However, we noted no change in the number of LME following IT rituximab over the 24-week MRI follow up. We observed transient reductions in CSF B cells (p=0.018) and CXCL-13 levels (p=0.045) with an increase in BAFF levels (p=0.17) with treatment.Conclusions: IT rituximab was well tolerated in PMS patients and resulted in profound peripheral B cell depletion. IT rituximab had transient effects on CSF biomarkers but did not change LME detected on imaging. IT rituximab was insufficient to completely resolve meningeal inflammation in this small PMS cohort.Study Supported by: Grant from Race to Erase MS and Progressive MS Alliance to PC.
