BOSTON, May 12, 2021 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (Nasdaq: INZY), a rare disease biopharmaceutical company developing novel therapeutics for the treatment of abnormal mineralization, today reported financial results for the first quarter ended March 31, 2021 and provided recent business highlights.

“We closed 2020 with the clearance of our IND for INZ-701 by the FDA and our CTA by the MHRA of the UK, both for ENPP1 Deficiency. Since then, we have continued to execute on our plan to deliver a potential therapeutic option for patients with ENPP1 and ABCC6 Deficiencies,” said Axel Bolte, MSc, MBA, co-founder, president, and chief executive officer of Inozyme Pharma. “We recently reported key findings from the Burden of Illness Study in patients with both ENPP1 Deficiency and ABCC6 Deficiency. Notably, we found patients in different age groups are impacted by these deficiencies in distinct ways, illuminating an age-based shift that reflects the progression of these debilitating genetic diseases. We expect site activation in the United States for our Phase 1/2 clinical trial site for ENPP1 Deficiency in June 2021 and enrollment of the first patient shortly thereafter. Subject to receiving regulatory clearance, we also expect to initiate our planned Phase 1/2 clinical trial of INZ-701 for ABCC6 Deficiency in mid-2021.”

Mr. Bolte continued, “Our current cash position allows us to appropriately resource each of the key functions necessary to execute on our goals, and is expected to enable our operations into the fourth quarter of 2022.”

Recent Business Highlights

• Filed Clinical Trial Application for INZ-701 for ABCC6 Deficiency in Europe – The Company expects to initiate a Phase 1/2 clinical trial in mid-2021 and to provide preliminary safety and biomarker data by the end of 2021.
• Published data supporting INZ-701 as a potential treatment for ENPP1 Deficiency – Peer-reviewed article in the Journal of Bone and Mineral Research shows INZ-701 increased plasma pyrophosphate (PPi) levels, improved disease markers, and decreased mortality in an Enpp1-deficient mouse model. Preclinical findings support increase of PPi levels as a predictive marker of therapeutic benefit.
• Data presented on utility of INZ-701 as a potential treatment for ABCC6 Deficiency – The Company and research collaborators from Thomas Jefferson University presented data from a preclinical study examining INZ-701 for the potential treatment for ABCC6 Deficiency/Pseudoxanthoma elasticum (PXE) at multiple medical conferences.
• Data presented from Burden of Illness Study for ENPP1 and ABCC6 Deficiencies – The Company presented data from the first-ever burden of illness study in patients with ENPP1 and ABCC6 Deficiencies at multiple medical conferences.

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
  • June 2021: Site activation for Phase 1/2 clinical trial
  • Mid-2021: Enrollment for Phase 1/2 clinical trial
  • Mid-2021: Initiate prospective natural history study
  • H2 2021: Report preliminary safety and biomarker data from Phase 1/2 clinical trial
• ABCC6 Deficiency
  • Mid-2021: Site activation and enrollment for 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 Quarter Ended March 31, 2021

• Cash Position and Financial Guidance – Cash, cash equivalents, and investments were $147.6 million as of March 31, 2021. 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 fourth quarter of 2022.
• Research and Development (R&D) Expenses – R&D expenses were $6.6 million for the quarter ended March 31, 2021, compared to $6.4 million for the quarter ended March 31, 2020. The increase was primarily due to costs associated with preclinical studies and clinical preparation activities with the Company’s contract research organization and increased salaries and employee-related costs due to the growth in the number of R&D employees.
• General and Administrative (G&A) Expenses – G&A expenses were $4.4 million for the quarter ended March 31, 2021, compared to $1.5 million for the quarter ended March 31, 2020. 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 $11.1 million, or $0.47 loss per share, for the quarter ended March 31, 2021, compared to $7.7 million, or $6.42 loss per share, for the quarter ended March 31, 2020.

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.
