Expertise: Restatement of Cancer Pharmacology: Improving Anticancer Drugs

Summary of Research Activities
Alkylating agents are one of the major classes of anticancer drugs. My laboratory has been attempting to improve the efficacy (therapeutic index) of alkylating agents in cancer for the past 20 years. In order to do this we have taken two opposite approaches: (a) My laboratory has developed a new alkylating agent with selective killing of glioma (brain tumor) cells. This selective anticancer agent called SarCNU specifically accumulates inside tumor cells that express transporters such as the organic cation transporters. There is an entire class of these transporters which are now being characterized. SarCNU was tested in patients in a Phase I trial at the McGill Translational Research Centre in the Jewish General Hospital. This has resulted in a publication. Currently Phase II trials are ongoing with the drug. (b) My laboratory has determined that DNA repair is a pivotal factor in chlorambucil drug resistance in chronic lymphocytic leukemia. Most recently we have been investigating the activity of RAD51 related homologous recombinational repair. We have demonstrated that this type of repair is important in chlorambucil drug resistance in chronic lymphocytic leukemia and probably in epithelial cancers. We are currently examining the ability of Gleevec, a drug utilized in the treatment of chronic myelogenous leukemia, to decrease chlorambucil drug resistance in chronic lymphocytic leukemia.
