Pharmacology
- Indication
For treatment of acute lymphoblastic leukemia
- Associated Conditions
- Pharmacodynamics
In a significant number of patients with acute leukemia, the malignant cells are dependent on an exogenous source of asparagine for survival. Normal cells, however, are able to synthesize asparagine and thus are affected less by the rapid depletion produced by treatment with the enzyme asparaginase. Oncaspar exploits a metabolic defect in asparagine synthesis of some malignant cells.
- Mechanism of action
Pegaspargase, more effective than asparaginase, converts asparagine to aspartic acid and ammonia. It facilitates production of oxaloacetate which is needed for general cellular metabolism. Some malignant cells lose the ability to produce asparagine and so the loss of exogenous sources of asparagine leads to cell death.
Target Actions Organism AL-asparagine other/unknownHumans - Absorption
Onset of Asparagine depletion by IM is within 4 days Time to peak: IM: 3 to 4 days
- Volume of distribution
IV: Adults (asparaginase naive): 2.4 L/m2 Distributes into CSF (reportedly reducing CSF asparagine concentrations to a similar extent as asparaginase

- Half life
IM: ~6 days; half-life decreased to ~3 days (range: 1.4 to 5 days) in patients with previous hypersensitivity to native L-asparaginase; IV: Adults (asparaginase naive): 7 days
- Clearance
- Not Available
- Toxicity
Adverse effects that occur more than 10% of the time include hepatotoxicity as it is known to increase serum transaminases (ALT, AST). Also known to induce hypersensitivity reactions including anaphylaxis, erythema and bronchospasm.
