Our approach is shaped by a long history of developing highly specialized treatments and forging close relationships with physician and patient communities. Founded as Genzyme in Boston in 1981, we rapidly grew to become one of the world’s leading biotechnology companies, recognized for our pioneering development of treatments for rare genetic disorders and our innovative contributions to medical science and biomanufacturing.
Genzyme became part of Sanofi in 2011. While continuing to focus on rare diseases, we also established ourselves as a leader in the field of multiple sclerosis. In 2016, our focus expanded to include Sanofi’s programs in oncology and immunology.
