Unfractionated heparin (UH) is a heterogenous preparation of anionic, sulfated glycosaminoglycan polymers with weights ranging from 3000 to 30,000 Da. It is a naturally occurring anticoagulant released from mast cells. It binds reversibly to antithrombin III (ATIII) and greatly accelerates the rate at which ATIII inactivates coagulation enzymes thrombin (factor IIa) and factor Xa. UH is different from low molecular weight heparin (LMWH) in the following ways: the average molecular weight of LMWH is about 4.5 kDa whereas it is 15 kDa for UH; UH requires continuous infusions; activated partial prothrombin time (aPTT) monitoring is required when using UH; and UH has a higher risk of bleeding and higher risk of osteoporosis in long term use.

Asparaginase is an important agent used to treat acute lymphoblastic leukemia (ALL) . Asparagine is incorporated into most proteins, and the synthesis of proteins is stopped when asparagine is absent, which inhibits RNA and DNA synthesis, resulting in a halt in cellular proliferation. This forms the basis of asparaginase treatment in ALL , , . Calaspargase pegol, also known as _asparlas_, is an asparagine specific enzyme which is indicated as a part of a multi-agent chemotherapy regimen for the treatment of ALL . The asparagine specific enzyme is derived from Escherichia coli, as a conjugate of L-asparaginase (L-asparagine amidohydrolase) and monomethoxypolyethylene glycol (mPEG) with a succinimidyl carbonate (SC) linker to create a stable molecule which increases the half-life and decreases the dosing frequency [FDA label], . Calaspargase pegol, by _Shire_ pharmaceuticals, was approved by the FDA on December 20, 2018 for acute lymphoblastic anemia (ALL) .
