DUBLIN , July 21, 2023 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ ) today announced that the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending the marketing authorization of JZP458 (a recombinant Erwinia asparaginase or crisantaspase) for use as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adult and pediatric patients (1 month and older) who developed hypersensitivity or silent inactivation to E. coli -derived asparaginase.
About Acute Lymphoblastic Leukemia (ALL) Acute lymphoblastic leukemia (ALL) is a cancer of the blood and bone marrow that can progress quickly if not treated. 1,2 ALL is the most common childhood malignancy, accounting for 80% of leukemia diagnoses in children, compared to 20% of adults. 3 Long-term survival rates for pediatric patients have improved significantly over the last few decades. 4 The estimated overall incidence of ALL and lymphoblastic lymphoma (LBL) in Europe is 1.28 per 100,000. 5
Asparaginase is a core component of multi-agent chemotherapeutic regimens in ALL, 6 however, up to 30% of patients develop hypersensitivity to E. coli -derived asparaginase, 7 necessitating treatment discontinuation or a switch to a non- E. coli -derived asparaginase preparation. 8 Patients not receiving asparaginase due to hypersensitivities and those not receiving all prescribed doses have been shown to have poor outcomes. 9,10
About Lymphoblastic Lymphoma (LBL) Lymphoblastic Lymphoma (LBL) is a rare, fast-growing, aggressive subtype of non-Hodgkin's lymphoma (NHL), which is very rare in adults and is most often seen in teenagers and young adults under the age of 35. 11,12 LBL is a type of high-grade lymphoma – which means the lymphoma grows quickly with early spread to different parts of the body. 12 LBL is the second most common type of NHL in childhood and adolescence, accounting for 25-35% of cases. 13
About JZP458 JZP458 is a recombinant Erwinia asparaginase or crisantaspase that uses a Pseudomonas fluorescens expression platform. 9 It is being developed for use as a component of a multi-agent chemotherapeutic regimen in the treatment of pediatric and adult patients with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) who developed hypersensitivity to E. coli -derived asparaginase products. JZP458 was approved by the U.S. Food and Drug Administration (FDA) in June 2021 for the treatment of this patient population and became commercially available in July of the same year in the U.S. 14
