This prospectus supplement supplements the prospectus dated March 17, 2023 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-268603) for which Post-Effective Amendment No. 1 was filed with the Securities and Exchange Commission on March 14, 2023 and declared effective by the Securities and Exchange Commission on March 17, 2023. This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Amendment No. 1 to the Current Report on Form 8-K/A, filed with the Securities and Exchange Commission on September 27, 2023 (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.

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.
