BENEFIT 11 a Long-term Follow-up Study of the BENEFIT (Betaferon/Betaseron in Newly Emerging Multiple Sclerosis for Initial Treatment, 304747), BENEFIT Follow-up (305207) Studies and BENEFIT Extension (311129) Study to Further Evaluate the Progress of Patients With First Demyelinating Event Suggestive of Multiple Sclerosis
This study assesses clinical and imaging long-term data, after early or delayed interferon-beta-1b treatment in patients with a first demyelinating event suggestive of multiple sclerosis (MS), 11 years after enrollment in the Betaferon/Betaseron in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) study (304747). The main objectives are to describe the disease course, change in disability, cognitive function, resource use and employment status, in relation to Interferon beta-1b in the long term.
As optic coherence tomography (OCT) and magnetic resonance imaging (MRI) studies are essential to standardize the procedures and assessments for all OCT and MRI test centers that may take part in this study, 122 additional volunteers will be enrolled to test the dummy scans of OCT and MRI, only.
