The response rate was defined as the number (proportion) of patients with the last 72-hour nadir serum asparaginase activity (NSAA) level ≥ 0.1 IU/mL during the first course of IM JZP-458. Blood samples were collected for serum asparaginase activity level determination.
An adverse event (AE) is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered related to study drug. AEs were classified by the Investigator using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.

| JZP-458 | EXPERIMENTAL | Part A (IM JZP-458) of the study will have 2 IM cohorts: * Cohort 1: a JZP-458 repeat dose/confirmatory cohort; a final IM JZP-458 dose level will be selected, and * Cohort 2: an expansion cohort to confirm the efficacy and safety of the final IM JZP-458 dose level and schedule Part B (IV JZP-458 Dose Confirmation) will be conducted to define the optimal dose of the IV administration of JZP-458 for further study in ALL/LBL patients as a repeated dose. Additional courses of JZP-458 (IM or IV depending on patient's allocation at study enrollment) will be administered based on each patient's original treatment plan for as long as the patient derives clinical benefit. |
