Clinical Trials

Biogen’s mission is to discover, develop and deliver innovative therapies that improve the lives of patients. We are grateful to the patients, healthy volunteers, families, hospitals and clinics that participate in the clinical trials for testing our potential therapies. Each individual’s participation contributes enormously to our understanding of disease and has the potential to benefit patients around the world.

Deciding to participate in a clinical trial requires careful consideration. In most cases, the therapies investigated in clinical trials are not yet approved by regulatory agencies like the Food and Drug Administration (FDA) in the United States. The benefits and risks of taking the treatment are not completely known. By volunteering for a clinical trial, you are helping the medical community determine whether new treatments are safe and effective.


About the clinical trial process 

Biogen is conducting numerous clinical trials in neurologic and immunologic diseases to evaluate the efficacy and safety of potential therapies.
