Definitions
- the present invention relates to compositions comprising at least one bisphosphonate and at least one antifolate. More specifically, the invention relates to the use of these compositions for the treatment of arthritis, including osteoarthritis and rheumatoid arthritis.
- Arthritis ('arth' meaning joint, 'itis' meaning inflammation) actually consists of more than 100 different conditions which can range from relatively mild forms of tendonitis and bursitis, to osteoarthritis ("wear and tear” arthritis), to crippling systemic forms, such as rheumatoid arthritis. Also included within the term “arthritis” are pain syndromes like fibromyalgia and arthritis-related disorders, such as lupus, that involve every part of the body. In addition, gout is also considered a type of arthritis since it affects the joints.
- RA rheumatoid arthritis
- Osteoarthritis is the result of long-standing wear and tear on the joints that usually develops as one grows older. It involves a loss of cartilage and a change in bone constitution.
- rheumatoid arthritis is a chronic inflammatory disorder with systemic features and joint involvement that results in an erosive synovitis, cartilage degradation and joint destruction. Structural damage to the joints is predictive of long-term outcome and contributes to functional decline, disability and the need for major surgery.
- RA affects more than 2.1 million Americans, 1.5 million of whom are women. This progressive, chronic, and often crippling disease usually starts in middle age but may also occur in children and young adults
- Treatments for RA are focused on treating symptoms (e.g. joint pain, stiffness and swelling) and the underlying disease process.
- Treatments for RA symptoms include corticosteroids (e.g., prednisone) and nonsteroidal anti-inflammatory drugs (NSAIDs) (e.g., aspirin, ibuprofen, indomethacin, naproxen).

- An amide may be an amino acid or a peptide molecule attached to a molecule of the present invention, thereby forming a prodrug.
- the term "metabolite” refers to a compound to which a bisphosphonate and/or methotrexate is converted within the cells of a mammal.
- the pharmaceutical compositions of the present invention may include a metabolite of a bisphosphonate and/or methotrexate instead of bisphosphonate and/or methotrexate.
- the scope of the methods of the present invention includes those instances where a bisphosphonate and/or methotrexate is administered to the patient, yet the metabolite is the bioactive entity.
- a “prodrug” refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug.
- An example, without limitation, of a prodrug would be a compound of the present invention which is administered as an ester (the "prodrug") to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial.
- a further example of a prodrug might be a short peptide (polyam ⁇ noacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety.
- the present invention relates to a method of treating a patient with a pharmaceutical composition as described herein.
- treating does not necessarily mean total cure. Any alleviation of any undesired signs or symptoms of the disease to any extent or the slowing down of the progress of the disease can be considered treatment.
- treatment may include acts that may worsen the patient's overall feeling of well being or appearance. Treatment may also include lengthening the life of the patient, even if the symptoms are not alleviated, the disease conditions are not ameliorated, or the patient's overall feeling of well being is not improved.
- compositions described herein can be administered to a human patient per se, or in pharmaceutical compositions where they are mixed with other active ingredients, as in combination therapy, or suitable carriers or excipient(s).

- the MEC will vary for each compound but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations.
- Dosage intervals can also be determined using MEC value.
- Compositions should be administered using a regimen that maintains plasma levels above the MEC for 10-90% of the time, preferably betweeji 30-90% and most preferably between 50-90%.
- the effective local concentration of the drug may not be related to plasma concentration.
- composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.
- compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient.
- the pack may for example comprise metal or plastic foil, such as a blister pack.
- the pack or dispenser device may be accompanied by instructions for administration.
- the pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration.
