LONDON, Oct. 16, 2023 (GLOBE NEWSWIRE) -- Freeline Therapeutics Holdings plc (Nasdaq: FRLN) today announced that it will present new clinical data from its ongoing Phase 1/2 GALILEO-1 trial of FLT201, its adeno-associated virus (AAV) gene therapy candidate, in patients with Gaucher disease Type 1 at the European Society of Gene & Cell Therapy (ESGCT) 30th Annual Congress being held October 24-27, 2023 in Brussels, Belgium.
The oral presentation will include data on safety, tolerability, GCase enzyme activity, substrate, and hemoglobin and platelet levels from the first two patients treated with FLT201.
Details of the oral presentation are below:
Presentation Title: Results from GALILEO-1, a First-In-Human Clinical Trial of FLT201 Gene Therapy in Patients with Gaucher Disease Type 1
Presenter: Ozlem Goker-Alpan, MD, Lysosomal and Rare Disorders Research and Treatment Center
Date and Time: Wednesday, October 25 from 14:30-16:30 CEST (8:30-10:30 a.m. ET)
Session: 5B – Gene Therapy for Metabolic Diseases at Clinical Stage
Additional details on the meeting can be found at the ESGCT 30th Annual Congress website. The presentation materials will be available on the Investors section of Freeline’s website following presentation at the ESGCT Congress.
About Gaucher Disease
Gaucher disease is caused by a mutation in the GBA1 gene that results in abnormally low levels of glucocerebrosidase (GCase), an enzyme needed to metabolize a certain type of lipid. As a result, harmful substrates glucosylceramide (Gb-1) and glucosylsphingosine (lyso-Gb1) build up in cells that then accumulate in various organs, causing inflammation and dysfunction. Gaucher disease is hereditary and presents in various subtypes. Freeline is currently focused on Gaucher disease Type 1, the most common form of the disease, which affects the health of the spleen, liver, bone and lung. Despite treatment with existing therapies, many people with Gaucher disease continue to experience symptoms and disease progression. Gaucher disease affects approximately 18,000 people in the United States, United Kingdom, France, Germany, Spain, Italy and Israel.
FLT201 is an adeno-associated virus (AAV) gene therapy candidate that is currently being investigated in the Phase 1/2 GALILEO-1 clinical trial in adults with Gaucher disease Type 1. FLT201 is designed to generate durable increases in glucocerebrosidase (GCase) and reduce the accumulation of harmful substrates, with the aim of providing a one-time treatment that can stop disease progression, improve outcomes, and free people from lifelong treatment. FLT201 uses Freeline’s proprietary AAVS3 capsid to introduce a novel transgene into liver cells to produce a rationally engineered GCase variant. In preclinical studies, the GCase variant has demonstrated a greater than 20-fold increase in half-life at lysosomal pH conditions compared to wildtype human GCase. Preclinically, FLT201 has shown robust GCase expression, leading to significant GCase uptake and substrate reduction in key tissues.

About Freeline Therapeutics
Freeline is a clinical-stage biotechnology company focused on developing transformative gene therapies for chronic debilitating diseases. Freeline uses its proprietary, rationally designed AAV vector and capsid (AAVS3), along with novel promoters and transgenes, to deliver a functional copy of a therapeutic gene into human liver cells, thereby expressing a persistent functional level of the missing or dysfunctional protein into a patient’s bloodstream. The company is currently advancing FLT201, a highly differentiated gene therapy candidate that delivers a novel transgene, in a Phase 1/2 clinical trial in people with Gaucher disease type 1. Freeline has additional programs in research, including one focused on GBA1-linked Parkinson’s disease that leverages the same novel transgene as FLT201. Freeline is headquartered in the UK and has operations in the United States. For more information, visit www.freeline.life/or connect with Freeline on LinkedIn and X.
