Dosing schedule after the first two half-dose infusions of Ocrelizumab?

Explanation:
Dosing for ocrelizumab uses a loading approach, then maintenance. The initial cycle is two 300 mg infusions given 2 weeks apart to start B-cell depletion. After that, maintenance is a single 600 mg IV infusion every 6 months. So once you’ve completed the two half-doses, the regimen switches to full-dose IV infusions on a 6-month schedule. Oral daily tablets or subcutaneous injections aren’t the approved routes for this drug, and continuing with half-doses wouldn’t provide the standard maintenance exposure needed.
