Treatment of B-cell chronic lymphocytic leukaemia (CLL) in adult patients with sufficient bone marrow reserves.
First line treatment with Fludara Sanofi should only be initiated in adult patients with advanced disease, Rai stages III/IV (Binet stage C), or Rai stages I/II (Binet stage A/B) where the patient has disease related symptoms or evidence of progressive disease.
Treatment of B-cell chronic lymphocytic leukaemia (CLL) in adult patients with sufficient bone marrow reserves.
First line treatment with Fludarabine should only be initiated in adult patients with advanced disease, Rai stages III/IV (Binet stage C), or Rai stages I/II (Binet stage A/B) where the patient has disease related symptoms or evidence of progressive disease.
Posology
The recommended dose is 25 mg Fludara Sanofibine phosphate/m² body surface area given daily for 5 consecutive days every 28 days by intravenous route. Each vial is to be made up in 2 ml water for injection. Each ml of the resulting solution will contain 25 mg Fludara Sanofibine phosphate.
The required dose (calculated on the basis of the patient's body surface area) of the reconstituted solution is drawn up into a syringe. For intravenous bolus injection this dose is further diluted in 10 ml sodium chloride 9 mg/ml (0.9%). Alternatively, for infusion, the required dose drawn up in a syringe may be diluted in 100 ml sodium chloride 9 mg/ml (0.9%) and infused over approximately 30 minutes.
The duration of treatment depends on the treatment success and the tolerability of the drug.
In CLL patients, Fludara Sanofi should be administered up to the achievement of best response (complete or partial remission, usually 6 cycles) and then the drug should be discontinued.
Patients with renal impairment
Doses should be adjusted for patients with reduced kidney function. If creatinine clearance is between 30 and 70 ml/min, the dose should be reduced by up to 50% and close haematological monitoring should be used to assess toxicity.
Fludara Sanofi treatment is contraindicated, if creatinine clearance is < 30 ml/min.
Patients with hepatic impairment
No data are available concerning the use of Fludara Sanofi in patients with hepatic impairment. In this group of patients, Fludara Sanofi should be used with caution.
Paediatric population
The safety and efficacy of Fludara Sanofi in children below the age of 18 years have not been established. Therefore, Fludara Sanofi is not recommended for use in children.
Older people
Method of administration
Fludara Sanofi should be administered under the supervision of a qualified physician experienced in the use of antineoplastic therapy.
It is strongly recommended that Fludara Sanofi should be only administered intravenously. No cases have been reported in which paravenously administered Fludara Sanofi led to severe local adverse reactions. However, unintentional paravenous administration must be avoided.
Precautions to be taken before handling the medicinal product

Myelosuppression
Severe bone marrow suppression, notably anaemia, thrombocytopenia and neutropenia, has been reported in patients treated with Fludara Sanofi. In a Phase I intravenous study in adult solid tumour patients, the median time to nadir counts was 13 days (range 3 - 25 days) for granulocytes and 16 days (range 2 - 32 days) for platelets. Most patients had haematologic impairment at baseline either as a result of disease or as a result of prior myelosuppressive therapy.
Cumulative myelosuppression may be seen. While chemotherapy-induced myelosuppression is often reversible, administration of Fludara Sanofibine phosphate requires careful haematologic monitoring.
Fludara Sanofibine phosphate is a potent antineoplastic agent with potentially significant toxic side effects. Patients undergoing therapy should be closely observed for signs of haematologic and non-haematologic toxicity. Periodic assessment of peripheral blood counts is recommended to detect the development of anaemia, neutropenia and thrombocytopenia.
Several instances of trilineage bone marrow hypoplasia or aplasia resulting in pancytopenia, sometimes resulting in death, have been reported in adult patients. The duration of clinically significant cytopenia in the reported cases has ranged from approximately 2 months to approximately 1 year. These episodes have occurred both in previously treated or untreated patients.
As with other cytotoxics, caution should be exercised with Fludara Sanofibine phosphate, when further haematopoietic stem cell sampling is considered.
Autoimmune disorders
Irrespective of any previous history of autoimmune processes or Coombs test status, life-threatening and sometimes fatal autoimmune phenomena have been reported to occur during or after treatment with Fludara Sanofi. The majority of patients experiencing haemolytic anaemia developed a recurrence in the haemolytic process after rechallenge with Fludara Sanofi. Patients treated with Fludara Sanofi should be closely monitored for signs of haemolysis.
Discontinuation of therapy with Fludara Sanofi is recommended in case of haemolysis. Blood transfusion (irradiated, see below) and adrenocorticoid preparations are the most common treatment measures for autoimmune haemolytic anaemia.
Neurotoxicity
The effect of chronic administration of Fludara Sanofi on the central nervous system is unknown. However, patients tolerated the recommended dose, in some studies for relatively long treatment times (for up to 26 courses of therapy).
Patients should be closely observed for signs of neurologic effects.
When used at high doses in dose-ranging studies in patients with acute leukaemia, intravenous Fludara Sanofi was associated with severe neurological effects, including blindness, coma and death. Symptoms appeared from 21 to 60 days from last dose. This severe central nervous system toxicity occurred in 36 % of patients treated intravenously with doses approximately four times greater (96 mg/m²/day for 5 - 7 days) than the recommended dose. In patients treated at doses in the range of the dose recommended for CLL, severe central nervous system toxicity occurred rarely (coma, seizures and agitation) or uncommonly (confusion).
In post-marketing experience neurotoxicity has been reported to occur earlier or later than in clinical trials.
Administration of Fludara Sanofi can be associated with leukoencephalopathy (LE), acute toxic leukoencephalopathy (ATL) or reversible posterior leukoencephalopathy syndrome (RPLS).
These may occur:
- at the recommended dose
o when Fludara Sanofi is given following, or in combination with, medications known to be associated with LE, ATL or RPLS,
o or when Fludara Sanofi is given in patients with other risk factors such as cranial or total body irradiation, Hematopoietic Cell Transplantation, Graft versus Host Disease, renal impairment, or hepatic encephalopathy.
- at doses higher than the recommended dose
LE, ATL or RPLS symptoms may include headache, nausea and vomiting, seizures, visual disturbances such as vision loss, altered sensorium, and focal neurological deficits. Additional effects may include optic neuritis, and papillitis, confusion, somnolence, agitation, paraparesis/ quadriparesis, muscle spasticity and incontinence.
LE/ ATL/ RPLS may be irreversible, life-threatening, or fatal.
Whenever LE, ATL or RPLS is suspected, Fludara Sanofibine treatment should be stopped. Patients should be monitored and should undergo brain imaging, preferably utilizing MRI. If the diagnosis is confirmed, Fludara Sanofibine therapy should be permanently discontinued.
Tumour lysis syndrome
Tumour lysis syndrome has been reported in CLL patients with large tumour burdens. Since Fludara Sanofi can induce a response as early as the first week of treatment, precautions should be taken in those patients at risk of developing this complication, and hospitalisation may be recommended for these patients during the first course of treatment.
Transfusion-associated graft-versus-host disease
Transfusion-associated graft-versus-host disease (reaction by the transfused immunocompetent lymphocytes to the host) has been observed after transfusion of non-irradiated blood in Fludara Sanofi-treated patients. Fatal outcome as a consequence of this disease has been reported with a high frequency. Therefore, to minimise the risk of transfusion-associated graft-versus-host disease, patients who require blood transfusion and who are undergoing, or who have received treatment with Fludara Sanofi should receive irradiated blood only.
Skin cancer
The worsening or flare up of pre-existing skin cancer lesions as well as new onset of skin cancer has been reported in some patients during or after Fludara Sanofi therapy.
Impaired state of health
In patients with impaired state of health, Fludara Sanofi should be given with caution and after careful risk/benefit consideration. This applies especially for patients with severe impairment of bone marrow function (thrombocytopenia, anaemia, and/or granulocytopenia), immunodeficiency or with a history of opportunistic infection.
Renal impairment
The total body clearance of the principle plasma metabolite 2-F-ara-A shows a correlation with creatinine clearance, indicating the importance of the renal excretion pathway for the elimination of the compound. Patients with reduced renal function demonstrated an increased total body exposure (AUC of 2F-ara-A). There are limited clinical data available in patients with impairment of renal function (creatinine clearance < 70 ml/min).
Fludara Sanofi must be administered cautiously in patients with renal insufficiency. In patients with moderate impairment of renal function (creatinine clearance between 30 and 70 ml/min), the dose should be reduced by up to 50% and the patient should be monitored closely. Fludara Sanofi treatment is contraindicated if creatinine clearance is < 30ml/min.
Older people
Pregnancy
Fludara Sanofi should not be used during pregnancy unless clearly necessary (e.g. life-threatening situation, no alternative safer treatment available without compromising the therapeutic benefit, treatment cannot be avoided). It has the potential to cause foetal harm. Prescribers may only consider the use of Fludara Sanofi, if the potential benefits justify the potential risks to the foetus.
Women should avoid becoming pregnant while on Fludara Sanofi therapy.
Women of childbearing potential must be apprised of the potential hazard to the foetus.
Contraception
Women of child-bearing potential or fertile males must take effective contraceptive measures during and at least for 6 months after cessation of therapy.
Vaccination
During and after treatment with Fludara Sanofi vaccination with live vaccines should be avoided.
Retreatment options after initial Fludara Sanofi treatment
A crossover from initial treatment with Fludara Sanofi to chlorambucil for non responders to Fludara Sanofi should be avoided because most patients who have been resistant to Fludara Sanofi have shown resistance to chlorambucil.
Excipients
Each vial Fludara Sanofi 50 mg powder for solution for injection/infusion contains less than 1 mmol sodium (23 mg), i.e. essentially 'sodium-free'.
Myelosuppression

- Hepatic impairment
Fludara Sanofi should be used with caution in patients with hepatic impairment due to the risk of liver toxicity. Fludara Sanofi should be administered only if the perceived benefit outweighs any potential risk. These patients should be closely observed for signs of increased toxicity and the dosing should be modified or the treatment discontinued if indicated.
Neurotoxicity
The effect of chronic administration of fludarabine on the central nervous system is unknown. However, patients tolerated the recommended dose, in some studies for relatively long treatment times (for up to 26 courses of therapy).

Pharmacotherapeutic group: Antineoplastic agents, purine analogues
ATC-code L01B B05
Mechanism of action
Fludara Sanofi contains Fludara Sanofibine phosphate, a water-soluble fluorinated nucleotide analogue of the antiviral agent vidarabine, 9-ß-D-arabinofuranosyladenine (ara-A) that is relatively resistant to deamination by adenosine deaminase.
Fludara Sanofibine phosphate is rapidly dephosphorylated to 2F-ara-A which is taken up by cells and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2F-ara-ATP. This metabolite has been shown to inhibit ribonucleotide reductase, DNA polymerase α/δ and ε, DNA primase and DNA ligase thereby inhibiting DNA synthesis. Furthermore, partial inhibition of RNA polymerase II and consequent reduction in protein synthesis occur.
While some aspects of the mechanism of action of 2F-ara-ATP are as yet unclear, it is assumed that effects on DNA, RNA and protein synthesis all contribute to inhibition of cell growth with inhibition of DNA synthesis being the dominant factor. In addition, in vitro studies have shown that exposure of CLL lymphocytes to 2F-ara-A triggers extensive DNA fragmentation and cell death characteristic of apoptosis.
Clinical efficacy and safety
A phase III trial in patients with previously untreated B-chronic lymphocytic leukaemia comparing treatment with Fludara Sanofi vs. chlorambucil (40mg / m² q4 weeks) in 195 and 199 patients respectively showed the following outcome: statistically significant higher overall response rates and complete response rates after 1st line treatment with Fludara Sanofi compared to chlorambucil (61.1% vs. 37.6% and 14.9% vs. 3.4%, respectively); statistically significant longer duration of response (19 vs. 12.2 months) and time to progression (17 vs. 13.2 months) for the patients in the Fludara Sanofi group. The median survival of the two patient groups was 56.1 months for Fludara Sanofi and 55.1 months for chlorambucil, a non-significant difference was also shown with performance status. The proportion of patients reported to have toxicities were comparable between Fludara Sanofi patients (89.7%) and chlorambucil patients (89.9%). While the difference in the overall incidence of haematological toxicities was not significant between the two treatment groups, significantly greater proportions of Fludara Sanofi patients experienced white blood cell (p=0.0054) and lymphocyte (p=0.0240) toxicities than chlorambucil patients. The proportions of patients who experienced nausea, vomiting, and diarrhoea were significantly lower for Fludara Sanofi patients (p<0.0001, p<0.0001, and p=0.0489, respectively) than chlorambucil patients. Toxicities of the liver were also reported for significantly (p=0.0487) less proportions of patients in the Fludara Sanofi group than in the chlorambucil group.
Patients who initially respond to Fludara Sanofi have a chance of responding again to Fludara Sanofi monotherapy.
A randomised trial of Fludara Sanofi vs. cyclophosphamide, adriamycin and prednisone (CAP) in 208 patients with CLL Binet stage B or C revealed the following results in the subgroup of 103 previously treated patients: the overall response rate and the complete response rate were higher with Fludara Sanofi compared to CAP (45% vs. 26% and 13% vs. 6%, respectively); response duration and overall survival were similar with Fludara Sanofi and CAP. Within the stipulated treatment period of 6 months the number of deaths was 9 (Fludara Sanofi) vs. 4 (CAP).
Post-hoc analyses using only data of up to 6 months after start of treatment revealed a difference between survival curves of Fludara Sanofi and CAP in favour of CAP in the subgroup of pretreated Binet stage C patients.

In addition, in vitro studies have shown that exposure of CLL lymphocytes to 2F-ara-A triggers extensive DNA fragmentation and cell death characteristic of apoptosis.
Clinical efficacy and safety
A phase III trial in patients with previously untreated B-chronic lymphocytic leukaemia comparing treatment with Fludarabine vs. chlorambucil (40mg / m² q4 weeks) in 195 and 199 patients respectively showed the following outcome: statistically significant higher overall response rates and complete response rates after 1st line treatment with Fludarabine compared to chlorambucil (61.1% vs. 37.6% and 14.9% vs. 3.4%, respectively); statistically significant longer duration of response (19 vs. 12.2 months) and time to progression (17 vs. 13.2 months) for the patients in the Fludarabine group. The median survival of the two patient groups was 56.1 months for Fludarabine and 55.1 months for chlorambucil, a non-significant difference was also shown with performance status. The proportion of patients reported to have toxicities were comparable between Fludarabine patients (89.7%) and chlorambucil patients (89.9%). While the difference in the overall incidence of haematological toxicities was not significant between the two treatment groups, significantly greater proportions of Fludarabine patients experienced white blood cell (p=0.0054) and lymphocyte (p=0.0240) toxicities than chlorambucil patients. The proportions of patients who experienced nausea, vomiting, and diarrhoea were significantly lower for Fludarabine patients (p<0.0001, p<0.0001, and p=0.0489, respectively) than chlorambucil patients. Toxicities of the liver were also reported for significantly (p=0.0487) less proportions of patients in the Fludarabine group than in the chlorambucil group.
Patients who initially respond to Fludarabine have a chance of responding again to Fludarabine monotherapy.
A randomised trial of Fludarabine vs. cyclophosphamide, adriamycin and prednisone (CAP) in 208 patients with CLL Binet stage B or C revealed the following results in the subgroup of 103 previously treated patients: the overall response rate and the complete response rate were higher with Fludarabine compared to CAP (45% vs. 26% and 13% vs. 6%, respectively); response duration and overall survival were similar with Fludarabine and CAP. Within the stipulated treatment period of 6 months the number of deaths was 9 (Fludarabine) vs. 4 (CAP).
Post-hoc analyses using only data of up to 6 months after start of treatment revealed a difference between survival curves of Fludarabine and CAP in favour of CAP in the subgroup of pretreated Binet stage C patients.
Plasma and urinary pharmacokinetics of Fludara Sanofibine (2F-ara-A)
The pharmacokinetics of Fludara Sanofibine (2F-ara-A) have been studied after intravenous administration by rapid bolus injection and short-term infusion as well as following continuous infusion and after peroral dosing of Fludara Sanofibine phosphate (Fludara Sanofi, 2F-ara-AMP).
No clear correlation was found between 2F-ara-A pharmacokinetics and treatment efficacy in cancer patients.
However, occurrence of neutropenia and haematocrit changes indicated that the cytotoxicity of Fludara Sanofibine phosphate depresses the haematopoiesis in a dose-dependent manner.
Distribution and metabolism
2F-ara-AMP is a water-soluble prodrug of Fludara Sanofibine (2F-ara-A), which is rapidly and quantitatively dephosphorylated in the human organism to the nucleoside Fludara Sanofibine (2F-ara-A).
Another metabolite, 2F-ara-hypoxanthine, which represents the major metabolite in the dog, was observed in humans only to a minor extent.
After single dose infusion of 25 mg 2F-ara-AMP per m² to CLL patients for 30 minutes 2F-ara-A reached mean maximum concentrations in the plasma of 3.5 - 3.7 μM at the end of the infusion. Corresponding 2F-ara-A levels after the fifth dose showed a moderate accumulation with mean maximum levels of 4.4 - 4.8 µM at the end of infusion. During a 5-day treatment schedule 2F-ara-A plasma trough levels increased by a factor of about 2. An accumulation of 2F-ara-A over several treatment cycles can be excluded. Postmaximum levels decayed in three disposition phases with an initial half-life of approximately 5 minutes, an intermediate half-life of 1 - 2 hours and a terminal half-life of approximately 20 hours.
An interstudy comparison of 2F-ara-A pharmacokinetics resulted in a mean total plasma clearance (CL) of 79 ± 40 ml/min/m² (2.2 ± 1.2 ml/min/kg) and a mean volume of distribution (Vss) of 83 ± 55 l/m² (2.4 ± 1.6 l/kg). Data showed a high interindividual variability. After intravenous and peroral administration of Fludara Sanofibine phosphate plasma levels of 2F-ara-A and areas under the plasma level time curves increased linearly with the dose, whereas half-lives, plasma clearance and volumes of distribution remained constant independent of the dose indicating a dose linear behaviour.
Elimination
2F-ara-A elimination is largely by renal excretion. 40 to 60 % of the administered intravenous dose was excreted in the urine. Mass balance studies in laboratory animals with ³H-2F-ara-AMP showed a complete recovery of radio-labelled substances in the urine.
Characteristics in patients
Individuals with impaired renal function exhibited a reduced total body clearance, indicating the need for a dose reduction. In vitro investigations with human plasma proteins revealed no pronounced tendency of 2F-ara-A protein binding.
Cellular pharmacokinetics of Fludara Sanofibine triphosphate
2F-ara-A is actively transported into leukaemic cells, whereupon it is rephosphorylated to the monophosphate and subsequently to the di- and triphosphate. The triphosphate 2F-ara-ATP is the major intracellular metabolite and the only metabolite known to have cytotoxic activity. Maximum 2F-ara-ATP levels in leukaemic lymphocytes of CLL patients were observed at a median of 4 hours and exhibited a considerable variation with a median peak concentration of approximately 20 µM. 2F-ara-ATP levels in leukaemic cells were always considerably higher than maximum 2F-ara-A levels in the plasma indicating an accumulation at the target sites. In-vitro incubation of leukaemic lymphocytes showed a linear relationship between extracellular 2F-ara-A exposure (product of 2F-ara-A concentration and duration of incubation) and intracellular 2F-ara-ATP enrichment. 2F-ara-ATP elimination from target cells showed median half-life values of 15 and 23 hours.

Systemic toxicity
In acute toxicity studies, single doses of Fludara Sanofibine phosphate produced severe intoxication symptoms or death at dosages about two orders of magnitude above the therapeutic dose. As expected for a cytotoxic compound, the bone marrow, lymphoid organs, gastrointestinal mucosa, kidneys and male gonads were affected. In patients, severe side effects were observed closer to the recommended therapeutic dose (factor 3 to 4) and included severe neurotoxicity partly with lethal outcome.
Systemic toxicity studies following repeated administration of Fludara Sanofibine phosphate showed also the expected effects on rapidly proliferating tissues above a threshold dose. The severity of morphological manifestations increased with dose levels and duration of dosing and the observed changes were generally considered to be reversible. In principle, the available experience from the therapeutic use of Fludara Sanofi points to a comparable toxicological profile in humans, although additional undesirable effects such as neurotoxicity were observed in patients.
Embryotoxicity
The results from intravenous animal embryotoxicity studies in rats and rabbits indicated an embryolethal and teratogenic potential of Fludara Sanofibine phosphate as manifested in skeletal malformations, foetal weight loss and post implantation loss. In view of the small safety margin between the teratogenic doses in animals and the human therapeutic dose as well as in analogy to other antimetabolites which are assumed to interfere with the process of differentiation, the therapeutic use of Fludara Sanofi is associated with a relevant risk of teratogenic effects in humans.
Genotoxic potential, tumorigenicity
Fludara Sanofibine phosphate has been shown, to cause DNA-damage in a sister chromatid exchange test, to induce chromosomal aberrations in an in vitro cytogenetic assay and to increase the rate of micronuclei in the mouse micronucleus test in vivo, but was negative in gene mutation assays and in the dominant lethal test in male mice. Thus, the mutagenic potential was demonstrated in somatic cells but could not be shown in germ cells.
The known activity of Fludara Sanofibine phosphate at the DNA-level and the mutagenicity test results form the basis for the suspicion of a tumorigenic potential. No animal studies which directly address the question of tumorigenicity have been conducted, because the suspicion of an increased risk of second tumours due to Fludara Sanofi therapy can exclusively be verified by epidemiological data.
Local tolerance
According to the results from animal experiments following intravenous administration of Fludara Sanofibine phosphate, no remarkable local irritation has to be expected at the injection site. Even in case of misplaced injections, no relevant local irritation was observed after paravenous, intraarterial, and intramuscular administration of an aqueous solution containing 7.5 mg Fludara Sanofibine phosphate/ml.
The similarity in nature of the observed lesions in the gastrointestinal tract after intravenous or intragastric dosing in animal experiments supports the assumption that the Fludara Sanofibine phosphate induced enteritis is a systemic effect.
