- Company Announced IND Clearance Today for Phase 1/2 Clinical Trial -
BEDFORD, Mass., April 4, 2019 – Homology Medicines, Inc. (Nasdaq: FIXX), a genetic medicines company, announced today preclinical data demonstrating that HMI-102, its gene therapy candidate for the treatment of phenylketonuria (PKU), restored the normal phenylalanine metabolic pathway as evidenced by measurements of key biomarkers in the disease model. The presentation at the ACMG Annual Clinical Genetics Meeting demonstrated long-term durability of the one-time administration of HMI-102 in reducing serum phenylalanine (Phe) and increasing tyrosine levels, due to an increase in phenylalanine hydroxylase (PAH) enzyme activity. HMI-102 also demonstrated reduction in brain Phe and the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA), as well as a positive impact on melanin production.
“As we prepare to start our Phase 1/2 clinical trial with HMI-102 for adults with PKU, we are pleased to share further evidence that our one-time gene therapy candidate has restored the normal biochemical pathway that is lost in PKU,” stated Albert Seymour, Ph.D., Chief Scientific Officer of Homology Medicines. “We believe the data support the potential for HMI-102 to address the underlying genetic cause of PKU, and we look forward to advancing this product candidate forward and reporting initial clinical data this year.”
As previously reported today, the U.S. Food and Drug Administration (FDA) provided clearance for Homology to begin its Phase 1/2 clinical trial with HMI-102. Homology’s presentation received a Top Rating from the ACMG.

About Phenylketonuria (PKU)
PKU is a rare, inherited inborn error of metabolism caused by a mutation in the PAH gene. The current standard of care is a highly restrictive diet, but it is not always effective, and there are currently no treatments available that address the genetic defect in PKU. If left untreated, PKU can result in progressive and severe neurological impairment. PKU affects approximately 15,000 people in the U.S., and an estimated 300 newborns are diagnosed each year.
