Chosa Oncology 

A biotechnology company conducting research and development within immunotherapy, on therapeutic cancer vaccines.

Chosa Oncology concept focuses on eliminating metastatic cancer cells that may escape treatment of the parent tumour via other methods. Because RhoC is not expressed in the parent tumour, the company goal is to use the developed product in combination with another therapy — specifically, treatment of the parent tumour by e.g. surgery, radiotherapy or chemotherapy, followed by treatment with the therapeutic cancer vaccine to combat metastasis.
