Autologous hematopoietic stem cell transplantation versus alemtuzumab in aggressive MS: a retrospective real-word study (4096)
2020
Objective: To evaluate efficacy and safety of series of aggressive relapsing-remitting (RR) MS patients treated with aHSCT and alemtuzumab in a single Italian MS center and followed for 3 years. Background: Aggressive multiple sclerosis (MS) represents almost 10% of all MS cases. Treatment of these patients is challenging and optimal strategies have yet to be defined. Alemtuzumab and autologous hematopoietic stem cells transplantation (aHSCT) represent ideal candidates for managing aggressive MS because of their profound and immediate immune-ablative effects. However, experience is limited and uncertainty remains on correct patient selection. Design/Methods: 61 patients with aggressive MS, according to the criteria of Rush et al. [CA Rush et al. Nat Rev Neurol 2015], were retrospectively collected from the MS center of Genova. 32 patients underwent treatment with alemtuzumab and 29 with aHSCT (conditioning regimen: carmustine/etoposide/ara-C/melphalan (BEAM) or cyclophosphamide). The proportion of patients with complete disease remission (no evidence of activity -NEDA-) was calculated at 3 years. Results: At baseline, aHSCT patients were younger than alemtuzumab patients (t=2.16; p=0.035), had higher EDSS (Mann-Whitney U=106; p Conclusions: Intense immunosuppression followed by aHSCT is superior to alemtuzumab in reducing relapses and MRI activity in aggressive MS and promotes disability improvement.
