Oxaliplatin Induced Peripheral Neuropathy in Cancer Patients

The goal of this prospective, multicenter, observational cohort study with longitudinal blood sampling and standardized neurological evaluation over 6 months is to identify biomarkers to predict the overall occurrence of chronic chemotherapy-induced peripheral neuropathy (CIPN, any grade), in each of two treatment subgroups (taxanes and oxaliplatin). It involves integration of clinical data and plasma multiomic biomarkers (proteomic + metabolomic panel) analyzed via supervised machine learning to identify predictive features of CIPN.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and often persistent adverse effect of oxaliplatin- and paclitaxel-based chemotherapy. While exercise is frequently recommended for patients with CIPN, it remains unclear whether exercise mitigates neuropathic injury itself or primarily improves physical function and quality of life. This randomized controlled trial evaluates the effects of exercise on CIPN during and after chemotherapy. Patients receiving oxaliplatin for colorectal cancer or paclitaxel for gynecologic cancer are randomized to an exercise intervention or usual-care control. Neuropathy severity is assessed using objective neurophysiological measures, blood biomarkers, and validated clinical and patient-reported outcomes.

This is a pilot, prospective, randomized study evaluating the feasibility and acceptability of incorporating hemp-derived cannabidiol (CBD) supplementation to prevent oxaliplatin-induced peripheral neuropathy (OIPN) in patients receiving oxaliplatin-based chemotherapy for colorectal cancer (CRC). Participants will be randomized to receive either CBD capsules in addition to standard therapy or standard therapy alone.
