(Nasdaq: INZY) (“Inozyme” or “Company”), a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of pathologic mineralization and intimal proliferation, today reported financial results for the second quarter ended June 30, 2023, and provided business highlights. “We continue to make tremendous progress advancing our clinical programs of INZ-701 in patients with ENPP1 Deficiency and ABCC6 Deficiency, with interim data from both programs expected in September 2023,” said Douglas A. Treco, Ph.D., chief executive officer and chairman of Inozyme’s board of directors. “Notably, following regulatory discussions with the FDA and EMA, we have outlined a clear path forward toward supporting potential regulatory filings in ENPP1 Deficiency.” Recent Clinical Highlights Global Development Strategy Update for INZ-701 in Patients with ENPP1 Deficiency. In July 2023, Inozyme announced that based on guidance from the U.S. Food and Drug Administration (FDA) and the Paediatric Committee (PDCO) of the European Medicines Agency (EMA), change in plasma PPi will serve as the primary endpoint in the U.S., supported by consistent trends in appropriate secondary endpoints, and a co-primary endpoint in the EU for the ENERGY-3 pivotal trial in pediatric patients. Based on regulatory feedback from the FDA and EMA, positive data from the ongoing and planned clinical trials of INZ-701 in patients with ENPP1 Deficiency, including comprehensive data demonstrating clinical impact of plasma PPi, could provide the basis for the Company’s submission of marketing applications in both the U.S. and EU. These data will include final results from the ongoing Phase 1/2 trial in adults, available results from the ongoing ENERGY-1 Phase 1b and planned ENERGY-2 pivotal trial in infants, and final results from the planned ENERGY-3 pivotal trial in pediatric patients. If these marketing applications are approved, the Company expects to commercially launch INZ-701 for infant and pediatric patients as early as the second half of 2026. Pending regulatory discussions and appropriate financial resources, the Company also plans to conduct the ENERGY-4 pivotal trial in adolescents and adults with ENPP1 Deficiency. Data from the planned ENERGY-4 trial may provide the basis for supplemental marketing applications. ENERGY-1 Phase 1b Trial of INZ-701 in Infants with ENPP1 Deficiency. Dosing is now underway in the Phase 1b ENERGY-1 trial designed to primarily assess the safety, tolerability, pharmacokinetic, and pharmacodynamic pro INZ-701 in infants with ENPP1 Deficiency. Medical Conference Presentations. In the second quarter, Yves Sabbagh, Ph.D., Inozyme’s senior vice president and chief scientific officer, and Kurt Gunter, M.D., Inozyme’s senior vice president and chief medical officer, presented previously reported interim data from the ongoing Phase 1/2 clinical trial of INZ-701 in patients with ENPP1 Deficiency at the European Calcified Tissue Society Congress and European Congress of Endocrinology, respectively. Recent Corporate Highlights Closed Underwritten Offering. In August 2023, the Company closed an underwritten public offering of 14,375,000 shares of its common stock at a price of $4.80 per share, for net proceeds of approximately $64.5 million from the offering, after deducting underwriting discounts and commissions and estimated offering expenses. Anticipated Milestones ENPP1 Deficiency Interim data from Cohorts 1-3 in the Phase 2 portion of the ongoing Phase 1/2 trial in adults – Sep. 2023 Initiation of the ENERGY-3 pivotal trial in pediatric patients – Oct. 2023 Topline data from Cohorts 1-3 in the ongoing Phase 1/2 trial in adults – Q1 2024 Initiation of the ENERGY-2 pivotal trial in infants, ex-U.S. – Q2 2024 Interim data from the ENERGY-1 Phase 1b trial in infants – 2H 2024 Topline data from the ENERGY-3 pivotal trial in pediatric patients – Mid-2025 ABCC6 Deficiency Interim data from the Phase 2 portion of the ongoing Phase 1/2 trial in adults – Sep. 2023 Topline data from the Phase 2 portion of the ongoing Phase 1/2 trial in adults – Q1 2024 Initiation of Phase 2 clinical trial of INZ-701 in adult patients with ABCC6 Deficiency, subject to regulatory review and sufficient funding – Q4 2024 Second Quarter 2023 Financial Results Cash Position and Financial Guidance. Cash, cash equivalents, and short-term investments were $140.2 million as of June 30, 2023. Based on its current plans, the Company now anticipates its cash, cash equivalents, and short-term investments as of June 30, 2023, together with approximately $64.5 million in proceeds from the July 2023 public offering, will enable the Company to fund its cash flow requirements into Q4 2025. Research and Development (R&D) Expenses. R&D expenses were $11.7 million for the quarter ended June 30, 2023, compared to $10.0 million for the prior-year period. This increase was primarily due to increased chemistry, manufacturing, and controls expenses, clinical development costs, and personnel-related expenses to support our clinical trials. General and Administrative (G&A) Expenses. G&A expenses were $4.7 million for the quarter ended June 30, 2023, compared to $5.4 million for the prior-year period. The decrease was primarily related to a decrease in stock-based compensation expense and cost-saving initiatives. Net Loss. Net loss was $15.6 million, or $0.35 loss per share, for the quarter ended June 30, 2023, compared to $15.3 million, or $0.38 loss per share, for the prior-year period. About ENPP1 Deficiency ENPP1 Deficiency is a progressive condition that manifests as a spectrum of diseases. Individuals who present in utero or in infancy are typically diagnosed with generalized arterial calcification of infancy (GACI), which is characterized by extensive vascular calcification and intimal proliferation (overgrowth of smooth muscle cells inside blood vessels), resulting in myocardial infarction, stroke, or cardiac or multiorgan failure. Approximately 50% of infants with ENPP1 Deficiency die within six months of birth. Children with ENPP1 Deficiency typically develop rickets, a condition diagnosed as autosomal-recessive hypophosphatemic rickets type 2 (ARHR2), while adolescents and adults can develop osteomalacia (softened bones). ARHR2 and osteomalacia lead to pain and mobility issues. Patients can also exhibit signs and symptoms of hearing loss, arterial and joint calcification, and cardiovascular complications. 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 affects more than 67,000 individuals worldwide. Infants with ABCC6 Deficiency are diagnosed with generalized arterial calcification of infancy (GACI) type 2, a condition that resembles GACI type 1, the infant form of ENPP1 Deficiency. In older individuals, ABCC6 Deficiency presents as pseudoxanthoma elasticum (PXE), which is characterized by pathological mineralization in blood vessels and soft tissues clinically affecting the skin, eyes, and vascular system. There are no approved therapies for ABCC6 Deficiency. About INZ-701 INZ-701, a recombinant Fc fusion protein, is an ENPP1 enzyme replacement therapy in development for the treatment of rare disorders of the vasculature, soft tissue, and skeleton. In preclinical studies, the experimental therapy has shown potential to prevent pathologic mineralization and intimal proliferation (the overgrowth of smooth muscle cells inside blood vessels), which can drive morbidity and mortality in devastating genetic disorders such as ENPP1 Deficiency and ABCC6 Deficiency. INZ-701 is currently in clinical trials for the treatment of ENPP1 Deficiency and ABCC6 Deficiency. About Inozyme Pharma Inozyme Pharma, Inc. is a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of diseases impacting the vasculature, soft tissue and skeleton. Inozyme is developing INZ-701, an enzyme replacement therapy, to address pathologic mineralization and intimal proliferation which can drive morbidity and mortality in these severe diseases.

- Change in plasma pyrophosphate (PPi) as primary endpoint in the U.S. and co-primary endpoint in the EU for planned ENERGY-3 pivotal trial in pediatric patients - - ENERGY-3 pivotal trial in pediatric patients expected to initiate in October 2023, topline data expected to be reported in mid-2025 - - Updated cash runway expected to fund cash flow requirements into Q1 2025 - - Company to host conference call today at 8am ET - BOSTON, July 26, 2023 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (Nasdaq: INZY) (“Inozyme” or the “Company”), a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of pathologic mineralization and intimal proliferation, today announced a regulatory update for its global development strategy of INZ-701 for the treatment of ENPP1 Deficiency following recent meetings with the United States (U.S.) Food and Drug Administration (FDA) and the Paediatric Committee (PDCO) of the European Medicines Agency (EMA). “We are pleased to have finalized our pediatric pivotal trial design with PPi, a well-established natural inhibitor of mineralization, as a primary endpoint in the U.S. and a co-primary endpoint in the EU. We have already observed that INZ-701 meaningfully increased PPi levels in our ongoing trial of INZ-701 in adults with ENPP1 Deficiency and, based on our discussions with regulators in the U.S. and EU, we believe we have a clear path forward in our clinical development program for the treatment of ENPP1 Deficiency,” said Douglas A. Treco, Ph.D., CEO of Inozyme Pharma. ENERGY-3 Trial Design – Planned Pivotal Trial in Pediatric Patients with ENPP1 Deficiency The Company plans to initiate the ENERGY-3 pivotal trial, a multicenter, randomized, open label trial in pediatric patients with ENPP1 Deficiency in October 2023. The ENERGY-3 trial is expected to enroll up to 33 patients between the ages of one and less than 13 years across multiple sites globally and is designed primarily to assess the efficacy and safety of INZ-701 in pediatric patients with ENPP1 Deficiency. Enrollment criteria for the trial include a confirmed genetic diagnosis of ENPP1 Deficiency, radiographic evidence of skeletal abnormalities and low plasma PPi. Patients will be randomized in a 2:1 ratio to an INZ-701 arm or a control arm (conventional therapy, i.e., oral phosphate and active vitamin D) for 52 weeks, followed by an open label extension period during which all patients may receive INZ-701. INZ-701 will be administered at a 2.4 mg/kg once weekly dose via subcutaneous (SC) injection. ENERGY-3 is a single, multicenter, clinical trial with differences in the statistical treatment of endpoints, based on guidance from the FDA and PDCO, as follows: U.S.EUPrimary Endpoint – Change in plasma PPi from baselineCo-Primary Endpoints – Change in plasma PPi from baseline and Radiographic Global Impression of Change (RGI-C) score (p<0.2)Secondary Endpoints - RGI-C score, Rickets Severity Score (RSS), Growth Z-score and pharmacokinetics (PK)Secondary Endpoints – RSS, Growth Z-score and PK Based on recommendations from the FDA, the primary endpoint of plasma PPi should be supported by consistent trends in appropriate secondary endpoints. Based on the agreed Paediatric Investigational Plan (PIP) with PDCO, plasma PPi and RGI-C are co-primary endpoints, with a relaxed p-value of <0.2 for RGI-C. Planned Pivotal Trials in Infants and Adolescent/Adult Patients with ENPP1 Deficiency The Company plans to conduct the ENERGY-2 pivotal trial, an open label, single arm trial in infants with ENPP1 Deficiency, based on the Paediatric Investigational Plan (PIP) agreed upon by PDCO. The trial is expected to be initiated outside of the U.S. The trial’s co-primary endpoints will be change in plasma PPi from baseline and survival. The trial is expected to enroll up to 12 infants between birth and up to 12 months of age. Primary endpoint data from this trial will be compared to a natural history control group with patients matched on covariates associated with mortality. Discussions are ongoing with the FDA regarding the design of a potential pivotal trial of INZ-701 in infants with ENPP1 Deficiency in the U.S. Pending regulatory discussions and appropriate financial resources, the Company also plans to conduct the ENERGY-4 pivotal trial, a multicenter, randomized, controlled trial in adolescents and adults with ENPP1 Deficiency. In the U.S., the trial’s sole primary endpoint is expected to be change in plasma PPi from baseline, supported by trends in appropriate secondary endpoints, and in the EU, the trial’s co-primary endpoints are expected to be change in plasma PPi from baseline and bone mineral content/density. Subject to regulatory review, the trial is expected to enroll up to 30 patients 13 years and older, and patients will be randomized in a 2:1 ratio to an INZ-701 arm or a control arm (conventional therapy, i.e., oral phosphate and active vitamin D). Basis for Planned Marketing Applications Based on regulatory feedback from the FDA and EMA, positive data from the ongoing and planned clinical trials of INZ-701 in patients with ENPP1 Deficiency, including comprehensive data demonstrating clinical impact of plasma PPi, could provide the basis for the Company’s submission of marketing applications in both the U.S. and EU. These data will include final results from the Company’s ongoing Phase 1/2 trial in adult patients with ENPP1 Deficiency, available results from the Company’s ongoing ENERGY-1 trial, a Phase 1b trial of INZ-701 in infants with ENPP1 Deficiency, available results from the planned pivotal ENERGY-2 trial in infants to be initiated ex-U.S., and final results from the planned pivotal ENERGY-3 trial in pediatric patients. If these marketing applications are approved, the Company expects to commercially launch INZ-701 for infant and pediatric patients as early as the second half of 2026. Data from the planned ENERGY-4 trial in adolescent and adult patients with ENPP1 Deficiency may provide a basis for a supplemental marketing application. Anticipated Milestones for ENPP1 Deficiency Program Interim data from Cohorts 1-3 in the Phase 2 portion of the ongoing Phase 1/2 trial in adults – September 2023Initiation of ENERGY-3 trial, a pivotal trial in pediatric patients – October 2023Topline data from Cohorts 1-3 in the Phase 2 portion of the ongoing Phase 1/2 trial in adults – Q1 2024Initiation of ENERGY-2 trial, a pivotal trial in infants, ex U.S. - Q2 2024Interim data from ENERGY-1 trial, a Phase 1b trial in infants – 2H 2024Topline data from ENERGY-3 trial, a pivotal trial in pediatric patients – Mid-2025 Cash Runway Guidance The Company expects to report cash, cash equivalents, and short-term investments of approximately $140.2 million as of June 30, 2023. The estimated cash, cash equivalents, and short-term investments amount is preliminary and unaudited, represents management’s estimate as of the date of this press release, is subject to completion of the Company’s financial closing procedures for the quarter ended June 30, 2023 and does not present all necessary information for a complete understanding of the Company’s financial condition as of June 30, 2023, or the Company’s results of operations for the quarter ended June 30, 2023. The actual financial results may differ materially from the preliminary estimated financial information. Based on its current plans, the Company anticipates its cash, cash equivalents, and short-term investments as of June 30, 2023, will enable the Company to fund cash flow requirements into the first quarter of 2025.
