Inozyme Pharma Raises $49 Million in a Series A Financing to Develop Therapies for Rare Diseases Affecting Soft Tissues and Bone

Company bolsters leadership team with several executive appointments

CAMBRIDGE, Mass.--()--Inozyme Pharma, Inc., a biotechnology company developing novel medicines to treat rare diseases of calcification, affecting soft tissues and bone, today announced it has raised a $49 million Series A financing. The financing was led by Longitude Capital, and included participation from New Enterprise Associates (NEA), Novo Ventures and Sanofi Ventures.

“Our mission is to develop potentially disease-modifying therapies to help children who are affected with rare, but severe and debilitating disorders of metabolism. These patients have very poor treatment options,” said Axel Bolte, chief executive officer and co-founder of Inozyme Pharma. “We have attracted a premier syndicate of healthcare investors who are committed to helping us achieve our goal, and this funding positions us well to advance our therapeutic approach.”

Inozyme Pharma was founded in 2016 with technology developed in the laboratory of Demetrios Braddock, M.D., Ph.D., and licensed from Yale University. The company will use the proceeds from this financing to advance its lead enzyme replacement therapy for the treatment of Generalized Arterial Calcification of Infancy (GACI) and Autosomal Recessive Hypophosphatemic Rickets Type 2 (ARHR2) into the clinic. These disorders are characterized by mineral imbalances that lead to over calcification of soft tissues and under mineralization of bone.

“Inozyme Pharma’s deep understanding of the biology of calcification will be used to develop new medicines that have the potential to drastically improve the standard-of-care,” said Reinaldo Diaz, venture partner at Longitude Capital, and a member of Inozyme Pharma’s board of directors. “With strong foundational intellectual property and a multidisciplinary team of experts, the company is well-positioned to advance new therapies for underserved populations.”

About GACI and ARHR2

GACI is an ultra-rare, autosomal recessive orphan disease affecting infants. It is caused by loss-of-function mutations in either the ENPP1 or ABCC6 gene, and results in low circulating levels of pyrophosphate (PPi) and calcification of medium and large arteries and heart. GACI presents as a crisis within the first week of life and is associated with high mortality rates. The majority of patients are likely to die within the first year of life. If affected children survive past six months, they are likely to continue living but develop ARHR2, a rare skeletal disorder characterized by low levels of serum PPi, which can result in rickets, repeated fractures of the long bones, rachitic skeletal deformities, and impaired growth and development.
