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 trial of CVA21 to treat cancer (STORM)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This is trial looking at the CVA21 virus to treat cancer. The trial is open to people with one of the following cancers
The trial is for people with cancer that has spread to the surrounding tissue or to another part of the body (advanced cancer).
More about this trial
Unfortunately there are no treatments doctors can give with the aim to cure people with these types of advanced cancer. But they are always looking for treatments that can increase the length of time people live or to delay the cancer coming back after treatment.
CVA21 (also called CAVATAK) is a naturally occurring
The aims of this trial are to find
- The highest safe dose of CVA21
- What the side effects are
- What happens to CVA21 in the body
- How well CVA21 works
Who can enter
You may be able to join this trial if you have one of the following cancers that has spread to another part of your body
- Non small cell lung cancer
- Bladder cancer
- Melanoma skin cancer. If your melanoma has spread to nearby lymph nodes or is ulcerated (number stage 3c) you may also be able to join
And you must also
- Have an area of cancer that the trial team can take a small sample of tissue (
biopsy) or a sample of fluid and cells ( fine needle aspiration) from (the trial team can advise you about this)
- Be well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- Be at least 18 years old
You cannot join the trial if any of the following apply. You
- Have a certain level of CVA21
antibodiesin your blood (the trial team will test for this)
- Are able to have the
standard treatmentfor your cancer
- Have had
chemotherapyor radiotherapyin the past 28 days
- Have had
immunotherapyor hormone therapyin the past 28 days
- Still have any side effects from previous treatment unless they are mild
- Are taking medications that affect your
immune system(unless it is a low dose of steroids)
- Have another type of cancer
- Have certain heart problems (the trial team can advise you about this)
- Have an infection that isn’t controlled by medication
- Have HIV or any other disease that can affect your immune system
- Have hepatitis B or hepatitis C
- Have another medical or mental health problem that the trial team thinks could affect you taking part in the trial
- Are pregnant or breastfeeding
This is a phase 1 trial. The researchers need 9 to 12 people to join.
The first few people who took part had the lowest dose of CVA21. As they don’t have any serious side effects, the next few people will have a higher dose. And so on, until they find the best dose. This is called a dose escalation study.
You have CVA21 as a drip into a vein. It takes 30 minutes. To start you have 3 treatments on different days in the first week. Then you have it once every 3 weeks. Each 3 week period is called a cycle of treatment. You can have up to 8 cycles of treatment.
Because the virus in CVA21 is similar to the common cold after each treatment it may be present in your lungs and
As part of the study the researchers will ask your doctor to take a small sample of cancer tissue (
You see the doctor to have some tests before taking part in the trial. These tests include
During the 1st week of treatment you see the doctor 4 times for blood tests and a physical examination. You also have a heart trace before your first treatment.
You then see the doctor every 3 weeks before treatment for a physical examination, heart trace and blood tests.
You have a CT scan or MRI scan before your 3rd, 5th and 7th cycle of treatment.
After completing treatment you see the doctor for the same tests you had at the start. Your doctor will also tell you how often and for how long they want to see you.
CVA21 is a new treatment and there may be side effects we don’t know about yet. The side effects reported so far include
- Feeling sick
- Muscle pain
- Tiredness (fatigue)
- Feeling weak and sore
- A drop in blood cells causing an increased risk of bruising and bleeding
- High temperature (fever)
- Back and neck pain
- Tummy (abdominal) pain
- Joint and bone pain
- Flu like symptoms
- Hand cramps
- Reddening of the skin
- Voice changes
- Tenderness in the groin
- Symptoms of a head cold
- Pain at the injection site
The trial doctor will talk to you about the possible side effects before you agree to take part in the trial.
