Bayer Robust Study

Length of Study 1 year

Real-World Betaseron® Outcomes Study (ROBUST): A twelve-month, US prospective, observational, open-label, single-arm, multi-center outcomes study of Interferon ß-1b (Betaseron®) given every other day for relapsing forms of multiple sclerosis


Study objectives

a) To evaluate patient-reported outcomes (PROs) including satisfaction, resource utilization, treatment compliance, and days of work lost during the first year following initiation of Betaseron® therapy, or resumption of Betaseron® therapy after a lag of at least three months.


b) To record changes in functional status as measured by the Kurtzke Expanded Disability Status Scale (EDSS) as administered by the patients’ treating neurologists or appropriately trained members of their staffs.


c) To collect data on relapses and major resource utilization and on any visits to emergency departments, or urgent care facilities.


The study will consist of two major components: 1) a patient questionnaire administered over the Internet, completed at baseline and at monthly intervals for one year thereafter; and 2) neurological examinations reflecting standard of care, administered by the investigators at baseline, six months, and one year. Results of the neurological exams will be reported via electronic case report form (eCRF) and filed via the Internet. In addition, data on patient characteristics and prior treatment will be collected at baseline.


Inclusion criteria

a) Provides written informed consent to participate in the study

b) At least 18 but no more than 65 years old

e) Willing and able to provide a valid e-mail address which will be in use for the duration of the study

f) Willing and able to complete study questionnaires via the Internet

g) Has reliable Internet access for the duration of the study

c) Any use of Betaseron® within the three months prior to study entry

d) Inability to read, write, or speak the English language

e) Illness or disease other than multiple sclerosis that the investigator believes is likely to cause the patient’s death or incapacity within twelve months
