A trial looking at cisplatin, gemcitabine and temsirolimus to treat cancer that has spread (ToTem)

Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Cancer type:

Bladder cancer
Kidney cancer
Transitional cell cancer




Phase 1/2

This trial is looking at how well a drug called temsirolimus (Torisel) works with cisplatin and gemcitabine chemotherapy to treat cancer that has spread into surrounding tissue (locally advanced), or to another part of the body. 

Cancer Research UK supports this trial. 

More about this trial

The urinary system filters waste products from the blood and makes urine. Transitional cells (also called the urothelial cells) line the

So you can get transitional cell cancer in the kidney, bladder, ureters or urethra.

Doctors often treat advanced transitional cell cancer with chemotherapy. One combination of chemotherapy drugs they use is cisplatin and gemcitabine.

Temsirolimus is a type of biological therapy. It is a cancer growth blocker. It stops signals that cancer cells use to divide and grow.

The aims of this trial are to find out

  • How well the combination of temsirolimus, cisplatin and gemcitabine works in treating advanced transitional cell cancer
  • How safe the combination is
  • What the side effects of this drug combination are
  • What is the best dose of this combination to give

Who can enter

There are 2 parts to this trial.

You may be able to enter the 1st part of the trial if you have a solid tumour Open a glossary item that has spread into the surrounding tissue (locally advanced) and can't be cured or has spread to another part of your body. And there is no standard treatment Open a glossary item or gemcitabine and cisplatin is an accepted standard treatment (your doctor can tell you).

You may be able to enter the 2nd part of this trial if you

  • Have transitional cell cancer of the bladder, centre of the kidney (renal pelvis) or tubes that drain urine from the kidneys to the bladder (ureters) or tube that drains urine from the bladder and out the body (urethra)
  • Have transitional cell cancer that has spread to surrounding tissue or to another part of your body
  • Have an area of cancer spread can be seen or measured on a scan
  • Have satisfactory blood test results
  • Are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
  • Are willing to use reliable contraception
  • Are at least 16 years old

You cannot enter this trial if

  • You have leukaemia Open a glossary item, lymphoma Open a glossary item or myeloma Open a glossary item
  • You are able to have surgery or radiotherapy with the aim to cure your cancer
  • Your cancer has spread to your brain or spinal cord
  • You have had a treatment that reaches your whole body (systemic treatment Open a glossary item) for your transitional cell cancer. You may be able to join part 1 of the trial, if you have finished your chemotherapy at least 1 month ago. You may be able to join part 2 of the trial, if you have had no more than 4 cycles of chemotherapy and finished your treatment at least 6 months ago
  • You have had radiotherapy in the past month
  • You had radiotherapy to more than a third of your bones that make blood cells – you can check this with your doctor
  • You have had an experimental drug as part of a clinical trial in the past month
  • You are having certain types of medication that thin the blood
  • You are taking medications that affect the CYP3A4 enzyme
  • You have had a heart attack in the past 6 months, or any other serious heart problem
  • You have certain infections
  • You have HIV, hepatitis B or hepatitis C
  • You are pregnant or breastfeeding

Trial design

This is trial is in 2 stages. The first stage is a phase 1 trial. It will recruit 42 people. In this stage the researchers want to find out the best dose of temsirolimus to give with cisplatin and gemcitabine.

The first patients taking part will have the lowest dose of temsirolimus. 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.

The second stage is a phase 2 trial. It will recruit another 63 people.

Everyone will have temsirolimus, cisplatin and gemcitabine. You have them as an injection into a vein every 3 weeks. Each 3 week period is called a cycle of treatment. You can have up to 6 cycles.

If you agree to take part in this study, the researchers will ask for some extra blood samples and a piece of tissue taken from when you had surgery or a biopsy Open a glossary item. They will use these samples to find out more about how the combination of temsirolimus, cisplatin and gemcitabine work in your body. If you don’t want to give tissue samples for this study, you don’t have to. You can still take part in the trial.

Hospital visits

You see the doctor and have some tests before taking part in this trial. These tests include

  • A physical examination
  • Blood tests
  • Heart trace (ECG Open a glossary item)
  • CT scan

When you have treatment your doctor may suggest you stay in hospital for 1 or 2 nights.

During treatment you see the doctor each week for blood tests. You have a CT scan before your 4th cycle of treatment, at the end of treatment, then after 6 months and 12 months.

After treatment your doctor will talk to you about how often they want to see you.
