The most common grade 3 and 4 adverse reactions (>5%) included: hypoalbuminemia, elevated transaminase, febrile neutropenia, hypertriglyceridemia, hyperglycemia, bilirubin increased, pancreatitis, abnormal clotting studies, embolic and thrombotic events, hypersensitivity, sepsis, and infections. First-Line Treatment of Acute Lymphoblastic Leukemia (ALL) Study CCG-1962 was a randomized (1:1), active controlled study that enrolled 118 patients, with a median age of 4.7 years (1.1-9.9 years), of whom 54% were males and 65% White, 14% Hispanic, 8% Black, 8% Asian, and 6% other race. Of the 59 patients in Study 1 who were randomized to ONCASPAR, 48 patients (81%) received all 3 planned doses of ONCASPAR, 6 (10%) received 2 doses, 4 (7%) received 1 dose, and 1 patient (2%) did not receive the assigned treatment. In Study CCG-1962, detailed safety information was collected for pre-specified adverse reactions identified as asparaginase induced adverse reactions and for grade 3 and 4 nonhematologic adverse reactions according to the Children's Cancer Group (CCG) Toxicity and Complication Criteria. The per-patient incidence, by treatment arm, for these selected adverse reactions occurring at a severity of grade 3 or 4 are presented in Table 2: Table 2. Incidence of Selected Grades 3 and 4 Adverse Reactions in Study CCG-1962 ONCASPAR (n=58) Native E. coli L-Asparaginase (n=59) Infection 3 (5%) 3 (5%) Abnormal Liver Tests 3 (5%) 5 (8%) Elevated Transaminases Aspartate aminotransferase, alanine aminotransferase. 2 (3%) 4 (7%) Hyperbilirubinemia 1 (2%) 1 (2%) Hyperglycemia 3 (5%) 2 (3%) Central Nervous System Thrombosis 2 (3%) 2 (3%) Coagulopathy Prolonged prothrombin time or partial thromboplastin time; or hypofibrinogenemia. 1 (2%) 3 (5%) Pancreatitis 1 (2%) 1 (2%) Allergic Reactions to Asparaginase 1 (2%) 0 The safety of ONCASPAR was investigated in Study DFCI 11-001, an open label, randomized, active-controlled multicenter clinical trial that included 119 children and adolescents with newly diagnosed ALL or lymphoblastic lymphoma treated with ONCASPAR in combination with the Dana Farber Cancer Institute (DFCI) ALL Consortium backbone therapy. The median age on enrollment was 4 years (range, 1-18 years). The majority of patients were male (60%) and white (75%). Most patients were considered standard risk ALL (59%) and had B-cell lineage ALL (87%). The median number of doses of ONCASPAR during the study was 16 doses (one dose during induction therapy then administered every two weeks during post induction therapy). The median duration of exposure to ONCASPAR was 8 months. Table 3 summarizes the incidence of selected Grades ≥3 adverse reactions that occurred in 2 or more patients receiving ONCASPAR. Because not all grade 1 and 2 adverse reactions were collected prospectively, only grade 3 and 4 adverse reactions are presented in Table 3. Table 3. Incidence of Selected Grades ≥3 Adverse Reactions in Patients Receiving ONCASPAR With Multi-Agent Chemotherapy in Study DFCI 11-001 Adverse Reaction Grouped terms: Elevated transaminase : Alanine aminotransferase increased, Aspartate aminotransferase increased; Pancreatitis : Amylase increased, Lipase increased, Pancreatic necrosis, Pancreatitis, Pancreatitis relapsing; Bilirubin increased : Bilirubin conjugated increased, Blood bilirubin increased; Abnormal clotting studies : Activated partial thromboplastin time prolonged, Blood fibrinogen decreased; Febrile neutropenia : Febrile neutropenia; Embolic and thrombotic events : Embolism, Pulmonary embolism, Thrombosis in device, Venous thrombosis, Venous thrombosis limb; Hypersensitivity : Hypersensitivity, Anaphylactic reaction, Drug hypersensitivity; Pneumonia: Lung infection, Pneumonia, Pneumonitis; Sepsis: Bacterial sepsis, Sepsis; Diarrhea : Colitis, Diarrhea, Enterocolitis, Neutropenic colitis; Hemorrhages SMQ (excludes laboratory terms): Disseminated intravascular coagulation, Epistaxis, Hematoma, Hemorrhage intracranial, Melena, Esophageal ulcer hemorrhage, Small intestinal hemorrhage, Upper gastrointestinal hemorrhage; Fungal infection: Fungal infection, Hepatic infection fungal, Respiratory tract infection fungal, Splenic infection fungal, Systemic candida.

Use in specific populations

Lactation : Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk summary Based on published literature studies with L-asparaginase in pregnant animals, ONCASPAR can cause fetal harm when administered to a pregnant woman. There are no available data on ONCASPAR use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Published literature studies in pregnant animals suggest asparagine depletion may cause harm to the animal offspring (see Data ) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data Animal reproduction studies have not been conducted with ONCASPAR to evaluate its effect on reproduction and fetal development. Published literature studies in which pregnant rabbits were administered L-asparaginase or pregnant rats were deprived of dietary asparagine suggested harm to the animal offspring. 8.2 Lactation Risk summary There are no data on the presence of pegaspargase in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for adverse reactions in the breastfed child, advise women not to breastfeed during treatment with ONCASPAR and for 1 month after the last dose. 8.3 Females and Males of Reproductive Potential ONCASPAR can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Pregnancy testing is recommended in females of reproductive potential prior to initiating ONCASPAR. Contraception Advise females of reproductive potential to use effective non-hormonal contraceptive methods during treatment with ONCASPAR and for 3 months after the last dose. 8.4 Pediatric Use The safety and effectiveness of ONCASPAR in the treatment of ALL have been established in pediatric patients. Use of ONCASPAR in these age groups is supported by evidence of efficacy as first-line treatment from one adequate and well-controlled trial, and evidence of efficacy for treatment of patients with hypersensitivity to asparaginase from four adequate and well-controlled trials [see Clinical Studies (14.1) ] , and safety data from 7 total trials. The pediatric patients treated with ONCASPAR 2,500 International Units/m 2 on these trials included 26 infants (1 month to <2 years old), 165 children (2 years to <12 years old), and 39 adolescents (12 to 17 years old). 8.5 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.

Overdosage

Three patients received 10,000 International Units/m 2 of ONCASPAR as an intravenous infusion. One patient experienced a slight increase in liver enzymes. A second patient developed a rash 10 minutes after the start of the infusion, which was controlled with the administration of an antihistamine and by slowing down the infusion rate. A third patient did not experience any adverse reactions. There is no specific antidote for ONCASPAR overdosage. In case of overdose, monitor patients closely for signs and symptoms of adverse reactions, and appropriately manage with symptomatic and supportive treatment.

Description

Pegaspargase is a conjugate of monomethoxypolyethylene glycol (mPEG) and L-asparaginase (L-asparagine amidohydrolase), an asparagine specific enzyme. L-asparaginase is a tetrameric enzyme that is produced endogenously by E. coli and consists of identical 34.5 kDa subunits. Approximately 69 to 82 molecules of mPEG are linked to L-asparaginase; the molecular weight of each mPEG molecule is about 5 kDa. ONCASPAR activity is expressed in International Units. ONCASPAR (pegaspargase) injection is supplied as a clear, colorless, preservative-free, isotonic sterile solution in phosphate-buffered saline, pH 7.3, for intramuscular use or for dilution prior to intravenous infusion. Each vial of ONCASPAR contains 3,750 International Units of pegaspargase in 5 mL of solution. Each milliliter contains 750 International Units of pegaspargase, dibasic sodium phosphate, USP (5.58 mg), monobasic sodium phosphate, USP (1.20 mg), and Sodium Chloride, USP (8.50 mg) in Water for Injection, USP.

Mechanism of action

12.1 Mechanism of Action L-asparaginase is an enzyme that catalyzes the conversion of the amino acid L-asparagine into aspartic acid and ammonia. The pharmacological effect of ONCASPAR is thought to be based on the killing of leukemic cells due to depletion of plasma asparagine. Leukemic cells with low expression of asparagine synthetase have a reduced ability to synthesize asparagine, and therefore depend on an exogenous source of asparagine for survival.

How supplied
