Erwinase®

ERWINASE®: 10 000 Units,
Lyophilisate for solution for injection.
Crisantaspase (Asparaginase from Erwinia chrysanthemi; Erwinia L-asparaginase)

ERWINASE® is used in combination with other anti-neoplastic agents to treat Acute Lymphoblastic Leukemia (ALL). It may also be used in other neoplastic conditions where depletion of asparaginase might be expected to have a useful effect.*

Asparagine is an amino acid that is essential for cell growth; it is produced by most cells. Neoplastic cells associated with ALL are lacking asparaginase synthetase activity and rely on asparagine circulating in the blood for growth. L-Asparaginase is an enzyme that lowers circulating asparagine levels in the blood thereby depriving the mutated blood cells of asparagine and inhibiting their growth producing anti-neoplastic effect.

There are different types of L-asparaginase available, each derived from a different bacterium. Patients receiving treatment with L-asparaginase derived from Escherichia coli, who develop hypersensitivity to that form of the enzyme, may be able to continue treatment with ERWINASE® as the enzymes are immunologically distinct. Antibodies targeting E. coli derived L-Asparaginase have been shown not to cross-react with ERWINASE®.

In the US, Erwinase® is an Investigational New Drug (IND) which can only be made available on a named patient basis, the latest information on current Erwinase trials can be found at www.clinicaltrials.gov.
