Brief Summary:
This phase III trial compares the addition of apalutamide, with or without targeted radiation therapy, to standard of care treatment versus standard of care treatment alone in patients with prostate cancer biochemical recurrence (a rise in the blood level of prostate-specific antigen [PSA] after treatment with surgery or radiation). Diagnostic procedures, such as positron emission tomography/computed tomography (PET/CT), may help doctors look for cancer that has spread to the pelvis. Androgens can cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET/CT results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.

Primary Outcome Measures :
  1. Progression-free survival (PFS) [ Time Frame: From randomization to radiographic progression by conventional imaging, symptomatic disease or death, whichever occurs first, assessed up to 10 years ]
    The power of the PFS analysis is 85% using one-sided 0.025 level stratified logrank test. The overall type I error will be controlled using an O'Brien-Fleming boundary function

  2. PFS prolongation in patients without positron emission tomography (PET)-evidence of extrapelvic metastases [ Time Frame: Up to 10 years ]
    Will evaluate whether the addition of enhanced systemic therapy to standard of care salvage therapy could prolong PFS in this patient population. Will be an intention-to-treat analysis of all randomized patients and performed in parallel with patients with PET-evidence of extrapelvic metastases.

  3. PFS prolongation in patients with PET-evidence of extrapelvic metastases [ Time Frame: Up to 10 years ]
    Will evaluate whether the addition of metastasis-directed radiation therapy to standard of care salvage therapy and enhanced systemic therapy could prolong PFS in this patient population. Will be an intention-to-treat analysis of all randomized patients and performed in parallel without patients with PET-evidence of extrapelvic metastases.


Secondary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: From randomization to death or date last known alive, assessed up to 10 years ]
    Will be characterized by the method of Kaplan and Meier and a logrank test will be used to compare OS between the two arms in each cohort.

  2. Event-free survival [ Time Frame: From randomization to radiographic progression by conventional imaging, PET progression in the setting of rising PSA, symptomatic disease, initiation of new treatment for the disease or death, whichever occurs first, assessed up to 10 years ]
    Will be characterized by the method of Kaplan and Meier and a logrank test will be used to compare EFS between the two arms in each cohort.

  3. Time to prostate-specific antigen (PSA) progression [ Time Frame: From randomization to documented PSA progression or last disease assessment that shows free of PSA progression, assessed up to 10 years ]
    Will be characterized by the method of Kaplan and Meier and a logrank test will be used to compare time to PSA progression between the two arms in each cohort.

  4. Incidence of adverse events [ Time Frame: Up to 10 years ]
    Toxicity will be defined using the Common Terminology Criteria for Adverse Events.

  5. Detection rate of fluciclovine F18 (18F-fluciclovine) PET/computed tomography (CT) [ Time Frame: At time of PSA recurrence or 12 months after completion of enhanced systemic therapy (whichever occurs first), assessed up to 10 years ]
    For the detection rate, the proportion of baseline standard of care 18F-fluciclovine PET/CT (PET1) positive results at the patient and regional (prostate fossa, intrapelvic soft tissue/lymph node, extrapelvic soft tissue/lymph node, and bone metastases) level will be calculated and its 95% confidence interval will be estimated using the Exact method based on the binomial distribution.

  6. Concordance of detection rate with the follow-up conventional imaging modalities (CIM) [ Time Frame: At time of PSA recurrence or 12 months after completion of enhanced systemic therapy (whichever occurs first), assessed up to 10 years ]
    Will use Cohen's Kappa coefficient to measure the agreement between dichotomized PET/CT results and the dichotomized CIM results. Baseline CIM comparison will not be performed because as per our study eligibility criteria, baseline CIM will be negative for metastases.

  7. Distribution of 18F-fluciclovine PET-positive lesions among anatomic sites [ Time Frame: Baseline ]
    The rate of 18F-fluciclovine PET-positive lesions will be reported for each anatomic site, including prostate fossa, intrapelvic soft tissue/lymph node, extrapelvic soft tissue/lymph node, and bone metastases. Their confidence intervals will be estimated using the Exact method for the binomial distribution. To evaluate if PSA (level, doubling time, velocity) and other relevant clinical parameters affects the positivity distribution, will use the logistic regression to model with the binary outcome (positive vs. negative from PET/CT) and covariates will include anatomic site, PSA, and other clinical parameters. Will test the interactions between anatomic site and PSA (plus other clinical parameters) to see if the positivity distribution across anatomic site may change according to the levels of the interacted terms. Will use the technique of generalized estimating equation to account for the outcome correlations within subjects.

  8. Value of repeat PET to assess response to therapy compared to standard response assessments [ Time Frame: At time of PSA recurrence or 12 months after completion of enhanced systemic therapy (whichever occurs first), assessed up to 10 years ]
    Analyses will be conducted to evaluate qualitative visual evidence of 18F-fluciclovine PET positive metastatic lesions and quantitative PET standardized-uptake value (SUV) changes on a lesion-to-lesion basis from 18F-fluciclovine PET1 (baseline) to PET2 on visually determined sites of recurrence and metastatic disease. This will be compared to reference standard-of-care conventional imaging (Prostate Cancer Working Group 2 criteria) and PSA response at PET2 time point to determine PET2 response to therapy. PET2 visual and quantitative assessment will also be compared to PFS in the time-to-event analysis using a log-rank test (PET2 visual assessment) and a Cox proportional hazards regression (PET2 quantitative assessment). PET SUV parameters to be obtained at PET1 and PET2 will include SUVmax, SUVpeak. PET SUV change from PET1 to PET2 will include absolute SUVmax and SUVpeak change (PET2-PET1) and percent change of SUVmax and SUVpeak (% change = 100*[(PET2-PET1)/PET1]).)
