Overview

Asparaginase erwinia chrysanthemi (recombinant)-rywn is an asparagine specific enzyme that is FDA approved for the treatment of acute lymphoblastic leukemia and lymphoblastic lymphoma in patients who are allergic to E. coli-derived asparaginase products, as a component of a chemotherapy regimen. Common adverse reactions include musculoskeletal pain, febrile neutropenia, hypokalemia, abnormal liver test, abdominal pain, hypersensitivity, pyrexia, fatigue, nausea, infection, decreased appetite, stomatitis, hemorrhage, diarrhea, drug hypersensitivity, pancreatitis, and hyperglycemia.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Treatment Options of Rylaze to replace a long-acting asparaginase product

  • Option 1 is 25 mg/m2 administered intramuscularly every 48 hours.
  • Option 2 is 25 mg/m2 intramuscularly in the mornings of Monday and Wednesday, and 50 mg/m2 intramuscularly in the afternoon on Friday. Friday dosage should be administered 53 to 58 hours after the Wednesday dose.

Table 1 summarizes Recommended Duration of Rylaze Dosing to Replace One Long-Acting Asparaginase Dose.

Insert Table 1

Recommended Pre-medication

  • 30-60 minutes prior to Rylaze treatment, consider administering an H-1 receptor blocker, acetaminophen, and an H-2 receptor blocker to reduce severity and risk of hypersensitivity reactions.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): Rylaze can be harmful to the fetus, based on animal reproduction studies, when given to pregnant women. No studies have been conducted to look at if Rylaze causes major birth defects, miscarriage or adverse maternal or fetal outcomes in humans. Embryo-fetal mortality and structural abnormalities were observed in pregnant rabbits and rats given asparaginase Erwinia chrysanthemi. Maternal toxicity of decreased body weight gain and increased incidence of partially undescended thymic tissue of rat fetus was observed when pregnant rats were given 12 mg/m2 of asparaginase Erwinia chrysanthemi. Maternal toxicity of decreased body weight was seen in rabbits that received 0.48 mg/m2 of asparaginase Erwinia chrysanthemi.
Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Asparaginase erwinia chrysanthemi (recombinant)-rywn in women who are pregnant.

Administration

Preparation and Administration Instructions

  • If anaphylactic reactions occur due to Rylaze treatment, seek medical support immediately.
  • Discard vial of Rylaze if there is cloudiness, particulate matter, or discoloration.
  • Use individual patient’s BSA to determine the number of Rylaze vials as well as the dose and total volume of Rylaze solution required for proper treatment.
  • Prepare injection with the correct amount of Rylaze solution determined.
  • Maximum amount of volume in syringe should be 2 mL.
  • If greater than 2 mL is required, then equally distribute volume needed into multiple syringes for one injection spot.
