This strategy is designed to yield clinical data demonstrating their therapeutic utility for treating cancer and severe autoimmune diseases, and this data will be leveraged to partner these therapeutic antibodies for development and commercialization across a number of major indications in these areas. The funds will also allow us to further develop and enhance our SIMPLE Antibody™ platform and suite of complementary antibody technologies on which our pipeline of differentiated therapeutic antibodies has been created. We believe that this approach will allow arGEN-X to become an important player in the fast growing therapeutic antibody market and to generate significant value for its shareholders in a timely and efficient manner.”
