About Clinical Trials

Clinical trials are scientific studies that involve people. Most clinical trials test how effective a new potential drug, medical device, or medical technique is at improving signs or symptoms of a particular condition, OR prolonging the life of a patient with the condition. Clinical trials involve a strong collaboration between researchers, drug-makers/pharmaceutical companies, hospitals, patients, and doctors.

Ongoing Clinical Trials

There are several clinical trials in process right now that support research for GBS, CIDP, and variants. Please note that this information is intended to help patients be aware of all of their options; the Foundation is unable to endorse any clinical trials.
