BOSTON and LONDON, Nov. 06, 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 announced financial results and business highlights for the quarter ended September 30, 2019, as well as the achievement of certain corporate milestones for the primary immune deficiencies franchise.

“We made important clinical and operational progress at Orchard over the past quarter, advancing our three lead programs toward regulatory submissions while moving additional programs through earlier stages of clinical development,” said Mark Rothera, president and chief executive officer of Orchard Therapeutics. “The data presented at several major medical conferences throughout the quarter showcase the profound impact that our hematopoietic stem cell-based gene therapies may have across multiple life-threatening diseases. We are working with care and urgency to make these therapies broadly available to patients who need them.”

Recent Achievements for the Neurometabolic Franchise

Metachromatic Leukodystrophy (MLD):

• Presented engraftment data in four patients receiving the cryopreserved formulation of OTL-200 for the treatment of MLD at the European Society of Gene & Cell Therapy (ESGCT) Annual Congress. The initial data showed that cellular engraftment using a cryopreserved formulation was similar to that observed using a fresh formulation, with the longest patient having 12 months of follow-up since treatment. Link to the full release here.
• In addition, an integrated analysis of 29 patients receiving the OTL-200 fresh formulation, which demonstrated positive clinical effects in the treatment of MLD and a consistent safety profile, was presented at the Society for the Study of Inborn Errors of Metabolism (SSIEM) 2019 Symposium. Link to the full release here.
• The company is on-track for a near-term Marketing Authorization Application (MAA) submission for OTL-200.

Mucopolysaccharidosis type I (MPS-I):

• Presented data from the ongoing proof-of-concept trial of OTL-203 for MPS-I at SSIEM. Evidence of engraftment and overexpression of the alpha-l-iduronidase (IDUA) enzyme in the peripheral blood and cerebrospinal fluid (CSF) was seen at the time of analysis in the six patients treated. Link to the full release here.
  -- An abstract has been accepted with updated proof-of-concept data for an oral presentation at the 61st American Society of Hematology (ASH) Annual Meeting in December.
  -- The study is expected to enroll eight patients by the first half of 2020, with primary endpoint results expected after one year of follow-up.

Sanfilippo Syndrome type A (MPS-IIIA):

• The clinical trial application for a proof-of-concept trial at the Royal Manchester Children’s Hospital (RMCH) for Orchard’s MPS-IIIA program (OTL-201) was recently accepted and enrollment is expected to begin later this year.
• This trial utilizes the same technology and procedures that were used to treat the first MPS-IIIA patient with ex vivo hematopoietic stem cell-based (HSC) gene therapy at RMCH under a “Specials” license.
• The patient treated under the “Specials” license continues to do well approximately 10 months after treatment, according to a statement made this week by the Manchester University NHS Foundation Trust.
  -- Six-month results indicate early evidence of metabolic correction with supranormal N-sulfoglucosamine sulfohydrolase (SGSH) enzyme activity in peripheral leukocytes and reduction of glycosaminoglycans (GAGs) in the urine, CSF and plasma.  

Upcoming Data Presentations for Primary Immune Deficiencies Franchise

• As announced in a separate release this morning, the company will present data from two registrational programs (OTL-103 for the treatment of Wiskott-Aldrich Syndrome (WAS) and OTL-101 for the treatment of adenosine deaminase severe combined immunodeficiency (ADA-SCID)) at the ASH meeting in December. Highlights include:
  -- OTL-103 for WAS: The registrational trial has met its key primary and secondary endpoints (n=8 at three years) with data from an integrated analysis (n=17) reinforcing the treatment benefits of gene therapy and durability of effect in additional patients. Successful engraftment was observed within three months, leading to an increase in WAS protein expression and a vector copy number that has been maintained for up to eight years.
  -- OTL-101 for ADA-SCID: Similar profiles and engraftment have been observed between the cryopreserved and fresh formulations of OTL-101, which represents an important achievement toward the future regulatory filing and potential approval of this investigational gene therapy and a key step toward global patient availability.

Third Quarter 2019 Financial Results

Cash, cash equivalents and investments as of September 30, 2019, were $366.2 million compared to $335.9 million as of December 31, 2018. The increase was primarily driven by proceeds from the company’s public equity offering in June 2019 and a credit facility entered in May 2019, partially offset by the net cash used to fund operations in the nine months ended September 30, 2019. During the three months ended September 30, 2019, the company’s cash used to fund operations included the paydown of accrued liabilities as of June 30, 2019, for the upfront payment and a milestone payment related to the license of a clinical-stage MPS-I program, or OTL-203.

During the three months ended September 30, 2019, the company recognized $1.9 million in revenue related to European sales of Strimvelis^®, the first gene therapy approved by the European Medicines Agency for ADA-SCID.

Research and development expenses were $28.5 million for the three months ended September 30, 2019 compared to $27.7 million in the same period in 2018. R&D expenses include the costs of clinical trials and preclinical work on the company’s portfolio of investigational gene therapies, as well as costs related to regulatory, manufacturing, license fees and milestone payments under the company’s agreements with third parties, and personnel costs to support these activities. The company expects R&D expenses to continue to increase as its programs advance through development.

Selling, general and administrative expenses were $14.2 million for the three months ended September 30, 2019, compared to $7.5 million in the same period in 2018. The increase was primarily due to increased investment to prepare for the potential commercialization of multiple late-stage programs, as well as higher costs to support public company operations.

Net loss attributable to ordinary shareholders was $36.7 million for the three months ended September 30, 2019, compared to $33.9 million in the same period in 2018. The increase in net loss as compared to the prior year was primarily due to higher costs related to pre-launch activities on the company’s later-stage programs in development and expenses associated with being a public company, partially offset by higher interest income. The company had 97.8 million weighted average ordinary shares outstanding for the three months ended September 30, 2019.

The company expects that its existing cash, cash equivalents and investments will enable funding of its anticipated operating and capital expenditure requirements into the second half of 2021.

“Orchard is well positioned to enter its next phase of growth as a company with potentially multiple commercial-stage gene therapies, building on a proven track record in identifying and treating patients with Strimvelis, the first ex vivo HSC gene therapy on the market,” said Frank Thomas, Orchard’s chief financial officer and chief business officer. “Having treated multiple patients with Strimvelis this quarter at a single center in Milan, Italy, we have deepened our understanding of the support required for patients and families along their treatment journey, successfully secured reimbursement for cross-border healthcare delivery within Europe and completed the manufacturing and release process scheduled and tailored for each individual patient. We look forward to expanding these capabilities and applying key learnings to future commercial gene therapies at multiple centers around the world using cryopreserved formulations of our future products, if approved.”
