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 more treatment after chemotherapy for advanced urinary tract cancer (urothelial cancer) (ATLANTIS)
This trial is testing different treatments for different subtypes of urinary tract cancer. It is for people whose cancer has grown into surrounding tissues or spread elsewhere in the body (advanced cancer).
The urinary tract includes the:
- centre of the kidney (renal pelvis)
- tube that takes urine from the kidney to the bladder (ureter)
- tube that drains urine from the bladder and out of the body (urethra)
Cancer Research UK supports this trial.
More about this trial
Chemotherapy is one of the usual treatments for advanced urothelial cancer. After chemotherapy, you have regular monitoring. This means you don’t have treatment straight away. Your doctor keeps a close eye on you to check for any signs that the cancer is growing. If it does, then you and your doctor decide which treatment is best for you.
Researchers are looking at ways to delay the cancer growing again after chemotherapy. We know from research in other cancers that having more treatment (sometimes called maintenance therapy) can increase the time it takes for the cancer to come back. Researchers want to see if this also happens in people with advanced urinary tract cancer.
But not all urinary tract cancers are the same and some new cancer drugs may help people with one type of urinary tract cancer more than another.
To work out the subtype of urinary tract cancer you have, the researchers will test a sample of your cancer (
The trial team hope to test a number of different treatments. But for now, there is only one part of the trial that is open. This part is called ATLANTIS-1 and it is looking at a drug called cabozantinib. This is a type of targeted cancer drug (
Cabozantinib works in 2 different ways. It blocks particular proteins on cancer cells. These proteins encourage the cancer to grow. It also stops the cancer cells growing blood vessels, which the cells need to be able to grow. Researchers hope that cabozantinib might delay the cancer growing for a time.
The overall aims of this trial are to find out:
- if having additional treatment can increase the time before these cancers come back
- if having more treatment can help people live longer
- what the side effects are

non melanoma skin cancerthat was successfully treated or early prostate cancer and you don’t need hormone treatment
- Your kidneys, liver or other organs in the body aren’t working properly
- You have had any other treatment as part of a clinical trial in the last 28 days
- You have any other serious medical condition or mental health problem that the trial team think could affect you taking part
- You are pregnant or breastfeeding
As well as the above
You cannot join ATLANTIS-1, if any of the following apply. You
- Have cancer that has spread to your brain or tissues covering your brain unless this has been treated with surgery or radiotherapy, has not got worse in the 4 weeks before starting the trial, and you are no longer taking steroids
- Have cancer that has grown into a major vein in the lungs
- Have had a type of drug called a tyrosine kinase inhibitor such as axitinib or pazopanib
- Have had treatment with cancer drugs that affect certain proteins such as MET crizotinib and VEGF such as bevacizumab, sorafenib and vandetanib
- Have had any targeted cancer drug in the 4 weeks before joining the trial
- Have had chemotherapy in the last 3 weeks (6 weeks if you had chemotherapy drugs called
nitrosoureasor mitomycin C)

This phase 2 trial is based in the UK. The part of the trial called ATLANTIS-1 is open. The researchers need 140 people to join.
The doctors test a sample of your cancer taken when you had a previous biopsy or surgery. They will try to classify your cancer as a particular subtype.
If you don’t have a specific biomarker being looked at (you are biomarker negative), you might be suitable to join this part of the trial.
It is a randomised trial. You are put into 1 of 2 groups to have 1 of the following:
- dummy drug (
Neither you nor your doctor will be able to decide which group you are in. And neither of you will you know which group you are in. This is called a double blind trial.
Cabozantinib and the dummy drug are tablets. They look the same and come in the same packaging. You take them once a day, everyday. The trial team will give you a fresh supply of tablets every 4 weeks.
You have treatment as long as it is working and the side effects aren’t too bad. You stop treatment if your cancer gets worse. Your doctor will talk to you about other treatment options.
The trial team will ask to take some extra blood samples as part of this trial. This is to look for
Biomarkers help to predict who is most likely to benefit from this treatment and also help us to better understand advanced urinary tract cancers.
You don’t have to give these samples if you don’t want to. You can still take part in the trial.
You see a doctor and have some tests before you can take part. These include:
You see the trial team once a month for a check up and some blood tests. You have a CT scan or MRI scan every 3 months.
When you finish treatment you see the trial team:
- a month later
- every 3 months
The most common side effects of cabozantinib include:
- diarrhoea or constipation
- tiredness (fatigue)
- feeling or being sick
- loss of appetite
- redness of the skin on palms of hands and soles of feet (hand foot syndrome)
- high blood pressure
- taste changes
- changes to your voice
- muscle weakness
You should avoid grapefruit and Seville oranges as they might increase the levels of cabozantinib in the body.
The trial team will talk to you about all the possible side effects before you agree to join.
