Summary

This trial is testing if treatment with medications that reduce the male hormone level can shrink prostate cancer and reduce the chances of the cancer coming back. The treatments include a hormone injection and the study drugs, which include abiraterone acetate, prednisone, and apalutamide.

Who is the study for?
Men over 18 with advanced prostate cancer, who can consent and have adequate organ function. They must not have other active cancers or major health issues that could interfere with the trial, no prior treatments for prostate cancer (with some exceptions), and agree to use effective contraception.
What is being tested?
The study tests if hormone reduction drugs before surgery can shrink prostate cancer effectively. It combines monthly hormone injections, abiraterone acetate, prednisone, apalutamide with surgery and possibly radiotherapy to see if this approach is more successful in eliminating cancer.
What are the potential side effects?
Possible side effects include hormonal changes leading to hot flashes or sexual dysfunction, fatigue from anemia due to bone marrow suppression, liver function alterations from medication toxicity, potential digestive disturbances from pills taken orally.
