The vaccine works -- he hopes -- by targeting something called a heat-shock protein, which is produced in high quantity by tumor cells.

CNN: Vaccine may shift odds against deadly brain cancer

The second Chi-Med drug in trials, a radiosensitizer for head and neck cancer, helps make tumor cells more receptive to radiation by increasing the amount of oxygen in the cells.
