BackgroundChemotherapy-induced peripheral neuropathy (CIPN) is a significant side effect of cancer treatment, potentially leading to early cessation of chemotherapy, enduring symptoms and long-lasting disability. Evidence from preclinical and clinical studies suggests that duloxetine, a serotonin-noradrenaline reuptake inhibitor, may be effective in the symptomatic treatment of CIPN. This double blind, placebo controlled, phase II randomised cross-over trial aims to determine whether treatment with duloxetine results in a reduction in chronic neuropathic symptoms experienced as a result of neurotoxic chemotherapy treatment.Methods/DesignParticipants who have received neurotoxic chemotherapy and experience daily symptoms as a consequence of peripheral neuropathy will be randomly allocated to control or experimental group with a 1:1 allocation, stratified by chemotherapy type. The primary endpoint will be patient-reported CIPN symptoms, as assessed via the FACT/GOG-Ntx. As a secondary objective, the trial will investigate whether duloxetine improves neurophysiological parameters and functional status in patients who have received neurotoxic chemotherapy treatment.DiscussionThis trial will investigate the effectiveness of duloxetine in reducing neuropathic symptoms following chemotherapy treatment, and aims to provide insight into the mechanisms underlying the symptomatic relief that duloxetine may provide. These results will be informative in advancing clinical knowledge regarding the treatment of CIPN.Copyright © 2018 Elsevier Inc. All rights reserved.
