EDIT Editas Medicine Inc

Oral presentation of first achievement of in vivo retinal gene editing in non-human primates

Editas Medicine, Inc. (NASDAQ:EDIT), a leading genome editing company, today announced that six scientific abstracts have been accepted for presentation at the 20th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT). The meeting will take place May 10-13 in Washington, D.C.  The Company is presenting data on its pipeline and platform technologies to support ongoing development programs. 

Key Editas Medicine presentations at ASGCT will include data demonstrating:

• First report of results from in vivo gene editing of inherited retinal disease genes in non-human primates;
• CRISPR/Cas9-mediated editing and engraftment of hematopoietic stem cells preclinically for the treatment of β-hemoglobinopathies;
• Self-inactivating Cas9: A proprietary approach for controlling exposure while maintaining efficacy in virally-delivered Cas9 applications; and
• UDiTaS™: A proprietary genome editing analytical method to comprehensively characterize multiple forms of editing, including on- and off-target edits, large deletions, and translocations.

In addition, Editas scientists will be chairing sessions on cardiovascular and pulmonary gene and cell therapies, on AAV vector systems, and a scientific symposium on getting cures to patients.

“Editas Medicine is at the forefront of the rapidly-advancing science that is unlocking the potential of CRISPR for patients,” said Katrine Bosley, President and Chief Executive Officer, Editas Medicine. “These data at ASGCT showcase advances towards our goal of making medicines for patients suffering from genetically-defined diseases and, potentially, for more common genetically-treatable diseases as well.”

The complete list of Editas Medicine presentations is below.  Abstracts can be accessed on the ASGCT website at www.abstractsonline.com/pp8/#!/4399.
