glucarpidase ...Study Participants
NoneTo evaluate the safety and efficacy of glucarpidase in patients with impaired methotrexate (MTX) clearance owing to MTX-induced renal failure following high-dose MTX therapy, or with intrathecal MTX overdose.
Inclusion Criteria: Written informed consent by patient or legally valid representative Patients receiving high-dose MTX (>1 g/m2 body surface area (BSA) given as an infusion over 24 hours) for the treatment of ALL, NHL or a solid tumour (e.g. osteosarcoma) Age ≥ 18 years Serum MTX >5 µmol/L 42 hours or later after the start of MTX infusion, or serum MTX >1 μmol/L 42 hours or later after the start of MTX infusion together with renal insufficiency, or serum MTX >0.4 µmol/L 48 hours or later after the start of MTX infusion together with renal insufficiency. Renal insufficiency was defined as serum creatinine >1.5 × the upper limit of normal (ULN) and/or oliguria (urine output < 500 mL/24 hours despite adequate hydration, diuretics and alkalinisation). Exclusion Criteria: Pregnant or lactating females Unwillingness of patient or relative/legal representative to give informed consent
