Background Art
[0003] TNFα is the prototypical member of the tumor necrosis factor (TNF) superfamily of proteins that share the primary function of regulating cell survival and cell death. A structural feature common to all known members of the TNF superfamily is the formation of trimeric complexes that bind to and activate specific TNF superfamily receptors. By way of example, TNFα exists in a soluble and transmembrane form and signals through two receptors, called TNFR1 and TNFR2, that differ in their functional endpoints.
[0004] TNF superfamily members, including TNFα itself, are associated with a variety of physiological and pathological functions that are believed to play a role in a range of medically significant conditions. Various products that can modulate TNFα activity are already commercially available. All currently approved products are macromolecules and work by inhibiting the binding of human TNFα to its receptors. Typical macromolecular TNFα inhibitors include anti-TNFα antibodies and soluble TNFα receptor fusion proteins. They are all approved for the treatment of inflammatory and autoimmune disorders, such as rheumatoid arthritis and Crohn's disease.
[0005] Therefore, there is a need for new, potent small molecule modulators of human TNFα activity that would be beneficial in treating a variety of disorders, including: autoimmune and inflammatory disorders; neurological and neurodegenerative disorders; pain and nociceptive disorders; cardiovascular disorders; metabolic disorders; ocular disorders; and neoplastic disorders.

[0415] When used in a patient, the effective amount for this use will depend on the severity and course of the disease, disorder or condition; previous therapy; the patient's health status and response to the drugs; and the judgment of the treating physician. In one aspect, prophylactic treatment comprises administering a pharmaceutical composition comprising a compound described herein, or a pharmaceutically acceptable salt thereof, to a mammal that has previously experienced or is at risk of at least one symptom of the disease being treated and is currently in remission to prevent recurrence of symptoms of the disease or condition.
[0416] In certain embodiments where the patient's condition does not improve, the compound is administered chronically, i.e., for an extended period of time, including for the duration of the patient's life, to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition, at the physician's discretion.
[0417] Once the patient's condition improves, a maintenance dose is administered (if necessary). Subsequently, in specific embodiments, depending on the symptoms, the dosage, or the frequency of administration, or both are reduced to a level that retains the improved disease, disorder, or condition. However, in certain embodiments, if there is any recurrence of symptoms, the patient requires long-term intermittent or daily treatment.
[0418] The amount of a given agent that corresponds to such an amount varies depending on factors such as the specific compound, the disease condition and its severity, the identity of the subject or host in need of treatment (e.g., weight, sex), but is otherwise determined by the specific circumstances of the case (including, for example, the specific agent administered, the route of administration, the condition being treated, and the subject or host being treated).
[0419] Route of administration
[0420] Suitable routes of administration include, but are not limited to, oral, intravenous, rectal, aerosol, parenteral, ophthalmic, pulmonary, transmucosal, transdermal, vaginal, otic, nasal, and topical administration. In addition, parenteral delivery includes, by way of example only, intramuscular, subcutaneous, intravenous, intramedullary injection, as well as intrathecal, direct intraventricular, intraperitoneal, intralymphatic, and intranasal injection.
[0421] In certain embodiments, the compounds as described herein are applied in a local manner rather than a systemic manner, for example, via direct injection of the compound into an organ, usually in the form of a depot preparation or a sustained release formulation. In a specific embodiment, the long-acting formulation is applied by implantation (e.g., subcutaneous or intramuscular) or by intramuscular injection. In addition, in other embodiments, the drug is in the form of a targeted drug delivery system, for example, delivered in the form of a liposome coated with an organ-specific antibody. In such embodiments, the liposome is targeted to the organ and selectively absorbed by the organ. In other embodiments, the compounds as described herein are provided in the form of a rapid release formulation, in the form of an extended release formulation, or in the form of a medium release formulation. In some embodiments, the compounds as described herein are topically applied.
[0422] Pharmaceutical compositions / formulations
[0423] According to standard pharmaceutical practice, the compounds described herein are administered to a subject in need thereof, alone or in combination with a pharmaceutically acceptable carrier, excipient or diluent, in the form of a pharmaceutical composition. In one embodiment, the compounds disclosed herein can be administered to animals. The compounds can be administered orally or parenterally, including intravenous, intramuscular, intraperitoneal, subcutaneous, rectal and topical routes of administration.
[0424] In another aspect, provided herein is a pharmaceutical composition comprising a compound as described herein or a pharmaceutically acceptable salt, solvate or stereoisomer thereof and at least one pharmaceutically acceptable excipient. The pharmaceutical composition is formulated in a conventional manner using one or more pharmaceutically acceptable excipients that facilitate processing of the active compound into a pharmaceutically usable formulation. The appropriate formulation depends on the selected route of administration. A summary of the pharmaceutical compositions described herein can be found, for example, in Remington: The Science and Practice of Pharmacy, Nineteenth Edition (Easton, Pa.: Mack Publishing Company, 1995); Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania 1975; Liberman, H.
