Company to host virtual investor webinar to review symposium data on Tuesday, February 9, 2021 at 4:30 p.m. ET

BOSTON and LONDON, Jan. 28, 2021 (GLOBE NEWSWIRE) -- Orchard Therapeutics(Nasdaq: ORTX), a global gene therapy leader, today outlined nine upcoming presentations from its neurodegenerative portfolio to be featured at the 17th Annual WORLDSymposium being held on February 8-12, 2021. Accepted abstracts include clinical data from three of its hematopoietic stem cell (HSC) gene therapy programs OTL-200 for MLD, OTL-203 for MPS-I and OTL-201 for MPS-IIIA as well as data supporting Orchards multi-pronged patient identification and market access strategies for eligible MLD patients in Europe.

Together with our clinical partners, were proud of our presence at the upcoming WORLDSymposium, which for the first time features clinical data on cognitive function and growth in all eight MPS-I patients treated with gene therapy, said Bobby Gaspar, M.D., Ph.D., chief executive officer of Orchard.

About Libmeldy / OTL-200Libmeldy (autologous CD34+ cell enriched population that contains hematopoietic stem and progenitor cells (HSPC) transduced ex vivo using a lentiviral vector encoding the human arylsulfatase-A (ARSA) gene), also known as OTL-200, has been approved by the European Commission for the treatment of 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, 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 not approved outside of the European Union, UK, Iceland, Liechtenstein and Norway. OTL-200 is an investigational therapy in the US.

Libmeldy was developed in partnership with the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy.
