Description

METHOD FOR THE PREPARATION OF MICRO-RNA AND ITS THERAPEUTIC APPLICATION FIELD OF THE INVENTION

The present invention relates to compositions comprising a therapeutically effective amount of miRNAs, their use for the treatment of medical conditions benefiting from being treated with these compositions. Also encompassed by the present invention are methods for the preparation of a composition comprising miRNAs.

BACKGROUND OF THE INVENTION

MicroRNAs (miRNAs) are short (about 21-24-nucleotides) noncoding RNAs that are thought to regulate gene expression through sequence-specific base pairing with target mRNAs. The underlying mechanism is still poorly understood, but it appears to involve the inhibition of translational initiation.

Many of the functional roles of microRNAs hint at the potential involvement of microRNAs in human disease, and as major regulators of growth and proliferation. As many microRNAs are de-regulated in primary human tumours, a role of microRNAs in human cancers has been suggested. Accordingly miRNA deficiencies or excesses have been correlated with a number of clinically important diseases ranging from myocardial infarction to cancers.

Potential roles of microRNAs in the development as well as the regulation of the immune system have also been suggested.

Inflammation, a key component of the immune system, functions in both defence

(physiological) and in pathophysiological events to maintain the homeostasis of tissues, organs and individual cells. Acute inflammation is a short-term process characterized by the classic signs of inflammation, i.e. swelling, redness, pain, heat, and loss of function, due to infiltration of tissues by plasma of several activated components such as interleukins, antibodies, hormones etc. and leukocytes. It occurs as long as the injurious stimulus is present and ceases once the stimulus has been removed. Chronic inflammation is a pathological condition characterized by concurrent active inflammation, tissue destruction, and attempts at repair. Chronically inflamed tissue is characterized by the infiltration of mononuclear immune cells (monocytes, macrophages, lymphocytes, dendritic cells and other plasma cells), tissue destruction, and attempts at healing, which include angiogenesis and fibrosis. Without inflammation, wounds and infections would not be able to heal and progressive destruction of the tissue would threaten the survival of the organism. Inappropriate inflammation, on the other hand, can lead to various diseases, including but not limited to indications such as hay fever, atherosclerosis, neurodegenerative diseases such as

Alzheimer's, cancer and rheumatoid arthritis. For these reasons, inflammation is tightly regulated by the body.

Mononuclear immune cells are under infectious conditions attracted to the site of infection in an attempt to eliminate the foreign pathogen through phagocytosis. Leukocytes and dendritic cells are here activated by the pathogens to synthesize and release proinflammatory cytokines such as IL- la, IL- 1β, IL- 3, IL-5, IL-6, IL-8, TNF-a (tumor necrosis factor-a), GM- CSF (granulocyte-macrophage colony-stimulating factor), NF-κΒ (nuclear factor kappa-light- chain-enhancer of activated B cells), and MCP- I (monocyte chemotactic protein- 1). These released cytokines then further attract more immune cells to the infected site, amplifying the response of the immune system to defend the host against the foreign pathogen. Dendritic cells are derived from hemopoietic bone marrow progenitor cells. These progenitor cells initially transform into immature dendritic cells. These cells are characterized by high endocytic activity and low T-cell activation potential. Immature dendritic cells constantly sample the surrounding environment for foreign pathogens. This is done through pattern recognition receptors such as the toll-like receptors (TLRs), which recognize specific chemical signatures found on subsets of pathogens. Once they have come into contact with a presentable antigen, they become activated into mature dendritic cells and begin to migrate to the lymph node. Immature dendritic cells phagocytize pathogens and degrade their proteins into small pieces and upon maturation present those fragments at their cell surface using MHC molecules. Simultaneously, they upregulate cell-surface receptors that act as co- receptors in T-cell activation. Once in the lymph nodes they act as antigen-presenting cells, in activating helper T-cells and killer T-cells as well as B-cells by presenting them with antigens derived from the pathogen, together with non-antigen specific co-stimulatory signals.

The biological role and in vivo functions of most mammalian miRNAs are still poorly understood and the underlying mechanisms of why and how miRNAs become deregulated are largely unknown.

Glucocorticoids (also referred to as "corticosteroids" or "steroidal drugs") as well as

Nonsteroidal Antiinflammatory Drugs (NSAIDs) represent today one of the most effective clinical treatment for a range of inflammatory conditions, including acute inflammation. However, these drugs can have side effects that may threaten the overall health of the patient.

There remains a need to develop a safe, effective method of treating autoimmune diseases, inflammatory disorders, and cancers or other indications associated with abnormal cell growth or cell division. The present invention provides compositions and methods for treating such diseases and disorders.

In some embodiments of the invention, peripheral blood is removed from an individual, such as with a syringe, an thereafter transferred to a vessel, wherein the blood is activated by incubation in the presence of beads to stimulate the production of miRNA. Alternatively, the peripheral blood may be removed directly into a vessel comprising beads to stimulate the production of miRNA. Serum may then be collected and used according to the invention.

In still another alternative peripheral blood is removed from an individual, the buffy coat and/or serum is harvested from the blood preparation and transferred to a vessel comprising beads to stimulate the production of miRNA.

In still other alternatives peripheral blood, a preparation of bone marrow, or other preparation containing blood components is removed from an individual or obtained in other ways, transferred to a device as described herein or potentially in any one of EP0740964, EP1638691, WO2008097230, EP1093390, or EP1549552, the device being prefilled in the chamber for collection of supernatant with beads to stimulate the production of miRNA, or the wall of the chamber for collection of supernatant having a surface structure, including a clean surface, which stimulates the production of miRNA according to methods of the present invention.

Beads which may be used for this purpose include, but are not limited to, glass or plastic beads between 0.5 and 10 mm or between 0.5 and 5 mm in diameter, optionally treated with an agent, such as CrS0₄, which stimulates lymphocyte proliferation (Mignini et al., 2004, Preventive Med 39(4) 767-775; Rhee et al., 2002, Clin Exp Immunol 127(3) :463-469).

Medical grade glass beads, 4 mm in diameter may be modified by incubation in 50% CrS0₄. The treated or untreated beads are placed in a suitable container, such as a microtiter plate, centrifuge tube, culture tube, or syringe or other device described herein, and then sterilized (e.g. by autoclaving or gamma irradiation). Peripheral blood may in some embodiments be introduced into the bead-containing container, and then incubated, aseptically, at 37 °C, optionally with 5% C0₂, for example for 2-200 hours, such as for 2-150 hours or 2-48 hours. Serum may then be collected from the bead/blood suspension by centrifugation, for example at 4200 rpm for 10 minutes. Typically, 30 percent of the total original peripheral blood volume may be recovered. The resulting serum containing miRNA may then be stored at -20 °C.

In a related, specific, non-limiting embodiment of the invention, enhancing agents may be added to the peripheral blood sample prior to, or as an alternative to, incubation with beads. For example, 5 μg enhancing agent per ml of peripheral blood may be added.

In some, non-limiting embodiment of the invention, a blood serum preparation is prepared by collecting serum from peripheral blood, optionally incubated with beads and/or an enhancing agent, by centrifugation to remove the formed blood elements (e.g., at 3000-5000 g for 10 minutes), followed by ultracentrifugation, for example, at 100,000 g, for 1 hours. The resulting pellet may be resuspended in physiologic saline, and then preferably sterilized (e.g., by filtration through a 0.2 μιη filter).

The blood may in some embodiments be treated with an anticoagulant, such as heparin or citrate. The invention provides in a further embodiment for the incubation of the body fluid or elements thereof in the container to be carried out over a period of from 2 to 200 hours, such as 2-150 hours, such as 2-100, or 2 to 72 hours, such as 20 hours, preferably at

physiological or room temperature, that is to say 20 °C to 41 °C, in particular at 35-37 °C. The invention also provides in one configuration of the invention for the body fluid to be treated further after formation of the therapeutically or prophylactically active protein or compound in the body fluid, in order, for example, to remove particular constituents of the latter, for example blood plasma or blood platelets. This removal may in some embodiments of the invention be carried out by centrifugation, filtration or coagulation to remove coagulation factors and/or clotted material. In alternative embodiments of the invention the body fluid composition may be mixed with other body fluids or body fluid components. Accordingly, in some particular embodiments, an activated body fluid composition, such an activated blood serum preparation is mixed with Platelet-rich plasma prior to administration to the patient. This is particularly suitable for use in the treatment of indications associated with joints, tendons, ligaments, and muscles, such as in the treatment of muscle pain, polymyalgia rheumatica and whiplash-associated disorders.

As discussed above the present invention relates to methods for the treatment or for alleviating the symptoms of a medical condition, compositions comprising a blood serum preparation for the preparation of a medicament for the treatment or for alleviating these symptoms, and the use of these compositions in the preparation of medicaments. In some aspects of the invention, a blood preparation is activated in container or by alternative methods. In some alternative embodiments a blood preparation is replaced with another body fluid as described elsewhere. Accordingly, in some alternative embodiments, a container is filled with a body fluid or elements thereof, such as in vitro cell cultures, bone marrow exudates and the like, and treated by methods similar or identical to methods used for treating blood preparations. In some embodiments the body fluid is taken with a syringe directly from the patient.

In some embodiments, the buffy coat is removed from a blood preparation and activated. This may be in the presence or absence of the plasma fraction of the blood preparation. In some embodiments the buffy coat with or without plasma is incubated in the presence of a growth medium, such as during the activation on a surface or prior to said activation.

In some embodiments the compositions according to the invention further comprise micelles, vesicles or liposomes, and preferably the micelles, vesicles, liposomes comprise the miRNA.

Liposomes are typically completely closed structures comprising lipid bilayer membranes containing an encapsulated aqueous volume. Liposomes may contain many concentric lipid bilayers separated by an aqueous phase (multilamellar vesicles or MLVs), or alternatively, they may comprise a single membrane bilayer (unilamellar vesicles). The lipid bilayer is composed of two lipid monolayers having a hydrophobic "tail" region and a hydrophilic "head" region. In the membrane bilayer, the hydrophobic (nonpolar) "tails" of the lipid monolayers orient toward the centre of the bilayer, whereas the hydrophilic (polar) "heads" orient toward the aqueous phase. The lipid components that may be used in the liposomes described herein are generally described in the literature. Generally, these are phospholipids - such as phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, phosphatidic acid, phosphatidylinositol and/or sphingolipids. Additional components, fore example, sterols - such as cholesterol - or other components - such as fatty acids (e.g., stearic acid, palmitic acid), dicetyl phosphate or cholesterol hemisuccinate, may be used. Moreover, the liposome membrane can also contain preservatives. The liposome membrane may also contain components, which modify their dispersion behaviour. They include, for example, PEGylated derivatives of phosphatidylethanolamine, lipids - such as GM 1 - or conjugates of sugars and hydrophobic components - such as palmitic or stearic acid esters of dextran.

The basic structure of liposomes may be made by a variety of techniques known in the art.

For example, liposomes have typically been prepared using the process of Bangham et al., (1965 J. Mol. Biol., 13: 238-252), whereby lipids suspended in organic solvent are evaporated under reduced pressure to a dry film in a reaction vessel. An appropriate amount of aqueous phase is then added to the vessel and the mixture agitated. The mixture is then allowed to stand, essentially undisturbed for a time sufficient for the multilamellar vesicles to form.

Liposomes may be reproducibly prepared using a number of currently available techniques. The types of liposomes which may be produced using a number of these techniques include small unilamellar vesicles (SUVs) [See Papahadjapoulous and Miller, Biochem. Biophys. Acta., 135, p. 624-638 (1967)], reverse-phase evaporation vesicles (REV) [See U.S. Pat. No.

4,235,871 issued Nov. 25, 1980], stable plurilamellar vesicles (SPLV) [See U.S. Pat. No. 4,522,803, issued June 11, 1985], and large unilamellar vesicles produced by an extrusion technique as described in copending U.S. patent application Ser. No. 622,690, filed June 20, 1984, Cullis et.al., entitled "Extrusion Technique for Producing Unilamellar Vesicles". In a preferred embodiment, the liposomes are prepared using the following method. The lipids are prepared by pipetting the appropriate amount of stock solutions of, for example, CDAN, DOPE and aminoxylipid (CPA), respectively, into a round bottomed flask pre-treated with nitric acid and dimethylsilyldichlorid, evaporating the solvent, and hydrating the dry lipid film with water under heavy vortexing, to generate multilamellar liposomes.

Unilamellar liposomes may be produced by sonicating the multilamellar liposomes for 30 mins. Preferably, this is continued until a size of smaller than about 30nm is reached.

EXAMPLES EXAMPLE 1

Preparation of activated serum

Blood is collected from either an animal or human being or alternatively a population of animals or human beings, preferably without any infection or fewer. The blood is taken by a venous transcutane puncture and collected in a container. Hereafter whole blood or alternatively buffy coat with or without plasma is transferred to a container with a surface, or containing an activating substances such as glass beats etc, preferably a 60 ml container suitable for centrifugation comprising two rubber ports for injection and a small hole for pressure equalization, the container being with or without 2 -25 gram of glass beads, 1-8 mm, such as 4mm. In some embodiments a buffy coat preparation with or without a plasma fraction is incubated together with a growth medium. This may be either prior to or during the procedure exposing the body fluid to the activating surfaces. The sample is regurgitating or in any other procedure exposing the blood cells to the activating surfaces for 1, 2, 4, 10, 24, 48, 72, 96, 120, or 150 hours in 37 degrees celcius.

Hereafter the incubation is terminated by lowering the temperature to room temperature and separating the serum from the clotted blood by filtration or centrifugation. In some embodiments of the invention the whole blood is incubated using anticoagulants and after the incubation time the serum is collected by centrifugation or filtration.

The prepared serum, plasma or buffy coat preparation is then stored either at room temperature, frozen at -5-18 degrees celcius or otherwise prepared for freezing storage to optimized the preservation of more complex structures as membrane like vesicles etc. EXAMPLE 2

Alternative procedure for the preparation of activated serum

Blood is incubated in sterile 60 ml containers over a time period of 2-72, 96, 120, or 150 hrs, which container contain glass beads (SiliBeads-Borosilicate, Sigmund Linder, Germany). Glass beads are 2-5 mm, such as 2-4 mm in diameter, and are of medical grade. The container are packed with 5-25, such as 18 grams of beads and may be sterilized either by autoclaving or gamma- irradiation. Blood culture techniques: In all experiments, containers (e.g. 60 ml container) packed with beads are filled with freshly drawn human whole blood from healthy, male or female donors, between 20 and 70 years old, without anti-coagulants unless mentioned otherwise. Whole blood cultures are established under sterile, laminar flow conditions. Incubation is carried out aseptically at 37°C, 5% C0₂ for 2-72 hrs intervals. After incubation, serum is retrieved and centrifuged (4200 rpm, 10 min). Alternatively after incubation the serum is separated from the blood cells by centrifugation at 5000 g for 10 min.

EXAMPLE 3 Treatment of human subjects with activated blood serum

Patients are given epidural perineural or intramuscular injections three times once a week. Objective and subjective assessments are made at six times (tl-t6) per patient including visual analog scale (VAS) (Joyce et al., Eur J Clin Pharmacol. 14:415-20 (1975)), Oswestry Pain Questionnaire (Fairbank et al. Spine, 25: 2940- 2953(2000)), SF-36 (short form health survey) (Ware et al., Med. Care, 30:473-483 (1992)), and standardized clinical examination.

2 ml of activated serum is injected. One group is given activated serum, another is given 10 mg Triamcinolone, and the last is given 5mg Triamcinolone. Triamcinolone is a steroid commonly used to treat inflammation, allergies, arthritis, and asthma. It has been shown that Triamcinolone is effective at reducing lumbar radicular pain, (randomized double blind study, Kramer Eur Spine 1997). Similar effects were seen with activated blood preparation as prepared by a method according to any one of examples 1 or 2.

EXAMPLE 4

5 severe endometriosis patients also having adenomyosis were treated in 6 weeks with conditioned serum prepared as described in example 1 or 2. 5 ml of activated serum were administrated to the patient each intramuscular every week for 5-6 weeks. Their symptoms were significantly relieved. The background for treating intramuscularly was based on several experimental

intramuscular injections in 4 horses during the period of a 2 year. This animal study proved that muscular tenderness was cured by the same intervals of injections.

EXAMPLE 5 2 abortus habitualis patients were treated during In Vitro Fertilisation (IVF) with the same regime as described under example 4, and one conceived during this study.

EXAMPLE 6

3 colitis ulcerosa and 1 Crohn patients has been through the same timed preparation and injection of activated serum with significant improvement of their conditions/disease, thus in the acute initial treatment a shorter interval for administration is beneficial and after a plateau phase in the symptoms has been reached, a longer interval between administration of the serum seems to stabilize all symptoms. The benefit of this method of sequential strategy for administration of the substances is to enable the invention to cope with the high activity of the disease in the acute phase and changing the activity of the substances when the disease is in a stable phase.

Further to this, the administration of the activated serum has an impact of the course of the disease by administration of a larger volume of conditioned serum in the start of the treatment regimens, such as 5 ml, 10ml or 20 ml. One patient diagnosed with severe colitis uicerose having defecation 20 times daily, strictures in the bowel, visualized by coloscopy prior to the treatment with activated serum. The patient was completely cured within 7 weeks (certified by an external doctor performing the coloscopy). EXAMPLE 7

In vitro culture of stem cell producing mirRNA including cell cultures of placental origin:

Hematopoietic stem cells or cell cultures of placental origin are cultured under in vitro conditions for a period of time optionally in a container containing the activating substances such as glass beats etc Alternatively the cell and cell culture medium may in a subsequent step be transferred to a container containing the activating substance such as glass beats etc.

After regurgitating or in any other procedure exposing the cells to the activating surfaces for 1, 2, 4, 10, 24, or 48 hours in 37 degrees Celsius the sample may be left untouched for a total of 5 hour, to 24 hours depending on the volume, the surface area of the vessel and number of cells in a given sample.

Hereafter the incubation is terminated by lowering the temperature to room temperature.

The prepared cell preparation may then stored either at room temperature, frozen at -5-18 degrees Celsius or otherwise prepared for freezing storage to optimized the preservation of more complex structures as membrane like vesicles etc. EXAMPLE 8

Activated serum as prepared by examples 1 or 2 was tested in an assay to determine the specific miRNAs upregulated in response to the activation. A miRCURY™ LNA Array microRNA Profiling Service was performed by Exiqon (Denmark). Results are summarized in table 1.

EXAMPLE 9

Reduction of tumour cell proliferation in vitro Study of impact on growth of human and equine malignant melanoma cells after exposure to activated serum.

Cells of a primary tumour from human and equine malignant melanoma tissue was grafted and put in to passage by in vitro growth. Serum from human and horse was activated for 24 hours or 48 hours as described in example 1 or 2. 2%, 5%, or 10% of the activated serum was applied to the growth medium of the primary tumour cells

Cell proliferation of the primary tumour cells as measured by cell counts was significantly reduced in vitro after exposure to the activated serum. Example 10

In vivo tumour mass reduction

Serum was prepared as described in example 1 or 2 with 48 hours of activation.

In an equine study on 4 malignant melanoma tumors of less than 1 cm in diameter in the skin, the horse was injected in the melanoma with 2 or 5 ml of activated serum (48 h) prepared from another horse, 3 times with an interval of 3 days. All melanomas disappeared completely.

In the same horse one large melanoma (hwd: 5cm X 1cm X 1cm) was injected into the melanoma with 2 ml of serum prepared from another horse. Injections were repeated 4 times. The melanoma decreased significantly in size to hwd: 2cm X 0.4cm X 1cm. In a further study a gray gelding age 10 yrs was intramuscularly injected with serum preparation (incubation 48 h) a total of 5 ml every week for 6 weeks. During this period malignant melanoma plaque around anus was totally abolished and not longer seen. A period of 2 month observation time was followed without relapse.

Example 11 4 horses with cutaneous affection of sarcoid tumors are injected with 5 ml of serum ( 48 h incubation) ever 5th day for a periode of 10 weeks. The tumor will disappear. Example 12

Primary tumour cells prepared as described in example 9 was added in a concentration of 10.000 to 100.000 cells per ml to serum in conjunction with the activation of the serum. A significant enrichment (up to 50 % higher) in miRNA of the prepared serum was seen as compared to a serum control without tumour cells.

Example 13

An increased content of miRNA in human serum preparation was seen, when the time period of incubation was up to 150 h of incubation.

Human serum was activated as described in example 1 or 2 however with a period of 150 hours of incubation of the human serum. The samples were analysed for amounts compared to a control sample by quantitative PCR.

Example 14 Capture of miRNA by magnetic beads

Serum prepared according to example 1 or 2 with 96 hours of activation period and with a pre-known enriched amount of miRNA was mixed at ratio 1 : 1 with polyethyleneimine (PEI) coated iron magnetic nanoparticles (Chemicell Gmbh, Berlin, Germany) essentially as described in Huttinger et al J. Gene Med 2008; 10: 655-667. The preparation was gently mixed for 20 minutes. The magnetic nanoparticles were drawn to the side of the container using a neodymium-iron-boron magnet (Neo Delta magnet NE2010; IBS magnet, Berlin, Germany). The liquid supernatant free of nanoparticles was recovered and analysed for miRNA be quantitative PCT. The amounts of miRNA in the supernatant were reduced between 50-80 % compared to pre-mixing levels. The positively charged magnetic nanoparticles mediated binding of miRNA via electrostatic interactions. Serum with enriched amounts of miRNA mixed with magnetic nanoparticles or magnetic nanoparticles following mixing with miRNA enriched serum after removal of the supernatant, may be used to position in or close to the tumor in vivo after injection in the peripheral place using magnets over the tumour.
