BOSTON, Nov. 09, 2021 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (Nasdaq: INZY), a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of abnormal mineralization, today reported financial results for the third quarter ended September 30, 2021, and provided recent business highlights.

“The third quarter was marked by continued progress advancing our INZ-701 program for ENPP1 Deficiency and ABCC6 Deficiency,” said Axel Bolte, MSc, MBA, Inozyme’s co-founder, president, and chief executive officer. “We remain on track to enroll patients in both Phase 1/2 trials imminently, with preliminary biomarker and safety data expected in the first half of 2022.

Recent Updates

• On Track to Commence Phase 1/2 Trials in ENPP1 Deficiency and in ABCC6 Deficiency in Q4 2021: The Company remains on track to enroll patients in its Phase 1/2 clinical trials of INZ-701, its enzyme replacement therapy (ERT) in development for the treatment of mineralization disorders in Q4 2021, with preliminary biomarker and safety data expected from both trials in the first half of 2022.
• Presented Data on ENPP1 Program at the American Society for Bone and Mineral Research (ASBMR) 2021 Annual Meeting: The Company presented data from its ENPP1 Deficiency Natural History Study and gene therapy program supporting the urgent need for novel interventions for ENPP1 Deficiency.

Upcoming Anticipated Milestones

Third Quarter 2021 Financial Results

• Cash Position and Financial Guidance – Cash, cash equivalents, and investments were $125.3 million as of September 30, 2021. Based on its current plans and considering the impact of COVID-19-related clinical trial delays, the Company expects that its existing cash, cash equivalents, and investments will be sufficient to enable funding of its operating expenses and capital expenditure requirements into the first quarter of 2023.
  
  
• Research and Development (R&D) Expenses – R&D expenses were $9.3 million for the quarter ended September 30, 2021, compared to $25.2 million for the prior-year period. This decrease was primarily due to the non-recurring, non-cash purchase of in-process research and development intellectual property assets from Alexion Pharmaceuticals, Inc. in exchange for our stock in July 2020, as well as decreases in manufacturing operations based on the timing of production runs. These decreases were partially offset by increases in clinical trials costs to support the preparation for clinical trials and increased salaries and other employee-related costs to support the growth of the business.
  
  
• General and Administrative (G&A) Expenses – G&A expenses were $4.9 million for the quarter ended September 30, 2021, compared to $3.1 million for the prior-year period. The increase was primarily due to the growth in the number of G&A employees, an increase in legal fees related to new contracts and operations as a public company, and generally higher fees in areas such as audit, tax, and information technology to support the Company’s growth.
  
  
• Net Loss – Net loss was $14.3 million, or $0.60 loss per share, for the quarter ended September 30, 2021, compared to $28.1 million, or $1.55 loss per share, for the prior-year period.
  

About Inozyme Pharma

Inozyme Pharma, Inc. (Nasdaq: INZY) is a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of diseases of abnormal mineralization impacting the vasculature, soft tissue, and skeleton. Through our in-depth understanding of the biological pathways involved in mineralization, we are pursuing the development of therapeutics to address the underlying causes of these debilitating diseases. It is well established that two genes, ENPP1 and ABCC6, play key roles in a critical mineralization pathway and that defects in these genes lead to abnormal mineralization. We are initially focused on developing a novel therapy, INZ-701, to treat the rare genetic diseases of ENPP1 and ABCC6 Deficiencies.

Inozyme Pharma was founded in 2017 by Joseph Schlessinger, Ph.D., Demetrios Braddock, M.D., Ph.D., and Axel Bolte, MSc, MBA, with technology developed by Dr. Braddock and licensed from Yale University. For more information, please visit www.inozyme.com.
