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

Study 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.

What This Trial Means for Biotech Investors
Trial Phase Context

Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.

Status & Expected Data

Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.

Enrolled: 693 participants
