CONTEXT: Neuropathic pain caused by chemotherapy limits dosing and duration of
potentially life-saving anti-cancer treatment and impairs quality of life.
Chemotherapeutic neuropathy responds poorly to conventional treatments, and there
is an urgent medical need for new treatments. Recent preclinical studies
demonstrate that cannabinoid agonists suppress established chemotherapy-evoked
neuropathy. OBJECTIVES: This was a pilot trial to begin to investigate a
currently available cannabinoid agent, nabiximols (oral mucosal spray containing
cannabinoids), in the treatment of chemotherapy-induced neuropathic pain.
METHODS: A randomized, placebo-controlled crossover pilot study was done in 16
patients with established chemotherapy-induced neuropathic pain. A 0-10 point
numeric rating scale for pain intensity (NRS-PI) was used as the primary outcome
measure. RESULTS: When examining the whole group, there was no statistically
significant difference between the treatment and the placebo groups on the
NRS-PI. A responder analysis demonstrated that there were five participants who
reported a two-point or greater reduction in pain that trended toward statistical
significance and the number needed to treat was five. CONCLUSION:
Chemotherapy-induced neuropathic pain is particularly resistant to currently
available treatments. This pilot trial found a number needed to treat of five and
an average decrease of 2.6 on an 11-point NRS-PI in five "responders" (as
compared with a decrease of 0.6 with placebo) and supports that it is worthwhile
to study nabiximols in a full randomized, placebo-controlled trial of
chemotherapy-induced neuropathic pain.
