Clay Siegall: More than Just Genetics

Clay B. Siegall, Ph.D., is the current President, CEO, and Chairman of the Board of Seattle Genetics, a company is co-founded in 1998. Dr. Siegall was inspired to pursue a career in targeted cancer therapies after a family member developed the disease. At the time, there weren’t many treatment options for cancer patients; he wanted to change that.

He founded Seattle Genetics on scientific innovation, rigorous research, and high-standard drug development practices. He wanted to find the best medical options for as many diseases as possible. What he learned was the countless advantages of targeted therapies.

Generally speaking, many pharmaceutical companies produce overall drugs. The benefits of targeted therapies outweigh general diagnosis by a long shot. Very quickly, Seattle Genetics developed an antibody-drug ADCETRIS (brentuximab vedotin). Over the years, ADCETRIS became a global brand sold in over 65 countries. Seattle Genetics also developed a diverse pipeline of proprietary ADCs.

Dr. Siegall worked at other companies before founding his own. From 1991 to 1997, he worked at the Bristol-Myers Squibb Pharmaceutical Research Institute. Before that, he worked at the National Cancer Institute, National Institute of Health. Cancer Research has always been his primary focus.

When he was 19 years old, his father developed cancer. He watched his father struggle until his death five years later. From that point, he focused all his efforts on developing better treatments and medicines for cancer patients. Until his father’s death, Clay was focused on earning a Zoology degree from the University of Maryland.

After successfully establishing Seattle Genetics, Dr. Siegall began focusing on other hobbies and pursuits. He and his company made great strides in the race to find a cure. Now, he feels comfortable letting others lead research teams while he explores other hobbies and ventures of his life.

One of those aspects is his blog. It’s not a medical blog, but a blog about things he finds interesting. Some of his latest blog posts include former NFL star Marshawn Lynch’s No. 24 jersey was the No. 1 selling jersey in May on
