Abstract: The present invention provides methods of treating rheumatoid arthritis. The methods generally involve an intermittent dosing strategy for administering Atiprimod alone or in combination with a second therapeutic agent wherein the second therapeutic agent is selected from the group consisting of Methotrexate, gold compounds, antimalarials, cyclosporine A, leflunomide, azathioprine, sulfasalazine d-penicillamine, aurothioglucose, auranofin, or a TNF inhibitor.

Abstract: A method of treatment of inflamed, pre-cancerous or cancerous tissue or polyps in a mammalian subject is disclosed. The treatment involves administration of a composition of at least one peptide agonist of a guanylate cyclase receptor and/or other small molecules that enhance intracellular production of cGMP. The at least one peptide agonist of a guanylate cyclase receptor may be administered either alone or in combination with an inhibitor of cGMP-dependent phosphodiesterase. The inhibitor may be a small molecule, peptide, protein or other compound that inhibits the degradation of cGMP. Without requiring a particular mechanism of action, this treatment may restore a healthy balance between proliferation and apoptosis in the subject's population of epithelial cells, and also suppress carcinogenesis.
