30 June 2021 - Today, the U.S. FDA approved Rylaze (asparaginase erwinia chrysanthemi (recombinant)-rywn) as a component of a chemotherapy regimen to treat acute lymphoblastic leukaemia and lymphoblastic lymphoma in adult and paediatric patients who are allergic to the E. coli derived asparaginase products used most commonly for treatment.
