What is the purpose of this trial?

This trial aims to determine how cannabis might help cancer patients with pain, sleep, and mood issues. It will compare two types of CBD (cannabidiol) treatments: one with THC (a compound that can cause a "high") and one without, against a placebo. The goal is to assess whether these treatments can improve quality of life and how they affect cognitive function, including thinking and memory. Suitable candidates include those with a solid tumor diagnosis who experience sleep, pain, or mood problems and have not used cannabis regularly in the last six months. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people, offering participants a chance to contribute to important findings.

Will I have to stop taking my current medications?

You may need to stop taking certain medications to participate in this trial. Specifically, you cannot use anti-epileptic, anti-psychotic medications, or those that interact with Epidiolex. If you're on any of these, you might need to discuss alternatives with your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that CBD (Cannabidiol) may help manage cancer symptoms by reducing pain, improving sleep, and lifting mood. However, it can sometimes affect thinking and memory, which cancer patients should consider.

Full-Spectrum Hemp-Derived CBD (fsCBD) contains both CBD and THC (Delta-9-tetrahydrocannabinol). This combination might increase side effects like trouble thinking clearly. Some people might handle it well, while others may notice these side effects.

Broad-Spectrum Hemp-Derived CBD (bsCBD) contains only CBD without THC, which might lower the risk of thinking problems. However, effects can differ from person to person.

Both types of CBD are still under study to better understand their safety. Since this trial is in Phase 2, earlier tests have shown some safety, but more research is needed to confirm how well it is tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these cannabis-based treatments for palliative care in cancer because they offer a novel approach to managing symptoms. Unlike traditional pain relief methods such as opioids, which can have significant side effects and dependency issues, Full-Spectrum Hemp-Derived CBD (fsCBD) includes both CBD and a small amount of THC, potentially enhancing its pain-relieving effects without high levels of psychoactivity. Broad-Spectrum Hemp-Derived CBD (bsCBD) contains only CBD, which may provide symptom relief without any psychoactive effects at all. These treatments could offer a more natural and potentially safer alternative for managing cancer symptoms, which is why they are gaining attention in the medical community.

What evidence suggests that this trial's treatments could be effective for cancer patients?

Research has shown that cannabis can help cancer patients with pain, sleep, and mood issues. In this trial, participants may receive either full-spectrum hemp-derived CBD (fsCBD), which includes THC, or broad-spectrum hemp-derived CBD (bsCBD), which does not contain THC. Studies have found that full-spectrum hemp-derived CBD might lower pain levels and boost mood. Reviews also support that cannabis can help with pain and improve overall quality of life. Broad-spectrum CBD has also shown promise in alleviating these symptoms. A meta-analysis strongly supports using medical cannabis to improve health outcomes for cancer patients. Overall, these findings suggest that both types of CBD could effectively manage symptoms in cancer care. ^{2 6 7 8 9}

Published Research Related to This Trial

This study will evaluate the efficacy and safety of a 1:1 THC/CBD cannabinoid preparation in managing symptom distress in 150 advanced cancer patients through a randomized, placebo-controlled trial, making it the first of its kind in this area.

Participants will undergo a 2-week titration phase to find an effective dose for symptom relief, followed by a 2-week assessment period, allowing for a comprehensive understanding of the treatment's impact on various symptoms and quality of life.

Oral medicinal cannabinoids to relieve symptom burden in the palliative care of patients with advanced cancer: a double-blind, placebo-controlled, randomised clinical trial of efficacy and safety of 1:1 delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Hardy, J., Haywood, A., Gogna, G., et al.[2021]

Cannabinoids, including THC and CBD, have shown potential in treating cancer-related symptoms such as nausea, pain, and anxiety, with THC and nabilone also aiding in appetite stimulation, while CBD is noted for its anxiolytic and antidepressive properties without psychotropic effects.

Animal studies indicate that high doses of CBD and THC can significantly reduce glioma tumor volumes, with enhanced effects when combined with treatments like X-rays or temozolomide, suggesting cannabinoids may be beneficial in palliative care for brain tumor patients.

Cannabinoids show potential in managing various symptoms in cancer and palliative care patients, including pain, spasticity, and nausea, despite their limited overall efficacy.

They have a favorable safety profile, particularly as they do not depress the respiratory system, making them a useful adjunct to existing treatments, especially in combination with opioids for neuropathic pain management.

Prospects for the Use of Cannabinoids in Oncology and Palliative Care Practice: A Review of the Evidence. Dzierżanowski, T.[2020]

In a study of 108 oncology patients, both THC-dominant and CBD-dominant cannabis treatments showed significant improvements in various cancer-related symptoms, including pain intensity and sleep quality, over a one-month period.

There were no significant safety differences among THC-dominant, CBD-dominant, and mixed cannabis treatments, suggesting that CBD-dominant products can be effective alternatives to THC-dominant products for managing cancer symptoms.

Short-Term Medical Cannabis Treatment Regimens Produced Beneficial Effects among Palliative Cancer Patients. Aviram, J., Lewitus, GM., Vysotski, Y., et al.[2020]

Cannabis and cannabinoid-based medicines have shown favorable outcomes in alleviating chemotherapy-induced nausea and vomiting, as well as managing cancer-related pain, suggesting they can be beneficial in palliative oncology.

While short- and long-term side effects of cannabis use appear manageable and diminish after stopping the drug, further research is necessary to fully understand its efficacy and safety before it can be integrated into standard oncology treatment guidelines.

In a study of 2,431 patients using cannabis for palliative care, a higher ratio of tetrahydrocannabinol (THC) to cannabidiol (CBD) was linked to improved self-reported efficacy in reducing neuropathic pain, insomnia, and depressive symptoms.

The study found that while a higher THC:CBD ratio was beneficial for some symptoms, it did not significantly affect PTSD-related flashbacks or anorexia, and anxiety symptoms showed the best response at a balanced 1:1 THC to CBD ratio.

A qualitative study involving 10 palliative care patients revealed that most participants support the use of cannabinoid-based medicines (CBMs) for symptom relief, distinguishing it from recreational use.

Patients identified several obstacles to CBM prescription, including the need for better information on side effects and a safe medical framework, suggesting that training healthcare professionals could enhance the integration of CBMs in palliative care.

A systematic review of 34 trials found little evidence supporting the effectiveness of cannabinoids as an adjuvant or analgesic for cancer pain, leading to a recommendation against their use for this purpose.

The review highlighted inconsistent evidence regarding the risks and adverse events associated with cannabinoid use in cancer patients, emphasizing the need for careful consideration of potential harms, especially when combined with treatments like checkpoint inhibitors.

A pilot trial involving 21 advanced cancer patients showed that using medicinal cannabis (CBD and THC) for symptom control in palliative care is feasible, with 86% of participants completing the primary outcome measure at day 14.

The study found that the median maximum tolerated doses were 300 mg/day for CBD and 10 mg/day for THC, with 43% of patients experiencing a significant reduction in symptom distress, although drowsiness was the most common adverse event.
