Description

FIELD OF THE INVENTION

The present invention relates to pharmaceutical compositions for a combination therapy with a cytokine antagonist and a corticosteroid. By means of the combination therapy diseases such as osteoarthritis (including inflammatory types of osteoarthritis), tendon conditions and/or degenerative spinal diseases can be treated, wherein the treatment is preferably carried out locally.

TECHNICAL BACKGROUND

Osteoarthritis refers to “joint wear” to a higher degree than typical for a certain age. It is accompanied by a loss of cartilage in the respective joint, which results in pain and function deterioration. Excess strain, congenital or traumatic causes such as joint malpositions or also bone deformation through bone diseases like osteoporosis are viewed as causes. It can also result from another disease such as joint inflammation or accompany effusion caused by excess strain.

Generally all joints can be affected by osteoarthritic changes. In Germany the disease is most frequently located in the knee joint. Osteoarthritis is one of the most common reasons for seeking advice at a general practitioner's practice. Approximately 10% of the population in Western countries suffer from osteoarthritis. If osteoarthritis diseases of the small vertebral joints and the degenerative intervertebral disc diseases are added, even approx. 15%-20% of the population are affected. The risk of suffering from osteoarthritis increases with age. About two thirds of people over 65 years are affected by the disease, however, not all persons affected also suffer from the symptoms.

For the treatment of osteoarthritis some therapy forms are already known. This includes conservative (e.g. medicinal) therapies as well as surgical procedures to the point of replacing the complete joint by a prosthesis. In order to avoid these extensive and irreversible interventions, an effective medicinal treatment is generally preferred to delay the point in time of a complete joint replacement as far as possible.

However, many medicinal treatments also have disadvantages. On the one hand this is due to the side effects of the medicaments themselves, but their effects are also partially limited.

A medicinal agent frequently used for treating osteoarthritis is cortisone and related corticosteroids. These are administered systemically, however mostly locally as an injection into the affected joint. However, it is found that the positive effect of the corticosteroid already decreases after just one week. This is clinically proven by randomized studies and clinical experience.

A further medicament which can be used for treating osteoarthritis is the protein IL-1Ra, which is produced naturally in the body, or an isoform or fragment thereof, which shows a similar activity. Interleukin-1-receptor antagonist (IL-1 Ra) binds to the same receptors on the cell surface as interleukin-1 (IL-1), but does not trigger the signalling cascade normally caused by IL-1Ra binding. By binding to the IL-1 receptor, IL-1 Ra blocks the binding of IL-1 and thus prevents its transduction of signals and thus the inflammatory effect of IL-1 on the target cells.

Treatment of patients with autologous serum in which IL-1 Ra was enriched and is contained therein among other factors, is known in the state of the art. IL-1Ra used in this way is also called Orthokine. A recombinant IL-1Ra fragment, Anakinra, in contrast surprisingly did not show any effects in the treatment of osteoarthritis compared to a placebo treatment. Anakinra is an isoform of the human interleukin-1 receptor antagonist shortened to amino acids 26-177 and terminally L-methionylated and has a sequence length of 153 amino acids. The preparation is done for example by means of Escherichia coli strains using recombinant methods.

In the light of the state of the art, the problem to be solved was thus to provide a medicinal treatment of osteoarthritis, which is more effective and particularly shows a good long-term efficacy.

SUMMARY OF THE INVENTION

Surprisingly it was now found that the efficacy, in particular the long-term efficacy of corticosteroids such as cortisone when treating osteoarthritis, inflammatory types of osteoarthritis and degenerative spinal diseases, can be significantly or synergistically improved by additional administration of a cytokine antagonist like Orthokine and Anakinra. This is particularly found when locally administering the therapeutics into the joint to be treated. In particular this is extremely surprising in the light of the fact that this advantageous effect occurs when additionally administering natural IL-1Ra such as Orthokine as well as recombinant IL-1Ra such as Anakinra, even though it is proven that Anakinra alone does not show any effect in the treatment of osteoarthritis and degenerative spinal diseases. The present invention creates the possibility of rendering the recombinant IL-1 Ra suitable for a treatment of osteoarthritis and spinal diseases, as it is not suitable for the treatment of these diseases on its own. A similar, surprisingly good efficiency and high safety of the combination of these agents was also found for autoimmune diseases such as neurodermitis and alopecia areata, wherein mostly the anti-inflammatory effect plays a role.

A possible explanation for this fact is that the cytokine antagonists have an anabolic effect and can neutralize or even reverse the harmful catabolic effect of the corticosteroids in the affected joints. Thus, in the treatment of for example osteoarthritis, the corticosteroids can, apart from the cytokine antagonists, be alternatively or additionally combined with anabolic growth factors in order to achieve a similar or even potentiating effect. Thus the invention enables the preparation of a corticosteroid which does not have the known harmful effects in osteoarthritis, which can consist of increased cartilage destruction, by combining it with a cytokine antagonist.

Thus the present invention provides in a first aspect a pharmaceutical composition comprising a corticosteroid together with a cytokine antagonist and optionally a growth factor, wherein the cytokine antagonist is the naturally occurring or recombinant interleukin antagonist IL-1Ra protein, in particular Orthokine or Anakinra, and wherein the pharmaceutical composition is suitable for local administration.

The therapeutics may also be administered in two different pharmaceutical compositions simultaneously or sequentially. Accordingly, the invention in a second and third aspect provides a pharmaceutical composition comprising a cytokine antagonist and optionally a growth factor for use in a combination therapy together with a corticosteroid as well as a pharmaceutical composition comprising a corticosteroid for use in a combination therapy together with a cytokine antagonist and optionally a growth factor. In the second as well as the third aspect of the invention, the cytokine antagonist is the naturally occurring or recombinant interleukin antagonist IL-1Ra protein, in particular Orthokine or Anakinra, and the pharmaceutical composition is suitable for local administration.

In a fourth aspect according to the invention a kit is provided comprising a pharmaceutical composition comprising a cytokine antagonist and optionally a growth factor and a pharmaceutical composition comprising a corticosteroid. The cytokine antagonist is the naturally occurring or recombinant interleukin antagonist IL-1 Ra protein, in particular Orthokine or Anakinra, and the pharmaceutical compositions are suitable for local administration.

Furthermore, the invention in a fifth aspect relates to the use of a cytokine antagonist and optionally a growth factor for preparing a pharmaceutical composition for use in a combination therapy together with a corticosteroid and in a sixth aspect the use of a corticosteroid for preparing a pharmaceutical composition for use in a combination therapy together with a cytokine antagonist and optionally a growth factor. In the fifth as well as the sixth aspect of the invention the cytokine antagonist is the naturally occurring or recombinant interleukin antagonist IL-1 Ra protein, in particular Orthokine or Anakinra, and the pharmaceutical composition is suitable for local administration.

Further embodiments of the invention are shown in the following detailed description and in the claims.

DESCRIPTION OF THE INVENTION

The invention is based on the surprising finding that the treatment of joint and spinal diseases such as osteoarthritis, arthritis, inflammatory types of osteoarthritis and degenerative spinal disease as well as autoimmune diseases by means of corticosteroids can be significantly improved by additional administration of a cytokine antagonist and optionally of a growth factor. In particular, in the case of treatment with the recombinant IL-1Ra, Anakinra, only by combination with a corticosteroid, an effect is achieved which is much higher than the sole effect of the corticosteroid or which makes Anakinra in combination with a corticosteroid an effective agent at all in the treatment of the mentioned diseases. In the case of the natural IL-1Ra Orthokine a significant improvement of efficacy is observable especially regarding inflammatory or inflammatory progressing osteoarthritis or inflammation of the vertebral joints or the nerve root. Thus the invention is directed towards the combination therapy of such diseases by means of a corticosteroid together with a cytokine antagonist like Anakinra or Orthokine and optionally of a growth factor.

These different agents may be administered simultaneously—in the same formulation or in different formulations—or sequentially. The pharmaceutical compositions according to the invention, that comprise only one of the two different agents, as well as the kit according to the invention, may be intended for simultaneous administration on the one hand and for sequential administration of the cytokine antagonist and the corticosteroid on the other hand. Simultaneous administration however is preferred, particularly in only one formulation. This way the two pharmaceutical compositions of the kit according to the invention, for example, may be mixed in an appropriate ratio before being administered to the patient and may then be administered as a formulation. When sequentially administering the cytokine antagonist and the corticosteroid, the different agents are preferably administered within a time period of one week, preferably within 5 days, 3 days, one day or within 12 hours.

According to the invention, the cytokine antagonist may be combined with a growth factor. Optionally, a further cytokine antagonist is contained in the pharmaceutical composition according to the invention or the kit according to the invention.

The cytokine antagonist used according to the invention may be any substance or any mixture of substances that reduces or inhibits at least one, preferably substantially all of the biological activities of one or more cytokines in the body of the patient. The antagonistic effect may occur directly by the antagonist or indirectly, e.g. by activating or inhibiting further signalling pathways that also have an effect on the biologic activity of the cytokine. Preferably the biological activity of the cytokine is inhibited by blocking its interaction with one or more receptors to which it can bind. This can be achieved for example by competitive binding of the antagonist to the corresponding receptor(s) or by binding of the antagonist to the cytokine itself. Preferably the cytokine antagonist inhibits the effect of the cytokine IL-1.

The cytokine may be e.g. a protein, a peptide, a nucleic acid, a lipid or an organic compound. The cytokine antagonist may also consist of a mixture of two or more cytokine antagonists as described herein. In particular the cytokine antagonist may be a naturally occurring peptide or protein or also a recombinantly prepared peptide or protein. Furthermore the cytokine antagonist may be or comprise an antibody or antigen-binding fragment of an antibody, particularly an antibody or antibody fragment which can bind the respective cytokine or a cytokine receptor. Examples for suitable cytokine antagonists are interleukin antagonists, particularly IL-1 antagonists like IL-1 Ra, tumor necrosis factor (TNF) antagonists, particularly a TNF-α antagonist such as an anti-TNF-α antibody, interferon antagonists and chemokine antagonists. Particularly preferred is naturally occurring or recombinant IL-1Ra protein, preferably human IL-1Ra. IL-1 Ra preferably comprises or preferably consists of the amino acid sequence of an isoform or a homologue of the human IL-1 Ra according to SEQ ID NOs: 1, 2, 3, 4 or 5, an isoform of the equine IL-1Ra according to SEQ ID NOs: 6 or 7 or an isoform of the canine IL-1Ra according to SEQ ID NO:8. Preferably the pharmaceutical composition according to the invention or the kit according to the invention comprises such a cytokine antagonist in addition to the naturally occurring or recombinant IL-1Ra protein.

Furthermore, according to the invention, fragments or derivatives of IL-1Ra may be used as cytokine antagonist as long as they can exercise the desired function, i.e. the reduction or inhibition of one or more biological functions of IL-1. Fragments of IL-1 Ra preferably comprise at least 20, more preferably at least 40, 60, 80 or at least 100 amino acids of a natural IL-1Ra sequence. Preferably the fragments are naturally occurring secreted fragments of IL-1 Ra. In one embodiment, the IL-1Ra comprises amino acids 26 to 177 of the human IL-1Ra, preferably amino acids 26 to 177 of the sequence according to SEQ ID NO: 1. Derivates of IL-1 Ra are preferably homologous to natural IL-1 Ra and preferably have a homology or identity to natural IL-1 Ra of at least 60%, more preferably at least 70%, 75%, 80%, 85%, 90%, 95% and most preferably at least 98% over an area of at least 20 contiguous amino acids, preferably at least 40, 60, 80 or at least 100 contiguous amino acids and most preferably over the total length of IL-1 Ra. Particularly preferred is the IL-1 Ra isolated from natural biological samples like blood, also called Orthokine, as well as the IL-1Ra fragment having amino acids 26 to 177 of human IL-1Ra, also called Anakinra. The preparation of Orthokine is described inter alia in Patent Application Nos. WO 00/46249 A1 and WO 03/080122 A1. Anakinra as well as further IL-1 antagonists that may be used in this invention are described inter alia in Patent Application EP 0 343 684 A1.

In the preparation of IL-1Ra from natural biological samples such as blood, like e.g. Orthokine, the obtained IL-1Ra solution preferably also contains growth factors, which may be responsible for the surprising efficacy of the combination of agents according to the invention. Thus, according to the invention, the cytokine antagonist may also be present in combination with one or more growth factors or be replaced by one or more growth factors according to the invention. The growth factor preferably has an anabolic effect. Examples for suitable growth factors are TGF-β, IGF, BMP, HGF and VEGF. Also comprised are analogues, derivatives and fragments of these growth factors as long as they have the desired effect, i.e. particularly their effect as growth factor.

The corticosteroid used according to the invention may be any naturally occurring as well as synthetically prepared corticosteroid. It may particularly be a glucocorticoid, a mineralcorticoid or an androgen, wherein glucocorticoids are preferably used. A mixture from two or more corticosteroids as described herein may also be used. Examples for glucocorticoids are cortisone, hydrocortisone, prednisone, prednisolone, cloprednol, deflazacort, fluocortin, triamcinolone, dexamethasone, methylprednisolone, fluprednisolone, clocortolone, clobetasone, alclomethasone, flumethasone, fluoprednidene, fluorandrenolone, betamethasone, beclomethasone, fluocortolone, mometasone, fluticasone, halomethasone, fluocinolone, diflorasone, desoximethasone, fluocinonide, amcinonide, halcinonide, diflucortolone, clobetasol and paramethasone. Examples for mineralcorticoids are aldosterone, deoxycorticosterone and fludrocortisone, and examples for androgens are dehydroepiandrosterone (DHEA) and estrogens. The corticosteroid may be used as a free compound or in the form of a salt, ester or prodrug. In preferred embodiments the corticosteroid used is triamcinolone, cortisone, hydrocortisone, prednisolone or prednisone.

In preferred embodiments the pharmaceutical compositions according to the invention and/or the kit according to the invention are intended for use in the treatment of joint diseases such as osteoarthritis, arthritis, joint inflammation and inflammatory loss of cartilage, tendon conditions, degenerative spinal diseases and also autoimmune diseases. The osteoarthritis to be treated may be caused by excess strain, have congenital or traumatic causes or be the result of another disease such as an inflammation. The osteoarthritis to be treated is preferably an activated osteoarthritis or an inflammatory osteoarthritis. The pharmaceutical compositions according to the invention may be used in the treatment of osteoarthritis and arthritis in any joint like for example knee joint, hip joint, ankle joint, shoulder joint, vertebral joints, finger joints, cubital joint, toe joints, temporomandibular joint and wrist joint. The arthritis to be treated may be an arthritis caused by an infection such as bacterial arthritis or an arthritis not caused by an infection such as rheumatoid arthritis, psoriatic arthritis or gouty arthritis. Alternatively the pharmaceutical composition according to the invention and/or the kit according to the invention may also be intended for the use in the treatment of a disease different from one or more of the mentioned diseases (e.g. rheumatoid arthritis). The degenerative spinal disease to be treated may be a herniated disc for example. Autoimmune diseases comprise inter alia autoimmune diseases of the joints like for example Morbus Bechterew, rheumatoid arthritis and systemic lupus erythematodes as well as other autoimmune diseases like particularly neurodermitis and alopecia areata.

The pharmaceutical compositions according to the invention and/or the kit according to the invention are preferably intended for local administration. Thus in preferred embodiments they are intended for injection, particularly injection into the body region to be treated, particularly into the affected joint, into the affected nerve root or into the affected disc or into the local environment thereof. The pharmaceutical composition is thus particularly intended for intraarticular and/or periradicular injection. Alternatively the pharmaceutical compositions according to the invention may be formulated for topical administration, particularly as a cream or gel or for systemic administration, particularly oral administration in the form of tablets, capsules or pastilles. The type of administration depends inter alia on the disease to be treated. In local osteoarthritis or degenerative spinal disease, local administration of the pharmaceutical compositions according to the invention is preferred. In preferred embodiments the pharmaceutical compositions according to the invention and/or the kit according to the invention are exclusively intended or suitable for an administration different from systemic administration.

The pharmaceutical compositions according to the invention are suitably formulated for the different types of administration in a manner known to the person skilled in the art. Thus a pharmaceutical composition suitable for injection preferably has the form of a solution or dispersion or also a dry form e.g. as a powder or lyophilisate, which must be dissolved in an appropriate solvent such as water before the injection. The pharmaceutical compositions according to the invention contain the cytokine antagonist and/or the corticosteroid in therapeutically effective amounts. The cytokine antagonist is thus present preferably in a concentration of 0.5 to 150 mg/dose in the pharmaceutical compositions containing the cytokine antagonist, but may also be present in a much lower concentration such as 1 ng/dose or more, for example between 1 and 1000 ng/dose. These lower dose concentrations may be used particularly in a combination with growth factors and/or in natural IL-1Ra preparations like for example compositions with Orthokine. The higher dose concentrations are preferred for example for recombinantly prepared cytokine antagonists like Anakinra. The corticosteroid preferably has a concentration of 1 to 80 mg/dose, more preferably 5 to 40 mg/dose in the pharmaceutical compositions containing the corticosteroid. Furthermore, the pharmaceutical compositions according to the invention may additionally contain one or more carriers and/or one or more excipients.

The pharmaceutical compositions of the invention may also be intended for a treatment of patients who had already undergone another treatment of the relevant disease, i.e. for example osteoarthritis, arthritis and/or degenerative spinal disease, particularly if this other treatment was not successful or the disease's symptoms at least partially returned after an initially successful treatment. In preferred embodiments this other treatment is a therapy with a cytokine antagonist like for example Anakinra or Orthokine but without a corticosteroid, or a therapy with a corticosteroid, especially a glucocorticoid as described above, but without a cytokine antagonist.

Patients in the sense of the invention may be humans or animals suffering from one of the diseases described herein. Thus the pharmaceutical compositions according to the invention may be suitable for treatment of a human and/or an animal like for example a dog, a cat, a horse, a cow, a pig, a goat or a camel or similar.

In a further embodiment of the invention the pharmaceutical compositions according to the invention are intended for use in a combination therapy together with exosomes. Exosomes are small vesicles coated by a lipid membrane, which are found in the extracellular space for example of the human body. They are formed and secreted by cells by separation from the cellular plasma membrane. Normally these exosomes also contain proteins which they have adopted from their original cell.

The exosomes may be directly contained in the pharmaceutical composition according to the invention or are administered simultaneously or sequentially in a separate composition. The exosomes are preferably prepared from a blood sample, wherein the exosomes are preferably autologous or allogeneic in relation to the patient to be treated. Methods for the preparation and administration of exosomes are described for example in patent application WO 2006/007529 A2.

Consequently a preferred embodiment provides that the pharmaceutical compositions of the invention are intended for a treatment in which exosomes are first obtained from a patient's blood sample and then subsequently re-administered to this patient together with a cytokine antagonist and a corticosteroid.

In case the combination therapy involves exosomes obtained from a blood sample of a patient, it is preferred in some cases to carry out a centrifugation step with at least 100 000 g in order to concentrate the exosomes, as such high relative centrifugal forces are especially suitable for concentrating exosomes. This applies to the first, second, third, fourth, fifth and/or sixth aspect of the present invention (pharmaceutical composition comprising a corticosteroid together with a cytokine antagonist, pharmaceutical composition comprising a cytokine antagonist for use in a combination therapy together with a corticosteroid, pharmaceutical composition comprising a corticosteroid for use in a combination therapy together with a cytokine antagonist, kit and/or use of a cytokine antagonist/a corticosteroid). Preferably such a centrifugation step is carried out in the treatment of diseases where a high concentration of exosomes is reasonable, preferably in the treatment of rheumatoid arthritis. It is particularly preferred if such a centrifugation step is carried out generally in case the combination therapy involves exosomes obtained from a blood sample of a patient. The centrifugation step with at least 100 000 g is preferably carried out for at least 30 min, particularly at least 60 min, as increasing the concentration is especially effective.
