The European Commission has granted marketing authorization for pegaspargase (Oncaspar) to be used as part of combination antineoplastic therapy for pediatric and adult patients with acute lymphoblastic leukemia (ALL).
The approval means the drug can be marketed for this indication in the 28 member countries of the European Union (EU), as well as Iceland, Liechtenstein, and Norway.
Pegaspargase was already approved for use in Argentina, Belarus, Germany, Kazakhstan, Poland, Russia, Ukraine, and the US.
“Oncaspar has been used as an integral component of the treatment regimen for pediatric and adult patients with ALL for many years, in Europe and worldwide,” said Martin Schrappe, of Schleswig-Holstein University Hospital in Kiel, Germany.
“Today’s marketing authorization will ensure that more patients across the EU will benefit from access to Oncaspar as part of a standard of care regimen.”
The drug is being developed by Baxalta Incorporated.
First-line ALL
Researchers have evaluated the safety and effectiveness of pegaspargase in a study of 118 pediatric patients (ages 1 to 9) with newly diagnosed ALL. The patients were randomized 1:1 to pegaspargase or native E coli L-asparaginase, both as part of combination therapy.
Asparagine depletion (magnitude and duration) was similar between the 2 treatment arms. Event-free survival rates were also similar (about 80% in both arms), but the study was not designed to evaluate differences in event-free survival.
Grade 3/4 adverse events occurring in the pegaspargase and native E coli L-asparaginase arms, respectively, were abnormal liver tests (5% and 8%), elevated transaminases (3% and 7%), hyperbilirubinemia (2% and 2%), hyperglycemia (5% and 3%), central nervous system thrombosis (3% and 3%), coagulopathy (2% and 5%), pancreatitis (2% and 2%), and clinical allergic reactions to asparaginase (2% and 0%).
Previously treated ALL
Researchers have evaluated the effectiveness of pegaspargase in 4 open-label studies of patients with a history of prior clinical allergic reaction to asparaginase. The studies enrolled a total of 42 patients with multiply relapsed acute leukemia (39 with ALL).
Patients received pegaspargase as a single agent or as part of multi-agent chemotherapy. The re-induction response rate was 50%—36% complete responses and 14% partial responses. Three responses occurred in patients who received single-agent pegaspargase.
Adverse event information on pegaspargase in relapsed ALL has been compiled from 5 clinical trials. The studies enrolled a total of 174 patients with relapsed ALL who received pegaspargase as a single agent or as part of combination therapy.
Sixty-two of the patients had prior hypersensitivity reactions to asparaginase, and 112 did not. Allergic reactions to pegaspargase occurred in 32% of previously hypersensitive patients and 10% of non-hypersensitive patients.
The most common adverse events observed in patients who received pegaspargase were clinical allergic reactions, elevated transaminases, hyperbilirubinemia, and coagulopathies.
The most common serious adverse events due to pegaspargase were thrombosis (4%), hyperglycemia requiring insulin therapy (3%), and pancreatitis (1%).
