Tuohy et al. Alemtuzumab treatment of multiple sclerosis: long-term safety and efficacy. J Neurol Neurosurg Psychiatry. 2014 May 21. pii: jnnp-2014-307721. doi: 10.1136/jnnp-2014-307721.
Over a median 7-year follow-up (range 33-144 months), most MSers (52%) required just two cycles of alemtuzumab. In the remaining MSers, relapses triggered re-treatment to a total of three cycles (36%), four cycles (8%) or five cycles (1%). Using a 6-month sustained accumulation of disability definition, 59/87 (67.8%) of MSers had an improved or unchanged disability compared with baseline. By an area under the curve analysis, 52/87 (59.8%) MSers had an overall improvement or stabilisation of disability. Higher baseline relapse rate was associated with worse long-term disability outcomes, with trends for longer disease duration and older age at first treatment. Secondary autoimmunity was the most frequent adverse event occurring in 41/86 (47.7%) MSers, most commonly involving the thyroid gland.CONCLUSIONS: Alemtuzumab is associated with disease stabilisation in the majority of MSers with highly active RRMS over an average seven-year follow-up. No new safety concerns arose over this extended follow-up.
