TECHNOLOGICAL FIELD

The invention pertains to pharmaceutical compositions comprising cannabinoids and Cannabis-based formulations, and further to methods using thereof for the treatment of inflammatory conditions of the gastrointestinal (GI) tract, specifically Inflammatory Bowel Disease (IBD), including Crohn's Disease and Ulcerative Colitis.

BACKGROUND

Medicinal value of Cannabis is well documented in literature. Cannabinoids, the active ingredients of Cannabis, are found in the resin-producing pistillate inflorescences of female Cannabis plants. Various types of Cannabis, such as Cannabis Sativa and Cannabis Indica, may contain 60 to 80 different kinds of cannabinoids, notable examples of which are tetrahydrocannabinol (THC) and cannabidiol (CBD). These two cannabinoids have been related to many distinct pharmacological effects, including analgesic, antiemetic, antioxidative, neuroprotective, and anti-inflammatory activities in various normal and abnormal cells and tissues. The discovery of the endogenous cannabinoid system with specific receptors and ligands in the brain, and in peripheral tissues has led to understanding that the endocannabinoid system represents a previously unrecognized ubiquitous homeostatic network. At least two molecular receptor proteins (CB1 and CB2) and two endogenous cannabinoids (anandamide and 2-acylglycerol) have been identified in numerous body tissues, including the neural and immune systems. It now appears that the endocannabinoid system evolved with our species and is intricately involved in normal human physiology, specifically in movement control, pain, appetite, memory, immunity and inflammation, among others. This explains the tremendous potential of exogenous cannabinoids and Cannabis-based medicines for the treatment of various human disorders.

A number of oral formulations of cannabinoids are commercially available today by prescription for specific clinical indications. Marinol capsules containing dronabinol, a synthetic A ⁹ -THC, in sesame oil were approved in various countries for use as an antiemetic in patients subjected to cancer chemotherapy, and for appetite stimulation in AIDS patients suffering from wasting syndrome. Cesamet capsules comporising nabilone, a synthetic THC analog, were recently approved as a Marinol substitute. Namisol tablets containing pure THC, Arvisol tablets containing CBD and Sativex (nabiximols) an oral spray containing THC and CBD, are more recent Cannabis-based formulations approved for a number of indications including Alzheimer's disease, chronic neural pain, and multiple sclerosis.

The instant invention applies to a group of inflammatory conditions collectively referred to as Inflammatory Bowel Disease (IBD), affecting the gastrointestinal (GI) tract and emerging, most likely, due to an autoimmunity. The two major types of IBD are ulcerative colitis and Crohn's disease. Ulcerative colitis involves predominantly the colon or large intestine, and Crohn's disease - any part of the GI tract, most commonly the small intestine or colon, or both. The main symptoms of ulcerative colitis and Crohn's disease are similar, including pain, swelling or cramping, recurring or bloody diarrhea, weight loss and extreme tiredness. IBD is usually diagnosed in people in their late teens or early 20s, but can affect people of any age. According to CDC, there are about 1-1.3 million people suffering from IBD, in the US alone. The prevalence of Crohn's disease has been estimated at 200 per 100,000 adults, and ulcerative colitis - at 230 per 100,000 adults.

There is currently no definite cure for IBD, the majority of treatments constitute a palliative care. Traditional pharmacological treatments for IBD include, aminosalicylates or corticosteroids to reduce inflammation, and immunosuppressants to reduce activity of the immune system. About 20% of patients with severe symptoms of ulcerative colitis are non- responders and are usually referred to a surgical removal of the inflamed section. In Crohn's disease - about 60-75% of patients may be referred to a surgery.

The inventors have previously noted that certain extracts of Cannabis can be effective for IBD, and for Crohn's disease in particular [1, 2], and that certain strains may have antiinflammatory and nociceptive effects in an animal model of inflammation of non-GI origin [3]. Notwithstanding, these and other human studies using Cannabis were relying to great extent on trial and error, leaving dosing and modes of administration highly individualized.

A Cannabis administered via smoking has the advantage of rapid onset of effect and easy dose titration. However, the guidelines for precise dosing of smoked or vaporized Cannabis have not been yet established. Cannabis may be consumed in baked goods, such as cookies, or drunk as teas or infusions. The absorption of these products, in contrast, is slow and erratic, and the onset of effects lasting much longer compared to smoking. For other dosage forms, e.g., butters, oils, creams and ointments, similarly, no dosing information is currently available and much of the information is anecdotal in nature. Dosing schemes developed on the basis of the known chemistry and pharmacology of Cannabis still suffer from considerable controversy. One prevailing notion, however, is that route of administration is an important determinant of pharmacokinetics of various cannabinoids in Cannabis, particularly the absorption and metabolism.

Despite the general belief that Cannabis is safe and no lethal doses of Cannabis have been reported so far, Cannabis is still considered a hazardous drug. Adverse effects of Cannabis include: cognitive and memory impairments, changes in mood, altered perception, decreased impulse control, particularly during adolescence, occupational hazards, fluctuations of blood pressure, syncope or tachycardia, respiratory insufficiency particularly with smoked Cannabis, increased severity of steatosis in patients with liver or renal disease, pregnancy complications in women, and borderline of infertility in men. There are also significant drug-drug interactions, most notable with sedative-hypnotics and alcohol. Patients with no prior experience with Cannabis are usually cautioned to begin at a very low dose and to stop therapy if unacceptable or undesirable side effects occur. Thus the management of risk/benefits of medicinal Cannabis, and also of the commercial purified oral formulations, is still difficult.

Thus, there is an urgent need for standards to be set that would maximize benefits and minimize risks of using medicinal Cannabis for specific clinical indications., which is all the more critical in view of complexity of cannabinoid pharmacology, inter-individual differences in cannabinoid receptors distribution, density and function, cannabinoid metabolism and bioavailability, and heterogeneity of cannabinoid content in various Cannabis plants. The instant invention is meant to address these issues, specifically in the context of IBD.

GENERAL DESCRIPTION

The instant invention stems from accumulated experience of the inventors with cultivation of novel strains of medical Cannabis and development of controlled methods using thereof for specific clinical indications. In connection with certain embodiments the invention relates to three Cannabis cultivars, or three distinct groups of Cannabis plants, certain members of which were generally described in terms of morphological features and cultivation conditions (see below). These cultivars, including additional members, are now described in relation to surprising clinical properties and clinical uses in the context of IBD. Members of these three cultivars are referred to throughout this document by trade names. The referenced US Plant Patent Applications are herein incorporated by reference, including the applications derived therefrom, i.e., continuation or continuation in part applications.

Thus in certain aspects the invention relates to:

i. A phyto-derived material obtained from a Cannabis strain enriched in THC in an amount ranging from 16 and 24% per weight (w/w), with relatively low CBD, particularly in the resin-producing flowers of female plants. An exemplary member of this group referred to herein as Erez was generally described in the US Plant Patent Application No. 2014/0245494.

ii. A phyto-derived material obtained from a Cannabis strain enriched in CBD and particularly low THC, in amounts ranging from 15 and 16.5% and 0.8 and 3.75% (w/w), respectively. An exemplary member of this group referred to herein as Avidekel was generally described in the US Plant Patent Application No. 2014/0259228.

iii. A phyto-derived material obtained from a Cannabis strain having substantially equal ratio of THC:CBD in an amount ranging from 10 andl3% and 8 and 12.5% (w/w), respectively. An exemplary member of this group referred to herein as Midnight was generally described in the US Plant Patent Application No. 2014/0245495.

It has been presently demonstrated that preparations produced from exemplary members of the above cultivars have specific therapeutic effects in patients with IBD, i.e., Crohn's disease and colitis, revealed by significant improvement of Disease Activity Index (DAI) scores, indices of inflammation according to blood and intestinal disease specific markers, accompanied by a reduction of adverse effects and improvement in general quality of life.

Most notably according to the invention the above therapeutic effects could be enhanced and prolonged by applying certain dosing of administration regimens in the form of mono and combination therapies. Present studies have shown that a phyto-derived material enriched in CBD, for example an oil-based extract of a material derived from Avidekel or other members of this group, is surprisingly effective for prolonged treatment and management of IBD. Such CBD enriched material is particularly effective for the treatment of Crohn's disease. Compositions based on Avidekel and other members of this group are particularly interesting due to scarcity of psychotropic effects and their ensuing suitability to day dosing.

The studies have further demonstrated that a phyto-derived material enriched in THC, for example a material derived from Erez or other members of this group in the form of cigarettes, is also effective for IBD, particularly immediate alleviation of one or more IBD symptoms. Such THC enriched material was particularly beneficial for patients with ulcerative colitis. Erez-based compositions and alike, because of their high THC content, are particularly suitable for night dosing.

An alternative treatment revealed in present studies involved a phyto-derived material containing THC and CBD in equal or substantially equal quantities, exemplified by a material derived from Midnight in the form of cigarettes, for example. This kind of preparation proved to be an effective substitute for THC enriched material (such as Erez), particularly in patients uncompliant with psychotropic effects of THC. Due to their THC:CBD content, Midnight- based compositions and alike are suitable for both, day and night dosing.

Most notably, the presently described study of about 300 patients with IBD, half of which treated for more than 6 months, has demonstrated that in the majority of patients a combination of preparations derived from Avidekel, Erez and/or Midnight proved to be the most effective for immediate as well as prolonged alleviation and treatment, and long term management of IBD.

These findings apply on several levels:

First, in terms of specific cannabinoid compositions comprising certain proportions of THC and CBD to be applied for the treatment of IBD and IBD related conditions;

Second, in terms of specific Cannabis-based compositions used in specific formulations, doses and administration routes to provide immediate relief and long-term management of IBD;

Third, in terms of specific cannabinoid compositions to be applied as specific treatments for Crohn's disease or colitis.

This latter point is particularly surprising in view of difficulties with differential diagnosis of these disorders. The above have laid the basis for the following disclosure of the invention. It should be noted that any of the embodiments and aspects described herein can be used in conjunction with one another, unless otherwise indicated or apparent from the context. Other embodiments will become apparent to those skilled in the art from a review of the ensuing description.

Before describing the invention it should be noted that it is not limited to herein described methods and experimental conditions, as well as the terminology used herein for describing particular embodiments is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, particular methods and materials are now described.

The instant invention generally relates to compositions comprising certain ratios of THC:CBD for use in a method for treating, alleviating or reducing IBD and IBD related conditions, or at least one symptom related to IBD. Such compositions may further comprise carriers, buffers, excipients.

In other words, the invention pertains to a group of intestinal disorders communally referred to as "Inflammatory Bowel Disease" (IBD) or condition, characterized with a prolonged regional enteritis of the GI tract, including the mouth, esophagus, stomach, small intestine and/or large intestine. Notable members of this group are Crohn's disease and ulcerative colitis, and related conditions such as Irritable Bowel Syndrome (IBS). Differential diagnosis of patients that can benefit from the presently described compositions and methods is made by a treating physician on the basis of physical examination, anamnesis and one or more diagnostic tests, including stool and blood tests, a biopsy, and medical imaging using X ray, flexible sigmoidoscopy, colonoscopy, capsule endoscopy, CT or MRI.

Crohn's disease is usually noncontiguous having skipped areas of a normal mucosa. The ulcerations in Crohn disease tend to be linear and often lead to the classic cobblestone appearance of the mucosa. Granulomas are present in 60% of Crohn's disease and almost never present in ulcerative colitis. The inflammation in Crohn's can be transmural, whereas in ulcerative colitis it is confined to the mucosa and submucosa. Crohn's disease may involve the entire GI tract, whereas ulcerative colitis involves only the large bowel. Approximately 90% of patients with Crohn's disease have involvement of the terminal ileum and/or right colon. Pediatric patients are more likely to present with disease limited to the small intestine, although very young children often present with purely colonic disease. A variety of intestinal and extraintestinal manifestations may be observed in conjunction with either Crohn's disease or colitis. Features differentiating these two forms of IBDs are summarized in Table 1.

In certain embodiments, compositions and methods of the invention can apply to other types of colitis, such as idiopathic colitis (e.g. lymphocytic colitis, collagenous colitis, chemical colitis), ischemic colitis and infectious colitis (e.g. Clostridium difficile, Shigella dysenteriae), and undeterminable type or atypical colitis.

In yet other embodiments, the invention can apply to IBD related disorders. One of common conditions of this group is Irritable Bowel Syndrome (IBS), a spectrum of disorders characterized by the presence of chronic abdominal pain and/or discomfort and alterations in bowel habits, including diarrhea predominant (D-IBS), constipation predominant (C-IBS), and a mixed pattern (M-IBS) types.

In its the broadest sense the invention provides cannabinoid compositions that are applicable to the treatment of IBD using therapeutic methods of the invention. The term "cannabinoids" encompasses herein endocannabinoids, phytocannabinoids or synthetic cannabinoids. Specific cannabinoids include, e.g., THC, CBD and others, as well as encompasses synthetic, semi-synthetic and natural cannabinoid (i.e. purified or extracted from a Cannabis plant).

In its main aspects, the invention pertains to tetrahydrocannabinol-type (THC), cannabidiol-type (CBD) and cannabinol-type (CBN) cannabinoids.

"Tetrahydrocannabinol" (THC) refers herein to a class of psychoactive cannabinoids characterized by high affinity to CBl and CB2 receptors, a molecular formula C2 ₁ H30O2, an average mass of approximately 314.46 Da and a general structure of Formula I.

Formula I

"CannabidioF (CBD) refers herein to a class of non-psychoactive cannabinoids with low affinity to CBl and CB2 receptors, a formula C21H30O2, an average mass of 314.46 Da and a general structure of Formula II.

Formula II

"CannabinoF (CBN) refers to a class of weak psychoactive cannabinoids acting partial agonists of THC at the CBl receptors and CB2 receptors, with a formula C21H26O2, average mass 310.19 Da and a general structure of Formula III.

Formula III

The terms `THC, `CBD`, `CBN` herein encompass isomers, derivatives or precursors, such as (-)-trans-Δ9-tetrahydrocannabinol (Δ9-THC), Δ8-THC, and Δ9-CBD, and also to THC and CBD derived from their respective 2-carboxylic acids (2-COOH), THC-A and CBD-A.

In its numerous compositions, the invention provides compositions derived from or based on the use of a cannabis plant, and thus may be regarded as "phyto-derived compositions" or phyto-derived materials. This term encompasses herbal preparations, concentrated extracts and purified products. Regarding extracts, there are number of methods for producing a concentrated cannabis-derived material, e.g., a filtration, an ice water extraction, butane extraction or CO2 extraction processes, oil extracts made by a solvent evaporation. One of the main sources of cannabinoids is a resin-producing pistillate inflorescences of a female Cannabis plant.

It should be noted in this connection that the presently exemplified preparations of Avidekel in oil were essentially distinct from the original plants by the proportion of active ingredients, e.g., THC and CBD (see Tables 3 and 4).

It should be further noted in this connection that a phyto-derived material and extracts thereof comprise apart from the presently identified active ingredients THC, CBD and CBN, additional cannabinoids and other constituents of plant origin (e.g., terpenes), contributing to distinctive properties thereof in therapeutic impact and applications (see Table 3 and EXAMPLES 2 and 3).

Thus, in its many different aspects the invention provides a phyto-derived composition comprising at least one cannabinoid and at least one terpene for use in a method of treating, alleviating or reducing at least one symptom of IBD, wherein

(a) said composition is derived from at least one of a cannabis plant enriched in THC, a cannabis plant enriched in CBD, a cannabis plant wherein the amounts of THC and CBD are substantially equal,

(b) wherein at least one cannabinoid is selected from THC, CBD, and CBN, and

(c) wherein said at least one terpene is selected from monoterpenes and sesquiterpenes. In some embodiments, compositions of the invention are derived from a female cannabis plant in a dosage form of an oil extract or a dry material, both of which have been presently exemplified.

As has been noted, compositions of the invention can comprise additional cannabinoids of plant origin. The main classes of natural cannabinoids are listed in Table 2 below.

In other words, in numerous embodiments compositions of the invention can comprise a tetrahydrocannabinol-type and cannabinol-type (THC, CBN), a cannabidiol-type (CBD), a cannabigerol-type (CBG), a cannabichromene-type (CBC), a cannabielsoin-type (CBE), an iso- tetrahydrocannabinol-type (iso-THC), a cannabicyclol-type (CBL), a cannabicitran-type (CBT), a derivative, a precursor, or a combination thereof.

Table 2. Main classes of natural cannabinoids

All classes derive from a cannabigerol-type compound and differ mainly how the precursor is cyclized. The classical cannabinoids are derived from their respective 2-carboxylic acids (2-COOH, also denoted with -A) by decarboxylation (catalyzed by heat, light, or alkaline conditions). Tetrahydrocannabinol and cannabidiol acid precursors, THC-A and CBD-A are also relevant to the invention. A number of relevant phytocannabinoids are listed below:

• THC (Tetrahydrocannabinol, including the two isoforms Δ9-THC, A8-THC and the acid form THC-A)

• CBD (Cannabidiol and the acid form CBD-A)

. CBN (Cannabinol)

• CBG (Cannabigerol)

• CBC (Cannabichromene)

• CBL (Cannabicyclol)

• CBV (Cannabivarin)

• THCV (Tetrahydrocannabivarin)

• CBDV (Cannabidivarin)

• CBCV (Cannabichromevarin)

• CBGV (Cannabigerovarin)

• CBGM (Cannabigerol Monomethyl Ether).

Tetrahydrocannabivarin (THCV) is found in certain central Asian and southern African strains of Cannabis.

Cannabidivarin (CBDV) is found in feral Cannabis plants from the northwest Himalayas, and in hashish from Nepal.

Cannabichromene (CBC) is more common in tropical Cannabis varieties.

Thus in numerous embodiments compositions of the invention, apart from THC, CBD and CBN, may also comprise THCA, CBDA, CBG, CBC, CBL, CBV, THCV, CBDV, CBCV, CBGV, CBGM, a derivative, a precursor, or a combination thereof.

Of further relevance to the invention is another group of actives of plant origin, i.e., terpenes (also terpenoids). Terpenes are basic hydrocarbons, whereas terpenoids contain extra functional groups that could be comprised of a range of chemical elements. Terpenoids are flavor and fragrance components Generally Recognized as Safe by the US Food and Drug Administration and other regulatory agencies. Terpenoids are considered potent effectors of animal and human behavior when inhaled from ambient air at serum levels in the single digits ng- mL ^"1 . They are capable of unique therapeutic effects that can contribute to cannabis-based medicinal extracts in increasing their therapeutic index. The nature of phytocannabinoid- terpenoid interaction is still unknown, but it has been acknowledged as synergistic (also referred to an entourage effect) by many examples including treatment of pain, inflammation, depression, anxiety, addiction, epilepsy, cancer, fungal and bacterial infections. In some embodiments, the terpenes and terpenoids are selected from limonene, myrcene, α-pinene, linalool, β-caryophyllene, caryophyllene oxide, nerolidol and phytol.

Terpenoids share a precursor with phytocannabinoids. For the purpose of present disclosure this types of molecules are referred to herein in terms of classes and individually. Classification of terpenes is based on by the number of isoprene units in the molecule. Monoterpenes consist of two isoprene units and have the molecular formula G ₁₀ H ₁₆ . Relevant examples of monoterpenes include limonene, myrcene, linalool or pinene. Sesquiterpenes consist of three isoprene units and have the molecular formula C15H24. Examples of sesquiterpenes include humulene, farnesenes and farnesol.

Various distributions and proportions of terpnoids from these groups in the phyto- derived materials of the invention have been presently exemplified (see Table 3 and Annex A).

Further in this connection, the invention pertains to different types of phyto-derived materials or compositions obtained from distinct types of Cannabis cultivars. The term ^v cultivar ^v generally refers to an assemblage of plants selected for desirable characteristics that are maintained during propagation. The presently exemplified Cannabis cultivars are hybrid varieties of C. Sativa and C. Indica, developed to intensify specific characteristics, such as better survival, boosting of flavor, color and smell, or medicinal properties.

It should be noted that the term `cultivar` usually encompasses a number of strains.

Thus, in some embodiments, the invention pertains to three distinct types of cannabis cultivars presently characterized and distinguished on the basis of cannabinoid and terpene content and distribution, and also specific clinical effect on IBD and IBD sub-types. Specifically, the invention pertains to:

i. Phyto-derived compositions obtained from Cannabis strains enriched in a THC in the range of 16-24% (w/w) and relatively low or almost no CBD, an example of which is Erez.

ii. Phyto-derived compositions obtained from Cannabis strains enriched in CBD in the range of 15-16.5% and particularly low THC as 0.8-3.75% (w/w), exemplified by Avidekel. iii. Phyto-derived material obtained from Cannabis strains having substantially equal ratio of THC:CBD in the range of 6-13% each (w/w), exemplified herein by Midnight.

Further examples of strains of these cultivars (or groups) are shown in Table 3.

Thus, in certain embodiments the invention can be articulated as phyto-derived compositions comprising approximately between 16 and 24% THC and approximately equal or less than 3% CBD (w/w), thus belonging to group (i). More specifically, the THC content of such compositions can be in a range between at least about 10 and 30%, 11 and 29%, 12 and 28%, 13 and 27%, 14 and 26%, 15 and 25%, 16 and 24%, 17 and 23%, 18 and 22% or about 20% (w/w) or lower. It should be noted that such compositions may comprise a low CBD content in the a range between at least about 0.1 and 1%, 1 and 2%, 2 and 3% or 4 and 5% CBD (w/w). In numerous embodiments, the compositions comprise less than 1% CBD (see Table 3).

In some embodiments, the compositions are further characterized by a CBN content of up to 1% (w/w) or optionally in a range between at least about 0.01 and 1%, 0.1 and 0.9%, 0.2 and 0.8%, 0.3 and 0.7%, 0.4 and 0.6% or about 0.5% (w/w) (see EXAMPLE 1 and Table 4).

In some embodiments, the compositions can be further characterized as phy to-derived THC enriched compositions, wherein CBD constitutes up to about 20% relative to THC and CBN - up to about 7% relative to THC (w/w), or CBD in a range between at least about 1 and 5%, 5 and 10%, 10 and 15%, 15 and 20% relative to THC; and CBN in a range between at least about 10 and 8%, 8 and 6%, 6 and 4%, 4 and 2% or 2 and 1% relative to THC (w/w).

In some embodiments, in the phyto-derived THC enriched compositions of the invention, CBD constitutes up to 4 and 6% THC and CBN in an amount less than 5% relative to THC (w/w).

In other embodiments, the invention provides phyto-derived compositions comprising approximately between 14 and 24% CBD and approximately equal or less than 4% relative to THC (w/w), thus belonging to group (ii) above.

The CBD content in the compositions can be in a range between at least about 10 and 30%, 10 and 20%, 11 and 19%, 12 and 18%, 12.5 and 17.5%, 13 and 17%, 13.5 and 16.5%, 14 and 16%, 14.5 and 15.5%, or about 15% or less (w/w). The compositions can further comprise low THC in a range between at least about 0.1 and 1%, 1 and 2%, 2 and 3% or 4 and 5% relative to THC (w/w). In numerous embodiments, such compositions comprise between about 1 and 2% relative to THC (see Table 3).

The composition may be further characterized by a CBN concentration of up to 1% (w/w), or in a range between at least about 0.01 and 1%, 0.1 and 0.9%, 0.2 and 0.8%, 0.3 and 0.7%, 0.4 and 0.6% or about 0.5% (w/w).

These compositions can be further articulated as phyto-derived CBD enriched compositions, wherein CBD constitutes up to about 600% relative to THC and CBN constitutes up to about 25% relative to THC (w/w), or CBD is in a range between at least about 100 and 200%, 200 and 300%, 300 and 400%, 400 and 500%, 500 and 600%, 600 and 700%, 700 and 800%, or up to 1,000% and more relative to THC, and CBN is in a range between at least about 1 and 5%, 5 and 10%, 10 and 15%, 15 and 20%, 20 and 25%, 25 and 30%, and up to 50% or more, relative to THC (w/w).

In some embodiments in a phyto-derived CBD enriched compositions of the invention, CBD may constitute up to 600% relative to THC and up to CBN 50% relative to THC (w/w).

In still other embodiments, the invention provides phyto-derived compositions comprising approximately equal amounts (or concentrations) of THC and CBD, in a range between at least about 6 and 14% and 6 and 16% (w/w), respectively, thus belonging to group (iii) above.

The CBD or THC content in such compositions can be in a range between at least about 1 and 20%, 2.5 and 17.5%, 5 and 15%, 7.5 and 10% or at least about 12 and 13% (w/w). The compositions are further characterized with CBN content of up to 1% (w/w), or in a range between at least about 0.01 and 1%, 0.1 and 0.9%, 0.2 and 0.8%, 0.3 and 0.7%, 0.4 and 0.6% or about 0.5% (w/w).

These compositions can be further articulated as phyto-derived compositions wherein the amounts of THC and CBD are substantially equal, and wherein CBN constitutes up to about 17% relative to THC (w/w), or in a range between at least about 1 and 5%, 5 and 10, 10 and 15%, 15 and 20% relative to THC (w/w).

In some embodiments, in the phyto-derived compositions comprising substantially equal amounts of THC and CBD, CBN constitutes up to about 7 and 10% relative to THC (w/w).

The role of THC and CBD in the above groups of compositions, in terms of differential therapeutic effects, has been previously discussed. The role of CBN should be perceived in light of the fact that CBN acts as a partial agonists of THC at the CB 1 receptors and CB2 receptors. Therefore, various proportions of THC, CBD and CBN in these groups should have direct bearing on their therapeutic properties as reflected in EXAMPLES 2-7.

Still from another point of view, the compositions of group (iii) can be described as compositions wherein the THC:CBD ratio is about 1 : 1, or substantially 1: 1 (w/w), or specifically a ratio in a range between at least about 1.5: 1 and 1 :1.5 (w/w), and the compositions of groups (i) and (ii) are those wherein said ratio is other than above.

In further embodiments, compositions administered in step (i) are administered by smoking, inhalation, vaporization or a combination thereof, and compositions administrated in step (ii) are orally administered.

Combination therapies have been investigated in detail in EXAMPLE 7. Surprising benefits of a combination therapy using THC enriched and CBD enriched compositions in succession have been demonstrated by significant improvement of disease indices, significantly lower number and severity of adverse events, and improvement in general quality of life compared to monotherapies using THC enriched or CBD enriched compositions.

Most surprisingly, such combination therapies proved to be more beneficial than monotherapies using THC and CBD in combination, when administered in the same composition (i.e., Midnight).

Moreover, combination therapies proved to be more efficient in the management of pain for which THC enriched compositions have been considered, so far, more effective.

With respect to the presently exemplified dosage forms, THC enriched compositions of the invention in the form of cigarettes or those comprising equal THC and CBD are intended for immediate relief of IBD symptoms and/or also colitis. The absolute amount of THC delivered in the smoke varies widely and has been estimated at between 20 and 70%, the remainder being lost through combustion or side-stream smoke. Tolerable doses of the THC in the form of cigarettes can reach up to between 60 and 70 mg per day.

In terms of daily doses, in certain embodiments such cigarettes are consumed daily, preferably before sleep, or with the onset of symptom(s), as one or two cigarettes per day, or more, as an occasional, a periodic or a continuous treatment. In terms of oral dosage forms, specifically oil extracts enriched in CBD, these are intended for prolonged alleviation of symptom(s) of IBD and/or Crohn's disease. This type of compositions is consumed in the form of drops. A drop of Avidekel oil, for example, 0.04 ml in volume has been estimated as having about 6 mg CBD and 1.5 mg THC.

In some embodiments, a single oral dosage form comprises about up to 14-15 drops, or in the range of 1-2, 2-4, 4-6, 6-8, 8-10, 10-12, 12-14 drops or more, with average CBD/THC content per administration in a range between at least about 10-100 mg, 10-80 mg, 10-70 mg, 10-60 mg, or 10-50 mg CBD, or 15-45 mg, 20-40 mg, 25-35 mg, or about 30 mg CBD, and 5- 8 mg, 5.5-7.5 mg, 6-7 mg, or about 6.5 mg THC.

It should be appreciated that in certain embodiments a single oral dosage form comprises an average THC content of less than 5 mg per administration.

In terms of daily doses, to obtain prolonged effects said oral dosage forms are administered at least once a day, two times a day or three times a day or more, with average daily doses in a range between at least about 50-100 mg, 100-150 mg, 150-200 mg, 200-250 mg CBD, or more, with maximal daily doses up to at least about 300-500 mg CBD per day, and 15-25, 16-24, 17-23, 18-22, 19-20 mg THC, or less.

Further, in certain embodiments to obtain prolonged and sustainable effects said CBD enriched oral dosage forms are administered continuously for a period of at least about up to 4, 5, 6, 7, 8, 9, 10, 11, 12 weeks, months and years, or the entire period of persistence of symptom(s).

In terms of daily regimen, such oral dosage forms are taken during the day as periodic or continuous treatment.

In one of its further aspects, the invention provides use of phyto-derived compositions of the invention for the manufacture of a medicament for the treatment or alleviation or a reduction of at least one symptom of IBD.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present disclosure, the preferred methods and materials are now described.

EXAMPLES

Materials and Methods

1. Biochemical analyses of phvto-derived compositions of the invention

Cannabinoid and terpene contend was determined using standard procedures for gas chromatography-mass spectrometry (GC-MS) analysis. In brief, dry plant-derived material were powdered, extracted with an organic solvent ( n-hexane), filtered, and samples (1 were loaded on GC-MS (Hewlett Packard G 1800B GCD system with a HP-5971 gas chromatograph with electron ionization detector). Compounds of interest were identified by comparison with standards, retention times, Kovats indices, and available libraries (software GCD Plus Chemstation). Ratios of specific cannabinoids (THC, CBD) were determined relative to total cannabinoid content, and ratios of specific terpenes ratios - to main terpene (100%).

2. Preparation of oil extracts from flower-derived material

Oil extracts were prepared from Avidekel strain in the presence of olive oil using previously described procedures, i.e., C02 extraction processes or solvent evaporation using ethanol. Cannabinoid content of oil preparations was determined using LC-MS or HPLC by means of standard procedures. Batches of oil extracts were monitored according to ISO9001 and HACCP standards of quality management.

3. Dose titration in clinical trials

Each patient participating in the clinical studies was subjected to titration of individual dose. The duration of titration period was approximately 3 weeks, wherein the initial dose and/or dose regimen (number of administrations per day) were gradually incremented to achieve maximal clinical effect with minimal adverse reactions (evaluated according to mental status, behavioral and psychological symptoms of dementia (BPSD), decline in motor function and stability, significant changes in blood pressure, sugar levels, respiration rates, pulse). Daily doses did not exceeded 400 mg active cannabinoids, CBD and THC. 4. Prospective clinical study in patients with Crohn's disease

Patients were randomly assigned to receive either Avidekel oil extract comprising THC 4% and CBD 16% (THC:CBD ratio 1 :4), or placebo comprising olive oil with chlorophyll. Both patients and investigators were blinded to the assignment procedure. Patients were subjected to follow up period of 8 weeks of treatment and wash out period of additional 2 weeks. The follow up data at baseline and weeks 2, 8, and 10 included: clinical interview, physical examination, assessment of disease activity (CDAI), and blood tests (complete blood count, liver and kidney function, C-reactive protein (CRP) marker for inflammation), SES colonoscopy, calprotectin test for direct intestinal inflammation, and measurement of physical and mental health status using and reporting on side effects using a standardized Quality of Life (SF-36) questionnaire.

5. Pharmacokinetic studies in patients with Crohn's disease

Patients with Crohn's disease (N=7) participating in the prospective clinical trial. Blood samples were withdrawn at time 0 and after administration of Avidekel oil extract, a sublingual dose 4 drops. Blood samples were withdrawn in intervals of 15, 30, 45, 60 and 90 min., and 2, 3, 4, 5, and 6 h., and stored at -70 ^° C until analysis at NMS Labs using LC-MS/MS. The analysis related to two main cannabinoids and two metabolites, including THC (A ⁹ -THC), CBD, 11- Hydroxy A ⁹ -THC (active metabolite) and Δ ⁹ Carboxy THC (inactive metabolite).

6. Clinical study in patients with ulcerative colitis

Patients were randomly assigned to receive either Erez in the form of cigarettes containing 1 gr flower-derived material comprising THC 23% or placebo cigarettes. Patients were subjected to follow up period of 8 weeks of treatment and wash out period of additional 2 weeks. The follow up data at baseline and weeks 2, 8, and 10 included: clinical interview, physical examination, assessment of disease activity (DAI), and blood tests (complete blood count, liver and kidney function, C-reactive protein (CRP) marker for inflammation), SES colonoscopy, calprotectin test for direct intestinal inflammation, and measurement of physical and mental health status using and reporting on side effects using a standardized Quality of Life (SF-36) questionnaire.

7. Retrospective study of patients receiving mono- or combination therapies

Patients' data was retrieved from the company database including demographic and clinical data and clinical follow up on more than 1800 patients with various clinical conditions who received phyto-derived cannabinoid compositions of the invention under specified regimens. Data on patients with clinical diagnosis of IBD, Crohn's disease and colitis, was selected for this study (N=291). Data included clinical anamnesis, physical examination and clinical evaluation of IBD in relating to DAI clinical severity score, biochemical tests for indices of blood inflammation, faecal calprotectin, and colonoscopy using MAYO and CD-SES scores. A further evaluation relating indices of patient's life-style, quality of life, personal preferences, etc, was retrieved from QOL (SF-36) questionnaires. Additional data related to reports on the presence of adverse events by study physicians, during at least three following visits, during the first month and the first year. A group of patients had more than 6 months experience with phyto-derived compositions of the invention (N=142). Data was subjected to relevant variance analyses (e.g., T-test ANOVA, Mann-Whitney) to reveal associations with beneficial treatment outcomes (p<0.05 was considered statistically significant).

EXAMPLE 1

la. Cannabinoid and terpene profiles in the compositions of the invention

Table 3 shows relative content of cannabinoids and terpenes in phyto-derived compostions of the invention, including the two main cannabinoids (THC and CBD ratios) and a number of terpenes of monoterpenes (myrcene, limonene, β-pinene) and sesquiterpenes (β- caryophyllene, guaiol, β-farnesene) classes. The complete terpene data is provided in Annex A.

Table 3. Profiles of representative cannabinoids and terpenes in phyto-derived material Additional data on relative content cannabinoids in phyto-derived material is presented below:

• Avidekel was identified with a CBD-enriched content, i.e., 14-22% CBD, 0-2% THC and 0-1% CBN (w/w) in a flower-derived material (w/w);

• Rafael, similar to Avidekel, was identified with 16-24% CBD, 0-2% THC 0-1% CBN (w/w) regarding the same;

• Erez was identified with a THC-enriched content, i.e., 16-24% THC, 0-2.5% CBD and 0-1% CBN (w/w);

• Alaska, Eran-Almog, Dorit, Omer, Shira, Or (and a more recent strain Zohar) showed similar profiles;

• Midnight, in contrast, were identified with equal or almost equal THC and CBD, i.e., 8-16% CBD, 6-14% THC, 0-1% CBN (w/w).

• Mango was also identified with equal THC and CBD in the range of 6-9% (w/w).

This data showed that phyto-derived materials from specific strains were identified with particular relative content (ratio) of cannabinoids and terpenes. Specifically, with regard to the relative content of THC and CBD, the phyto-derived material of the invention were grouped into three main categories:

i - THC enriched material, e.g., derived from Erez, Alaska, Eran -Almog;

ii - CBD enriched material, e.g., derived from Avidekel, Refael; and

iii - material derived from strains wherein THC and CBD content is approximately equal, e.g., Midnight.

With regard to terpenes, phyto-derived materials from specific strains were identified with specific relative content of monoterpenes and sesquiterpenes, and specific terpenes of these classes. Significant differences were observed in relative content of myrcene, limonene (monoterpenes), e.g., Dorit and Avidekel, and of β-caryophyllene, guaiol, e.g., Midnight and Jasmin.

These biochemical properties of phyto-derived composition of the invention were further related to differential effects on partial symptoms of IBD and general alleviation of IBD condition. lb. Relative content of main cannabinoids in oil extract of Avidekel

Table 4 shows main cannabinoid profiles in oil extracts of Avidekel, CBD enriched, material, as determined in two independent experiments using HPLC.

In terms of relative cannabinoid content, the investigational product contained THC:CBD ratio of 1:4.

In terms of total cannabinoid content, a drop of Avidekel oil estimated at approximately 0.04 ml contained approximately 1.6 mg THC and 6.54 mg CBD.

In terms of cannabinoid therapeutic dose, dosage, patients received 4-5 drops per administration, sublingual, 3-times per day. The control group received placebo containing olive oil and chlorophyll.

In the subsequently described retrospective study IBD patients were using Avidekel products with dose regimens as described above, alone or in combination with other THC enriched products administered by smoking or inhalation. A number of patients were using Avidekel products with products wherein THC:CBD are in equal proportions. Certain patients substituted Avidekel products with analogous CBD enriched products such as Refael administered by smoking or inhalation, according to personal preferences.

EXAMPLE 2

High CBD compositions (Avidekel) are effective for the treatment of Crohn's disease

Patients with differential diagnosis of Crohn's disease received Avidekel oil (N=18) or a placebo (N=21) administered sublingually as 4-5 drops, 3-times a day for a period of 8 weeks. All patients additionally received a classical anti-inflammatory therapy with at least one drug from group of immunosuppressants, e.g., azathioprine (Imuran), mercaptopurine (Purinethol), methotrexate (Rheumatrex), cyclosporine (Neoral); biological drugs, e.g. TNF inhibiting antibodies Adalimumab (Humira), Infliximab (Remicade); corticosteroids, e.g., prednisone (generic); anti-inflammatory 5-aminosalicylic acid (5-ASA), compounds (Delzicol, Asacol, Pentasa), or a combination thereof. Table 5 shows clinical characteristics of patients in the treatment and control groups.

Table 5. Clinical characteristics of patients at baseline. CD-SES: Simple Endoscopic Score for Crohn ^' s Disease; DAI: Crohn's Disease Activity Index; QOL: Quality Of Life (SF-36); WBS: White Blood cells count; HB: Hemoglobin count; HCT: Hematocrit count; CRP: C-reactive protein in blood; Calprotectin: feca!; NS:Non- Significant.

Avidekel oil used in the study comprised THC:CBD ratio of approximately 1 :4 (w/w). In terms of dosage, Avidekel oil drop (0.04 ml volume) comprised approximately 3.7% THC and 15% CBD (w/w), and in terms of content - approximately 1.5 mg THC and 6 mg CBD.

In terms of an active drug dose per administration, an average drug dose was in the range of approximately 6-7.5 mg THC and 24-30 mg CBD. Doses did not exceed a maximum of 15 drops per administration (24 mg of THC and 98.1 mg of CBD). In order to achieve an optimal therapeutic dose, each patient was subjected 3 weeks titration period, wherein the number of drops per administration and/or the number of administrations per day (morning, day, night) were gradually incremented. Optimal therapeutic dose was evaluated as a daily dose with a maximal impact on clinical indices of the disease with no significant adverse reactions.

In terms of daily doses, an average administration dose was in the range of approximately 18-23 mg THC and 72-90 mg CBD. Daily doses did not exceeded 400 mg actives, CBD and THC.

The result of this study, as reported by patients and physicians, showed significant improvements of clinical indices of Crohn's disease, general quality of life and treatment compliance in the group of patients treated with Avidekel oil compared to those in the placebo group. Figs. 1A-1I show general trends observed in this study, in the Avidekel treated group (solid black lines) and placebo (dotted lines).

Specifically, the most significant beneficial effect were observed in CDAI and QOL (SF-36) scores. At 2- and 8-weeks' time points, CDAI score decreased from from 284.6+74.6 to 118.6+71.5 and QOL score increased from 74.0+19.8 to 96.3+17.6 in the Avidekel treated group compared to placebo wherein these scores remained relatively unchanged, i.e., CDAI of 286.7+112.0 to 212.6+102.4 and QOL of 72.6+13.8 to 79.9+16.2, respectively).

On the basis of this findings it is suggested that significant improvement in all study parameters could be observed in a study of a larger group of patients. Such study is currently ongoing. Comparative studies are currently carried out in patients with Crohn's disease, including oil extracts with THC:CBD ratio 1:6 and Sativex (ratio 1 : 1). A preliminary study including Avidekel oil (THC:CBD ratio 1 :4) and a commercial preparation of dronabinol (Marinol, a synthetic THC in sesame oil) showed no significant effects of Marinol on clinical indices of the disease and general quality of life., and was therefore terminated due to relative side effects and poor patients' compliance.

Pharmacokinetic studies were performed in a group of patients from the above trial (N=7), while relating to two main cannabinoids, THC (A ⁹ -THC) and CBD, and two metabolites, 11 -Hydroxy A ⁹ -THC (active metabolite) and Δ ⁹ Carboxy THC (inactive metabolite). Fig. 2A-2D show mean cannabinoid blood levels after administration of a single dose of Avidekel oil (6.4 mg A ⁹ -THC and 26 mg CBD).

Specifically, maximal mean A ⁹ -THC values of 2.3+2.2 ng/mL were observed at 90 min. until 120 min., with a continuous drop until 6 h. after administration wherein A ⁹ -THC levels were typical to those after 24 hours of Cannabis washout. A similar profile was observed for CBD pharmacokinetics with maximal mean CBD values of 6.2+5.9 ng/mL at 90 min. until 120 min. with a continuous drop until 6 h. after administration. Regarding the two metabolites, 11- Hydroxy A ⁹ -THC maximal mean levels reached 4.5+4.2 ng/mL at 90 min. until 120 min. and dropped to 1.9+1.1 ng/mL. For Δ ⁹ Carboxy THC in contrast, mean levels at after 90 min. reached 34.5+47.7 ng/mL but continued to rise during the 6 h. period up to 75.5+77.0 ng/mL. These data need to be verified in further studies. Comparative pharmacokinetic studies are currently carried out in Crohn's patients, including oil extracts comprising THC:CBD ratio 1 :6 and Sativex (ratio 1: 1).

EXAMPLE 3

High THC compositions (Erez) are effective for the treatment of colitis

Patients with differential diagnosis of ulcerative colitis received Erez cigarettes (N=14) or placebo cigarettes (N=13), wherein Erez cigarettes (1 g. dry weight per cigarette, THC content of approximately 23% w/w and almost no CBD), or placebo cigarettes were administered at a daily dose of two cigarettes per day for a period of at least 8 weeks. All patients additionally received a classical anti-inflammatory therapy with at least one drug from group of immunosuppressants, biological drugs, corticosteroids, anti-inflammatory 5-ASA compounds or a combination thereof. Table 6 shows clinical characteristics of patients in the treatment and control groups.

Table 6. Clinical characteristics of patients at baseline. MAYO score: Mayo Scoring System for Assessment of Ulcerative Colitis Activity; IQR: Interquartile Range; DAI: Disease Activity Index; QOL: Quality Of Life (SF-36); WBS: White Blood cells count; HB: Hemoglobin count; HCT: Hematocrit count; CRP: C- reaciive protein in blood; Calprotectin: fecal; NS:Non-Significant.

Erez cigarettes used in the study comprised 23 % THC (w/w) with almost no traceable CBD, and in terms of content - approximately 0.23 gr. THC.

In terms of an active drug dose per administration, since Erez was consumed by smoking or inhalation, this makes estimation of the administered drug dose or a daily dose highly inaccurate and highly dependent on personal use. Daily doses did not exceed a maximum of 2 cigarettes per day.

The result of this study, as reported by patients and physicians, showed significant improvements of clinical indices of colitis, general quality of life and treatment compliance in the group of patients treated with Erez compared to placebo. Figures 3A-3I show general trends observed in this study, the Avidekel treated group (solid black lines) and placebo (dotted lines).

Specifically , the most significant beneficial effect were observed in DAI and QOL (SF-36). scores. In the Erez group DAI score decreased from 10.2 ±3.3 at the baseline to 3.9 ±3.3 after 8 weeks treatment compared to 10.6 ±2.8 to 8.2 ±2.1 in the placebo (p<0.01). Analogously, QOL score in the Erez group increased from 76.0 ±21.0 to 99.6 ±19.2 comparrent to 71.6 ±13.7 to 80.8 ±14.0 in placebo (p<0.01).

On the basis of this findings it is suggested that significant improvement in all study parameters could be observed in a study of a larger group of patients. Such study is currently ongoing.

Further comparative studies are currently conducted in patients with various types of IBD treated with compositions of the invention with various THC:CBD:terpene content (ratio) as opposed to other commercially available cannabinoid compositions.

EXAMPLE 4

Avidekel oil- extract of is effective for prolonged management and treatment of IBD

Patients diagnosed with IBD (N=50) received an oil-based extract of Avidekel or a placebo oil, the preparations were orally administered as 4-5 drops, three times a day, for a period of 8 weeks. Drug regiments were similar to EXAMPLE 2 as well monitoring of the disease condition. After monitoring for at least 8 weeks, patients and physicians reported significant improvements relating to all clinical indices of IBD and also to indices of general quality of life and treatment compliance. Patients were compliant with Avidekel oil being administered during waking hours.

EXAMPLE 5

Erez cigarettes are effective for an immediate alleviation of IBD symptoms

Patients diagnosed with IBD (N=30) received Erez cigarettes (0.5-1 g. dry weight per cigarette) consumed as two cigarettes per day for a period of at least 8 weeks, or placebo cigarettes. Drug regiments were similar to EXAMPLE 3 as well monitoring of the disease condition.

During the monitoring period and two weeks after, patients and physicians reported significant improvements relating to immediate relief of symptoms of IBD, including pain. Patients were more compliant with administration of Erez cigarettes before sleep.

EXAMPLE 6

Midnight is an effective substitute for Erez in non-compliant patients

IBD patients non-compliant with Erez due to psychotropic effects (about 20%). received Midnight in the form of cigarettes wherein THC:CBD content is approximately equal, administered as two cigarettes per day for a period of at least 8 weeks, during the day and/or before sleep. Midnight proved to be an effective substitute for Erez, particularly considering patients and physicians reporting on immediate relief of IBD symptoms, including pain, gain of appetite, and improvement in general quality of life, in absence of or with a significant reduction of adverse events compared to a previous experience with Erez.

EXAMPLE 7

Surprising beneficial effects of combination therapies for a long term treatment and management of IBD

Data on patients with clinical diagnosis of IBD, Crohn's disease and colitis, was selected for this study. Data included clinical anamnesis, physical examination and clinical evaluation of IBD in relating to DAI clinical severity score, biochemical and blood tests for indices of inflammation, calprotectin, and colonoscopy using standard scores, and also evaluation of patient's life-style, quality of life, personal preferences retrieved from QOL (SF-36) questionnaires. Additional data included reporting of adverse events during the first month and the first year.

The IBD group (N=291) included 169 males (58%), mean age 39.8 years (SD=16.9) with 142 patients having more than 6 months experience with phyto-derived compositions of the invention (49%). The majority of patients reported on pain (94%) of various degrees on a subjective severity scale (0-10). Within the group of 142 patients completing the follow-up questionnaire, 65 patients (46%) reported on preference to a combination therapy including CBD enriched and THC enriched compositions administered in succession, CBD enriched composition - preferably during the day, and THC enriched compositions - preferably before sleep; 77 patients (54%) reported preference of a monotherapy - preferably THC enriched compositions; 8 patients (6%) reported on preference to Midnight including approximately equal THC: CBD content.

Data analysis of patients receiving a combination therapy versus those receiving a monotherapy showed significant improvement of disease indices in the combination therapy group compared to monotherapy group (p<0.001). Most notably, patients receiving combination therapy with CBD-enriched and THC enriched compositions (in succession) performed better than patients treated with compositions comprising THC and CBD in equal amounts (Midnight).

Further patients receiving combination therapy reported on significantly lower number and severity of adverse events (nausea, dizziness, dry eyes syndrome, psychoactive symptoms, sleepiness, general weakness) compared to the monotherapy group (p<0.001). Also in this analysis, patients treated with CBD-enriched and THC enriched combination therapy in succession performed better than patients treated with Midnight (THC:CBD equal).

Further, in the analysis of a reduction of pain, patients on CBD-enriched and THC enriched combination therapy reported on a more significant alleviation of pain, in terms of number of incident, severity score and longitudinal management of pain, than patients on monotherapy (p<0.001), including Midnight. This finding is moreover surprising since THC- enriched strains and cannabinoid compositions have been considered, so far, more effective for the treatment of pain.

These finding suggest that combination therapies including CBD-enriched and THC enriched compositions of the invention are more efficacious for long term treatment and management of IBD than monotherapies, even those including THC and CBD. These effects can be further enhanced by specific dose regiments and personalized approached. Studies of advantageous effects of combination therapies using various phyto-derived material, methods of extraction and dose regimens are currently ongoing.
