Abstract:
The preparation of the present invention was found to be effective for the majority of patients diagnosed with autism. In patients characterized by delayed language development and non-expressive/non-emotional communication patterns, the preparation of the invention was found to be more effective than in patients that were diagnosed with autism without delayed language development and with expressive/emotional communication patterns, even though all patients consumed the preparation for a similar duration. Specific analysis for the type and quality of the improvement detected within the group of patients characterized by delayed language development and non-expressive/non-emotional communication patterns revealed that the majority of patients improved in various communication abilities: speech, language, conversation, and social play.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to phospholipid preparations effective in improving communication abilities in subjects suffering from communication impairments/difficulties. 
       BACKGROUND OF THE INVENTION 
       [0002]    Communication is giving, receiving or exchanging ideas, information, signals or messages, enabling individuals or groups to persuade, to seek information, to give information or to express emotions. This broad definition includes body-language, skills of speaking and writing. 
         [0003]    Communication impairments/difficulties are developmental or acquired impairments. The American Speech-Language-Hearing Association (ASHA) describes communication disorders more specifically, as impacting one&#39;s ability to “receive, send, process, and comprehend concepts or verbal, nonverbal and graphic symbol systems.” Communication impairments can partially or totally prevent communication. 
         [0004]    Communication impairments may include, but are not limited to problems related to speech, language and auditory processing or social pragmatic communication. The last represent difficulties that influence the use of verbal and nonverbal communication in naturalistic contexts, which affects the development of social relationships and discourse comprehension. 
         [0005]    Communication impairments are present in several disorders including, neurological disorders (e.g., epilepsy, aphasia, and brain injury/trauma); emotional or psychiatric disorders (e.g., generalized anxiety disorder, agoraphobia, social anxiety disorder, phobias, panic disorder, post-traumatic stress disorder, and selective mutism); personality disorders (e.g., schizophrenia and obsessive-compulsive disorder); developmental disorders (e.g., autism, Asperger syndrome, pervasive developmental disorder, childhood disintegrative disorder, Rett syndrome, and mental retardation); and speech disorders. 
         [0006]    Autism spectrum disorder (ASD) covers a set of developmental disabilities that can cause significant social, communication, and behavioral challenges. ASD patients suffer from social communication disorder that is also characterized by restricted or repetitive pattern of behavior that causes significant functional impairment and distress for affected individuals and their caregivers. The terms Autism and ASD are herein interchangeably used. 
         [0007]    ASD may be categorized on the basis of language development. Delays and/or abnormalities in language functioning are evident in some individuals with Autism while in others (such as Asperger patients) there is no clinically significant general delay in language although atypical language is often present as qualitative abnormalities such as: rate, volume, prosody, pragmatics, or frequency of speech production. 
         [0008]    Another way to classify ASD is on the basis of communication patterns. Several studies have revealed that some individuals with autism (such as Asperger patients) have expressive/emotional communication patterns, whereas others use non-expressive/non-emotional communication patterns. Interestingly there is an association between the presentation of communication patterns and language development. Most ASD individuals without delay in language development present expressive/emotional communication patterns; whereas most ASD individuals suffering from a delay in language development also present non-expressive/non-emotional communication patterns. 
         [0009]    To the best of our knowledge, today there are no approved medications indicated to cure, prevent or manage communication disorders. Looking specifically at ASD, only 2 atypical antipsychotics, Risperidone and Aripiprazole, are approved by the US Food and Drug Administration (FDA) for treatment of significant irritability (aggression toward others, deliberate self-injuriousness, temper tantrums, and labile moods) associated with ASD. These medical interventions benefit challenging behaviors however, they were not reported to improve verbal or non-verbal communication in ASD patients. Moreover, they have significant side effects including weight gain, sedation, and extrapyramidal effects. 
         [0010]    Although medications are not correlated with a beneficial effect on communication patterns, there is increasing evidence that intervention approaches designed to enhance the communication and language development of children communication impairments can improve communication skills and abilities. 
         [0011]    Glycerophospholipids, also referred to as phospholipids are key components of the lipid bilayer of cells, and are involved in cell metabolism and signaling. The hydroxyl groups of the glycerol backbone of phospholipids are substituted by a hydrophilic phosphate head and hydrophobic tail composed of non-polar fatty acids. Glycerophospholipids may be subdivided into distinct classes, based on the nature of the polar head group such as for example: phosphatidylcholine (also known as PC or lecithin), phosphatidylethanolamine (PE), and phosphatidylserine (PS). In addition to serving as a primary component of cellular membranes and binding sites for intracellular and intercellular proteins, some glycerophospholipids, such as phosphatidylinositols and phosphatidic acids are either precursors of, or are themselves, membrane-derived second messengers. Studies have shown that PS and PC enhance neuronal membrane function and improve memory skills. PS was found to have a beneficial effect in ADHD, depression, and chronic stress. In addition, PC was found to reduce emotional symptoms of premenstrual syndrome. 
         [0012]    Apparently, the origin of the phospholipids and their fatty acid content influence their activity. For example, the bio-functionality of soybean PS in the improvement of cognitive function has been shown to be different from that of other types of PS (see, WO 2005/037848). In addition, it was demonstrated that different ratios of specific fatty acids conjugated to PS can influence the efficacy of the PS in improving cognitive functions in elderly subjects with impaired cognitive performance (see, WO 2009/156991). 
         [0013]    It is thus beneficial to apply the appropriate type of PS preparation for the specific indication.

         [0067]    Wherein X represents a moiety selected from serine, choline, ethanolamine, inositol, glycerol and hydrogen, and R1 and R2, which may be identical or different, independently represent hydrogen or an acyl group, wherein the acyl group is selected from saturated, mono-unsaturated or poly-unsaturated acyl groups (PUFA). The sn-1 and sn-2 positions as used herein and as indicated in above formula, refer to the respective carbon atoms on the glycerol backbone wherein R 1  and R 2 , are hydrogen or acyl groups substituted on the corresponding position. 
         [0068]    The term “lysophosphatidic acid” is used herein when X represents hydrogen and one of R1 or R2 is Hydrogen as well. 
         [0069]    As described herein, the terms “substituted,” “conjugated,”, and “attached” are used interchangeably and should be understood to encompass a fatty acid acyl covalently attached to the glycerophospholipid backbone of a phospholipid of the invention. As noted above, the fatty acid may be attached to the sn-1 and/or sn-2 positions. 
         [0070]    As used herein, the term “fatty acid” should be understood to encompass a carboxylic acid with a long unbranched aliphatic tail (chain), which is either saturated, or unsaturated having one unsaturated bond (mono-unsaturated fatty acids) or two or more unsaturated bonds (poly-unsaturated fatty acids). When referring to a “fatty acid acyl” it should be understood to encompass an —C(═O)—R radical wherein R is a long unbranched aliphatic tail, which is either saturated or unsaturated having one unsaturated bond (mono-unsaturated fatty acids) or two or more unsaturated bonds (poly-unsaturated fatty acids). 
         [0071]    As used herein, the term ω-X, Omega-X, n-X (X denotes a number), are interchangeably used and should be understood to denote the carbon atom furthest from the carboxyl group of a fatty acid. 
         [0072]    Non-limiting examples of saturated fatty acids include: Butyric acid (Butanoic acid, C4:0), Caproic acid (Hexanoic acid, C6:0), Caprylic acid (Octanoic acid, C8:0), Capric acid (Decanoic acid, C10:0), Lauric acid (Dodecanoic acid, C12:0), Myristic acid (Tetradecanoic acid, C14:0), Palmitic acid (Hexadecanoic acid, C16:0), Stearic acid (Octadecanoic acid, C18:0), Arachidic acid (Eicosanoic acid, C20:0), Behenic acid (Docosanoic acid C22:0). 
         [0073]    Non-limiting examples of unsaturated fatty acids include: Myristoleic acid (C14:1, ω-5), Palmitoleic acid (C16:1, ω-7), Oleic acid (C18:1, ω-9), Linoleic acid (C18:2, ω-6), Linolenic acid (C18:3) [Alpha-linolenic acid (C18:3, ω-3), Gamma-linolenic acid (C18:3, ω-6)], Eicosenoic acid (C20:1, ω-9), Arachidonic acid (C20:4, ω-6), Eicosapentaenoic acid (C20:5, ω-3), Erucic acid (C22:1, ω-9), Docosapentanoic acid (C22:5, ω-3) and Docosahexaenoic acid (C22:6, ω-3), Nervonic acid (C24:1, ω-9). 
         [0074]    The term a “[fatty acid] conjugated to phospholipid,” should be understood to encompass a phospholipid wherein a fatty acid acyl is conjugated at position sn-1 and/or position sn-2 of the phospholipid backbone (through the glycerol oxygen atom). In one embodiment, a fatty acid is conjugated at position sn-1, and position sn-2 is either unsubstituted (e.g. having a hydrogen atom on the glycerol oxygen) or substituted with an acyl group selected from saturated, mono-unsaturated and polyunsaturated fatty acids, which may be the same or different from the substitution on position sn-1. In another embodiment, a fatty acid is conjugated at position sn-2 and position sn-1 is either unsubstituted (e.g. having a hydrogen atom on the glycerol oxygen) or substituted with an acyl group selected from saturated, mono-unsaturated and polyunsaturated fatty acids, which may be the same or different from the substitution on position sn-2. 
         [0075]    The term phosphatidylserine is often also referred to in the literature as serine glycerophospholipid, phosphatidyl serine, and PS. 
         [0076]    The term phosphatidylcholine is often also referred to in the literature as Choline glycerophospholipid, phosphatidyl choline, and PC. 
         [0077]    A preparation of the invention may also be administered in conjunction with other compounds, including, but not limited to folic acid, vitamins, minerals, amino acids, nucleotides, antioxidants and so forth. 
         [0078]    It will be appreciated that a composition (whether pharmaceutical, nutraceutical, nutritional, medical food, etc.) or product (e.g. functional food) of the invention may be combined with other treatment methods known in the art. Thus, treatment of communication impairment (e.g. Autism) using a composition or product of the invention may optionally be combined with conventional therapies for communication impairment such as but not limited to: stimulants, anti-stimulants, methylphenidate, dextroamphetamine clonidine, guanfacine, risperidone, haloperidol, olanzapine, thioridazine, fluoxetine, sertraline, lithium, lorazepam carbamazepine, valproic acid. 
         [0079]    Disclosed and described, it is to be understood that this invention is not limited to the particular examples, process steps, and materials disclosed herein as such process steps and materials may vary somewhat. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only and not intended to be limiting since the scope of the present invention will be limited only by the appended claims and equivalents thereof. 
         [0080]    It must be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents unless the content clearly dictates otherwise. 
         [0081]    Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising,” will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. 
         [0082]    A preparation as described herein may be optionally prepared through enzymatic, chemical or molecular biology methods. Briefly, a phospholipid mixture can be enriched with the required fatty acids (e.g. EPA, Palmitic acid, DHA, oleic acid, linoleic acid) by enzymatic processes, e.g. enrichment of a natural phospholipid with specific fatty acids by enzymatic transesterification/esterification. Another pathway to acquire the preparation is to obtain a phospholipid source which is naturally rich in the required fatty acids, such as marine-derived lecithin (e.g. krill, fish, algae, and squid) or eggs phospholipids. Usually, In order to obtain the requested ratio between the different phospholipids in the mixture transformation of the phospholipid head group to serine (using PLD enzymes) is required to obtain PS. Such methods have been described in WO 2005/038037. Alternatively, the phospholipid mixture, according to at least some embodiments of the present invention can be prepared by GMO (genetically modified organisms)/biotechnology methods, for example, providing phospholipids-producing organisms with the required fatty acids to obtain the different phospholipids conjugates. 
         [0083]    According to another embodiment of the present invention, the preparation is preferably prepared from a natural, synthetic or semi-synthetic source or any combinations thereof. In an embodiment of the present invention, the natural source is derived from any one of plant (such as for example soy and algae), non-mammalian animal (such as for example krill, fish (such as for example Herring and blue Whiting), or microorganism (such as for example bacteria) source or any combinations thereof. In yet a further embodiment, the production of the lipid preparation involves an enzymatic catalysis.

         [0084]    Purpose: This method is used to determine the phospholipid content by weight in the preparation. 
         [0085]    Instruments: Bruker Avance III 600 MHz with automatic sample changer and cQNP probe head. Bruker Avance 300 MHz with automatic sample changer and BBI probe head. For the quantification of phospholipids in the preparation of the invention (powder form) approximately 300 mg of the test substance and 20 mg of internal standard TPP (triphenylphosphate) is dissolved in 1.5 ml CDC13, 3 ml methanol and 3 ml aqueous Cs-EDTA solution (0.2 m, pH 7.5). After 15 minutes of shaking, the organic layer is separated by centrifugation and measured with 31P-NMR. The integrated signals of the test substance and of the internal standard TPP (triphenylphosphate) are used for calculation. The ratio of integrals corresponds to the molar ratio of the compared substances. For calculation software Microsoft Excel 14.0 is used.

         [0100]    Procedure:
   Sample solution preparation: Accurately weight 500 mg of the sample into a 20 ml vial with ground stopper. Add 10 ml Chloroform: Methanol solution and shake vigorously for 2-3 minutes.   Phospholipids purification: Perform test in duplicate. Perform blank determination by developing an unloaded plate (no sample applied to the plate). Sample silica from an area corresponding to the area of the sample followed by methylation as described above. Apply an even thin band of 120 μl sample solution on TLC plate, 1 cm above the plate bottom, leaving a 3 cm margin on each side. At one of the margins, apply PS/PC mix standard solution of approximately 5 μl, spot wise by means of a disposable capillary. Add 45 ml of di-isopropyl ether to the 20×10 mm Glass TLC chamber. Saturate the chamber for 15-20 minutes. Develop TLC plate up to about 90 mm mark. Dry the plate in fume hood under air at room temperature for about 10 minutes. Repeat the previous two steps once more using the same chamber. Add 45 ml of developing solution to the 20×10 mm Glass TLC chamber. Saturate the chamber for 15-20 minutes. Develop TLC plate up to about 80 mm mark. Dry the plate in fume hood under a current of air at room temperature for about 10 minutes. Spray the TLC plate evenly with Primuline solution and dry under a current of air at room temperature for about 10 minutes. Place the plate under UV lamp at 365 nm to observe the bands. Identify the corresponding bands using spots of PS mix reference standard and scrub the bands in-to a 20 ml glass vial with ground stopper.   Methylation: To the 20 ml vials containing scrubbed silica add 2 ml Toluene. Then add 4 ml of Sodium methoxide solution. Shake for 15 minutes at 50° C. Then add 200 μl of Acetic acid and 4 ml of purified water, shake vigorously for 1 minute. Add 2 ml of Hexane and shake vigorously for 30 seconds. Transfer only the upper organic layer to a 20 ml bottle. Again add 2 ml of Hexane and shake vigorously for 30 seconds. Transfer only the upper organic layer to the same 20 ml bottle. Combine organic phases and dry over 0.5 grams Sodium sulfate. Filter through a 0.2 micron filter. Evaporate hexane under a nitrogen stream, until a volume of about 0.5 ml is reached. Analyze the sample by Gas Chromatography.

         [0000]    where, t1and t2are the retention times of the two components and W1 and W2 are the corresponding widths at half-height of the peaks.
   Next, inject sample from blank TLC plate (TLC blank). If there are peaks observed in the TLC blank chromatogram (except the solvent peak), they must be subtracted from the chromatogram of the sample. Finally, inject Samples.   
 
         [0107]    Calculation: Calculate the area percentage of a fatty acid component in sample by the formula: % FA=AreaFA/AreaTot, where AreaFA is the area of the peak response obtained for an individual fatty acid methyl ester and AreaTot is the sum of the peak areas of all of the peaks, corresponding to fatty acids methyl esters. Report the results indicating two digits after decimal point. Relative standard deviation between the replicates should not exceed 5%.

       [0109]    Preparation of phospholipid composition: Lipid preparations were prepared as follows: marine lecithin produced by an extraction process from biomass derived from krill was dissolved in organic solvents and allowed to react with an aqueous solution containing L-serine, CaCl2, phospholipase D (PLD), and acetate buffer. Following the trans-phosphatidylation reaction, the resulting mixture that contained PS, PC, PA, and LPA was purified by removal of the water phase, evaporation of the organic solvents, and further purification stages. The resulting powder mainly contained EPA, Palmitic acid, DHA, oleic acid, and linoleic acid bound to the different phospholipids.

         [0110]    Study design: The effect of the phospholipid composition on autistic patients was evaluated in 19 children (3 females and 16 males), 2-17 years of age, who were diagnosed with autism. All study patients received a daily dose of 1-4 capsules of the phospholipid composition for at least 3 months, with or without concomitant medication for the management of Autism. 
         [0111]    The effect on the autistic symptoms was evaluated via electronic health record reviews and is described in Table 2. Of the study patients, 6 were classified as suffering from Autism without language delay and with expressive/emotional communication patterns (subclass 1). 13 were classified as suffering from delay in language development and non-expressive/non-emotional communication patterns (subclass 2). All the participants received the phospholipid preparation. The dosage and the duration of the administration are described in table 2. 
         [0112]    Results: In general, as demonstrated in Table 2, 10 out of the 19 patients evaluated in the study demonstrated an improvement in autistic symptoms during the study period (e.g. patient No. 4: “general improvement”, patient No 12: “improved speech”). Interestingly, all the improvements were observed in the group of patients who suffered from language delay and had non-expressive/non-emotional communication patterns (subclass 2). In this group, 10 patients (No. 2, 3, 4, 5, 8, 9, 10, 11, 12, 13) demonstrated an improvement in autistic symptoms during the study period. In the group without language delay and with expressive/emotional communication patterns (subclass 1; 6 patients) no significant improvements were detected (No. 14, 15, 16, 17, 18, 19). 
         [0113]    Of the patients who improved, 6 patients (No. 2, 5, 8, 9, 10, 12) demonstrated an improvement in their communication abilities: patient No. 2 made progress in speech, patient No. 5 talked more, patient No. 8 followed conversation well, patient No. 9 improved his social play, patient No. 10 became more conversational, and patient No. 12 improved his speech.
