Topical Cannabidiol for the Treatment of Chemotherapy-Induced Peripheral Neuropathy
Study Details
Study Description
Brief Summary
This clinical trial compares topical cannabidiol to placebo in improving chemotherapy-induced peripheral neuropathy, or painful sensations in your hands or feet due to chemotherapy. Peripheral neuropathy is a nerve problem that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. It usually begins in the hands or feet and gets worse over time. Peripheral neuropathy caused by chemotherapy is called chemotherapy-induced peripheral neuropathy (CIPN). CIPN is commonly seen in patients receiving certain chemotherapy medications and is hard to treat. Medications commonly used to treat CIPN have limited benefits and may cause significant side effects. A small report showed that topical cannabidiol may help treat neuropathy in patients with diabetes. This study is being done to determine if cannabidiol cream can help improve the symptoms of CIPN.

Detailed Description
PRIMARY OBJECTIVES:
-
To evaluate whether topical cannabidiol (CBD) improves CIPN, compared to placebo.
-
To evaluate side effects from topical CBD cream use, compared to placebo.
SECONDARY OBJECTIVES:
-
Other measures of neuropathy as measured by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) CIPN20 motor subscale, the EORTC QLQ CIPN20 autonomic scale, and the total Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale.
-
Adverse event profiles will also be assessed using symptom questionnaires and CTCAE version (v)5.0.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients apply cannabidiol cream topically to affected areas twice daily (BID) for 14 days. Patients then apply placebo cream topically to affected areas BID for 14 days.
ARM II: Patients apply placebo cream topically to affected areas BID for 14 days. Patients then apply cannabidiol cream topically to affected areas BID for 14 days.

Outcome Measures
Primary Outcome Measures
- Change in chemotherapy-induced peripheral neuropathy (CIPN) [Baseline to end of week 2]
CIPN will be measured by the sensory subscale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-CIPN20 which is composed of 9 individual items. Will be compared between arms using two-sample, two-sided t-tests. The cannabidiol arm will be compared to the placebo arm. Will construct 95% confidence intervals for the mean difference in sensory neuropathy score between arms. Repeated measures mixed models will be applied to the sensory scores over all time points to determine longitudinal effects and to adjust for confounding factors. Graphical results will include profile plots over time, stream plots of individual changes over time, and forest plots of the 95% confidence intervals by arm.
Secondary Outcome Measures
- Change in EORTC QLQ CIPN20 motor subscale [Baseline to end of week 2]
Will be compared between arms using two-sample, two-sided t-tests. The cannabidiol arm will be compared to the placebo arm. Will construct 95% confidence intervals for the mean difference in sensory neuropathy score between arms. Repeated measures mixed models will be applied to the sensory scores over all time points to determine longitudinal effects and to adjust for confounding factors. Graphical results will include profile plots over time, stream plots of individual changes over time, and forest plots of the 95% confidence intervals by arm.
- Change in EORTC QLQ CIPN20 autonomic scale [Baseline to end of week 2]
Will be compared between arms using two-sample, two-sided t-tests. The cannabidiol arm will be compared to the placebo arm. Will construct 95% confidence intervals for the mean difference in sensory neuropathy score between arms. Repeated measures mixed models will be applied to the sensory scores over all time points to determine longitudinal effects and to adjust for confounding factors. Graphical results will include profile plots over time, stream plots of individual changes over time, and forest plots of the 95% confidence intervals by arm.
- Total Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale [Up to 14 days]
Will compare the incidence and maximum (worst) values between arms. Fisher's exact tests will be used to compare incidence rates and Wilcoxon rank-sum tests will be used to compare maximum values between arms.
- Incidence of adverse events [Up to 28 days]
Will be assessed using symptom questionnaires and CTCAE version 5.0. Will compare the incidence and maximum (worst) values between arms. Fisher's exact tests will be used to compare incidence rates and Wilcoxon rank-sum tests will be used to compare maximum values between arms.
