Is this trial a fit for you?

Likely a good fit

Ideal candidates are men aged 55 or older with advanced prostate cancer who have at least two prescriptions for enzalutamide or darolutamide and a documented mHSPC or nmCRPC diagnosis.

Probably not a fit

Patients who do not experience cardiovascular events or who do not use ARPI therapies may see limited benefit from the study.

What this trial studies

This is an observational study that compares the frequency of serious heart-related events among older men with advanced prostate cancer who are treated with two approved anti-androgen medications. Participants are men aged 55 and older with metastatic hormone-sensitive or non-metastatic castration-resistant disease who have evidence of ARPI treatment with enzalutamide or darolutamide. The study uses existing prescription and medical data to identify outcomes without assigning any treatments. No intervention is performed as part of the study. The goal is to see if one medication is associated with more cardiovascular events than the other and to identify patient factors that may influence risk.

Why it matters

Potential benefit: If successful, the study could clarify cardiovascular safety differences between enzalutamide and darolutamide for older men with advanced prostate cancer.

How similar studies have gone: Other observational analyses have explored cardiovascular safety with ARPI therapies, but direct head-to-head comparisons in this specific older male population remain limited.
