endocrinologic, hematologic, hepatic, immunologic, metabolic (including diabetes),
urologic, pulmonary, neurologic (except for RRMS), dermatologic, psychiatric, renal,

For Part 2:

- Participants treated with natalizumab EID was reverted to natalizumab SID by choice or
as rescue treatment in Part 1.

natalizumab in Part 1 or in the period between Part 1 and Part 2.

- History of human immunodeficiency virus or history of other immunodeficient
conditions.

- Current enrollment or a plan to enroll in any interventional clinical study in which
an investigational treatment or approved therapy for investigational use is
administered within 30 days (or 5 half-lives of the agent, whichever is longer) prior
to the Baseline Visit or at any time during this study.

- Inability to comply with study requirements.

- Other unspecified reasons that, in the opinion of the Investigator or Biogen, make the
participant unsuitable for enrollment.

The inclusion and exclusion criteria for new participants who did not participate in Part 1
of the study are the same as those for participants who did participate in Part 1.

Summary
Brief summary
Part 1: The primary objective is to evaluate the efficacy of natalizumab extended interval
dosing (EID) in participants who have previously been treated with natalizumab standard
interval dosing (SID) for at least 12 months, in relation to continued SID treatment. The
secondary objectives is to evaluate relapse-based clinical efficacy measures, disability
worsening, additional Magnetic resonance imaging (MRI)-lesion efficacy measures and safety of
EID in participants who have previously been treated with natalizumab SID for at least 12
months, in relation to continued SID treatment.

Part 2: The primary objective is to evaluate participant preference for subcutaneous (SC)
versus intravenous (IV) route of natalizumab administration. The secondary objectives is to
evaluate treatment satisfaction, drug preparation and administration time, safety and
immunogenicity, efficacy and characterize pharmacokinetic (PK) and pharmacodynamic (PD) drug
preparation and administration time of SC versus IV routes of natalizumab administration.
