About this study
Official title: An Open-Label, Multicenter Study of Recombinant Crisantaspase Produced in Pseudomonas Fluorescens (RC-P) in Patients With Acute Lymphoblastic Leukemia (ALL)/Lymphoblastic Lymphoma (LBL) Following Hypersensitivity to E. Coli-derived Asparaginases
This is an open-label, multicenter, dose confirmation, and PK study of JZP-458 in patients (of any age) with ALL/LBL who are hypersensitive to E. coli-derived asparaginases (allergic reaction or silent inactivation). This study is designed to assess the tolerability and efficacy of JZP-458 (only in patients who develop hypersensitivity to an E. coli-derived asparaginase), as measured by asparaginase activity.
- Being tested
- IM JZP-458, IV JZP-458
- Keywords
- ALL, LBL, Asparaginase, Leukemia, Childhood acute lymphoblastic leukemia
- Medical subject headings
- Precursor Cell Lymphoblastic Leukemia-Lymphoma, Leukemia
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IM JZP-458Drug
IM JZP-458 will be administered in Part A, Cohorts 1 \& 2
IV JZP-458Drug
IV JZP-458 will be administered in Part B
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Drug: IM JZP-458; Drug: IV JZP-458 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Response Rate During the First Course of JZP-458 Administration
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.
Measured: Baseline up to 2 weeks
Number of Participants With Any Treatment-emergent Adverse Events (TEAEs)
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.
Measured: Date of written informed consent up to 30 days after last dose of last course, up to approximately 2 years 7 months
Secondary outcomes (4)
Number of Participants With Last 48-hour NSAA Level ≥ 0.1 IU/mL During The First Course (6 Doses) of JZP-458 Administration
Blood samples were collected for serum asparaginase activity level determination.
Measured: Baseline up to 2 weeks
Number of Participants With Last NSAA Levels ≥ 0.4 IU/mL During The First Course (6 Doses) of JZP-458 Administration
Blood samples were collected for serum asparaginase activity level determination.
Measured: Baseline up to 2 weeks
Mean Serum Asparaginase Activity Levels in First Course of JZP-458 Administration
Serum asparaginase levels serve as a surrogate marker for asparagine depletion. Mean serum asparaginase activity levels in Course 1 are reported.
Measured: Up to 2 weeks (6 doses)
Number of Participants Who Are Anti-drug Antibody Positive or Negative Against JZP-458
Blood samples were collected for immunogenicity analysis. Anti-drug antibody positive (ADA+) participants were those with a positive result on the first test and also a positive result on the confirmatory test. Anti-drug antibody negative (ADA-) participants had a negative result on the first test.
Measured: Baseline up to 30 days (ADA- samples) after last dose of last course and up to 6 months (ADA+ samples) after last dose of last course, up to approximately 2 years 7 months

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing IM JZP-458 and IV JZP-458 in people with Acute Lymphoblastic Leukemia and Lymphoblastic Leukemia, run by Jazz Pharmaceuticals at 74 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 74 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Nov 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Response Rate During the First Course of JZP-458 Administration (time frame: Baseline up to 2 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04145531, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2023.
