FIELD OF THE INVENTIO

The present invention is in the field of pharmaceutical compositions ^' and discloses novel compositions for the oral administration of Caiwiabinoid Receptor Type 2 (CB2) modulators and optionally of an antipsychotic agent for the treatment of mental disorders,

BACKGROUND

Mental disorders can arise from multiple sources and affect a large percentage of the population. There are a range of different types of treatment of mental disorders and what is most suitable depends on the disorder and oft the individual.

Schizophrenia is mental disorder which affects about 1% of the population (Lewis <¾ L ieberman, 2000), and genetic and environmental factors underlie the eventual eruptio of the disease (Ross, 2006 ^' }. Schizophrenia is often chronic, characterized by deterioration of social contact cognitive deficits, anxiety and depression, resulting in suicide in about 10% of the schizophrenic population (Lewis <¾ Liebemian, 2000).

Another important mental disorder is tic disorders, specifically, Tourette syndrome (TS), which is characterized, by multi le motor tics and at least one vocal tic. Starting at childhood, TS includes ties like blinking, coughing,, throat clearing, sniffing and facial, movements. About 1 % of the school-age children and adolescents have Toilette's,

In the B LB system the i.O surfactant s assigned a number between I and 20, Surfactants with BLB values -of .between 3 and 6 are lipophilic and form water- in-oil emulsions, while values, of 8 to 18 indicate predominantly hydrophilic charactensii.es and the formation of o.il a-water emulsions.

Pharmaceutical compositions suitable for implementing; the teachings herein include compositions comprising: active ingredients in an amount effective to achieve the intended purpose (a therapeutically effective amount).. Determination of a therapeutically effective amount is well within the capability of those skilled in the art, for example, is initially estimated from animal models such as rats, mice, monkey or pigs.

The terms -self-emulsifying and self-emulsiftahSe, as used herein, can be used rnterdtangeably,

SEDDS is a broad term associated with the production of emulsions with droplet, size rangin from a few nanometers to several microns, which can. be classified as self- licro- emulsifying drag deli .very systems (SMEDDS) and self-nanoentulsifying drug deliver system (SNEDDS) (Zanchetta B. et a!. Adv. Chem. Eng. 2015, 5:3).

SEDDS formulatio is a liquid composition. SEDDS are waterless: compositions which upon, dilution with water containing media r body fluid self-emulsify forming an oil-in- water emulsion. According to the specific composition and mode of preparation, SEDDS may form, ^• upon, dilution with aqueous media, emulsions with different droplet sizes.

The present invention provides a highly effective stable oral composition comprising a therapeutically effective amount of at least one CB2 receptor seieciive or highly selective agonist in substantially pure form in a self-emtdsifying vehicle and optionally a therapeutically effeciiv amount of at least one antipsychotic agent in a sei.f-em.dsityi.ng vehicle, for use i treating: a mental disorder in a patient in need thereof. In the context of this disclosure, the term "seieciive" when used alone is meant genetically, meaning that it includes als highl selective CB2 receptor ^■ modulator, in some embodiments, the CB2:CB1 Ki ratio for high affinity li gauds with Ki 1-50 nM ratio is about 1 .500 while the CB2;CBI Ki for low affinity !igands wit Ki 50-200 nM ratio is about 1 :50.

In some aspects of the iirvention, some of the CB2 receptor selective or highl selective agonists can be synthetic cannabinoids or cannabinoids of plant origin (phytocannabinoids) such as cannabis, hemp, cloves, malabathrum, West African pepper, hops, or gano, etc

The cannabi noids are a group of chemical compounds of v ery diverse structures. The most important types of phytocaimabinoids are: cannabigerol-type (CBG), cannabi chrornene-type (CBC), cannab idiol-t pe (CBD), tetrahydrocannabinol- and cannabin l- type -(TH€ _S CBN), cannabielsoin-type (CBB),. iso-t6trahy<frocannabittol-iype (iso-THC), cannahicycloi-iype (CBL} _? and ca na icitran-type (CBT)÷ The most studied cannabinoids are

5 TH€ ₅ CBD, CBG and ^' CBN. At least 85 different eannahinoids have been isolated from the cannabis plant. These compounds have very different affinities for the cannahinoi or non~ eannahinoid receptors. Som are neutral Uganda (no or very little affinity- to the eannabinoid receptors), some are CB l and€82 receptor agonists, some are- CB 1 arid€B2 -receptor partial agonists, some are CBl arid CB2 receptor antagonists, some a e CBl and CB2 receptor inverse-

10 agonists, some are combination thereof and only a few are specific and selective agonist or antagonists. Some caiiftabitioids (like CBD, CBDA, C-BDV, CBG, CBGA, CBGV, TH and ^' THCV) are inhibitors of the GPiRSS Hgand .(Anav -Goffer et al. 2012).

THC. THCV and CBN are non-selective CB ! and CB2 receptor ligands. tact delta-9- THC is -a weak CBl and CB2 receptor partial agonis (Childers, 2006}., thus that in the presence

I S of a more potent selective agonist de!ta-9-THC will antagonize its effects. CBC, CBD, ^: C-BDV, CBD.A, CBG, CBGV, CBGA, THCA and TI ICV have not been reported to activate the CBl or CB2 receptors with significant potency (Handbook of Cannabis, Oxford University Press, R.G. Pert wee Editor, p. 137, 2014). Summing up, unlike the CB2 receptor selective agonists of this, invention, none of the above ca-nnabmoids. are selective or highly selective -CB2 recepto

10 agonists _*

Most of the commercially available cannabinoids are i fact loosely defined mixtures of a cannabiiioid with, other cannabinoids, impurities, geometrical isomers and enantiomers. The cannabinoid's proneness to spontaneous ^' oxidation complicates even more the purity issue- -of these -substances.

IS The affinities for two different cannabirsoid receptors (CBl- and CB2 receptors) complicate the issue of pharmacological activity. Therefore, the present disclosure uses as active agents well-defined stable highly pine CB2 receptor selective agonists, ost of the CB2 receptor agonists of this invention are potent selective CB2 receptor agonists.

The mental disorder to be treated by the compositions and methods described herein can iO be selected from the group consisting of schizophrenia, schizoaffective disorder, bipolar disorder 1 and 11, unipolar disorder, multiple personality disorder, psychotic disorders, depression, psychotic depression, depressive disorders, major depressiv disorder, depression associated with tic disorders, epilepsy, anxiety disorders, autistic spectrum disorder, enuresis and addiction, Asperger syndrome, op ositional defiant disorder, behavioral disturbance, agitation, psychosis/agitation associated wit Alzheimer's disease, psychosis associated- with Parkinson's disease, personality disorders, borderline personality disorder, avoidant personality disorder, aittn tion-deficit ^' hyperactive disorder (ADHD, ADD, HD), mania, dementia, anorexia, anorexi nervosa, anxiety, generalized anxiety disorder, social anxiety disorder, body dtsmographie disorder, obsessive compulsive disorder, paranoid disorder, nightmares, agitation, posi-traumatic stress disorder (PTSD), severe mood dysregiilatio.ti and Toureite's syndrome.

Some embodiments of the invention relate to compositions comprising -at least one

Cannabinoid Receptor Type 2 (CB2) receptor selecti ve agonist as sole active, methods of making the compositions and methods using CB2 receptor selecti ve agonists fo the treatment of menial disorders. Some other embodiments relate to compositions comprising CB2 receptor selective agonists in combination with at least: one antipsychotic agent in a self enmisifying vehicle,

Othe embodiments of the invention relate to compositions comprising beta- earyophyilene (BCP) as sole CB2 receptor selective agonist, methods of making th compositions and methods usin BCP for the treatment of schizophrenia. The use of BCP in schizophrenia disclosed in this invention is unexpected and .surprising, as cannabi.iioi.ds are know to cause aggravation of psychosis i patients with schizophrenia. Thus, for example, TBC is known to induce a range of positive symptoms of schizophrenia (according io The Diagnostic and Statistical Manna! of Menial Disorders (DS )), and THC treated schisophrenic patients experienced a exacerbation of symptom (Deepak Cyril D'Soum et ah Eur Arch Psychiatry Clin. Neurosci. 2009 Oct; 259(7): 413-43 1). In addition, while TH can induce anxiety in. some patients, BCP reduces anxiety.

When f u d i . nature, BCP typically appears as a mixture of two isomers E-BCP and Z~

BCP, together with substantially inactiv sesquiterpenes such as atpha-hurnulene and derivatives such as BCP oxide, Typically, natural, sour es include a greate proportion of E-BCP th n Z- BCP.

For- implementing the teachings herein, the BCP includes both E-BCP and Z-BCP, alone or in combination.

The Cannabinoid Receptor Type 2 (CB2) is a guanine nucleotide-b.irid.ing protei (G protein }~conpled receptor that In humans is encoded by die CNR2 gene.

Recent studies have identified the eannabinoid CB2 receptor in the brain. Dp-regulation of CB2 receptor expression in he. brain dining central nervous system pathologies has been demonstrated for certain neurological, diseases.

In some emb diment _: , the CB2 receptor selective agonist in the compositions of this invention .is selected from the group comprising BCP, [( l R.,2R. _> 5R)-2-[2 _J 6-d :methoxy-4-(2- m.ethy1oetan-2-y!)phenyl] -7,7-dimethy I -4-bicyclo [3, 1 , 1 Jhept-3-enyl] methanol (Ht -308), filJ- 433, eU-910, HU- 1.4.

BCP exhibits chirahty at positions 1 and 9 and is the 1R,9S enaniiomer, the (-) f rm,

RU-308 (f( Ill _J 2]l,5R)-2-[2 _s 6-dimfithoxy-4-(2-nie yioctan-2 }-7,7- d ^' imethyi- - bicycio[3,l . l]hept-3-enyl] methanol) is a synthetic cannabinoid, . which is highly selective for die CB2 receptor.

The fact that prally-adnsinistered BC is absorbed by the digestive tract and becomes systemically available and its apparent substantia! notMoxicity makes BCP attractive as a potential active pharmaceutical ingredient.

However, BCP whose main commercial vise is as food additive, is not commercially available in pharmaceutical grade. The food additive grade contains a relatively low percentage of BCP, contains impurities like BCP oxide, alpha-humulene and BCP (+) enaniiooier and i not well defined analytically.

According: to Chicca A, et al (Chem. Biol. 201,4, 9, 1499-1507), BCP-oxide and alpha- tnumdene's inactivity suggest the existence of a specific ses iiiterpei e pharmacophore for CB2 receptor binding in BCP only but not in BCP-oxide and alpha iumulene.

The BCP impurities can have potential negative skie-elTects on the therapeinie effect of the compositions of this invention.

For example, alpha- homulene is a skin, eyes and respiratory irritant, according to its

MSDS. Also, BCP oxide was found to be an. allergen (Skbld M, arlberg AT. Marina M, Borje A, Food Chem, Toxicol 2006 Apr;44(4):53S-4S).

in an. embodiment, th compositions of this invention use BCP (and/or other CB2 modulators) i substantially pure form, being substantially free of BCP oxid and alphatiuniylene,

Chaves (Chaves JS, Plant Med. 2008 Nov; 74( 14): 1678-83) reporte thai aipha- humulene exhibited a rapid onset arid relatively good absorptio following oral and topical administration. These findings further contribute to an explanation of the topical and systemie anti-inflammatory and antinociceptive properties previously reported for the essential oil and fo alpha-humulene obtained from Cordia verbenacea. Humulen is irritant, but only in high doses. It is documented that BCP lias a potentiating effect on homuiene. T us, Legault p. Pliarm, Pharmacol, 2007 Dec; 59(12): 1643-7) reports a enharK-eineni of the anticancer effect of huHittlene by BCP.

It is therefore interesting to determine th activity of BCP/alpba~liumii!ene combinations, The experimental data (see examples) suggests that BCP/a!pha-hun dene combinations are therapeutically active.

Aspects of the invention relate to compositions -comprising a combination of BC P and alpha-humulene. optionally with traces of other ingredients like BCP-oxide. in -some embodifnents, there are provided co positions comprising .from about 85%w w t about 99%w/w BCP and from about l %w/w to about 15%w/w humuieiie, with traces of other ingredients- like BCP-oxide. In some embodiments, there at e provided compositions ^■ .comprising, from about 85%w w to about 99%w/w BCP and from about I%w/w to about bnmi ene.

In some embodiments, there is provided a method of treatment of a mental disorder in a patient in need thereof by administration of a composition comprising from aboot ¾5 w ^' w to about 99%w/\v BCP and from .l% v/w to 15¾w/w humuiene... a self-eraulsifyiii . vehicle, i some embodiments, there is provided a method, of treatment of a mental disorder in a patient in need thereof, by administration of a composition comprising from about 83%w to about 99%w/w BCP and from l%w/w to 15%w/w huniulene, a self-emulsifying vehicle and optionally one or more of the following: a therapeutically effective amours* of either at leas one antipsychotic agent, at least one GPR55 modulator, at least one ani nflannuaiory agent, at least one enzyme enhancer, at least on enzyme inhibitor, at least one antidepressant, at least one anxiolytic, at least one terpene o terpenoid, at least one anti -diabetic agent, at least cognitive ^• enhancer- agent or any combinations of the foregoing, in some embodiments, the composition. can comprise from about 85%w/w to about 99% /w BCP and from about !%w;/w to about 13%w/w humulene, with traces of other ingredients like BCP-oxide.

One of the drawbacks of BCP is its pmneness to autoxkiatkm, Beia- aiyophy IS ene starts to oxidize immediately when air exposed, and after 5 weeks almost 50% of the original compound is consumed. ^■ Car ophyllene oxide was found to be the major oxidation product ((Skold M. Karlfoerg AT, Matuta M, Borje A, Food Chem. Toxicol. 2006 Apr;44(4);538-43)). The practical effect of this instability is that conventional compositions- containing the compounds have relatively short shelf liv s, thus making commercial distribution and storage difficult.

In order to maintain the parity, stability ahd the therapeutic activity, the -compositions ^' Of this invention, comprisin CP and/or other CB2 receptor selective agonists are stabilized by addition of an antioxidant and/or free-radical scavenger. As used herein, term "stable" means that the quantitative composition does not significantly change over the time, during- the entire shelf-life of the composition, namely for at least 3 months, advantageously for at least 6 months, more advantageously for at least 12 months, even more advantageously for at least 24 months, ^■ under standard conditions, in particular at a temperature ranging: for 20°G to 4G°C :and relative humidity ranging for 3-0% to 75%. In particular, caryophyllene oxide level is less than 5% by weight, based on the total weight on die composition, during the entire shelf Hi of the composition, in the present invention, the composition is advantageously stable during 6 months to 1 year or during I year to 2 years under standard conditions. In some embodiments, compositions comprising BC ^' P and/or other CB2 receptor selective agonists and furthe comprisin an antioxidant a free-radical scavenger or a combination of a antioxidant and a free-radical scavenger have an extended sheli-iife, In some embodiments, the stable or stabilized compositions have the property to loose less than about 5% of the original compound when stored at room temperature from - about one year to about two years, in some embodiments, the stable or stabilized compositions have the property to loose less than about 10% of the original compound when stored at room temperature from, about one year to about two years. In some embodiments, the stable or stabilized compositions have the property to loose less than about 4% Of die original compound when stored at room temperature from about, One year to about two years. In some embodiments, the stable or stabilized compositions have the property to loose less than about 3% of the original compound when stored at room temperature from, about one year to about two years. I some embodiments, the stable or stabilized compositions have the property to loose less than about 2% of the original compound whe stored at room- temperature from about one year to about two years. I some embodiments, the stable or stabilized compositions have the property to loose less than abou 1% of the original compound whe stored at room temperature from about one year to about two years, in some embodiments, the stable or stabilized compositions have the property to loose from about 5% to about 10% of the original compound when stored at room temperature from about one year to about two years. In some embodiments, the stable or stabilized compositions have the property' to loose from about .1% to about 5% of the original, compound- when, stored at. room, temperature irom- a ut one year to aboiit two years. One of the problems related to the use of eannahinoids, in general, and CB2 receptor agonists, In particular, is their low bioavailability. Thus, tor example, oral THC- is onl 4% to 12% hioavaiiahie and its absorption is highly variable (McGilveray LJ,, Pain Res- anag. 2005 Aritumn; 10 Soppl A; 15A-22A). The same is true for the oral bioavailability of BCP, a C 2 selective agonist (U.S. Patent Application 20.15/0051299 and PCI Application 2013/1-40342, which are incorporated herein is their entireties).

It should be appreciated that the reasons responsible for low bioavailability via oral route can be due to poor aqueous solubility and/or poor - chemical stability in the alkaline pH of the gastrointestinal tract.

This is wh much effort has been in vested in the improvement of the cannabinoids* oral bioavailability

For -example, current .medications rising CEO request- high CBD amounts pe patient. Echo Pharmaceuticals Ltd has developed a drug delivery technology Alitra™ in which the drug- is formulated i-n a solid composition (granulates) to improve absorption and .distribution of compounds with low water solubility. For example, a drag based on CBD was developed (Arvisol®) with 30% bioavailability improvemen

Similarly, among the main disadvantages of currently available Λ-tetrahydrocammbinol (THC) formulations are dosing difficulties due to poo pharmacokinetic characteristics. Namisol® is a novel THC A-litra™ formulation, designed to improve THC absorption ( lumper ^' s L,E>, Br J Clin Pharmacol. 2012 Jul 74(1); 42-53.}. No such research has been carried ut on C82 receptor modulators, o CB2 receptor selective agonists in general or on BCP and liquid formulations in particular.

The composition of this disclosure is based on a formulation of the self-emulsifying drag: delivery system (SEDDS) type. The SEDDS technology is based on isotropic mixtures of oils. Surfactants, solvents .and eo-soivents/surfactants, which form- fine relatively stable oil--in-wai;er (o/w) emulsions upon aqueous- dilution owing to the gentle agitation of the gastrointestinal fluids. In this ease, there- is no granulate, but rathe liquid .compositions winch can be orally administered in sot or hard gelatin, capsules. A large number of composition alternatives have been explored (see Examples 1-1 Ijijn order to develop the most suitable- composition for oral delivery of CB2 receptor agonists in general and BCP in particular. Example 1, for example, shows a SEEDS composition that is efficient for oral administration.

A liquid composition tor oral delivery is described in Example 12.

Studies have been carried ou with water-diluted SEDDS compositions on mice (see Example 13). In. some embodiments, the composition is stabilized by addition to t e: composition of an antioxidant and/or free -radical scavenger. The stabilization of the composition can be necessary because of the ptoneuess of the C B.2 receptor modulators and CB2 receptor agonists to oxidation and can be achieved by addition to the composition of an antioxidant or free-radical scavenger. Antioxidant or free-radical can. also potentiate the therapeutic effect of CB2 receptor modulators and CB2 receptor agonists.

In some enrhodiroents, there is provided a composition formulated as a stable self- emulsifying drug delivery system (.SEDDS) comprising at least one oil, at least one surfactant HLB<9, at least one surfactant HLB> , at least one co-surfactant,, at least one antioxidant, and/or free-radical scavenger; at least one CB2 receptor selective or highly selective agonist and optionally at least one antipsychotic agent.

The role of CB2 receptor selective agonists, in general, and BCP, in particular, io the treatment of schizophrenia, has not previously been studied,

i 0 The effec of BCP in various compositions and modes of administration in murine model of schizophrenia, produced by administration of the N-methyl-D-aspailic acid (NMDA) antagonist, phenylcyclidine (PCI ⁵ ) has been described in U.S. Patent Application 2015/0051299 and PCX Application 2013/140342 (.incorporated herein in their entireties; description of EXAMPLE 151L '"Postnatal mduction of schizophrenia (days 3- 3.5) followed by treatment of I S adolescent mice with BCP (postnatal days 43-61) and FIGS. 14A-14E ^' show results demonstrating thai BCP treatment at adolescence reversed the effect of PCP on ambulation but did not affect body weight; line graph of body weight at PND 40-68 (14A), bar graph of female and male body weight at PMD63 (.14B) _S line graph of male ambulation at PND 63 (14D), _: line graph of female ambulation at PND 63 and line graph of male and female ambulation at PND ^• 0 63").

According to some aspects, tftere is provided a composition comprising beta- caryopfiy!lene (BCP) and seif-entulsifying vehicle for use in treating schi¾op renia.

According to some aspects, there is also provided the use of beta-caryoph llene (BCP) and seli-emnlsifying vehicle in the manufaciure of a medicament for treating schizophrenia in a IS subject in need thereof.

In some embodirnents, such a composition is formulated for administration t a human Subject, in some em odiments, siich a com osition i foniiulated for administration to a non- human animal subject.

According to softie aspects of the invention, there is also provided a method for treating iO schizophrenia in a subject in need thereof, the method comprising administering a pharmaceuticaily-effective amount of ^' beta-caryoph llene (BCP) to a subject in need thereof I some embodiments, the subject is a human subject. In some embodiments, the subject is a non- hurnan animal.

The efficacy of the methods and compositions according to the teachings herein are demonstrated in the experimental section .herein below,

According to some embodiments, the compositions and methods of treatments disclosed herein are useful for treating one or more of paranoid schizophrenia, disorganized schizophrenia, undifferentiated schizophrenia, catatonic schizophrenia, and residual: schizophrenia.

In some embodiments, the compositions and methods of treatments disclosed, herein are useiul in the treatment oiVnegaiive symptom of schizophrenia (according to The Diagnostic and Statistical Manual of Mental Disorders (DS )). In some embodiments, the compositions and methods of txeatments disclosed herein are useful in the treatment of a positive symptom of schizophrenia.

In some embodiments, the composition and methods of treatments disclosed herein are useful i the treatment of another symptom of schizophrenia (e.g. cognitive sy mptoms).

The duration of treatment according to the .method of treating schizophrenia according to aspect of the invention is any suitable duration as determined by a treatin health-care professional, typically a psychiatric doctor.

The CB2 receptor agonist (or specifically BCP) regimen of administration and the unit dosage administered to a mental disorder patient in need thereof can depend on the mode of administration, the efficiency of the composition and tire mental disorder to be treated.

Thus, for example, injectable, nasal and transdermal compositions tend t need lower dosages- than some oral compositions. Also,, some oral compositions (like the self-emul ify ng composition detailed in Example I and Example 22) surprisingly require dosages comparabl or lower to intraperitoneal injectable ^' compositions (for example, see comparison between the effects, of BCP in the open field test after intraperitoneal injection vs. gavage administration of self-emulsifying composition in Example 1). The results of intraperitoneal injectio are .described >in Example -.15ΪΪ . nd Figure 14E in U.S. Patent Application 2015/0051299 and PCX Application 2013/140342 to be compared with: the results (in Figure 2 of this disclosure) of gavage administration in SE DS composition as described m Example .1. of this disclosure (Description of EXAMPLE 1511. ''Postnatal induction of schizophrenia (days 3- 15) followed by treatment of adolescent mice with BCP (postnatal days 43-61 ) and FIGS. 14A-I4E show ^■ results demonstrating that BCP treatment at adolescence reversed the effect of PCP on ^' ambulation- but did not affect bod weight: line graph of body weight at PND 40-68 (14A), ar graph of female and male body weight at PND63 (14B), line graph of male ambulation at PHD 63 (14D), fine graph of female ^■ ambul tion at PND 63 and line graph of m le and female arrtbulation at PND 5 63")-

In addition. Example I and Figures 1 and 3 A of this disclosure show that n other tests, i.e. forced-swim test and social interaction test, BCP in self-emulsifying composition is als orally active at about the same dosage (5 nig/kg) as in the open field test (Example I and Figure

2 of this disclosure), Collectively, these results show that surprisingly BCP in SEDDS seif- 10 emulsifying composition is orally active at about the same dosage as intraperitoneal injection.

In some embodiments, some SEDDS compositions surprisingly at much more effective than other SEDDS compositions (like in Example 16 V-01 is eff ective whereas Λ -02 and V-

03 are less effective). Collectively, these results show that surprisingly BCP i the specific SEDDS- .self-emulsifying composition described i Example 1 is orally active at about the same

I S dosage as iniiaperiton.eal injection.

Also, some oral compositions (like the self-emulsifying composition detailed iri Example I ) surprisingly are much more effective than other oral compositions (like Example 1 — oil composition and compare between the effects of BCP in the forced swim test after gavage administration of self-emulsifying composition in Example 1 and Figure 1 versus the results after 10 gavage administration of oil compositio in Example 1.4 and Figure 4 in th s application).

In some embodiments, there is provided a highly effective self-emulsifying composition of the present disclosure for the treatmen of a mental disease in a patient in need thereof wherein the administration of an oral dose of said self-emulsifying composition (see Example I) produces a therapeutic effect similar to the intraperitoneal -administration of the same dose (as IS above, Example 1511 and Figure I4E in U.S. Patent Application 2015/0051299 and PCX Application 2013/140342) and a much more effective therapeutic -effect than non-seif- einuisifying oral compositions such as oil compositions (Example 1 ).

METHOD

Preparation of diluted oral SHOPS vehicle wife BCP for adrnkmiration by gavage,..

Sterile double-distilled water (D W) was warmed for 10 mm in a pre-watmed tbsrmobath (3 - !5 38 ^' C) _r ^' The SEDDS vehicle of the oral composition of Example 1 was wanned up separately to 35-38 C for 10 mm. In order to prepare BCP (5 mg/.tnlj for a final dose of 10 rng/kg, BC (5 mg) was added directly into the vehicle (1 till) and vortexed for 1 to obtain the oral composition. Then the wanned sterile DDW (4 ml) at 35-38 C was added at a ratio of 1:5 oral composition: DDW dilution and the diluted composition was vortexed for 1 min. ^" in order to 10 prepare BCP for a final dose of 5 mg kg, 500 μί of BCP at 5 rng/nil were diluted with 500 μ] SEDDS vehicle (1 :2 dilution). Then the wa med sterile DDW (4 nil) at 35-38 ^" C was -added -at a ratio of 1 ;5 oral composition. DDW dilution, arid the diluted composition was vortexed for 1 min.

BCP (5 rng/fcg or 10 ag/kg in diluted self-emulsifying vehicle (Example I)) was 15 administered to adolescent mice (10 ui/g) by gavage twice a week (on Sunda and Wednesday) for 3 weeks (PND 43-62), a total of 6 injections. Control group and PCP~.indo.ced group received by gavage the oral formulation solution without the drug. After the final BCP injection,, mice were tested in. the open field test (PND 64-66). forced-swimming test (PHD 70-71 ) and. social interaction, test (P D 88-89),

Faroed-swimming test

Training was conducted for 6 min a day efore the test Each mouse was placed into a transparent glass cylinder filled with fresh water at 25 ^C C. On the test day, the total duration/i equency of immobility and climbing wa counted every 2 minutes for 6 minutes. An increase in frequency of climbing serves as a inde of increased despair.

Open fie id test

Each mouse was placed into the center of a clear open Plexsglas Chamber (40 era * 32 cm * 30 cm) which its floor was divided to squares of 4 cm. X 5 em. Testing was performed i the presence of a bright white light. Ambulation behavior was manually counted for 8 mm and data were collected in 2 mitt intervals.

Social interaction test in a novel environment

Each mouse was placed, in a novel cage together with a ncmaggressive intruder mouse, o the same species, same- sex and a similar age. The interaction between the two- mice was recorded for 10 minutes with EthdVision. software (Moldus), Social interaction was defined by contact between the mice (tracking nose point). Reduced duration of contact behavior indicates on impairment in social interaction.

Results

PIG. 1 shows that oral treatment with 5 or. 1.0 mg/l g BCP in SEDDS oral formulation: at adolescence reversed the effect of FCP on. mice in th forced-swim test. These results show tha BCP acts orally and that the SEDDS composition used is efficient for oral administration. These ^• results show that BCP in oral SEDDS composition is effective in reversing depression-like behavior, supporting, its use as a pharmaceutical drug for the treatment of mental diseases i which depression is one of the syinpioms (like for example bi-polar/mania-depressive disorder, depression., anxiety, ADHD, Toorette syndrome, depression associated with neurodegenerative diseases, depression that leads to metabolic diseases). FIG. 2 of this disclosure shows that oral treatment with 5 mg/kg BCP in SEDDS oral formulation- at adolescence reversed die eiTect of PCP on activit of mice in the open field tes These results sho that BCP acts orally and that the composition used is efficient for oral administration. Comparison of the results in FIG 2 in this disclosure with the results in Figures 14C-E in the U.S. Patent Application No. US 2015-0051299, shows that BCP in oral SEDDS composition is effective at the same dose as it has been shown for i.p. route of .administration,, which is surprisingly good.

FIGS. A-B show that oral treatment with 5 mg/kg BCP in SEDDS oral compositio at adolescence reversed the eiTect of PCP on mice ½ the social interaction test (3A) hut did not affect their body weight (3-B). These results show that BCP acts orally and that the composition used is efficient for oral administration. These results show that BCP ^' in oral SEDDS composition is effective in reversing deficits i social interaction.

'TREATMENT OF ADOLESCENT MICE WITH BCP oil

METHODS

Preparation of diluted oral formulation- of BCP for administration by gavag

BCF was dilated in canola oil.

BCP (10 mg ^' kg diluted in canola oil) was administered to adolescent mice (PND 4362) by gavage twice a week (on Sunday and Wednesday) for 3 weeks, a. total of gavages. Control group and PCP-iiKluced group received by gavage the oil vehicle.- After the final gavage, mice were tested in the open field test (PND 59), forced-swiraming test (PND 83) and social interaction test (PHD 88-89 ^' ) ^' .

Forced'Swimming test

Training was conducted for 6 min a day before the test. Each mouse was placed into a transparent glass cylinder filled with fresh water at 25*C. On the test day, the total dmation/frequency of immobility and climbing was counted every 2 minutes for .6 minutes. An increased immobility is an index of learning and habituation,, therefore a positive behavioral adaptation With- a stressful condition. Results

PIG _* 4 sho s that oral treatment with ! 0 tng kg BCP in. oil composition did not, reverse the -effect of 5 tng/kg ^' POP OR the frequency of immobility of mice in the forced swim test. These results show that BCP in SEDDS composition is effective while BCP in oil was ineffective on reversing the frequency of climbing hi the forced-swim test. These results sho w that BCP in SEDDS oral composition surprisingly work much better than other oral compositions.
