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


The proposed investigation will be the first of its kind to conduct a clinical trial of an industrial hemp-derived product (study product) in patients with glioblastoma. Despite the recent interest in medicinal cannabis (MC) and cannabinoid-based products, the availability of hemp-derived products in all 50 states, and anecdotal evidence suggesting that hemp-derived products may have a profound anxiolytic effect, no studies have conducted a clinical trial of a hemp-derived product in these patients despite their reported levels of anxiety.

This is a randomized, double-blind, placebo-controlled study designed to examine the impact of a custom-formulated, high CBD product on measures of anxiety, quality of life, and tumor progression and imaging stability in newly-diagnosed glioblastoma patients. The custom formulation contains approximately 250 mg/ml of CBD and 1.8 mg/ml THC, along with several other cannabinoids.

  4. Fluent in English
  5. Scores a minimum of 16 on the Beck Anxiety Inventory (BAI) OR a minimum of 11 on the Overall Anxiety Severity and Impairment Scale (OASIS) at the screening visit
