("ESSA" or the "Company") (((TSX-V: EPI, NASDAQ:EPIX), a pharmaceutical company focused on developing novel therapies for the treatment of prostate cancer, today provided a corporate update and reported financial results for the fiscal second quarter ended March 31, 2018. All references to "$" in this release refer to United States dollars, unless otherwise indicated. 

"Following the successful close of our $26 million financing in early 2018, we have made significant advances toward our clinical objective of developing more potent next-generation aniten compounds," said President and CEO, David R. Parkinson.  "We expect to nominate a next-generation clinical candidate in 2018, and to file an Investigational Drug Application in the first half of calendar 2019."

Corporate Update

• Further enhanced in vitro potency and reduced metabolism in order to select a potential clinical candidate.
  
  
• Generated compounds with significant improvements in both potency and stability as compared to first-generation aniten N-terminal domain inhibitor compound, EPI-506.
  
• Completed $26 million financing to fund preclinical and clinical development within next-generation aniten program.
  
  
• Regained compliance with the Nasdaq Captial Market's (the "Nasdaq's") minimum bid price requirement and the Company is now in compliance with all applicable listing standards and ESSA's common stock will continue to be listed on the Nasdaq.
  
  
• Appointed a representative of investor Omega Funds, a life sciences-focused venture capital firm, to the Company's board of directors.
  
  
• Hired senior professionals in the areas of preclinical drug development, chemistry, manufacturing, and control.

Summary Financial Results
Effective April 25, 2018, the Company consolidated its issued and outstanding common shares on the basis of one post-consolidation share for every 20 pre-consolidation shares. The consolidation applied to all ESSA common shares, prepaid warrants, and other securities convertible into or exercisable for common shares.  Unless otherwise stated, all ESSA common share and per share amounts have been restated retrospectively to reflect this share consolidation.

• Net Income (Loss). ESSA recorded a net loss of $4.4 million ($0.83 loss per common share based on 5,287,608 weighted average common shares outstanding) for the quarter ended March 31, 2018, compared to a net loss of $7.6 million ($0.15 loss per common share based on 1,454,844 weighted average common shares outstanding) for the quarter ended March 31, 2017.
  
  
• Research and Development ("R&D") expenditures. R&D expenditures for the quarter ended March 31, 2018, were $2.0 million (net of grants and gross), compared to $2.5 million net of grants ($3.7 million gross) for the quarter ended March 31, 2017. For the quarter ended March 31, 2018, decreases in R&D expenditures were primarily related to decreases in manufacturing and clinical trial costs as the Company had concluded its Phase I clinical study of EPI-506 in September 2017, compared to the quarter ended March 31, 2017, during which ESSA was conducting the EPI-506 clinical trial and incurring associated development costs. The EPI-506 clinical trial commenced in November 2015.
  
  
• General and administration ("G&A") expenditures. G&A expenditures for the quarter ended March 31, 2018, were $2.2 million, compared to $1.4 million for the quarter ended March 31, 2017. This increase primarily reflected increased corporate activity, as well as compensation expenses and increased share-based payments reflecting stock option grants in the quarter.

Liquidity and Outstanding Share Capital
Cash on hand at March 31, 2018, was $21.7 million, with working capital of $17.9 million, reflecting the aggregate gross proceeds of the financing, totaling $26 million, completed in January 2018.

As of March 31, 2018, the Company had 5,776,098 common shares issued and outstanding, and 2,189,000 common shares issuable on the exercise of prepaid warrants at $0.002.  If all prepaid warrants are exercised, there would be approximately 7,965,098 ESSA common shares outstanding.

In addition, there were 474,938 common shares issuable upon the exercise of warrants and broker warrants at a weighted-average exercise price of $34.35 per ESSA common share and 858,461 ESSA common shares issuable upon the exercise of outstanding stock options at a weighted-average exercise price of $5.47 per common share.

About ESSA Pharma Inc.
ESSA is a pharmaceutical company focused on developing novel and proprietary therapies for the treatment of castration-resistant prostate cancer ("CRPC") in patients whose disease is progressing despite treatment with current therapies. ESSA believes that its proprietary compounds can significantly expand the interval of time in which patients suffering from CRPC can benefit from hormone-based therapies, by disrupting the androgen receptor ("AR") signaling pathway that drives prostate cancer growth and by preventing AR transcriptional activity by binding selectively to the N-terminal domain ("NTD") of the AR. A functional NTD is essential for transactivation of the AR. In preclinical studies, blocking the NTD has demonstrated the capability to overcome the known AR-dependent mechanisms of CRPC. ESSA was founded in 2009.

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 and depleting or blocking androgen action has been a mainstay of hormonal treatment for over six decades. Although tumors are often initially sensitive to medical or surgical therapies that decrease levels of testosterone, disease progression despite castrate levels of testosterone generally represents a transition to the lethal variant of the disease, metastatic CPRC ("mCRPC"), and most patients ultimately succumb to the illness. The treatment of mCRPC patients has evolved rapidly over the past five 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 who 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. In both in vitro and in vivo animal studies, 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.
