Who We Are

Seagen is a global biotechnology company that develops and commercializes transformative cancer therapies. We’re driven by a singular mission—to make a difference for people impacted by cancer.

As an industry leader in antibody–drug conjugate (ADC) technology, we pioneered the science of harnessing antibodies designed to deliver cell-killing agents to cancer cells. Three of our four approved medicines are built on this technology.

We also focus our research efforts on novel targeted small molecule therapies. In addition, we are leveraging our expertise in empowered antibodies to build a portfolio of proprietary immuno-oncology agents.

Diversity, Equity, and Inclusion

We are a multinational multicultural company committed to diversity, equity, and inclusion. Our cutting edge therapies impact the lives of people of all races, ethnicities, ages, physical abilities, gender identities, and sexual orientations, and we work hard to have our employees reflect the people we serve.
