Ofatumumab numerically reduced ARR compared with fingolimod (rate ratio [RR]: 0.84, 95% credible interval [CrI]: 0.20–3.39), dimethyl fumarate (RR: 0.61, 95% CrI: 0.16–2.30), and placebo (RR: 0.41, 95% CrI: 0.12–1.39), but not natalizumab (RR: 1.33, 95% CrI: 0.33–5.45). In a subgroup analysis of Japanese patients only, ofatumumab reduced relapses compared with all other treatments including natalizumab. These results were limited by the lack of studies reporting direct comparisons between included treatments and by heterogenous reporting of outcome data.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>These findings, although limited by the paucity of evidence for Japanese patients, suggest that monoclonal antibody therapies (ie, natalizumab and ofatumumab) may provide improved efficacy compared with other DMTs available in Japan for patients with RMS.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10193,"journal":{"name":"Clinical and Experimental Neuroimmunology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cen3.12717","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46561966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
