Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to the formulation of drugs. More specifically, the present invention relates to an immediate release formulation for a pharmaceutical formulation of d-lysergic acid diethylamide (LSD).

2. Background Art

Oral solution formulations are convenient for studies in a small number of sites and with a limited number of patients, mainly early phase development studies, but may not be suitable for later phase development studies run in many centers and across wide geographies nor for commercialization due to challenges in product stability and supply chain, such as the potential requirement for cold chain storage.

Solid oral formulations as tablets or capsules are more common in later phase clinical development and commercially due to advantages in production, supply chain, and patient convenience. Solid oral formulations can be immediate release, dissolving instantaneously in the mouth or stomach, or extended release in which the drug release is prolonged over time.

Orally disintegrating tablets (ODTs) are another solid dosage form which is formulated with the aim of increasing the dissolution rate of a pharmaceutical product and promoting pre-gastric absorption. In order to achieve rapid disintegration rates, the ODT formulation must provide high porosity, low density, and a low hardness (Berthoumieu et al., 2010; Bandari et al., 2008). This dosage form can be chosen to modify absorption or for patient populations that have difficulty in swallowing (Lindgren et al., 1993), and is also suitable for use in geriatric and pediatric patients, or for those who suffer from conditions such as dysphagia (Sastry et al., 2000).

LSD is derived from its German name LysergSäureDiethylamid (Lysergic acid diethylamide). Lysergide belongs to a family of indole alkylamines that includes numerous substituted tryptamines such as psilocin (the active moiety of psilocybin) and N,N-dimethyltryptamine (DMT). The IUPAC name for LSD is 9,10-didehydro-N,N-diethyl-6-methylergoline-8β-carboxamide.

LSD can be used to assist psychotherapy for many indications including anxiety, depression, addiction, personality disorder, and others and can also be used to treat other disorders such as cluster headache, migraine, and others (Passie et al., 2008; Hintzen et al., 2010; Nichols, 2016; Liechti, 2017). Effects of LSD can include altered thoughts, feelings, awareness of surroundings, dilated pupils, increased blood pressure, and increased body temperature. Therapeutic use of LSD shows promising results for treating various neurological and behavioral disorders. However, due to its potency there can be challenges in developing and manufacturing solid oral formulations of LSD that meet pharmaceutically acceptable limits for content uniformity and chemical stability.

Clinical studies with LSD have focused on oral solution drug product forms. There has been little to no formulation development work with LSD. Oral solutions were used historically and almost all the old studies and anecdotal data are with oral solutions or impregnated papers/cartons.

There is a need for an LSD dosage form and drug product that is both commercially attractive to a broad patient population and meets regulatory / quality expectations for suitability and robustness. A commercially viable solid oral, immediate release pharmaceutical formulation of d-Lysergic Acid Diethylamide (LSD), as a free base or in a salt form, does not currently exist as a marketed product or reported in literature. With the expected therapeutic dose of LSD to be in the 10′s to 100′s of micrograms, challenges exist for achieving acceptable drug content uniformity and chemical stability. Furthermore, previous studies have shown LSD in oral solution is not stable at room temperature (Holze et al 2019).

In addition to achieving a uniform and stable immediate release drug product formulation, the final drug product should be in a form that is easily administered to a broad range of patient populations, including, but not limited to the elderly, pediatrics, and patients with a condition that may limit their ability to swallow.

SUMMARY OF THE INVENTION

The present invention provides a solid oral immediate release formulation of LSD, including LSD formulations intended for a capsule, tablet, or orally disintegrating tablet dosage form.

The present invention further provides a method of making a solid oral immediate release formulation of LSD using processes such as granulation and blending that are uniform, chemically stable, and dissolve rapidly.

The present invention also provides for a method of treating an individual by administering a solid oral immediate release formulation of LSD.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides for a solid oral formulation of LSD in a quick or immediate release dosage form such as a capsule, tablet, or orally disintegrating tablet. The term “quick release tablet” is a mechanism that (similar to immediate-release dosage) delivers a drug immediately in contrast with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release (ER, XR, XL) dosage) or to a specific target in the body (targeted-release dosage). Preferably, it refers to minimal time dependent release in oral dose formulations. The present invention provides a composition, preferably including LSD as its active, or one of its active ingredients, which dissolves relatively quickly once orally ingested. This provides an easy to administer yet anticipated to be effective and efficacious therapeutic effect.

The LSD can be in a free base form or a salt form as a crystalline or non-crystalline solid. The salt can be, but is not limited to, hydrochloride, hydrobromide, maleate, tartrate (including D-tartrate and meso-tartrate), citrate, phosphate, fumarate, sulfate, mesylate, acetate, oxalate, benzoate, benzensulfonate, xinafoate, 1,5-Napthalene disulfonate, ascorbate, and naphthalene-2-sulfonate. The dose of LSD can preferably be 0.01-1 mg (10-1000 µg). However, dosing can be adjusted depending on indication, age, weight, and other factors affecting the pharmacology, physiology, and drug/drug interactions in a given patient.

Solid oral formulations typically contain secondary ingredient components known as excipients which can include but are not limited to fillers/bulking agents, binders, absorbents, disintegrants, glidants, lubricants, pH modifiers/buffers, preservatives, antioxidants, permeation enhancers, coloring agents, and sweeteners / flavoring agents. Examples of each are listed below and some common excipients serve more than one function.

Examples of fillers used in solid oral formulations include lactose (including anhydrous), mannitol, dicalcium phosphate, calcium sulfate, starch (starch as used herein can include dry or pre-gelled), cellulose (including microcrystalline cellulose), kaolin, sodium chloride, sorbitol, trehalose, sucrose, etc.

Binders, which are polymeric, natural, or synthetic materials that impart cohesive qualities to powdered materials, can also be included. Binders must be non-toxic and must have a good compatibility profile. Materials commonly used as binders include acacia gum, methylcellulose, hydroxypropyl methylcellulose, hydroxypropyl cellulose, tragacanth, polyvinyl pyrrolidone (PVP), starch, etc. Microcrystalline cellulose is also considered a dry binder.

Excipients such as starch, colloidal or mesoporous silicon dioxide (i.e., silica), sodium starch glycolate, and microcrystalline cellulose can act as solvent absorbents or disintegrants by absorbing solvents such as water while increasing the formulation wettability. Some of these excipients can be preferred for either absorbent of disintegrant properties but can also include the other property. For example, partially pre-gelled starch (e.g., Starch 1500) is often used as a disintegrant, but is also used as an absorbent to scavenge moisture to ‘hide’ the moisture from drugs that are sensitive to it. When Starch 1500 is used as an absorbent in moisture activated dry granulation (MADG) it loses some of its disintegrant capability, but if it is added after the absorbent stage it can function as a disintegrant. Colloidal (or mesoporous) silicon dioxide can be an excellent absorbent but can be a weak disintegrant. Sodium starch glycolate can be an excellent disintegrant. Microcrystalline cellulose is an excellent absorbent and can have disintegrant properties. Croscarmellose sodium, crospovidone, sodium starch glycolate (which are disintegrants) and starch swell in the presence of aqueous fluids, thereby facilitating tablet disintegration due to the increase in the internal pressure within the tablet matrix.

Glidants enhance the flowability of a formulation. Typical glidants include magnesium stearate, colloidal silicon dioxide, etc.

The hydrophobic stearic acid and stearic acid salts e.g., magnesium stearate and sodium stearyl fumarate, are the most widely used lubricants in oral drug formulations. They are typically added at concentrations less than 2% w/w in order to minimize any deleterious effect on formulation matrix disintegration or dissolution. Other examples of lubricants used include polyethylene glycol (PEG), polyoxyethylene stearates, lauryl sulphate salts, talc, glyceryl behenate, glyceryl palmitostearate, calcium stearate, hydrogenated vegetable oils etc.

Buffer is added to target the formulation to a specific pH. Currently, three buffers, citrate, phosphate, and acetate, make up the majority of buffers used in pharmaceuticals approved by the FDA, but less precedented excipients are certainly available to use in commercial dosage forms. The pH of a formulation alternatively can be adjusted with unbuffered acid (i.e., hydrochloric acid) or unbuffered base (i.e., sodium hydroxide).

Antioxidants can be added to the formulation in order to minimize degradation due to oxidative stress. The term oxidation can be defined as the incorporation of oxygen into the structure of a drug, or as the process of converting one chemical substance into another derivative bearing a smaller number of electrons. Examples of such antioxidants are ascorbic acid, citric acid, butylatedhydroxy anisole (BHA), and butylated hydroxytoluene (BHT).

Many drugs are sensitive to light and therefore their formulated products can degrade during manufacturing, storage, and administration. The photostability of a drug substance can be defined as the response of the drug or drug product to the exposure to solar, UV, and visible light in the solid, semisolid, or liquid state that leads to a physical or chemical change. Undue light exposure can result in potency loss, altered efficacy, and adverse biological effects. Various additives or encapsulation methods and compositions can be used to protect the active product from light in order to minimize any degradation due to light exposure (i.e., photostabilization agents). For example, liposomes are microscopic and submicroscopic phospholipid vesicles with a bilayered membrane structure. Photostabilization of the drug substance by entrapment into liposomes is one such way to improve their photostability.

Photo degradation can also occur in combination with oxygen exposure, resulting in photo-oxidation degradation. Some of the commonly used antioxidants to protect against photo-oxidation are ascorbic acid, α-tocopherol, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), L-histidine, propyl gallate, and sulfur compounds. Ascorbic acid, α-tocopherol, β-carotene, and BHT act as free radical scavengers and singlet oxygen quenchers and thus inhibit the photosensitization reactions. If a drug substance acts as a photosensitizer and initiates a chain reaction in the drug product, some of the excipients can be oxidized, while the drug can be protected from photodegradation.

The formulation can also contain permeability enhancers to increase the extent and/or rate of absorption. Examples of such enhancers are sulphoxides (such as dimethyl sulphoxide, DMSO), azones (e.g., laurocapram), pyrrolidones (for example 2-pyrrolidone, 2P), alcohols and alkanols (ethanol, or decanol), glycols (for example propylene glycol, PG, a common excipient in topically applied dosage forms), surfactants (also common in dosage forms) and terpenes.

Coloring agents, sweeteners, and flavoring agents can also be added to solid oral formulations in order to improve patient recognition and acceptability.

Immediate release formulations produced by granulation can contain but are not limited to the solid oral formulation fillers/bulking agents, binders, absorbents, disintegrants, glidants, and lubricants as described above as well as buffers, antioxidants, absorption enhancers, and coloring and flavoring agents. One such granulation process is high shear granulation whereby powders (active, dry binders, fillers, etc. such as LSD, binders, and fillers) are charged to a closed container which contains mixing/blending components such as an impeller and chopper. In high shear wet granulation, hereafter referred to as wet granulation, the powders are wetted with a binder solution/suspension while mixing allowing for particle cohesion and granule growth. Additional excipients (filler, glidants, disintegrants, lubricants, etc.) can be added and mixed with the granules after the binder solution/suspension addition. Depending on the concentration of the active, it is typically added either as a dry ingredient (higher concentrations of active ingredient typically greater than 1-10% by weight) prior to the binder solution/suspension addition or contained within the binder solution/suspension (lower concentrations of active ingredient typically less than 1-10% by weight) to ensure uniformity. In wet granulation when active is added in solution or suspension the liquid solvent is removed by active drying. Alternatively, with a process called moisture activated dry granulation (MADG) in EXAMPLE 1, the liquid (typically water) content is reduced and taken up by absorbents added to the formulation rather than introducing an active drying step.

Dry blending of crystalline API, either micronized or not micronized, is an alternative solid oral formulation approach to granulation, further described in EXAMPLE 2. Dry blending can employ similar mixing/blending equipment as granulation or with lower shear mixing and can use similar excipient classes, minimally with a filler. Dry blending formulations can be further processed into tablets including orally disintegrating tablets through direct compression or encapsulated. When forming for direct compression, the composition can also include any of the binders, disintegrants, glidants, and lubricants described above as needed for processing.

The compound of the present invention is administered and dosed considering the clinical condition of the individual patient, the site and method of administration, scheduling of administration, patient age, sex, body weight and other factors known to medical practitioners. The pharmaceutically “effective amount” for purposes herein is thus determined by such considerations as are known in the art. The amount must be effective to achieve improvement including but not limited to improved survival rate or more rapid recovery, or improvement or elimination of symptoms and other indicators as are selected as appropriate measures by those skilled in the art.

In the method of the present invention, the compound of the present invention can be administered in various ways. It should be noted that it can be administered as the compound and can be administered alone or as an active ingredient in combination with pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles. The patient being treated is a warm-blooded animal and, in particular, mammals including humans. The pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles generally refer to inert, non-toxic solid or liquid fillers, diluents or encapsulating material not reacting with the active ingredients of the invention.

The doses can be single doses or multiple doses over a period of several days. The treatment generally has a length proportional to the length of the disease process and drug effectiveness and the patient species being treated.

Absorption of the active drug can be targeted. Drug absorption is determined by the drug’s physicochemical properties, formulation, and route of administration. Dosage forms (e.g., tablets, capsules, solutions), consisting of the drug plus other ingredients, are formulated to be given by various routes (e.g., oral, buccal, sublingual, rectal, parenteral, topical, inhalational). Regardless of the route of administration, drugs must be in solution to be absorbed. Thus, solid forms (e.g., tablets, capsules) must be able to disintegrate and deaggregate. Solid oral tablets and capsule formulations typically have gastric absorption, whereas an ODT formulation can be formulated to target pre-gastric or buccal absorption which can further enhance bioavailability.

The present invention provides for a method of making a solid oral immediate release formulation of LSD, as a free base or in a salt form, by a step chosen from 1) granulating with excipients such as fillers, absorbents, binders, disintegrants, glidants, and/or lubricants to encapsulate or form a tablet; or 2) blending with excipients such as fillers, disintegrants, dry binders, glidants, and/or lubricants for direct compression into tablets, including ODTs, or encapsulation. Each approach considers the challenges associated with formulating a low dose product while maintaining content uniformity and chemical integrity of LSD.

The present invention provides for a method of treating an individual, by administering a solid oral immediate release formulation of LSD and treating the individual.

The condition or disease being treated can include, but is not limited to, anxiety disorders (including anxiety in advanced stage illness e.g. cancer, as well as generalized anxiety disorder), depression (including postpartum depression, major depressive disorder and treatment-resistant depression), headache disorder (including cluster headaches and migraine headache), obsessive compulsive disorder (OCD), personality disorders (including conduct disorder), stress disorders (including adjustment disorders and post-traumatic stress disorder), drug disorders (including alcohol dependence or withdrawal, nicotine dependence or withdrawal, opioid dependence or withdrawal, cocaine dependence or withdrawal, methamphetamine dependence or withdrawal), other addictions (including gambling disorder, eating disorder, and body dysmorphic disorder), pain, neurodegenerative disorders (such as dementia, Alzheimer’s Disease, Parkinson’s Disease), autism spectrum disorder, eating disorders, or neurological disorders (such as stroke).

The invention is further described in detail by reference to the following experimental examples. These examples are provided for the purpose of illustration only and are not intended to be limiting unless otherwise specified. Thus, the invention should in no way be construed as being limited to the following examples, but rather, should be construed to encompass any and all variations which become evident as a result of the teaching provided herein.

EXAMPLE 1: Granulating d-LSD D-tartrate with Excipients

A single pot granulation process called moisture activated dry granulation (MADG) was used for formulating low dose LSD in order to achieve suitable content uniformity and avoid a separate active drying step that would typically be performed with wet granulation. For MADG, the method of making LSD formulations includes: 1) Creating a granulation liquid stock solution of LSD, water (or other suitable solvent), and solubility aids if needed; 2) Blending a filler (i.e. mannitol) and binder (i.e. hydroxypropyl methylcellulose); 3) Spraying the granulation liquid onto the dry mixture and blending to form an agglomeration; 4) Adding a moisture absorbent (i.e. starch) and blending; and finally 5) Adding additional functional excipients such as disintegrants, glidants, and lubricants and blending to form the final granulation powder. In an optimized process there are no lumps in the final granule, so sieving is not required. The final granulation can be encapsulated or formed into tablets.

TABLE 1 shows 25 µg LSD (equivalent to 36.6 µg of d-LSD D-tartrate) formulations developed with microcrystalline cellulose and starch as absorbents in the MADG process. These formulations were encapsulated, placed on stability at 25° C., and tested for total impurities. TABLE 2 shows total impurity results for the microcrystalline cellulose formulation and TABLE 3 shows total impurity results for the starch formulation. In addition, FIG. 3 shows the dissolution profile for the starch containing formulation, which demonstrates immediate release of LSD or complete dissolution within 15 minutes.

3 Month @ 25° C.  1.8
6 Month @ 25° C.  1.7

Additional granulation formulations of d-LSD D-tartrate using moisture-activated dry granulation and pregelled starch as the absorbent were made but excluding a lubricant. The composition is comparable to the Starch Formulation in TABLE 1 without sodium stearyl fumarate.

FIG. 2 shows content uniformity of the pregelled starch formulation without a lubricant. The process capability based on these results indicates that less than 0.5 parts-per-million (ppm) capsules would be outside the 85%-115% label claim range. The data provides evidence that the uniformity of the final blend was satisfactory.

TABLE 4 shows the chemical stability data for the pregelled starch formulation without a lubricant at 25° C.

Time Point       Total Impurity (% Area)
Initial.         0.2
1 Month @ 25° C. 0.3
3 Month @ 25° C. 0.5

Together these data show that moisture-activated dry granulation can produce a pharmaceutically acceptable uniform, stable, and immediate release formulation of LSD.

EXAMPLE 2: Dry Blending d-LSD D-tartrate Drug Crystals with Excipients

The method for making dry blend formulations of LSD in a single pot includes adding a minimum filler / carrier excipients, such as mannitol, lactose, and microcrystalline cellulose and d-LSD D-tartrate to a mixing vessel and blending until the drug is uniformly dispersed. The order of addition for the components, or parts of the components, can be adjusted as needed.

The chemical purity of d-LSD D-tartrate salt (FIG. 4) when blended as a solid drug crystal with solid excipient in an approximate ratio of 1:100 was assessed over a prolonged period (3 and 6 weeks) at 40° C. from the bulk formulation. TABLE 5 shows chromatographic purity results of the three dry blend d-LSD D-tartrate formulations at 40° C. demonstrating minimal change in chemical purity for each of the filler / carrier excipients.

Chromatographic Purity results for d-LSD D-tartrate drug crystals blended with various filler excipients, stored at 40° C., and analyzed for chemical stability at T=0, T=3 weeks and T=6 weeks

The results show that d-LSD D-tartrate drug crystals blended with lactose, mannitol, and microcrystalline cellulose are stable. FIG. 4 shows the % iso-LSD, a known LSD degradation product, versus condition and excipient.
