Effective as of January 9, 2023, the ratio of our ADSs to ordinary shares changed from one (1) ADS representing thirty (30) ordinary shares to a new ratio of one (1) ADS representing three hundred (300) ordinary shares, which ratio change had the same effect as a one-for-ten reverse ADS split, or the ADS Ratio Change.

This Supplement is being filed to disclose the following:


On November 21, 2023, the Company entered into an inducement offer letter agreement, or the Inducement Letter, with a certain holder, or the Holder, of certain of the Company’s existing warrants to purchase up to (i) 1,363,637 of the Company’s ADSs comprising the Series A warrants included in the January 2023 Warrants at an exercise price of $6.00 per ADS, or the January 2023 Series A Warrants, and (ii) 600,000 of the Company’s ADSs issued on December 23, 2021 at an exercise price of $5.50 per ADS, or the December 2021 Warrants and together with the January 2023 Series A Warrants, the Existing Warrants.


Pursuant to the Inducement Letter, the Holder agreed to exercise for cash its Existing Warrants to purchase an aggregate of 1,963,637 of the Company’s ADSs at a reduced exercise price of $1.53 per ADS in consideration of the Company’s agreement to issue new warrants to purchase ADSs, or the New Warrants to purchase up to an aggregate of 3,927,274 ADSs, or the New Warrant Shares, at an exercise price of $1.75 per ADS. The Company expects to receive aggregate gross proceeds of approximately $3.0 million from the exercise of the Existing Warrants by the Holder, before deducting placement agent fees and other offering expenses payable by the Company. In addition, the Company has agreed to reduce the exercise price of Series B warrants to purchase 1,363,637 ADSs issued in the January 2023 and held by the Holder from $5.50 per ADS to $1.75 per ADS and extend the term of such Series B warrants to twenty months from the Closing Date, as defined below.


The Company has also agreed to issue to H.C. Wainwright & Co., LLC, or the Placement Agent, or its designees warrants, or the Placement Agent Warrants, to purchase up to 137,455 ADSs (representing 7.0% of the Existing Warrants being exercised) which will have the same terms as the New Warrants except the Placement Agent Warrants will have an exercise price equal to $1.9125 per share (125% of the reduced exercise price of the Existing Warrants). Similar to the New Warrants, the Placement Agent Warrants will be immediately exercisable from the date of issuance until the five year anniversary of such date.


The closing of the transactions contemplated pursuant to the Inducement Letter is expected to occur on or about November 24, 2023, or the Closing Date, subject to satisfaction of customary closing conditions. The Company expects to use the net proceeds from these transactions for funding research and development and clinical trials and for other working capital and general corporate purposes.


No changes have been made to the other warrants issued in the January 2023 Offerings, which shares may be resold under the Prospectus, as amended by this Supplement.
