Study summary

A randomized controlled open-label trial in patients with high risk prostate cancer. Eligible and consenting patients will be randomly allocated to receive stereotactic body radiotherapy (SBRT) boost to prostate or conventional radiotherapy boost to prostate in 1:1 ratio. Prostate radiotherapy boost will be administered after standard pelvic radiotherapy. Subjects will be followed for 24 months post radiation treatment for Quality of Life assessment and toxicity.

Read the detailed description

In this study we investigate stereotactic body radiotherapy (SBRT) as a boost radiotherapy treatment, following pelvic radiotherapy, in patients with high risk prostate cancer (PrCa) treated with Androgen Deprivation Therapy (ADT). One hundred patients with localized high risk PrCa will receive ADT for a total of 3 years. Three months after initiation of ADT all patients will receive pelvic (lymph node and prostate) treatment of 45Gy in 25 fractions (5 days per week). Then patients will be randomized to receive either The conventional radiotherapy (CRT) of 33 - 35 Gy in 16 fractions (5 days per week - over 22 days) (comparator arm) or SBRT boost treatment of 19.5 - 21 Gy in three fractions (1 treatment per week - over 22days) (experimental arm). SBRT boost treatment will be delivered with either cyberknife or VMAT technique.

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

What researchers measure

Primary outcomes

  1. Short Term Quality of Life (QoL)

    To compare early QoL (up to 6 months post RT) in patients with high risk adenocarcinoma of the prostate treated with ADT and RT in the form of pelvic nodal irradiation and prostate boost with standard fractionation, or pelvic nodal irradiation and prostate boost with SBRT using Cyberknife or VMAT. QoL, defined as bowel and bladder function and bother after PrCa treatment, will be measured prior to and at regular intervals after completion of radiotherapy using the established Prostate QoL (The Expanded Prostate cancer Index Composite (EPIC-26 instrument)). Higher EPIC score represent a better outcome

    Time frame: up to 6 months post radiation

Secondary outcomes

  1. Long Term Quality of Life (QoL)

    long term QoL QoL, defined as bowel and bladder function and bother after PrCa treatment, will be measured prior to and at regular intervals up to 24 months month after completion of radiotherapy using the established Prostate QoL (The Expanded Prostate cancer Index Composite (EPIC-26 instrument)). Higher EPIC score represent a better outcome

    Time frame: 24 months

  2. Urinary function assessment

    short and long term quality of urinary function (The International Prostate Symptom Score (IPSS)). Total IPSS is between 1-35 / lower score shows better function.

    Time frame: 24 months

  3. Late Toxicity

    Grade 2-4 treatment related late (12-24 months), bladder and bowel related toxicity evaluated by the Expanded Common Toxicity Criteria of the National Cancer Institute of Canada (NCI)

    Time frame: 12-24 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2019 (actual). Primary completion is estimated for Jan 2022, 36 months after the start.

Of 610 non-industry phase 2 interventional studies under Prostatic Neoplasms, half reached primary completion within 57 months of starting (the median), counting those still running; a quarter within 39 and three quarters within 86. This study's planned 36 months is below that.

Counting every sponsor, half of 724 studies reached it within 53 months; a quarter within 34 and three quarters within 80.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 4, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
