About this study

Official title: Genomics in Michigan Impacting Observation or Radiation (G-MINOR)

To determine the impact of Decipher test results on adjuvant treatment decisions of high-risk post-RP patients with undetectable post-op prostate specific antigen (PSA) compared to clinical factors alone.

Read the detailed description

This prospective, randomized trial will compare the receipt of adjuvant therapy for high-risk radical prostatectomy (RP) patients who undergo Decipher testing to those who do not. 350 subjects from within the statewide Michigan Urological Surgery Improvement Collaborative (MUSIC) will be randomized to either a Genomic Classifier (Decipher) or Usual-Care-Based (UC) strategy for a period of three months. If enrolled during the Genomic Classifier period, both subjects and their treating physician will be provided Decipher results and CAPRA-S scores. In the UC periods, CAPRA-S scores but not Decipher results will be provided.

The enrollment goal, initially and throughout the study, was to enroll 350 evaluable patients. During the study, the target accrual goal was raised to 550 patients to allow more flexibility among sites to achieve the enrollment goal of 350 evaluable patients.

What participants receive

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

  • Decipher Prostate Cancer ClassifierOther

    Also called Decipher Post-Op

    The Decipher test (GenomeDx Biosciences, San Diego, CA) is a genomic test that predicts high grade disease, the probability of metastasis and prostate cancer-specific mortality for men with prostate cancer.

Study groups in NCT02783950
Study groupRoleWhat they receive
GC (Decipher) ArmOtherIf enrolled during the Genomic Classifier (GC) period, both subjects and their treating physician will be provided GC (Decipher Prostate Cancer Classifier from GenomeDx) and CAPRA-S scores following prostatectomy.
Receives: Other: Decipher Prostate Cancer Classifier
Usual-Care-Based (UC) ArmNo interventionIf enrolled during the UC period, only the CAPRA-S results will be provided.

What is being measured

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

  1. Number of Participants That Receive Adjuvant Therapy (Radiation and/or Hormone Therapy)

    Adjuvant will be defined as preceding biochemical recurrence (BCR) (i.e.: PSA ≥ 0.2 ng/ml) and within 18 months of radical prostatectomy.

    Measured: within 18 months of radical prostatectomy

Secondary outcomes (5)
  1. Time (From Randomization) to Adjuvant Treatment Administration

    Adjuvant treatment (radiation and/or hormone) is defined as preceding BCR. BCR occurs when prostate specific antigen (PSA) ≥ 0.2 ng/ml.

    Measured: Up to 18 months post randomization

  2. Time (From Randomization) to Salvage Treatment Administration

    Salvage treatment (radiation and/or hormone therapy) is defined as either after BCR or >18 months after surgery in the absence of documented BCR

    Measured: Up to 5 years post randomization

  3. Time (From Randomization) to Biochemical Recurrence (BCR)

    BCR is defined as PSA ≥ 0.2 ng/ml.

    Measured: Up to 5 years post randomization

  4. Time (From Randomization) to Metastatic Disease (Regional or Distant)

    Metastasis is determined based on CT, MRI, bone scan, and/or positron emission tomography (PET) scan

    Measured: Up to 5 years post randomization

  5. Michigan Urological Surgery Improvement Collaborative (MUSIC) Patient Reported Outcomes (PRO)

    Composite Expanded Prostate Cancer Index Composite (EPIC)-26 domain scores for a) urinary irritative function, b) urinary incontinence, and c) sexual function will be measured at baseline and 24 months post-radical prostatectomy. Each of the 3 domains is scaled from 0-100 (higher is better).

    Measured: Up to 24 months post radical prostatectomy

Questions about this trial

What is this clinical trial studying?

A study testing Decipher Prostate Cancer Classifier in people with Prostate Cancer, run by University of Michigan Rogel Cancer Center at 13 sites in United States.

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 6 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: finished, as of the sponsor's last update on 26 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States. 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?

Yes. Results are posted in the registry (first posted 25 Feb 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants That Receive Adjuvant Therapy (Radiation and/or Hormone Therapy) (time frame: within 18 months of radical prostatectomy). 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 NCT02783950, which also lists 23 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 26 Sep 2024.
