CROSS REFERENCE TO RELATED APPLICATIONS

[001] This application claims the benefit of priority under 35 USC §119(e) of U.S. Provisional Patent Application No. 63/335,978, filed April 28, 2022, entitled “COMPOSITION FOR USE IN THE TREATMENT OF A DISEASE”, the contents of which are all incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

[002] The invention relates generally to the field of compositions comprising one or more trehalose conjugates and is directed to methods of using the same such as for treating a disease or a disorder in a subject.

BACKGROUND

[003] Acute pancreatitis (AP) is a common disease in gastroenterology with an increasing global incidence, where it accounts for about 2% of all hospitalized patients. AP is a complex inflammatory syndrome that results from many etiologies where gallstones, alcohol and ERCP are the leading causes. About 20% of patients who experienced first AP-attack will develop recurrent attacks (RAP) and approximately one third of the latter continue to end-stage chronic pancreatitis (CP). Despite the great advances in medicine, the worldwide mortality rate among AP patients remained high, imposing an important burden on the health care system. It is widely accepted that excessive stimulation of the pancreas or direct destructive insults obstruct the outflow of zymogen granules, where they are proteolytically activated in the acinar cells by lysosomal enzymes mainly cathepsin B and eventually causing acute cell injury. This adverse reaction is further exacerbated by neutrophilic enzymes and transcription factors, which lead to the production of various proinflammatory cytokines, including tumor necrosis factor (TNF)-a, interleukin (IL)-l, IL-6, and IL-8, along conversion of trypsinogen into trypsin- a phenomenon also referred to as auto-digestion. Moreover, the proinflammatory stimuli upregulates cyclooxygenase (C0X)-2, a key enzyme responsible for the generation of prostaglandins, leukotrienes, and thromboxanes.

[004] In light of the vague characterization of the mechanistic pathways responsible for AP, the treatment options targeting a specific underlying cause remain elusive and the current therapy relies mainly on pain killers and hydration, where opioids being the most frequently prescribed analgesics for pain relief of patients with AP. As AP is secondary to pancreatic parenchymal inflammation, non-steroidal anti-inflammatory drugs (NSAIDs) are also often used. Previous studies have highlighted the keen involvement of heparanase in the pathogenesis of inflammatory diseases including AP. Specifically, it has been evidenced that pancreatic heparanase expression and activity are significantly increased following cerulein-induced AP. Moreover, pancreas edema and inflammation, as well as the induction of cytokines and signaling molecules following cerulein administration were attenuated markedly by PG545 and SST0001, selective heparanase inhibitors, implying that heparanase plays a significant role in AP. Notably, all the above features appear even more pronounced in transgenic mice over expressing heparanase, suggesting that these mice can be utilized as a sensitive model system to reveal the molecular mechanism by which heparanase functions in AP. Therefore, there is an ongoing need to develop novel medications for specific and efficient treatment of AP.

[005] Inflammatory brain disease, also referred to as inflammatory disease of the central nervous system (CNS), is a condition where the brain and/or spinal cord become inflamed. Inflammation in the brain causes irritation and swelling of brain tissue or blood vessels and can lead to brain damage over the long term.

[006] Chronic brain inflammation leads to measurable brain shrinkage, especially in the areas associated with Alzheimer’s disease, the 6th leading cause of death. Chronic brain inflammation leads to mental fatigue, brain fog, and memory loss. Chronic brain inflammation has been linked to numerous neurological and psychiatric disorders, including depression, anxiety, substance abuse, schizophrenia, bipolar disorder, Alzheimer’s, and Parkinson’s. [007] Encephalitis is a rare form of acute brain inflammation that is usually caused by a viral or bacterial infection. Symptoms include fever, headache, seizures, stiff neck and back, and mental confusion. Encephalitis can cause brain damage and even death.

[008] Non-Steroidal Anti-inflammatory Drug (NSAID) are extensively used for the treatment of inflammation and pain. NSAIDs act by inhibiting Cyclooxygenase (COX)-l and/or COX-2 activity, thereby reducing intracellular synthesis of prostaglandins, being associated with inflammation and/or pain. However, most NSAIDs are not able to cross the blood brain barrier (BBB) in an amount sufficient for inducing a therapeutic effect. Therefore, there is an ongoing need to develop methods for enhancing BBB penetration of known NSAIDs, e.g., for use in the treatment of brain inflammation and for reducing COX activity within the brain.

[009] The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the figures.

General

[00110] As used herein, the terms “treatment” or “treating” of a disease, disorder, or condition encompasses alleviation of at least one symptom thereof, a reduction in the severity thereof, or inhibition of the progression thereof. Treatment need not mean that the disease, disorder, or condition is totally cured. To be an effective treatment, a useful composition herein needs only to reduce the severity of a disease, disorder, or condition, reduce the severity of symptoms associated therewith, or provide improvement to a patient or subject’s quality of life.

[00111] As used herein, the term “prevention” of a disease, disorder, or condition encompasses the delay, prevention, suppression, or inhibition of the onset of a disease, disorder, or condition. As used in accordance with the presently described subject matter, the term "prevention" relates to a process of prophylaxis in which a subject is exposed to the presently described active ingredients prior to the induction or onset of the disease/disorder process. This could be done where an individual has a genetic pedigree indicating a predisposition toward occurrence of the disease/disorder to be prevented. For example, this might be true of an individual whose ancestors show a predisposition toward certain types of inflammatory disorders.

[00112] The term "suppression" is used to describe a condition wherein the disease/disorder process has already begun but obvious symptoms of the condition have yet to be realized. Thus, the cells of an individual may have the disease/disorder, but no outside signs of the disease/disorder have yet been clinically recognized. In either case, the term prophylaxis can be applied to encompass both prevention and suppression.

[00113] Conversely, the term "treatment" refers to the clinical application of active agents to combat an already existing condition whose clinical presentation has already been realized in a patient.

[00114] In the discussion unless otherwise stated, adjectives such as “substantially” and “about” modifying a condition or relationship characteristic of a feature or features of an embodiment of the invention, are understood to mean that the condition or characteristic is defined to within tolerances that are acceptable for operation of the embodiment for an application for which it is intended. Unless otherwise indicated, the word “or” in the specification and claims is considered to be the inclusive “or” rather than the exclusive or, and indicates at least one of, or any combination of items it conjoins.

[00115] It should be understood that the terms “a” and “an” as used above and elsewhere herein refer to “one or more” of the enumerated components. It will be clear to one of ordinary skill in the art that the use of the singular includes the plural unless specifically stated otherwise. Therefore, the terms “a”, “an” and “at least one” are used interchangeably in this application.

[00116] For purposes of better understanding the present teachings and in no way limiting the scope of the teachings, unless otherwise indicated, all numbers expressing quantities, percentages or proportions, and other numerical values used in the specification and claims, are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

[00117] In the description and claims of the present application, each of the verbs, “comprise”, “include”, and “have” and conjugates thereof, are used to indicate that the object or objects of the verb are not necessarily a complete listing of components, elements or parts of the subject or subjects of the verb.

[00118] Other terms as used herein are meant to be defined by their well-known meanings in the art.

[00119] Unless specifically stated or obvious from context, as used herein, the term "or" is understood to be inclusive.

[00120] Throughout this specification and claims, the word “comprise” or variations such as “comprises” or “comprising” indicate the inclusion of any recited integer or group of integers but not the exclusion of any other integer or group of integers.

[00121] As used herein, the term “consists essentially of’ or variations such as “consist essentially of’ or “consisting essentially of’ as used throughout the specification and claims, indicate the inclusion of any recited integer or group of integers, and the optional inclusion of any recited integer or group of integers that do not materially change the basic or novel properties of the specified method, structure or composition.

[00122] As used herein, the terms "comprises", "comprising", "containing", "having" and the like can mean "includes", "including", and the like; "consisting essentially of or "consists essentially" likewise has the meaning ascribed in U.S. patent law and the term is open-ended, allowing for the presence of more than that which is recited so long as basic or novel characteristics of that which is recited is not changed by the presence of more than that which is recited, but excludes prior art embodiments. In one embodiment, the terms "comprises" "comprising", and "having" are/is interchangeable with "consisting".

[00123] Various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below find experimental support in the following examples.

EXAMPLES

Materials & Methods

[00124] Animals. Studies utilized wild type (WT) BALB/c mice and heparanase transgenic (Hpa-Tg) mice in which the human heparanase gene is driven by a constitutive P-actin promoter (19) in a BALB/c genetic background. Animals were fed standard mouse chow and tap water ad libitum. All experiments were approved and performed according to the Technion’s guidelines of the Committee for the Supervision of Animal Experiments.

[00125] Induction of acute pancreatitis. Mice were injected with either cerulein (intraperitoneally, 50 mg/kg, 5 times at 1 hour apart) (Sigma-Aldrich), or saline (0.9% NaCl) (control group). Additional groups of mice were pretreated with either Aspirin (250 mg/kg, SC) and Trehalose (2000 mg/kg, ip) alone or combined. Additional groups of animals were pre- and post-treated with Aspirlose (lOmg/mouse). In the next step, we examined the pancreato-protective effects of indomethacin and Diclofenac (16 and 32 mg/kg ip) alone or combined with Trehalose. Finally, we tested the effectivity of “Indose” and “Diclose” at various concentrations against AP. Mice were sacrificed 24 hours later, and serum samples and pancreatic tissue were collected for measurements of blood amylase and lipase levels, pancreatic index (pancreas/body weight ratio), and for histological analysis. Portion of pancreas tissues were also homogenized, and lysate samples were subjected to immunoblotting.

[00126] Light microscopy. Pancreatic tissue samples were fixed in 10% neutral -buffered formalin progressively dehydrated in graduated alcohol and embedded in paraffin. Five micron sections were stained with hematoxylin and eosin (H&E). [00127] Electron microscopy Tissue samples were stabilized with glutaraldehyde 2% and osmium tetroxide (OsO4) 4%, followed by dehydration in graded ethanol, embedding in commercially available resin media, and staining with uranyl acetate and lead nitrate to achieve better image contrast for further examination in JEOL 1011 transmission electron microscope.

[00128] Statistical analysis. Data are presented as mean of repeated measurements ± standard error (S.E.M). Comparison between two parametric groups was performed using the unpaired Student t test after testing for equality of variances. More than two paired groups were tested using the one-way analysis of variance (ANOVA) test for repeated measurements, followed by the Tukey post-hoc test for multiple comparisons.

[00131] Asprilose

[00132] The inventors studied various trehalose: aspirin ratios in order to obtain the desired mono-, and/or diester in an acceptable yield. Based on these experiments a trehalose: aspirin ratio of 2:1 has been chosen. The synthesis of asprilose has been performed as follows:

[00133] Aspirin (acetyl salicylic acid) (1.8 gr (10 mmole)), N,N - Dicyclohexylcarbodiimide ( 2.06 gr (10 mmole), 4-Dimethylaminopuridine ( 1.22 gr (10 mmole)), Hydroxybenotriazole ( 1.35 gr ( 50 mmole )) and Trehalose ( 6.84 gr (20 mmole)) were dissolved in Dimethylformamide (20 ml) and stirred for 1-10 hours at room temperature. Precipitated dicyclohexylurea was removed by filtration. Solvent was removed by evaporation (Rotavap). The resulting Asprilose (a mixture of mono and diester) was purified on a reverse phase silica gel C- 18 chromatography column, using a gradient of a mobile phase composed of a mixture of water and an organic water miscible solvent (e.g. methanol, ethanol, acetonitrile, ethyl acetate).

[00134] Chemical structures of the purified mono and diester was verified by LC-MS and NMR.

[00135] Diclose & Indose

[00136] Diclose and Indose have been synthesized according to a similar procedure, as described hereinbelow.

[00137] The reaction has been performed in a 100 ml three necked flask equipped with thermometer, magnetic stir and condenser with Nitrogen bubbler.

[00138] Indomethacin (3.57 gr (10 mmole) or 2.95 g Diclofena (lOmmol), has been added to the reaction flask, followed by addition of DCC (2.06 gr (10 mmole), 4-DIMAP (1.22 gr (10 mmole)), HOBT (1.35 gr (10 mmole)) and Trehalose ( 6.84 gr (20 mmole). Add DMF 25ml and stirred for 24 hours at room temperature. Precipitated dicyclohexylurea was removed by filtration and washed with 5 ml DMF. The solvent was removed by evaporation (Rotavap) using high vacuum of 1 mmHg at 45C.

[00139] The oily residue was dissolved in methanol and purified using a Silica gel 230- 400 mesh column chromatography. A gradient of methanol 5-25% in ethyl acetate was used as eluent.

[00140] Trehalsoe-indomethacin conjugate (Indose) and Trehalose-dichlorofenac conjugate (Diclose) have been obtained as pale-yellow solids, resulting in the 32% and 15% yield, respectively.

EXAMPLE 2

[00148] Previous studies have highlighted the keen involvement of heparanase in the pathogenesis of inflammatory diseases including AP. Specifically, the inventors evidenced that pancreatic heparanase expression and activity are significantly increased following cerulein-induced AP. Moreover, pancreas edema and inflammation, as well as the induction of cytokines and signaling molecules following cerulein administration were attenuated markedly by PG545 and SST0001, selective heparanase inhibitors, implying that heparanase plays a significant role in AP. [00149] Notably, all the above features appear even more pronounced in transgenic mice over expressing heparanase, suggesting that these mice can be utilized as a sensitive model system to reveal the molecular mechanism by which heparanase functions in AP.

[00150] Heparanase expression and activity in the induced Acute pancreatitis (AP). Serum levels of amylase and lipase typical of AP were increased substantially (4 fold) in cerulein-treated WT mice (Fig. 1) and even higher ~7 fold induction of lipase and amylase levels was noted in Hpa-Tg mice following cerulein treatment (Fig. 1). In addition, AP was associated with pancreatic edema as evident by increased pancreatic index (%Pancreatic weight/Body weight) (Fig.l). Notably, the elevation in biochemical parameters and pancreatic edema was markedly reduced by the heparanase inhibitors PG545 and Roneparstat in WT and Hpa-Tg mice (Fig. 1), altogether implying that heparanase plays a substantial role in AP.

[00151] Histological analyses. To examine further the involvement of heparanase in the pathogenesis of AP, pancreatic morphology was evaluated in WT and Hpa-Tg mice by histopathological and electron microscopy analyses. Cerulein treatment resulted in typical edema in WT mice and even more sever edema was noted in Hpa-Tg mice exposed to cerulein (Fig. 2). Notably, tissue edema was markedly restored in mice treated with PG545 and SST0001 (Fig. 2), further supporting the notion that heparanase plays a role in AP.

[00152] In the next step, the inventors examined the effects of Asprilose as pre and post treatment on AP and the results are presented in Figures 3&4. As can be seen, administration of Asprilose (mono or dimer) either as early or post treatment exerts pancreato-protective effects against AP. The beneficial effects of Aspirlose was evident at the histological levels too (Fig. 3). It is postulated that this new compound may be efficient as a novel therapeutic agent for the treatment of AP.

[00153] Moreover, the inventors examined the pancreato-protective effects of Indose and Diclose in AP. The newly synthesized compounds, “Indose” or “Diclose”, were well tolerated and effective against AP in WT and Hpa-Tg mice and reduced the severity of AP at 16 and 32 mg/kg doses (see Fig. 5 and Fig. 6, respectively).

[00154] Further, the inventors examined the acute toxicity of the compounds Indose and Diclose. A series of dosages: 8mg/kg, 32mg/kg,64mg/kg, 128mg/kg, 256mg/kg, 512mg/kg, 768mg/kg, 1024mg/kg, HOOmgmg/kg, and 1200mg/kg were injected by intraperitoneal injection in the presence of sterile water as carrier. Each dosage was injected to a group of 5 wild type mice. Indose exhibit a LD50 of 900mg/kg and Diclose a LD50 of 780 mg/kg. No mortality was observed, for both Indose and Diclose, at a dosage of 500 mg/kg, indicating both compounds have low toxicity.

[00155] To this end, the new pharmaceutical compositions of the invention have a negligible toxicity and showed a significant efficacy in-vivo. Thus it is postulated that the pharmaceutical compositions or the compounds of the invention may provide a novel therapeutic maneuver for the treatment of disease(s)/condition(s) disclosed herein.

[00156] While the present invention has been particularly described, persons skilled in the art will appreciate that many variations and modifications can be made. Therefore, the invention is not to be construed as restricted to the particularly described embodiments, and the scope and concept of the invention will be more readily understood by reference to the claims, which follow.
