Cycle 1

Drug Dose Route Day
Rituximab * 375 mg/m2 IV infusion 0
Fludarabine 25 mg/m2 IV infusion *** 1 to 3
CYCLOPHOSPHamide 250 mg/m2 IV infusion *** 1 to 3

Cycle 2 to 6

Drug Dose Route Day
Rituximab 500 mg/m2 IV infusion ** 1
Fludarabine 25 mg/m2 IV infusion *** 1 to 3
CYCLOPHOSPHamide 250 mg/m2 IV infusion *** 1 to 3

* The dose of rituximab can be split over 2 days or be administered later in the cycle.

** From dose 2 onwards, rituximab may be administered subcutaneously as a flat dose of 1,600 mg. Note: the 1,600 mg subcutaneous product is currently not available in Australia. For more information see the Chronic lymphocytic leukaemia subcutaneous rituximab  document.

*** For oral dosing of fludarabine and cyclophosphamide refer to the evidence section.

Frequency:
28 days 
Cycles:
6. Depending on response and toxicity less cycles may be given.
Notes:

This is a very immunosuppressive therapy; caution required in pre-treated patients, those with pre-existing cytopenias, those with a history of opportunistic infections and the elderly.

Concomitant treatment with steroids (excluding those used as antiemetics and rituximab premedication) should be avoided where possible due to the heightened risk of opportunistic infections.

It is the consensus of the Haematology Reference Committee that a 5HT3 antagonist should be given on each day of treatment, all patients should receive antiviral and PJP prophylaxis for the duration of treatment and a minimum of 3 to 6 months subsequently and antifungal prophylaxis is not routine.

Drug status:

Rituximab: (PBS authority)

Rituximab SC: TGA registered but not PBS listed.

Fludarabine and cyclophosphamide are available on the PBS general schedule

Cost:
~ $1,520 per cycle "How this cost is calculated"

The cost displayed on the protocol is intended as rudimentary guide only for the Australian context.

The cost includes anti-cancer drugs only (not antiemetics, supportive medications or consumables), unless otherwise indicated.

Drug unit costs are taken directly from the Pharmaceutical Benefits Scheme (PBS) website (www.pbs.gov.au), MIMS Online and other sources. These costs are reviewed and updated on eviQ at 6 monthly intervals.

Where there are differing unit costs based on vial sizes and tablet strengths, the mean unit cost is used. The cost of oral continuous therapy is based on a 28 day month.

The protocol cost is derived from drug dose calculations based upon a default body surface area (BSA) of 1.8 m2; weight of 75 kg; and creatinine clearance of 75 mL/min.

One off loading doses and ongoing maintenance doses are not included in protocol cost calculations.

The cost displayed is the actual drug cost and does not necessarily reflect the cost incurred by the patient as many anti-cancer drugs are reimbursed on the PBS.

The supportive therapies (e.g. antiemetics, premedications, etc.), infusion times, diluents, volumes and routes of administration, if included, are listed as defaults. They may vary between institutions and can be substituted to reflect individual institutional policy.

Antiemetics if included in the treatment schedule are based upon recommendations from national and international guidelines. These are defaults only and may be substituted to reflect individual institutional policy. Select here for recommended doses of alternative antiemetics.

Evidence for dose modifications is limited, and the recommendations made on eviQ are intended as a guide only. They are generally conservative with an emphasis on safety. Any dose modification should be based on clinical judgement, and the individual patient’s situation including but not limited to treatment intent (curative vs palliative), the anti-cancer regimen (single versus combination therapy versus chemotherapy versus immunotherapy), biology of the cancer (site, size, mutations, metastases), other treatment related side effects, additional co-morbidities, performance status and patient preferences. Suggested dose modifications are based on clinical trial findings, product information and reference committee consensus. Non-haematological gradings are based on Common Terminology Criteria for Adverse Events (CTCAE) unless otherwise specified. Renal and hepatic dose modifications have been standardised where possible. For more information see dosing considerations & disclaimer.

Note: All dose reductions are calculated as a percentage of the starting dose

Haematological toxicity
ANC x 109/L (pre-treatment blood test)
Less than 1.0 or previous episode of febrile neutropenia Delay treatment until recovery and consider adding G-CSF for subsequent cycles.
Consider reducing fludarabine by 25% for repeat grade 3 or 4 neutropenia (on Day 1 of cycle).
Platelets x 109/L (pre-treatment blood test)
Less than 75 Delay treatment until recovery. No dose reduction if decreased platelet count is due to disease.
Consider reducing fludarabine by 25% for repeat grade 3 or 4 thrombocytopenia (on Day 1 of cycle).
Renal impairment
Creatinine clearance (mL/min)
30 - 60 Reduce fludarabine to 20mg/m2
less than 30 Use alternative treatment

Note: Landmark trials excluded patients with CrCl <70mL/min.  ​Other clinical trials have used FCR without dose reduction with CrCl as low as 40mL/min, however increased toxicity may be expected.  There are few data on efficacy/toxicity with dose reduction due to CrCl for this regimen.

Hepatic impairment
Hepatic dysfunction
No dose modifications recommended
Peripheral neuropathy
Consider delaying or discontinuing fludarabine if neurotoxicity occurs

Drug interactions in eviQ protocols are under review and being updated to align with current literature. Further site-wide updates and changes will occur in due course. References & Disclaimer

The drug interactions shown below are not an exhaustive list. For a more comprehensive list and for detailed information on specific drug interactions and clinical management, please refer to the specific drug product information and the following key resources:  

Cyclophosphamide
  Interaction Clinical management
CYP3A4 inducers (e.g. carbamazepine, phenytoin, phenobarbitone, rifampicin, St John’s wort etc.) Increased toxicity of cyclophosphamide possible due to increased conversion to active (and inactive) metabolites Avoid combination or monitor for cyclophosphamide toxicity
CYP3A4 inhibitors (e.g. aprepitant, azole antifungals, clarithromycin, erythromycin, grapefruit juice, ritonavir etc.) Reduced efficacy of cyclophosphamide possible due to decreased conversion to active (and inactive) metabolites Avoid combination or monitor for decreased clinical response to cyclophosphamide
Amiodarone Possible additive pulmonary toxicity with high-dose cyclophosphamide (i.e. doses used prior to stem cell transplant; 60 mg/kg daily or 120 to 270 mg/kg over a few days) Avoid combination or monitor closely for pulmonary toxicity
Allopurinol, hydrochlorothiazide, indapamide Delayed effect. Increased risk of bone marrow depression; probably due to reduced clearance of active metabolites of cyclophosphamide Avoid combination, consider alternative antihypertensive therapy or monitor for myelosuppression
Ciclosporin Reduced efficacy of ciclosporin due to reduced serum concentration Monitor ciclosporin levels; adjust dosage as appropriate; monitor response to ciclosporin
Suxamethonium Prolonged apnoea due to marked and persistent inhibition of cholinesterase by cyclophosphamide Alert the anaesthetist if a patient has been treated with cyclophosphamide within ten days of planned general anaesthesia
Fludarabine
  Interaction Clinical management
Dipyridamole Reduced efficacy of fludarabine possible due to inhibition of adenosine uptake Avoid combination or monitor for decreased clinical response to fludarabine
Rituximab
  Interaction Clinical management
Antihypertensives Additive hypotensive effect Consider withholding antihypertensive medications 12 hours prior to the rituximab infusion
General
  Interaction Clinical management
Warfarin Anti-cancer drugs may alter the anticoagulant effect of warfarin. Monitor INR regularly and adjust warfarin dosage as appropriate; consider alternative anticoagulant.
Direct oral anticoagulants (DOACs) e.g. apixaban, rivaroxaban, dabigatran

Interaction with both CYP3A4 and P-gp inhibitors /inducers.

DOAC and anti-cancer drug levels may both be altered, possibly leading to loss of efficacy or toxicity (i.e. increased bleeding).

Apixaban: avoid concurrent use with strong CYP3A4 and P‑gp inhibitors. If treating VTE, avoid use with strong CYP3A4 and P‑gp inducers. 

Rivaroxaban: avoid concurrent use with strong CYP3A4 and P‑gp  inhibitors.

Dabigatran: avoid combination with strong P‑gp inducers and inhibitors.

If concurrent use is unavoidable, monitor closely for efficacy/toxicity of both drugs.
Digoxin Anti-cancer drugs can damage the lining of the intestine; affecting the absorption of digoxin. Monitor digoxin serum levels; adjust digoxin dosage as appropriate.
Antiepileptics Both altered antiepileptic and anti-cancer drug levels may occur, possibly leading to loss of efficacy or toxicity. Where concurrent use of an enzyme-inducing antiepileptic cannot be avoided, monitor antiepileptic serum levels for toxicity, as well as seizure frequency for efficacy; adjust dosage as appropriate.
Also monitor closely for efficacy of the anti-cancer therapy.
Antiplatelet agents and NSAIDs Increased risk of bleeding due to treatment related thrombocytopenia. Avoid or minimise combination.
If combination deemed essential, (e.g. low dose aspirin for ischaemic heart disease) monitor for signs of bleeding.
Serotonergic drugs, including selective serotonin reuptake inhibitors (SSRIs e.g. paroxetine) and serotonin noradrenaline reuptake inhibitors (SNRIs e.g. venlafaxine) Increased risk of serotonin syndrome with concurrent use of 5-HT3 receptor antagonists (e.g. palonosetron, ondansetron, granisetron, tropisetron, dolasetron, etc.) Avoid combination.
If combination is clinically warranted, monitor for signs and symptoms of serotonin syndrome (e.g. confusion, agitation, tachycardia, hyperreflexia).
For more information link to TGA Medicines Safety Update
Vaccines Diminished response to vaccines and increased risk of infection with live vaccines. Live vaccines (e.g. BCG, MMR, zoster and varicella) are contraindicated in patients on immunosuppressive therapy. Use with caution in patients on non-immunosuppressive therapy.
For more information; refer to the recommended schedule of vaccination for cancer patients, as outlined in the Australian Immunisation Handbook

The chemoimmunotherapy combination of fludarabine, cyclophosphamide and rituximab (FCR or R-FC) is recommended for young or fit, elderly patients with previously untreated chronic lymphocytic leukaemia (CLL).

The German CLL study group CLL8 study, a phase 3 randomised controlled trial comparing the combination of rituximab, fludarabine and cyclophosphamide (R-FC, n=408 patients) to FC alone (n=409), demonstrated superior response rates (Table 1), progression-free survival and overall survival for patients who received R-FC.r The overall response rate (ORR) was 90% (FCR) compared to 80% (FC, p<0.0001) including a complete response rate (CR) of 44% (FCR) versus 22% (FC, p<0.0001). The hazard ratios for PFS and OS were 0.56 [95%CI: 0.46 – 0.69] and 0·67 [0·48–0·92] respectively.

The MD Anderson group updated their outcomes with the FCR regimen.r The 6-year median overall survival of 77% and failure-free survival of 51% suggest that a significant proportion of patients may achieve long-lasting remissions with this chemoimmunotherapy regimen. Both studies demonstrated that patients with 17p deletions were less likely to achieve long-lasting responses following either FC or FCR.

The GCLLSG CLL10 confirms the superiority of FCR over bendamustine-rituximab as first-line therapy in fit patients, with higher CR rate (40% vs 31%) and improved median PFS (55 vs 42 months), though no difference in overall survival.r  However in subgroup analysis of age > 65, the difference in PFS was not evident.

The ECOG-ACRIN E1912 randomised control trial compared 6 cycles of ibrutinib and rituximab followed by ongoing ibrutinib until progression or toxicity with FCR.  In this FCR demonstrated statistically inferior 3-year PFS (73% vs 89%) and OS (92% vs 99%), most marked in patients with unmutated IgHV.r

FCR may also be used in the relapsed CLL setting. The REACH studyr demonstrated superior responses and progression-free survival of FCR over FC in patients with CLL in first relapse who had received prior fludarabine or alkylator-based therapy. Patients who had received prior FC or rituximab were excluded. There was no statistical difference in overall survival between the two groups at a median follow-up time of 25 months.r

The MD Anderson group updated their experience with FCR in a phase 2 single arm study of FCR for patients with relapsed CLL. This study demonstrated good responses (ORR 74% and CR 30% for all patients) and progression-free survival (21 months) following administration of FCR in this population. CLL patients who had received more than 3 prior treatments, were fludarabine-refractory, or patients with chromosome 17 abnormalities experienced suboptimal responses and short progression-free survival.r

A meta-analysis conducted by Nunes et al. comparing FC and FCR in patients with CLL, the PFS was 32.8 months in the FC group and 51.8 months in the FCR group. The difference between the two groups was statistically significant (p<0.05).r

The subgroup analysis conducted by Thompson et al. found long-term disease-free survival after FCR therapy in patients with mutated immunoglobulin heavy chain variable (IGHV) gene (IGHV-M). The original patient cohort (n=300) who received FCR in the phase 2 study was reviewed to identify long-term disease-free survivors.r

Median PFS was not reached (NR) for patients with IGHV-M and 4.2 years for patients with IGHV-UM (P<.001). Progression-free survival at 12.8 years was 53.9% for patients with IGHV-M versus 8.7% for patients with unmutated IGHV (IGHV-UM). Furthermore, 50.7% of patients with IGHV-M who achieved MRD-negativity posttreatment had a PFS of 79.8% at 12.8 years. No relapses occurred beyond 10.4 years in 42 patients (total follow-up 105.4 patient-years) with IGHV-M, which resulted in a plateau on the PFS curve.r

Although IGHV-UM patients had inferior PFS compared to the IGHV-M patients, 9 of 126 patients with IGHV-UM remained in clinical remission beyond 10 years. The difference in PFS translated into a significant survival advantage for patients with IGHV-M. Patients who achieved MRD-negativity by PCR at completion of treatment had prolonged PFS of a median of 13.7 years compared to patients who remained MRD-positive with a median PFS of 4.0 years. Furthermore, patients with IGHV-M who were PCR negative at end-of-treatment had a 12.8-year PFS of 79.8% as opposed to a PFS of 36.9% if patients were MRD-positive.r

The median overall survival (OS) for the total cohort was 12.7 years. Survival was significantly inferior for patients with IGHV-UM compared with IGHV-M (median, 9.4 years vs NR and 12.8-years, 32.2% vs 65.5%; P < .001). Also, B2-microglobulin (B2M) ≥4.0 was predictive of inferior survival regardless of whether patients had IGHV mutation or not (IGHV-UM P = .002 and IGHV-M P = .011).r

MRD-negativity was associated with superior long-term survival in patients with IGHV-M only. A survival of 87.2% for MRD-negative patients and 56.5% for MRD-positive patients was observed at 12.8 years. MRD status did not affect IGHV-UM patients according to MRD status (P = .146).r

Toxicity

In the German CLL8 study 76% of patients experienced at least one grade 3 or 4 adverse event following chemoimmunotherapy with FCR (table 2). The majority of these events were haematological toxicity (56%) with neutropenia (34%) being most common. Chemoimmunotherapy with FCR was associated with a higher rate of grade 3 or 4 neutropenia compared to FC (34% versus 21% respectively, P<0.0001); however, the rates of severe infections were similar (25% versus 21%, p=0.18).

In the GCLLSG CLL10 study FCR was more toxic than bendamustine-rituximab with increased neutropenia (84% vs. 59%) and severe infections (39% vs. 25%).r  In the ECOG-ACRIN E1912 trial grade 3+ infections were higher in the FCR arm (20%) than ibrutinib-rituximab.r

Similar rates of grade 3 or 4 complications were noted in the REACH study (Table 3).r Almost all patients experienced grade 3 or 4 neutropenia during the study with a slightly higher incidence in the FCR arm (FCR 89% vs. FC 84%). Despite this, the overall incidence of infections (FC 51% and FCR 49%) and grade 3 or 4 infections (FC 19% and FCR 18%) did not differ between arms. Fatal adverse events occurred in 10% (FC) and 14% (FCR) of patients, mostly related to serious infections. In the phase 2 MD Anderson trial for relapsed CLL, patients older than 70 years with relapsed CLL were less likely to complete therapy and had a higher incidence of serious infections and myelosuppression.r

This regimen should be used with caution in elderly patients and patients with co-morbidities including reduced creatinine clearance.  Landmark trials demonstrating efficacy and survival for the FCR regimen excluded patients with CrCl <70 mL/min.rr  Other clinical trials have included patients with creatinine clearance as low as 40 mL/min without dose modification.r  There are no clear data on the efficacy and toxicity when modifying dose due to renal dysfunction.

In a more recent trial conducted by Benjamini et al., the risk of second cancers was found to be 2.38 times higher than the expected risk in the general population (40% had other cancers before and 28% after FCR). Second cancer risk after frontline FCR is mainly due to high rates of acute myeloid leukaemia / myelodysplastic syndrome (t-AML/MDS) (5.1%) and Richter transformation (RT) (9%) while solid tumors were not increased. The survival of affected patients is shorter.r

Oral FCR

Early studies incorporating single agent fludarabine confirmed similar pharmokinetic data for IV fludarabine 25mg and oral fludarabine 40mg. Retrospective reviews of studies in fludarabine and cyclophosphamide demonstrate comparable efficacy, however increased gastrointestinal toxicity when substituting oral fludarabine.r  With these data oral FCR has been incorporated into clinical trials, though there are no head-to-head trials of IV and oral FCR. The ARCTIC and ADMIRE studies used the regimen of fludarabine 24 mg/m2 daily and cyclophosphamide 150 mg/m2 daily for 5 days with similar outcomes to historical IV FCR.rr  The CLL2007 SA studyr used oral fludarabine 40 mg/m2 and cyclophosphamide 250 mg/m2 for 3 days and ICORG 07-01 studyr allowed IV or oral formulations, however cycle numbers were limited to 4, and direct comparisons can not be made.  Oral fludarabine and cyclophosphamide utilising modified dosing may be considered.
