A Clinical Trial of a Hemp-Derived, High Cannabidiol Product for Anxiety in Glioblastoma Patients

Study Purpose

Glioblastoma (GBM) is the most common malignant brain tumor among adults. As the diagnosis is generally considered terminal, patients with GBM often suffer from anxiety and other comorbid conditions, including depression, pain, and sleep disturbance, all of which significantly impact their quality of life. Previous studies have demonstrated the potential of cannabinoids, particularly cannabidiol (CBD), to improve the aforementioned symptoms without conferring significant risks or side effects. Further, recent in-vitro and in-vivo work suggests potential cytotoxic and anti-tumor effects of CBD and other cannabinoids. This study includes a double-blind, placebo-controlled, 8-week randomized clinical trial assessing the impact of a custom formulated, full-spectrum, hemp-derived ultra-high CBD product on measures of anxiety, pain, and quality of life in newly-diagnosed GBM patients undergoing standard of care (SOC) treatment; the impact of this product vs.#46; placebo on tumor progression will also be assessed. The proposed clinical trial will provide important information that does not currently exist regarding the potential efficacy of a novel full-spectrum, ultra-high CBD product to address clinical symptoms in patients with GBM.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT05753007
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
