Explanation of Responses:

Id Content
F1 Represents the grant of a stock option to Zachary Scheiner pursuant to the Issuer's Outside Director Compensation Policy (the "Policy"). One hundred percent (100%) of the shares subject to the option shall vest on June 11, 2026, subject to Dr. Scheiner's continuing to be an Outside Director (as defined in the Policy) through such applicable date.
F2 RA Capital Management, L.P. (the "Adviser") is the investment manager for RA Capital Healthcare Fund, L.P. (the "Fund"), RA Capital Nexus Fund II, L.P. (the "Nexus Fund II"), and a separately managed account (the "Account"). The general partner of the Adviser is RA Capital Management GP, LLC (the "Adviser GP"), of which Dr. Peter Kolchinsky and Mr. Rajeev Shah are the managing members. The Adviser, the Adviser GP, the Fund, the Nexus Fund II, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of any of the reported securities, except to the extent of its or his pecuniary interest therein.
F3 Under Dr. Scheiner's arrangement with the Adviser, Dr. Scheiner holds the option for the benefit of the Fund, the Nexus Fund II and the Account. Dr. Scheiner is obligated to turn over to the Adviser any net cash or stock received upon exercise of the option, which will offset advisory fees owed by the Fund, the Nexus Fund II and the Account to the Adviser. The Reporting Persons therefore disclaim beneficial ownership of the option and underlying common stock.

Remarks:

Dr. Zachary Scheiner, a Principal of RA Capital Management, L.P., serves on the Issuer's board of directors.
