About ESSA Pharma Inc.

ESSA Pharma Inc. is a development-stage pharmaceutical company focused on a proprietary small molecule compound named EPI-506 as a treatment for advanced prostate cancer. EPI-506 was designed to block a novel target on the androgen receptor, the N-terminal domain. Inhibition of the N-terminal domain of the androgen receptor has the potential to block tumor growth after current hormone-therapy drugs have failed.  That potential has been demonstrated by ESSA in several well-accepted in vitro and in vivo studies showing that EPI-506 inhibits tumor growth in those models.  The target patient population for EPI-506 – metastatic castration resistant prostate cancer patients who have failed current hormone therapies – represents the greatest unmet medical need in this therapeutic area. Prostate cancer patients eventually fail current hormone therapies.  In its upcoming Phase 1/2 clinical trial, ESSA intends to demonstrate the effectiveness of EPI-506 in treating prostate cancer patients who have failed abiraterone or enzalutamide, the current standard-of-care drugs in prostate cancer treatment.  ESSA is currently preparing to file an Investigational New Drug application with the U.S. Food and Drug Administration at the end of Q1 or early Q2 2015, to enable dosing of patients mid-2015. 

About Prostate Cancer

Prostate cancer is the second most commonly diagnosed cancer among men and the fifth most common cause of male cancer death worldwide (Globocan, 2012).  Adenocarcinoma of the prostate is dependent on androgen for tumor progression. Prostate cancer growth is dependent on androgens, and depleting or blocking androgen action has been a mainstay of hormonal treatment for over 6 decades.  Although tumors are often initially sensitive to medical or surgical therapies that decrease levels of testosterone (i.e., ADT), disease progression despite castrate levels of testosterone generally represents a transition to the lethal variant of the disease (mCRPC) and most patients ultimately succumb to the illness. The treatment of mCRPC patients has evolved rapidly over the past 5 years; despite these advances, additional treatment options are needed to improve clinical outcomes in patients, particularly those who fail existing treatments including Abiraterone or Enzalutamide or those that have contraindications to receive those drugs. Over time, patients with mCRPC generally experience continued disease progression, worsening pain, leading to substantial morbidity and limited survival rates.  ESSA's novel approach to blocking the androgen pathway has been shown to be effective in blocking tumor growth when current therapies are no longer effective.
