Abstract Details

B Cells, T Cells and Inflammatory CSF Biomarkers in Primary Progressive MS and Relapsing MS in the OBOE (Ocrelizumab Biomarker Outcome Evaluation) Trial
Multiple Sclerosis
S40 - Multiple Sclerosis: Clinical Trials (2:24 PM-2:36 PM)
008

OCR, an anti-CD20 molecule, reduces progression in MS. Less is known about biomarkers and mechanisms of anti-CD20 action in PPMS than in RMS. Presence of T1 gadolinium–enhancing lesions has been associated with higher baseline cerebrospinal fluid (CSF) NfL and serum NfL (sNfL) in PPMS and RMS and significant sNfL reductions in PPMS (ORATORIO trial, n=347; p<0.001).

To assess longitudinal changes in B cells, T cells, neurofilament light (NfL) and soluble inflammatory markers in patients with primary progressive (PPMS) and relapsing (RMS) multiple sclerosis following ocrelizumab (OCR) treatment.

Twenty-eight patients with PPMS in OBOE received 600-mg OCR infusions every 24 weeks. CSF was collected at baseline and 52 weeks. Blood was collected at baseline and 6 postdose time points. Samples were assessed for NfL (Quanterix Advantage), CXCL13 and CCL19 (immunoassay) and CSF B and T cells (flow cytometry). Data were compared with previously reported RMS data.

 

Baseline CSF B cells, T cells and CCL19 levels were indistinguishable between patients with PPMS and RMS, while CSF NfL (p=0.012) and CXCL13 (p=0.020) were decreased in patients with PPMS. PPMS CSF B cells (n=15; median percent change, −100 [IQR −100, −91.4]; p<0.001) and T cells (n=17; −63.69 [IQR −80.5, −12.9]; p=0.051) were reduced at 52 weeks post-treatment. Neither CSF NfL nor sNfL were decreased at 52 weeks overall (n=28; IQR −51.1, 51.6 and IQR −30.1, 22.5, respectively); however, NfL trended lower in 7 patients with PPMS with baseline T1 gadolinium–enhancing lesions vs those without. CSF CXCL13 levels were reduced in patients with PPMS following OCR treatment but did not achieve significance (n=28; IQR −59.1, 0; p=0.084). 

Baseline CSF B cells, T cells and inflammatory biomarkers were similar in PPMS and RMS. In PPMS, similar to RMS, CSF B and T cells and CXCL13 were reduced following OCR treatment.
