Homology Medicines Announces Promotion of Albert Seymour, Ph.D., to President


BEDFORD, Mass., April 21, 2022 (GLOBE NEWSWIRE) -- Homology Medicines, Inc. (Nasdaq: FIXX), a genetic medicines company, announced today that Albert Seymour, Ph.D., Chief Scientific Officer, has been promoted to President of Homology. In addition to his role as CSO, Dr. Seymour will assume broader responsibilities for additional functional areas, including human resources, clinical development and operations, and commercial strategy.

“Albert has fostered a culture of scientific innovation and execution that brought our first gene therapy candidate to the clinic within three years from inception, and this was followed closely by two additional trial initiations, including our first nuclease-free in vivo gene editing program,” said Arthur Tzianabos, Ph.D., Chief Executive Officer of Homology Medicines. “I look forward to our continued work together, and I am confident in Albert’s ability to advance the pipeline while overseeing clinical execution of our three trials, which is a major focus of near-term milestones for Homology. I believe Albert’s added responsibilities will also ensure a seamless collaboration with the new AAV manufacturing company we formed recently with Oxford Biomedica that provides us preferred access to high-quality product.”

Dr. Seymour was one of the first employees of Homology and has served as CSO since joining alongside CEO Dr. Tzianabos in 2016. Dr. Seymour played an integral role in helping build Homology into a fully integrated company with capabilities spanning from discovery to product development and through to commercialization. Importantly, he drove the translation of the Company’s proprietary in vivo gene therapy and nuclease-free gene editing platform from early research and discovery to three clinical development programs for rare diseases. Under his scientific leadership, Dr. Seymour and his team forged a new path forward to assess and confirm on- and off-target gene integration at the molecular level, a critical step for the field as it continues to develop genetic medicines. His vision also led to the expansion of Homology’s technology platform with the recent launch of the GTx-mAb platform, a one-time gene therapy designed to produce and distribute antibodies from the liver, an innovative approach that can be applied to develop therapies for diseases with larger patient populations.

“I joined Homology because I recognized the potential of the AAVHSC technology to provide unique genetic medicine approaches to address significant unmet medical need in the rare disease community, and I am proud of the tremendous accomplishments that our team has achieved towards this goal,” said Dr. Seymour. “As I look to the future, I am thrilled to take on a broader role at Homology that leverages our collective expertise to advance our product candidates and execute on our three clinical trials, ultimately seeking to bring innovative genetic medicines to patients.”

Prior to his time at Homology, Dr. Seymour was the Senior Vice President and Head of Global Research and Nonclinical Development at Shire plc, where he led a team to deliver a sustained flow of rare disease therapeutics from idea to IND and supported the full R&D portfolio in the areas of toxicology, bioanalytics, drug metabolism and pharmacokinetics. Prior to that, Dr. Seymour served as the Vice President and Head of Drug Discovery and Translational Research at Shire, where he doubled the rare disease discovery portfolio in three years. Before Shire, he spent 14 years at Pfizer Inc. leading a team in the application of human genetics and computational biology to discover and develop therapeutics and pharmacogenomics strategies in diabetes, inflammatory diseases and oncology.
