The PEG-enhanced version of L-asparaginase, pegaspargase (Oncaspar, Enzon Pharmaceuticals), has been approved by the FDA as a component of a multi-agent chemotherapeutic regimen for the first-line treatment of patients with acute lymphoblastic leukemia (ALL). The biologic was approved in 1994 only for patients with ALL who were allergic to L-asparaginase.
