About Reinventing Drug Discovery

At Regeneron, we move science to medicine because our world is meant for more.

At Regeneron, we move science to medicine because our world is meant for more. We’re building on our deep understanding of cancer biology and the immune system to transform cancer care. We face the world’s most challenging diseases head on because we want more for patients.

Regeneron is a leading biotechnology company that invents, develops and commercializes life-transforming medicines for people with serious diseases. Founded and led by physician-scientists, our unique ability to repeatedly translate science into medicine has led to numerous approved treatments and product candidates in development, most of which were homegrown in our laboratories. Our medicines and pipeline are designed to help patients with eye diseases, allergic and inflammatory diseases, cancer, cardiovascular and metabolic diseases, neurological diseases, hematologic conditions, infectious diseases and rare diseases.

Regeneron pushes the boundaries of scientific discovery and accelerates drug development using our proprietary technologies, such as VelociSuite®, which produces optimized fully human antibodies and new classes of bispecific antibodies. We are shaping the next frontier of medicine with data-powered insights from the Regeneron Genetics Center® and pioneering genetic medicine platforms, enabling us to identify innovative targets and complementary approaches to potentially treat or cure diseases.

Every day, we apply our homegrown technologies and relentless spirit to help people with serious diseases. See what drives us.

Led by science

We are the only biopharma company founded and led by physician-scientists since the beginning, more than three decades ago. From our first days, science was and remains our central guiding principle. Our leadership includes multiple Nobel Laureates and five members of the National Academy of Sciences, and we are one of the first companies to form a Science and Technology Committee as an integral component of its Board, a practice which has since become industry standard.
