Abiraterone With Different Steroid Regimens for Side Effect Related to Mineralcorticoid Excess Prevention in Prostate Cancer Prior to Chemotherapy

• Status: Completed
• Trial end date: 2018-06-05
• Target enrollment: 0
• Participant gender: Male

Summary

The purpose of the study is to determine the safety and clinical benefit of the combinations of abiraterone acetate and prednisone or abiraterone and dexamethasone in prostate cancer patients. Prednisone will be given at one of three different dose schedules. Dexamethasone will be given at one dose schedule. This will include looking at what side effects occur and how often they occur. In addition the impact of the study drug on quality of life and pain will be evaluated. The study will also collect data on subsequent treatment of patients after they come off the study drug (approximately 4.5 years after the start of study treatment of the first subject participating in the study). By analyzing blood samples, the study aims to identify if some markers could help to understand if the treatment with abiraterone is effective and also help to understand if patients can become resistant.

Criteria

Inclusion Criteria:

Have a histologically or cytologically confirmed adenocarcinoma of the prostate Have metastatic disease documented by positive bone scan or by computed tomography or magnetic resonance imaging Have prostate cancer progression documented by prostate specific antigen according to Prostate Cancer Working Group 2 or radiographic progression according to modified RECIST (response evaluation criteria in solid tumors, v1.1) criteria Be asymptomatic from prostate cancer. A score of 0-1 on BPI-SF Question #3 (worst pain in last 24 hours) will be considered asymptomatic Be surgically or medically castrated, with testosterone levels of <50 ng/dL (<2.0 nmol/L). If the subject is being treated with luteinizing hormone releasing hormone (LHRH) agonists or antagonists (subjects who have not undergone orchiectomy), this therapy must have been initiated at least 4 weeks prior to Day 1, Cycle 1 and must be continued throughout the study.

Exclusion Criteria:

Has a history of pituitary or adrenal dysfunction Has an active infection or other medical condition that would contraindicate corticosteroid use Has any chronic medical condition requiring corticosteroid treatment or has received prior corticosteroid treatment for prostate cancer Has a pathological finding consistent with small cell carcinoma of the prostate Has a known brain metastasis
