CAMBRIDGE, Mass., Nov. 05, 2020 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today reported business highlights and financial results for the third quarter of 2020.

“We were pleased to regain full operating control of our ocular programs per our new agreement with AbbVie, which provides us with important flexibility. We have finished dosing the first cohort with EDIT-101 in the landmark BRILLIANCE trial and enrollment remains active,” said Cynthia Collins, Chief Executive Officer of Editas Medicine.

Ms. Collins continued, “The advancements in our ocular portfolio are complemented by the strategic development of our engineered cell medicines. We are on track to file the IND for EDIT-301 for sickle cell disease in the fourth quarter and are eager to present additional data on this potentially best-in-class medicine and our large-scale manufacturing process at the upcoming American Society of Hematology Annual Meeting. Substantial progress has also been made in the development of EDIT-201, an allogeneic NK cell medicine to treat solid tumors. Preclinical data to be presented at ASH show enhanced tumor killing with EDIT-201 compared to unedited NK cells, and additional data on this program will be featured at the upcoming Society for Immunotherapy of Cancer’s Annual Meeting.”

Recent Achievements and Outlook

In Vivo CRISPR Medicines  

• EDIT-101 for LCA10
  BRILLIANCE Phase1/2 adult low-dose cohort completed
  Editas Medicine (Company) has completed dosing of the first cohort of adult patients with visual light perception only administered the low dose of EDIT-101. Trial enrollment remains active but has experienced a slowdown due to the ongoing impact of the COVID-19 pandemic. 

• Ocular Medicines
  Regained full control of ocular medicines
  Editas Medicine terminated its 2017 agreement with Allergan, now part of AbbVie, and entered a new agreement with AbbVie that returned development and commercialization rights for ocular medicines to Editas Medicine. As part of the new agreement, AbbVie has transferred supplier contracts, including with the contract research organization (CRO), as well as sponsorship of the investigational new drug application (IND) for the BRILLIANCE Phase 1/2 clinical trial to Editas Medicine. The Company plans to continue to advance ocular medicines, including EDIT-101 for Leber congenital amaurosis 10 (LCA10).

Ex Vivo CRISPR Cell Medicines  

• EDIT-301 for Sickle Cell Disease and Beta-Thalassemia
  On track for IND filing by end of 2020
  Editas Medicine continues to prepare for a Phase 1/2 clinical trial evaluating EDIT-301 for the treatment of sickle cell disease. The Company has completed preclinical toxicology studies, identified a lead principal investigator, and engaged a CRO. Clinical trial materials are being manufactured by Editas Medicine. The Company remains on track to file an IND for the treatment of sickle cell disease by the end of 2020.
  
  Granted Rare Pediatric Disease Designation for treatment of sickle cell disease
  EDIT-301 was granted Rare Pediatric Disease Designation by the U.S. Food and Drug Administration (FDA). Under the FDA’s Rare Pediatric Disease Designation and Voucher programs, a sponsor who receives approval for a drug or biologic for a rare pediatric disease may be eligible for a voucher that can be redeemed to receive priority review of a subsequent marketing application for a different product.
  
  ASH data to highlight efficient editing with clinical scale manufacturing process
  Preclinical data to be presented at the 62^nd American Society of Hematology Annual Meeting & Exposition (ASH) show CRISPR/Cas12a editing efficiency of the HBG1/2 promoter exceeding 90 percent after long term engraftment in mice of healthy donor hematopoietic stem cells manufactured at clinical scale. 

• EDIT-201 to Treat Solid Tumors
  Data demonstrating enhanced tumor killing to be presented at SITC and ASH
  EDIT-201 is comprised of healthy donor natural killer (NK) cells that have been edited using a proprietary CRISPR/Cas12a ribonucleoprotein to knock out the CISH and TGFβR2 genes. At ASH, the Company will present data showing that NK cells with CISH and TGFβR2 knockouts are more potent than unedited cells in vitro. The Company will also show that the combination of therapeutic antibodies with EDIT-201 further enhances tumor killing. Data on EDIT-201 will also be presented at the Society for Immunotherapy of Cancer’s 35^th Anniversary Annual Meeting. 

• CRISPR iPSC NK (iNK) Cell Medicines to Treat Solid Tumors
  Proprietary CRISPR/Cas12a editing of iPSCs enhances iNK tumor killing 
  Preclinical data to be presented at ASH detail a CRISPR/Cas12a induced pluripotent stem cell (iPSC) editing platform. The Company will show that knockout of CISH and TGFβR2 with the proprietary CRISPR/Cas12a editing platform enhances iNK cell tumor killing in a spheroid model.

Corporate 

• Intellectual Property
  The U.S. Patent and Trademark Office (USPTO) recently issued a decision in the ongoing patent interference between the University of California, the University of Vienna, Emmanuelle Charpentier (CVC) and the Broad Institute, Inc. (Broad) regarding certain Broad CRISPR/Cas9 patents Editas Medicine exclusively licenses. The USPTO granted Broad’s motion for priority benefit while denying CVC priority benefit to its two earliest provisional patent applications. As a result, Broad enters the priority phase of the interference as “Senior Party” while CVC remains the “Junior Party” for purposes of determining which entity was the first to invent the use of CRISPR/Cas9 for gene editing in eukaryotic cells. The Senior Party is presumed to be the first inventor, thus, the Junior Party, here CVC, has the burden of overcoming this presumption. 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, China, and other jurisdictions. 

• Balance Sheet
  The Company expects that its existing cash, cash equivalents and marketable securities of $541.3 million as of September 30, 2020, and anticipated interest income will enable it to fund its operating expenses and capital expenditures into 2023.        

Third Quarter 2020 Financial Results

Cash, cash equivalents, and marketable securities as of September 30, 2020, were $541.3 million, compared to $598.7 million as of June 30, 2020.

For the three months September 30, 2020, net income attributable to common stockholders was $7.8 million, or $0.12 per share, diluted, compared to net loss of $32.9 million, or $0.66 per share, for the same period in 2019. 

• Collaboration and other research and development revenues increased by $59.0 million, to $62.8 million for the three months ended September 30, 2020 from $3.8 million for three months ended September 30, 2019. This increase was primarily attributable to the recognition of $59.9 million of previously deferred revenue as a result of the termination of our strategic alliance with Allergan.

• Research and development expenses increased by $11.2 million, to $33.9 million for the three months ended September 30, 2020 from $22.7 million for the three months ended September 30, 2019. The $11.2 million increase was primarily attributable to an increase in expenses related to the clinical and manufacturing development of EDIT-101 and our other programs, including a including a one-time in-process research and development expense of $5.0 million for re-acquiring the rights to EDIT-101 from Allergan. In addition, the Company continued to invest in the research and development organization which resulted in an increase in employee and facility related expenses as compared to the prior year.
  
  
• General and administrative expenses increased by $4.2 million to $19.9 million for the three months ended September 30, 2020, from $15.7 million for the same period in 2019. The $4.2 million increase was primarily attributable to an increase in expense for professional service fees incurred by the Company in connection with the termination of the Allergan agreement as well as an increase in employee and facility related expenses.
