Effect of Hemp-CBD on Patients With CIPN
The purpose of this study is to assess the effect of a hemp-based cannabidiol (CBD) product, Ananda Hemp Spectrum Gelcaps, on the severity and duration of chemotherapy-induced neuropathy (CIPN) among non-metastatic breast, uterine, pancreatic, and colorectal cancer, and all stages of ovarian cancer in patients who received neoadjuvant or adjuvant therapy that included neurotoxic chemotherapeutic agents.
CIPN is a common complication of many effective cytotoxic agents that can negatively impact patients' treatment course and quality of life. The incidence of CIPN in cancer patients receiving multidrug regimens is estimated at 38%, with frequencies approaching 100% with certain known neurotoxic drug classes. Taxanes (e.g., paclitaxel, docetaxel) and platinum-based agents (e.g., oxaliplatin, cisplatin, carboplatin) in particular, are two commonly used chemotherapy classes that are associated with a high incidence of CIPN. Symptoms of chemotherapy-induced peripheral neuropathy include distal extremity numbness, tingling and pain. Chronic, cumulative symptoms can severely impact quality of life and result in dose reductions and/or drug discontinuation in up to 30% of patients. Consumers use cannabis products for various reasons including pain, stress, anxiety, and insomnia. The neuro-modulatory effects of phytocannabinoids, tetrahydrocannabinol (THC) and cannabidiol (CBD) in particular, have been documented at both the molecular and clinical level. The endocannabinoid system consists of CB1 receptors and CB2 receptors that act as an inhibitory G-protein within the central and peripheral nervous system, respectively. Several animal models have demonstrated the role endocannabinoids play in neuropathic pain development by showing enhanced neuropathic pain with CB1 receptor deletion and reduced manifestations of neuropathic pain with CB2 receptor overexpression. The therapeutic properties of cannabis-based products have also been illustrated in several randomized double-blind trials that have shown significant pain relief versus placebo in the treatment of neuropathy related to diabetes, spinal cord injury, multiple sclerosis, and HIV associated polyneuropathy. Studies specifically looking at the role of CBD in chemotherapy-induced neurotoxicity have shown a neuroprotective effect of CBD in mouse models. Studies have demonstrated that a 14-day dosing regimen of CBD prevented the onset of paclitaxel-induced mechanical and thermal sensitivity. These intriguing results suggest that cannabinoid agents could potentially reduce the severity and duration of CIPN in the clinical setting.

Arms and Interventions
| Participant Group/Arm | Intervention/Treatment |
|---|---|
| EXPERIMENTAL: Hemp-based CBD | DRUG: Hemp-based CBD
|
| PLACEBO_COMPARATOR: Placebo Oral Tablet | OTHER: Placebo oral tablet
|
| Primary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Change in pressure/touch sensation during intervention and at follow-up | At regular intervals, CIPN will be assessed by Semmes Weinstein Monofilament Examination using Touch-Test Sensory Evaluator Kit to determine pressure sensation. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in pain sensation during intervention and at follow-up | At regular intervals, CIPN will be assessed by pinprick examination to determine pain sensation. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in vibration sensation during intervention and at follow-up | At regular intervals, CIPN will be assessed by 128Hz tuning fork vibration test to determine vibration sensation. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in quality of life | Quality of life will be measured by European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 Questionnaire, a validated 30-item questionnaire to assess treatment impact on quality of life in cancer patients on 4-point scales, where 4 is most severe. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in CIPN symptom severity | CIPN symptoms will be measured by EORTC QLQ-CIPN20 Questionnaire, validated 20-item questionnaire to assess symptom severity of chemotherapy-induced peripheral neuropathy on 4-point scales, where 4 is most severe. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in pain severity | Pain severity will be measured by Brief Pain Inventory (BPI) Short Form, validated 9-item questionnaire to assess the severity of pain and the impact of pain on daily functions on 10-point scales, where 10 is most severe. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Change in sleep quality | Sleep quality will be measured by Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Questionnaire, validated 8-item questionnaire to assess sleep quality on 5-point scales, where 5 is the most severe. | Every two weeks for twelve weeks during intervention; One month follow-up |
| Secondary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Receptivity and accrual rate to clinical studies involving cannabis-based substances. | Receptivity to clinical trials as well as to the use of CBD will be assessed using a questionnaire that will be distributed to all patients at the first encounter. Responses to this questionnaire will provide information regarding in the use of CBD was influencing factor for those who chose to participate or deferring factor for those who decline participation. | 1 Day |
| Adherence to CBD Products | Adherence will be assessed with a Dosing Diary. | Daily, 12 weeks |
| Rate of side effects using medical-grade CBD concentrates | Side effects will be assessed at each encounter clinical evaluation by patient report in a Dosing Diary. All side effects thought to be secondary to CBD will be documented. | Daily, 12 weeks |
