Clinical and pre-clinical data from across the company’s portfolio will be featured in four oral and six poster presentations
Co-founder and Chief Executive Officer Bobby Gaspar to give invited talk exploring the curative potential of HSC gene therapy when coupled with widespread newborn screening
BOSTON and LONDON, Oct. 10, 2022 (GLOBE NEWSWIRE) -- Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, today announced multiple presentations at the 29th Annual Congress of the European Society of Gene & Cell Therapy (ESGCT), taking place October 11-14, 2022, in Edinburgh.
Clinical and pre-clinical data from across the company’s hematopoietic stem cell (HSC) gene therapy portfolio will be featured in four oral and six poster presentations, including an invited talk from Bobby Gaspar, M.D., Ph.D., co-founder and chief executive officer of Orchard Therapeutics exploring the curative potential of HSC gene therapy when coupled with widespread newborn screening.
Additionally, Orchard’s clinical collaborator Bernhard Gentner M.D., Ph.D., group leader of the Translational Stem Cell and Leukemia Research Unit at the San Raffaele-Telethon Institute for Gene Therapy (SR-TIGET) in Milan and staff hematologist in the Hematology and Bone Marrow Transplantation Unit of San Raffaele Hospital will be giving an invited presentation on the company’s investigational HSC gene therapy OTL-203 for MPS-IH.
Other featured presentations include several accepted abstracts highlighting the company’s newborn screening and early research efforts, including a poster on its internally discovered HSC-CAR Treg gene therapy as a potential treatment for severe chronic autoimmune disorders.
“Together with our clinical and research partners, we’re proud of our presence at the upcoming ESGCT Annual Congress,” said Leslie Meltzer, Ph.D., chief medical officer of Orchard Therapeutics. “Alongside our extensive body of clinical data and real-world evidence in MLD, our programs are showing the transformative potential of HSC gene therapy across many different genetic diseases with high unmet medical need.”

About Libmeldy / OTL-200
Libmeldy (atidarsagene autotemcel), also known as OTL-200, has been approved by the European Commission for the treatment of metachromatic leukodystrophy (MLD) in eligible early-onset patients characterized by biallelic mutations in the ARSA gene leading to a reduction of the ARSA enzymatic activity in children with i) late infantile or early juvenile forms, without clinical manifestations of the disease, or ii) the early juvenile form, with early clinical manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive decline. Libmeldy is the first therapy approved for eligible patients with early-onset MLD.
The most common adverse reaction attributed to treatment with Libmeldy was the occurrence of anti-ARSA antibodies. In addition to the risks associated with the gene therapy, treatment with Libmeldy is preceded by other medical interventions, namely bone marrow harvest or peripheral blood mobilization and apheresis, followed by myeloablative conditioning, which carry their own risks. During the clinical studies of Libmeldy, the safety profiles of these interventions were consistent with their known safety and tolerability.
For more information about Libmeldy, please see the Summary of Product Characteristics (SmPC) available on the EMA website.
Libmeldy is approved in the European Union, UK, Iceland, Liechtenstein and Norway. OTL-200 is an investigational therapy in the U.S.
Libmeldy was developed in partnership with the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy.
About Orchard Therapeutics
At Orchard Therapeutics, our vision is to end the devastation caused by genetic and other severe diseases. We aim to do this by discovering, developing and commercializing new treatments that tap into the curative potential of hematopoietic stem cell (HSC) gene therapy. In this approach, a patient’s own blood stem cells are genetically modified outside of the body and then reinserted, with the goal of correcting the underlying cause of disease in a single treatment.
In 2018, the company acquired GSK’s rare disease gene therapy portfolio, which originated from a pioneering collaboration between GSK and the San Raffaele Telethon Institute for Gene Therapy in Milan, Italy. Today, Orchard is advancing a pipeline spanning pre-clinical, clinical and commercial stage HSC gene therapies designed to address serious diseases where the burden is immense for patients, families and society and current treatment options are limited or do not exist.
Orchard has its global headquarters in London and U.S. headquarters in Boston. For more information, please visit www.orchard-tx.com, and follow us on Twitter and LinkedIn.
