CBG/CBD Oil for Chemotherapy-Induced Peripheral Neuropathy

The goal of this clinical trial is to learn if a commercially available cannabigerol (CBG)/cannabidiol (CBD) oil is safe, feasible to use, and can help reduce symptoms of chemotherapy-induced peripheral neuropathy (CIPN) in adults who have completed platinum-based chemotherapy for gastrointestinal cancers. The main questions it aims to answer are: Is CBG/CBD oil safe and well-tolerated over a 12-week treatment period? Can participants with CIPN use CBG/CBD oil consistently as part of their care? Does CBG/CBD oil help reduce pain, numbness, or other symptoms of CIPN? Participants will: Take CBG/CBD oil under the tongue (sublingually) twice daily for 12 weeks Complete regular symptom assessments and functional tests during study visits Provide blood samples for cannabinoid and metabolite level testing

A Virtually Delivered Diet Intervention (LASO-3) for the Improvement of Chemotherapy-Induced Peripheral Neuropathy in Cancer Survivors Post-treatment

This clinical trial studies whether a virtually delivered diet intervention focused on lower added sugar, higher fiber, and higher omega 3 fatty acid (LASO-3) can be used to improve chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors after treatment. Cancer survivors often experience CIPN during and after cancer treatment with neurotoxic chemotherapy. CIPN is characterized by nerve damage from chemotherapy that leads to numbness, tingling, or pain in the hands or feet. However, there are few treatments to manage CIPN. Inflammation contributes to the development of CIPN and dietary patterns that have been demonstrated to improve diet quality and reduce inflammation in cancer survivors may be promising for use as a CIPN management strategy. The LASO-3 diet intervention consists of virtually delivered nutrition education sessions provided by a Registered Dietitian. The sessions focus on three dietary goals, informed by the United States Dietary Guidelines for Americans: 1) lowering added sugar intake to \< 10% of daily calories, 2) increasing daily fiber intake to ≥ 20 grams, and 3) increasing intake of moderate-high omega-3 seafood to three or more servings weekly or 3300-3400 mg/day of alpha-linolenic acid (e.g., plant-based sources include canola or flaxseed oil, walnuts, or flaxseed or chia seeds). The Registered Dietitian tailors the sessions to the patient based on information and feedback obtained throughout the sessions. The LASO-3 diet intervention may be an effective way to improve CIPN in cancer survivors after treatment.

Evaluating a Mobile Health Application Intervention for Caregiver Instruction in Manual Therapy for Chemotherapy-Induced Peripheral Neuropathy

This clinical trial assesses the impact of a family caregiver-delivered massage technique for use in cancer survivors with chemotherapy-induced peripheral neuropathy (CIPN). CIPN is a common cancer treatment side effect that impairs quality of life and daily functioning. Aside from the relatively transient effects of chemotherapy treatment (e.g., nausea, diarrhea, vomiting, infections, fatigue, hair loss), chemotherapy can damage nervous system structures leading to long-term CIPN effects including numbness in hands or feet, "pins and needles" or sudden stabbing pains, difficulty buttoning clothing or picking up objects, loss of balance and risk of falling, difficulty driving (steering wheel, foot pedals), and increased sensitivity to heat or cold. Caregivers who lack effective strategies of supportive care are at risk of feeling helpless, overwhelmed or frustrated watching their loved one suffer. Oncology massage (OM) teaches oncology-informed modifications, adaptations and safety precautions for a cancer survivor's specific condition, treatment history and side effects. An mobile health application (app) for caregivers can teach care for CIPN using safe oncology-informed massage techniques at home. Using the Peripheral Neuropathy Relief (PNR) program in the form of relaxation may help for stress reduction, reduced CIPN symptoms, and/or an increased sense of connection with patients and their family caregiver.

The Use of Acupuncture to Reduce Chemotherapy Induced Peripheral Neuropathy in Gynaecological Cancer Patients

Objectives: To explore the feasibility and effectiveness of acupuncture on reducing Chemotherapy Induced Peripheral Neuropathy (CIPN) in gynaecological cancer patients who have received carboplatin and paclitaxel chemotherapy combination. Results of this pilot trial will provide preliminary information for a potential a larger scale multicentre study. Hypothesis: Acupuncture can significantly reduce CIPN in gynaecological cancer patients treated with chemotherapy Design and subjects: This is a pilot, prospective randomised controlled trial. This is an exploratory trial to evaluate the feasibility and effectiveness of acupuncture in reducing CIPN in gynaecological cancer patients. Eligible patients will be 1:1:1 randomised to three groups: electroacupuncture group, sham acupuncture group and waiting-list (usual care) control group. For electroacupuncture and sham acupuncture groups, the assessors and the patients will be blinded to the treatment given. 1. Electroacupuncture group - patients will receive 6 weeks of electroacupuncture, 2 sessions per week, by a qualified Traditional Chinese Medicine practitioner from the School of Chinese Medicine. 2. Sham acupuncture group - patients will receive 6 weeks of sham acupuncture similar to the above. 3. Waiting-list (usual care) control group - patients will not receive any treatment. Main outcomes: Acupuncture effects will be assessed at baseline and 3, 6,12 weeks post intervention by: 1. Patient reported outcome measures: FACT/GOG-Ntx questionnaire for assessing CIPN symptoms and EORTC-QLQ-C30 and CIPN20 questionnaires for assessing quality of life symptom 2. Clinician reported outcome measures: NCI-CTCAE grading for CIPN by clinicians and Semmes-Weinstein monofilament test as an objective measurement of CIPN. Data analysis: Intention to treat analysis will be carried out. Baseline demographics will be compared between the 3 groups. Change from baseline total score will be calculated and analysed using 2-sample t-test. 95% CI will be reported for treatment differences. Score for different subcategories will be analysed in a similar manner. Data collected at week 6 will be used for outcome analysis. P\<0.05 will be considered as statistically significant. Acupuncture efficacy, effectiveness and placebo effect will be indicated by comparison of acupuncture vs. sham acupuncture, acupuncture vs. waiting-list, and sham acupuncture vs. waiting-list, respectively. Expected results: Patients in the acupuncture arm will have reduced numbness and peripheral neuropathy and improved quality of life without any adverse event.

Assessing Effect of Spinal Cord Stimulation on Pain and Quality of Life With Chemotherapy-Induced Peripheral Neuropathy

This study examines how spinal cord stimulation (SCS) affects pain level and quality of life in patients experiencing chemotherapy-induced peripheral neuropathy (CIPN). CIPN is a nerve problem and one of the potential side effects of chemotherapy that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. CIPN usually begins in the hands or feet and gets worse over time. SCS is a type of therapy that has proven to be effective in treating numerous non-malignant pain disorders including failed back surgery syndrome, refractory angina, limb ischemia, complex regional pain syndrome, and diabetic peripheral neuropathy. SCS may also be useful in patients with CIPN. This study evaluates how SCS affects pain and quality of life in patients undergoing spinal cord stimulation for CIPN.

The Influence of Chemotherapy on Position Sense

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most prevalent side-effects of chemotherapy, causing sensory and motor symptoms in patients. CIPN development is especially prevalent in chemotherapy treatment involving platinum- and taxane-based agents. The accompanying pain and deficits greatly impact the quality of life of these patients. Currently, patients are assessed for altered somatosensory using quantitative sensory testing (QST). The German Research Network on Neuropathic Pain (DFNS) has developed a standardized protocol which has been internationally recognized as approach for performing the QST. However, for proprioception the QST is limited to vibration assessments, making it limited as the only test to measure proprioception. Therefore, a comprehensive assessment of the proprioceptive functions is needed to better understand the influence CIPN has on the proprioception of patients, and thereby their quality of life. In this project the effects of chemotherapy on somatosensory and proprioceptive functioning of breast cancer patients will be assessed in a cross-sectional study. This will be tested by comparing two groups of breast cancer patients and a healthy control group. Both patient groups will have undergone surgery for breast cancer, however, only one group will be tested after undergoing additional chemotherapy treatment. Thereby, the effects of chemotherapy between the surgery-only patient group and the chemotherapy patient group can tested. Furthermore, the investigators will compare both patient groups to sex- and age-matched healthy controls.

Patients Referred to the Chronic Pain Unit for Palliative Treatment With Ozone Therapy Between 2026 and 2029.

The main objective of this study is to analyze the impact on the health-related quality of life of patients with refractory symptoms who have been referred to the Dr. Negrín University Hospital Chronic Pain Unit for adjuvant palliative treatment with ozone therapy between January 2026 and December 2029. Additionally, the study aims to evaluate several specific symptoms, hyperspectral and thermal images, non-invasive clinical parameters related to the Autonomic Nervous System (such as heart rate variability, electrochemical skin conductance, and vibration perception thresholds), oxidative stress and inflammatory parameters, and gut microbiota composition.

8 Weeks vs 12 Weeks Physical Exercise Programmes in Colorectal Cancer Patients

Chemotherapy is a cornerstone in the treatment of colon cancer; however, its effects extend beyond malignant cells. Because chemotherapeutic agents target rapidly dividing cells, they can also damage healthy tissues, resulting in a range of adverse effects. Among the most prevalent is peripheral neuropathy, a disorder of the peripheral nervous system characterized by symptoms such as tingling, numbness, pain, and weakness in the extremities. Chemotherapy-induced peripheral neuropathy poses a significant challenge for patients with colon cancer, as it further compromises quality of life during an already demanding phase of treatment. Damage to sensory and motor nerves interferes with the ability to perform daily activities and diminishes physical capacity, thereby intensifying both the physical and psychological burden associated with the disease. Nevertheless, certain interventions may help mitigate these negative effects, with physical exercise emerging as a particularly promising strategy. Although it may appear counterintuitive, regular physical activity has been shown to exert beneficial effects on peripheral neuropathy. Exercise enhances blood circulation, supports the regeneration of damaged peripheral nerves, and helps reduce neuropathic pain and discomfort, ultimately improving functional performance. It is important to emphasize that exercise interventions should be individually tailored and conducted under appropriate medical supervision. Consequently, the integration of chemotherapy with a carefully designed exercise program represents a comprehensive approach to managing both the disease and its treatment-related side effects, contributing to an improved quality of life for patients with colon cancer throughout their recovery process.

Duloxetine and Neurofeedback Training for the Treatment of Chemotherapy Induced Peripheral Neuropathy

This phase II trial investigates how well duloxetine and neurofeedback training work in treating patients with chemotherapy induced peripheral neuropathy. Duloxetine is a type of serotonin and norepinephrine reuptake inhibitor that increases the amount of certain chemicals in the brain that help relieve depression and peripheral neuropathy. Neurofeedback training is a type of therapy that uses an electroencephalograph (EEG) and a computer software program to measure brain wave activity and may help teach patients with peripheral neuropathy (nerve damage) how to change their own brain waves to lower their feelings of neuropathy and help improve their overall quality of life. Giving duloxetine and neurofeedback training may work better in treating peripheral neuropathy caused by chemotherapy compared to duloxetine or neurofeedback training alone.

Phytocannabinoids for Reducing Chronic Chemotherapy-Induced Peripheral Neuropathy in Breast and Colon Cancer Survivors

This phase II trials evaluates how well different types of phytocannabinoids (cannabidiol \[CBD\] versus tetrahydrocannabinol \[THC\] and CBD formulation \[THC:CBD\]) work to reduce chronic chemotherapy-induced peripheral neuropathy among breast and colon cancer survivors. Chemotherapy induced peripheral neuropathy is a set of symptoms that includes pain, tingling, numbness and motor weakness caused by certain types of chemotherapy treatment. Phytocannabinoids are compounds made by the cannabis plant, such as THC and CBD, that have been found to be an effective treatment for chronic pain. Phytocannabinoids may be effective in reducing chronic chemotherapy-induced peripheral neuropathy symptoms in patients treated for breast or colon cancer.

Testing the Effects of Exercise on Chemotherapy-Induced Peripheral Neuropathy

This phase II trial studies whether using exercise is better than the usual approach for treating chemotherapy-induced peripheral neuropathy (CIPN). CIPN occurs when chemotherapy damages the nerves communicating between the brain, spinal cord, and the rest of the body. The usual approach for treating CIPN is treatment with drugs that help reduce symptoms of other types of neuropathy (for example, from diabetes). However, these drugs do not treat all symptoms of CIPN. Exercise may help to reduce CIPN symptoms.

PEA for the Relief of Chemotherapy-Induced Peripheral Neuropathy

This phase II trial tests whether PEA works to relieve the symptoms of chemotherapy-induced peripheral neuropathy in patients with cancer. Chemotherapy-induced peripheral neuropathy refers to a nerve problem that causes pain, numbness, tingling, or muscle weakness in different parts of the body, and is caused by chemotherapy. PEA may be useful against bothersome nerve symptoms.

Compression Stockings to Prevent Peripheral Neuropathy Caused by Antibody-Drug Conjugates in Urothelial Carcinoma Patients

This multicenter, prospective phase II clinical trial aims to evaluate the efficacy and safety of medical compression stockings in preventing peripheral neuropathy induced by antibody-drug conjugates (ADCs) containing monomethyl auristatin E (MMAE) in patients with advanced cancers, including urothelial carcinoma. Eligible participants will have no baseline ≥ grade 1 neuropathy and will be scheduled to receive MMAE-containing ADC therapy. A total of 58 patients will be enrolled and followed for 24 months. In this self-controlled design, the left foot will be fitted with a medical compression stocking while the right foot remains uncovered, starting 15 minutes before infusion and continuing until 15 minutes after infusion (total duration: 120 minutes). Peripheral neuropathy will be assessed before treatment, after cycle 3, within 1 week after treatment completion, and 1 month after completion, using CTCAE v5.0 and patient-reported questionnaires (QLQ-C30 and FACT-GOG-NTx). Toe temperature will be measured to assess local microcirculation changes. The study will also monitor compression-related adverse events. The results will provide evidence for preventive strategies to reduce ADC-induced peripheral neuropathy and improve patients' quality of life.

Transcutaneous Electrical Nerve Stimulation in Chemotherapy Induced Peripheral Neuropathy in Patients With Stage I-III Early Stage Breast Cancer

This phase II trial examines transcutaneous electrical nerve stimulation (TENS) in patients with stage I-III breast cancer with chemotherapy induced peripheral neuropathy. TENS is a procedure in which mild electric currents are applied to some areas of the skin to potentially improve neuropathy. This trial may help determine if TENS is feasible and effective for the treatment of peripheral neuropathy symptoms while on chemotherapy.
