Our therapeutic areas

We develop medicines for serious medical conditions with few or no treatment options. Every day, we work to bring patients better outcomes and advance their standard of care. 

Gaining insight through clinical trials

Biogen conducts clinical trials to assess new treatments and to investigate potential new uses and benefits for existing therapies.
