Neo-adjuvant Abiraterone + Luteinizing Hormone-Releasing Hormone (LHRH) Versus LHRH in Prostate Cancer

Status:
Completed

Trial end date:

Target enrollment:
0

Participant gender:
Male

Summary

The goal of this clinical research study is to find out how treatment with abiraterone acetate in combination with prednisone and a Luteinizing Hormone-Releasing Hormone (LHRH) analogue changes the tumor in comparison to treatment with an LHRH analogue alone. Objectives: Primary Objective: To assess the difference in pathologic stage < pT2 between Group A and Group B. Secondary Objective: - To assess and compare the changes in levels of androgens (pre, during, and post treatment) in the serum, primary tumor microenvironment and bone marrow between Group A and Group B. - To assess changes in biomarkers related to androgen signaling and other cancer-related pathways between Group A and Group B. - To assess the difference in rate of positive surgical margins between Group A and Group B. - To assess the safety profile of abiraterone acetate and low dose prednisone in a preoperative setting.

granulocyte count (ANC) > 1,500 and platelet count of > 100,000.

6. Normal pituitary and adrenal function

7. Patients should be deemed to be candidates for radical prostatectomy.

Exclusion Criteria:

adenocarcinoma); neuroendocrine tumor

uncontrolled infection

3. Uncontrolled hypertension

4. Abnormal Liver function

5. Active or symptomatic viral hepatitis or chronic liver disease

6. Clinically significant heart disease

7. Other active malignancy

8. History of gastrointestinal disorders (medical disorders or extensive surgery) which
may interfere with the absorption of the study drug

9. Previous treatment with abiraterone acetate

10. Patients who are not appropriate surgical candidates for radical prostatectomy

11. Prior chemotherapy or radiation therapy for prostate cancer.

12. Condition or situation which, in the investigator's opinion, may put the patient at
significant risk, may confound the study results, or may interfere significantly with
patient's participation in the study

Note: There are additional inclusion and exclusion criteria. The study center will
determine if you meet all of the criteria.
