On September 21, 2023, it was announced that JZP458 received approval from the European Commission for use in a multi-agent chemotherapy treatment in adult and pediatric patients (≥1 month) with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL), who have developed silent inactivation or hypersensitivity to E.Coli derived asparaginase.
JZP458 is an Erwina-derived asparaginase that was developed with next-generation recombinant technology and has a safety profile consistent with other asparaginase therapies. The approval is based on data from JZP458-201 (NCT04145531), a phase II/III clinical trial investigating JZP458 chemotherapeutic regimen in 228 patients with ALL or LBL with sensitivity or inactivated E.Coli-derived asparaginase.
