Seattle Genetics Licenses Monoclonal Antibodies from CLB-Research and Development


Bothell, WA – July 18, 2001 – Seattle Genetics, Inc. (Nasdaq: SGEN) announced today that the Company has entered into an agreement to license certain monoclonal antibodies that target cancer and immunological disease from CLB-Research and Development, located in the Netherlands. Seattle Genetics will have development, manufacturing and worldwide commercialization rights to therapeutic products derived from the antibodies.

Seattle Genetics will evaluate the antibodies as therapeutic agents alone as well as apply its antibody-drug conjugate technology as a way of increasing their potency. Antibody-drug conjugates enhance the potency of antibodies through the linkage of cytotoxic drug payloads, providing a means to selectively kill cancer cells while limiting damage to normal tissue. The Company has proprietary state-of-the-art, serum-stable linkers and highly potent, synthetic cell-killing agents.

“Antibody-drug conjugates represent an emerging class of therapeutic agent,” commented Clay B. Siegall, Ph.D., President and Chief Scientific Officer of Seattle Genetics. “We are pleased to be working with CLB in licensing these promising antibodies as a means of leveraging our technology platforms and further expanding our pipeline of product candidates for the treatment of cancer.”
