Multi-center, randomized , double-blind, placebo-controlled , two arm parallel design study of NeuroVax™ vs. Incomplete Freund's Adjuvant ( I F A) placebo. 200 subjects with Secondary Progressive SPMS

Objectives:The primary objective is to compare between treatment groups the cumulative number of new gadolinium enhancing (Gd+) lesions on brain MRI at weeks 24, 32, 40 and 48 i n subjects with secondary progressive MS. Secondary objectives include additional MRI measurements, analyses of clinical relapses, measures of neurologic disability, immunologic evaluations, and safety.
