BOSTON, March 25, 2021 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (Nasdaq: INZY), a rare disease biopharmaceutical company developing novel therapeutics for the treatment of diseases of abnormal mineralization, today reported financial results for the full year ended December 31, 2020 and provided recent business highlights.

“2020 was a foundational year for Inozyme as we laid the groundwork to become a clinical stage company focused on the biology of mineralization. We have significantly expanded our team and operational footprint, ensuring we have the resources required to bring INZ-701 - our lead product candidate - into two planned first-in-human clinical studies in patients with ENPP1 deficiency and ABCC6 deficiency,” said Axel Bolte, MSc, MBA, co-founder, president, and chief executive officer of Inozyme Pharma. “ENPP1 deficiency is a systemic, progressive, and chronic disease that occurs over a patient’s lifetime, starting as early as fetal development, and spanning into adulthood, with devastating and often fatal effect. ABCC6 deficiency is a calcification disorder with an onset in adolescence and progressive worsening and high morbidity.”

Mr. Bolte continued, “Based on discussions with U.S. and European regulatory authorities, we plan to initiate our Phase 1/2 clinical trial in ENPP1 deficiency in the first half of 2021 and our Phase 1/2 clinical trial in ABCC6 deficiency by mid-2021.”

Recent Business Highlights

• Granted Orphan Drug Designation for INZ-701 for ABCC6 Deficiency – Inozyme recently received orphan drug designation by the U.S. Food and Drug Administration for INZ-701 for the treatment of patients with ABCC6 deficiency.
• Received Clearance to Proceed in U.S. and U.K. with Phase 1/2 Clinical Trial of INZ-701 for the Treatment of ENPP1 Deficiency – the Company expects to initiate the Phase 1/2 trial in the first half of 2021 and to provide preliminary safety and biomarker data in the second half of 2021.
• Completed the Burden of Disease Patient Study – this study provides an overview of the burden of disease in patients with ENPP1 deficiency and ABCC6 deficiency. The study has been accepted as poster presentations at three scientific conferences in the second quarter of 2021.
• Completed the Healthy Volunteer Pyrophosphate (PPi) Study – this study validates the highly sensitive assay that will be used to evaluate INZ-701 in clinical trials. The results of this study will be presented at medical conferences later in the year.
• Advanced Gene Therapy Research and Development – Inozyme progressed research and preclinical proof-of-concept work in demonstrating the ability to raise PPi levels using a gene therapy approach in animal models.
  

Upcoming Anticipated Milestones

The Company also announced the following anticipated milestones for the INZ-701 clinical development program, subject to COVID-19-related restrictions:

• ENPP1 Deficiency
  • H1 2021: Initiate prospective natural history study
  • H1 2021: Initiate Phase 1/2 clinical trial
  • H2 2021: Report preliminary safety and biomarker data from Phase 1/2 clinical trial
• ABCC6 Deficiency
  • H1 2021: File Clinical Trial Applications
  • Mid-2021: Initiate Phase 1/2 clinical trial
  • By the End of 2021: Report preliminary safety and biomarker data from Phase 1/2 clinical trial

Financial Results for the Year Ended December 31, 2020

• Cash Position and Financial Guidance – Cash, cash equivalents, and investments were $159.9 million as of December 31, 2020. Based on its current plans, 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 second half of 2022.
• Research and Development (R&D) Expenses – R&D expenses were $46.5 million for the year ended December 31, 2020, compared to $16.2 million for the year ended December 31, 2019. The increase was primarily due to an increase of $17.8 million resulting from the non-recurring, non-cash purchase of in-process research and development intellectual property assets from Alexion Pharmaceuticals in exchange for stock of the Company in July 2020; costs associated with preclinical studies and clinical preparation activities with the Company’s contract research organization; and growth in the number of R&D employees.
• General and Administrative (G&A) Expenses – G&A expenses were $10.5 million for the year ended December 31, 2020, compared to $4.6 million for the year ended December 31, 2019. The increase was primarily due to the growth in the number of G&A employees; an increase in legal fees related to patents, 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 $56.4 million, or $5.11 loss per share, for the year ended December 31, 2020, compared to $19.7 million, or $16.67 loss per share, for the year ended December 31, 2019.

About Inozyme Pharma

Inozyme Pharma, Inc. (Nasdaq: INZY), is a 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 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.
