Clinical Trial Summary

Chemotherapy-induced peripheral neuropathy (CIPN) is the most common neurological cancer treatment complication. Medical cannabis is indicated in Israel for the treatment of chronic pain, spasticity and for the control of pain and other symptoms in patients with cancer.

The proposed study aims are to study about the changes in level of endocannabinoids following continuous exposure to phytocannabinoids and about the long-term effect of medical cannabis on CIPN.

Description:

This will be a self-titrated, open-label design study. Subjects who begin taxanes or oxaliplatine therapy and were diagnosed with CIPN will be recruited to the study.

After providing their written informed consent, the study physician obtained a medical history, demographic details and conducted a physical examination. During the current study, baseline period for CIPN evaluation will be 2 weeks, while patients will fill several questionnaires. Baseline CIPN will be evaluating by DN4 and BPI questionnaires. EQ-5D and PSQI will be filled for baseline Quality of life (QOL) and sleepiness status, accordingly.
