, B., Hawkins-Brown, D., Moore, J.T., Kliewer, S.A., 2002. Nuclear pregnane x receptor and constitutive androstane receptor regulate overlapping but distinct sets of genes involved in xenobiotic detoxification. Mol. Pharmacol. 62, 638-646). Additionally, 3'- phosphoadenosine 5'-phosphosulfate (PAPS) synthase (PAPSS), which catalyzes the biosynthesis of PAPS, which serves as the universal sulfonate donor compound for all sulfotransferase reactions is regulated by PXR and CAR (See Owen BM, Milona A, van Mil S, Clements P, Holder J, Boudjelal M, Cairns W, Parker M, White R, Williamson C. Intestinal detoxification limits the activation of hepatic pregnane X receptor by lithocholic acid. Drug Metab Dispos. 2010 Jan; 38(1): 143-9. and Alnouti Y, Klaassen CD. Regulation of sulfotransferase enzymes by prototypical microsomal enzyme inducers in mice. J Pharmacol Exp Ther. 2008 Feb; 324(2):612-21).

[0009] Many compounds have been reported to bind to nuclear factors and induce or suppress the expression of xenobiotic-metabolizing enzymes. For a comprehensive list See A. Parkinson, B.W. Ogilvie, D.B. Buckley, F. Kazmi, M. Czerwinski, 0. Parkinson, Biotransformation of xenobiotics, in: C. Klaassen (Ed.), Casarett & Doull's Toxicology, The Basic Science of Poisons, McGraw-Hill Education, New York, NY, USA, 2013, pp. 185-366.

[0010] Additionally, altering intracellular or extracellular pH is an important regulatory mechanism, which can influence cellular function and lead to cell differentiation in a range of stem cells (See Charruyer A, Ghadially R. Influence of pH on Skin Stem Cells and Their Differentiation. Curr Probl Dermatol. 2018; 54:71-78). Cell differentiation is associated with the altered expression of many proteins including xenobiotic-metabolizing enzymes. Specifically, increased sulfotransferase is a marker for keratinocyte differentiation (See, Johnson GA, Baker CA, Knight KA Minoxidil sulfotransferase, a marker of human keratinocyte differentiation. J Invest Dermatol. 1992 May; 98(5):730-3).

[0011] All studies to date exploring nuclear factors ability to induce or suppress the expression of xenobiotic-metabolizing enzymes have been conducted in cultured liver cells, cultured colon cells, or in mice. In order to determine the induction of xenobiotic-metabolizing enzymes in scalp tissues new methodologies will need to be employed. One such technology is a colorimetric assay for detecting sulfotransferase in plucked hair samples described in U.S. Patent No. 8,691,518, which is incorporated herein in its entirety by reference.

[0012] Many methodologies exist for increasing the dermal penetration of active ingredients through the stratum comeum (SC). For example, the use of penetration enhancing chemical agents have been described (See Trammer H, Neubert RH. Overcoming the stratum comeum: the modulation of skin penetration. A review. Skin Pharmacol Physiol. 2006; 19(2): 106- 21). However, many of these agents alter the structure of the SC aggressively and can lead to irreversible damage to the SC. An alternative approach to the use of SC modifying agents is the use of encapsulation techniques (See Tiwari N, Osorio-Blanco ER, Sonzogni A, Esporrin-Ubieto D, Wang H, Calderon M. Nanocarriers for Skin Applications: Where Do We Stand? Angew Chem Int Ed Engl. 2022 Jan 17; 61(3):e202107960). Such techniques surround the active ingredients with carrier molecules sharing similar morphology to cellular membranes that interact more gently with the SC and can be used to deliver large payloads. Such systems are more biocompatible and offer advantages such as biodegradability and low toxicity. Many examples of such encapsulation techniques have been described - for example, liposomes, micelles, nanogels, lipid nanoparticles, selenium nanoparticles, bilosomes, dendrimers and carbon nanotubes. Unfortunately, the use of encapsulation technologies introduces additional challenges to the production of a stable topical formulas. Many of the encapsulating systems used are susceptible to hydrolysis, oxidation, and aggregation or breakdown of the macro encapsulation structure. As such, novel formulation technologies are required to successfully implement a stable and operational topical formula containing encapsulated actives.

SUMMARY

[0013] Compositions and methods are disclosed herein for inducing (up-regulating) the expression of sulfotransferases in hair bearing skin, hair follicles, and/or keratinocyte cells, e.g., the scalp. In addition, compositions, methods, and kits are disclosed herein for controlling hair follicle stem cell differentiation. In some instances, the compositions and methods induce (up- regulate) the expression or activity of sulfotransferases in hair bearing skin, hair follicles, and/or keratinocyte cells. Increasing sulfotransferase is beneficial for metabolizing pro-drugs that require sulfonation to be activated, e.g., minoxidil sulfate is the active metabolite of minoxidil. Combining the composition described herein with topical minoxidil would be a more efficacious treatment for androgenetic alopecia. For example, embodiments of the methods and compositions disclosed herein can be used to increase the metabolism of minoxidil (which can result in the increase of bioavailable minoxidil sulfate) in hair follicles of patients suffering from a form of alopecia.

Additionally, an example of a topical composition, a shampoo, used to increase sulfotransferase in the scalp is described. Furthermore, methodologies for creating a stable topical formula containing an encapsulated active ingredient are described. In other instances, the compositions and methods alter the hair follicle stem cells pH and thus slows hair growth. This can be beneficial to slow normal hair growth so people could shave less frequently.

DETAILED DESCRIPTION

[0021] Androgenetic alopecia (AGA) is a common dermatological condition affecting approximately 50% of the population by the age of 50. Currently, the only drug approved by the US Food and Drug Administration (FDA) for the treatment of AGA in both men and women is topical minoxidil. Clinical trials have demonstrated that following 16 weeks of 5% minoxidil therapy approximately 30-40% of patients regrow hair.

[0022] While the exact mechanism of action of minoxidil in the treatment of AGA is not completely understood, research has demonstrated that minoxidil sulfate is the active compound that stimulates hair follicles. Minoxidil is converted to its active form, minoxidil sulfate, in the outer root sheath of the hair follicle by endogenous sulfotransferase enzymes utilizing 3'- phosphoadenosine 5'-phosphosulfate (PAPS). PAPS is produced in cells utilizing 3'- phosphoadenosine 5'-phosphosulfate synthase (PAPSS). Several studies have reported a correlation between sulfotransferase activity in plucked hair follicles and minoxidil response for AGA patients. In theory, increasing sulfotransferase or PAPS in the scalp would increase the likelihood that a subject will respond to topical minoxidil (thereby increasing the efficacy of a topical minoxidil); however, this has not been demonstrated in clinical studies. Further, in medicine, the induction of a deficient enzyme frequently does not result in a clinical benefit. For example, the pro-drug acyclovir used for the treatment of HS V is activated by the human thymidine kinase enzyme; however, while the induction of the thymidine kinase enzyme in-vitro activates acyclovir, in human studies thymidine kinase enzyme induction does not convert non-responders to acyclovir into responders. As noted herein, minoxidil compositions can be used to treat forms of alopecia. Thus, increasing the efficacy of minoxidil (which can involve converting androgenetic alopecia patients who are non-responders into responders to minoxidil) can improve hair growth (including hair diameter) of subjects using topical minoxidil. In addition, methods and compositions disclosed herein for increasing the efficacy of minoxidil for treatment of forms of alopecia can accelerate hair growth of subjects using topical minoxidil.

[0023] Biological sulfation is the conversion of the very stable oxy-anion sulfate to the high-energy sulfate donor 3'-phospho-adenosine-5'-phosphosulphate (PAPS). Sulfation of a variety of biomolecules depend on availability of the precursor PAPS, which is rate-limiting. In mammals, PAPS is synthesized in two steps by a bi-functional enzyme called PAPS synthetase (PAPSS). The synthesis of PAPS from inorganic sulfate and ATP is catalyzed by PAPSS. The sources of inorganic sulfur in nature are broad but include cysteine, 1 -cysteine, hydrogen sulfide, elemental sulfur, sulfite, thiosulfate, and various polythionates (e.g., tetrathionate).

[0024] In one embodiment, the invention concerns up-regulating the sulfonating capacity of hair bearing skin by applying a topical solution containing a source of inorganic sulfur to increase the concentration of PAPS. Examples of sources of inorganic sulfur include but are not limited to cysteine, 1 -cysteine, hydrogen sulfide, elemental sulfur, sulfite, thiosulfate, and various polythionates (e.g., tetrathionate). Additionally, a sulfate salt may be used, for example magnesium sulfate or sodium sulfate.

[0025] As used herein, the terms "prevent" or "prevention" and other derivatives of the words, when used in reference to alopecia, e.g., androgenetic alopecia, refer to a reduced likelihood of alopecia in an individual receiving a given treatment relative to that of a similar individual at risk for alopecia but not receiving that treatment. As such, the terms "prevent" and "prevention" encompass a treatment that results in a lesser degree of alopecia, e.g., androgenetic alopecia, than would be otherwise expected for a given individual. Efficacy for prevention of alopecia, e.g., androgenetic alopecia, can be established through controlled studies, e.g., in which a subject is administered a treatment (e.g., a topical treatment) and another subject is administered a placebo. Under these circumstances, if the subject treated with the topical treatment undergoes less hair loss over time relative to the subject receiving the placebo, e.g., at least 5% less, at least 10% less, at least 15% less, at least 20% less, at least 25% less, at least 30% less, at least 35% less, at least 40% less, at least 45% less, at least 50% less or beyond, the treatment is effective for the prevention of alopecia, e.g., androgenetic alopecia.

[0026] As used herein, the terms "treat," "treatment," or "treating" refer to therapeutic treatments, wherein the object is to reverse, alleviate, ameliorate, inhibit, slow down or stop the progression or severity of a disease or condition, e.g., androgenetic alopecia or other form of alopecia. The term "treating" includes reducing or alleviating at least one adverse effect or symptom of a disease or condition, e.g., androgenetic alopecia or other form of alopecia. Treatment is generally "effective" if one or more symptoms are reduced. Alternatively, treatment is "effective" if the progression of a disease is reduced or halted. That is, "treatment" includes not just the improvement of symptoms, but also a cessation of, or at least slowing of, progress or worsening of symptoms compared to what would be expected in the absence of treatment. Beneficial or desired clinical results include, but are not limited to, alleviation of one or more symptom(s), diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, remission (whether partial or total), and/or decreased mortality. For example, treatment is considered effective if the extent or amount of hair loss is reduced, or the progression of hair loss is slowed or halted. The term "treatment" of a disease also includes providing relief from the symptoms or side-effects of the disease (including palliative treatment).

[0027] As used herein the term "comprising" or "comprises" is used in reference to compositions, methods, etc. refers to component(s) or method steps that are present in the method or composition, yet allows for the composition, method, etc. to also include unspecified elements. [0028] The term "consisting of refers to compositions, methods, and respective components thereof as described herein, which are exclusive of any element not recited in that description of the embodiment.

[0029] As used herein the term "consisting essentially of refers to those elements required for a given embodiment. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

[0030] As used herein the term "alopecia" refers to all forms of hair loss in men and women including but not limited to traction alopecia, androgenetic alopecia, male pattern baldness (MPB), female pattern hair loss (FPHL), alopecia areata, alopecia universalis, telogen effluvium, chemotherapy induced alopecia, hair shedding, eyebrow hair loss, beard hair loss, hair thinning, etc.. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

[0031] As used herein the term "alkalinizing agent" refers to all agents that either: (i) directly increase the intracellular pH (ii) indirectly increase the intracellular pH by activating or inhibiting the various ion carriers that regulate cellular pH (iii) upregulate or downregulate the various ion carriers; or (iv) increase the intracellular pH by changing the extracellular pH. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

[0032] As used herein the term "acidifying agent" refers to all agents that either: (i) directly decrease the intracellular pH (ii) directly decrease the intracellular pH by activating or inhibiting the various ion carriers that regulate cellular pH (iii) upregulate or downregulate the various ion carriers; or (iv) decrease the intracellular pH by changing the extracellular pH. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

[0033] As used herein the term "ion carriers" refers to all cellular ion carriers that either increase or decrease the intracellular pH. In the context of this application ion carriers can be referred to as proton pumps. The term permits the presence of elements that do not materially affect the basic and novel or functional characteristic(s) of that embodiment.

[0034] The singular terms "a," "an," and "the" include plural referents unless context clearly indicates otherwise. Similarly, the word "or" is intended to include "and" unless the context clearly indicates otherwise. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of this disclosure, suitable methods and materials are described below. The abbreviation, "e.g." is derived from the Latin exempli gratia, and is used herein to indicate a non-limiting example. Thus, the abbreviation "e.g." is synonymous with the term "for example."

[0035] Various aspects of the technology described measuring the sulfonating ability of a hair bearing skin, hair follicle, and/or keratinocyte cell. An increase in the sulfonating ability of a hair bearing skin, hair follicle, and/or keratinocyte cell can be interpreted to mean that enzymes or substrates required for this reaction have been increased in concentration, i.e., an increase in substrates will lead to an increase in reaction products (Le Chatelier's principle). For example, increasing the available sulfotransferase will increase the sulfonating ability of a hair bearing skin, hair follicle, and/or keratinocyte cell. Similarly, increasing the available PAPS or PAPSS (which produces PAPS) will increase the sulfonating ability of a hair bearing skin, hair follicle, and/or keratinocyte cell.

[0036] Measurement of the sulfonating ability of a hair bearing skin, hair follicle, and/or keratinocyte cell or a hair follicle can be performed, if necessary, via a colorimetric assay adapted for that purpose. Examples are described in, e.g., Goren A, Shapiro J, Roberts J, McCoy J, Desai N, Zarrab Z, Pietrzak A, Lotti T. Clinical utility and validity of minoxidil response testing in androgenetic alopecia. Dermatol Ther 2015: 28(1): 13-16, ("the Minoxidil Response Test") which is incorporated herein in its entirety by reference. Briefly, plucked anagen hairs are collected from the scalp and inspected visually for an intact bulb. Suitable hairs are trimmed to a length of -1 cm and immersed, bulb first, in 100 pL of an assay solution containing 50 mM phosphate buffer (pH8), 5 mM potassium p-nitrophenyl sulfate, 20 pM adenosine 3',5'-diphosphate, 100 pM minoxidil and 5 mM MgC12. Hairs are allowed to react with the solution for 24 hours at room temperature. After incubation, hairs are removed and the optical absorbance of the solution at 405 nm is determined with a spectrophotometer (e.g., Shimadzu UV-1700, Kyoto, Japan) using a single scan and 1 cm path length.

[0037] Increased intracellular pH is necessary for adult epithelial and embryonic stem cell differentiation. Various aspects of the invention describe the increased or decreased rate of hair follicle stem cells (HFSC), rate of differentiation, and/or proliferation. An increase in intracellular pH (pHi) can be used to increase the rate of hair follicle stem cells (HFSC) rate of differentiation and/or proliferation. Similarly, a decrease in intracellular pH (pHi) can be used to decrease the rate of hair follicle stem cells (HFSC) rate of differentiation and/or proliferation. In one aspect of the invention, pHi can be changed by changing the extracellular pH (pHe).

[0038] Applicants disclose herein methods to treat or prevent various forms of alopecia, e.g. female pattern hair loss or androgenetic alopecia. The method includes the use of a topical composition applied to the scalp that up-regulates the sulfonating capacity of the hair follicle. The method further includes the use of topical minoxidil applied subsequent to a topical composition applied to the scalp that up-regulates the sulfonating capacity of the hair follicle.

[0039] Additionally, applicant discloses herein methods for slowing hair growth. The methods include application of an acidifying agent to the HFSC niche subsequently reducing the HFSC pHi.

[00119] In cases where encapsulation techniques have been implemented in the above embodied formulations - for example, liposomes, micelles, nanogels, lipid nanoparticles, selenium nanoparticles, bilosomes, dendrimers and/or carbon nanotubes - the stability of the formula will require optimization to prevent degradation. For example, liposomes are vesicle structures created from one (unilamellar) or more bilayers of amphipathic lipids. In such systems lipids are often in direct contact with aqueous solution and are subject to hydrolysis (the breakdown of lipids from water moisture) and oxidation (degradation of lipids due to the loss of electrons). Similarly, delivery systems using encapsulation techniques are optimized for stratum comeum penetration via the size of the encapsulated structure. For example, structural instabilities such as aggregation or the conversion of unilamellar structures to multilamellar or other liposome structures in solution would decrease the efficacy of payload delivery through skin.

[00120] Many measurement techniques have been described to track the degradation of encapsulated structures for formula stability optimization. For example, subsequent to hydrolysis, free fatty acids are produced and can be detected with UV-visible (UV/Vis) spectroscopy. UV/Vis spectroscopy can also be used to detect peroxidized lipids if oxidative degradation has occurred in a formula. Vesicle structural instabilities can be monitored by probing the hydrodynamic radius of liposomes with the techniques of dynamic light scattering, cryogenic transmission electron microscopy, and small-angle neutron scattering.

[00121] Formulas utilizing encapsulation techniques to increase dermal penetration can be optimized by adjusting pH, temperature, and particle size (extrusion). In one embodiment of the present invention, a liposomal solution is stabilized by adjusting the pH to a range of 7-11. In another embodiment the pH is adjusted to a range of 7.5 to 10. In yet another embodiment, a liposomal solution is stabilized by adjusting the pH to a range of 8.0-8.7. In one embodiment a buffering solution, for example, acetate, citrate, or HEPES is used to stabilize the pH of a liposomal solution. In another embodiment, a Tris buffer is used. In another embodiment, a carbonate buffering or a phosphate buffering system is used. In one embodiment of the present invention, a liposomal solution is stabilized by adjusting the pH to a range of 8.0-9.0 using a Tris buffer.

[00122] In one embodiment of the present invention a buffering system for increasing the shelf-life of a liposomal solution is optimized using UV-visible (UV/Vis) spectroscopy measurements over time. In yet another embodiment, samples of optimized liposomal solutions are stored at elevated temperatures to accelerate degradation prior to UV- visible (UV/Vis) spectroscopy measurements over time.

[00123] In one embodiment of the present invention, oxidative degradation of a liposomal solution is prevented by the addition of an antioxidant. In one embodiment, oxidative degradation of a liposomal solution is prevented by the addition of ascorbic acid, monothioglycerol, potassium metabisulfite, sodium bisulfite, sodium formaldehyde sulfoxylate, sodium sulfite, sodium thiosulfate, tocopherol, sodium metabisulfite, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), ascorbyl palmitate, or propyl gallate. In one embodiment, oxidative degradation of a liposomal solution is prevented by the addition of acai oil, alpha lipoic acid, green tea extract, retinal, vitamin C, coenzyme Q10 (Co Q-10), isoflavones, polyphenols, curcumin, turmeric, pomegranate, rosemary extract, glutathione, selenium, or zinc. In yet another embodiment of the present invention, the composition includes a chelating molecule, for example ethylenediaminetetraacetic acid (EDTA), disodium EDTA, tetrasodium EDTA, pentasodium penetate, sodium metasilicate and phosphate derivatives, etidronic acid and its derivatives, or galactaric acid. These chelating agents can be added to capture free radicals in solution and prevent oxidation of lipids in a liposomal containing formula.

[00124] In one embodiment of the present invention, a pH range is chosen such that it is optimal for preventing degradation of a liposomal solution and simultaneously within a range of pHs optimal for inducing the upregulation of SULTIAI. In another embodiment of the present invention, a pH range of 8.0-9.0 is used to both stabilize a liposomal solution and induce the expression of SULT I Al. In one embodiment of the present invention, a stable liposomal solution of encapsulated Tris buffer is used to induce the expression of SULTIAI in the outer root sheath of hair follicles. In another embodiment, a stable liposomal solution of encapsulated Tris buffer is prepared using Phosphatidylcholine (Phospholipon 90G). In another embodiment, a stable liposomal solution of encapsulated Tris buffer is prepared using Phosphatidylcholine (Phospholipon 90G) in an amount between I and 15% (w/w). In yet another embodiment, a stable liposomal solution of encapsulated Tris buffer is prepared using 2% (w/w) Phosphatidylcholine (Phospholipon 90G). In one embodiment of the present invention, a liposomal solution containing Phosphatidylcholine (Plospholipon 90G) is protected from hydrolysis and oxidation by adding a Tris buffer at a pH range of 8.0-8.7. In yet another embodiment of the present invention, a liposomal solution containing Phosphatidylcholine (Plospholipon 90G) is stabilized using a Tris buffer at a concentration of 100-500 mM. In another embodiment, a Tris buffer at a concentration of 500 mM - 1 M is used. In another embodiment of the present invention, a liposomal solution containing Phosphatidylcholine (Plospholipon 90G) is stabilized using a Tris buffer at a concentration of 250 mM or 3% (w/w). In another embodiment, a liposomal solution containing Phosphatidylcholine (Phospholipon 90G) and 250 mM or 3% (w/w) Tris is used to induce the expression of SULTIAI in the outer root sheath of hair follicles.

[00125] In one embodiment, liposomes comprising or consisting of phosphatidylcholine (available under the trade name: Phospholipon 90G) are used to encapsulate sodium bicarbonate (e.g. pH 10) or TRIS (e.g. pH 8). In s o me e mb o d ime nt s , sodium bicarbonate and/or TRIS, e.g. at pH 8, are used to up-regulate SULTIAI in vivo.

[00145] It is understood that, in certain cases, an ingredient may possess multiple functions. For example, the buffer system (e.g., TRIS/TRIS HC1 at basic pH) can also act as an alkalinizing agent, and the chelating agent (e.g. EDTA) and the inorganic sulfur source (e.g. sodium metabisulfite) can each also act as a preservative.

Use ofRXR, RAR, and other NR agonists

[00146] Embodiments of the invention can involve use of retinoid X receptor (RXR) agonists, retinoic acid receptor (RAR) agonists, and/or an agonist of another nuclear receptor (NR) in an RXR-NR heterodimer. For example, any one or combination ofRXR agonists, RAR agonists, and/or an agonist of another NR in an RXR-NR heterodimer can be used to treat or prevent hair loss (e.g., forms of alopecia), increase or improve hair growth, induce sulfotransferase, increase the efficacy of minoxidil, and/or convert androgenetic alopecia patients who are non- responders to minoxidil into responders. This can be achieved by using any one or combination of RXR agonists, RAR agonists, and/or an agonist of another NR in an RXR- NR heterodimer in accordance with any of the methods disclosed herein. As a non-limiting example, embodiments can involve use of an RXR agonist, a RAR agonist, and/or a RXR agonist with an agonist of another NR in an RXR- NR heterodimer to induce the expression of SULT1A1.

[00147] The retinoid X receptor (RXR) is an essential member of the steroid/thyroid hormone superfamily of nuclear receptors (NRs) that predominately function as transcription factors. The natural ligand of RXR was first proposed to be 9-cis-retinoic acid (9-cis-RA). However, many groups have been unable to detect endogenous 9-cis-RA in cells. All transretinoic acid (ATRA) had been discovered to be a ligand of RXR. Polyunsaturated fatty acids (PUFAs), such as docosahexaenoic acid (DHA) and a saturated metabolite of chlorophyll, phytanic acid are also identified as RXR ligands.

[00148] In the nucleus, RXR functions as a transcription factor. It binds to specific six-base-pair sequences of DNA in the promoter regions of genes. RXR functions as a dimer with either itself (homodimer) or another NR (heterodimer). Binding by the ligand of the NR partner defines the promoter site response element (RE) composed of two six base-pair sequences (half- sites) separated by a discrete number of bases to which the RXR-NR heterodimer binds.

[00149] Transcriptional activation by RXR-NR dimers can be classified into three categories: nonpermissive, permissive, and conditionally permissive heterodimers of RXR and another nuclear receptor (NR).

[00150] Examples of transcriptional activation by a nonpermissive heterodimeric partner include thyroid hormone receptor (TR) or vitamin D receptor (VDR). The nonpermissive NR is dominant so that binding by its agonist controls the transcriptional complex to initiate gene transcription from the nonpermissive-ligand responsive gene transcriptional start site. Binding of an RXR agonist would not enhance the response induced by the bound NR agonist.

[00151] Examples of transcriptional activation by a permissive RXR heterodimeric partner include pregnane x receptor (PXR), constitutive androstane receptor (CAR), famesoid (bile acid) X receptor (FXR), liver (oxysterol) X receptor (LXR), and peroxisome proliferator- activated receptor (PPAR). An agonist of either partner in the heterodimeric pair such as RXR- PPAR could bind its own NR initiate gene transcription. Binding of an agonist to the second NR in the dimer would enhance the transcriptional response induced by first NR-agonist complex either additively or synergistically.

[00152] Examples of transcriptional activation by the conditionally permissive heterodimeric partner can include retinoic acid receptor (RAR). Binding of the RAR agonist would control the transcriptional response and also permit the binding of an RXR agonist. Thus, the RAR-agonist complex would be permissive. The RXR-agonist complex would then enhance the transcriptional response induced by the RAR agonist.

[00153] As such, a ligand of either RXR or a NR may be used to initiate transcription of genes. Additionally, in the case of permissive and conditionally permissive transactivation, ligands of RXR or the NR can act synergistically to activate transcription.

[00154] In one embodiment of the present invention, a RXR agonist is used to induce the expression of SULT1A1. Examples of RXR agonists include but are not limited to 9- cis-retinoic acid, all trans retinoic acid, ATRA, retinal (or retinal or retinaldehyde), retin-A, (E)- 5,8,11,14, 17, 20-docosahexaenoic acid, lithocholic acid, phytanic acid, 9cUAB30, AGN194204, CD3254L, G100268, LG101305, methoprene acid, PA024, SRI 1217, SRI 1237 (BMS649), DECI, DR5III, PRIC295, bexarotene, CD3254, decosahexaenoic, flurobexarotene, LG 100268, LG 100754, isotretinoin, etc.

[00155] In another embodiment of the present invention, a RAR agonist is used to induce the expression of SULT1A1. Examples of RAR agonists include but are not limited to all- trans- retinoic acid, ATRA, retinal (or retinal or retinaldehyde), retin-A, 9-cis-retinoic acid, all-trans-5,6- epoxy retinoic acid, DR5III, isotretinoin, AC 261066, AC 55649, adapalene, AM 580, AM 80, BMS 753, BMS 961, BMS 453, CD 1530, CD 2314, CD 437, Ch 55, tazarotene, TTNPB, AR-7, FOXO1, SMRT, N-CoR, SMRTER, EC 19, etc.

[00156] In yet another embodiment of the present invention, a compound that may be metabolized by enzymes in the skin to become a RAR or RXR agonist is used to induce the expression of SULT1A1. Examples of a compound that will be metabolized to become agonists include but are not limited retinyl propionate, retinyl palmitate, or retinyl acetate.

[00157] In yet another embodiment of the present invention, a RXR agonist is used with an agonist of another NR in an RXR-NR heterodimer to induce the expression of SULT1A1. Examples of other NRs include thyroid hormone receptor (TR), vitamin D receptor (VDR), pregnane x receptor (PXR), constitutive androstane receptor (CAR), famesoid (bile acid) X receptor (FXR), liver (oxysterol) X receptor (LXR), peroxisome proliferator- activated receptor (PPAR), retinoic acid receptor (RAR), aryl hydrocarbon receptor (AhR), Nrf2, GR, etc.

[00158] In one embodiment, the invention concerns up-regulating the sulfonating capacity ofhair bearing skin, hair follicles, and/or keratinocyte cells by applying a topical solution containing a salt of minoxidil such that the one ion of the salt is an alkalinizing agent that will raise the intracellular pH of cells in the outer root sheath of the hair follicle and the counter ion is minoxidil. Examples of alkalinizing slats of minoxidil include, but are not limited to, minoxidil bicarbonate, minoxidil citrate, minoxidil carbonate, minoxidil lactate, and minoxidil acetate. In one embodiment the salt is formulated with a penetration enhancer.

[00159] The therapeutic agents, particularly an alkalinizing agent, described herein and used in the present methods may be formulated into compositions according to the knowledge of one of skill in the art. In one embodiment, the alkalinizing agents or other inducer of sulfotransferase is encapsulated in order to increase the water solubility of the therapeutic agent. In one embodiment, the alkalinizing agents or other inducer of sulfotransferase is encapsulated in order to decrease the water solubility of the therapeutic agent. In another embodiment, the alkalinizing agents or other inducer of sulfotransferase is encapsulated in order to reduce the loss through degradation of therapeutic agent, for example, to reduce oxidation of the therapeutic agent. In another embodiment, the alkalinizing agents or other inducer of sulfotransferase is encapsulated in order to promote penetration through the stratum corneum. In some embodiments the alkalinizing agent is placed in a liposome containing lecithin.

[00160] Efficacy of treatment to treat or prevent androgenetic alopecia can be determined by monitoring the density of hairs on a given area of the subject's body, e.g., a given area of the scalp. If the rate of hair loss is reduced, e.g., by 10% or more following treatment, the treatment is effective for the prevention of androgenetic alopecia. Similarly, if hair density remains the same, the treatment is effective for the prevention of androgenetic alopecia. If the density of hair increases, e.g., by 5% or more, e.g., by 10% or more following treatment, the treatment is also considered effective for the treatment and/or prevention of androgenetic alopecia.

[00161] Efficacy of treatment to treat or prevent androgenetic alopecia can be determined by monitoring global photography. For example, the patient or an expert can assess the treatment response utilizing before and after global photographs.

[00185] Example 1: In-vitro Evaluation of Sulfotransferase Up-Regulation

[00186] The following experiment was conducted to assess the up-regulation of sulfotransferase in hair follicles by candidate compounds know to interact with human nuclear receptors (e.g., PXR and CAR).

[00187] Method: For each compound tested, 24 hairs were plucked from a human subject. Hairs were visually inspected to confirm the presence of the hair bulb. 2 hairs were placed in to 12 clean sample tubes (i.e., two hairs per reaction) containing lOOuL of Williams' E media with 0.292g/L L-glutamine. Suitable candidate compounds were dissolved in DMSO such that when 1 uL of the compound solution was added to the sample media the final concentration of the compound was the concentration being studied (listed in the Results section). 1 uL of DMSO with no compound was added to control samples. Hairs were allowed to incubate with the candidate compounds for 24 h at room temperature. All samples were run in triplicate, i.e., the data describe in the result section is an average of three samples tested.

[00188] After 24h of incubation hairs were removed from the sample media and washed briefly with clean water. Hairs were trimmed to a length of - 1 cm and immersed, bulb first, in 100 pL of an assay solution containing 50 mM phosphate buffer (pH8), 5 mM potassium p- nitrophenyl sulfate, 20 M adenosine 3',5'-diphosphate, 100 pM minoxidil and 5 mM MgC12. Hairs were allowed to react with the solution for 24 hours at room temperature. After incubation, hairs were removed and the optical absorbance of the solution at 405 nm was determined with a spectrophotometer using a single scan and 1 cm path length.

[00192] A study was conducted on thirty human subjects (30 men) with low sulfotransferase activity as determined by colorimetric enzymatic test described by Goren et al. Subjects were recruited based on an enzymatic test result of OD<0.4 The subjects were randomized to an active group and a placebo group in a 1:1 ratio. All subjects applied 5% topical minoxidil once daily. The active group applied a shampoo containing hyperforin once a day prior to the use of minoxidil. The placebo group applied a vehicle shampoo. At the end of 1 week the average sulfotransferase activity of all subjects increased almost 3 fold (287%). The average sulfotransferase activity remained high for a follow-up period of 6 months. At 4 months, the average increase in hair counts in the active group was 166% higher than the placebo. In addition, 60% of the subjects in the active group responded to minoxidil compared to 0% of the placebo group. This demonstrates that embodiments of the method and compositions disclosed herein can convert androgenetic alopecia pateints who are non-responders to minoxidil into responders.

[00201] Summary - Conclusions:

[00202] Efficacy Results

[00203] The aim of the study was to evaluate the efficacy of AB- 103 as an adjuvant therapy to 5% topical minoxidil solution in the treatment of MPHL. A head-to-head prospective clinical study of 48 subjects treated for a minimum of 16 weeks was conducted. Subjects were randomized to two treatment arms: AB -103 administered concomitantly with topical minoxidil (treatment arm) or a vehicle shampoo administered concomitantly with topical minoxidil (comparator arm). Global photographers were evaluated by a blinded expert. The treatment response was rated on a 7 point scale as follows: -3 (significantly worse), -2 (moderately worse), -1 (slightly worse), 0 (no change), +1 (slightly improved), +2 (moderately improved) and +3 (significantly improved). The raw data from the CRFs was tabulated and graphed by an expert (refer to FIG. 1).

[00204] Eight subjects from the treatment arm and five subjects from the comparator arm did not complete the study. No reason was given for discontinuation; however, at the one week post discontinuation follow-up call none of these subjects reported adverse events. In total, 35 subjects completed the study.

[00205] The Mann- Whitney U test (MedCalc vl8.2. 1) was used to determine the effect of AB- 103 as an adjuvant minoxidil therapy in the treatment arm versus the vehicle shampoo in the comparator arm. The null and alternate hypothesis are given below:

Ho: The distributions of the subjects' treatment response in the treatment arm and the comparator arm are equal

HA: The distributions of the subjects' treatment response in the treatment arm and the comparator arm are not equal [00206] The results indicate the following:

Mann- Whitney U test (two-sided)

• Mann- Whitney U=93.5, p-value=0.0432; thus, the null hypothesis is rejected.

• Safety Results: No adverse events were reported in either arm.

[00207] Conclusion:

[00208] The distributions of the subjects' treatment response in the AB-103+minoxidil arm and the vehicle shampoo+minoxidil arm were significantly different (p-value=0.0432). In the AB-103+minoxidil arm 75% of subjects experienced hair growth versus 48% in the vehicle shampoo+minoxidil arm.

[00209] Note: In this sample population, the rate of response in the comparator arm (48%) was larger than one would expect from prior clinical studies (39%). While it is possible that the vehicle improved some subjects response, it is more likely that the higher response rate observed is due to the study' s small population size.

[00213] Efficacy Results

[00214] The aim of the study was to evaluate the efficacy of AB -103 in up-regulating the minoxidil sulfotransferase enzymes in human hair follicles in-vivo. A double blinded, placebo controlled prospective clinical study of 20 subjects treated for 7 days was conducted. Subjects were randomized to two treatment groups: AB- 103 shampoo or the shampoo vehicle. Sulfotransferase activity levels were determined utilizing the Minoxidil Response Test. The analysis was conducted with a spectrophotometer (Shimadzu UV-1700, Kyoto, Japan). The raw data from the CRFs was tabulated and graphed by an expert (refer to FIG. 2).

[00215] The independent samples t-test (MedCalc vl8.2. 1) was used to determine the effect of AB- 103 compared to the vehicle shampoo on follicular sulfotransferase activity. The null and alternate hypothesis are given below:

Ho: The mean change in sulfotransferase activity after 7 days of treatment with AB- 103 is equal to the mean sulfotransferase activity after 7 days of treatment with the vehicle shampoo

HA: The mean change in sulfotransferase activity after 7 days of treatment with AB- 103 is greater then the mean sulfotransferase activity after 7 days of treatment with the vehicle shampoo

Mathematically written as:

Ho: pl = p2

HA: pl > p2

[00216] The results indicate the following:

Independent samples t-test (two-sided)

* The D' Agostino-Pearson test for normal distribution (MedCalc vl8.2. 1) accepts normality of the differences with p=0.4278.

* The analysis of the dataset yielded t(18)=-2.839, p=0.0109; therefore, the results of t-test indicate that the null hypothesis is rejected and we conclude that there was a significant difference in the mean change in sulfotransferase enzyme activity between the AB-103 group (p=0.2413, sd=-0.2562) [95% CI: 0.05807 to 0.4246] and the placebo group (p=-0.008420, sd=- 0.1085) [95% CI: -0.08602 to 0.06918],

* The 95% CI for the difference in means is 0.06492 < pb - pa < 0.4346 with the best estimate being the mean difference = 0.2497.

Safety Results: No adverse events were reported in either group.

[00217] Conclusion: [00218] The mean change in sulfotransferase activity after 7 days of treatment with AB- 103 was significantly greater than the mean change following placebo treatment (p- value<0.0109). In addition, utilizing the data from report (FI-IVD-001) regulatory submission, we conclude that the increase in sulfotransferase activity was significantly larger than the within-subject variability of the MRT assay.

[00240] Assessing the Efficacy of Alkaline pH on Increasing Collicular Sulfotransferase.

[00241] Study 001

[00242] An in-vitro study was conducted to assess the efficacy of an alkaline pH solution on increasing follicular sulfotransferase. Twenty hairs were plucked from each subject. The baseline sulfotransferase activity of each subject was measured by analyzing 10 plucked hairs with an Minoxidil Response Test devised by Goren et al. The remaining 10 hairs were incubated with an alkaline solution (pH of 8.5) for a period of 24 hour at a temperature of 37 °C. Thereafter, the remaining 10 plucked hairs were analyzed with the Minoxidil Response Test devised by Goren et al. The data is summarized in Table 3 below. The average increase was approximately 100%.

Table 3 Efficacy of Alkaline pH on Increasing Collicular Sulfotransferase

[00243] Study 002

[00244] A study was conducted on thirty human subjects (30 men) with low sulfotransferase activity as determined by colorimetric enzymatic test described by Goren et al. Subjects were recruited based on an enzymatic test result of OD < 0.4. The subjects were randomized to an active group and a placebo group in a 1:1 ratio. All subjects applied 5% topical minoxidil once daily. The active group applied an alkaline solution (pH of 8.5) once a day prior to the use of minoxidil. The placebo group applied a vehicle solution (pH 7.0). At the end of 1 week, the average sulfotransferase activity of all subjects increased almost 2 fold (95%). The average sulfotransferase activity remained high for a follow-up period of 6 months. At 4 months, the average increase in hair counts in the active group was 192% higher than the placebo. In addition, approximately 50% of the subjects in the active group responded to minoxidil compared to 0% of the placebo group.

[00248] pHi Assay

[00249] Bromothymol Blue, 0.04% Aqueous solution was used as a pH indicator to visualize intracellular pH (pHi) of cells located in the Hair Follicle Stem Cell (HFSC) niche. In a neutral solution of pH 6.0- 7.6 Bromothylmol Blue appears green, below pH 6.0 it appears yellow, and above pH 7.6 it appears blue. Hair follicles were submerged in assay solution for approximately 5 minutes, until HFSCs were stained. Cells were visualized using a 20X magnification stereo microscope equipped with a 5MP Color Digital Eyepiece Microscope Camera.

Table 4. Composition/Information on Ingredients

[00250] pHi of HFSC

[00251] The following experiment was conducted to assess the intracellular pH of the HFSC niche in hair.

[00252] Method:

[00253] 1 hair was plucked from each human subject. Hairs were visually inspected to confirm the presence of the hair bulb and hairs were rinsed briefly with clean water. Hairs were then immersed, bulb first, in 100 pF of assay solution. Hairs were allowed to react with the solution for 5 minutes at room temperature. After incubation, hairs were removed and mounted on a clean glass slide and visualized using a 20X magnification stereo microscope equipped with a 5MP Color Digital Eyepiece Microscope Camera.

[00254] Results: See Table 5 of FIG. 5.

[00255] Conclusion: the intracellular pH of cells contained in the HFSC niche was below pH6.0

[00256] In vitro upregulation of SULT1 Al by increasing pH (24h)

[00257] The following experiment was conducted to assess the up-regulation of sulfotransferase in hair follicles by an increase in pHi.

[00258] Method:

[00259] For each pH tested, 36 hairs were plucked from a human subject. Hairs were visually inspected to confirm the presence of the hair bulb. 2 hairs were placed in to 9 wells (i.e., two hairs per reaction) of a sterile flat bottom tissue culture plate containing 250uL of Williams' E media with 0.292g/L L-glutamine at pH 5.9, 7.4, and 8.1 (i.e. 3 wells per pH). Hairs were incubated for 6 hours and 24 hours at 5% CO2, 100% relative humidity. All samples were run in triplicate, i.e. the data described in the results section is an average of three samples tested for each pH.

[00260] After 24 hours of incubation, hairs were removed from the sample media and washed briefly with clean water. Hairs were trimmed to a length of ~1 cm and immersed, bulb first, in 100 pL of an assay solution containing 50 mM phosphate buffer (pH8), 5 mM potassium p-nitrophenyl sulfate, 20 M adenosine 3',5'-diphosphate, 100 pM minoxidil and 5 mM MgC b. Hairs were allowed to react with the solution for 24 hours at room temperature. After incubation, hairs were removed and the optical absorbance of the solution at 405 nm was determined with a spectrophotometer using a single scan and 1 cm path length.

[00261] Results: See Tables 6-7 below.

Table 6. Incubation in media for 24 hour.

Table 7. Incubation in media for 6 hours.

[00262] Conclusion: Incubating hairs in growth medium above pH 7.0 was able to significantly upregulate sulfotransferase response in 24 hours, but not in 6 hours.

[00266] ImL of 10% solution of sodium bicarbonate in Dimethyl sulfoxide (DMSO) was applied to the scalp of each subject in a small quarter-sized area. 1 hair from within the area was plucked from each subject at time O (zero), 15, and 30 min. Hairs were visually inspected to confirm the presence of the hair bulb and were rinsed briefly with clean water. Hairs were then immersed, bulb first, in 100 pL of assay solution. Hairs were allowed to react with the solution for 5 minutes at room temperature. After incubation, hairs were removed and mounted on a clean glass slide and visualized using a 20X magnification stereo microscope equipped with a 5MP Color Digital Eyepiece Microscope Camera. [00267] Results: See Tables 8-10 of FIGS. 6-8.

[00268] Conclusion: Topical application of 10% sodium bicarbonate in DMSO was able to change the pHi of cells located in the HFSC niche within 30 minutes of application.

[00270] Sulfotransferase Upjegulation with Alkalizing Agents in Human Hair Follicle

[00271 ] Twenty-four (24) hairs were plucked from each human subject. Hairs were visually inspected to confirm the presence of the hair bulb. 2 hairs were placed in to an open 1.5mE tube (i.e., two hairs per reaction) containing 400 pF of Dulbecco's Modified Eagle's Medium/Nutrient Mixture F-12 Ham media with 0.365g/L E-glutamine, 1.2g/E NaHCOs, 5.18g/L CHES, pH 9.5. Hairs were incubated for O (baseline), 4, 8, 16, 20, and 24 hours at 37°C, 100% relative humidity. All samples were run in quadruplicate and the experiment was repeated four times, i.e. the data described in the results section is an average of four experiments with four samples tested for each time point.

[00272] After each time point of incubation, hairs were removed from the sample media and washed briefly with clean water. Hairs were trimmed to a length of ~1 cm and immersed, bulb first, in 100 pL of an assay solution containing 50 mM phosphate buffer (pH8), 5 mM potassium p-nitrophenyl sulfate, 20 p M adenosine 3',5'-diphosphate, 100 pM minoxidil and 5 mM MgCh. Hairs were allowed to react with the solution for 24 hours at room temperature. Referring to FIG. 9, after incubation, hairs were removed and the optical absorbance of the solution at 405 nm was determined with a spectrophotometer using a single scan and 1 cm path length.

[00282] Subjecting test devices to extreme temperature conditions is intended to simulate product degradation over time, but at an accelerated rate. Using the Arrhenius equation, shelf- life data can be extrapolated as a predictive measurement for product performance. The Arrhenius equation relates chemical reaction rate (k) to absolute temperature (Z): r/(In<')A/T=AE _a /RT ²

[00283] Where Ea is the activation energy and R is the universal gas constant.

Table 13: Arrhenius Model for Liposomal Containing Solution Stability

[00284] Using the Arrhenius model at 20 kcal, the test formula would have satisfactory performance theoretically for 1 years if specifications were met after 56.2 days at 50°C, or 112.3 days at 40 °C. [00285] The purpose of stability testing at 50°C and 40°C is to generate data to determine the shelf life of the product. The data is to be used as a predictor of stability for the final product form.

[00289] In Vivo Evaluation of SULT1A1 Expression After application of Formula and Gl and G2 (Liposomal Containing Solutions)

[00290] An in-vivo study was conducted to assess the efficacy of a liposome containing solution on increasing follicular sulfotransferase. 24 female subjects were recruited to the study. 10 hairs were plucked from each subject at baseline (day 0). The baseline sulfotransferase activity of each subject was measured by analyzing 10 plucked hairs with an Minoxidil Response Test devised by Goren et al. Subsequent to sulfotransferase baseline assessment each subject was instructed to apply a liposomal containing solution to their scalp once daily for seven days. 12 subjects applied Formula GI (Table 11) and 12 subjects applied Formula G2 (Table 12) [00291] After seven days of treatment, 10 plucked hairs from each subject were analyzed with the Minoxidil Response Test devised by Goren et al. The data is summarized in Table 18 below. The average increase was approximately 145% for Formula GI and 135% for formula G2.

Eiposomal Formulation

A liposomal formulation was prepared having the following composition:

[000293] The phase A components were mixed together at 55-70 °C until the solution was uniform and all powders were dissolved. The phase B components were added, and the solution was mixed until most of the B components were dissolved. The solution was then mixed with a rotor- stator homogenizer and cooled to room temperature. The C components were then mixed together in a separate container, and then added to the A-B liposome solution.

[00294] Subjecting test devices to extreme temperature conditions is intended to simulate product degradation over time, but at an accelerated rate. Using the Arrhenius equation, shelflife data can be extrapolated as a predictive measurement for product performance. The Arrhenius equation relates chemical reaction rate (k) to absolute temperature (1): rf(Ink)A T=AE _a /RT ²

[00295] Where Ea is the activation energy and R is the universal gas constant. Table 19: Arrhenius Model for Liposomal Containing Solution Stability

[00296] Using the Arrhenius model at 20 kcal, the test formula would have satisfactory performance theoretically for 1 years if specifications were met after 56.2 days at 50°C, or 112.3 days at 40°C.
