Abstract: The present invention provides a method for determining a sequence to administer multiple types of chemotherapeutic drugs for killing cancerous cells to reduce the induction of drug cross-resistance in a patient. The methods also involves screening drug candidates to select a lead anticancer drug from amongst a plurality of candidate drugs, the lead having a reduced capacity to induce cross resistance in a patient against one or more known anticancer drugs, and all of the drugs having the ability to kill cancerous cells of the same selected tumour type. Moreover, the methods involve determining a sequence to administer multiple types of cytotoxic drugs for killing undesired cells to reduce the induction of drug cross-resistance in the cells.

Abstract: Calphostin C is used to treat subjects for cancer which is resistant to treatment by other forms of chemotherapeutic drugs, for example breast or uterine cancer, or other cancers characterized by tumor cells that have a defect in an apoptotic regulatory pathway which renders said cells resistant to at least some other forms of chemotherapeutic treatment. The other chemotherapeutic drug used with calphostin C is selected from the group comprising taxanes and anthracyclines, such as paclitaxel or doxorubicin. The use may take the form of administering calphostin C and then subjecting the patient to photodynamic therapy (PDT).

Abstract: The present invention provides isogenic cell lines and uses said isogenic cell lines in a method for determining a sequence to administer multiple types of chemotherapeutic drugs for killing cancerous cells to reduce the induction of drug cross-resistance in a patent. The methods also involves screening drug candidates to select a lead anticancer drug from amongst a plurality of candidate drugs, the lead having a reduced capacity to induce cross resistance in a patient against one or more known anticancer drugs, and all of the drugs having the ability to kill cancerous cells of the same selected tumour type. Moreover, the methods involve determining a sequence to administer multiple types of cytotoxic drugs for killing undesired cells to reduce the indication of drug cross-resistance in the cells.
