Abstract: A method of preparing an antibody suitable for use in an equine is provided. Also provided are equinised antibodies which specifically bind to equine neuronal growth factor (NGF) and neutralise the ability of equine NGF to bind to the p75 or TrkA equine NGF receptor. The invention extends to nucleic acids encoding same and to methods of treating pain and arthritis in an equine using said antibodies and/or nucleic acids.

Abstract: A method of preparing an antibody suitable for use in a canine is provided. Also provided are caninised antibodies which specifically bind to canine neuronal growth factor (NGF) and neutralise the ability of canine NGF to bind to the p75 or TrkA canine NGF receptor. The invention extends to nucleic acids encoding same and to methods of treating pain and arthritis in a canine using said antibodies and/or nucleic acids.

Abstract: A method of preparing an antibody suitable for use in a canine is provided. Also provided are caninized antibodies which specifically bind to canine neuronal growth factor (NGF) and neutralize the ability of canine NGF to bind to the p75 or TrkA canine NGF receptor. The invention extends to nucleic acids encoding same and to methods of treating pain and arthritis in a canine using said antibodies and/or nucleic acids.

Abstract: A method of preparing a canine antibody suitable for use in the therapeutic treatment of a canine is provided. In particular, there is provided immunoglobulins which can be selected for the characteristic of whether they mediate downstream complement mediated immune activation when bound to a target antigen. Canine derived antibodies comprising specific heavy chain isotypes are provided. The invention extends to the use of the immunoglobulins of the invention in methods of treating conditions such as pain, inflammatory conditions and cancerous conditions in a canine.

Abstract: A chimeric fusion polypeptide is provided comprising an extracellular domain of a canine TNF receptor p60 or p80 polypeptide conjoined to an Fc region of a canine IgG immunoglobulin heavy chain. The chimeric fusion polypeptide may be used in the treatment or prevention of conditions in canines mediated by TNF expression.
