The acquisition will strengthen BioMarin's enzyme therapies portfolio, adding a late-stage enzyme replacement therapy, INZ-701, which is currently being assessed for the treatment of ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) Deficiency, a rare, serious and progressive genetic condition that affects blood vessels, soft tissues and bones. The condition is associated with increased cardiovascular mortality risk across all age groups, especially in infants. It is also associated with severe rickets and osteomalacia in children and adults. Data from the first Phase 3 pivotal study of INZ-701 in children is expected in early 2026, with potential regulatory approval in 2027.

"BioMarin has been deeply committed to advancing enzyme therapies for children and adults living with serious genetic conditions for more than 25 years, and today's agreement builds on our legacy," said Alexander Hardy, President and Chief Executive Officer of BioMarin. "This acquisition brings to BioMarin an important medicine that has the potential to be the first treatment for children and adults with ENPP1 Deficiency, improving care for people living with this serious condition. As BioMarin continues our transformation and delivers on our corporate strategy, we will continue to evaluate external innovation alongside internal innovation. We are in a strong financial position to bring in additional assets as we accelerate the development of medicines for patients with significant unmet need."

"Today's announcement gives greater hope to patients who may benefit from INZ-701, a potentially transformative therapy that aims to address the underlying causes and systemic impacts of ENPP1 Deficiency," said Douglas A. Treco, Ph.D., Chief Executive Officer and Chairman of Inozyme. "BioMarin has paved the way over the past two and a half decades, successfully launching five first-in-disease enzyme therapies. I'd like to thank the team at Inozyme and our partners for their outstanding work and dedication, as we pass this important potentially life-changing therapy to the leading innovator in genetically defined conditions."
