This prospectus supplement supplements the prospectus dated March 29, 2024 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-268603) for which Post-Effective Amendment No. 2 was filed with the Securities and Exchange Commission on March 27, 2024 and declared effective by the Securities and Exchange Commission on March 29, 2024. This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K, filed with the Securities and Exchange Commission on October 7, 2024 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus and this prospectus supplement relate to the issuance by us of up to an aggregate of 11,003,988 shares of our common stock, par value $0.0001 per share (“Common Stock”), issuable upon the exercise of (i) 4,104,000 private placement warrants (the “Private Warrant Shares”) originally sold in a private placement at a price of $0.75 per warrant in connection with the initial public offering of Vickers Vantage Corp. I (“Vickers”) (and a portion of which were subsequently transferred to Sorrento Therapeutics, Inc. (“Sorrento”) at no cost in connection with the Business Combination (as defined below)) (the “Private Warrants”) and (ii) 6,899,988 public warrants (the “Public Warrant Shares”) originally sold to the public investors in connection with the initial public offering of units of Vickers (the “Public Warrants” and together with the Private Warrants, the “Warrants”) at a price of $10.00 per unit, with each unit consisting of one ordinary share of Vickers and one-half of one warrant to purchase one ordinary share of Vickers. As previously disclosed in prospectus supplement no. 16 to the Prospectus, filed with the Securities and Exchange Commission on October 6, 2023, Sorrento subsequently sold (a) 60,068,585 shares of Common Stock; (b) 29,057,097 shares of Series A Preferred Stock; and (c) warrants exercisable for 4,490,617 shares of Common Stock, in each case to us by delivery of such purchased securities to SCLX Stock Acquisition JV LLC, a Texas limited liability company (“SCLX JV”) and our indirect wholly-owned subsidiary, of which warrants exercisable for 4,000,000 shares of Common Stock were subsequently transferred by SCLX JV to Oramed Pharmaceuticals, Inc., a Delaware corporation (“Oramed”).

Each Warrant entitles the holder thereof to purchase one share of our Common Stock at a price of $11.50 per share. We will not receive the proceeds from the resale of the Private Warrant Shares or the Public Warrant Shares hereunder; however, we will receive the proceeds from any exercise of the Private Warrants and the Public Warrants.

The Prospectus and this prospectus supplement also relates to the offer and sale from time to time by:

(a) the selling stockholders named in this prospectus (including their permitted transferees, donees, pledgees and other successors-in-interest) (collectively, the “Selling Stockholders”) of up to an aggregate of 71,459,469 shares (the “Resale Shares”) of our Common Stock, consisting of:

(i) up to 3,983,057 shares of Common Stock (the “Sponsor Shares”) held by Vickers Venture Fund VI Pte Ltd, Vickers Venture Fund VI (Plan) Pte Ltd, Pei Wei Woo, Suneel Kaji and Steve Myint (collectively, the “Sponsors”), comprised of 3,450,000 shares that were issued on November 9, 2022 upon conversion of the same number of our former ordinary shares (initially acquired by the Sponsors prior to the initial public offering of units of Vickers Vantage Corp. I at a purchase price of $0.007 per ordinary share) in connection with the Domestication and the Business Combination (each as defined below) and 533,057 shares that were also issued on November 9, 2022 upon the contribution of certain indebtedness by Vickers Venture Fund VI Pte Ltd and Vickers Venture Fund VI (Plan) Pte Ltd at a contribution value of $10.00 per share, in connection with the Business Combination pursuant to a debt contribution agreement;

(ii) up to 61,985,795 shares of Common Stock (the “Merger Shares”) issued to Sorrento on November 10, 2022 in connection with the Business Combination at an equity consideration value of $10.00 per share, of which 60,068,585 are now held by SCLX JV;

(iii) up to 4,104,000 Private Warrant Shares issuable to certain Selling Securityholders upon the exercise of the Private Warrants at an exercise price of $11.50 per share; and

(iv) up to 1,386,617 Public Warrant Shares issuable to certain Selling Securityholders upon the exercise of the Public Warrants at an exercise price of $11.50 per share; and

(b) the selling warrantholders named in this prospectus (including their permitted transferees, donees, pledgees and other successors-in-interest) (collectively, the “Selling Warrantholders” and, together with the Selling Stockholders, the “Selling Securityholders”) of up to 4,104,000 Private Warrants (which were originally issued at a price of $0.75 per Private Warrant, of which 3,104,000 were transferred from the Sponsors to Sorrento at no cost in connection with the Business Combination), and 1,386,617 Public Warrants (which were acquired by Sorrento in open-market purchases at a weighted average purchase price of $0.3078 per Public Warrant). Sorrento subsequently transferred 4,490,617 warrants held by it to SCLX JV, of which 4,000,000 warrants were subsequently transferred by SCLX JV to Oramed and then subsequently repurchased by us from Oramed.
