About ValiRx

ValiRx is a biotechnology oncology focused company specialising in developing novel treatments for cancer. 

The Company's business model focuses on identifying and in-licensing early stage projects, adding value through scientific development and then out-licensing therapeutic candidates early in the development process. By aiming for early-stage value creation, the Company reduces risk while increasing the potential for realising value.

Until recently, cancer treatments relied on non-specific agents, such as chemotherapy.  With the development of target-based agents, primed to attack cancer cells only, less toxic and more effective treatments are now possible.
