E.4 | Principal exclusion criteria |
1. Not previously enrolled in Study 215ON201. 2. Inability to comply with study requirements. 3. Other unspecified reasons that, in the opinion of the Investigator or Biogen, make the subject unsuitable for enrolment. 4. Subjects with recent kidney function, such as serum creatinine above upper limit of normal range, will not be allowed to receive administration of gadolinium (Gd) but will otherwise be allowed to participate in the study, including MRI assessments not requiring the use of Gd. 5. Female subjects must have had a recent pregnancy test and must not be breastfeeding prior to MRI assessments with Gd. |
