RYLAZE
RYLAZE is an asparagine-specific enzyme indicated for use as a component of a multi-agent chemotherapeutic regimen. It is approved for the treatment of adult and pediatric patients aged one month and older with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). This therapy is specifically used in patients who have developed hypersensitivity to E. coli-derived asparaginase.
How RYLAZE Works
This drug is a recombinant enzyme that catalyzes the conversion of the amino acid L-asparagine into aspartic acid and ammonia. The therapeutic effect is achieved through the depletion of plasma asparagine, which leukemic cells require for survival. Because these leukemic cells have low expression of asparagine synthetase, they possess a reduced ability to synthesize their own asparagine and must rely on exogenous sources. Depleting the available supply of this amino acid leads to the death of the leukemic cells.
