About this study

Official title: Neoadjuvant Apalutamide (ARN509) and Radical Prostatectomy in the Treatment of Intermediate to High Risk Prostate Cancer

This is an investigator-initiated phase II single arm trial, combining neoadjuvant apalutamide (ARN509) with radical prostatectomy, in the treatment of D'Amico intermediate to high risk organ-confined prostate cancer. Apalutamide has shown efficacy in castrate resistant prostate cancer in phase II studies and are now in phase III trials combined with radiation in organ confined disease.

The primary study objectives include assessment of (i) oncological efficacy as determined by tumour downstaging and achievement of nadir PSA The secondary study objectives include(i) determination of adverse effects related to apalutamide and surgical complication rates (ii) human prostate tissue effect of apalutamide

The study will recruit thirty eligible participants who will receive 12 weeks of oral apalutamide 240mg daily. This will be followed by standard-of-care radical prostatectomy. The total trial duration is 26 weeks.

Read the detailed description

This is a phase II single arm study looking at the efficacy of 12 weeks of neoadjuvant apalutamide (ARN 509), combined with standard-of-care radical prostatectomy, for D'Amico intermediate to high risk prostate cancer patients. The phases of the study will include: screening, treatment and follow-up phases.

Safety will be monitored throughout the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients with pathological downstaging after neodjuvant apalutamide followed by radical prostatectomy

    This is described as residual cancer burden and treatment response group on histopathology after neoadjuvant apalutamide and radical prostatectomy

    Measured: 24 weeks

  2. Proportion of patients with biochemical treatment response following neoadjuvant apalutamide and radical prostatectomy

    Patients who attain serum PSA levels below 0.03microg/L

    Measured: 24 weeks

Secondary outcomes (2)
  1. Proportion of patients who report significant adverse effects after 12 weeks of neoadjuvant apalutamide

    Adverse effects as defined by CTCAE criteria grade 3 and above

    Measured: 12 weeks

  2. The proportion of patients with peri-operative complications following neoadjuvant apalutamide and radical prostatectomy

    The level of complications defined by Clavien-Dindo classification

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Apalutamide in people with Cancer of the Prostate, run by Singapore General Hospital at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with pathological downstaging after neodjuvant apalutamide followed by radical prostatectomy (time frame: 24 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03124433, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2020.
