Trial Summary

What is the purpose of this trial?This trial is testing Calaspargase pegol, a medication for treating a specific type of blood cancer called Philadelphia-negative Acute Lymphoblastic Leukemia. The study aims to find the best dose and check the safety of the drug. Calaspargase pegol works by starving the cancer cells of a nutrient they need to survive.
Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have had prior therapy for ALL, except for limited corticosteroids or hydroxyurea treatment and a single dose of intrathecal cytarabine.

What data supports the idea that Calaspargase Pegol for Acute Lymphoblastic Leukemia is an effective drug?

The available research shows that Calaspargase Pegol is effective in treating Acute Lymphoblastic Leukemia (ALL) in children and young adults. It was approved by the FDA based on its ability to maintain necessary enzyme levels in the blood, which is crucial for successful treatment. In a study, 99% of patients maintained these levels over several weeks, indicating its effectiveness. Additionally, when compared to another drug, Pegaspargase, Calaspargase Pegol had a similar safety profile and did not negatively impact the patients' chances of staying free from the disease.

Efficacy and Toxicity of Pegaspargase and Calaspargase Pegol in Childhood Acute Lymphoblastic Leukemia: Results of DFCI 11-001. [2021]Dana-Farber Cancer Institute Acute Lymphoblastic Leukemia (ALL) Consortium Protocol 11-001 assessed efficacy and toxicity of calaspargase pegol (calaspargase), a novel pegylated asparaginase formulation with longer half-life, compared with the standard formulation pegaspargase.
Pharmacokinetic and pharmacodynamic properties of calaspargase pegol Escherichia coli L-asparaginase in the treatment of patients with acute lymphoblastic leukemia: results from Children's Oncology Group Study AALL07P4. [2021]Asparaginase is a critical agent used to treat acute lymphoblastic leukemia (ALL). Pegaspargase (SS-PEG), a pegylated form of Escherichia coli L-asparaginase with a succinimidyl succinate (SS) linker, is the first-line asparaginase product used in Children's Oncology Group (COG) ALL trials. Calaspargase pegol (SC-PEG) replaces the SS linker in SS-PEG with a succinimidyl carbamate linker, creating a more stable molecule. COG AALL07P4 was designed to determine the pharmacokinetic and pharmacodynamic comparability of SC-PEG to SS-PEG in patients with newly diagnosed high-risk (HR) B-cell ALL.
FDA Approval Summary: Calaspargase Pegol-mknl For Treatment of Acute Lymphoblastic Leukemia in Children and Young Adults. [2020]On December 20, 2018, the Food and Drug Administration approved calaspargase pegol-mknl (CALASP), an asparagine-specific enzyme, as a component of a multi-agent chemotherapeutic regimen for acute lymphoblastic leukemia (ALL) in pediatric and young adult patients age 1 month to 21 years. Efficacy was determined on the basis of achievement and maintenance of steady-state nadir serum asparaginase activity (NSAA) above 0.1 U/mL when using CALASP, 2,500 U/m2 intravenously, every 3 weeks. In a randomized comparison to pegaspargase (PEGASP) every 2 weeks, treatment with CALASP every 3 weeks had a similar safety profile and no substantial impairment in event-free survival. The pharmacokinetics of CALASP were studied when administered in combination with multiagent chemotherapy in 124 patients with B-cell ALL in Study AALL07P4 and Study DFCI 11-001. The results showed that 123 [99%, 95% confidence interval (CI), 96%-100%] of the 124 patients maintained NSAA >0.1 U/mL at weeks 6, 12, 18, 24, and 30 of post-induction phase. Maintaining adequate NSAA levels is critical to successful treatment of ALL. Herein, we describe the FDA review and approval of CALASP.See related commentary by Lew, p. 325.
Space for Calaspargase? A New Asparaginase for Acute Lymphoblastic Leukemia. [2020]In December 2018, the FDA approved calaspargase pegol-mknl (Asperlas, Servier Pharmaceuticals) for acute lymphoblastic leukemia (ALL) in children and young adults up to age 21. Asparaginase is a critical component in the treatment of ALL, but the niche for calaspargase within current treatment protocols is unclear.See related article by Li et al., p. 328.
Effective asparagine depletion with pegylated asparaginase results in improved outcomes in adult acute lymphoblastic leukemia: Cancer and Leukemia Group B Study 9511. [2021]CALGB 9511 used pegaspargase (PEG-ASP) in lieu of the native enzyme. The aim was to compare differences in overall survival (OS) and disease-free survival (DFS) between patients who did and did not achieve asparagine depletion, defined by enzyme levels greater than 0.03 U/mL plasma for 14 consecutive days after at least 1 of 4 planned PEG-ASP administrations. Samples were available from 85 eligible patients. On univariate analyses, the 22 patients who did not achieve asparagine depletion had inferior OS (P = .002; hazard ratio [HR] = 2.37; 95% CI = 1.38-4.09) and DFS (P = .012; HR = 2.21; 95% CI = 1.19-4.13). After adjusting for age, performance status, leukocyte count, and karyotype in a proportional hazards model, both the OS and DFS HRs decreased to 1.8 (P = .056; 95% CI = 1.0-3.2 and P = .084; 95% CI = 0.9-3.6, respectively). We conclude that effective asparagine depletion with PEG-ASP is feasible as part of an intensive multiagent therapeutic regimen in adult acute lymphoblastic leukemia and appears associated with improved outcomes.
Experience with generic pegylated L-asparaginase in children with acute lymphoblastic leukemia and monitoring of serum asparaginase activity. [2019]Pegylated asparaginase (P-Asp) though integral to acute lymphoblastic leukemia (ALL) therapy is often not accessible to patients in developing countries. We share our clinical experience with generic P-Asp along with monitoring of asparaginase activity.
Intravenous pegylated asparaginase versus intramuscular native Escherichia coli L-asparaginase in newly diagnosed childhood acute lymphoblastic leukaemia (DFCI 05-001): a randomised, open-label phase 3 trial. [2022]l-asparaginase is a universal component of treatment for childhood acute lymphoblastic leukaemia, and is usually administered intramuscularly. Pegylated Escherichia coli asparaginase (PEG-asparaginase) has a longer half-life and is potentially less immunogenic than the native Escherichia coli (E coli) preparation, and can be more feasibly administered intravenously. The aim of the Dana-Farber Cancer Institute Acute Lymphoblastic Leukaemia Consortium Protocol 05-001 (DFCI 05-001) was to compare the relative toxicity and efficacy of intravenous PEG-asparaginase and intramuscular native E colil-asparaginase in children with newly diagnosed acute lymphoblastic leukaemia.
