Generic Name: Fludarabine phosphate
Dosage Form: injection, powder, lyophilized, for solution
FOR INTRAVENOUS USE ONLY
Fludara FOR INJECTION should be administered under the supervision of a qualified physician experienced in the use of antineoplastic therapy. Fludara FOR INJECTION can severely suppress bone marrow function. When used at high doses in dose-ranging studies in patients with acute leukemia, Fludara FOR INJECTION was associated with severe neurologic effects, including blindness, coma, and death. This severe central nervous system toxicity occurred in 36% of patients treated with doses approximately four times greater (96 mg/m2/day for 5-7 days) than the recommended dose. Similar severe central nervous system toxicity, including coma, seizures, agitation and confusion, has been reported in patients treated at doses in the range of the dose recommended for chronic lymphocytic leukemia.
Instances of life-threatening and sometimes fatal autoimmune phenomena such as hemolytic anemia, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evans syndrome, and acquired hemophilia have been reported to occur after one or more cycles of treatment with Fludara FOR INJECTION. Patients undergoing treatment with Fludara FOR INJECTION should be evaluated and closely monitored for hemolysis.
In a clinical investigation using Fludara FOR INJECTION in combination with pentostatin (deoxycoformycin) for the treatment of refractory chronic lymphocytic leukemia (CLL), there was an unacceptably high incidence of fatal pulmonary toxicity. Therefore, the use of Fludara FOR INJECTION in combination with pentostatin is not recommended.
Fludara FOR INJECTION contains Fludarabine phosphate, a fluorinated nucleotide analog of the antiviral agent vidarabine, 9-β-D-arabinofuranosyladenine (ara-A) that is relatively resistant to deamination by adenosine deaminase. Each vial of sterile lyophilized solid cake contains 50 mg of the active ingredient Fludarabine phosphate, 50 mg of mannitol, and sodium hydroxide to adjust pH to 7.7. The pH range for the final product is 7.2-8.2. Reconstitution with 2 mL of Sterile Water for Injection, USP, results in a solution containing 25 mg/mL of Fludarabine phosphate intended for intravenous administration.
The chemical name for Fludarabine phosphate is 9H-Purin-6-amine, 2-fluoro-9-(5-0-phosphono-β-D-arabino-furanosyl) (2-fluoro-ara-AMP). The molecular formula of Fludarabine phosphate is C10H13FN5O7P (MW 365.2) and the structure is:
Fludara - Clinical Pharmacology
Fludarabine phosphate is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro-ara-ATP. This metabolite appears to act by inhibiting DNA polymerase alpha, ribonucleotide reductase and DNA primase, thus inhibiting DNA synthesis. The mechanism of action of this antimetabolite is not completely characterized and may be multi-faceted.
Phase I studies in humans have demonstrated that Fludarabine phosphate is rapidly converted to the active metabolite, 2-fluoro-ara-A, within minutes after intravenous infusion. Consequently, clinical pharmacology studies have focused on 2-fluoro-ara-A pharmacokinetics. After the five daily doses of 25 mg 2-fluoro-ara-AMP/m2 to cancer patients infused over 30 minutes, 2-fluoro-ara-A concentrations show a moderate accumulation. During a 5-day treatment schedule, 2-fluoro-ara-A plasma trough levels increased by a factor of about 2. The terminal half-life of 2-fluoro-ara-A was estimated as approximately 20 hours. In vitro, plasma protein binding of Fludarabine ranged between 19% and 29%.
A correlation was noted between the degree of absolute granulocyte count nadir and increased area under the concentration x time curve (AUC).
Special PopulationsPediatric Patients
Limited pharmacokinetic data for Fludara FOR INJECTION are available from a published study of children (ages 1-21 years) with refractory acute leukemias or solid tumors (Children’s Cancer Group Study 097). When Fludara FOR INJECTION was administered as a loading dose over 10 minutes immediately followed by a 5-day continuous infusion, steady-state conditions were reached early.Patients with Renal Impairment
The total body clearance of the principal metabolite 2-fluoro-ara-A correlated with the creatinine clearance, indicating the importance of the renal excretion pathway for the elimination of the drug. Renal clearance represents approximately 40% of the total body clearance. Patients with creatinine clearance 30-79 mL/min should have their Fludara FOR INJECTION dose reduced and be monitored closely for excessive toxicity. Due to insufficient data, Fludara FOR INJECTION should not be administered to patients with creatinine clearance less than 30 mL/min. (See DOSAGE AND ADMINISTRATION section).
Two single-arm, open-label studies of Fludara FOR INJECTION have been conducted in adult patients with CLL refractory to at least one prior standard alkylating-agent containing regimen. In a study conducted by M.D. Anderson Cancer Center (MDAH), 48 patients were treated with a dose of 22-40 mg/m2 daily for 5 days every 28 days. Another study conducted by the Southwest Oncology Group (SWOG) involved 31 patients treated with a dose of 15-25 mg/m2 daily for 5 days every 28 days. The overall objective response rates were 48% and 32% in the MDAH and SWOG studies, respectively. The complete response rate in both studies was 13%; the partial response rate was 35% in the MDAH study and 19% in the SWOG study. These response rates were obtained using standardized response criteria developed by the National Cancer Institute CLL Working Group and were achieved in heavily pretreated patients. The ability of Fludara FOR INJECTION to induce a significant rate of response in refractory patients suggests minimal cross-resistance with commonly used anti-CLL agents.
The median time to response in the MDAH and SWOG studies was 7 weeks (range of 1 to 68 weeks) and 21 weeks (range of 1 to 53 weeks), respectively. The median duration of disease control was 91 weeks (MDAH) and 65 weeks (SWOG). The median survival of all refractory CLL patients treated with Fludara FOR INJECTION was 43 weeks and 52 weeks in the MDAH and SWOG studies, respectively.
Rai stage improved to Stage II or better in 7 of 12 MDAH responders (58%) and in 5 of 7 SWOG responders (71%) who were Stage III or IV at baseline. In the combined studies, mean hemoglobin concentration improved from 9.0 g/dL at baseline to 11.8 g/dL at the time of response in a subgroup of anemic patients. Similarly, average platelet count improved from 63,500/mm3 to 103,300/mm3 at the time of response in a subgroup of patients who were thrombocytopenic at baseline.
Indications and Usage for Fludara
Fludara FOR INJECTION is indicated for the treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) who have not responded to or whose disease has progressed during treatment with at least one standard alkylating-agent containing regimen. The safety and effectiveness of Fludara FOR INJECTION in previously untreated or non-refractory patients with CLL have not been established.
Fludara FOR INJECTION is contraindicated in those patients who are hypersensitive to this drug or its components.
(See BOXED WARNINGS)
Dose Dependent Neurologic Toxicities
There are clear dose-dependent toxic effects seen with Fludara FOR INJECTION. Dose levels approximately 4 times greater (96 mg/m2/day for 5 to 7 days) than that recommended for CLL (25 mg/m2/day for 5 days) were associated with a syndrome characterized by delayed blindness, coma and death. Symptoms appeared from 21 to 60 days following the last dose. Thirteen of 36 patients (36%) who received Fludara FOR INJECTION at high doses (96 mg/m2/day for 5 to 7 days) developed this severe neurotoxicity. Similar severe central nervous system toxicity, including coma, seizures, agitation and confusion, has been reported in patients treated at doses in the range of the dose recommended for chronic lymphocytic leukemia.
In postmarketing experience neurotoxicity has been reported to occur either earlier or later than in clinical trials (range 7 to 225 days).
The effect of chronic administration of Fludara FOR INJECTION on the central nervous system is unknown; however, patients have received the recommended dose for up to 15 courses of therapy.
Bone Marrow Suppression
Severe bone marrow suppression, notably anemia, thrombocytopenia and neutropenia, has been reported in patients treated with Fludara FOR INJECTION. In a Phase I study in adult solid tumor patients, the median time to nadir counts was 13 days (range, 3-25 days) for granulocytes and 16 days (range, 2-32) for platelets. Most patients had hematologic 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 FOR INJECTION requires careful hematologic monitoring.
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.
Instances of life-threatening and sometimes fatal autoimmune phenomena such as hemolytic anemia, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evans syndrome, and acquired hemophilia have been reported to occur after one or more cycles of treatment with Fludara FOR INJECTION in patients with or without a previous history of autoimmune hemolytic anemia or a positive Coombs' test and who may or may not be in remission from their disease. Steroids may or may not be effective in controlling these hemolytic episodes. The majority of patients rechallenged with Fludara FOR INJECTION developed a recurrence in the hemolytic process. The mechanism(s) which predispose patients to the development of this complication has not been identified. Patients undergoing treatment with Fludara FOR INJECTION should be evaluated and closely monitored for hemolysis. Discontinuation of therapy with Fludara FOR INJECTION is recommended in case of hemolysis.
Transfusion Associated Graft-Versus-Host Disease
Transfusion-associated graft-versus-host disease has been observed after transfusion of non-irradiated blood in Fludara FOR INJECTION treated patients. Fatal outcome as a consequence of this disease has been reported. Therefore, to minimize 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 FOR INJECTION should receive irradiated blood only.
In a clinical investigation using Fludara FOR INJECTION in combination with pentostatin (deoxycoformycin) for the treatment of refractory chronic lymphocytic leukemia (CLL) in adults, there was an unacceptably high incidence of fatal pulmonary toxicity. Therefore, the use of Fludara FOR INJECTION in combination with pentostatin is not recommended.
Pregnancy Category D
Based on its mechanism of action, Fludarabine phosphate can cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies of Fludara FOR INJECTION in pregnant women. Fludarabine administered to rats and rabbits during organogenesis caused an increase in resorptions, skeletal and visceral malformations and decreased fetal body weights. If Fludara FOR INJECTION is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
Male Fertility and Reproductive Outcomes
Males with female sexual partners of childbearing potential should use contraception during and after cessation of Fludara FOR INJECTION therapy. Fludarabine may damage testicular tissue and spermatozoa. Possible sperm DNA damage raises concerns about loss of fertility and genetic abnormalities in fetuses. The duration of this effect is uncertain. [See PRECAUTIONS, Impairment of Fertility]
Fludara FOR INJECTION is a potent antineoplastic agent with potentially significant toxic side effects. Patients undergoing therapy should be closely observed for signs of hematologic and nonhematologic toxicity. Periodic assessment of peripheral blood counts is recommended to detect the development of anemia, neutropenia and thrombocytopenia.
In patients with impaired state of health, Fludara FOR INJECTION should be given with caution and after careful risk/benefit consideration. This applies especially for patients with severe impairment of bone marrow function (thrombocytopenia, anemia, and/or granulocytopenia), immunodeficiency or with a history of opportunistic infection. Prophylactic treatment should be considered in patients at increased risk of developing opportunistic infections.
Fludara FOR INJECTION may reduce the ability to drive or use machines, since fatigue, weakness, visual disturbances, confusion, agitation and seizures have been observed.
Tumor Cell Lysis
Tumor lysis syndrome has been associated with Fludara FOR INJECTION treatment. This syndrome has been reported in CLL patients with large tumor burden. Since Fludara FOR INJECTION 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.
Fludara FOR INJECTION must be administered cautiously in patients with renal impairment. The total body clearance of 2-fluoro-ara-A has been shown to be directly correlated with creatinine clearance. Patients with creatinine clearance 30-79 mL/min should have their Fludara FOR INJECTION dose reduced and be monitored closely for excessive toxicity. Fludara FOR INJECTION should not be administered to patients with creatinine clearance less than 30 mL/min. (See DOSAGE AND ADMINISTRATION section).
In patients aged 65 years or older, creatinine clearance should be measured before start of treatment.
During treatment, the patient’s hematologic profile (particularly neutrophils and platelets) should be monitored regularly to determine the degree of hematopoietic suppression.
The use of Fludara FOR INJECTION in combination with pentostatin is not recommended due to the risk of fatal pulmonary toxicity (see WARNINGS section).
No animal carcinogenicity studies with Fludara FOR INJECTION have been conducted.
Fludarabine phosphate was not mutagenic to bacteria (Ames test) or mammalian cells (HGRPT assay in Chinese hamster ovary cells) either in the presence or absence of metabolic activation. Fludarabine phosphate was clastogenic in vitro to Chinese hamster ovary cells (chromosome aberrations in the presence of metabolic activation) and induced sister chromatid exchanges both with and without metabolic activation. In addition, Fludarabine phosphate was clastogenic in vivo (mouse micronucleus assay) but was not mutagenic to germ cells (dominant lethal test in male mice).
Impairment of Fertility
Studies in mice, rats and dogs have demonstrated dose-related adverse effects on the male reproductive system. Observations consisted of a decrease in mean testicular weights in mice and rats with a trend toward decreased testicular weights in dogs and degeneration and necrosis of spermatogenic epithelium of the testes in mice, rats and dogs. The possible adverse effects on fertility in humans have not been adequately evaluated.
Pregnancy Category D (see WARNINGS section).
Based on its mechanism of action, Fludarabine phosphate can cause fetal harm when administered to a pregnant woman. There are not adequate and well-controlled studies of Fludarabine phosphate in pregnant women. Fludarabine phosphate was embryolethal and teratogenic in rats and rabbits. If Fludara FOR INJECTION is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
In rats, repeated intravenous doses of Fludarabine phosphate at 2.4 times and 7.2 times the recommended human IV dose (25 mg/m2) administered during organogenesis caused an increase in resorptions, skeletal and visceral malformations (cleft palate, exencephaly, and fetal vertebrae deformities) and decreased fetal body weights. Maternal toxicity was not apparent at 2.4 times the human IV dose, and was limited to slight body weight decreases at 7.2 times the human IV dose. In rabbits, repeated intravenous doses of Fludarabine phosphate at 3.8 times the human IV dose administered during organogenesis increased embryo and fetal lethality as indicated by increased resorptions and a decrease in live fetuses. A significant increase in malformations including cleft palate, hydrocephaly, adactyly, brachydactyly, fusions of the digits, diaphragmatic hernia, heart/great vessel defects, and vertebrae/rib anomalies were seen in all dose levels (≥ 0.5 times the human IV dose).
It is not known whether Fludarabine phosphate is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions including tumorigenicity in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Data submitted to the FDA was insufficient to establish efficacy in any childhood malignancy. Fludara FOR INJECTION was evaluated in 62 pediatric patients (median age 10, range 1-21) with refractory acute leukemia (45 patients) or solid tumors (17 patients). The Fludara FOR INJECTION regimen tested for pediatric acute lymphocytic leukemia (ALL) patients was a loading bolus of 10.5 mg/m2/day followed by a continuous infusion of 30.5 mg/m2/day for 5 days. In 12 pediatric patients with solid tumors, dose-limiting myelosuppression was observed with a loading dose of 8 mg/m2/day followed by a continuous infusion of 23.5 mg/m2/day for 5 days. The maximum tolerated dose was a loading dose of 7 mg/m2/day followed by a continuous infusion of 20 mg/m2/day for 5 days. Treatment toxicity included bone marrow suppression. Platelet counts appeared to be more sensitive to the effects of Fludara FOR INJECTION than hemoglobin and white blood cell counts. Other adverse events included fever, chills, asthenia, rash, nausea, vomiting, diarrhea, and infection. There were no reported occurrences of peripheral neuropathy or pulmonary hypersensitivity reaction.
During and after treatment with Fludara FOR INJECTION, vaccination with live vaccines should be avoided.
Richter’s syndrome has been reported in CLL patients.
Very common adverse events include myelosuppression (neutropenia, thrombocytopenia and anemia), fever and chills, fatigue, weakness, infection, pneumonia, cough, nausea, vomiting, and diarrhea. Other commonly reported events include malaise, mucositis and anorexia. Serious opportunistic infections (such as latent viral reactivation, herpes zoster virus, Epstein-Barr virus, and progressive multifocal leukoencephalopathy) have occurred in CLL patients treated with Fludara FOR INJECTION. Adverse events and those reactions which are more clearly related to the drug are arranged below according to body system.
Hematologic events (neutropenia, thrombocytopenia, and/or anemia) were reported in the majority of CLL patients treated with Fludara FOR INJECTION. During Fludara FOR INJECTION treatment of 133 patients with CLL, the absolute neutrophil count decreased to less than 500/mm3 in 59% of patients, hemoglobin decreased from pretreatment values by at least 2 grams percent in 60%, and platelet count decreased from pretreatment values by at least 50% in 55%. Myelosuppression may be severe, cumulative, and may affect multiple cell lines. Bone marrow fibrosis occurred in one CLL patient treated with Fludara FOR INJECTION.
Several instances of trilineage bone marrow hypoplasia or aplasia resulting in pancytopenia, sometimes resulting in death, have been reported in post-marketing surveillance. 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.
Life-threatening and sometimes fatal autoimmune phenomena such as hemolytic anemia, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evans syndrome, and acquired hemophilia have been reported to occur in patients receiving Fludara FOR INJECTION (see WARNINGS section). The majority of patients rechallenged with Fludara FOR INJECTION developed a recurrence in the hemolytic process.
In post-marketing experience, cases of myelodysplastic syndrome and acute myeloid leukemia, mainly associated with prior, concomitant or subsequent treatment with alkylating agents, topoisomerase inhibitors, or irradiation have been reported.
Serious and sometimes fatal infections, including opportunistic infections and reactivations of latent viral infections such as VZV (herpes zoster), Epstein-Barr virus and JC virus (progressive multifocal leukoencephalopathy) have been reported in patients treated with Fludara FOR INJECTION.
Rare cases of Epstein-Barr virus (EBV) associated lymphoproliferative disorders have been reported in patients treated with Fludara FOR INJECTION.
In post-marketing experience, cases of progressive multifocal leukoencephalopathy have been reported. Most cases had a fatal outcome. Many of these cases were confounded by prior and/or concurrent chemotherapy. The time to onset has ranged from a few weeks to approximately one year after initiating treatment.
Of the 133 adult CLL patients in the two trials, there were 29 fatalities during study, approximately 50% of which were due to infection.
Tumor lysis syndrome has been reported in CLL patients treated with Fludara FOR INJECTION. This complication may include hyperuricemia, hyperphosphatemia, hypocalcemia, metabolic acidosis, hyperkalemia, hematuria, urate crystalluria, and renal failure. The onset of this syndrome may be heralded by flank pain and hematuria.
(see WARNINGS section)
Objective weakness, agitation, confusion, seizures, visual disturbances, optic neuritis, optic neuropathy, blindness and coma have occurred in CLL patients treated with Fludara FOR INJECTION at the recommended dose. Peripheral neuropathy has been observed in patients treated with Fludara FOR INJECTION and one case of wrist-drop was reported. There have been additional reports of cerebral hemorrhage though the frequency is not known.
Pneumonia, a frequent manifestation of infection in CLL patients, occurred in 16% and 22% of those treated with Fludara FOR INJECTION in the MDAH and SWOG studies, respectively. Pulmonary hypersensitivity reactions to Fludara FOR INJECTION characterized by dyspnea, cough and interstitial pulmonary infiltrate have been observed.
In post-marketing experience, cases of severe pulmonary toxicity have been observed with Fludara FOR INJECTION use which resulted in ARDS, respiratory distress, pulmonary hemorrhage, pulmonary fibrosis, pneumonitis and respiratory failure. After an infectious origin has been excluded, some patients experienced symptom improvement with corticosteroids.
Gastrointestinal disturbances such as nausea and vomiting, anorexia, diarrhea, stomatitis and gastrointestinal bleeding and hemorrhage have been reported in patients treated with Fludara FOR INJECTION. Elevations of pancreatic enzyme levels have also been reported.
Edema has been frequently reported. One patient developed a pericardial effusion possibly related to treatment with Fludara FOR INJECTION. There have been additional reports of heart failure and arrhythmia though the frequency is rare. No other severe cardiovascular events were considered to be drug related.
Rare cases of hemorrhagic cystitis have been reported in patients treated with Fludara FOR INJECTION.
Skin toxicity, consisting primarily of skin rashes, has been reported in patients treated with Fludara FOR INJECTION. Erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis and pemphigus have been reported, with fatal outcomes in some cases.
Worsening or flare-up of pre-existing skin cancer lesions, as well as new onset of skin cancer, has been reported in patients during or after treatment with Fludara FOR INJECTION.
Elevations of hepatic enzyme levels have been reported.
Data in the following table are derived from the 133 patients with CLL who received Fludara FOR INJECTION in the MDAH and SWOG studies.

More than 3000 adult patients received Fludara FOR INJECTION in studies of other leukemias, lymphomas, and other solid tumors. The spectrum of adverse effects reported in these studies was consistent with the data presented above.
High doses of Fludara FOR INJECTION (see WARNINGS section) have been associated with an irreversible central nervous system toxicity characterized by delayed blindness, coma and death. High doses are also associated with severe thrombocytopenia and neutropenia due to bone marrow suppression. There is no known specific antidote for Fludara FOR INJECTION overdosage. Treatment consists of drug discontinuation and supportive therapy.
Fludara Dosage and Administration
The recommended adult dose of Fludara FOR INJECTION is 25 mg/m2 administered intravenously over a period of approximately 30 minutes daily for five consecutive days. Each 5 day course of treatment should commence every 28 days. Dosage may be decreased or delayed based on evidence of hematologic or nonhematologic toxicity. Physicians should consider delaying or discontinuing the drug if neurotoxicity occurs.
A number of clinical settings may predispose to increased toxicity from Fludara FOR INJECTION. These include advanced age, renal impairment, and bone marrow impairment. Such patients should be monitored closely for excessive toxicity and the dose modified accordingly.
The optimal duration of treatment has not been clearly established. It is recommended that three additional cycles of Fludara FOR INJECTION be administered following the achievement of a maximal response and then the drug should be discontinued.
Adjustments to the starting dose are recommended to provide appropriate drug exposure in patients with creatinine clearance 30-79 mL/min, as estimated by the Cockroft-Gault equations. These adjustments are based on a pharmacokinetic study in patients with renal impairment. Fludara FOR INJECTION should not be administered to patients with creatinine clearance less than 30 mL/min.
