The evolving role of people with MS in clinical research-Some progress but more is needed.

People with multiple sclerosis (MS) have been participants in clinical trials over many years, enabling the development and approval of many treatments for relapsing-remitting MS. Today, people with MS expect to be active collaborators in clinical trials and throughout the research and development process. Researchers and clinicians can benefit from including people with MS in all aspects of research and trials, and are urged to do so, so that we can move forward more quickly in developing needed treatments for progressive MS.
