Here is My Question:
What is the main difference between Rituxan and Ocrevus for people with PPMS?
Both drugs target the CD20 molecule on B cells and lead to B cell depletions. Rituxmab has a mouse based protein backbone and Ocrelizumab has a humanized backbone. Ocrelizumab is the only one of the two which has received FDA approval for PPMS.
