Guidelines

NATIONAL CANCER INSTITUTE COMMON TERMINOLOGY CRITERIA FOR ADVERSE EVENTS

The National Cancer Institute Common Terminology Criteria for Adverse Events describes the severity of adverse events (i.e., organ toxicity) for individuals receiving chemotherapy. Adverse events are evaluated on a Grade Scale of 1 to 5 with unique clinical descriptions of severity for each adverse event. The general guideline is:
  • Grade 1: Mild: asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated
  • Grade 2: Moderate: minimal, local, or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL)
  • Grade 3: Severe or medically significant but not immediately life-threatening: hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL
  • Grade 4: Life-threatening​ consequences; urgent intervention indicated
  • Grade 5: Death related to adverse event
For additional information about organ-specific clinical descriptions refer to https://ctep.cancer.gov/protocoldevelopment/electronic_applications/ctc.htm.

BENEFIT APPLICATION

Subject to the terms and conditions of the applicable benefit contract, asparaginase erwinia chrysanthemi [recombinant]-rywn (Rylaze) is covered under the medical benefits of the Company’s products when the medical necessity criteria listed in this medical policy are met.

US FOOD AND DRUG ADMINISTRATION (FDA) STATUS

Asparaginase erwinia chrysanthemi [recombinant]-rywn (Rylaze) was approved by the FDA on​ June 30, 2021, for the treatment of individuals with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adult and pediatric individuals 1 month or older who have developed hypersensitivity to Escherichia coli (E. coli)–derived asparaginase.

PEDIATRIC ​
The safety and effectiveness of asparaginase erwinia chrysanthemi [recombinant]-rywn (Rylaze) have been established in pediatric individuals ages 1 month and older as a component of a multiagent chemotherapeutic regimen for the treatment of individuals with ALL and LBL​ who have developed hypersensitivity to E. coli–​derived asparaginase.​

Description

According to the American Cancer Society, there are approximately 6590 new cases of acute lymphoblastic leukemia (ALL) (occurring in children and adults) in the United States. Children younger than 5 years of age have the highest level of risk for developing ALL. ALL, also known as acute lymphocytic leukemia, is a cancer that starts in the white blood cell precursors in the bone marrow and progresses rapidly to spread to other parts of the body.

Treatment for ALL is typically divided into several phases: induction, consolidation, and maintenance. Induction therapy is the initial phase of treatment with the objective of achieving complete remission. Consolidation, or the intensification phase, is a shorter period of chemotherapy to further reduce the amount of leukemic cells and to prevent the development of drug resistance. The individual's level of risk will determine the intensity of the chemotherapy regimen. The maintenance phase helps to prolong the duration of remission.

Asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) is an enzyme that catalyzes the conversion of the amino acid L-asparagine into aspartic acid and ammonia. Cancer cells need a source of L-asparagine to survive and function. The cancer cells cannot produce L-asparagine on their own, so they rely on an external source. Asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) exhausts any supply of L-asparagine in the cancer cells, which results in an anticancer effect through cell death. Asparaginase is commonly used for the treatment of ALL. Clinical studies have demonstrated that asparaginase can be used to achieve complete remission for individuals during their first relapse.

ASPARAGINASE​ ERWINIA CHRISANTHEMI (RECOMBINANT)-RYWN (RYLAZE) 

On June 30, 2021, asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze)​ was approved by the US Food and Drug Administration (FDA) for use as a component of a multiagent chemotherapeutic regimen for the treatment of ALL or LBL in pediatric and adult individuals aged 1 month and older who have developed hypersensitivity to Escherichia coli (E. coli)–derived asparaginase. 

Asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) 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 chrysanthemi (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 1 μmol 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 that encodes for asparaginase erwinia chrysanthemi. 

The safety of asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) was evaluated in a cohort of 33 individuals from ​the study JZP458-201 (NCT04145531) who received asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) 25 mg/m2 intramuscularly on Monday, Wednesday, and Friday for six doses as a replacement for a single dose of pegaspargase (Oncaspar) as a component of multiagent chemotherapy. The individuals had a median age of 11 years (range, 1 to 24 years); the majority of individuals were male (51 percent) and white (73 percent). The individuals received a median of four courses of Rylaze (range, 1 to 14 cycles); 48 percent of individuals received at least four courses.  

The safety and effectiveness of asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze) in the treatment of ALL and LBL have been established in pediatric individuals 1 month to less than 17 years who have developed hypersensitivity to a long-acting E. coli–derived asparaginase. The trial included 84 pediatric individuals, including two infants (1 month to <2 years), 62 children (2 years to <12 years old), and 20 adolescents (12 years to <17 years old). The safety and effectiveness of asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze)​ have not been established in pediatric individuals younger than 1 month of age. The most frequent serious adverse reactions (in 5 percent or greater of individuals) were febrile neutropenia, dehydration, pyrexia, stomatitis, diarrhea, drug hypersensitivity, infection, nausea, and viral infection. Permanent discontinuation due to an adverse reaction occurred in 9 percent of individuals who received the asparaginase erwinia chrysanthemi (recombinant)-rywn (Rylaze)​ 25 mg/m2 dosage. Adverse reactions resulting in permanent discontinuation included hypersensitivity (6 percent) and infection (3 percent).

OFF-LABEL INDICATIONS 

There may be additional indications contained in the Policy section of this document due to evaluation of criteria highlighted in the Company’s off-label policy, and/or review of clinical guidelines issued by leading professional organizations and government entities.
