Assessment of Cardiovascular Events Caused by New-Generation Androgen Receptor Pathway Inhibitors Used for Prostate Cancer: A Real-World Study in Japan.

Introduction: Androgen receptor pathway inhibitors (ARPIs) that significantly improve the prognosis of patients with prostate cancer include abiraterone acetate (androgen synthesis inhibitor) and enzalutamide (androgen receptor inhibitor). A recent analysis of ARPI and cardiovascular events using the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) has been reported; however, the evidence on cardiovascular events for abiraterone acetate and enzalutamide in real-world clinical practice is insufficient. Using a large Japanese database of medical institutions, the Japanese Medical Data Center (JMDC) medical institution database (JMDC Inc.
