The participant must have received at least 11 doses of natalizumab in the 12 months prior to randomization with no missed doses in the 3 months prior to randomization.
* Expanded Disability Status Scale (EDSS) score <=5.5 at screening.
* No relapses in the last 12 months prior to randomization, as determined by the enrolling Investigator.

For Part 2:

* Ability of the participants to understand the purpose and risks of the study and provide signed and dated informed consent for Part 2 and authorization to use confidential health information in accordance with national and local participant privacy regulations.

Key exclusion criteria
For Part 1:

* Primary and secondary progressive multiple sclerosis (MS).
* MRI positive for Gd-enhancing lesions at screening.
* Participants for whom MRI is contraindicated (e.g., have a contraindicated pacemaker or other contraindicated implanted metal device, have suffered, or are at risk for, side effects from Gd, or have claustrophobia that cannot be medically managed).
* History of any clinically significant (as determined by the Investigator) cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic (including diabetes), urologic, pulmonary, neurologic (except for RRMS), dermatologic, psychiatric, renal, or other major disease that would preclude participation in a clinical study, in the opinion of the Investigator.
* Presence of anti-natalizumab antibodies at screening.

For Part 2:

* Participants treated with natalizumab Q6W was reverted to natalizumab Q4W by choice or as rescue treatment in Part 1.
* Participant received treatment with any MS disease-modifying therapy other than 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.
