Neuroprotective Potential of Cannabidiol (CBD) in Preventing Oxaliplatin (Ox)-Induced Neuropathy

Recruiting now · Early Phase 1

Conditions studied: Oxaliplatin Induced Peripheral Neuropathy in Cancer Patients, Metastatic Colorectal Cancer (CRC), Peripheral Neuropathy Due to Chemotherapy

In brief

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.
