Orchard Therapeutics Highlights Recent Accomplishments and 2019 Strategic Priorities as a Global Leader in Gene Therapy

Preparing Three Lead Programs for MLD, ADA-SCID and WAS for Regulatory Filings Over the Next Three Years

Recently Announced Clinical Proof-of-Concept in X-CGD Demonstrates Platform’s Transformative Potential

Advancing Earlier Stage Pipeline with Potential Clinical Proof-of-Concept for TDBT and Clinical Trial Application for MPS-IIIA

Entering 2019 in a Strong Financial Position with $340M in Cash and Investments

BOSTON and LONDON, Jan. 7, 2019 (GLOBE NEWSWIRE) – Orchard Therapeutics (NASDAQ: ORTX), a leading commercial-stage biopharmaceutical company dedicated to transforming the lives of patients with serious and life-threatening rare diseases through innovative gene therapies, today summarized recent accomplishments and 2019 strategic priorities in conjunction with its attendance at the 37th Annual J.P. Morgan Healthcare Conference in San Francisco. Mark Rothera, president and chief executive officer, will present a business overview outlining the company’s progress as a global leader in gene therapy on Wednesday, January 9, 2019 at 3:00 p.m. PT that will be webcast at ir.orchard-tx.com.

“2018 was a momentous year for Orchard, marked by the success of our acquisition and integration of GSK’s rare disease ex-vivo gene therapy portfolio, initial scaling of our manufacturing capabilities and completion of our initial public offering,” said Mr. Rothera. “2019 will continue the company’s evolution as a leader in gene therapy, with multiple clinical milestones supporting three regulatory filings over the next three years and growing manufacturing capabilities. We have a bold vision and are well on our way to delivering gene therapies that have the potential to transform the lives of patients with rare, life-threatening diseases worldwide with a single treatment.”

2019 Strategic Priorities

Neurometabolic Disorders

 

   

Release two and three-year follow-up data in 20 patients from the fresh formulation registrational trial of OTL-200 for metachromatic leukodystrophy (MLD)

 

   

Release engraftment data in the first three patients from the cryopreserved formulation clinical trial of OTL-200 for MLD

 

   

Submit clinical trial application (CTA) for OTL-201 for mucopolysaccharidosis type IIIA (MPS-IIIA) and support initiation of a clinical trial


Primary Immune Deficiencies

 

   

Release two-year follow-up data in 20 patients from the fresh formulation registrational trial of OTL-101 in adenosine deaminase severe combined immune deficiency (ADA-SCID)

 

   

Release engraftment data in 10 patients from a cryopreserved formulation clinical trial of OTL-101 in ADA-SCID

 

   

Release three-year follow-up data in eight patients from the fresh formulation registrational trial of OTL-103 in Wiskott-Aldrich syndrome (WAS)

 

   

Initiate cryopreservation formulation clinical trial for OTL-103 in WAS

 

   

Design and engage regulators on registrational trial for OTL-102 in X-linked chronic granulomatous disease (X-CGD), which recently achieved clinical proof-of-concept (link to full release here)

Hemoglobinopathies

 

   

Report clinical proof-of-concept data for OLT-300 in transfusion-dependent beta-thalassemia (TDBT)

Major 2018 Accomplishments

Pipeline Expansion and Advancement

 

   

Completed the strategic acquisition and subsequent integration of GSK’s rare disease ex-vivo gene therapy portfolio, including Strimvelis®, the only treatment for patients with ADA-SCID approved in the EU, along with clinical programs in MLD, WAS and TDBT

 

   

Completed pre-biologics license application (BLA) and CMC specific meetings with the U.S. Food and Drug Administration (FDA) for OTL-101 for ADA-SCID, following which the program remains on track for a BLA filing in the U.S. in 2020

 

   

Achieved clinical proof of concept for OTL-102 in X-CGD, demonstrating sustained levels of functioning neutrophils in patients after 12 months

 

   

Obtained Rare Pediatric Disease Designations from the FDA for OTL-200 for the treatment of MLD and OTL-201 for the treatment of MPS-IIIA

 

   

Obtained priority medicines (PRIME) designation from the European Medicines Agency (EMA) for OTL-300 for the treatment of TDBT

Corporate & Manufacturing Developments

 

   

Raised approximately $375 million in gross proceeds in 2018 from a Series C financing and underwritten initial public offering

 

   

Leased a manufacturing site in Fremont, CA and opened a Boston, MA corporate office. The manufacturing facility will enhance the company’s capacity to develop and deliver ex-vivo lentiviral vector and gene-corrected hematopoietic stem cells for a wide range of rare diseases on a global scale and will complement the existing network of partner CMOs that will underpin the launches for the first three programs.
