A Phase IIIB, Multicenter, Randomized, Parallel-Group, Open-Label Study to Evaluate the Effects of Ocrelizumab on Immune Responses in Patients With Relapsing Forms of Multiple Sclerosis
This multicenter, randomized, open-label study will evaluate the immune response to vaccines (tetanus toxoid [TT]-containing adsorbed vaccine, 23-valent pneumococcal polysaccharide vaccine [23-PPV] either unboosted or boosted with 13-valent pneumococcal conjugate vaccine [13-PCV], influenza vaccine, keyhole limpet hemocyanin [KLH]) after administration of a dose of ocrelizumab (OCR) in participants with relapsing multiple sclerosis (RMS).
