NCT ID NCT04577833

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at how the body absorbs different versions of two prostate cancer drugs, niraparib and abiraterone acetate, taken together with prednisone. It involves 136 men with metastatic castration-resistant prostate cancer. The goal is to compare the absorption of various tablet strengths and forms, not to test if the drugs work against the cancer.
