Study reveals ENPP1 deficiency's severe lifetime risks

BOSTON - A comprehensive study published in JBMR Plus has shed light on the serious, lifelong cardiovascular and musculoskeletal complications associated with ENPP1 Deficiency, a rare disease affecting bone health and blood vessel function. The research, conducted by Inozyme Pharma Inc. (NASDAQ: INZY), a clinical-stage biopharmaceutical company currently trading at $0.91 per share with a market capitalization of $58.2 million, in collaboration with global disease experts, represents the largest retrospective analysis of the condition to date. According to InvestingPro data, the company maintains a strong liquidity position with a current ratio of 3.56, indicating sufficient resources to fund its research initiatives.

The study's findings illustrate that ENPP1 Deficiency, which often presents as Generalized Arterial Calcification of Infancy (GACI) or Autosomal Recessive Hypophosphatemic Rickets Type 2 (ARHR2), leads to severe health issues from infancy through adulthood. The analysis of 84 individuals revealed that GACI diagnosis typically occurs at a median age of 0.8 months, with early-onset arterial calcification and cardiovascular complications arising in 60% of patients within the first three months of life.

By the age of 55, over 95% of patients with ENPP1 Deficiency will have experienced significant complications across various organs. Around 70% of patients develop serious musculoskeletal issues by age 10, with rickets severely impacting their quality of life. Additional complications include hearing impairment and ongoing cardiovascular risks.

ENPP1 Deficiency, an autosomal recessive disease, is estimated to occur in approximately 1 in 64,000 pregnancies worldwide. However, the prevalence may be higher as individuals with a single mutated gene also exhibit severe symptoms. Currently, there are no approved therapies for this condition. The company's stock has faced significant challenges, declining 82.71% over the past year, though InvestingPro analysis suggests the stock may be undervalued at current levels.

Inozyme Pharma's lead investigational therapy, INZ-701, is an enzyme replacement therapy designed to address the underlying causes of ENPP1 Deficiency. The company's Senior Vice President and Chief Operating Officer, Matt Winton, Ph.D., emphasized the urgent need for earlier diagnosis and effective treatments to improve long-term outcomes for patients.

Inozyme Pharma is focused on developing treatments targeting the PPi-Adenosine Pathway, a key regulator of bone and blood vessel health. Their pioneering work aims to transform treatment options for patients affected by diseases like ENPP1 Deficiency.
