Abstract
AIM: To assess the efficacy, safety, and tolerability of oromucosal nabiximols cannabinoid medicine as adjunct therapy for children with spasticity due to cerebral palsy/traumatic central nervous system injury with inadequate response to existing treatment.
METHOD: Overall, 72 patients (mean [SD] age 12y 4mo [3y 1mo], range 8-18y) were randomized at a ratio of 2:1 to receive nabiximols (n=47; 29 males, 18 females) or placebo (n=25; 15 males, 10 females) for 12 weeks (12 sprays/day max. based on clinical response/tolerability). The primary outcome was change from baseline in level of spasticity on a 0 to 10 Numerical Rating Scale (NRS), assessed by the primary caregiver at 12 weeks. Secondary outcomes included additional measures for spasticity, sleep quality, pain, health-related quality of life, comfort, depression, and safety.
RESULTS: There was no significant difference in the spasticity 0 to 10 NRS between nabiximols versus placebo groups after 12 weeks. No statistically significant differences were observed for any secondary endpoint. Adverse events were predominantly mild or moderate in severity; however, three cases of hallucinations were reported.
INTERPRETATION: Nabiximols was generally well tolerated; however, neuropsychiatric adverse events were observed. No significant reduction in spasticity with nabiximols treatment versus placebo was observed.
WHAT THIS PAPER ADDS: Oromucosal nabiximols is generally well tolerated by paediatric patients. However, three cases of hallucinations were observed, one of which involved auditory hallucinations and a suicide attempt. Oromucosal nabiximols versus placebo did not reduce cerebral palsy/central nervous system injury-related spasticity.
