A - Regimen Name

FC Regimen
Fludarabine-Cyclophosphamide


Disease Site
Hematologic - Leukemia - Chronic Lymphocytic (CLL)

Intent
Palliative

Regimen Category
Evidence-Informed :

Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR).  Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.


Rationale and Uses

Second-line treatment in patients with CLL
 

 
B - Drug Regimen

fludarabine

(Round to nearest 2.5 mg)
25 mg /m² IV Days 1-3 *
cyclophosphamide

(Round to nearest 10 mg)
250 mg /m² IV Days 1-3 *

C - Cycle Frequency

REPEAT EVERY 28 DAYS

For 6 cycles in the absence of disease progression or unacceptable toxicity

 
D - Premedication and Supportive Measures

Antiemetic Regimen:

Moderate

Other Supportive Care:

Also refer to CCO Antiemetic Summary

  • Consider prophylactic growth factor support, antiviral and PCP prophylaxis (according to local practice).
  • If high volume disease (e.g. WBC > 25 x 109/L),  consider prophylaxis for tumour lysis
 
E - Dose Modifications

Doses should be modified according to the protocol by which the patient is being treated

Dosage with toxicity

Suggested dose levels for fludarabine are 25 mg/m2 , 20 mg/m2  and 15 mg/m2 .
Suggested dose levels for cyclophosphamide are 250 mg/m2 , 200 mg/m2  and 150 mg/m2 .
