LYM NHL B-cell PCNSL Relapsed - R-IE [RITUximab, IFOSFamide and etoposide]

Treatment Overview

Usually 4 cycles. Assess patient after cycle 2; if in complete remission (CR), partial remission (PR) or has stable disease (SD) give 2 more cycles R-IE (4 cycles in total). 


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 - 21 days

Cycle length:
21

RITUximab, first dose:

  • Consider withholding routine anti-hypertensives for 12 hours prior to first RITUximab dose.
  • For patients at high risk of infusion-related reaction, consider additional pre-medications such as an extra antihistamine dose the day before, an H2 receptor antagonist and montelukast.

filgrastim:

  • Give 5 microgram/kg subcutaneously ONCE daily from day 4 until neutrophil recovery past the nadir, or as per institutional policy for prophylaxis.
  • If for stem cell harvest, mobilise as per institutional practice.

Cycles 2 to 4 - 21 days

Cycle length:
21

RITUximab, subsequent doses:

  • Consider administering corticosteroid premedication prior to RITUximab if previous doses not well tolerated or if clinically indicated as per institutional practice.

filgrastim:

  • Give 5 microgram/kg subcutaneously ONCE daily from day 4 until neutrophil recovery past the nadir, or as per institutional policy for prophylaxis.
