abiraterone and R-223 combination

Stéphane Oudard, Pablo Maroto, Gaston Demonty, Winald R Gerritsen
CONTEXT: Recent developments in the treatment of metastatic castration-resistant prostate cancer (mCRPC) have led to uncertainty about the optimal sequence of agents. OBJECTIVE: To review and assess treatment options and sequence in patients with mCRPC. EVIDENCE ACQUISITION: To identify data on the optimal use of approved treatments, we searched PubMed for studies on the use of recently approved agents for men with mCRPC published before March 2015...

CONTEXT: Radium-223 is an □ -particle transmitter with specific action on bone metastases. The Alpharadin in Symptomatic Prostate Cancer Patients (ALSYMPCA) study showed that radium-223 extended overall survival and delayed the onset of bone events in patients with symptomatic castration-resistant prostate cancer with bone metastases (mCRPC) and without visceral metastases, with a good safety profile. OBJECTIVE: To review the new scientific evidence on radium-223 based on prespecified and post-hoc analyses of the ALSYMPCA study and on early-access programs after the publication of the ALSYMPCA study, thereby providing new data on the management of patients with mCRPC...

Docetaxel based chemotherapy showed survival benefit and emerged as the mainstay of treatment for castration resistant prostate cancer (CRPC) in 2004. However, therapeutic options have expanded rapidly since 2011. The spectrum of new agents is broad and includes drugs that target the androgen axis (enzalutamide, abiraterone), immunotherapy (sipuleucel-T), bone seeking radionuclides (radium-223), and second line chemotherapy (cabazitaxel). In addition, new agents have been developed to reduce skeletal related events (denosumab)...

Treatment options have significantly expanded in recent years for men with metastatic castration-resistant prostate cancer (mCRPC), with the routine use of immunotherapy (sipuleucel-T) and novel hormonal agents such as enzalutamide and abiraterone acetate prior to taxane-based chemotherapy or radium-223 radiotherapy. A number of immune checkpoints limit the immune response of the host to metastatic tumor progression in prostate cancer, one of which is an immunosuppressive and pro-angiogenic cell called the myeloid-derived suppressor cell (MDSC)...

Metastatic castrate-resistant prostate cancer (CRPC) refers to the disease state in which metastatic prostate cancer fails to respond to androgen deprivation therapy (ADT). This can be manifest as a rising PSA, increase in radiographically measurable disease, or progression of clinical disease. Roughly 90 % of men with metastatic prostate cancer have bone metastases, which is a predictor of both morbidity and mortality. Historically, treatment has been palliative, consisting of external beam radiation therapy (EBRT) and pharmacological analgesics for pain control and osteoclast inhibitors, such as bisphosphonates and denosumab to mitigate skeletal-related events...

PURPOSE: To provide treatment recommendations for men with metastatic castration-resistant prostate cancer (CRPC). METHODS: The American Society of Clinical Oncology and Cancer Care Ontario convened an expert panel to develop evidence-based recommendations informed by a systematic review of the literature. RESULTS: When added to androgen deprivation, therapies demonstrating improved survival, improved quality of life (QOL), and favorable benefit-harm balance include abiraterone acetate/prednisone, enzalutamide, and radium-223 ((223)Ra; for men with predominantly bone metastases)...

The drug treatment of prostate cancer was for many years based on androgen deprivation with luteinizing hormone-releasing hormone (LHRH) analogues.This treatment still represents the standard first line treatment for advanced prostate cancer. In cases of progression to metastatic castration-resistant prostate cancer (mCRPC) further treatment options used to be limited. Only the chemotherapy drug docetaxel could demonstrate a significant overall survival benefit. Within the last few years, however, five new treatments for patients with mCRCP have achieved significant results in large phase III trials...
