Elspar (Asparaginase) - Summary

 
 



WARNINGS

It is recommended that asparaginase be administered to patients only in a hospital setting under the supervision of a physician who is qualified by training and experience to administer cancer chemotherapeutic agents, because of the possibility of severe reactions, including anaphylaxis and sudden death. The physician must be prepared to treat anaphylaxis at each administration of the drug. In the treatment of each patient the physician must weigh carefully the possibility of achieving therapeutic benefit versus the risk of toxicity.

Special handling procedures should be followed (see DOSAGE AND ADMINISTRATION, Special Handling).

 

ELSPAR SUMMARY

ELSPAR * (Asparaginase) contains the enzyme L-asparagine amidohydrolase, type EC-2, derived from Escherichia coli. 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.

Published Studies Related to Elspar (Asparaginase)

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.

Comparison of native E. coli and PEG asparaginase pharmacokinetics and pharmacodynamics in pediatric acute lymphoblastic leukemia. [2009.12]

Clinical Trials Related to Elspar (Asparaginase)

Erwinase Study in Patients With Acute Lymphoblastic Leukemia [Recruiting]
The goal of this clinical research study is to allow doctors to use Erwinia L-Asparaginase (Erwinase®) as a replacement for patients who are allergic to E. coli L-asparaginase or Pegylated E. coli L-asparaginase as part of the treatment for acute lymphoblastic leukemia (ALL).
