OBJECTIVE In this Phase 2 multicenter study the efficacy and safety of oral abiraterone acetate (1000 mg/once daily) plus prednisolone (5 mg/twice daily) was evaluated in metastatic castration-resistant prostate cancer patients from Japan who had previously received docetaxel-based chemotherapy. METHODS Men (aged ≥20 years) with metastatic castration-resistant prostate cancer (prostate-specif...

The advent of exponential growth of novel agents tested and approved for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) has brought about a need for understanding of the mechanism of action, side-effects, and clinical efficacy of these drugs as they relate to these patients. This review will provide a synopsis of the treatment landscape in mCRPC as varyin...

The approval or clinical evaluation of several new agents - cabazitaxel, abiraterone acetate, enzalutamide, sipuleucel-T, and radium-223 - has significantly changed the management of patients with metastatic castration-resistant prostate cancer (mCRPC) prior to or after docetaxel-based chemotherapy. All of these agents have resulted in a significant survival benefit as compared to their control...

BACKGROUND Abiraterone Acetate (AA) and Enzalutamide (Enz) are effective hormonal treatments in mCRPC patients. Retrospective studies suggested clinical cross-resistance between Enz and AA. However, 12.8-39.1% of patients previously treated with docetaxel (Doc) and AA do respond to Enz. These responders have not been characterized. METHODS 102 Enz treated mCRPC patients after AA and Doc treat...

BACKGROUND Abiraterone acetate (AA), a selective inhibitor of the CYP17 enzyme, demonstrated a significant improvement in the treatment of patients with metastatic castration-resistant prostate cancer. The risk of endocrine side effects, mainly an increased adrenal mineralocorticoid production, could limit its use in patients with atrial fibrillation. METHODS We retrospectively reviewed the c...

While androgen-deprivation therapy can induce dramatic clinical responses in advanced and metastatic prostate cancer, refractory disease (castration-resistant prostate cancer [CRPC]) eventually emerges. In recent years, several studies have demonstrated the importance of residual intratumoral androgens in maintaining androgen receptor (AR) transcriptional activity in CRPC. The cytochrome P450 e...

Rapid progress was recently made in the treatment of prostate cancer, especially metastatic castration-resistant prostate cancer. At the NCCN 18th Annual Conference, Dr. Philip W. Kantoff reviewed the data supporting the use of abiraterone acetate, enzalutamide, cabazitaxel, sipuleucel-T, and radium-223 (pending approval), and offered recommendations for their sequential use in different settin...

The treatment landscape for men with castration-resistant prostate cancer (CRPC) is undergoing significant changes; a redefinition of the respective roles of oncologists and urologists will probably occur. In addition, the advent of the multidisciplinary team or coordinated-care approach, which has been gathering momentum over the last decade, will become not simply a preference but a clear nec...

BACKGROUND Previous studies have demonstrated an association between prostate-specific antigen (PSA) kinetics and predictive value for treatment outcomes. Abiraterone acetate (AA) is a newly approved cytochrome-P450C17 inhibitor for treatment of metastatic castration-resistant prostate cancer (mCRPC), and few studies have evaluated PSA kinetics using AA so far. Results of a study evaluating PSA...

Androgens play a prominent role in the development, maintenance and progression of prostate cancer. The introduction of androgen deprivation therapies into the treatment paradigm for prostate cancer patients has resulted in a wide variety of benefits ranging from a survival advantage for those with clinically localized or locally advanced disease, to improvements in symptom control for patients...
