Study Summary

This trial will compare the effects of a higher dose of ocrelizumab to the current approved dose in people with PPMS.

Who is the study for?
Adults with Primary Progressive Multiple Sclerosis (PPMS) who have specific MRI brain abnormalities, a stable neurological condition for at least 30 days before the trial, and an EDSS score between 3 to 6.5. Disease duration must be under 10 years for lower EDSS scores or under 15 years for higher scores. Women of childbearing potential must use contraception; those without reproductive potential can also join.Check my eligibility
What is being tested?
The study is testing whether a higher dose of Ocrelizumab given every six months is more effective than the approved standard dose in treating PPMS. It's randomized and double-blind, meaning participants are put into groups by chance and neither they nor the researchers know who gets which dose.See study design
What are the potential side effects?
Ocrelizumab may cause infusion reactions, infections due to weakened immune response, possible reactivation of hepatitis B if previously infected, and increased risk of cancer as seen in some patients.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Ocrelizumab Higher DoseExperimental Treatment3 Interventions
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.
Group II: Ocrelizumab Approved DoseActive Control3 Interventions
Participants will be randomized to receive a minimum of 5 treatment doses of 600 mg ocrelizumab administered by intravenous (IV) infusion every 24 weeks in the DBT phase. During the optional OLE phase, participants will be offered a higher dose of ocrelizumab (either 1200 or 1800 mg), based on their body weight at OLE baseline, 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.
