520 |a FTY720 (Fingolimod) reduces multiple sclerosis disease activity by inducing lymphopenia and inhibiting lymphocyte re-entry from lymph nodes. Peripheral lymphocyte reconstitution following drug discontinuation has been considered relatively rapid (2-4 weeks), based on short-term studies. We investigated the kinetics of lymphocyte reconstitution in MS patients in open label extension phases of FTY720 clinical trials who discontinued therapy after prolonged use (>1-5 years), and examined histological features of a mediastinal lymph node obtained from a lymphopenic FTY720 patient. Although three patients showed reconstitution of peripheral lymphocytes within the predicted timeline, two patients continued to be lymphopenic 9 and 34 months after therapy cessation. Lymph nodes from the latter patient showed preserved architecture. Notwithstanding preserved lymph node integrity, time for lymphocyte reconstitution after prolonged FTY720 therapy can be significantly greater than predicted by shorter-term studies. This is relevant for clinical decisions regarding management of patients using this therapy and for introducing alternate therapies
