Homology Medicines Announces Four Presentations on its Gene Editing and Gene Therapy Platform at the American Society of Gene & Cell Therapy Meeting

BEDFORD, Mass., April 24, 2017 /PRNewswire/ -- Homology Medicines, Inc., a genetic medicines company translating proprietary gene editing and gene therapy technologies into novel treatments for patients, announced today that data from its gene editing and gene therapy platform will be presented in an oral presentation and three poster presentations during the American Society of Gene & Cell Therapy (ASGCT) 20th Annual Meeting at the Marriott Wardman Park Hotel in Washington, D.C. from May 10-13, 2017.  

During the oral presentation, preclinical data will be presented for the first time demonstrating the precise, on-target in vivo gene editing capabilities of Homology Medicines' proprietary adeno-associated virus hematopoietic stem cell (AAVHSC) vectors. In poster presentations, the Company will also present additional new data related to its AAVHSC vectors, including quantitative gene editing data, biodistribution data in the peripheral and central nervous systems and data characterizing the frequency of pre-existing neutralizing antibodies in humans.

"Our presentations at ASGCT highlight the significant therapeutic potential of our gene editing and gene therapy platform, including its unique capabilities to induce precise and efficient gene editing without the need for nucleases as well as the superior biodistribution of our AAVHSC vectors for gene therapy," said Arthur Tzianabos, Ph.D., Chief Executive Officer of Homology Medicines. "We look forward to building upon this scientific information as we advance our platform to develop potential cures for patients with rare genetic diseases."    

Homology Medicines' presentations at the ASGCT Meeting are outlined below.
