Summary

This is a randomized, double blind, controlled, parallel group, multicenter study to evaluate efficacy, safety and PK of a higher dose of ocrelizumab per intravenous (IV) infusion every 24 weeks (Q24W) in participants with PPMS, in comparison to the approved 600 milligrams (mg) dose of ocrelizumab.

Conditions

Interventions

DRUG

Ocrelizumab

The actual higher dose of ocrelizumab will be assigned to participants based on their body weight at baseline: 1200 mg (body weight \<75 kg) or 1800 mg (body weight ≥ 75 kg). The first dose of ocrelizumab will be administered as two 600 mg or 900 mg IV infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 1200 mg or 1800 mg IV infusion Q24W. During the optional OLE phase, participants will continue with their assigned dose of ocrelizumab (either 1200 or 1800 mg) for approximately 96 weeks (4 doses in total)

DRUG

Ocrelizumab

Ocrelizumab will be administered at a dose of 600 mg Q24W. The first dose of ocrelizumab will be administered as two 300 mg, IV infusions given 14 days apart. For the subsequent doses, ocrelizumab will be administered as a single 600 mg IV infusion Q24W.

DRUG

Antihistamine

Premedication with oral or IV antihistaminic drug (i.e., diphenhydramine 50 mg or an equivalent dose of an alternative) will be administered prior to each ocrelizumab infusion.

DRUG

Methylprednisolone

Premedication with 100 mg of methylprednisolone (or equivalent) will be administered by IV infusion prior to each ocrelizumab infusion.
