The face of metastatic prostate cancer (PC) has been remarkably reshaped with the current advances in its management. Kudos to the cuttingedge research that has pinpointed new targets and agents. The main stumbling block in this disease is progression on androgen deprivation therapy (ADT) and the development of castrate resistance. Despite this phenomenon, the majority of patients with PC continue to rely on androgen receptors (ARs) for disease growth and progression. Several of these newer agents directly or indirectly target ARs. Many drugs have earned US Food and Drug Administration (FDA) approval in the past decade by showing survival benefit, which is the gold standard endpoint in all the pivotal PC trials. An array of new targets and agents are being explored currently. The future of metastatic castration-resistant prostate cancer (mCRPC) appears exciting with the expanding armamentarium; however, the challenges of affordability and sequencing of the agents remain.
