About this study
Official title: Improvement of Quality of Life by Cannabinoids in Oncologic Patients (BEfindLichkeitsverbesserung Unter CANnabinoid-ExtrakTen Bei Onkologischen Patienten)
The goal is to explore whether the application of cannabis extract Avextra 10/10 solution is suitable to contribute to an improvement in the symptom burden and well-being of oncological palliative care patients. The primary objective of the study is to demonstrate the improvement in global symptom burden in the intervention arm compared to the placebo control group over a period of 12±2 days, as measured by a percentage change in the value of the Edmonton Symptom Assessment System total symptom distress score (ESAS TSDS) at baseline and after 12±2 days.
Read the detailed description
170 oncological patients in palliative treatment will be randomized 1:1 to an THC:CBD-interventional arm and an placebo-arm. At the timepoints baseline, 12±2 days, 18±3 days, four weeks and eight weeks, the global burden of symptoms (ESAS TSDS), quality of life (EORTC QLQ C15 PAL) and other parameter will be measured and the intraindividual difference in comparison with the baseline will be compared between the groups. This study is intended to provide a significant contribution to Evidence-based medicine (EbM) of CAM in palliative medicine as well as for elderly and severely ill subjects (resp.) in general.
The following gain of knowledge is expected:
- substancial and reliable effects of CAM in elderly subjects being in a multimorbid and psychologically very stressful situation of illness and life (resp.).
- substancial and reliable effects of CAM in aduld subjects being in a oncologically and palliative situation of illness and life (resp.).
- compatibility of a CAM-therapy in multimorbid patients with polypharmacotherapy.
- importance of CAM for the very frequent psychovegetative disturbance and comorbidities of many illnesses like sleepnesness, loss of appetite, nausea, fear and affective disturbance.
- possible reduction of costs and improved economics through CAM

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Cannabisextrakt Avextra 10/10 Lösung in people with Medical Oncology and Palliative Care, run by University Hospital Schleswig-Holstein at 3 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Given the current recruitment rate and the changes in the treatment landscape, there is no reasonable expectation of achieving the planned sample size.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ESAS-TSDS score (time frame: 12 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
