Primary Outcome Measures:
  • Reduction in serum MTX concentration

Secondary Outcome Measures:
  • serum blood-urea-nitrogen
  • serum creatinine
  • creatinine clearance
  • haematology (complete blood count and differential)
  • biochemistry (electrolytes, SGOT, SGPT, alkaline phosphatase, bilirubin, total protein)
  • urinalysis (dip-stick)
  • MTX-related toxicity
  • Adverse events
  • Mortality

Study Start Date: January 2000
Estimated Study Completion Date: June 2003

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

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
