Summary

This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.

Description

PRIMARY OBJECTIVE:

I. Compare metastasis-free survival (MFS) of salvage radiation therapy (RT) and gonadotropin releasing hormone (GnRH) agonist/antagonist versus (vs.) RT/GnRH agonist/antagonist with apalutamide for patients with pathologic node-positive prostate cancer after radical prostatectomy with detectable prostate-specific antigen (PSA).

SECONDARY OBJECTIVES:

I. Compare health-related quality of life (Expanded Prostate Cancer Index Composite [EPIC]-26, EuroQol [EQ]-5 Dimension [D]-5 Level [L]), Brief Pain Inventory, Patient Reported Outcome Measurement Information System [PROMIS]-Fatigue) among the treatment arms.

II. Compare overall survival, biochemical progression-free survival, time to local-regional progression, time to castrate resistance, and cancer-specific survival among the treatment arms.

III. Compare the short-term and long-term treatment-related adverse events among the treatment arms.

EXPLORATORY OBJECTIVES:

I. Validate Decipher score for an exclusively node-positive population and use additional genomic information from Affymetrix Human Exon 1.0st array to develop and validate novel prognostic and predictive biomarkers.

II. Validate the PAM50-based classification of prostate cancer into luminal A, luminal B, and basal subtypes as prognostic markers and determine whether the luminal B subtype is a predictive marker for having a larger improvement in outcome from the addition of apalutamide.

III. To optimize quality assurance methodologies and processes for radiotherapy and imaging with machine learning strategies.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive standard of care hormone therapy per physician discretion for 24 months. Patients also undergo standard of care pelvis and prostate bed radiation therapy 5 days per week over 5-6 or 7-8 weeks beginning within 90 days of randomization in the absence of disease progression or unacceptable toxicity.

ARM II: Patients undergo standard of care hormone therapy and radiation therapy as in Arm I. Patients also receive apalutamide orally (PO) once daily (QD) on days 1-90. Cycles repeat every 90 days for 8 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 3 years, then annually thereafter.

Eligibility

 Yes No Not Sure

Inclusion Criteria

Pathologically (histologically) proven diagnosis of prostate adenocarcinoma. Any type of radical prostatectomy is permitted, including retropubic, perineal, laparoscopic or robotically assisted
Any T-stage is eligible (American Joint Committee on Cancer [AJCC] 8th edition [ed])
Appropriate stage for study entry based on fluciclovine F-18 positron emission tomography (PET) scan (FACBC, Axumin) within 90 days prior to registration that is negative for distant metastatic (M1a, M1b, M1c) disease; Note that though every effort should be made to obtain a fluciclovine F-18 PET (FACBC, Axumin) scan; however, if the patient has already had a recent F-18 PSMA PET scan or gallium Ga 68-labeled PSMA-11 (Ga-68 PSMA) PET scan or C-11 or F-18 choline PET scan within 90 days prior to registration (to include scan report) then repeat molecular imaging with a fluciclovine F-18 PET (FACBC, Axumin) scan will not be required
Pathologically node positive disease with nodal involvement only in the pelvis in the prostatectomy specimen (including external iliacs, internal iliacs, and/or obturator nodes); peri-rectal nodes can also be considered regional lymphadenopathy and are allowed
History/physical examination within 90 days prior to registration
Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 within 90 days prior to registration
Detectable PSA after radical prostatectomy. Detectable PSA is defined as serum PSA > 0 ng/mL at least 30 days after prostatectomy and within 180 days of registration and before start of GnRH agonist/antagonist
Patients who have already started on post-prostatectomy GnRH agonist/antagonist for =< 180 days prior to registration are eligible (Note: patients who started on an oral antiandrogen are eligible if started =< 180 days and stopped prior to registration)
Hemoglobin >= 9.0 g/dL, independent of transfusion and/or growth factors (within 90 days prior to registration)
Platelet count >= 100,000 x 10^9/uL independent of transfusion and/or growth factors (within 90 days prior to registration)
Serum potassium >= 3.5 mmol/L within 90 days prior to registration
Creatinine clearance (CrCl) >= 30 mL/min estimated by Cockcroft-Gault (please use actual weight for calculation unless greater than 30% above ideal body weight then use the adjusted body weight) (within 90 days prior to registration)
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (Note: In subjects with Gilbert's syndrome, if total bilirubin is > 1.5 x ULN, measure direct and indirect bilirubin and if direct bilirubin is =< 1.5 x ULN, subject is eligible) (within 90 days prior to registration)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) or alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional ULN (within 90 days prior to registration)
