The mean number of natalizumab infusions before discontinuation was 28 (range 12-72). The mean follow-up after CTX was 9 months (range 3-20 months) and the mean cumulative dose of CTX was 3731 mg/m2. Only two patients experienced a clinical relapse after 2 and 3 monthly pulses of CTX. No patients had rebound. Only one out of 15 patients showed MRI disease activity. EDSS was stable at the end of follow-up. Only 2 patients developed serious adverse events (SAE): 1 pneumonia and 1 urinary tract infection. Notably, 10/13 patients who had delayed introduction of cyclophosphamide (washout >3 months) had MS disease reactivation with rebound features in 7 patients. Conclusion. These preliminary data show that CTX could be able to reduce disease reactivation after natalizumab discontinuation. This approach must be studied in a large sample of patients for better define the treatment safety and in particular the risk of PML after natalizumab.Disclosure: Dr. Capobianco has received personal compensation for activities with Biogen Idec, Sanofi-Genzyme, Novartis, Merck Serono, and Teva as a consultant and/or speaker.
