Systemic Anti-Cancer Therapy Regimen Library
GMALL T-LBL 1/2004 [55 years and under] - Consolidation I (LEU ALL precursor T-cell - GMALL T-LBL 1/2004 [55 years and under])
Treatment Overview
Commencing week 11.
High dose metHOTREXATe
- metHOTREXATe levels MUST be measured once every 24 hours.
- Intravenous alkalinized fluids MUST be commenced at least 6 hours before the start of metHOTREXATe infusion and MUST continue until the metHOTREXATe serum level is less than 0.05 µmol/L – 0.1 µmol/L (level as per institutional practice). Additional oral alkalinization can be considered as Ural® 2 sachets orally the night before and 2 sachets the morning of high dose metHOTREXATe infusion.
- Before commencing the high dose metHOTREXATe infusion, urinary pH MUST be 7.5 or above (pH 7.5 to 8.0).
- Closely monitor renal function, electrolytes, fluid balance, and weight.
- foliNIc acid MUST start 36 hours after start of metHOTREXATe infusion and MUST continue to be administered until serum metHOTREXATe level is less than 0.05 µmol/L – 0.1 µmol/L (level as per institutional practice).
This regimen contains a medicine where one or more biosimilars may exist. Any biosimilars used have been reviewed by the regulator (Medsafe) and relevant specialists were consulted nationally. Where regulators, in consultation with relevant specialists, have agreed that there are no clinically significant differences in either safety or effectiveness between a biosimilar and originator product, these drugs may be used interchangeably.
Cycle 1 - 35 days
foliNIc acid: MUST start 36 hours after start of metHOTREXATe infusion and MUST continue to be administered until serum metHOTREXATe level is less than 0.05 µmol/L – 0.1 µmol/L (level as per institutional practice).
cytarabine: If renal function reduced from baseline following high dose metHOTREXATe, dose should be reviewed by the haematologist.

Supportive Care Factors
Factor | Value |
---|---|
Antifungal prophylaxis: | Routine antifungal prophylaxis recommended |
Antiviral prophylaxis for herpes virus: | Routine antiviral prophylaxis recommended |
Constipation risk: | Consider prescribing laxatives with this treatment |
Emetogenicity: | Variable |
Folinic acid rescue for high dose methotrexate: | Mandatory |
Gastroprotection: | Gastroprotection is recommended |
Growth factor support: | Recommended for primary prophylaxis |
Hydration: | Routine hydration recommended |
Pneumocystis jirovecii pneumonia (PJP) prophylaxis: | Routine antibiotic prophylaxis recommended |
Antifungal prophylaxis: Inhibition of CYP3A4 by azole antifungals may lead to reduced vinCRISTine clearance and increased toxicities. Strategies to avoid this interaction may include a washout period after azole administration or using a non-azole antifungal for prophylaxis.
Antiviral prophylaxis for hepatitis B virus: Guidance is limited to high-risk anti-cancer medicines. Clinicians will need to assess individual patient risk for other anti-cancer medicines.
Emetogenicity:
- MEDIUM day 1, high dose metHOTREXATe may be highly emetogenic in certain patients.
- LOW day 4.
- MEDIUM day 5.
Gastroprotection: Use an H2 receptor antagonist as a gastroprotective agent for short term use while patient is receiving corticosteroid treatment doses. Do not use proton pump inhibitors with high dose metHOTREXATe.
PJP prophylaxis: If trimethoprim + sulfamethoxazole is used as prophylaxis, it is recommended to withhold at least 48 hours prior to high dose metHOTREXATe administration and until serum metHOTREXATe level is less than 0.05 µmol/L – 0.1µmol/L (as per institutional practice).
