About this study

Official title: Randomized Feasibility Trial of Prostate Radiotherapy vs Prostatectomy in Men With Hormone Sensitive Oligometastatic Prostate Cancer

Patients with hormone sensitive oligometastatic prostate cancer (≤ 5 metastatic tumours outside of regional pelvic nodes with no more than 3 in any organ system) and no previous treatment to prostate will be treated with intermittent androgen deprivation therapy +/- chemotherapy, stereotactic radiotherapy to all metastases, and either radical prostatectomy or radiotherapy.

Read the detailed description

Investigators propose to do a randomized feasibility trial comparing RP vs RT to the prostate in the setting of hormone sensitive oligometastatic prostate cancer. SBRT will be used to treat all of the metastases, and this will be combined with an intermittent ADT approach. Adding systemic chemotherapy will be allowed. Given the past difficulties of randomizing patients between RP and RT in localized prostate cancer studies (like SPIRIT), investigators feel a small feasibility project is the first step. In the setting of metastatic disease, where radical treatment is not routine standard of care, we hope that patients will be more inclined to accept randomization. If patients do not accept their assigned randomization (ie they prefer RP even though they are randomized to RT, or vice versa), they will still be treated with their prostate intervention of choice and followed for their outcomes.

Being tested
Radical prostatectomy, HDR (19Gy) or SBRT (35-40Gy)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radical prostatectomyProcedure or surgery

    Radical prostatectomy

  • HDR (19Gy) or SBRT (35-40Gy)Radiation

    Patients will receive HDR unless judged to medically unfit to undergo HDR brachytherapy, in which case they will receive SBRT

What is being measured

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

  1. Patients willing to accept their randomization

    Patients willing to accept their randomization will be measured as a proportion.

    Measured: 2 years

Secondary outcomes (6)
  1. Toxicity

    Acute and late toxicities will be measured using CTCAE v4.0 and will be reported as percentages.

    Measured: 7 years

  2. Efficacy

    Time to CRPC will be calculated using Kaplan Meier methodology.

    Measured: 7 years

  3. Efficacy

    Progression free survival will be calculated using Kaplan Meier methodology.

    Measured: 7 years

  4. Efficacy

    Local control will be calculated using Kaplan Meier methodology.

    Measured: 7 years

  5. Efficacy

    Distant control will be calculated using Kaplan Meier methodology.

    Measured: 7 years

  6. Efficacy

    Overall survival will be calculated using Kaplan Meier methodology.

    Measured: 7 years

Questions about this trial

What is this clinical trial studying?

A study testing Radical prostatectomy and HDR (19Gy) or SBRT (35-40Gy) in people with Hormone Sensitive Oligometastatic Prostate Cancer, run by Dr. Patrick Cheung at 1 site in Canada.

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 7 inclusion and 4 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: withdrawn, as of the sponsor's last update on 1 Dec 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 Canada. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Patients willing to accept their randomization (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Dec 2020.
