Pegaspargase, sold under the brand name Oncaspar, is a medication used in the treatment of acute lymphoblastic leukemia (ALL).[2] Often it is used together with anthracycline, vincristine, and corticosteroids (for example prednisone and dexamethasone).[3] Pegaspargase can be administered either via an intravenous infusion or a intramuscular injection.[3]
Known side effects include allergic reactions, coagulopathy, high blood sugar, affected liver function, pancreas inflammation, and blood clots in the brain.[3] There is no data regarding the usage of pegaspargase during pregnancy.[4] Therefor caution should be observed and pegaspargase should only be used during pregnancy when the benefits outweigh the possible risks.
Pegaspargase is a modified version of the enzyme asparaginase which has undergone PEGylation.[5][3] It works by breaking down the amino acid asparagine that are circulating in the bloodstream.[3] The circulating asparagine is essential for the cancer cells to enable growth since they can't produce their own, in contrast to normal cells.[6] The normal cells are therefor less affected by pegaspargase.
Pegaspargase was approved for medical use in the United States in 1994.[3] It is on the World Health Organization's List of Essential Medicines.[7] It is made by Sigma-Tau.[3]
