BOSTON, March 15, 2022 (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 full year ended December 31, 2021, and provided recent business highlights.

“2021 was a transformational year for Inozyme, as we continued to progress our INZ-701 program and graduated to a clinical-stage company. We initiated our first clinical trial for patients with ENPP1 Deficiency and are screening patients for our clinical trial in ABCC6 Deficiency, and have continued to deepen our understanding of the pathophysiology of these rare and devastating mineralization disorders,” said Axel Bolte, MSc, MBA, Inozyme’s co-founder, president, and chief executive officer. “We firmly believe that INZ-701 could be a meaningful intervention in patients with ENPP1 Deficiency and ABCC6 Deficiency, and we are committed to realizing the full potential of this promising therapy.”

Recent Updates

  • Phase 1/2 Trial of INZ-701 in Adults with ENPP1 Deficiency. Patient dosing is underway in the Company’s Phase 1/2 trial of INZ-701 in patients with ENPP1 Deficiency. The Company remains on track to report preliminary biomarker and safety data in the first half of 2022.
  • Phase 1/2 Trial of INZ-701 in Adults with ABCC6 Deficiency. Patient screening is underway in the Company’s Phase 1/2 trial of INZ-701 in patients with ABCC6 Deficiency. The Company expects to enroll its first patient in the Phase 1/2 trial in the second quarter of 2022. The Company remains on track to report preliminary biomarker and safety data in the first half of 2022.
  • First Patient Enrolled in Longitudinal Retrospective Natural History Study in ENPP1 Deficiency and ABCC6 Deficiency. This study is designed to test and validate findings from the Company’s Cross-sectional Retrospective Natural History Study.
  • Strengthened Management Team with Two Executive Appointments. The Company recently announced the appointment of Sanjay S. Subramanian, MBA, as chief financial officer, effective as of March 21, 2022, and Soojin Kim, Ph.D., as senior vice president and chief technical operations officer.
  • Presented Data on ENPP1 Program. At the American Society for Bone and Mineral Research (ASBMR) 2021 Annual Meeting in October 2021, 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

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

  • ENPP1 Deficiency
    • H1 2022: Report preliminary safety and biomarker data from Phase 1/2 clinical trial
    • Q2 2022: Initiate prospective natural history study
  • ABCC6 Deficiency
    • Q2 2022: First patient dosing in Phase 1/2 clinical trial
    • H1 2022: Report preliminary safety and biomarker data from Phase 1/2 clinical trial
    • Q2 2022: Initiate prospective natural history study

Financial Result for the Year Ended December 31, 2021

  • Cash Position and Financial Guidance – Cash, cash equivalents, and investments were $111.8 million as of December 31, 2021. Based on its current plans, the Company expects that its existing cash, cash equivalents, and investment will be sufficient to fund its operating expenses and capital expenditures into the first quarter of 2023.
  • Research and Development (R&D) Expenses – R&D expenses were $37.7 million for the year ended December 31, 2021, compared to $46.5 million for the year ended December 31, 2020. 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 the Company’s stock in in July 2020, as well as decreases in research and development expenses such as toxicology studies and decreases in manufacturing operations based on the timing of production runs, partially offset by increases in clinical trials costs and increased employee-related costs to support the growth of the business.
  • General and Administrative (G&A) Expenses – G&A expenses were $18.9 million for the year ended December 31, 2021, compared to $10.5 million for the year ended December 31, 2020. The increase was primarily due to the growth in the number of G&A employees, an increase in legal fees and generally higher fees in areas such as audit, tax, and information technology to support the Company’s growth and operations as a public company.
  • Net Loss – Net loss was $56.6 million, or $2.40 loss per share, for the year ended December 31, 2021, compared to $56.4 million, or $5.11 loss per share, for the year ended December 31, 2020.

About ENPP1 Deficiency

ENPP1 Deficiency is a progressive condition that manifests as a spectrum of diseases. Those who present in utero or infancy are typically diagnosed with generalized arterial calcification of infancy (GACI), which is characterized by extensive vascular calcification and neointimal proliferation (overgrowth of smooth muscle cells inside blood vessels), resulting in myocardial infarction, stroke, or cardiac or multiorgan failure. Approximately 45% to 50% of infants with ENPP1 Deficiency die within 6 months of birth. Children and adults with ENPP1 Deficiency typically experience rickets and osteomalacia (softened bones), also termed autosomal-recessive hypophosphatemic rickets type 2 (ARHR2), and can exhibit a range of signs and symptoms that can include hearing loss, arterial calcification, cardiac, and neurological involvement. There are no approved therapies for ENPP1 Deficiency.

About ABCC6 Deficiency

ABCC6 Deficiency is a rare, severe, inherited disorder caused by mutations in the ABCC6 gene, leading to low levels of PPi. PPi is essential for preventing harmful soft tissue calcification and regulating bone mineralization. ABCC6 Deficiency is a systemic and progressively debilitating condition, which we believe affects more than 67,000 individuals worldwide. The condition is characterized by pathological mineralization in blood vessels and soft tissues throughout the body that can drive devastating medical problems. Some infants with ABCC6 Deficiency are diagnosed with generalized arterial calcification of infancy (GACI) type 2, a vascular condition that resembles GACI type 1, the acute infantile form of ENPP1 Deficiency. In older patients, ABCC6 Deficiency presents as pseudoxanthoma elasticum (PXE), a rare, inherited disorder in which individuals develop calcification of soft connective tissues, including in the eyes, cardiovascular system, and skin. There are no approved therapies for ABCC6 Deficiency.

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.

INZ-701 is currently in a Phase 1/2 clinical trial for ENPP1 Deficiency. 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.
