Definitions
- the present invention is in the field of medicine. More specifically, this invention relates to compositions and methods for potentiating therapeutic effects of interferons.
- Interferons are naturally occurring proteins with antiviral, antiproliferative and immunoregulatory activity.
- the following definition for interferon has been accepted by international committee assembled to devise a system for the orderly nomenclature of interferons: "To qualify as an interferon a factor must be a protein which exerts virus nonspecific, antiviral activity at least in homologous cells through cellular metabolic processes involving synthesis of both RNA and protein.” J. Interferon Research, 1 : pp. vi (1980).
- the IFN-alpha family represents the predominant class of human IFNs. At least 23 different variants of IFN-alpha are known to date. All known subtypes of IFN-alpha show the same antiviral, antiparasitic, antiproliferative activities although they may differ in relative activities. IFN-alpha is mainly employed as a standard therapy against viral infections such as chronic viral hepatitis caused by hepatitis B and hepatitis C viruses. It is also active against a number of tumors such as hairy cell leukemia, metastasizing renal carcinoma and AIDS- associated angiogenic tumors known as Kaposi sarcomas.
- IFN-beta is used for treating multiple sclerosis. IFN-beta in combination with IFN-alpha has been used in the treatment of chronic active hepatitis B. The antiviral activity of IFN-beta is demonstrated also in the treatment of severe childhood viral encephalitis.
- IFN-gamma has antiviral and antiparasitic activities and also inhibits the proliferation of a number of normal and transformed cells, but the main biological activity of IFN-gamma appears to be immunomodulatory in contrast to the other interferons, which are mainly antiviral. IFN-gamma has been shown to be effective in the treatment of chronic polyarthritis.
- one unit of interferon is defined as the amount of interferon that reduced virus-induced cytopathic effect by 50 percent, and is calibrated against the international reference standard in International Units.
- interferon resistance is frequently associated with inflammation and specific cytokine action, especially IL-8.
- Khabar et al.. J.Exp.Med.. 186: 1077-85 (1997): Polyak et al.. J. Virology. 75: 6095-6106 (2001): Polvak et al.. J.Virologv. 75: 6209-6211 (2001).
- Succinic acid is a mammalian (human) metabolite, which plays a role in respiration and energy metabolism. Under a physiological pH, succinic acid exists in form of anion widely known as succinate.
- the present invention provides a method for potentiating a therapeutic effect of interferon in a mammal in need thereof, which comprises administering to said mammal an amount of interferon and an effective amount of succinic acid or a pharmaceutically acceptable salt thereof.
- interferon and succinic acid or a pharmaceutically acceptable salt thereof can be sequential in time or simultaneous with the simultaneous method being preferred.
- interferon can be administered before or after administration of succinic acid or a pharmaceutically acceptable salt thereof.
- the present invention provides a composition for potentiating a therapeutic effect of interferon in a mammal in need thereof, which comprises amounts of interferon and succinic acid or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable diluent or carrier.
- a composition for potentiating a therapeutic effect of interferon means that the effect achieved in a mammal with an amount of interferon when administered with an effective amount of succinic acid or a pharmaceutically acceptable salt thereof is greater than the effect achievable with the same amount of interferon without succinic acid or a pharmaceutically acceptable salt thereof and under otherwise equal conditions.
- this invention provides particularly advantageous methods of achieving the therapeutic effect with less than therapeutic levels of a interferon. Therefore, in practicing this invention, it is possible to minimize potential adverse effects, which may be associated with larger, therapeutic doses of the interferon and still achieve the therapeutic effect.
- compositions hereof can comprise amounts of interferon, which are less that those required for compositions containing only interferon without succinic acid or a pharmaceutically acceptable salt thereof. Therefore, compositions comprising reduced amounts of interferon according to this invention afford compositions with reduced side effects, which may be associated with amounts of the interferon necessary to achieve the same therapeutic effects as the compositions of this invention.
- interferon resistance can be associated with a disease state such as viral disease, inflammation, or action of specific cytokine, especially IL-8.
- the disease states include, but are not limited to, hepatitis C, AIDS, and influenza.
- the desired therapeutic effects achievable through the practice of this invention include all known in the art therapeutic effects of interferon. Such effects include, but are not limited to, antiviral, antiproliferative, antitumor, antibacterial, and immunoregulatory action of interferon in mammals. Preferred therapeutic effects achieved according to this invention are antiviral and antitumor effects.
- interferon and succinic acid or a pharmaceutically acceptable salt thereof can be administered in a variety of routes including oral (e.g. through gastrointestinal tract or oral mucosa), intranasal, topical, rectal, by inhalation spray, or parenteral (e.g. subcutaneous, intravenous, or intramuscular injections).
- routes including oral (e.g. through gastrointestinal tract or oral mucosa), intranasal, topical, rectal, by inhalation spray, or parenteral (e.g. subcutaneous, intravenous, or intramuscular injections).
- parenteral e.g. subcutaneous, intravenous, or intramuscular injections.
- the administration of each can be by the same route or by different routes.
- interferon and succinic acid or a pharmaceutically acceptable salt thereof is administered orally or parenterally.
- the compounds of the invention can be administered in a wide variety of different dosage forms, i.e., they may be formulated with various pharmaceutically acceptable carriers or diluents in the form of tablets, sublingual tablets, capsules, lozenges, troches, buccal patches, hard candies, powders, spray, dry spray, aerosols, aqueous solutions, elixirs, syrups, and the like.
- Such carriers include solid diluents or fillers, sterile aqueous media and various non-toxic organic solvents, etc.
- Other suitable dosage forms for the compounds of this invention include, but are not limited to, controlled release formulations and devices well known to those who practice in the art.
- ingredients that can be used in the formulation of the present invention may include, but are not limited to, absorbents, buffering agents (such as phosphate buffer, carbonate buffer, tris buffer, tartrate buffer, borate buffer, acetate buffer, or maleate buffer), colorants, flavorants, solvents and co-solvents, coating agents, direct compression excipients, disintegrants, glidants, lubricants, opaquants, polishing agents, suspending agents, sweetening agents, anti-adherents, binders, and capsule diluents, the ingredients may also include anti-fungal preservatives, antimicrobial preservatives, clarifying agents, emulsifying agents, antioxidants, levigating agents, plasticizers, surfactants, tonicity agents, and viscosity increasing agents.
- buffering agents such as phosphate buffer, carbonate buffer, tris buffer, tartrate buffer, borate buffer, acetate buffer, or maleate buffer
- colorants such as phosphate buffer, carbonate
- the present invention is not limited in any way to specific interferon but is applicable to all such interferon now known or subsequently discovered or developed. Nonetheless, a preferred interferon for use in the methods and compositions of this invention is human recombinant interferon-alpha.
- interferon to achieve the desired therapeutic effect is within the skill of those who practice in the art having the benefit of the disclosure herein.
- interferon will be present in methods and compositions of the invention in amounts within its normal or less dosage unit and daily regimen ranges as detailed in medical literature.
- the dosage range will be from about 1 IU to about 1 *10 7 IU of interferon per subject per day.
- mammals are administered about 1 *10 ⁇ IU to about 5*10 6 IU human recombinant interferon-alpha per subject per day.
- the amounts of interferon to be employed according to this invention may be varied depending upon the condition being treated, the particular compound, and other clinical factors such as weight and condition of the human or animal and the route of administration.
- Any suitable succinic acid or a pharmaceutically acceptable salt thereof may be employed in the present invention.
- the pharmaceutically acceptable salt of the succinic acid is prepared by known methods from organic and inorganic bases.
- bases include, but are not limited to, nontoxic alkali metal and akaline earth bases, for example, calcium, lithium, sodium, and potassium hydroxide; ammonium hydroxide and nontoxic organic bases, such as triethylamine, butylamine, diethanolamine, and triethanolamine.
- Succinic acid or a pharmaceutically acceptable salt thereof will be present in methods and compositions of the invention in amounts sufficient to potentiate the therapeutic effect of interferon.
- the effective amount of succinic acid or a pharmaceutically acceptable salt thereof will typically be from about 0.1 mg to about 250 mg per kg of body per day.
- mammals are administered with about 0.1 mg to 10 mg succinic acid or a pharmaceutically acceptable salt thereof per kg of body per day.
- succinic acid or a pharmaceutically acceptable salt thereof to be employed according to this invention may be varied depending upon the condition being treated, the particular compound, and other clinical factors such as weight and condition of the human or animal and the route of administration.
- the following examples are presented to demonstrate the invention. The examples are illustrative only and are not intended to limit the scope of the invention in any way.
- the cells in triplicate cultures were treated with serial dilutions of substances and compositions of the invention for 24 h.
- the medium was then decanted, and the cultures were exposed to vesicular stomatitis virus (VSV), and incubated for 24 h to permit development of extensive cytopathology in unprotected cultures.
- VSV vesicular stomatitis virus
- the ability of interferon to inhibit virus-induced cytopathic effect was assessed in terms of end-point interferon titer.
- the interferon end-point titer was taken as reciprocals of the dilution that gave 50% cell protection in each of triplicate culture. Treatment.
- Table 1 shows that co-administration of interferon and succinate results in potentiating the antiviral effect of interferon.
- the cell protection effect achieved with the amount of interferon when administered with the effective amount of succinate is 6-fold greater than the effect achieved with the same amount of interferon without succinate.
- the desired 50% cell protection is achieved with 6-fold less interferon concentration when interferon is co-administered with succinate as compared to interferon is administered without succinate.
