“Most patients with multiple sclerosis (MS) experience spasticity as the clinical course evolves. Associated symptoms include (often painful) spasms, urinary dysfunction and sleep disturbances. THC:CBD oromucosal spray (Sativex®) is approved for symptom improvement in adult patients with moderate to severe MS-related spasticity who have not responded adequately to other antispasticity medication and who demonstrate clinically significant improvement in spasticity-related symptoms during an initial trial of therapy.

SUMMARY:

In pivotal clinical trials of THC:CBD oromucosal spray, a meaningful proportion of patients with treatment-resistant MS spasticity achieved clinically relevant improvement with active treatment versus placebo. The utility of a 4-week trial of therapy to identify patients who respond to treatment was demonstrated in an enriched-design study.

THC:CBD oromucosal spray was well tolerated in these studies, with no evidence of effects typically associated with recreational cannabis use.

In a subsequent post approval clinical trial, THC:CBD oromucosal spray had no statistically significant effect on cognition and mood compared with placebo.

Moreover, after 50 weeks’ treatment, approximately two-thirds of patients, physicians and caregivers reported improvement from baseline in spasticity based on global impressions of change.

In phase III clinical trials, approximately one-third of MS patients with treatment-resistant spasticity had a clinically relevant and statistically significant response to THC:CBD oromucosal spray.

In addition to a reduction in spasticity, responders experienced meaningful relief from associated symptoms.

THC:CBD oromucosal spray was generally well tolerated and efficacy was maintained over the longer term.

A post-approval clinical trial indicated no effect of THC:CBD oromucosal spray on cognition or mood after 50 weeks of use.”
