The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) is recommending marketing authorization for lyophilized pegaspargase (ONCASPAR).
If approved, the product would be used as a component of antineoplastic therapy in patients of all ages who have acute lymphoblastic leukemia (ALL).
The product is a freeze-dried formulation of liquid pegaspargase, which is already approved for the aforementioned indication.
The CHMP’s recommendation regarding lyophilized pegaspargase will be submitted to the European Commission (EC).
The EC typically adheres to the CHMP’s recommendations and delivers its final decision within 67 days of the CHMP’s recommendation.
The EC’s decision will be applicable to the entire European Economic Area—all member states of the European Union plus Iceland, Liechtenstein, and Norway.
The CHMP’s recommendation regarding lyophilized pegaspargase is based on analytical and nonclinical studies, which indicate that lyophilized pegaspargase is comparable to the liquid formulation.
Once reconstituted, lyophilized pegaspargase demonstrates similar pharmacokinetics and pharmacodynamics as liquid pegaspargase.
“Lyophilized ONCASPAR builds on more than a decade of data and research with liquid ONCASPAR, and, with no change in dosing regimen, it offers a 3-times longer shelf life,” said Howard B. Mayer, MD, of Shire, the company that developed lyophilized pegaspargase.
“Prolonging shelf life to 24 months for this critically important therapy facilitates management of product inventory by enabling greater flexibility and longer-term planning. Once approved, with the extended shelf life of lyophilized ONCASPAR, we also hope to improve access to the medicine for ALL patients in countries currently not offering liquid ONCASPAR.”
Lyophilized pegaspargase works in the same way as the liquid formulation. It rapidly depletes serum L-asparagine levels and interferes with protein synthesis, thereby depriving lymphoblasts of asparaginase and resulting in cell death.
