Jazz Pharma sBLA for M/W/F Rylaze Dosing
Jazz Pharmaceuticals has submitted a Supplemental BLA for a Monday/Wednesday/Friday intramuscular dosing schedule for Rylaze (asparaginase erwinia chrysanthemi (recombinant)-rywn) and its use as a component of a multi-agent chemotherapeutic regimen for treating acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adult and pediatric patients one month and older who have developed hypersensitivity to E. coli-derived asparaginase.
The submission is based on data from the company’s three-cohort intramuscular administration part of the Phase 2/3 trial of Rylaze in adult and pediatric patients with ALL and LBL. “Initial results showed that in cohort 1c, a dosing regimen of Rylaze administered 25 mg/m2 on Monday and Wednesday and 50 mg/m2 on Friday demonstrated a positive benefit-to-risk profile, showing that Rylaze maintains a clinically meaningful level of nadir serum asparaginase activity (NSAA) greater than 0.1 IU/mL at both 48 and 72 hours (from Friday to Monday),” the company says. “In addition, the safety profile of Rylaze was consistent with the reported safety information for patients with ALL/LBL receiving asparaginase with combination chemotherapy.”
