Homology Webcast / Conference Call Scheduled for Friday, November 6 at 4:30 p.m. ET

BEDFORD, Mass., Nov. 05, 2020 (GLOBE NEWSWIRE) -- Homology Medicines, Inc. (Nasdaq: FIXX), a genetic medicines company, announced today the upcoming oral presentation of data from the dose-escalation portion of the Company’s ongoing Phase 1/2 pheNIX gene therapy clinical trial with HMI-102 for adults with phenylketonuria (PKU), the world’s first PKU gene therapy clinical trial. The data will be presented by pheNIX principal investigator Olaf Bodamer, M.D., Ph.D., FACMG, FAAP, Park Gerald Chair in Genetics & Genomics and Associate Chief of Genetics & Genomics at Boston Children’s Hospital, a premier center for metabolic disorders and the first site to enroll a patient in the pheNIX trial. The pheNIX trial results will be featured at the virtual New England Consortium of Metabolic Programs (NECMP) annual meeting, which is focused on new research in metabolic disorders, including PKU, on Friday, November 6. NECMP includes metabolic clinics, healthcare providers, patient organizations and others dedicated to increasing knowledge of metabolic disorders and improving delivery of healthcare to patients.

“We are pleased that additional data from our pheNIX trial, the first-ever gene therapy trial for PKU, will be shared for the first time by a respected leader in the field of metabolic disorders and directly with the PKU community as part of a featured, peer-reviewed scientific session,” stated Gabe Cohn, M.D., Chief Medical Officer of Homology Medicines. “The oral presentation by Dr. Bodamer will include data from three dose cohorts in the dose-escalation phase of our pheNIX trial, the results of which are informing the upcoming expansion phase of our study.”

About HMI-102

HMI-102 is an investigational gene therapy in clinical development for the treatment of phenylketonuria (PKU) in adults. HMI-102 is designed to encode the PAH gene, which is mutated in people with PKU, delivered via the liver-tropic AAVHSC15 vector. Homology has received Fast Track Designation and orphan drug designation for HMI-102 from the U.S. Food and Drug Administration (FDA), and orphan drug designation from the European Medicines Agency (EMA).

About Phenylketonuria (PKU)

PKU is a rare inborn error of metabolism caused by a mutation in the PAH gene. PKU results in a loss of function of the enzyme phenylalanine hydroxylase, which is responsible for the metabolism of phenylalanine (Phe), an amino acid obtained exclusively from the diet. If left untreated, toxic levels of Phe can accumulate in the blood and result in progressive and severe neurological impairment. Currently, there are no treatment options for PKU that target the underlying genetic cause of the disease. According to the National PKU Alliance, PKU affects nearly 16,500 people in the U.S. with approximately 350 newborns diagnosed each year. The worldwide prevalence of PKU is estimated to be 50,000 people.
