International Guillain-Barré Syndrome Outcome Study (IGOS)
The international GBS Outcome Study (IGOS) is the largest and longest prospective trial designed to collect extensive data from patients afflicted with GBS in a systematic manner. The aim is to collect information from patients by intensive international collaboration. All patients are followed at standard intervals from the earliest phase of the disease up to at least one year after. At these time points all patients are clinically examined and documented according to the same protocol. The data generated from IGOS may fundamentally change how we care for patients with GBS and hasten research for more effective therapies.
The GBS|CIDP Foundation International is currently funding the IGOS trial through a research grant.
