Objective:The phase IIIb VELOCE study (NCT02545868) assessed responses to selected vaccines in ocrelizumab (OCR)-treated patients with relapsing multiple sclerosis.Methods:Patients were randomized 2:1 into Group OCR (n=68; OCR 600mg); or Control (n=34; interferon-β or no disease-modifying therapy). All received tetanus toxoid (TT)-containing vaccine, Pneumovax® (23-PPV) and keyhole limpet hemocyanin (KLH). Group OCR was subdivided into OCR1 (n=33) and OCR2 (n=35) at randomization. OCR1 received Prevnar® (13-PCV) 4 weeks after 23-PPV; OCR2 and Control received influenza vaccine. Vaccinations started 12 weeks after OCR initiation (Group OCR) or on Day 1 (Control).Results:Positive response rate to TT vaccine at 8 weeks was 23.9% in OCR vs 54.5% in Control. Positive response rate to ≥5 serotypes in 23-PPV at 4 weeks was 71.6% in OCR and 100% in Control. Prevnar® did not enhance response to pneumococcal serotypes in common with Pneumovax®. Humoral response to KLH was decreased in OCR vs Control. Seroprotection rates at 4 weeks against five influenza strains ranged from 55.6–80.0% in OCR2 and 75.0–97.0% in Control.Conclusion:Peripherally B-cell depleted OCR recipients mounted attenuated humoral responses to clinically relevant vaccines and the neoantigen, KLH, suggesting use of standard non-live vaccines while on OCR treatment remains a consideration. For seasonal influenza vaccines, it is recommended to vaccinate patients on OCR, as a potentially protective humoral response, even if attenuated, can be expected.Classification of evidence:This study provides Class II evidence confirming that the humoral response to non-live vaccines in patients with RMS following ocrelizumab treatment is attenuated compared with untreated or interferon-β–treated patients, though can still be expected to be protective.ClinicalTrials.gov registry number:NCT02545868

BackgroundThe Evaluate Patient OutComes (EPOC) study assessed physician- and patient-reported outcomes in individuals with relapsing multiple sclerosis who switched directly from injectable disease-modifying therapy (iDMT; glatiramer acetate, intramuscular or subcutaneous interferon beta-1a, or interferon beta-1b) to once-daily, oral fingolimod. Post hoc analyses evaluated the impact of a switch to fingolimod versus staying on each of the four individual iDMTs.MethodsOverall, 1053 patients were randomized 3:1 to switch to fingolimod or remain on iDMT. The primary endpoint was the change in Treatment Satisfaction Questionnaire for Medication (TSQM) Global Satisfaction score. Secondary endpoints included changes in scores for TSQM Effectiveness, Side Effects and Convenience subscales, Beck Depression Inventory-II (BDI-II), Fatigue Severity Scale (FSS), Patient-Reported Outcome Indices for Multiple Sclerosis (PRIMUS) Activities, 36-item Short-Form Health Survey (SF-36) Mental Component Summary (MCS) and Physical Component Summary (PCS) and mean investigator-reported Clinical Global Impressions of Improvement (CGI-I). All outcomes were evaluated after 6 months of treatment.ResultsChanges in TSQM Global Satisfaction scores were superior after a switch to fingolimod when compared with scores in patients remaining on any of the iDMTs (all p <0.001). Likewise, all TSQM subscale scores improved following a switch to fingolimod (all p <0.001), except when compared with glatiramer acetate for the TSQM Side Effects subscale (p = 0.111). FSS scores were found to be superior for fingolimod versus remaining on subcutaneous interferon beta-1a and interferon beta-1b, BDI-II scores were significantly improved for fingolimod except for the comparison with intramuscular interferon beta-1a, and SF-36 scores were superior with fingolimod compared with remaining on interferon beta-1b (MCS and PCS; p = 0.030 and p = 0.022, respectively) and subcutaneous interferon beta-1a (PCS only; p = 0.024). Mean CGI-I scores were superior with fingolimod when compared with continuing treatment with any of the iDMTs (all p <0.001).ConclusionsAfter 6 months, a switch to fingolimod showed superiority compared with remaining on each iDMT for a range of patient- and physician-reported outcomes, including global satisfaction with treatment.Trial registrationClinicalTrials.gov NCT01216072.
