A post hoc evaluation of the shift in spasticity category in individuals with multiple sclerosis-related spasticity treated with nabiximols

Abstract Background: Over 80% of individuals with multiple sclerosis (MS) experience MS-associated spasticity (MSS). In many European countries, after failure of first-line treatments, moderate or severe MSS can be treated with nabiximols, a cannabis-based add-on treatment. Objective: This post hoc analysis assessed the shift of participants treated with nabiximols from higher (severe or moderate) to lower (moderate or mild/none) spasticity. Methods: Previously published data from two randomised controlled trials (RCTs), GWSP0604 (NCT00681538) and SAVANT (EudraCT2015-004451-40), and one large real-world study
