CAMBRIDGE, Mass., May 07, 2020 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today reported business highlights and financial results for the first quarter of 2020.

“The COVID-19 pandemic has given rise to unprecedented circumstances for Editas and the broader life sciences community,” said Cynthia Collins, Chief Executive Officer of Editas Medicine. “Our top priority is safety and we have implemented measures to ensure that safety comes first while mitigating the disruption to our business operations as much as possible. I want to thank our employees, patients, and partners for their resilience during this difficult time.”

Ms. Collins continued, “Despite these obstacles, 2020 has been a momentous year for Editas. We are incredibly proud to have advanced an entirely new class of medicines to the clinic with the first ever administration of EDIT-101, our in vivo CRISPR gene editing medicine for LCA10. In addition, we expect continued execution throughout 2020 which will include the expansion of our clinical programs through an expected IND filing for EDIT-301, our first engineered cell medicine and potentially best-in-class treatment for sickle cell disease and beta-thalassemia.”

Recent Achievements and Outlook

Business Outlook

• COVID-19 Impact
  Potential business interruptions due to the COVID-19 outbreak
  Editas Medicine (Company) continues to evaluate the impact of the global COVID-19 pandemic on the continuity of the Company’s research, clinical trial activity, and business outlook. The Company has taken numerous steps to protect its employees, patients, and partners, while working to ensure the productivity of its business operations. As of March 12, the Company transitioned to remote working for office-based personnel. In addition, essential laboratory, manufacturing, and related support activities have been subject to precautionary measures to ensure the safety of our workforce.

In Vivo CRISPR Medicines 

• EDIT-101 for LCA10 
  First in vivo CRISPR medicine administered to a patient
  Editas Medicine and Allergan announced the treatment of the first patient in the BRILLIANCE Phase 1/2 clinical trial of EDIT-101 at Oregon Health & Science University Casey Eye Institute, a world-recognized academic eye center. The study has been cleared to continue based on a review of safety data on the first patient. The Company plans to complete dosing of the adult low-dose cohort and to dose at least one patient of the adult mid-dose cohort by the end of 2020.

• EDIT-102 for Usher Syndrome 2A
  Ready for IND-enabling studies pending Allergan option exercise
  Under the terms of its 2017 alliance agreement with Allergan, Editas Medicine has delivered a preclinical data package to Allergan for potential licensing. EDIT-102 is ready for IND-enabling studies pending Allergan’s option exercise. A decision is expected by the third quarter of 2020.

• Autosomal Dominant Retinitis Pigmentosa 4
  Nomination of development candidate delayed to 2021
  Due to interruptions from the COVID-19 outbreak, Editas Medicine is delaying to 2021 the declaration of a development candidate for an experimental medicine to treat autosomal dominant retinitis pigmentosa 4.

Engineered Cell Medicines 

• EDIT-301 for Sickle Cell Disease and Beta-Thalassemia
  IND filing expected by end of 2020
  Editas Medicine is developing EDIT-301 using Cas12a (Cpf1), a proprietary enzyme, as a potentially best-in-class medicine to treat sickle cell disease and beta-thalassemia. Preclinical in vivo toxicology studies are in progress and the Company expects to file an IND for sickle cell disease 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 natural killer (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.

Corporate

• Leadership
  The Company has strengthened its executive leadership team with the appointment of Clare Carmichael as Chief Human Resources Officer (CHRO). Clare brings more than 30 years of human resources experience and joins Editas Medicine from Wave Life Sciences, a clinical-stage genetics medicine company, where she served as CHRO.

• Intellectual Property
  On 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 have been scheduled for 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 $415.0 million at March 31, 2020, and anticipated interest income will enable it to fund its operating expenses and capital expenditures for at least the next 24 months. The Company remains committed to diligently managing expenses to maintain a strong balance sheet moving forward.                    

First Quarter for 2020 Financial Results

Cash, cash equivalents, and marketable securities at March 31, 2020, were $415.0 million, compared to $457.1 million at December 31, 2019.

For the three months ended March 31, 2020, net loss attributable to common stockholders was $37.7 million, or $0.69 per share, compared to $29.2 million, or $0.60 per share, for the same period in 2019.

• Collaboration and other research and development revenues were $5.7 million for the three months ended March 31, 2020, compared to $2.1 million for the same period in 2019. The $3.7 million increase was primarily attributable to an increase in revenue recognized pursuant to our strategic alliance with Allergan.

• Research and development expenses increased by $18.7 million, to $34.6 million for the three months ended March 31, 2020, from $15.8 million for the same period in 2019. The $18.7 million increase was primarily attributable to increased process and platform development expenses driven by increased manufacturing and clinical related costs, including costs under our profit-sharing arrangement with Allergan in the United States for EDIT-101, and expenses incurred related to an in-license arrangement entered into during the first quarter of 2020.
   
• General and administrative expenses increased by $0.3 million to $17.8 million for the three months ended March 31, 2020, from $17.5 million for the same period in 2019. The $0.3 million increase was primarily attributable to increased employee related expenses.

About the Editas Medicine-Allergan Alliance
In March 2017, Editas Medicine and Allergan Pharmaceuticals International Limited (Allergan) entered a strategic alliance and option agreement under which Allergan received exclusive access and the option to license up to five of Editas Medicine’s genome editing programs for ocular diseases, including EDIT-101 (AGN-151587). Under the terms of the agreement, Allergan is responsible for development and commercialization of optioned products, subject to Editas Medicine’s option to co-develop and share equally in the profits and losses of two optioned products in the United States. In August 2018, Allergan exercised its option to develop and commercialize EDIT-101 globally for the treatment of LCA10. Additionally, Editas Medicine exercised its option to co-develop and share equally in the profits and losses from EDIT-101 in the United States. Editas Medicine is also eligible to receive development and commercial milestones, as well as royalty payments on a per-program basis. The agreement covers a range of first-in-class ocular programs targeting serious, vision-threatening diseases based on Editas Medicine’s unparalleled CRISPR genome editing platform, including CRISPR/Cas9 and CRISPR/Cpf1 (also known as Cas12a).
