Regimen : Fludarabine Cyclophosphamide Rituximab (FCR-oral) Indication CLL 1st line as per NICE TAG 174 CLL (relapsed) as per NICE TAG 193 Regimen details Day Drug Dose Route Cycle 1 1 Rituximab 375mg/m 2 IV Cycles 2-6 Administration Frequency 2-6* Cyclophosphamide 150mg/m 2 PO 2-6* Fludarabine 24mg/m 2 PO *Some units give chemotherapy on days 1-5 on Cycle 1-clinical decision 1 Rituximab 500mg/m 2 IV 1-5 Cyclophosphamide 150mg/m 2 PO 1-5 Fludarabine 24mg/m 2 PO Rituximab: Patients with a high tumour burden (>25 x 10 9 /L) circulating malignant cells may be at a higher risk of severe cytokine release syndrome. These patients should be managed with extreme caution and should be very closely monitored throughout the first infusion. Consideration should be given to splitting the first Rituximab infusion over two days e.g. 100mg Rituximab in 100ml Sodium Chloride 0.9% on day 1 with the remainder of the Rituximab dose in 500ml Sodium Chloride 0.9% on day 2. Rituximab infusion rate: First infusion: Initiate at 50 mg/hr; if tolerated increase rate by 50mg/hr increments every 30 minutes to a maximum of 400 mg/hr. Subsequent infusions: Second and subsequent infusions of Rituximab can be given safely over 90 minutes if the first infusion was well tolerated.* *Note: this is not a licensed rate of infusion. In frail patients or patients deemed clinically unsuitable for rapid infusion, the licensed administration recommendations should be adhered to i.e. initiate at 100 mg/hr; if tolerated increase by 100 mg/hr increments every 30 minutes to a maximum of 400 mg/hr. Cyclophosphamide: once daily at breakfast (dose rounded to nearest 50mg tablet) Fludarabine: once daily at lunchtime (dose rounded to nearest 10mg tablet) Note: If the oral regime is not tolerated and/or there are concerns regarding absorption, IV route may be used-see ASWCS10 CLL002 FCR (IV)-CLL Every 28 days for 6 cycles Extravasation Rituxumab is neutral (Group 1) Premedication Emetogenicity Additional recommended Pre-Rituximab: Paracetamol 1g PO Chlorphenamine 10mg IV Hydrocortisone 100mg IV (if clinically appropriate) This regimen has mild emetogenic potential refer to local protocol Allopurinol Co-trimoxazole during treatment and for 6 months after finishing Controlled document Document Number Version Number Page 1 of 5
supportive medication Pre-treatment evaluation (i.e. before Cycle 1) Regular investigations (i.e. before Cycle 2 and subsequent cycles) Standard limits for administration to go ahead if blood results not within range, authorisation to administer must be given by prescriber/consultant treatment or count recovery (CD4 count>200), whichever is longer. (In cases of allergy to Cotrimoxazole, consider nebulised Pentamidine 300mg monthly or Dapsone 100mg PO daily). Aciclovir during treatment and for at least 2 months after finishing treatment or count recovery, whichever is longer. All patients who receive Fludarabine should receive irradiated blood products for the duration of chemotherapy treatment and thereafter for life.

Dose modification s Haematologi cal toxicity Renal impairment Hepatic impairment Note: Neutropenia and thrombocytopenia may be due to the disease. Where myelosuppression is deemed treatment-related, the following guidelines apply: If Neutrophils < 1.0 x 10 9 /L or platelets < 75 x 10 9 /L, delay treatment for one week. If counts have not recovered above these levels after two weeks delay, consider proceeding with next course at 50% dose. If Neutrophils < 0.5 x 10 9 /L, delay treatment until count recovery and consider proceeding with next course at 50% dose.

NCI Common toxicity criteria For any grade 3 or 4 non-haematological toxicity (except alopecia), clinical judgement should determine whether to discontinue treatment or to continue treatment at a reduced dose (following recovery to grade 2 toxicity) For any grade autoimmune, neurotoxicity, pneumonitis, or > 2 week delay, discontinue treatment.
