Notes for Editors


About ValiSeek

ValiSeek Limited ("ValiSeek") is a joint venture ("JV") company between ValiRx Plc and Tangent Reprofiling Limited, part of the SEEK Group. ValiSeek was formed to progress the drug VAL401 through its remaining preclinical development and towards Phase II trials for the treatment of lung cancer and other oncology indications.


About ValiRx

ValiRx is a biotechnology oncology focused company specialising in developing novel treatments for cancer and associated biomarkers. It aims to make a significant contribution in "precision" medicine and science, namely to engineer a breakthrough into human health and well-being, through the early detection of cancer and its therapeutic intervention.


The Company's business model focuses on out-licensing therapeutic candidates early in the development process. By aiming for early-stage value creation, the company reduces risk considerably while increasing the potential for realising value. The group is already in licensing discussions with major players in the oncology field.


ValiRx's two classes of drugs in development, which each have the potential for meeting hitherto unmet medical needs by existing methods, have worldwide patent filings and agreed commercial rights.   They originate or derive from World class institutions, such as Cancer Research UK and Imperial College. 


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. New drugs in this group-such as those in ValiRx's pipeline-promise to greatly improve outcomes for cancer patients.


The Company listed on the AIM Market of the London Stock Exchange in October 2006 and trades under the ticker symbol: VAL
