Prostate Cancer Clinical Trial
Treating Prostate Cancer That Has Come Back After Surgery With Apalutamide and Targeted Radiation Using PET/CT Imaging
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.
Full Description
PRIMARY OBJECTIVES:
I. For patients without PET-evidence of extrapelvic metastases, to evaluate whether the addition of enhanced systemic therapy to standard of care (SOC) salvage radiation therapy (RT) could prolong progression-free survival (PFS).
II. For patients with PET-evidence of extrapelvic metastases, to evaluate whether the addition of metastasis-directed RT to enhanced systemic therapy and SOC salvage RT could prolong PFS.
SECONDARY OBJECTIVES:
I. To evaluate overall survival (OS) in each arm. II. To evaluate event-free survival (EFS) in each arm. III. To evaluate time to prostate-specific antigen (PSA) progression using Prostate Cancer Working Group (PCWG) 2 criteria in each arm.
IV. To assess the incidence of adverse events with the addition of enhanced systemic therapy in patients without PET-evidence of extrapelvic metastases.
V. To assess the incidence of adverse events with local ablative metastasis-directed RT for PET-positive metastatic disease in patients with PET-evidence of extrapelvic metastases.
VI. To estimate the detection rate of PET/CT at the patient and regional level, and to evaluate its concordance with the follow-up Food and Drug Administration (FDA)-approved conventional imaging modalities (CIM) considered standard-of-care per institution, including CT, bone scintigraphy, magnetic resonance imaging (MRI) and PET imaging performed as PET/CT and/or PET/MR using 11C-choline and/or 18F-sodium fluoride.
VII. To determine the distribution of PET-positive lesions among anatomic sites (prostate fossa, intrapelvic soft tissue/lymph node, extrapelvic soft tissue/lymph node, and bone metastases) in patients with post-radical prostatectomy (RP) biochemical recurrence (BCR), correlated with PSA (level, doubling time, velocity) and other relevant clinical parameters.
VIII. To determine the value of repeat PET at 12 months (PET2) to assess response to therapy (enhanced systemic therapy +/- focal RT and/or androgen deprivation therapy [ADT]) compared to standard response assessments (PSA and CIM).
OUTLINE:
STEP 0: Patients receive fluciclovine F18 intravenously (IV) and undergo SOC PET/CT scan at baseline. NOTE: Patients randomized to Arms C or D below undergo a repeat fluciclovine F18 PET/CT at time of second PSA recurrence or 12 months after completion of enhanced systemic therapy.
STEP 1: Patients are randomized to 1 of 4 arms based on results of fluciclovine F18 PET/CT in Step 0.
ARM A (PET NEGATIVE FOR EXTRA PELVIC-METASTASES): Patients undergo SOC external beam radiation therapy (EBRT) for 6 months. Patients also receive goserelin acetate subcutaneously (SC) or leuprolide acetate intramuscularly (IM) for 6 months starting up to 3 months prior to EBRT but no later than the first fraction of EBRT. All treatment continues for 6 months in the absence of disease progression or unacceptable toxicity.
ARM B (PET NEGATIVE FOR EXTRA PELVIC-METASTASES): Patients undergo SOC EBRT and receive goserelin acetate SC or leuprolide acetate IM as in Arm A. Patients also receive apalutamide orally (PO) once daily (QD) for 6 months in the absence of disease progression or unacceptable toxicity.
ARM C: (PET POSITIVE FOR EXTRA PELVIC-METASTASES): Patients undergo SOC EBRT and receive goserelin acetate SC or leuprolide acetate IM as in Arm A. Patients also receive apalutamide PO QD as in Arm B.
ARM D (PET POSITIVE FOR EXTRA PELVIC-METASTASES): Patients undergo SOC EBRT and receive goserelin acetate SC or leuprolide acetate IM as in Arm A and apalutamide PO QD as in Arm B. Patients also undergo stereotactic body radiation therapy (SBRT) or 3-dimensional (3D) conformal radiation therapy (CRT), intensity-modulated radiation therapy (IMRT) (including volume modulated arc therapy [VMAT]), and intensity-modulated proton therapy (IMPT) over 3-5 fractions in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for years 1-3 and then every 6 months for years 4-5.
Eligibility Criteria
Inclusion Criteria:

Patient must have had a radical prostatectomy (RP) as definitive therapy for histopathologically-proven prostatic adenocarcinoma
Patient must have biochemical recurrence (BCR) after RP, with rising PSA defined as follows:
If time to biochemical recurrence, (defined as time to first detectable PSA after RP) is < 12 months, a minimum PSA level of >= 0.2 ng/mL and a confirmatory reading of >= 0.2 ng/mL is required, per the American Urological Association (AUA) definition (this includes patients with a persistent PSA reading of at least 0.2 ng/mL)
