This Amendment No. 4 (“Amendment No. 4”) amends the initial statement on Schedule 13D first filed by Clarus Lifesciences III, L.P. and certain other reporting persons on January 26, 2016, as amended by Amendment No. 1 thereto on June 19, 2018, Amendment No. 2 thereto on January 11, 2019 and Amendment No. 3 thereto on September 6, 2019 (collectively, the “Schedule 13D”), with respect to the Common Shares, without par value (the “Shares”), of ESSA Pharma Inc., a British Columbia corporation (the “Issuer”).

Certain terms used but not defined in this Amendment No. 4 have the meanings assigned thereto in the Schedule 13D. Except as specifically provided herein, this Amendment No. 4 does not modify any of the information previously reported in the Schedule 13D.

Item 2. Identity and Background.

Item 2 of the Schedule 13D is hereby amended by incorporating herein by reference the information set forth on the updated Schedule I attached hereto.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) Clarus Lifesciences III, L.P. (the “Fund”) beneficially owns 2,109,164 Shares, consisting of 2,003,103 Shares and Warrants exercisable for 106,061 Shares and an investment fund affiliated with the Fund beneficially owns 78,748 Shares, received in the Fund Distribution described in Item 5(c) below.

Clarus Ventures III GP, L.P. (“Clarus GP”) is the sole general partner of the Fund. Blackstone Clarus III L.L.C. is the sole general partner of Clarus GP. Blackstone Holdings II L.P. is the sole member of Blackstone Clarus III L.L.C. and indirectly controls the general partner of the investment fund referred to above. The general partner of Blackstone Holdings II L.P. is Blackstone Holdings I/II GP L.L.C. The sole member of Blackstone Holdings I/II GP L.L.C. is Blackstone Inc. The sole holder of the Series II preferred stock of Blackstone Inc. is Blackstone Group Management L.L.C. Blackstone Group Management L.L.C. is wholly-owned by Blackstone’s senior managing directors and controlled by its founder, Stephen A. Schwarzman.

Each such Reporting Person may be deemed to beneficially own the Shares reported herein, but neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person (other than the direct holder thereof) is the beneficial owner of the Shares referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or for any other purpose, and each of the Reporting Persons expressly disclaims beneficial ownership of such Common Stock.

The percentage of outstanding Shares of the Issuer which may be deemed to be beneficially owned by each Reporting Person is set forth on Line 13 of such Reporting Person’s cover sheet and was calculated based on (i) the 43,984,346 Shares outstanding as of November 18, 2021, as set forth in the Annual Report on Form 10-K filed by the Issuer on November 18, 2021, plus (ii) the 106,061 Shares issuable upon exercise of the Warrants held by the Fund.

(b) Regarding the number of shares as to which such person has:

(i) sole power to vote or to direct the vote: See line 7 of cover sheets

(ii) shared power to vote or to direct the vote: See line 8 of cover sheets

(iii) sole power to dispose or to direct the disposition: See line 9 of cover sheets

(iv) shared power to dispose or to direct the disposition: See line 10 of cover sheets

(c) On January 10, 2022, the Fund distributed 1,300,000 Shares to its partners, including Clarus GP (the “Fund Distribution”) and an investment fund affiliated with the Fund, which received 78,748 of the Shares. Clarus GP then distributed the 326,167 Shares it received in the Fund Distribution to its limited partners. Except as set forth above, none of the Reporting Persons has effected any transaction in the Shares during the last 60 days.

(e) As of January 10, 2022, following the distributions described herein, the Reporting Persons ceased to be the beneficial owners of more than five percent of the outstanding Shares.
