What this trial is about
The goal of this clinical trial is to evaluate the effects of cannabidiol in patients with end-stage metastatic castration-resistant prostate cancer (mCRPC). The primary objective is to determine whether cannabidiol (CBD) treatment can reduce the need for opioids in patients with end-stage mCRPC. Additionally, the study will assess a range of clinical endpoints in patients with end-stage mCRPC, including: 1. The efficacy of CBD treatment in alleviating pain 2. The efficacy of CBD treatment in reducing the need for non-opioid medications and concomitant therapies 3. The impact of CBD treatment on physical activity and quality of life 4. The anti-inflammatory and potential anti-tumor properties of CBD 5. The safety of CBD treatment Patients from Department of Urology, Aalborg University Hospital will be included. Participants will be treated with either CBD (200 mg) or placebo (0 mg) three times daily for nine weeks. At baseline, halfway and end of trial, participants will use an activity tracker and complete questionnaires regarding pain and quality of life and provide blood samples to measure inflammation and tumor activity. Also, they will complete a daily dairy regarding the study drug and intake of pain medication. Adverse events will be assessed by Common Terminology Criteria for Adverse Events.
