Patient Information:
PATIENT COUNSELING INFORMATION
1. Serious Allergic Reactions
Inform patients of the possibility of serious allergic reactions, including anaphylaxis,
and to seek immediate medical care for any swellings or difficulty breathing.
2. Thrombosis
Inform patients to seek immediate medical attention for severe headache,
arm or leg swelling, acute shortness of breath, or chest pain.
3. Pancreatitis
Advise patients to seek immediate medical attention for severe abdominal pain.
4. Glucose Intolerance
Advise patients to immediately report excessive thirst or increase in the volume
or frequency of urination.
Pharmacology/ Pharmacokinetics:
CLINICAL PHARMACOLOGY
1. Mechanism of Action
The mechanism of action of Oncaspar® is thought to be based on selective killing
of leukemic cells due to depletion of plasma asparagine. Some leukemic cells
are unable to synthesize asparagine due to a lack of asparagine synthetase
and are dependent on an exogenous source of asparagine for survival.
Depletion of asparagine, which results from treatment with the enzyme L-asparaginase,
kills the leukemic cells. Normal cells, however, are less affected by the depletion
due to their ability to synthesize asparagine
:
2. Pharmacokinetics
Pharmacokinetic assessments were based on an enzymatic assay measuring
asparaginase activity. Serum pharmacokinetics were assessed in 34 newly
diagnosed pediatric patients with standard-risk ALL in Study 1 following
intramuscular administration of 2,500 International Units/m2 .
The elimination half-life of Oncaspar® was approximately 5.8 days during the
induction phase. Similar elimination half-lives were observed during
Delayed Intensification 1 and Delayed Intensification 2
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1. Pregnancy
Pregnancy Category C.
Animal reproduction studies have not been conducted with Oncaspar® .
It is also not known whether Oncaspar® can cause fetal harm when administered
to a pregnant woman or can affect reproduction capacity.
Oncaspar® should be given to a pregnant woman only if clearly needed.
2. Nursing Mothers
It is not known whether Oncaspar® is excreted in human milk. Because many drugs
are excreted in human milk and because of the potential for serious adverse
reactions in nursing infants from Oncaspar®, a decision should be made to
discontinue nursing or discontinue the drug, taking into account the importance
of the drug to the mother.
3. Geriatric Use
Clinical studies of Oncaspar® did not include sufficient numbers of subjects
aged 65 years and older to determine whether they respond differently than
younger subjects.
