  Purpose

Prostate cancers need the male hormone testosterone to grow. Hormone treatments work by stopping testosterone from reaching prostate cancer cells. There are different types of hormone treatments but the most common are injections or implants that work by stopping the testicles making testosterone. Some men will have an operation to remove a part or all of the testicles instead. This type of treatment is called hormone treatment or androgen deprivation therapy (ADT) and it is part of the current standard approach to the treatment of locally advanced or metastatic prostate cancer. In addition, radiotherapy to the prostate and or docetaxel chemotherapy may be recommended as part of the current standard-of-care.

The overall aim of this trial, which is called STAMPEDE, is to assess novel approaches for the treatment of men with prostate cancer who are starting long-term ADT for the first time, termed hormone-naïve prostate cancer. This trial aims to see if we can improve the way in which prostate cancer is currently managed, either by adding new treatments to the standard approach or by modifying the type of hormone therapy aiming to improve quality-of-life by reducing the side effects of treatment. Each new treatment approach is compared against a control arm receiving the current standard treatments. We aim to identify treatment strategies that enable men to live longer, or as long but with an improved quality-of-life, as well as offering value for money for the health service.

Since opening to accrual in Oct-2005, the trial has tested many ways of treating prostate cancer and some results are now already known. More than 10,000 men will join the trial with answers becoming available throughout the trial. New patients joining the trial from Protocol version 16.0 onwards (activated in June 2017) may be eligible to join one of two treatment comparisons, metformin (treatment group K; the "metformin comparison") and transdermal oestradiol (treatment group L; the "transdermal oestradiol comparison"). A computer program will be used to allocate which treatment each participant receives, using a chance process.

Summary of the research arms in STAMPEDE trial platform Summary of research treatment groups currently open to recruitment (June 2017)

  1. Metformin (Arm K): This anti-diabetic medication is proposed to have both anti-cancer effects and may help prevent the adverse metabolic effects of long-term ADT. STAMPEDE will investigate whether adding metformin to the current standard-of-care for non-diabetic men can improve all-cause survival.
  2. Transdermal oestradiol (Arm L): This is an alternative form of hormone treatment which has been shown to suppress testosterone as effectively as standard ADT and avoid some of the side-effects. It may also help to avoid the adverse metabolic effects and fatigue and therefore improve overall quality of life compared with standard forms of ADT. STAMPEDE will investigate whether transdermal oestradiol can treat the cancer as well as current standard forms of ADT.
  3. Control group (Arm A): Patients allocated to this group receive the current standard-of-care ADT +/- RT +/- docetaxel.

Detailed Description:

STAMPEDE (also known as MRC PR08) is a multi-arm multi-stage (MAMS) randomised controlled trial recruiting in the UK and Switzerland. It aims to evaluate multiple therapeutic strategies in the management of high-risk locally advanced and metastatic hormone-naïve prostate cancer. Each novel treatment strategy is compared against a single, contemporaneous control arm. When the trial originally opened in 2005 there were 6 research arms enabling 5 randomised comparisons. Each comparison is evaluated in stages with pre-planned interim analyses after which recruitment may be halted should the experimental treatment fail to reach a "hurdle" of activity. Patient data from all arms and all stages are, however, included in the final analyses of the primary outcome measure, even if the investigational arm did not proceed to the final stage.

Providing sufficient activity is demonstrated, recruitment continues to the final stage and then an assessment of efficacy is determined based on the primary outcome of overall survival. Patient data from all arms and all stages are included in the final analyses of the primary outcome measure, even if the investigational arm did not proceed to the final stage.

The original comparisons which have all now been reported, evaluated a bisphosphonate (zoledronic acid), a cytotoxic chemotherapeutic agent (docetaxel) and a cyclooxygenase (Cox 2) inhibitor (celecoxib), as single agents or combinations. Since the start of the trial, a number of new research arms have been added to STAMPEDE over time to evaluate: abiraterone, a steroid synthesis inhibitor; prostate radiotherapy for patients with newly diagnosed metastatic disease; enzalutamide, an inhibitor of androgen receptor signalling, given with abiraterone; and metformin, an anti-diabetic medication and transdermal oestradiol, to be given as an alternative form of ADT.

Objectives:

Primary

To compare the safety and efficacy of novel therapeutic strategies against the current standard-of-care for men with high-risk locally advanced or metastatic prostate cancer starting long-term ADT for the first time.

Outline: This is a randomised, controlled, multi-centre MAMS trial platform. Patients are current randomised to 1 of 3 arms: control group (arm A), metformin treatment group (arm K) and transdermal oestradiol (Arm L). The other arms are all closed to recruitment with results known for all the original comparisons and awaited for others added since the trial commenced.

Patient population: STAMPEDE recruits both men with high-risk locally advanced prostate cancer and men with metastatic prostate cancer, all of whom must be starting long-term ADT for the first time. Patients who received previous radical treatment and are now relapsing with high-risk features are also eligible.

Follow-up: All patients are follow-up life long

Sub-studies: There are several translational sub-studies ongoing as part of STAMPEDE. Participation is optional. These currently include several translational sub-studies involving sample collection: saliva collection for germline DNA analysis, sequential circulating tumour DNA analysis and FFPE tumour block retrieval for DNA and RNA analysis. Other sub-studies include a QOL sub-study and an imaging sub-study.
