Explanation of Responses:

1. The securities are directly held by Perceptive Life Sciences Master Fund Ltd. (the "Master Fund"). Perceptive Advisors LLC (the "Advisor") serves as the investment manager of the Master Fund. The Advisor disclaims, for purposes of Section 16 of the Securities Exchange Act of 1934, beneficial ownership of such securities, except to the extent of its indirect pecuniary interest therein, and this report shall not be deemed an admission that the Advisor is the beneficial owner of such securities for purposes of Section 16 or for any other purposes. Joseph Edelman, the managing member of the Advisor, serves as a director of the Issuer and has filed a separate Form 3.

2. The Series B Preferred Stock is convertible into shares of the Issuer's Common Stock on a 1-for-1 basis, and will automatically convert to shares of the Issuer's Common Stock upon the closing of the Issuer's initial public offering. These shares have no expiration date.

3. One-thirty-sixth of the shares subject to the option will vest on October 17, 2020 and thereafter one-thirty-sixth of the shares subject to the option will vest each month.

4. Consists of options to purchase shares of the Issuer's common stock awarded to Mr. Edelman in connection with his role as a member of the Issuer's board of directors. The Advisor may be deemed to have an indirect pecuniary interest in the options to purchase common stock of the Issuer reported herein because the Advisor has the right to receive the director compensation provided in respect of Mr. Edelman's board service through a partial management fee offset. The Advisor disclaims, for purposes of Section 16 of the Securities Exchange Act of 1934, beneficial ownership of such securities, except to the extent of its indirect pecuniary interest therein, and this report shall not be deemed an admission that the Advisor is the beneficial owner of such securities for purposes of Section 16 or for any other purposes.
