Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	These shares represent restricted stock units and will be settled into common stock upon vesting. Each restricted stock unit would be converted into one share of FMTX common stock.
(2)	RA Capital Management, L.P. (the "Adviser") is the investment manager for RA Capital Healthcare Fund, L.P. (the "Fund") and RA Capital Nexus Fund, L.P. (the "Nexus Fund"). 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, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of any of the reported securities, except to the extent of their pecuniary interest therein.
(3)	Under Dr. Kolchinsky's arrangement with the Adviser, Dr. Kolchinsky holds the option and restricted stock units for the benefit of the Fund and the Nexus Fund. Dr. Kolchinsky is obligated to turn over to the Adviser any net cash or stock received upon sale of the common stock underlying the option and restricted stock units, which will offset advisory fees owed by the Fund and the Nexus Fund to the Adviser. The Reporting Persons therefore disclaim beneficial ownership of the option and restricted stock units and respective underlying common stock except to the extent of their pecuniary interest.
(4)	Held by the Fund.
(5)	Held by the Nexus Fund.
(6)	This option shall vest and become exercisable in full upon the earlier to occur of (i) June 8, 2023 and (ii) the next annual meeting of the Issuer's stockholders.
Remarks: Dr. Peter Kolchinsky, a Managing Partner of the Adviser, serves on the Issuer's board of directors.
