简要总结
This clinical trial tests how well phytocannabinoids (cannabidiol [CBD] and tetrahydrocannbinol [THC]) work in reducing chronic chemotherapy-induced peripheral neuropathy (CIPN) in breast and colon cancer survivors. Neuropathy is the most common neurological symptom reported by cancer patients due to treatment. A variety of pharmacologic treatments have been evaluated to alleviate CIPN symptoms; however, no definitive treatment has been found to successfully treat all the symptoms of CIPN. Therefore, investigators continue to seek other possible treatment options including cannabis. Phytocannabinoids may be a particularly useful intervention for cancer patients given the limited effective treatments for CIPN. In addition, cannabis-based medicines have become tremendously popular as both cancer patients and clinicians are seeking therapies with fewer potential risks of dependency and other side effects. This trial is being done to provide cancer patients and clinicians with reliable information to help guide their use of phytocannabinoids to manage the tremendous distress and pain experienced by many cancer patients, which impacts their long-term quality of life.
详细描述
PRIMARY OBJECTIVE:
I. Assess the ability of CBD and THC:CBD to reduce CIPN symptoms as compared to placebo using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group (FACT/GOG)-Neurotoxicity (Ntx) subscale among breast and colon cancer survivors.
SECONDARY OBJECTIVES:
I. Evaluate the impact of CBD and THC:CBD as compared to placebo on quality of life using the Functional Assessment of Cancer Therapy General (FACT-G) among breast and colon cancer survivors with chronic CIPN.
II. Document the utilization of neuropathic and pain medications by cancer patients with chronic CIPN during treatment with CBD and THC:CBD as compared to placebo.

- •Ability to read and understand English for questionnaires
- •Patients must have either neuropathy >= 1 according to Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 scale or a neuropathy score of > 3 on a 0-10 scale plus a FACT/GOG-Ntx score of > 10
- •The patient's previous chemotherapy treatment must have included a taxane (paclitaxel, nab-paclitaxel, or docetaxel) or platinum (cisplatin, oxaliplatin, or carboplatin) and considered the primary cause of the neuropathy by the medical team
- •Total bilirubin =< 1.5 x upper limit of normal (ULN) (unless has Gilbert's disease)
- •Aspartate aminotransferase (AST) =< 3 x ULN

结局指标
主要结局
Difference in Functional Assessment of Cancer Therapy/Gynecologic Oncology Group (FACT/GOG)-Neurotoxicity (Ntx) subscale scores
时间窗: Baseline up to week 12
The primary analysis will compare difference in scores from the FACT/GOG-Ntx between all groups using analysis of variance, and a repeated measures analysis of variance analysis will be performed. Multivariable mixed-effects regression model which takes possible dependence of longitudinal measurements within each subject into account, will be used. In addition, a paired t-test will be utilized to compare scores between baseline and 8 and 12 weeks of treatment for each group separately.
次要结局
- Quality of life by the Functional Assessment of Cancer Therapy-General (FACT-G) scores(Up to 12 weeks)
- Utilization of neuropathic and pain medications(Up to 12 weeks)
- Incidents of adverse events(Up to 12 weeks)
