A Bet on a Unique Set of Vectors

Homology Medicines is developing a range of genetic therapies based on a unique set of adeno-associated virus vectors derived from human hematopoietic stem cells that allow it to target a wide range of tissues. It is developing both gene therapies and gene editors simultaneously using these vectors. It’s lead program is an experimental gene therapy for phenylketonuria or PKU, a rare, genetic metabolic condition that causes an enzyme deficiency that results in an inability to breakdown the amino acid phenylalanine, which is common in protein containing foods. We spoke to Arthur Tzianabos, CEO of Homology Medicines, about the company’s genetic therapies, its program in PKU, and how it pairs its vectors and approach to meet the needs of a given condition.
