#### Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On February 10, 2023, Sigilon Therapeutics, Inc. (the "Company") terminated the employment of May Orfali, M.D., the Company's Chief Medical Officer, effective as of such date. Consistent with the benefits provided under the Company's Amended and Restated Severance and Change in Control Policy in connection with a Qualifying Termination (as such term is defined in that policy), and in exchange for a release of claims and other customary separation agreement terms, the Company anticipates that Dr. Orfali will continue to receive her current base salary for a period of nine months (the "Severance Period"). Dr. Orfali may elect to continue her group healthcare benefits, to the extent authorized by and consistent with COBRA. If elected, the Company would pay an amount equal to the monthly employer contribution until the earlier of (i) the end of the Severance Period or (ii) the date Dr. Orfali becomes eligible for insurance through another employer or otherwise becomes ineligible for COBRA. Dr. Orfali remains eligible to receive an annual bonus for the Company's 2022 fiscal year, the amount of which will be determined by the Company's Board of Directors in its sole discretion, based on the achievement of specific milestones or performance criteria established by the Board of Directors for such fiscal year. In addition, the Company expects that Dr. Orfali will provide consulting services to the Company for a period of at least three months at a mutually agreed upon hourly rate.

#### SIGNATURES
Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
