A Clinical Trial of a Hemp-Derived, High Cannabidiol Product for Anxiety in Glioblastoma Patients
- Registration Number
- NCT05753007
- Lead Sponsor
- Mclean Hospital
- Brief Summary
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. 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.

- Written informed consent obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study.
- Fluent in English.
- Endorses at least moderate levels of anxiety (on the BAI or OASIS) at the screening visit
- Stable medication/psychotherapy regimens for at least 1 month prior to starting the study (excluding new glioblastoma treatment-related medications or radiation).
- Karnofsky Performance Scale (KPS) of 60 or higher.

Group Intervention Description Placebo Placebo Placebo solution administered for 8 weeks along with standard of care treatment Cannabidiol (CBD) Solution Plus Standard of Care (SOC) Cannabidiol (CBD) Full-spectrum, hemp-derived, ultra-high CBD solution administered for 8 weeks along with standard of care treatment
- Primary Outcome Measures
Name Time Method Change from Baseline in Self-Reported Anxiety as Assessed by the Beck Anxiety Inventory (BAI) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The BAI is a 21-item self-report measure used to rate subjective, somatic, and panic-related symptoms of anxiety on a scale of 0 to 3 (higher scores indicating more anxiety).
Change from Baseline in Anxiety Assessed by the Overall Anxiety Severity and Impairment Scale (OASIS) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The OASIS is a brief 5-item measure used to evaluate the functional impairment cause by anxiety; the frequency and intensity of anxiety, as well as the degree of avoidance and interference with work and social function are rated on a scale of 0 to 4 (higher scores indicating more anxiety).
- Secondary Outcome Measures
Name Time Method Change from Baseline in Sleep Quality Assessed by the Pittsburgh Sleep Quality Index (PSQI) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The PSQI contains 19 self-rated questions that assess sleep quality and disturbance over the previous 1-month period. The 19 items yield seven component scores such as sleep latency, sleep duration, and daytime dysfunction, which are then summed to generate a global score (higher scores indicating decreased sleep quality).
Patient's Global Impression of Change (PGIC) at Follow-Up 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The PGIC is a single-question, 7-point scale depicting a patient's rating of overall improvement from "very much worse" to "very much improved".
Change from Baseline in Pain Assessed by the Brief Pain Inventory (BPI) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The BPI contains 9 questions that assess the severity of pain, how much relief is provided by treatment, and the functional impact of the pain within the last 24 hours. Lower scores are better.
Change from Baseline in Pain Assessed by the Pain Distress Scale (PDS) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The PDS is an 11-point scale one where patients rate their pain by level of distress the pain causes on a scale of 0 to 10. Lower scores are better.
Change from Baseline in Pain Assessed by the Pain Disability Index (PDI) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks On the PDI, the patient rates how their pain affects 7 different areas of their life on a scale of the level of disability that their pain causes, from "no disability" to "worst disability". Lower scores are better.
Change from Baseline in Pain Assessed by a Visual Analog Scale (VAS) 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The VAS is a 100mm line where patients draw a vertical line to indicate their pain level from 0-100. Lower scores are better.
Change from Baseline in Quality of Life Assessed by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-BN20 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The EORTC QLQ-BN20 module contains 20 additional questions specifically for brain tumor patients. Lower scores indicate better quality of life and fewer symptoms.
Change from Baseline in Quality of Life Assessed by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks The EORTC QLQ-C30 contains 30 questions assessing a cancer patient's quality of life. Lower scores indicate better quality of life and fewer symptoms.
