Neoadjuvant Therapy of Abiraterone Plus ADT for Intraductal Carcinoma of the Prostate

• Status: Not yet recruiting
• Trial end date: 2024-12-01
• Target enrollment: 0
• Participant gender: Male

Summary

Neoadjuvant treatment before radical prostatectomy has been proven to provide benefits on peri-operation results, especially on reduction of tumor volume and minimization of biochemical recurrence. This study will evaluate the efficacy and safety of abiraterone acetate Plus androgen deprivation therapy（ADT）in high-risk localized prostate cancer with intraductal carcinoma of the prostate（IDC-P）.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: West China Hospital
• Treatments: Abiraterone Acetate; Goserelin; Prednisolone
