Leucovorin and extracorporeal removal of methotrexate (MTX) have limited efficacy in delayed MTX elimination after high-dose methotrexate (HD-MTX) therapy. Glucarpidase (carboxypeptidase G2) cleaves MTX into nontoxic metabolites, but experience with this enzyme is limited in adult patients. We evaluated the effects of glucarpidase intervention in adult and elderly patients with delayed MTX elimination.
