Abstract
Processes for the killing of cancerous B cells, and particularly chronic lymphocytic leukemia (CLL) cells are disclosed. In one process, cancerous B cells that do not proliferate when contacted with an immune response-enhancing agent are contacted with an amount of such an agent sufficient to cause peripheral CLL cells to undergo blast transformation and proliferation. The contacted cells are then maintained for a time period sufficient for them to die from that contact. Further contacting of those cells with a cytotoxic amount of an anti-cancer drug or cytotoxic conjugate enhances the death of those cancer cells. In another process, peripheral CLL cells that proliferate on contact with an immune response-enhancing-agent are contacted with a proliferation-inducing amount of such an agent. The contacted cells are maintained for a time period sufficient to undergo blast transformation and proliferation, and the blasts are then contacted with a cytotoxic amount of an anti-cancer drug or cytotoxic conjugate and maintained.
