CAMBRIDGE, Mass., August 6, 2020 – Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today reported business highlights and financial results for the second quarter of 2020.

“I am extremely proud of our recent progress, as we remain on track with previously shared guidance despite the unpredictable challenges presented by COVID-19,” said Cynthia Collins, Chief Executive Officer of Editas Medicine. “Our lead program evaluating EDIT-101 for the treatment of Leber congenital amaurosis 10 has continued to advance with dosing resuming in the Phase 1/2 BRILLIANCE trial, further solidifying Editas as the leader in the field of in vivo gene editing. Substantial progress has also been made toward an IND filing for EDIT-301 this year, with recent data presented at EHA providing preclinical proof-of-concept for this potentially best-in-class cell medicine for sickle cell disease.”

Ms. Collins continued, “Alongside the clinical and scientific advances made last quarter, we also executed on several corporate milestones to better position the Company as we expand our clinical-stage pipeline. To ensure the efficient advancement of our pioneering gene editing medicines, we strengthened our balance sheet with the closing of a common stock offering resulting in gross proceeds of approximately $216 million. Importantly, we also secured dedicated cGMP-compliant manufacturing space to facilitate the completion of IND-enabling studies and early stage clinical manufacturing for our engineered cell medicines including EDIT-301 for sickle cell disease and EDIT-201, an allogeneic NK cell medicine for solid tumors.”

Recent Achievements and Outlook

In Vivo CRISPR Medicines

· Ocular MedicinesRegained full control of ocular medicines

Editas Medicine (Company) has terminated its 2017 agreement with Allergan, now part of AbbVie, and entered a new agreement with AbbVie that returns development and commercialization rights for ocular medicines to the Company. The Company plans to continue to advance ocular medicines including EDIT-101 for Leber congenital amaurosis 10 (LCA10).

· EDIT-101 for LCA10

Continuation of dosing in BRILLIANCE Phase 1/2 clinical trial

Enrollment remains active and sites have reopened for dosing following a brief pause due to COVID-19. The study, which represents the first and only clinical trial to administer an in vivo CRISPR medicine, remains on track to complete dosing of the adult low-dose cohort (two patients) and dose at least one patient in the adult mid-dose cohort by the end of 2020.

Engineered Cell Medicines

· EDIT-301 for Sickle Cell Disease and Beta-Thalassemia

Preclinical data presented at EHA reinforces best-in-class potential

Data presented at the 25^th Congress of the European Hematology Association (EHA) showed that treatment with EDIT-301, which leverages the Company’s proprietary Cas12a (Cpf1) enzyme to edit directly at the HBG1/2 promoter, resulted in long-term in vivo editing with elevated and pan-cellular fetal hemoglobin expression. The Company remains on track to file an investigational new drug application (IND) for EDIT-301 by the end of 2020.

· EDIT-201 to Treat Solid Tumors

Declared candidate and initiated IND-enabling studies for allogeneic NK cell medicine

EDIT-201 is an allogeneic healthy-donor NK cell medicine for the treatment of solid tumors. Editas Medicine plans to present preclinical data on EDIT-201 at a scientific conference in the second half of 2020. The Company plans to file an IND for EDIT-201 in the second half of 2021.

Corporate

· Offering of Common Stock

Strengthened balance sheet with gross proceeds of approximately $216 million

Editas Medicine closed an underwritten offering of 6,900,000 shares of its common stock at a public offering price of $31.25 per share, before deducting underwriter discounts and commissions and estimated offering expenses. This included 900,000 shares issued upon exercise in full by the underwriter of its option to purchase additional shares. All shares in the offering were sold by Editas Medicine.

Editas Medicine established manufacturing agreements with Azzur Group and Catalent to support preclinical and clinical development of the Company’s portfolio of in vivo CRISPR and engineered cell medicines, including EDIT-101, EDIT-201, and EDIT-301. Following the termination of the 2017 agreement with Allergan, the Company has entered into a transition services agreement to transfer certain manufacturing material and processes for EDIT-101 and EDIT-102 from Allergan to Editas Medicine.

· Intellectual PropertyOn June 24, 2019, the U.S. Patent and Trademark Office declared an interference between

certain CRISPR/Cas9 patent applications submitted by the University of California, the University of Vienna, and Emmanuelle Charpentier and certain patents issued to the Broad Institute, Inc. (Broad) that have been licensed to Editas Medicine. Oral arguments in the interference took place on May 18, 2020. The Broad patents remain valid and in force. Foundational claims covering the use of CRISPR/Cas9 for gene editing in eukaryotic cells have issued and continue to issue to Broad as patents in the United States, Europe, Japan, and other jurisdictions.

· Balance Sheet

The Company expects that its existing cash, cash equivalents and marketable securities of $598.7 million at June 30, 2020, and anticipated interest income will enable it to fund its operating expenses and capital expenditures into 2023.

Second Quarter for 2020 Financial Results

Cash, cash equivalents, and marketable securities at June 30, 2020, were $598.7 million, compared to $415.0 million at March 31, 2020. The increase was largely due to the $203.7 million in net proceeds raised from the company’s recent equity offering.

For the three months ended June 30, 2020, net loss attributable to common stockholders was $23.6 million, or $0.43 per share, compared to $33.8 million, or $0.69 per share, for the same period in 2019.

· Collaboration and other research and development revenues were $10.7 million for the three months ended June 30, 2020, compared to $2.3 million for the same period in 2019. The $8.4 million increase was primarily attributable to $7.6 million in cash revenues received in connection with an out-license agreement and $0.8 million in non-cash revenue earned under our ongoing collaborations.

· Research and development expenses increased by $4.4 million, to $28.0 million for the three months ended June 30, 2020, from $23.6 million for the same period in 2019. The $4.4 million increase was primarily attributable to fees incurred related to licensing and sublicensing activities, research personnel growth to support our programs as well as our expansion of the development organization and facilities These increases were partially offset by a decrease in process and platform expenses and share-based compensation.

· General and administrative expenses decreased by $0.3 million to $14.1 million for the three months ended June 30, 2020, from $14.4 million for the same period in 2019. The $0.3 million decrease was primarily attributable to a decrease in the expense for professional service expenses and patent related fees which was partially offset by an increase is costs related to the hiring of key executives in the second half of 2019 and into 2020.
