Study Description

Brief Summary

This phase III trial uses the Decipher risk score to guide intensification (for higher Decipher gene risk) or de-intensification (for low Decipher gene risk) of treatment to better match therapies to an individual patient's cancer aggressiveness. The Decipher risk score evaluates a prostate cancer tumor for its potential for spreading. In patients with low risk scores, this trial compares radiation therapy alone to the usual treatment of radiation therapy and hormone therapy (androgen deprivation therapy). Radiation therapy uses high energy x-rays or particles to kill tumor cells and shrink tumors. Androgen deprivation therapy blocks the production or interferes with the action of male sex hormones such as testosterone, which plays a role in prostate cancer development. Giving radiation treatment alone may be the same as the usual approach in controlling the cancer and preventing it from spreading, while avoiding the side effects associated with hormonal therapy. In patients with higher Decipher gene risk, this trial compares the addition of darolutamide to usual treatment radiation therapy and hormone therapy, to usual treatment. Darolutamide blocks the actions of the androgens (e.g. testosterone) in the tumor cells and in the body. The addition of darolutamide to the usual treatment may better control the cancer and prevent it from spreading.

Detailed Description

PRIMARY OBJECTIVES:
  1. To determine whether men with National Comprehensive Cancer Network (NCCN) unfavorable intermediate risk (UIR) prostate cancer and lower Decipher genomic risk (Decipher score < 0.40) treated with radiation therapy (RT) alone instead of 6 months androgen deprivation therapy (ADT) + RT experience non-inferior rate of distant metastasis. (De-intensification study) II. To determine whether men with NCCN UIR prostate cancer who are in the higher genomic risk (Decipher score >= 0.40) will have a superior metastasis-free survival through treatment intensification with darolutamide added to the standard of RT plus 6 months ADT. (Intensification study)

OUTLINE:

DE-INTENSIFICATION STUDY: Patients with Decipher score < 0.40 are randomized to 1 of 2 arms.

ARM I: Patients undergo RT using a recognized regimen (2-3 days a week or 5 days a week for 2-11 weeks) in the absence of disease progression or unacceptable toxicity.

ARM II: Patients undergo RT as Arm I. Patients also receive ADT consisting of leuprolide, goserelin, buserelin, histrelin, triptorelin, degarelix, or relugolix at the discretion of the treating physician, for 6 months in the absence of disease progression or unacceptable toxicity. Patients may also receive bicalutamide or flutamide for 0, 30 or 180 days.

INTENSIFICATION STUDY: Patients with Decipher score >= 0.40 are randomized to 1 of 2 arms.

ARM III: Patients receive treatment as in Arm II.

ARM IV: Patients receive RT and ADT as in Arm II. Patients also receive darolutamide orally (PO) twice daily (BID). Treatment repeats every 90 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 3, 6, 12, 24, 36, 48 and 60 months.

    7. Time to testosterone recovery [From randomization until T > 200 ng/dL, assessed up to 5 years]

      Will be analyzed using competing-risk methods (Gooley 1999) where, in each case, death prior to occurrence of the event in question will be a competing risk. Changes in quality of life measures will be correlated with changes in testosterone levels.

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    Male
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • Pathologically (histologically or cytologically) proven diagnosis of adenocarcinoma of the prostate within 270 days prior to registration

    • Unfavorable intermediate risk prostate cancer, defined as having ALL the following bulleted criteria:

    • Has at least one intermediate risk factor (IRF):

    • PSA 10-20 ng/mL

    • Clinical stage T2b-c (digital rectal examination [DRE] and/or imaging) by American Joint Committee on Cancer (AJCC) 8th edition

    • Gleason score 7 (Gleason 3+4 or 4+3 [ International Society of Urological Pathology (ISUP) Grade Group 2-3])

    • Has ONE or more of the following 'unfavorable' intermediate-risk designators:

    • 1 immature reticulocyte fraction (IRF)

    • Gleason 4+3=7 (ISUP Grade Group 3)

    • = 50% of biopsy cores positive

    • Biopsies may include 'sextant' sampling of right/left regions of the prostate, often labeled base, mid-gland and apex. All such 'sextant' biopsy cores should be counted. Men may also undergo 'targeted' sampling of prostate lesions (guided by MRI, ultrasound or other approaches). A targeted lesion that is biopsied more than once and demonstrates cancer (regardless of number of targeted cores involved) should count as a single additional positive core sampled and positive. In cases of uncertainty, count the biopsy sampling as sextant core(s)

    • Absence of high-risk features

    • Appropriate stage for study entry based on the following diagnostic workup:

    • History/physical examination within 120 days prior to registration;

    • Negative bone imaging (M0) within 120 days prior to registration; Note: Tc-99m bone scan or sodium fluoride (NaF) positron emission tomography (PET) are allowed. Equivocal bone scan findings are allowed if plain films X-ray, computed tomography (CT) or magnetic resonance imaging (MRI) are negative for metastasis at the concerned site(s). While a negative fluciclovine, choline, or prostate specific membrane antigen (PSMA) PET may be counted as acceptable substitute for bone imaging, any suspicious findings must be confirmed and correlated with conventional imaging (Tc-99m bone scan, NaF PET, CT, X-ray, or MRI) to determine eligibility based on the latter modalities (e.g. M0 based on conventional imaging modalities)

    • Clinically negative lymph nodes (N0) as established by conventional imaging (pelvic +/- abdominal CT or MR), within 120 days prior to registration. Patients with lymph nodes equivocal or questionable by imaging are eligible if the nodes are =< 1.0 cm in short axis and/or if biopsy is negative.

    Note: While a negative fluciclovine, choline, or prostate specific membrane antigen (PSMA) PET may be counted as acceptable substitute for pelvic imaging, any suspicious findings must be confirmed by conventional imaging (CT, MRI or biopsy). If the findings do not meet pathological criteria based on the latter modalities (e.g. node =< 10 mm in short axis, negative biopsy), the patient will still be eligible

    • Age >= 18

    • Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 within 120 days prior to registration

    • Non-castrate testosterone level (> 50 ng/dL) within 120 days prior to registration

    • Absolute neutrophil >= 1,000 cells/mm^3 (within 120 days prior to registration)

    • Hemoglobin >= 8.0 g/dL, independent of transfusion and/or growth factors (within 120 days prior to registration)

    • Platelet count >= 100,000 cells/mm^3 independent of transfusion and/or growth factors (within 120 days prior to registration)

    • Creatinine clearance (CrCl) >= 30 mL/min estimated by Cockcroft-Gault equation (within 120 days prior to registration)

    • For African American patients specifically whose renal function is not considered adequate by the formula above, an alternative formula that takes race into account (Chronic Kidney Disease Epidemiology Collaboration CKD-EPI formula) should be used for calculating the related estimated glomerular filtration rate (GFR) with a correction factor for African American race creatinine clearance for trial eligibility, where GFR >= 30 mL/min/1.73m^2 will be considered adequate

    • Total bilirubin: 1.5 =< institutional upper limit of normal (ULN) (within 120 days prior to registration) (Note: In subjects with Gilbert's syndrome, if total bilirubin is > 1.5 x ULN, measure direct and indirect bilirubin. If direct bilirubin is less than or equal to 1.5 x ULN, subject is eligible)

    • Aspartate aminotransferase (AST)(serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT)(serum glutamate pyruvate transaminase [SGPT]): =< 2.5 x institutional ULN (within 120 days prior to registration)
