BOSTON, May 07, 2024 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (NASDAQ:INZY) ("the Company" or "Inozyme"), 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 first quarter ended March 31, 2024, and provided business highlights.
"We were extremely pleased to see preliminary evidence of improved vascular health with INZ-701 treatment in adults with ABCC6 Deficiency, providing strong support for further clinical development in this disease," said Douglas A. Treco, Ph.D., CEO and Chairman of Inozyme. "We found that children with ABCC6 Deficiency are at high risk for neurological and visual impairment and represent the most pressing unmet need in this disease, substantially expanding the addressable population beyond impacted adults. We look forward to working with regulators to establish a path to approval for our ABCC6 Deficiency program, as well as presenting additional data from current trials in our calciphylaxis and ENPP1 Deficiency programs."
Recent Highlights
- Phase 1/2 Clinical Trial of INZ-701 in Adults with ABCC6 Deficiency. In April 2024, the Company announced positive topline safety and immunogenicity data, with clinical improvements in vascular pathology, visual function, and patient reported outcomes (PROs).
- Natural History Studies and Development Plans for INZ-701 in Pediatric ABCC6 Deficiency. In April 2024, the Company reported initial findings from natural history studies which indicate a substantial disease burden among pediatric patients with ABCC6 Deficiency, manifesting as a high incidence of major clinical events, notably stroke, severe neurological disease, and severe cardiovascular disease, occurring early in life. Subject to regulatory review and sufficient funding, the Company expects to initiate a pivotal trial in pediatric patients with ABCC6 Deficiency in Q1 2025.
- Phase 1/2 Clinical Trial of INZ-701 in Adults with ENPP1 Deficiency. In April 2024, the Company announced positive topline data indicating that the previously-reported favorable safety, immunogenicity, and clinical outcome data were maintained through 48 weeks in Cohorts 1-3. Data from Cohort 4 support once weekly dosing in ongoing and future clinical trials.

- Net Loss. Net loss was $23.3 million, or $0.38 loss per share, for the quarter ended March 31, 2024, compared to $17.4 million or $0.40 loss per share for the prior-year period.
About ABCC6 Deficiency
ABCC6 Deficiency is a progressively debilitating condition of the vasculature and soft tissue that is estimated to affect approximately 1 in 25,000 to 1 in 50,000 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. Pediatric patients who survive the first year of life may develop neurological disease, including stroke, and cardiovascular disease secondary to ongoing vascular calcification and stenosis. In older individuals, ABCC6 Deficiency presents as pseudoxanthoma elasticum (PXE), which is characterized by pathologic mineralization in blood vessels and soft tissues clinically affecting the skin, eyes, and vascular system. There are no approved therapies for ABCC6 Deficiency.
About ENPP1 Deficiency
ENPP1 Deficiency is a progressively debilitating condition of the vasculature, soft tissue, and skeleton with a prevalence of approximately 1 in 64,000 pregnancies worldwide. Although ENPP1 Deficiency was initially described in patients with biallelic ENPP1 Deficiency (homozygous or compound heterozygous mutations), many patients with monoallelic ENPP1 Deficiency (heterozygous mutations) have clinical symptoms, potentially increasing the worldwide prevalence. Individuals who present in utero or in infancy are typically diagnosed with generalized arterial calcification of infancy (GACI Type 1) and approximately 50% of infants 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 Calciphylaxis
Calciphylaxis is a rare disorder with a high mortality rate that mostly affects patients with end-stage kidney disease (ESKD). The disease is associated with low levels of pyrophosphate (PPi) and is characterized by pathologic mineralization (i.e., calcification) and intimal proliferation (the overgrowth of smooth muscle cells inside blood vessels) of the vasculature in the skin and fatty tissue leading to poor blood flow, blood clots, painful skin ulcers, serious infections, and death. Patients with calciphylaxis have a reported one-year survival rate of approximately 50%. The estimated incidence of calciphylaxis is approximately 3.5 per 1,000 patients with ESKD with approximately 5,000 new patients presenting annually across major geographies. There are no approved therapies for calciphylaxis.
About INZ-701
INZ-701, a recombinant Fc fusion protein, is an ENPP1 enzyme replacement therapy (ERT) in development for the treatment of rare disorders of the vasculature, soft tissue, and skeleton. INZ-701 metabolizes adenosine triphosphate (ATP) to generate PPi, a natural inhibitor of mineralization, and AMP, which can be processed to phosphate and adenosine, the latter being a natural inhibitor of intimal proliferation. In preclinical studies, the experimental therapy has shown potential to prevent pathologic mineralization and intimal proliferation, which can drive morbidity and mortality in devastating disorders such as, ENPP1 Deficiency, ABCC6 Deficiency, and calciphylaxis. Clinical data to date have demonstrated that INZ-701 was generally well tolerated, exhibited a favorable safety profile, and meaningfully increased PPi levels in multiple clinical trials.
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. INZ-701 is currently in clinical development for the treatment of ENPP1 Deficiency, ABCC6 Deficiency, and calciphylaxis.
