About Seattle Genetics

Seattle Genetics was built on a foundation of rigorous research and drug invention practices, scientific innovation as well as the passion for helping patients. Dr. Siegel has led the company to its present position as a leader in inventing antibody-drug conjugates [ADCs] for cancer treatment. Under his management, Seattle Genetics has managed to enter into many strategic licenses for its anti-drug conjugates technology, including with AbbVie, Genentech[Roche], Pfizer and GlaxoSmithKline, which have brought in more than $300 million. Across collaborator and internal programs, more than 20 ADCs are currently using Seattle technology in clinical development. Dr. Siegel has also influenced the company’s capital-raising activities, obtaining more than $675 million from private and public financings, including Seattle Genetics’ initial public offer in 2001.

Seattle Genetics is fast-growing, and it is trying to enlarge its drug scope with new medicines and widen the use of the initial ones. The company also plans to embark on another hiring spree. These moves point to the company’s aggressive nature and underscore its role as the center for cancer research.

The company is testing its only commercialized drug- Adcetris, in numerous cancer-treatment scenarios. Currently, it is being tried out in over 70 trials against different types of lymphomas.

The company also intends to get another drug, known as 33A, into Phase 3 of this year’s clinical trials. The drug will be used for the treatment of acute myeloid leukemia. Also, Seattle Genetics has two drugs that treat bladder cancer and one drug for breast cancer.
