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.

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.
