Abstract (en)

[origin: WO9100108A1] Enzyme-immunoconjugates which can be used for therapeutic purposes without significant patient side effects due to their administration. The general type of enzyme-immunoconjugate is composed of any antibody or fragment thereof linked to an oxidase whose natural substrate is not normally present in the body fluids or otherwise available in the extracellular spaces of the body. The therapeutic action of such oxidases lies in their ability to produce the cytotoxic yet biologically rapidly degrading agent hydrogen peroxide. Such oxidase-immunoconjugates would be specifically targeted to the desired tissues by use of the antibody component but would not be active until such time as a substrate of exogenous source is administered to the patient, whereupon hydrogen peroxide would be produced by the enzymatic process wherever the oxidase-immunoconjugate is present.
