Background: An antineoplastic agent, mitoxantrone (MX) is used to treat neurologic disability and/or reduce the frequency of clinical relapses in patients with secondary progressive, progressive relapsing, or worsening relapsing-remitting multiple sclerosis (MS). Based on a MEDLINE search for literature concerning the use of IV MX in patients with secondary progressive MS (SPMS), there is a paucity of data to identify the clinical characteristics of responders.
Objective: The aim of this study was to monitor the effects of IV MX in patients with SPMS and varied clinical characteristics whose condition continued to worsen despite receiving IV methylprednisolone treatment.
