FIELD

[0001] This relates to formulations comprising dihydrohonokiol-B (DHH-B), or a derivative or analog thereof, for treating sedative, hypnotics, or anxiolytic use disorders.

BACKGROUND

[0002] Sedative, hypnotics, or anxiolytic use disorder is a misuse of sedative, hypnotics, or anxiolytic substances. Sedative, hypnotics, or anxiolytics can be obtained legally and illegally. The addiction of these substances often occurs together with other drugs of abuse. This usually reflects an effort to counteract the effects of those other drugs. For example, people may abuse benzodiazepines to help them "come down" from the high of cocaine. Sedative, hypnotics, or anxiolytic dependence causes withdrawal symptoms, which makes it difficult to stop taking them, consequently developing an addiction. Commonly abused sedative, hypnotics, or anxiolytic include Xanax®, Valium®, Ativan®, Ambien®, sleep aids, barbiturates, etc.

[0003] Gamma-aminobutyric acid (GABA) is the key inhibitory neurotransmitter involved in anxiety and in the anxiolytic action of psychotropic drugs used to treat anxiety disorders. The long-term pharmacodynamic interaction of benzodiazepines with the GABA receptor is thought to be extremely complex. After long-term benzodiazepine use, the receptor effects caused by the agonist are attenuated. This down-regulation of receptor response is not due to decrease in receptor number or to decreased affinity of the receptor for GABA. These changes are potential mechanisms of tolerance, withdrawal, and dependence. The abrupt cessation of benzodiazepines, as in the case of a patient discontinuing a benzodiazepine after long-term use, is thought to result in the classically described acute withdrawal symptoms as the inhibitory effect of benzodiazepines is removed, thus leading to a relative excitatory state. There remains a need for treating sedative, hypnotics, or anxiolytic use disorders. BRIEF SUMMARY

DETAILED DESCRIPTION

Definitions

[0009] It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.

[0010] As used herein, 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. The term "includes" is defined inclusively, such that "includes A or B" means including A, B, or A and B.

[0011] As used herein, the term "about" is used herein to mean approximately, in the region of, roughly, or around. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term "about" or "approximately" is used herein to modify a numerical value above and below the stated value by a variance of 20%.

As used herein, the phrase “ranges from between about” and “ranges from between” includes both lower and upper numerical end point values and all numerical values between the recited lower and upper numerical values.

[0012] As used herein in the specification and in the claims, "or" should be understood to have the same meaning as "and/or" as defined above. For example, when separating items in a list, "or" or "and/or" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as "only one of or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of a number or list of elements. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e. "one or the other but not both") when preceded by terms of exclusivity, such as "either," "one of," "only one of or "exactly one of." "Consisting essentially of," when used in the claims, shall have its ordinary meaning as used in the field of patent law.

[0013] The terms "comprising," "including," "having," and the like are used interchangeably and have the same meaning. Similarly, "comprises," "includes," "has," and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of "comprising" and is therefore interpreted to be an open term meaning "at least the following," and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, "a device having components a, b, and c" means that the device includes at least components a, b and c. Similarly, the phrase: "a method involving steps a, b, and c" means that the method includes at least steps a, b, and c. Moreover, while the steps and processes may be outlined herein in a particular order, the skilled artisan will recognize that the ordering steps and processes may vary.

[0014] As used herein in the specification and in the claims, the phrase "at least one," in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B," or, equivalently "at least one of A and/or B") can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc. [0015] As used herein, the term "administering" means providing a composition, formulation, or specific agent to a subject in need of treatment, including those described herein.

[0016] The phrases "pharmaceutically acceptable" or "pharmacologically acceptable" refer to molecular entities and compositions that do not produce adverse, allergic, or other untoward reactions when administered to an animal or a human. As used herein, "pharmaceutically acceptable carrier" includes solvents, buffers, solutions, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like acceptable for use in formulating pharmaceuticals, such as pharmaceuticals suitable for administration to humans. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the expression vectors of the present disclosure, its use in therapeutic compositions is contemplated.

[0017] As used herein, the term "subject" refers to a mammal such as a human, mouse, a horse, a dog, or a primate. Typically, the mammal is a human (homo sapiens). A human subject may be an adult patient or a pediatric patient.

[0018] As used herein, the terms "therapeutically effective dose" or "dose amount" refer to an amount of a composition, or a component of the composition, which is effective to achieve an improvement in a subject or his physiological systems including, but not limited to, improved improvement or elimination of symptoms, delayed onset of a disorder, slower progress of symptoms and other indicators selected as appropriate by those skilled in the art. [0019] As used herein, the terms "treatment," "treating," or "treat," with respect to a specific condition, refer to obtaining a desired pharmacologic and/or physiologic effect. The effect can be prophylactic in terms of completely or partially preventing a disease or symptom thereof and/or can be therapeutic in terms of a partial or complete cure for a disease and/or adverse effect attributable to the disease. "Treatment," as used herein, covers any treatment of a disease in a subject, particularly in a human, and includes: (a) preventing the disease from occurring in a subject which may be predisposed to the disease but has not yet been diagnosed as having it; (b) inhibiting the disease, i.e., arresting its development; and (c) relieving the disease, i.e., causing regression of the disease and/or relieving one or more disease symptoms. "Treatment" can also encompass delivery of an agent or administration of a therapy in order to provide for a pharmacologic effect, even in the absence of a disease or condition. The term "treatment" is used in some embodiments to refer to administration of a compound of the present disclosure to mitigate a disease or a disorder in a host, preferably in a mammalian subject, more preferably in humans. Thus, the term "treatment" can include includes: preventing a disorder from occurring in a host, particularly when the host is predisposed to acquiring the disease but has not yet been diagnosed with the disease; inhibiting the disorder; and/or alleviating or reversing the disorder. Insofar as the methods of the present disclosure are directed to preventing disorders, it is understood that the term "prevent" does not require that the disease state be completely thwarted. Rather, as used herein, the term preventing refers to the ability of the skilled artisan to identify a population that is susceptible to disorders, such that administration of the compounds of the present disclosure can occur prior to onset of a disease. The term does not mean that the disease state must be completely avoided.

Cyclodextrins are cyclic oligosaccharides composed of cyclic a-(l— >4) linked D- glucopyranose units. Cyclodextrins with six to eight units have been named a-, [3- and y- cyclodextrin, respectively. The number of units determines the size of the cone-shaped cavity which characterizes cyclodextrins and into which drugs may include to form stable complexes. A number of derivatives of a-, [3- and y-cyclodextrin are known in which one or more hydroxyl groups is/are replaced with ether groups or other radicals. These compounds are thus known complexing agents and have been previously used in the pharmaceutical field to form inclusion complexes with water-insoluble drugs and to thus solubilize them in aqueous media.

[0057] The cyclodextrins within the scope of the present disclosure include the natural cyclodextrins a, [3, and y-cyclodextrin, and derivatives thereof, in particular, derivatives wherein one or more of the hydroxy groups are substituted, for example, by alkyl, hydroxyalkyl, carboxyalkyl, alkylcarbonyl, carboxyalkoxyalkyl, alkylcarbonyloxyalkyl, alkoxy carbonylalkyl or hydroxy-(mono or polyalkoxy)alkyl groups; and wherein each alkyl or alkylene moiety preferably contains up to six carbons. Substituted cyclodextrins can generally be obtained in varying degrees of substitution, for example, from 1 to 14, preferably from 4 to 7; the degree of substitution is the approximate average number of substituent groups on the cyclodextrin molecule, for example, the approximate number of hydroxypropyl groups in the case of the hydroxypropyl-[3-cyclodextrin molecule, and all such variations are within the ambit of this present disclosure . Substituted cyclodextrins which can be used in the present disclosure include poly ethers, for example, as described in U.S. Pat. No. 3,459,731.

[0058] Further examples of substituted cyclodextrins include ethers wherein the hydrogen of one or more cyclodextrin hydroxy groups is replaced by Ci-6 alkyl, hydroxy-Ci- 6 alkyl, carboxy-Ci-6 alkyl or Ci-6 alkyloxy carbonyl-Ci-6 alkyl groups or mixed ethers thereof. In particular, such substituted cyclodextrins are ethers wherein the hydrogen of one or more cyclodextrin hydroxy groups is replaced by C1-3 alkyl, hydroxy-C2-4 alkyl or carboxy-Ci-2 alkyl or more particularly by methyl, ethyl, hydroxyethyl, hydroxypropyl, hydroxybutyl, carboxymethyl or carboxyethyl. The term "C1-6 alkyl" is meant to include straight and branched saturated hydrocarbon radicals, having from 1 to 6 carbon atoms such as methyl, ethyl, 1 -methylethyl, 1,1 -dimethylethyl, propyl, 2-methylpropyl, butyl, pentyl, hexyl and the like.

[0087] In some embodiments, the DHH-B formulations may include an emulsifier. The emulsifier may be any known to those of ordinary skill in the art. In some embodiments, the emulsifier is a block copolymer containing a polyoxyethylene block, i.e. a block made up of repeating ethylene oxide moieties. A suitable emulsifier of this type is Poloxamer, i.e. a poly oxyethylene-poly oxypropylene block copolymer, such as Poloxamer 188. See the Handbook of Pharmaceutical Excipients, p. 352,2nd Edn. Pharmaceutical Press, London, 1994, Eds, Wade and Weller.

[0088] In some embodiments, the emulsifier is a phospho emulsifier. This can be any pharmaceutically acceptable material derived from soybeans or eggs, e.g. soy or egg lecithins. Egg lecithins, such as the material provided by Lipoid (Germany) known as Lipoid E80, which contains both phosphatidylcholine and phosphatidyl ethanoline, are preferred, although other phospholipid materials could be used including phospholipid- polyethylene glycol (PEG) conjugates (PEGylated phospholipids) that have been described for use in liposome systems, e. g. by Litzinger et al, Biochem Biophys Acta, 1190 (1994) 99-107.

[0090] In some embodiments, the emulsifier may comprise a polysaccharide. The polysaccharide may be linear or branched, sulfated or unsulfated. In some embodiments, the composition comprises one or more linear sulfated polysaccharide known as "carrageenan". [0091] In some embodiments, the emulsifier is a carrageenan, for example one or more of a lambda-carrageenan, kappa-carrageenan, iota-carrageenan and any mixture of the carrageenans. The carrageenans are a family of linear sulfated polysaccharides that are extracted from edible seaweed and widely used in the food industry. The USPNF 23 describes carrageenan as hydrocolloid obtained by extraction and purification with water or aqueous alkali from few members of the class Rhodophyceae (red seaweed). It consists mainly of potassium, sodium, calcium magnesium and ammonium sulfate esters of galactose and 3,6-anhydrogalactose copolymers. These hexoses are alternatively linked at the a-1,3 and P-1,4 sites in the polymer.

[0092] Carrageenans are divided into three families according to the position of sulfate groups and the presence of anhydrogalactose. Lambda-carrageenan (Z-carrageenan) is a nongelling polymer containing about 35% ester sulfate by weight and no 3,6- anhydrogalactose. lota-carrageenan (t-carrageenan) is a gelling polymer containing about 32% ester sulfate by weight and approximately 30% 3,6-anhydrogalactose. Kappa carrageenan (K-carrageenan) is a strongly gelling polymer which has a helical tertiary structure that allows gelling. It contains 25% ester sulfate by weight and approximately 34% 3,6-anhydrogalactose. Among the three carrageenans, Z-carrageenan is the only nongelling polymer.

[0093] In some embodiments, the emulsifier is selected from the group consisting of a monoglyceride, a diglyceride, and any mixture thereof. The term "monoglyceride" refers to a molecule with one glycerol moiety covalently bonded to a fatty acid chain via an ester bond. The term "diglyceride" refers to a molecule with one glycerol moiety covalently bonded to two fatty acid chains via ester bonds. In some embodiments, the emulsifier includes a mixture of monoglycerides and diglycerides. In some embodiments, the emulsifier includes a mixture of monoglycerides and diglycerides and a carrageenan.

In some embodiments, triglycerides include vegetable oils, fish oils, animal fats, hydrogenated vegetable oils, partially hydrogenated vegetable oils, medium and long-chain triglycerides, and structured triglycerides. In some embodiments, the emulsifier may be an oil, including vegetable oils such as soybean oil, olive oil, cotton seed oil, peanut oil, sesame oil and castor oil, with sesame oil and castor oil being preferred.

[0095] In some embodiments, the emulsifier is a fatty acid ester of polyoxyethylene sorbitan (e.g. Polysorbate® 80, Polysorbate® 20, etc.).

[0096] In some embodiments, the DHH-B formulations may be provided in the form of dispersible powders and/or granules, such as those suitable for the preparation of an aqueous suspension.

Suitable dispersing or wetting agents and suspending agents are exemplified by those already described herein. Additional excipients, for example, those sweetening, flavoring and coloring agents described above may also be present, including each of those described herein. Coloring agents can be used to color code compositions, for example, to indicate the type and dosage of the therapeutic agent therein. Coloring agents can also be used to differentiate the varied fractions of multiparticulates comprised in a unit dosage form such as a capsule. Suitable coloring agents include, without limitation, one or more natural and/or artificial colorants such as FD&C coloring agents, natural juice concentrates, pigments such as titanium oxide, silicon dioxide, iron oxides, zinc oxide, and the like.

[0097] The DHH-B formulations of the present disclosure may also be in the form of oil-in-water emulsions.

[0120] An example of an injectable formulation is provided below:

[0121] 1 Liter Formulation:

[0122] 25,000 mg/L = 25 mg/ml DHH-B

[0123] Solid and Liquid Food Products

[0124] An effective amount of any one of the DHH-B formulations may be added to an arbitrary food or beverage product or functional food that does not substantially contain a dihydrohonokiol or a derivative or analog. Thus, of any one of the DHH-B formulations of the present disclosure may be prepared in the form of a food or beverage product or functional food. Examples of food or beverage products and functional foods include, but are not limited to, confectioneries, retort pouch food, juice, teas, and dairy products. In addition, sweetening agents, seasonings, emulsifiers, suspending agents, antiseptics, or the like can be added to the food or beverage product or functional food, according to need. Further, the antianxiety composition of the present disclosure can be used as a food additive. [0125] A food product, dietary composition, or supplement according to the present disclosure is any ingestible preparation that contains the natural product compositions of the present disclosure mixed with a food product or dietary supplement composition. The food product can be dried, cooked, boiled, lyophilized or baked. A food composition or food product can comprise a bakery product, including but not limited to bread, pastries, brownies, cakes, pies, donuts, crackers, and muffins. A food composition or food product can comprise a dairy product, including but not limited to milk, fermented milk, curd, whey, yogurt, cream, cheese, butter, clarified butter, ghee, and ice cream. A food composition or food product can comprise a nut butter or seed butter, including but not limited to peanut butter, almond butter, cashew butter, hazelnut butter, macadamia nut butter, pecan butter, pistachio butter, walnut butter, pumpkin seed butter, sesame seed butter, soybean butter, and sunflower seed butter. A food composition or food product can comprise an oil (e.g., a cooking oil), including but not limited to olive oil, coconut oil, vegetable oil, canola oil, com oil, peanut oil, sunflower seed oil, almond oil, avocado oil, rice bran oil, cottonseed oil, flaxseed oil, linseed oil, grape seed oil, hemp oil, mustard oil, macadamia oil, palm oil, tea seed oil, walnut oil, margarine, lard, butter, clarified butter, ghee, or tallow. A food composition or food product can comprise sports food products such as energy gels, sports drinks, energy powders, energy bars, energy shots, protein powders, and protein drinks (e.g., protein shakes). A food composition or food product can comprise a beverage, including but not limited to water, electrolyte drinks, soda, coconut water, tea (e.g., Jun tea, black tea, green tea, white tea, herbal tea), coffee, a soft drink, an alcoholic beverage (e.g., cocktail, liquor, spirits, beer, wine, malt beverage), water, juice (e.g., apple juice, orange juice, tomato juice, vegetable juice, cranberry juice), a sports drink, electrolyte-enriched water, vitamin-enhanced water, milk (e.g., dairy-based milk, coconut milk, almond milk, soy milk, hemp milk, rice milk, oat milk, cashew milk, hazelnut milk), and yogurt.

[0126] A food composition or food product may include the natural product composition disclosed herein within a gelatin-based product (e.g. Jell-O®) or gelatin-based desert.

Suitable examples of gelling agents include carrageenans, agar, sodium alginate, gellan gum, xanthan gum, sodium carboxymethyl cellulose, guar gum, soybean protein, and crystalline cellulose. The amount of the gelling agent contained within the food composition or food product is not limited provided that the effect of the present disclosure is obtained. The proportion of the gelling agent in the food composition is, for example, about 0.5 to about 3 by total weight of the food composition or food product. Without wishing to be bound by any particular theory, it is believed that the amount of the gelling agent contained affects the hardness in mastication. If the amount of gelling agent is less than about 0.5 by total weight of the food composition or food product, the food composition or food product tends to become overly soft and cannot achieve a hardness suitable for mastication. If, on the other hand, the amount is more than about 3 by total weight of the food composition or food product, the food composition or food products tends to fail to achieve a hardness at which chewing can be performed, even if the number of mastications is increased.

[0153] A protocol for the treatment of anxiolytic use disorder may involve the reduction of dose over time of the sedative, hypnotic, or anxiolytic in conjunction with an escalating dose of DHH-B in a manner such that the patient does not experience withdrawal symptoms associated with the reduction of medication that is associated with anxiolytic use disorder. This process may involve complete substitution therapy with DHH-B. In studies, DHH-B has been shown to not create habit-forming dependencies, that lead to withdrawal symptoms upon cessation of treatment. These protocols may involve a de-escalation in the dose of sedative, hypnotic, or anxiolytic in simultaneous dose escalation of DHH-B. In other embodiments, the treatment protocol may involve the addition of DHH-B at a point in the de- escalation of the dose of the use disorder substance at a point when the patient experiences withdrawal symptoms.

[0156] EXAMPLES

[0157] Example 1 - Dihdrohonkiol-B - Cyclodextrin Complexation Process:

[0158] Into a 250 ml beaker was added 90 ml deionized water. The beaker was placed on a stirring plate and heated to 70° C. A magnetic stir bar was placed into the beaker and set to a speed that created a vortex in the water. Into the water was added 45 g of Hydroxypropyl-beta cyclodextrin (HPBCD). The cyclodextrin rapidly went into solution. Into the solution of water, 5 g of Dihydrohonokiol-B that was slowly added.

[0159] Example 2 - Water-Soluble Tablet Formulations

[0160] For the manufacturing of a water-soluble tablet ingredient, the solution was transferred to a vacuum oven and heat applied along with vacuum overnight to remove the water from the dihydrohonokiol cyclodextrin complex. This material has been used in beverages, tablets, and Oral Dissolving Tablets (ODT).
