Mechanism of action

Sourced from openFDA

Asparaginase erwinia chrysanthemi (recombinant)-rywn is an enzyme that catalyzes the conversion of the amino acid L-asparagine into aspartic acid and ammonia. The pharmacological effect of RYLAZE is based on the killing of leukemic cells due to depletion of plasma asparagine.

Indications

Sourced from openFDA
  • RYLAZE is indicated as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adult and pediatric patients 1 month or older who have developed hypersensitivity to E. coli -derived asparaginase.ICD-10: C85.90, C95.90

Contraindications

Sourced from openFDA
  • RYLAZE is contraindicated in patients with: • History of serious hypersensitivity reactions to Erwinia asparaginase , including anaphylaxis [see Warnings and Precautions ( 5.1 )] ; • History of serious pancreatitis during previous asparaginase therapy [see Warnings and Precautions ( 5.2 )] ; • History of serious thrombosis during previous asparaginase therapy [see Warnings and Precautions ( 5.3 )] ; • History of serious hemorrhagic events during previous asparaginase therapy [see Warnings and Precautions ( 5.4 )] ; • Severe hepatic impairment [ see Warnings and Precautions ( 5.5 ) ]. RYLAZE is contraindicated in patients with: • History of serious hypersensitivity reactions to RYLAZE, including anaphylaxis.contraindicated

Dosage & administration

Sourced from openFDA

There are two RYLAZE regimens that can be used to replace a long-acting asparaginase product. The recommended dosages of RYLAZE are: When administered every 48 hours • 25 mg/m 2 intramuscularly every 48 hours; When administered Monday/Wednesday/Friday • 25 mg/m 2 intramuscularly on Monday morning and Wednesday morning and 50 mg/m 2 intramuscularly on Friday afternoon. ( 2.1 ) 2.1 Recommended Dosage There are two RYLAZE regimens that can be used to replace a long-acting asparaginase product. The recommended dosages of RYLAZE are: When administered every 48 hours: • 25 mg/m 2 administered intramuscularly every 48 hours; When administered on a Monday/Wednesday/Friday schedule: • 25 mg/m 2 intramuscularly on Monday morning and Wednesday morning, and 50 mg/m 2 intramuscularly on Friday afternoon. Administer the Friday afternoon dose 53 to 58 hours after the Wednesday morning dose (e.g., 8:00 am on Monday and Wednesday, and 1:00 pm to 6:00 pm on Friday) [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14 )] . Table 1 shows the number of RYLAZE dosages recommended for the intended duration of treatment for replacement of one dose of calaspargase pegol products (3 weeks of asparaginase coverage) or one dose of pegaspargase products (2 weeks of asparaginase coverage). See the full prescribing information for the long-acting asparaginase product to determine the total duration of administration of RYLAZE as replacement therapy.

Warnings & precautions

Sourced from openFDA

• Hypersensitivity: Monitor for signs or symptoms. Discontinue RYLAZE for serious reaction. ( 5.1 ) • Pancreatitis: Monitor for symptoms. Discontinue if pancreatitis occurs. ( 5.2 ) • Thrombosis: Discontinue RYLAZE for severe or life-threatening thrombosis. Provide anticoagulation therapy as indicated. ( 5.3 ) • Hemorrhage: Discontinue RYLAZE for severe or life-threatening hemorrhage. ( 5.4 ) • Hepatotoxicity, including hepatic veno-occlusive disease: Discontinue RYLAZE for grade 4 increases of bilirubin. ( 5.5 ) 5.1 Hypersensitivity Reactions Hypersensitivity reactions after the use of RYLAZE occurred in 29% of patients in clinical trials, and it was severe in 6% of patients [see Adverse Reactions ( 6.1 )] . Anaphylaxis was observed in 2% of patients after intramuscular administration. Discontinuation of RYLAZE due to hypersensitivity reactions occurred in 5% of patients. Hypersensitivity reactions were higher in patients who received intravenous asparaginase erwinia chrysanthemi (recombinant)-rywn. The intravenous route of administration is not approved. In patients administered RYLAZE intramuscularly in clinical trials, the median number of doses of RYLAZE that patients received prior to the onset of the first hypersensitivity reaction was 12 doses (range: 1-64 doses). The most commonly observed reaction was rash (19%), and 1 patient (1%) experienced a severe rash.

Adverse reactions

Sourced from openFDA

The following clinically significant adverse reactions are described in greater detail in other sections of the labeling: • Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] • Pancreatic Toxicity [see Warnings and Precautions ( 5.2 )] • Thrombosis [see Warnings and Precautions ( 5.3 )] • Hemorrhage [see Warnings and Precautions ( 5.4 )] • Hepatotoxicity, including VOD [see Warnings and Precautions ( 5.5 )] Most common adverse reactions (incidence > 20%) are abnormal liver test, nausea, musculoskeletal pain, infection, fatigue, headache, febrile neutropenia, pyrexia, hemorrhage, stomatitis, abdominal pain, decreased appetite, drug hypersensitivity, hyperglycemia, diarrhea, pancreatitis, and hypokalemia.

The safety of RYLAZE described in the WARNINGS AND PRECAUTIONS reflect exposure in 167 patients administered RYLAZE intramuscularly at various dosages when used in combination with chemotherapy in study JZP458-201 [see Clinical Studies ( 14 )] . These patients received a median of 4 courses of RYLAZE (range: 1-15 courses); 65% of patients received at least four courses.

Use in specific populations

Sourced from openFDA

• Lactation: Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings from animal reproduction studies, RYLAZE can cause fetal harm when administered to a pregnant woman. There are no available data on RYLAZE use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproductive and developmental toxicity studies, intramuscular administration of asparaginase Erwinia chrysanthemi to pregnant rats and rabbits during organogenesis resulted in structural abnormalities and embryo-fetal mortality ( see Data ) at exposures below those in patients at the recommended human dose. 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 reproductive and developmental toxicity studies have not been conducted with RYLAZE. In embryofetal development studies, asparaginase Erwinia chrysanthemi was administered intramuscularly every other day during the period of organogenesis to pregnant rats (at 3, 6, or 12 mg/m 2 ) and rabbits (at 0.12, 0.30, or 0.48 mg/m 2 ).

Pharmacokinetics

Sourced from openFDA
Metabolism
The pharmacokinetic parameters of asparaginase erwinia chrysanthemi (recombinant)-rywn are presented based on serum asparaginase activity (SAA) after administration of RYLAZE in pediatric and young adult patients with ALL or LBL, unless otherwise specified. Asparaginase erwinia chrysanthemi (recombinant)-rywn maximum SAA (C max ) and area under the SAA-time curve (AUC) increase proportionally over a dosage range from 12.5 to 50 mg/m 2 (0.25 to 1 times the maximum approved recommended dose of 50 mg/m 2 ).
