Data show increased enzyme activity and reduction of harmful substrate, an established biomarker of efficacy in Fabry disease, in key tissues and organs
FLT190 currently being investigated in MARVEL-1 Phase 1/2 clinical trial
LONDON, Jan. 19, 2023 (GLOBE NEWSWIRE) — Freeline Therapeutics Holdings plc (Nasdaq: FRLN) today announced the publication of preclinical proof-of-concept data for its gene therapy candidate for Fabry disease, FLT190, in the Nature journal Gene Therapy. Fabry disease is a debilitating genetic disorder in which an enzyme deficiency leads to a harmful build-up of fat in the cells that causes progressive organ damage and can result in early death.
“People living with Fabry disease can experience debilitating symptoms and disease progression, even with current treatments. There is a pressing need for therapies with more lasting efficacy that are less burdensome on Fabry families,” said Pamela Foulds, M.D., Chief Medical Officer at Freeline. “We are encouraged by these preclinical data that support our ongoing Phase 1/2 clinical trial of FLT190 and our belief in FLT190 as a potential life-changing, one-time therapy for people with Fabry disease.”
Key findings that support development of FLT190 based on the preclinical evaluation in a Fabry mouse model and non-human primates following a single intravenous dose include:

Freeline is currently enrolling patients in the second dose cohort of MARVEL-1, an international, multicenter, adaptive dose-escalation and dose-expansion Phase 1/2 clinical trial in adult men (≥ 18 years) with classic Fabry disease. The company expects to share initial safety and efficacy data from the second dose cohort of MARVEL-1, as well as updated data from the first cohort, in the first half of 2023.
About Fabry Disease
Fabry disease is caused by a mutation in the GLA gene that results in the absence or deficient activity of α-galactosidase A (α-Gal A), an enzyme needed to metabolize a type of fat called globotriaosylceramide (Gb3). As a result of the deficiency, Gb3 accumulates in the lysosome of various cell types, leading to progressive damage to organs, including the kidney, heart and vasculature. Globotriaosylsphingosine (lyso-Gb3), a Gb3 degradation product and substrate of α-Gal A, may also contribute to disease pathology and is an established biomarker for the diagnosis and treatment of Fabry disease. Despite existing therapies, people with Fabry disease can continue to experience debilitating symptoms and even premature death, with renal failure and cardiac disease being the most common causes of death. Fabry disease affects approximately 16,000 people in the United States, European Union, United Kingdom and Japan.
FLT190 is an adeno-associated virus (AAV) gene therapy candidate that is currently being investigated in the MARVEL-1 Phase 1/2 clinical trial in adults with Fabry disease. FLT190 is designed to generate durable increases in α-Gal A levels and reduce substrate accumulation, with the aim of providing a one-time treatment that can stop disease progression and improve outcomes. FLT190 uses Freeline’s proprietary AAVS3 capsid to introduce a functional GLA gene into liver cells to produce α-Gal A. AAVS3 has been rationally designed to enable highly efficient liver cell transduction and durable enzyme production at low doses with a good safety profile. From the liver, α-Gal A can then circulate in the blood to be taken up by various tissues and transported to the cells and lysosomes to break down Gb3.

This press release contains statements that constitute “forward-looking statements” as that term is defined in the United States Private Securities Litigation Reform Act of 1995, including statements that express the opinions, expectations, beliefs, plans, objectives, assumptions or projections of Freeline Therapeutics Holdings plc (the “Company”) regarding future events or future results, in contrast with statements that reflect historical facts. All statements, other than historical facts, including statements regarding FLT190’s potential to be a life-changing, one-time therapy for people with Fabry disease and that the Company expects to share initial safety and efficacy data from the second dose cohort of the MARVEL-1 Phase 1/2 clinical trial of FLT190, as well as updated data from the first dose cohort, in the first half of 2023, are forward-looking statements. In some cases, you can identify such forward-looking statements by terminology such as “anticipate,” “intend,” “believe,” “estimate,” “plan,” “seek,” “project,” “expect,” “may,” “will,” “would,” “could” or “should,” the negative of these terms or similar expressions.
