What this trial studies

This clinical trial aims to evaluate the effectiveness of the cannabis extract Avextra 10/10 in reducing symptom burden and enhancing the well-being of patients undergoing palliative care for cancer. A total of 170 participants will be randomly assigned to receive either the cannabis extract or a placebo over a period of 12±2 days. The primary outcome will be measured using the Edmonton Symptom Assessment System total symptom distress score, with additional assessments of quality of life and other parameters at multiple time points. The study seeks to contribute to evidence-based medicine in palliative care, particularly for elderly and severely ill patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 25 and older who are receiving palliative oncological therapy and have a significant symptom burden.

Not a fit: Patients with severe nausea or vomiting, those who have used cannabis recently, or individuals with certain contraindications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option to significantly improve the quality of life for patients with advanced cancer.

How similar studies have performed: Other studies have shown promising results with cannabinoid therapies in palliative care, suggesting potential for success in this approach.
