The two drugs are completely different in their mechanism of action. Erbitux is usually not used as a mono therapy by itself. It is a monoclonal antibody, (read more about targeted therapies on the main site) and interrupts a particular function of the cell life cycle. (Reproduction) Cisplatin is a poison, it kills everything. So since cancer cells divide and replicate much faster than normal cells, wouldn't it be cool if you could interfere with that ability while you were killing the crap out of them so there were fewer that you had to kill, and perhaps less time that you had to spend doing so? If you put Erbitux and Cisplatin or another poison together, this is essentially what you have done.
