Abstract: The instant invention relates to a novel method for the delivery of antitumor drugs to tumor cells by the administration of a tumor-selective antibody-.beta.-lactamase conjugate that binds to tumor cells, and the additional administration of a cephalosporin prodrug that is converted at the tumor site, in the presence of the antibody-.beta.-lactamase, to an active cytotoxic drug. According to the preferred embodiment of this invention, a cephalosporin mustard has been constructed which when cleaved by .beta.-lactamase yields a cytotoxic nitrogen mustard. The methods, antibody-enzyme conjugate, prodrugs, pharmaceutical compositions, and combinations of this invention provide for enhanced selective killing of tumor cells and are thus useful in the treatment of cancers and other tumors.

Abstract: The present invention relates to methods which utilize anti-idiotypic antibodies, or fragments thereof, for tumor immunotherapy or immunoprophylaxis. Monoclonal anti-idiotypic antibodies which recognize an idiotype present on a second antibody or on a T lymphocyte or on an immune suppressor factor which is directed against a defined tumor antigen, can be used for immunization against a tumor, for immune anti-tumor activation or inhibition of suppression, or for in vitro activation of lymphocytes to be used in adoptive immunotherapy. The anti-idiotypic antibodies, or fragments thereof, can also be used to monitor anti-antibody induction in patients undergoing passive immunization to a tumor antigen by administration of anti-tumor antibody. In another embodiment, administration of T lymphocytes which express an idiotype directed against a defined tumor antigen can be used to transfer delayed-type hypersensitivity to the tumor.

Abstract: A new chimeric plasminogen activator with high fibrin affinity was designed to bind to a fibrin clot and initiate clot destruction in the presence of thrombin, but not plasmin. The chimeric molecule has an antibody variable region having a fibrin-specific antigen binding site and a single chain urokinase region having a thrombin activation site but not a plasmin activation site. The preferred embodiment, 59D8-ScuPA-T, has an N-terminal fragment of an anti-fibrin antibody (59DB) and a C-terminal thrombin-activatable low molecular weight single-chain urokinase plasminogen activator (scuPA-T). The scuPA-T portion was obtained by deletion of two amino acids (Phe157 and Lys 158) that make up the plasmin activation site from low molecular weight single chain urokinase-type plasminogen activator (scuPA).
