Drug Description

RYLAZE®
(asparaginase erwinia chrysanthemi (recombinant) - rywn) Injection, for Intramuscular Use

DESCRIPTION

Asparaginase erwinia chrysanthemi (recombinant)-rywn contains an asparagine specific bacterial enzyme (L-asparaginase). L-asparaginase is a tetrameric enzyme that consists of four identical 35 kDa subunits with a combined molecular weight of 140 kDa. The amino acid sequence is identical to native asparaginase Erwinia chrystanthemi (also known as crisantaspase). The activity of asparaginase erwinia chrysanthemi (recombinant)-rywn is expressed in units, defined as the amount of enzyme that catalyzes the conversion of 1μmol of L-asparagine per reaction minute, per mg of protein.

Asparaginase erwinia chrysanthemi (recombinant)-rywn is produced by fermentation of a genetically engineered Pseudomonas fluorescens bacterium containing the DNA which encodes for asparaginase Erwinia chrysanthemi.

RYLAZE (asparaginase erwinia chrysanthemi (recombinant)-rywn) injection is supplied as a sterile, clear to opalescent, colorless to slightly yellow, preservative-free solution for intramuscular injection. Each 0.5 mL contains 10 mg asparaginase erwinia chrysanthemi (recombinant)-rywn and the inactive ingredients: polysorbate 80 (0.1 mg), sodium chloride (1.5 mg), sodium phosphate dibasic anhydrous (0.8 mg), sodium phosphate monobasic monohydrate (0.6 mg), and trehalose (32.1 mg). Sodium hydroxide may be added to adjust the pH. The pH is approximately 7.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of RYLAZE described in the WARNINGS AND PRECAUTIONS reflect exposure to RYLAZE at various dosages, including dosage other than the recommended, used in combination with chemotherapy in 102 patients in JZP458-201 [see Clinical Studies]. These patients received a median of 3 courses of RYLAZE (range: 1-14 courses); 38% of patients received at least four courses.

The safety of RYLAZE described below was evaluated in a cohort of 33 patients from JZP458-201 who received RYLAZE 25 mg/m² intramuscularly on Monday, Wednesday, and Friday for 6 doses as a replacement for a single dose of pegaspargase as a component of multi-agent chemotherapy [see Clinical Studies]. The patients had a median age of 11 years (range: 1 to 24 years); the majority of patients were male (51%) and white (73%). The patients received a median of 4 courses of RYLAZE (range: 1-14 cycles); 48% of patients received at least four courses.

A fatal adverse reaction (infection) occurred in 1 patient treated with the RYLAZE 25 mg/m² dosage. Serious adverse reactions occurred in 55% of patients who received the RYLAZE 25 mg/m² dosage.

The most frequent serious adverse reactions (in ≥ 5% of patients) were febrile neutropenia, dehydration, pyrexia, stomatitis, diarrhea, drug hypersensitivity, infection, nausea, and viral infection. Permanent discontinuation due to an adverse reaction occurred in 9% of patients who received the RYLAZE 25 mg/m² dosage. Adverse reactions resulting in permanent discontinuation included hypersensitivity (6%) and infection (3%).

All patients treated with the RYLAZE 25 mg/m² dosage as a component of multi-agent chemotherapy developed neutropenia, anemia, or thrombocytopenia. The most common nonhematological adverse reactions in patients were abnormal liver test, nausea, musculoskeletal pain, fatigue, infection, headache, pyrexia, drug hypersensitivity, febrile neutropenia, decreased appetite, stomatitis, bleeding, and hyperglycemia. Table 2 shows the common adverse reactions occurring in at least 15% of the patients.

PRECAUTIONS

Hypersensitivity Reactions

Hypersensitivity reactions after the use of RYLAZE occurred in 25% of patients in clinical trials, and it was severe in 2% of patients [see ADVERSE REACTIONS]. 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) [see DOSAGE AND ADMINISTRATION]. Discontinue RYLAZE in patients with serious hypersensitivity reactions.

Pancreatitis

Pancreatitis was reported in 14% of patients in clinical trials of RYLAZE and was severe in 6% [see ADVERSE REACTIONS]. 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 [see DOSAGE AND ADMINISTRATION]. After resolution of mild pancreatitis, treatment with RYLAZE may be resumed.

Thrombosis

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 [see DOSAGE AND ADMINISTRATION].

Hemorrhage

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%) [see ADVERSE REACTIONS].

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 [see DOSAGE AND ADMINISTRATION].

Hepatotoxicity

Elevated bilirubin and/or transaminases occurred in 62% of patients treated with RYLAZE in clinical trials, and 12% had Grade ≥ 3 elevations [see ADVERSE REACTIONS].

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 [see DOSAGE AND ADMINISTRATION].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity, mutagenicity, and impairment of fertility studies have not been conducted with asparaginase erwinia chrysanthemi (recombinant)-rywn.

In a fertility and early embryonic development study in rats, asparaginase Erwinia chrysanthemi had no effect on male or female fertility when administered intramuscularly at doses of up to 12 mg/m² (approximately 0.48 times the maximum recommended human dose) every other day for a total of 35 doses. In males, decreased sperm count was observed at all doses but did not impact fertility.

Use In Specific Populations

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/m²) and rabbits (at 0.12, 0.30, or 0.48 mg/m²). In rats given 12 mg/m² (approximately 0.48 times the maximum recommended human dose), maternal toxicity of decreased body weight gain was observed, as was a fetal finding of increased incidence of partially undescended thymic tissue. In rabbits, maternal toxicity consisting of decreased body weight was observed at 0.48 mg/m² (approximately 0.02 times the maximum recommended human dose). Increased post-implantation loss, a decrease in the number of live fetuses, and gross abnormalities (e.g., absent kidney, absent accessory lung lobe, additional subclavian artery, and delayed ossification) were observed at doses of ≥ 0.12 mg/m² (approximately 0.005 times the maximum recommended human dose).

Lactation

Risk Summary

There are no data on the presence of asparaginase erwinia chrysanthemi (recombinant)-rywn 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 RYLAZE and for 1 week after the last dose.

Females And Males Of Reproductive Potential

RYLAZE can cause fetal harm when administered to a pregnant woman [see Use In Specific Populations].

Pregnancy Testing

Pregnancy testing is recommended in females of reproductive potential prior to initiating RYLAZE.

Contraception

Advise females of reproductive potential to use effective non-hormonal contraceptive methods during treatment with RYLAZE and for 3 months after the last dose.

Pediatric Use

The safety and effectiveness of RYLAZE in the treatment of ALL and LBL have been established in pediatric patients 1 month to < 17 years who have developed hypersensitivity to a long-acting E. coliderived asparaginase. Use of RYLAZE in these age groups is supported by evidence from an adequate and well-controlled study in adults and pediatric patients. The trial included 84 pediatric patients, including 2 infants (1 month to < 2 years), 62 children (2 years to < 12 years old), and 20 adolescents (12 years to < 17 years old). There were no clinically meaningful differences in safety or nadir serum asparaginase activity across age groups. The safety and effectiveness of RYLAZE have not been established in pediatric patients younger than 1 month of age.

Geriatric Use

Clinical studies of RYLAZE did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger patients.

Overdosage & Contraindications

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

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. 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.

Pharmacodynamics

Asparaginase erwinia chrysanthemi (recombinant)-rywn exposure-response relationships and the time course of pharmacodynamic response are unknown.

Pharmacokinetics

The pharmacokinetic parameters of asparaginase erwinia chrysanthemi (recombinant)-rywn are presented based on serum asparaginase activity (SAA) following administration of the approved recommended dosage in pediatric and young adult patients (1 to 24 years), unless otherwise specified. The exposures for asparaginase erwinia chrysanthemi (recombinant)-rywn are summarized in Table 3. Asparaginase erwinia chrysanthemi (recombinant)-rywn maximum SAA (Cmax) and area under the SAA-time curve (AUC) increase proportionally over a dosage range from 12.5 to 50 mg/m² (0.5 to 2 times the approved recommended dose of 25 mg/m²).

Table 3: RYLAZE Pharmacokinetic Parameters Based on SAA

Parameter Dose in Course Geometric Mean (%CV)
Cmax (U/mL) 1 1.80 (40%)
7 2.24 (42%)
C48ha (U/mL) 1 0.33 (88%)
7 0.40 (93%)
AUC0-48h (h•U/mL) 1 37.9 (39%)
7 48.5 (41%)
a SAA 48 hours after the most recent dose

The median tmax of asparaginase erwinia chrysanthemi (recombinant)-rywn is 10 hours. The mean absolute bioavailability for IM administration is 37% in healthy subjects.

Distribution

The geometric mean (%CV) apparent volume of distribution of asparaginase erwinia chrysanthemi (recombinant)-rywn is 1.48 L/m² (49%).

Elimination

The geometric mean (%CV) apparent clearance of asparaginase erwinia chrysanthemi (recombinant)-rywn is 0.31 L/hour/m² (36%) and the apparent half-life is 18.2 hours (16%).

Metabolism

Asparaginase erwinia chrysanthemi (recombinant)-rywn is expected to be metabolized into small peptides by catabolic pathways.

Specific Populations

There were no clinically significant differences in the pharmacokinetics of asparaginase erwinia chrysanthemi (recombinant)-rywn based on age (1 to 52 years), weight (9 to 131 kg), or sex after the dose was adjusted by body surface area (BSA). The effect of renal and hepatic impairment on the pharmacokinetics of asparaginase erwinia chrysanthemi (recombinant)-rywn has not been studied.

Body Surface Area

The apparent volume of distribution and apparent clearance of asparaginase erwinia chrysanthemi (recombinant)-rywn increase with increasing BSA (0.44 to 2.53 m²).

Race And Ethnicity

Black (n=10) and Asian (n=5) patients had 29% lower clearance which may increase SAA exposure compared to White (n=61) patients. There were no clinically significant differences in clearance between Hispanic (n=28) and Non-Hispanic (n=53) patients.

Clinical Studies

The efficacy of RYLAZE for the treatment of patients with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) who have developed hypersensitivity to E. coli-derived asparaginase as a component of a multi-agent chemotherapeutic regimen was evaluated in Study JZP458-201 (NCT04145531), an open-label, multi-cohort, multicenter trial. A treatment course consisted of RYLAZE at various dosages administered intramuscularly every Monday, Wednesday, and Friday for a total of 6 doses to replace each dose of pegaspargase.

For the 102 patients treated, the median age was 10 years (range, 1 -24 years); 57% were male and 43% were female; 73% were white, 12% were Black/African American, 5% were Asian, and 10% were of other or unknown race. Ninety-seven (94%) patients had experienced a hypersensitivity reaction to pegaspargase, and 6 patients (7%) had reported silent inactivation.

The determination of efficacy was based on a demonstration of the achievement and maintenance of nadir serum asparaginase activity (NSAA) above the level of 0.1 U/mL. The results of modeling and simulations showed that for a dosage of 25 mg/m² administered intramuscularly every 48 hours, the proportion of patients maintaining NSAA ≥ 0.1 U/mL at 48 hours after a dose of RYLAZE was 93.6% (95% CI: 92.6%, 94.6%) [see CLINICAL PHARMACOLOGY].
