Orchard Therapeutics Announces Eight Presentations Across Gene Therapy Portfolio at the American Society of Gene & Cell Therapy (ASGCT) 23rd Annual Meeting

  • Most Comprehensive Presentation of Orchard Clinical Data to Date; Spans Five Disease Areas and Highlights Broad Applicability of Hematopoietic Stem Cell Gene Therapy Approach
  • Accepted Abstracts Include Data on Investigational Gene Therapies for Neurometabolic Conditions, Including Updated Interim Data from Proof-of-Concept Trial in OTL-203 for Mucopolysaccharidosis Type I

BOSTON and LONDON, April 29, 2020 (GLOBE NEWSWIRE) -- Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, today announced eight upcoming presentations from across its neurometabolic, primary immune deficiency and blood disorder franchises at the American Society of Gene & Cell Therapy (ASGCT) 23rd Annual Meeting, which will take place online May 12-15, 2020, marking the company’s most comprehensive presentation of clinical data at a medical meeting to date. Accepted abstracts include data on three investigational treatments to address various neurometabolic disorders, including mucopolysaccharidosis type I (MPS-I), with high unmet need.

“Data to be presented at ASGCT represent tremendous progress in our mission and continued momentum across our clinical programs,” said Bobby Gaspar, M.D., Ph.D., chief executive officer of Orchard. “Collectively, these data demonstrate the potential of our hematopoietic stem cell gene therapy approach to correct the underlying genetic defects responsible for five different rare diseases, furthering our efforts toward realizing the full promise of this approach.”

Gaspar continues, “These programs are a result of tireless work by our research partners, and I want to thank them, the clinicians and patients involved in the clinical trials for showing how hematopoietic stem cell gene therapy can potentially change the lives of individuals with these devastating conditions.”

Of note, two of the eight presentations at ASGCT focus on new interim data from OTL-203, Orchard’s investigational gene therapy for the treatment of MPS-I, a rare, inherited neurometabolic disease caused by a deficiency of the alpha-L-iduronidase (IDUA) lysosomal enzyme that results in the accumulation of complex carbohydrates called glycosaminoglycans and is characterized by neurological, skeletal and cardiovascular problems.

The presentations also include the full integrated analysis of the registrational data set of OTL-101 for the treatment of adenosine deaminase severe combined immunodeficiency (ADA-SCID), which includes all patients treated in the U.S. with 24 months of follow-up; full results of the clinical proof-of-concept clinical trial for OTL-300 for the treatment of transfusion-dependent beta thalassemia, which achieved its primary outcome measures; and long-term outcomes in patients with ADA-SCID treated with Strimvelis®.

The presentations are listed below and the full abstracts for the oral and poster presentations are available on the ASGCT meeting website. All times listed are Eastern Time (ET).

*Patient was treated by the Royal Manchester Children’s Hospital (RMCH) under a “Specials” license, granted by the UK government for the use of an unlicensed pharmaceutical product in situations of high unmet need when there is no other treatment option available. Orchard holds the license to the MPS-IIIA investigational gene therapy product (OTL-201) and is funding the proof-of-concept clinical trial being conducted at RMCH, which utilizes the same technology and procedures that were used to treat this first MPS-IIIA patient.
