Here we assess alemtuzumab's effect on FSS over 5 years. Patients received alemtuzumab at baseline and Month 12 in the core study. Patients entering an extension (NCT00930553) could receive as-needed alemtuzumab retreatment, or another disease-modifying therapy (DMT), for disease activity. EDSS was evaluated quarterly by blinded raters. 6-month confirmed FSS disability progression was defined as ≥1.0-point increase in an FSS. 393 (93%) alemtuzumab patients entered the extension; 357 (91%) remained on study through 5 years, 60% received no alemtuzumab after Month 12, and 92% received no other DMT. Over 5 years, mean cerebellar, pyramidal, sensory, and cerebral FSS did not exceed baseline; for each FSS, 71%–80% of patients were free from disability progression. Patients who received only 2 courses of alemtuzumab and no other DMT for 5 years generally had lower FSS than other patients. RRMS patients with inadequate response to prior therapy had persistent improvement/stability across multiple FSS over 5 years with alemtuzumab; most patients received no additional treatment since Month 12.Study supported by Sanofi Genzyme and Bayer Healthcare Pharmaceuticals.
