"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A trial looking at pembrolizumab for people with urothelial (urinary tract) cancer
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at pembrolizumab for cancer of the urinary tract that can’t be removed with surgery, has come back after treatment, or has spread elsewhere in the body.
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 (
The lining of the urinary tract is called the
More about this trial
Doctors often treat urothelial cancer with surgery. But sometimes the cancer can’t be removed from surgery, or it can come back after treatment and it can spread to other parts of the body.
In this situation doctors often use a chemotherapy drug called cisplatin. Some people cannot have cisplatin and so doctors want to see if another type of drug called pembrolizumab will work. Pembrolizumab is a type of biological therapy called a monoclonal antibody. It helps the immune system to kill cancer cells.
The aims of this trial are to
- See if pembrolizumab works as a treatment for urothelial cancer
- Find out more about the side effects of pembrolizumab
Who can enter
You may be able to join this trial if all of the following apply. You
- Have urothelial cancer of either the renal pelvis, ureter, bladder or urethra that cannot be removed with surgery, or that has come back after treatment, or spread elsewhere in the body
- Have cancer that can be measured on a scan
- Can have a sample of your cancer (a
- Are not able to have cisplatin chemotherapy for some reason (the trial team can advise you about this)
- Have satisfactory blood test results

- At least 18 years old
You cannot join this trial if any of these apply. You
- Have had platinum based chemotherapy for advanced urothelial cancer. If you had chemotherapy either before or after surgery to try to stop your cancer coming back, you may be able to take part if your cancer didn’t come back for at least a year
- Are able to have a treatment just to the area where your cancer is that could cure your cancer for example surgery or radiotherapy
- Are already taking part in a clinical trial or research study or have had an experimental treatment in the last 4 weeks
- Have had a monoclonal antibody in the last 4 weeks
- Have not recovered from any side effects due to having had a monoclonal antibody in the past
- Have had chemotherapy, other cancer drugs or radiotherapy in the last 2 weeks or you have not recovered from earlier treatment
- Have had previous treatment with any anti-PD1 or anti- PD2 drugs (your doctors can advise you about this)
- Have had a live vaccine in the last 30 days
- Have another type of cancer except for non melanoma skin cancer that has been successfully treated carcinoma in situ of the cervix or early stage prostate cancer (your doctors can advise you about this)
- Have cancer that has spread to your brain or spinal cord and is causing symptoms (you can take part if cancer spread to your brain was treated at least 4 weeks ago and is not causing symptoms)
- Have inflammation of the covering of the brain (carcinomatous meningitis) caused by your cancer
- Have problems with your
immune systemmaking you more likely to get infections
- Have an
autoimmune diseaseand have had drugs that suppress your immune system in the last 2 years. Some other types of drugs are allowed and your doctor can advise you
- Have a lung condition called interstitial lung disease
- Have an infection which needs treatment
- Have HIV, hepatitis B or hepatitis C
- Have any other medical condition or mental health problem that the trial team think could prevent you taking part
- Are pregnant or breastfeeding
This is a phase 2 trial. The doctors need around 350 people to take part. Everybody taking part has pembrolizumab.
You have pembrolizumab through a drip into the vein once every 3 weeks. Each 3 week period is called a cycle of treatment. The doctors will tell you how many cycles of treatment you will have, but as long as the treatment is working you can have the drug for up to 2 years.
If you agree to take part, the trial team will ask for a tissue sample (
The trial team will ask you to fill out some questionnaires when you go for treatment. The questionnaires will ask about side effects and how you’ve been feeling. They are called quality of life studies.
You will see the doctors and have some tests before you start treatment. The tests may include
You go to the hospital once every 3 weeks for treatment. At these visits you will have a physical examination and blood and urine tests. 9 weeks after you start treatment you have a CT scan. You will also have MRI scan and you may have a bone scan. This is to see how well the treatment is working. After this you will have these scans very 6 weeks for the first year. Then you will have them every 3 months until your cancer gets worse. Your doctor may want you to have the scans more often and they will discuss this with you.
When you finish treatment you see the trial team about 1 month later. After that, you see them every 6 weeks for the first year and then every 3 months until your cancer grows or you start another treatment for your cancer.
If your cancer gets worse or you start a new cancer treatment the trial team will telephone you every 3 months to see how you are.
Pembrolizumab is a new drug so not all the side effects may be known yet. The most common side effects of pembrolizumab are
- Tiredness and lacking in energy (fatigue)
- Itchy skin
- Needing to open your bowels more often
- Painful joints
- Feeling sick
We have information about the side effects of pembrolizumab.
Your doctor will talk to you about the possible side effects before you agree to take part in this trial.
