Study summary

Testing if short-term use of apalutamide can reduce image defined tumour volumes in men with detectable lesion on multi-parametric Magnetic Resonance Imaging (mpMRI) and being managed by Active Surveillance. The trial will also evaluate the tolerability and side effect profile of men on AS using short term apalutamide and patient acceptability as a therapeutic strategy, as well as determining feasibility of a larger prospective randomised trial of apalutamide.

Read the detailed description

The numbers of men diagnosed with prostate cancer in the United Kingdom (UK) and worldwide is increasing. In the UK 46,690 men were diagnosed in 2014 alone and it is estimated this figure will be closer to 70,000 by 2030. A significant proportion of these men will present with organ confined and low or intermediate risk disease. There is increasing recognition that many men with low and intermediate risk prostate cancer do not need immediate radical therapy.

There is sufficient evidence that pharmacological intervention used as short-term therapy in men with low to intermediate-risk disease can inhibit the growth of prostate tumours and delay or remove the need for radical therapy in men managed by active surveillance. Given the irrefutable role of the androgen receptor in prostate cancer pathogenesis it is logical to target this pathway as a method of inhibiting or delaying disease progression.

This window study will be built on the known anti-androgen effects of apalutamide and investigate the efficacy of using it as a short intervention strategy to cause a physiological change in the tumour by reducing its volume. Tumour volume can be measured using the well-established place of mpMRI defined tumour volumes as a surrogate of disease presence and change. The rationale for a short duration treatment is that it will not have the long term debilitating effects of androgen deprivation on general health and prevent the onset of androgen resistance.

It is anticipated that if successful, this approach could be a new therapeutic strategy for these men who otherwise are living and waiting for their disease to progress or not.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Given (IC) to participate
  • Age 18 or over
  • (ECOG) status 0-2

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
