Study summary

This is a prospective study to measure the impact on first-line therapy of genomic testing of biopsy tissue from recently diagnosed treatment-naïve patients with early stage localized prostate cancer.

Read the detailed description

This is a prospective study to measure the impact on first-line therapy of genomic testing of biopsy tissue from recently diagnosed treatment-naïve patients with early stage localized prostate cancer. Multiple individual VAMC sites will participate in PART 1 of the study. During PART 1 of the study, a three-part questionnaire will be completed to evaluate the PRE-Prolaris test treatment plan, the POST-Prolaris test treatment plan, and the ACTUAL treatment option. Using PRE-Prolaris Test Questionnaire #1 the physician will record the recommendation for first-line therapy based on standard clinical-pathological parameters (PSA, Gleason score, clinical stage and percent positive cores). The likelihood of recommending a non-interventional therapy approach will also be recorded using a 10-point ordinal scale. A sample of the biopsy tissue will then be tested using the Prolaris® genomic test and a relative cancer aggressiveness score will be shared with the physician. After reviewing and considering the results of the genomic testing and after patient consultation, the physician will complete POST-Prolaris Questionnaire #2 documenting the planned treatment ( interventional treatment or non-interventional). Approximately 6 months from the date of the test results, ACTUAL Treatment Questionnaire #3 will be completed to document the actual treatment administered.

PART 2 of this study is a prospective evaluation of the prognostic utility of Prolaris® testing of prostate biopsy samples obtained from men who participate in PART 1of the study and who undergo radical prostatectomy or radiation therapy or who are managed with WW or AS. The central VAMC site will be responsible for PART 2; individual VAMC sites will not participate in this part of the study. Patients will be followed using medical record review every 6 months for objective progression (BCR, radiographic or radionuclide evidence of metastases or disease specific mortality) through 5 years.

Study population

Newly diagnosed, clinically localized treatment naïve prostate cancer patients in the US clinical setting

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

  • Newly diagnosed (\<= 6 months), untreated patients with proven adenocarcinoma of the prostate
  • Final treatment decision has not been made (that is all treatment options are feasible and none have been ruled out due to comorbidities at study entry)
  • Clinically localized (no evidence on clinical or imaging studies of advanced disease)
  • No hormonal therapy for treatment of prostate cancer including LHRH agonist or antagonist, anti-androgen, estrogens or exogenous androgens when applicable (use of 5-alpha reductase inhibitors is acceptable)
  • Sufficient amount of tissue remains from to perform genomic testing
  • Life expectance of a minimum of 10 years
  • Men who completed PART 1 and were treated with radical prostatectomy (including robotic, laparoscopic, open retropubic or perineal) or receive radiation therapy or were placed on AS or WW.

Exclusion criteria

Exclusion Criteria:

  • Men with clinical node positive or disease
  • Men with a known baseline total serum testosterone level of \<100 ng/dL prior to radiation or hormone therapy (men with unknown baseline testosterone levels will not be excluded)
  • Men who previously received pelvic radiotherapy for another
  • Non adenocarcinoma prostate cancer histologies
Terms in these criteria, in plain language(4)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

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.

Metastases

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

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.

What researchers measure

Primary outcomes

  1. Impact of Prolaris on the magnitude of change between Pre-Prolaris treatment selection and the actual implemented treatment

    Comparison of percentage change from the Pre-Prolaris test treatment option (based on standard clinical pathological parameters) versus the actual treatment option implemented following results of Prolaris

    Time frame: 6 months

  2. Prolaris prediction of biochemical or objective recurrence

    Biochemical recurrence (defined as PSA \>0.2 ng/ml or by Phoenix definition) or objective recurrences of disease by 5 years following definitive therapy with curative intent in men treatment with radical prostatectomy or radiation therapy

    Time frame: 5 years

Other outcomes

  1. Prolaris prediction of who benefits from the addition of hormone therapy to contemporary radiation therapy

    either biochemical or objective recurrences of disease following definitive therapy with curative intent in men treated with radiation who did or did not receive adjuvant ADT

    Time frame: 5 years

  2. Comparison of prognostic utility of prospective Prolaris testing of prostate biopsy samples to other clinical pathological parameters with respect to disease progression

    either biochemical or objective recurrences of disease following definitive therapy with curative intent in men treated with radical prostatectomy or radiation

    Time frame: 5 years

  3. Association of Prolaris score with progression to active intervention when initially managed with AS or WW

    Progression to interventional therapy in men initially managed with AS or WW

    Time frame: 5 years

  4. Prognostic utility of Prolaris testing compared to other clinical pathological parameters with respect to disease progression in men who were Gleason score <7 on initial biopsy

    biochemical or objective recurrence of disease in men who were Gleason score \<7

    Time frame: 5 years

  5. Impact of Prolaris on magnitude of change between pre-Prolaris treatment selection and the post-Prolaris treatment plan following consultation with the patient

    comparison of percentage change from the pre-Prolaris treatment option versus the post-Prolaris treatment plan

    Time frame: 3 months

  6. Impact of Prolaris on magnitude of change between physician likelihood of recommending non-interventional therapy and the likelihood following the genomic test results

    mean change in the physician's likelihood of recommending watchful waiting or active surveillance post-genomic testing compared to pre-genomic testing

    Time frame: 3 months

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 13, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
