In 1998, Clay co-founded Seattle Genetics. It was a time when cancer treatments were dominated by chemotherapies that didn’t differentiate between killing cancer cells and normal cells. His vision was to improve the lives of people with cancer by developing targeted therapies to treat major unmet needs.

A scientist by training, Clay built Seattle Genetics on a foundation of scientific innovation, rigorous research and drug development practices as well as a passion for helping patients. He has guided the company to its current leadership position in the field of antibody-drug conjugates (ADCs) and in the 2011 FDA approval of our first ADC product, ADCETRIS® (brentuximab vedotin). Under a collaboration with Takeda Pharmaceutical Company, ADCETRIS is now a global brand that is approved in more than 65 countries. Seattle Genetics is also advancing a diverse pipeline of proprietary ADCs for the treatment of cancer.

Under Clay’s leadership, Seattle Genetics has entered in to multiple strategic licenses for our ADC technology, including with Astellas, Genentech (Roche), AbbVie, GlaxoSmithKline and Pfizer, that have generated more than $350 million to date. Across internal and collaborator programs, there are more than 20 ADCs in clinical development using our technology. Clay has also led Seattle Genetics’ capital-raising activities, securing more than $1.2 billion through public and private financings, including the company’s initial public offering in 2001.
