ELSPAR * (Asparaginase) contains the enzyme L-asparagine amidohydrolase, type EC-2, derived from
It is a white crystalline powder that is freely soluble in water and practically insoluble in methanol, acetone and chloroform. Its activity is expressed in terms of International Units (I.U.) according to the recommendation of the International Union of Biochemistry. The specific activity of ELSPAR is at least 225 I.U. per milligram of protein and each vial contains 10,000 I.U. of asparaginase and 80 mg of mannitol, an inactive ingredient, as a sterile, white lyophilized plug or powder for intravenous or intramuscular injection after reconstitution.
ELSPAR is indicated in the therapy of patients with acute lymphocytic leukemia. This agent is useful primarily in combination with other chemotherapeutic agents in the induction of remissions of the disease in pediatric patients. ELSPAR should not be used as the sole induction agent unless combination therapy is deemed inappropriate. ELSPAR is not recommended for maintenance therapy.

l-asparaginase loaded red blood cells in refractory or relapsing acute lymphoblastic leukaemia in children and adults: results of the GRASPALL 2005-01 randomized trial. [2011.04]
l-asparaginase encapsulated within erythrocytes (GRASPA((R)) ) should allow serum asparagine depletion over a longer period than the native form of the enzyme, using lower doses and allowing better tolerance. The GRASPALL 2005-01 study, a multicentre randomized controlled trial, investigated three doses of GRASPA((R)) for the duration of asparagine depletion in a phase I/II study in adults and children with acute lymphoblastic leukaemia (ALL) in first relapse.
Asparaginase-related venous thrombosis in UKALL 2003- re-exposure to asparaginase is feasible and safe. [2010.05]
We report the incidence and outcome of venous thrombosis (VT) in the UK acute lymphoblastic leukaemia (ALL) 2003 trial. VT occurred in 59/1824 (3.2%) patients recruited over 5 years with 90% occurring during a period of Asparagine depletion... This report confirms a significant risk of thrombosis with such therapy, but demonstrates that re-exposure to Asparaginase is feasible and safe.
