Leighton's story—completing treatment with RYLAZE
Dosing and Administration
When replacing a long-acting asparaginase product, the recommended dosage of RYLAZE is:
- 25 mg/m2 administered intramuscularly (IM) every 48 hours1
See the full prescribing information for the long-acting asparaginase product to determine the duration of administration of RYLAZE as replacement therapy.1
RYLAZE is administered by intramuscular injection.1
- Limit the volume of RYLAZE at a single injection site to 2 mL1
- If the volume to be administered is greater than 2 mL, divide the dose equally into multiple syringes, 1 for each injection site1
- Administer RYLAZE by intramuscular injection within 4 hours after drawing the dose into the syringe(s)1
- Rotate injection sites
- Do not inject RYLAZE into scar tissue or areas that are reddened, inflamed, or swollen
- If needed, store the syringe(s) at room temperature 59°F to 77°F or refrigerated at 36°F to 46°F for up to 4 hours. The syringe does not need to be protected from light during storage
- Ensure that medical support is available to appropriately manage anaphylactic reactions when administering RYLAZE1
Monitor patient’s bilirubin, transaminase, and glucose levels, and clinical examinations prior to treatment every 2-3 weeks and as indicated clinically.1
- If results are abnormal, monitor patients until recovery from the cycle of therapy1
- If an adverse reaction occurs, modify treatment according to the table below1
|Grade 3 to 4|
|Pancreatitis||Grade 2 to 4|
|Severe or life-threatening|
|Hemorrhage||Grade 3 to 4|
|Hepatotoxicity||Total bilirubin >3 times|
to ≤10 times the ULN
|Total bilirubin >10 times the ULN|
*Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
To calculate dose volume:
- Each single-dose vial of RYLAZE contains 10 mg/0.5 mL1
- Use the chart to determine the injection volume based on patient’s body surface area (BSA)
- Calculate the total volume of RYLAZE solution required for each dose:Volume(mL)=BSA(m2)xDose(25 mg/m2)÷Concentration(20 mg/mL)
- Calculate the total volume of RYLAZE solution required for each dose:
|BSA (m2)||Injection volume |
based on BSA, mL
|Number of vials |
per 25 mg/m2 dose
- Injection volume should be rounded based on institutional standard of care
- It is solely the responsibility of the treating healthcare professional and/or institution to determine the appropriate dosage for each patient and to appropriately account for any unused drug or wastage in accordance with any applicable law, regulation, or policy
- Healthcare professionals should calculate all doses before administration.

Sign up to stay informed
RYLAZE is indicated as a component of a multi-agent chemotherapeutic regimen given by intramuscular injection 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.
IMPORTANT SAFETY INFORMATION
RYLAZE is contraindicated in patients with a history of:
- Serious hypersensitivity reactions to Erwinia asparaginase, including anaphylaxis
- Serious pancreatitis during previous asparaginase therapy
- Serious thrombosis during previous asparaginase therapy
- Serious hemorrhagic events during previous asparaginase therapy
Warnings and Precautions
Hypersensitivity reactions after the use of RYLAZE occurred in 25% of patients in clinical trials, and it was severe in 2% of patients. The median time from the first dose of RYLAZE to the onset of the first hypersensitivity event was 27 days (range 1-171 days). The most commonly observed reaction was rash (17%), and no patient experienced a severe rash. The median time from the first dose to the first onset of rash was 33.5 days (range 1-127 days).
Hypersensitivity reactions observed with L-asparaginase class products include angioedema, urticaria, lip swelling, eye swelling, rash or erythema, blood pressure decreased, bronchospasm, dyspnea, and pruritus.
Because of the risk of serious allergic reactions (e.g., life-threatening anaphylaxis), administer RYLAZE in a setting with resuscitation equipment and other agents necessary to treat anaphylaxis (e.g., epinephrine, oxygen, intravenous steroids, antihistamines). Discontinue RYLAZE in patients with serious hypersensitivity reactions.
Pancreatitis was reported in 14% of patients in clinical trials of RYLAZE and was severe in 6%. Clinical pancreatitis occurred in 5% of patients, and it was severe in 4% of patients. Elevated amylase or lipase without clinical diagnosis of pancreatitis was observed in 9% of patients, and it was severe in 2% of patients treated with RYLAZE. Hemorrhagic or necrotizing pancreatitis have been reported with L-asparaginase class products.
Inform patients of the signs and symptoms of pancreatitis, which, if left untreated, could be fatal. Evaluate patients with symptoms compatible with pancreatitis to establish a diagnosis. Assess serum amylase and lipase levels in patients with any signs or symptoms of pancreatitis. Discontinue RYLAZE in patients with severe or hemorrhagic pancreatitis. In the case of mild pancreatitis, withhold RYLAZE until the signs and symptoms subside and amylase and/or lipase levels return to 1.5 times the ULN. After resolution of mild pancreatitis, treatment with RYLAZE may be resumed.
Serious thrombotic events, including sagittal sinus thrombosis and pulmonary embolism, have been reported following treatment with L-asparaginase class products. Discontinue RYLAZE for a thrombotic event, and administer appropriate antithrombotic therapy. Consider resumption of treatment with RYLAZE only if the patient had an uncomplicated thrombosis.
Bleeding was reported in 17% of patients treated with RYLAZE, and it was severe in 1%. Most commonly observed reactions were bruising (8%) (contusion, increased tendency to bruise and injection site bruising) and nose bleeding (6%), which was severe in 1% of patients. Other observed bleeding reactions included hematuria (2%), disseminated intravascular coagulopathy (1%), rectal bleeding (1%) and gingival bleeding (1%).
In patients treated with asparaginase class products, hemorrhage may be associated with increased prothrombin time (PT), increased partial thromboplastin time (PTT), and hypofibrinogenemia. Consider appropriate replacement therapy in patients with severe or symptomatic coagulopathy.
Elevated bilirubin and/or transaminases occurred in 62% of patients treated with RYLAZE in clinical trials, and 12% had Grade ≥3 elevations.
Inform patients of the signs and symptoms of hepatotoxicity. Evaluate bilirubin and transaminases prior to treatment every 2-3 weeks and as indicated clinically during treatment with RYLAZE. In the event of serious liver toxicity, discontinue treatment with RYLAZE and provide supportive care.
Serious adverse reactions occurred in 55% of patients who received RYLAZE. The most frequent serious adverse reactions (in ≥5% of patients) were febrile neutropenia, dehydration, pyrexia, stomatitis, diarrhea, drug hypersensitivity, infection, nausea, and viral infection.
The most common adverse reactions (incidence >20%) with RYLAZE are abnormal liver test (70%), nausea (46%), musculoskeletal pain (39%), fatigue (36%), infection (30%), headache (30%), pyrexia (27%), drug hypersensitivity (24%), febrile neutropenia (24%), decreased appetite (21%), stomatitis (21%), bleeding (21%), and hyperglycemia (21%).
