A Study of Adding Apalutamide to Radiotherapy and LHRH Agonist in High-Risk Patients With Hormone-Sensitive Prostate Cancer

Plain-language 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.

Inclusion Criteria:
* Histologically confirmed adenocarcinoma of the prostate
* Previously treated with radical prostatectomy with or without lymph node dissection and either: a) for biochemical recurrence after radical prostatectomy (RP): any post-operative prostate-specific antigen (PSA) measurement of less than (\<) 0.1 nanogram/milliliter (ng/mL) within 12 months after RP and without any PSA greater than and equal to (\>=) 0.1 ng/mL within the 4 to 8-week period after RP or b) for persistent PSA after RP: PSA \>=0.1 ng/mL within the 4 to 8-week period after RP, confirmed by additional measurement at least 3 weeks later
* Be able to swallow whole the study drug tablets or follow the instructions for admixing with apple sauce
* Results of the Prostate specific membrane antigen-positron emission tomography (PSMA-PET) at screening as determined by blinded independent, central review (BICR), must be: PSMA-PET-negative for any prostate cancer lesions (that is, no loco-regional lesion and no distant lesions); or PSMA-PET-positive for at least one loco-regional (pelvic) lesion without distant extra-pelvic lesion; or PSMA PET- positive for at least one loco--regional (pelvic) lesion with extra-pelvic lesion(s).
* High risk of developing metastasis defined as; a) for biochemical recurrence after RP: pathological Gleason score greater than or equal to (\>=) 8 evaluated from prostate tissue specimen at radical prostatectomy, or prostate-specific antigen doubling time (PSADT) less th…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
