About this trial
Despite the proliferation of cannabis and cannabinoid products in recent years, little research has been done to determine the impact of these products on womens health conditions, including endometriosis. This study is designed to assess the impact of a custom-formulated, hemp-derived, full-spectrum, high-CBD product vs. placebo on clinical symptoms and biomarkers over the course of 12 weeks of treatment in patients with endometriosis. This project will provide information that does not currently exist on the potential efficacy of a cannabinoid-based sublingual product for endometriosis.

Treatment groups
Trial outcomes
Primary outcomes
Visual Analog Scale (VAS)
The VAS is a commonly used pain scale where patients draw a line to indicate their pain level on a 100 millimeter long line anchored by two verbal descriptors for symptom extremes (e.g. "no pain" to "worst imaginable pain"). The VAS will be used to describe different types of endometriosis-related pain (dysmenorrhea (pain during menstruation), dyspareunia (pain during or after intercourse), and non-menstrual chronic pelvic pain). Lower scores indicate less pain.
Secondary outcomes
Endometriosis Health Profile (EHP-30)
The EHP-30 is a well-validated self-report scale with 30 core items and 23 additional questions related to specific modules and areas of life often impacted by endometriosis symptoms. Lower scores indicate fewer symptoms.
VAS-IBS
The VAS-IBS queries bowel-related concerns. While initially developed for IBS patients, it is commonly used to assess gastrointestinal symptoms in endometriosis patients. Lower scores indicate fewer bowel symptoms.
Beck Anxiety Inventory (BAI)
The BAI is a 21 item-self-report measure that can be used to screen for anxiety. Each item on the BAI is rated on a scale of 0 to 3, and is descriptive of subjective, somatic, or panic-related symptoms of anxiety. Lower scores indicate fewer symptoms of anxiety.
Beck Depression Inventory (BDI)
The BDI is a 21 item-self-report measure that can be used to assess the severity of depression. Each item on the BDI relates to a symptom of depression and is rated by the subject using a 0-3 scale. Lower scores indicate fewer depressive symptoms.
