Brief 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.


Condition or disease Intervention/treatment Phase
Chemotherapy-induced Peripheral Neuropathy Drug: medical cannabis Not Applicable

Detailed 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.

Arm Intervention/treatment
Experimental: medical cannabis
All patients will start with 250mcg cannabis flos BID and will follow the titration plan of dose modification according to CIPN relief and adverse events. Maximum dose of 2,000mcg per day is prescribed at the end of titration period, which is continuous for 15 days (about 2 weeks).On 10 weeks visit all patients will be discontinued from the treatment. In case of worsening of neuropathy at any point during the 4 weeks of FU, patients might be able to restart with inhaled MC treatment for no more than 4 weeks. Total treatment in this study will be for no more than 14 weeks.
Drug: medical cannabis
inhalation by using a Portable Metered-Dose Cannabis Inhaler
Other Name: medical marijuana




Primary Outcome Measures :
  1. Changes in the level of 150 different endocannabinoids. [ Time Frame: Determined on blood samples collected during the 4 months of participation in the study ]
    Circulating endocannabinoids concentrations .


Secondary Outcome Measures :
  1. Changes from the baseline of neuropathic pain during medical cannabis treatment . [ Time Frame: during 4 months of participation in the study ]
    Neuropathic pain detected by DN4 questionnaire .

  2. Changes in Quality of life by FACT-GOG-Ntx [ Time Frame: This exam will be performed every visit.during 4 months of participation in the study ]
    Changes of Quality of life will be evaluated by Functional Assessment of Cancer Therapy - Gynecologic Oncology Group-Neurotoxicity ( FACT-GOG-Ntx) questionnaire

  3. Changes in Quality of life by BPI [ Time Frame: This exam will be performed every visit.during 4 months of participation in the study ]
    Changes of Quality of life will be evaluated by BRIEF PAIN INVENTORY (BPI) tool.
