Study of Glucarpidase (CPG2) for the Management of Patients With Delayed Methotrexate Clearance

September 10, 2014 updated by: BTG International Inc.

Study of Recombinant Carboxypeptidase G2 (CPG2) for the Management of Patients With Delayed Methotrexate (MTX) Clearance or Intrathecal MTX Overdosage

To 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.

Description

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
