LEXEO intends to initiate a Phase I/II clinical trial of LX2006 in patients with FA-associated cardiomyopathy.
FREMONT, CA: LEXEO Therapeutics, a clinical-stage gene therapy company, announces that the US Food and Drug Administration (FDA) has designated LX2006 to treat Friedreich's ataxia as a Rare Pediatric Disease and an Orphan Drug (FA). LX2006 is an intravenous (IV)-based adeno-associated virus (AAV)-mediated gene therapy encodes the human frataxin gene. In addition, LX2006 has been granted designations for cardiac disease and broader symptoms associated with FA.

The FDA designates severe and life-threatening diseases as Rare Pediatric Diseases when they primarily affect children ages 18 years or younger and affect fewer than 200,000 people in the United States. LEXEO may be eligible to receive a priority review voucher that may be sold or transferred if a biologics license application (BLA) for LX2006 is approved.
The FDA designates drugs or biologics as Orphan Drugs when intended to treat a disease that affects fewer than 200,000 people in the United States. Orphan drug programs are eligible for a variety of development incentives.
“Being granted both Rare Pediatric Disease and Orphan Drug designation shows the tremendous urgency for new, impactful therapeutic approaches such as LX2006 for people diagnosed with Friedreichs ataxia,” says R. Nolan Townsend, Chief Executive Officer of LEXEO Therapeutics. “It is critical that we advance new disease-modifying therapies with the potential to transform the lives of FA patients, and we look forward to continuing our collaboration with the FDA as we advance LX2006 through clinical development.”
FA is a rare, multisystem degenerative disorder that affects approximately one in every 50,000 people in the United States. An inherited disease caused by a gene mutation impairs the protein frataxin's average production, essential for cell mitochondrial function. It is inherited autosomallyrecessively and typically manifests as impaired muscle coordination (ataxia) that worsens over time, normally progressing to severe heart conditions that can result in heart failure, the most common cause of death in FA patients.
