The direct anti-tumour effect of RIGVIR® is associated with oncotropism and oncolysis. Oncotropism is virus ability to recognize specific receptors on the surface of tumour cells and enter it. Oncolysis is a process of dissolution or destruction of cells, apoptosis programmed cell death, anti-angiogenesis lockup or blocking the formation of new cells and cell necrosis. Both of these processes, oncotropism and oncolysis, are selective for tumour cells and normal healthy cells are minimally, if at all, affected.
