Current Secondary Outcome Measures  ICMJE
 (submitted: September 17, 2020)
  • Time to Prostate-Specific Antigen (PSA) Progression [ Time Frame: Up to 7 years ]
    Time to PSA progression is defined as the time from randomization to the date of first documentation of PSA progression. PSA progression is defined as a PSA concentration above the nadir of more than 0.5 nanogram per milliliter (ng/mL), confirmed by repeated measurement at least 3 Weeks later.
  • PSA Response Rate [ Time Frame: Up to 7 years ]
    PSA response rate is defined as the percentage of participants with a PSA decrease of >= 50 percent (%), >= 90% or undetectable from baseline.
  • PSA Levels at Week 26 [ Time Frame: Week 26 ]
    PSA levels at week 26 will be reported.
  • Time to Loco-Regional Progression by PSMA-PET [ Time Frame: Up to 7 years ]
    Time to loco-regional progression by PSMA-PET as assessed by blinded independent central review (BCIR) is defined as the time from randomization to the date of the first occurrence of PSMA-PET loco-regional progression. Criteria for PSMA-PET loco-regional progression: Appearance of at least one new PSMA-PET-positive loco-regional lesion compared with the previous scan.
  • Overall Survival [ Time Frame: Up to 7 years ]
    Overall survival is defined as the time from randomization to date of death from any cause.
  • Prostate Cancer-Specific Survival [ Time Frame: Up to 7 years ]
    Prostate cancer-specific survival is defined as the time from randomization to date of death due to prostate cancer.
  • Number of Participants With Adverse Event (AE) and Serious Adverse Events (SAEs) [ Time Frame: Up to 7 years ]
    An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the study vaccine. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. An SAE is any AE that results in: death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect and is a suspected transmission of any infectious agent via a medicinal product.

Descriptive Information
Brief Title  ICMJE A Study of Adding Apalutamide to Radiotherapy and LHRH Agonist in High-Risk Patients With Prostate-Specific Membrane Antigen-Positron Emission Tomography (PSMA-PET) Positive Hormone-Sensitive Prostate Cancer Participants
Official Title  ICMJE A Randomized, Controlled, Multicenter, Open-label Study to Investigate the Efficacy and Safety of Adding Apalutamide to Radiotherapy and LHRH Agonist in High-Risk Patients With PSMA-PET-Positive Hormone-Sensitive Prostate Cancer, With an Observational Follow-up of PSMA-PET-Negative Patients
Brief Summary The main purpose of this study is to determine if the addition of apalutamide to radiotherapy (RT) plus luteinizing hormone-releasing hormone agonist (LHRHa) delays metastatic progression as assessed by prostate specific membrane antigen-positron emission tomography (PSMA-PET) or death compared with RT plus LHRHa alone.
Detailed Description Prostate cancer is currently the fifth leading cause of cancer deaths among men globally, with 1 million diagnosed per year and mortality burden of over 300,000 deaths. The hypothesis of study is addition of apalutamide to RT+ LHRHa provides superior efficacy in terms of PSMA-PET metastatic progression-free survival-ppMPFS. Apalutamide is a non-steroidal androgen receptor (AR) antagonist being developed for the treatment of prostate cancer. RT+LHRHa is a combination therapy, when administered concomitantly, in high-risk patients with BCR relapsing after RP, potentially leads to relevant delay in the metastatic progression of prostate cancer at an early stage of the disease, or even cure in some cases. Study consists of 2 cohorts (intervention and observational cohort). At screening, eligible participants will undergo prostate-specific membrane antigen-positron emission tomography (PSMA-PET), whole-body Tc-bone scan, computed tomography (CT). Interventional Cohort, consisting of PSMA-PET positive participants, will undergoes 3 phases: Treatment Phase, a Post-treatment Phase and a Post-PSMA-PET Progression Phase. After 6-month Treatment Phase, participants will be prospectively assessed in Post-treatment Phase until PSMA-PET-positive metastatic progression is confirmed. Observational cohort will run parallelly to interventional cohort. PSMA-PET negative, participants will be observed until time-point when number of events required for analysis of primary endpoint is reached in Interventional Cohort. This cohort provides an approach to document the selection of treatments and observation of interventions in a real-life clinical practice setting. The duration of the study is estimated to be approximately 7 years.

Intervention  ICMJE
  • Radiation: Radiotherapy
    Participants will receive radiotherapy (RT) with or without optional stereotactic body radiation therapy (SBRT), which will start within 4 weeks after randomization.
  • Drug: LHRHa
    Participants will be administered with LHRHa (example, leuprolide, goserelin, triptorelin acetate) as a 3-monthly depot preparation within 3 days after randomization and the end of Week 12 or as a 6-monthly depot preparation within 3 days after randomization.

Study Arms  ICMJE
  • Active Comparator: Interventional Cohort (Group 1): RT+ LHRHa
    Participants who are PSMA-PET-positive will receive radiotherapy (RT) which is defined as prostate-bed plus pelvic lymph node salvage external-beam radiotherapy with or without optional stereotactic body radiation therapy (SBRT), along with a luteinizing hormone-releasing hormone agonist (LHRHa) as a 3-monthly depot preparation within 3 days after randomization and the end of Week 12, or as a 6-monthly depot preparation within 3 days after randomization.
    Interventions:
    • Radiation: Radiotherapy
    • Drug: LHRHa
  • Experimental: Interventional Cohort (Group 2): RT+LHRHa + Apalutamide
    Participants who are PSMA-PET-positive receive prostate-bed plus pelvic lymph node salvage external-beam radiotherapy (RT) with or without optional stereotactic body radiation therapy (SBRT), along with a LHRHa as a 3-monthly depot preparation within 3 days after randomization and the end of Week 12, or as a 6-monthly depot preparation within 3 days after randomization. Participants will also receive 240 milligram (mg) of apalutamide starting within 3 days after randomization as film-coated tablets, to be swallowed whole and together once daily with or without food, for a period of 180 Days.
    Interventions:
    • Radiation: Radiotherapy
    • Drug: LHRHa
    • Drug: Apalutamide
  • No Intervention: Observational Cohort(Group3) PSMA-PET Negative Participants
    Participants who are PSMA-PET-negative at screening, will be enrolled in the Observational Cohort. Data collected in the course of routine clinical practice during this period will include clinical evaluations, disease progression, therapies administered as per standard-of-care at the study-sites and survival status. For Observational Cohort, information will be entered into the electronic case report form (eCRF) from the medical records at least twice a year.
