Brief Summary:
This is a randomized, double blind, controlled, parallel group, multicenter study to evaluate efficacy, safety and pharmacokinetics of a higher dose of ocrelizumab per intravenous (IV) infusion every 24 weeks in participants with PPMS, in comparison to the approved 600 mg dose of ocrelizumab.

Condition or disease Intervention/treatment Phase
Multiple Sclerosis Drug: Ocrelizumab Drug: Antihistamine Drug: Methylprednisolone Phase 3

Detailed Description:
Participants will be treated for a minimum of 120 weeks in the double-blind phase. Upon positive primary results after the double-blind phase, an optional higher dose extension treatment (OLE phase) is planned for eligible participants. The OLE will be carried out for approximately 96 weeks. Participants will be followed for safety for 48 weeks thereafter. Participants whose B-cell levels still did not replete to their baseline level or the lower limit of normal (LLN), whichever is lower, will move into the B-cell monitoring (BCM) phase following the safety follow-up phase. The study will end when all participants who were not treated with an alternative B-cell depleting therapy have repleted their B-cells to the baseline value or the lower limit of normal.

Arm Intervention/treatment
Experimental: Ocrelizumab Higher Dose
Participants will be randomized to receive a minimum of 5 higher treatment doses (1200 mg or 1800 mg) of ocrelizumab administered by intravenous (IV) infusion every 24 weeks in the double blind treatment (DBT) phase. During the optional open-label extension (OLE) phase, participants will continue with their assigned dose of ocrelizumab (either 1200 or 1800 mg) for approximately 96 weeks (4 doses in total). Mandatory methylprednisolone (or equivalent) and antihistaminic drug (e.g., diphenhydramine or equivalent) will be administered approximately 30-60 minutes prior to the start of each ocrelizumab infusion.
 Drug: Ocrelizumab
The actual higher dose of ocrelizumab will be assigned to participants based on their body weight at baseline: 1200 mg (participants's body weight <75 kg) or 1800 mg (participant's body weight >/=75 kg). The first dose of ocrelizumab will be administered as two 600 mg or 900 mg intravenous (IV) infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 1200 mg or 1800 mg IV infusion every 24 weeks.

Primary Outcome Measures :
  1. 1. Reduction in cCDP sustained for at least 12 weeks, measured by time to onset of cCDP sustained for at least 12 weeks. [ Time Frame: Baseline up to approximately 4.3 years ]
    Time to onset of cCDP is defined as the first occurrence of a predefined confirmed progression event measured by EDSS, T25FWT or 9-HPT.


Secondary Outcome Measures :
  1. Time to Onset of 24-week cCDP (cCDP24) [ Time Frame: Baseline up to approximately 4.3 years ]
    Time to onset of cCDP is defined as the first occurrence of a predefined confirmed progression event measured by EDSS, T25FWT or 9-HPT.

  2. Time to Onset of 12-week CDP (CDP12) [ Time Frame: Baseline up to approximately 4.3 years ]
    CDP, defined as a sustained increase from baseline in EDSS score of >/=1.0 point in participants with a baseline EDSS score of </=5.5 or a sustained increase of >/=0.5 points in participants with a baseline EDSS score of >5.5.

  3. Time to Onset of 24-week CDP (CDP24) [ Time Frame: Baseline up to approximately 4.3 years ]
    CDP, defined as a sustained increase from baseline in EDSS score of >/=1.0 point in participants with a baseline EDSS score of </=5.5 or a sustained increase of >/=0.5 points in participants with a baseline EDSS score of >5.5.

  4. Time to >/= 20% Increase in 12-week Confirmed by Timed 25-Foot Walk Test (T25FWT) [ Time Frame: Baseline up to approximately 4.3 years ]
    The T25FWT is a performance measure used to assess walking speed based on a timed 25-foot walk. The participant is directed to start at one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly and safely as possible.

  5. Time to >/= 20% Increase in 24-week Confirmed T25FWT [ Time Frame: Baseline up to approximately 4.3 years ]
    The T25FWT is a performance measure used to assess walking speed based on a timed 25-foot walk. The participant is directed to start at one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly and safely as possible.

  6. Time to >/= 20% Increase in 12-week Confirmed by 9-Hole Peg Test (9-HPT) [ Time Frame: Baseline up to approximately 4.3 years ]
    The 9-HPT is a performance measure used to assess upper extremity (arm and hand) function. The test consists of a container containing nine pegs and a wood or plastic block containing nine empty holes. The participant is to pick up each of the nine pegs one at a time and as quickly as possible place them in the nine holes. Once all the pegs are in the holes, the participant is to remove them again one at a time as quickly as possible and replace them into the container. The total time to complete the task is recorded.

  7. Time to >/= 20% Increase in 24-week Confirmed by 9-HPT [ Time Frame: Baseline up to approximately 4.3 years ]
    The 9-HPT is a performance measure used to assess upper extremity (arm and hand) function. The test consists of a container containing nine pegs and a wood or plastic block containing nine empty holes. The participant is to pick up each of the nine pegs one at a time and as quickly as possible place them in the nine holes. Once all the pegs are in the holes, the participant is to remove them again one at a time as quickly as possible and replace them into the container. The total time to complete the task is recorded.

  8. Change from Baseline in the Multiple Sclerosis Impact Scale (MSIS 29) Score [ Time Frame: Baseline up to approximately 4.3 years ]
    The MSIS-29 is a 29-item participant-reported measure of the physical and psychological impacts of MS. Participants are asked to rate how much their functioning and well-being has been impacted over the past 14 days on a 4-point scale, from "Not at all" (1) to "Extremely" (4).

    The SDMT is a performance measure that has demonstrated sensitivity in detecting not only the presence of cognitive impairment but also changes in cognitive functioning over time and in response to treatment. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Responses will be collected orally. A four-point change from baseline is typically considered clinically meaningful.
