Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A study looking at dexanabinol for advanced cancer
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This study is looking at dexanabinol for solid tumours. A
Doctors use treatments such as surgery, radiotherapy and chemotherapy to treat cancer. But sometimes cancers continue to grow or spread to another part of the body despite having all the
Dexanabinol is a man made (synthetic) form of a chemical similar to that found in the cannabis plant. Dexanabinol does not have any cannabis like effects, but we know from laboratory research that it may affect cancer cells. This is the first time it has been tested in people with cancer. The aims of the study are to
- Find the highest safe dose of dexanabinol
- See what affect it has on your cancer
- Learn more about the side effects and what happens to the drug in your body
Who can enter
You may be able to enter this trial if you
- Have a
solid tumourand there are no standard treatments available for you
- Have cancer that can be measured on a scan or by looking at substances called tumour markers
- Are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- Have satisfactory blood test results
- Are at least 18 years old
- Are willing to use reliable contraception during the trial and for a month afterwards if there is any chance you or your partner could become pregnant
If you’ve had treatment for cancer that has spread to your brain, you may be able to take part as long as this has not got any worse for at least 4 weeks before joining the trial.
You cannot enter this trial if you
- Have not recovered from the side effects of other cancer treatment (apart from hair loss) unless they are very mild
- Have had radiotherapy in the last 4 weeks unless it was radiotherapy to control symptoms
- Have had chemotherapy in the last 4 weeks (6 weeks if you had mitomycin C or drugs called
- Have had major surgery in the last 6 weeks
- Have had another experimental drug in the last 4 weeks
- Have hepatitis B, hepatitis C or another disease affecting your liver (apart from cancer)
- Have certain heart problems
- Have had a bad infection in the last 4 weeks or have any other medical condition that the study team think could affect you taking part
- Are known to be HIV positive
- Are pregnant or breastfeeding
This phase 1 trial will recruit about 45 people in the UK. Everybody taking part has dexanabinol. The first few patients taking part will have a low dose of dexanabinol. If they don’t have any serious side effects, the next patients will have a higher dose. And so on, until they find the best dose to give. This is called a dose escalation study.
You have dexanabinol through a drip into a vein once a week. It takes about 3 hours each time.
Each 3 week period is called a cycle of treatment. You have up to 6 cycles of treatment. As long as you don’t have bad side effects and dexanabinol seems to be helping, the study doctor may talk to you about taking it for longer.
The study team will ask your permission to get a sample of your tumour that was removed in the past when you had surgery or a
They will use these samples to look at how dexanabinol affects cancer cells. But this is optional. If you don’t want to give these samples for research you don’t have to.
You see the study team and have some tests before you start treatment. The tests include
You go to hospital at least once a week during treatment. Each visit will last a few hours and in the 1st cycle of treatment, you may need to stay in hospital overnight on 2 occasions. This is because you have a number of blood tests at different times after having dexanabinol. Researchers will use these blood samples to learn more about what happens to the drug in your body (
You have regular blood tests throughout your treatment. You have an ECG every 3 weeks and a CT or MRI scan every 6 weeks.
After you finish treatment, you go back to see the study team about a month later. You have a physical examination and more blood tests. You may have another scan.
As this is the first time dexanabinol is being tested in people with cancer, there may be side effects we don’t know about yet. It has been looked at in trials with healthy volunteers, people having heart surgery and people with brain injuries. In these trials, the most common side effects were
- Redness, rash or flushing in the face, neck and chest
- An abnormal heart rhythm called atrial fibrillation
- An increase in the amount of sugar in the blood
- A decrease in the amount of iron in the blood
- An increased number of white blood cells
- High temperature (fever)
- Headache (in people who had brain injuries)
- Lung infection
The study doctors will talk to you about other possible side effects.
How to join a clinical trial
Please note: In order to join a trial you will need to discuss it with your doctor, unless otherwise specified.
