Abstract: Compositions and methods for producing monoclonal antibodies and their derivatives reactive against bioactive lipid targets are described. These compositions include derivatized lipids, each of which comprises a bioactive lipid that having a polar head group and at least one hydrocarbon chain (e.g., a lysolipid such as lysophosphatidic acid or sphingosine-1-phosphate) in which a carbon atom has been derivatized with a pendant reactive group; immunogens made by linking a derivatized lipid to a carrier moiety (e.g., a carrier protein, polyethylene glycol, colloidal gold, alginate, or a silicone bead); monoclonal antibodies and derivatives produced by immunizing an animal with such an immunogen; and therapeutic and diagnostic compositions containing such antibodies and antibody derivatives.

Abstract: Methods for preventing or treating pain are provided. Such methods comprise administering to a subject (e.g., a human subject) an antibody or antibody fragment that binds LPA. The antibody may be a humanized monoclonal antibody.

Abstract: The present invention relates to compositions that comprise an anti-S1P monoclonal antibody, antibody fragment, or derivative in a carrier, particularly a buffered, hypertonic aqueous solution, as well as to kits containing such compositions, and methods for using such compositions for treatment of diseases and conditions associated with S1P.

Abstract: Compositions and methods for making and using anti-LPA agents, for example, monoclonal antibodies, are described. Variable domain and complementarity determining region amino acid sequences of several monoclonal antibodies against LPA are disclosed, as is a consensus anti-LPA monoclonal antibody variable domain sequence.

Abstract: The present invention relates to methods that involve administration of an anti-S1 P antibody or antibody fragment or derivative to a subject having or suspected of having an ocular disease or condition, including one involving choroidal neovascularization, in order to achieve a desired effect. Such effects include reducing the size of a choroidal neovascularization lesion in the eye, decreasing or resolving retinal pigment epithelial detachment, decreasing central retinal lesion thickness, and preserving or improving visual acuity. Pharmaceutical compositions comprising an anti-S1 P antibody for ocular administration are also provided. The compositions and methods are particularly useful for treating subjects having age-related macular degeneration, particularly exudative or wet age-related macular degeneration.

Abstract: The present invention relates to compositions and methods for prevention and treatment of diseases and conditions, particularly ocular diseases and conditions, characterized by aberrant fibrogenesis or scarring, inflammation, and/or aberrant neovascularization or angiogenesis. The compositions and methods of the invention utilize immune-derived moieties that are specifically reactive against the bioactive lipid, sphingosine-1-phosphate, and its variants, which moieties are capable of decreasing the effective concentration of bioactive lipid being targeted. In one embodiment, the immune-derived moiety is a humanized monoclonal antibody that is reactive against sphingosine-1-phosphate.

Abstract: Methods for designing optimized antibodies, including optimized humainized or human antibodies, to target bioactive lipids are provided. These methods may be performed in silico and may be intended to enhance binding affinity of an antibody to its original target lipid, and/or to alter binding specificity. Antibodies produced by these methods are also provided, as are methods for using them.
