Reinventing Drug Discovery

For over 30 years, our mission has been to use the power of science to bring new medicines to patients… over and over again.

Regeneron (NASDAQ: REGN) is a leading biotechnology company that invents life-transforming medicines for people with serious diseases. Founded and led for over 30 years by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to nine FDA-approved treatments and numerous product candidates in development, nearly all 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, pain, hematologic diseases, infectious diseases and rare diseases.

Regeneron is accelerating and improving the traditional drug development process through our proprietary VelociSuite® technologies, such as VelocImmune®, which uses unique genetically humanized mice to produce optimized fully human antibodies and bispecific antibodies, and through ambitious research initiatives such as the Regeneron Genetics Center®, which is conducting one of the largest genetics sequencing efforts in the world.

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.
