Making new medicines for people with serious diseases

Regeneron is a leading biotechnology company that seeks to invent, develop and commercialize life-transforming medicines for people with serious diseases. Founded and led for 35 years by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to nine FDA- or EMA-approved treatments and numerous product candidates in development and under investigation, almost 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 conditions, infectious diseases and rare diseases.

Technology for now and the future

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, as well as bispecific and costimulatory antibodies. Our novel and patented “Trap” fusion protein technology creates high-affinity product candidates for many different types of signaling molecules.

Through ambitious research initiatives such as the Regeneron Genetics Center®, we are conducting one of the largest genetics sequencing efforts in the world to better understand the causes of disease. Beyond our industry leadership in biologic medicines, we are expanding our toolkit to address hard-to-treat diseases by investigating new technologies, including genetic medicine approaches such as CRISPR gene editing, gene silencing and gene therapy.
