A trial looking at hormone therapy with other treatments for prostate cancer (STAMPEDE)

This trial is comparing hormone therapy alone with a combination of hormone therapy and either zoledronic acid, docetaxel (or both), celecoxib, abiraterone or radiotherapy for prostate cancer. This trial is supported by Cancer Research UK.

Doctors often use hormone therapy to treat prostate cancer that has spread outside the prostate gland. It can work very well, but the cancer often starts to grow again at some stage. Doctors think that having other treatments at the same time as hormone therapy may work better. 

In this trial, everybody will have hormone therapy as they usually would. But some will have other treatments as well. The treatments are

The aim of this trial is to see which treatment is best for prostate cancer that has spread outside of the prostate gland.

Recruitment

Start 19/09/2005
End 01/11/2015

Phase

Phase 2/3

Who can enter

You can enter this trial if 

  • You have recently been diagnosed with prostate cancer that has spread outside the prostate gland into your lymph nodes or to another part of your body

OR

  • You have recently been diagnosed with prostate cancer that has not spread outside the gland if at least 2 of the following apply to you - your prostate cancer has broken through the capsule covering the gland, you have a PSA level of 40 or above, or you have a Gleason score of 8 or above

OR

  • You have prostate cancer that has started to grow again following surgery or radiotherapy and has now either spread into your lymph nodes or to another part of your body, or you have a PSA level of 20 or more, or a PSA level above 4 if it has doubled in less than 6 months

As well as that, you must

You cannot enter this trial if you

  • Have prostate cancer that has spread to the brain
  • Have had chemotherapy or any other treatment that reaches the whole body (systemic treatment) for prostate cancer
  • Have any other cancer that the doctors think may affect the treatment or the trial results
  • Have numbness or tingling in your hands or feet (peripheral neuropathy) unless it is very mild
  • Have had surgery in the last 4 weeks
  • Have a serious heart condition, high blood pressure that cannot be controlled with medication or have had a heart attack or stroke in the past
  • Have a peptic ulcer, bleeding into your gut or inflammatory bowel disease
  • Have already had zoledronic acid, unless it was just for a short time to treat a raised level of calcium in your blood (hypercalcaemia)
  • Have already had abiraterone
  • Take other medication that can affect an enzyme called CYP3A4
  • Are likely to need major dental work in the next 2 years

Trial design

The trial will recruit about 5,000 men all together. It is a randomised trial. The men taking part are put into treatment groups by a computer. Neither you nor your doctors will be able to decide which group you are in.

  • Group A have just hormone therapy or an orchidectomy
  • Group B have hormone therapy or an orchidectomy, plus zoledronic acid (zoledronate or Zometa)
  • Group C have hormone therapy or an orchidectomy, plus docetaxel (Taxotere)
  • Group D have hormone therapy or an orchidectomy, plus celecoxib
  • Group E have hormone therapy or an orchidectomy, plus zoledronic acid and docetaxel
  • Group F have hormone therapy or an orchidectomy, plus zoledronic acid and celecoxib
  • Group G have hormone therapy or an orchidectomy, plus abiraterone tablets
  • Group H have hormone therapy or an orchidectomy, plus radiotherapy to the prostate

Please note - By January 2014, there were enough men in groups B, C, D, E, F and G. So men joining the trial after that were not put into either of those 6 groups. In January 2013, group H opened to recruitment for men whose cancer has spread outside the prostate. So men joining the trial are put into group A or H.

All the men taking part will have hormonal treatment. This could be hormone injections, tablets or an operation to remove both testicles (an orchidectomy). The hormone testosterone is made by the testicles, so if they are removed, the level of testosterone falls dramatically.  Any other treatment you have will depend on which treatment group you are in.

If you are in group H, you have radiotherapy either once a week for 6 weeks, or 5 times a week for 4 weeks. If you have radiotherapy 5 times a week for 4 weeks, each dose is lower than if you have it weekly, but the total dose is a bit higher.

The trial team will ask you to fill out a number of questionnaires during the trial. These ask about any side effects you have had and about how you have been feeling. This is called a quality of life study. They will also ask for an extra blood sample and a sample of tissue taken when your cancer was diagnosed. They will look at the DNA and proteins in your samples to learn more about the causes of prostate cancer and how it responds to different treatments. If you don’t want to give samples for this study, you don’t have to. You can still take part in the trial.

Hospital visits

You will see the doctors and have some tests before you can take part in this trial. The tests include

How often you go to the hospital for treatment will depend on which group you are in. But everybody taking part will see the trial team

  • Every 6 weeks for the first 6 months
  • Every 3 months up to 2 years
  • Then every 6 months up to 5 years
  • Once a year after that
