NCT05672342

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Difference in Functional Assessment of Cancer Therapy/Gynecologic Oncology Group (FACT/GOG)-Neurotoxicity (Ntx) subscale scores

    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.

    Baseline up to week 12

Secondary Outcomes (3)

  • 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

  • Agreement to allow the use of archival tissue from diagnostic tumor biopsies
  • If unavailable, exceptions may be granted with study principal investigator (PI) approval
  • Willingness to comply with all study interventions including the use of medical cannabis and follow-up assessments
  • Age: \>= 18 years
  • Eastern Cooperative Oncology Group (ECOG) =\< 2
  • 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
  • Alanine aminotransferase (ALT) =\< 3 x ULN
  • Women of childbearing potential (WOCBP): negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
  • Agreement by females and males of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 1 months after the last dose of protocol therapy
  • +2 more criteria

You may not qualify if:

  • Concurrent use of other alternative medicines such as medical cannabis, herbal agents and high dose vitamins and minerals
  • Liver cirrhosis Child-Pugh B or C
  • Mental incapacitation or significant emotional or psychological disorder that, in the opinion of the investigators, precludes study entry (These patients may not be able to cooperate with this slightly invasive procedure or with the data collection process)
  • History of diabetic neuropathy, neuropathy related to human immunodeficiency virus (HIV), or other medical causes of chronic neuropathy in the baseline assessment including past medical history, any history of diabetes, alcoholism, and vitamin B deficiency
  • Previous medical cannabis use for any indication within 30 days of enrollment
  • Planned or actual changes in type of medications that could affect symptoms related to CIPN. New medications for the treatment of CIPN are not allowed during the study.
  • Note: Subjects need to be on stable doses of CIPN medications for 4 weeks
  • Strong inhibitors or inducers of CYP3A4
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent
  • Clinically significant uncontrolled illness
  • Diagnosis of Gilbert's disease
  • Females only: Pregnant or breastfeeding
  • Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
  • Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
