US Classification:
530350, 514 2, 435 681
Abstract:
The invention provides methods for enhancing efficiency of prodrugs by specifically engineered enzymes with enhanced activity towards nucleoside analogs used in cancer chemotherapy, and delivering the enzymes to specific target cells in a patient. The invention also provides modified deoxycytidine kinase (dCK) mutants with such enhanced activity. Furthermore, the invention provides antibody-conjugated enzymes that can be specifically delivered to leukemic blast cells in vivo or ex vivo.
Use Of Specifically Engineered Enzymes To Enhance The Efficacy Of Prodrugs
The invention provides methods for enhancing efficiency of prodrugs by specifically engineered enzymes with altered or enhanced activity and broader substrate specificity towards nucleoside analogs used in cancer chemotherapy, and delivering the enzymes to specific target cells in a patient. The invention also provides modified deoxycytidine kinase (dCK) mutants with such enhanced activities. Furthermore, the invention provides antibody-conjugated enzymes, pharmaceutical composition and kit containing the same, that can be specifically delivered to tumor cells.

The invention relates to a composition comprising: a stably integrating delivery vector; a modified mammalian thymidylate kinase (tmpk) wherein the modified mammalian tmpk increases phosphorylation of a prodrug relative to phosphorylation of the prodrug by wild-type human tmpk. The invention also relates to use of these compositions in methods of treatment of diseaseuuius such as graft versus host disease and cancer.
