Explanation of Responses:

1. Subject to the terms and conditions set forth in the Pre-funded Warrant, the holder thereof may, at any time and from time to time on or after April 19, 2024, exercise the Pre-funded Warrant until it has been exercised in full. The Pre-funded Warrants reported herein contain an exercise limitation prohibiting the holder from exercising the Pre-Funded Warrants until such time as the holder, together with the Reporting Persons and certain other related parties, would not beneficially own after any such exercise more than 4.99% of the then issued and outstanding Common Stock (the "Blocker"). Due to the Blocker, the Pre-funded Warrants beneficially owned by the Reporting Persons are not presently exercisable.

2. The securities to which this filing relates are held directly by Lynx1 Master Fund LP to which Lynx1 Capital Management LP (the "Investment Manager") serves as investment manager. Weston Nichols ("Mr. Nichols") is the sole member of Lynx1 Capital Management GP LLC, the general partner of the Investment Manager. Each of the Investment Manager and Mr. Nichols disclaims beneficial ownership of the securities to which this filing relates for purposes of Section 16 of the Securities and Exchange Act of 1934, as amended, except to the extent of his or its pecuniary interest therein, if any.
