Overview
Fludarabine (oral) is a anti neoplastic that is FDA approved for the treatment of B-cell chronic lymphocytic leukemia (CLL). There is a Black Box Warning for this drug as shown here. Common adverse reactions include myelosuppression (neutropenia, thrombocytopenia and anemia), fever and chills, infection, and nausea and vomiting. Other commonly reported events include malaise, fatigue, anorexia, and weakness.
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
Indication
- Fludarabine phosphate is indicated as a single agent for the treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) whose disease has not responded to or has progressed during or after treatment with at least one standard alkylating-agent containing regimen. Studies demonstrating clinical benefit such as prolongation of survival or relief of symptoms have not been performed. Studies providing a direct comparison of the clinical efficacy and safety of orally administered fludarabine phosphate relative to intravenously administered fludarabine phosphate have not been performed.
Dosage
Chronic Lymphocytic Leukemia (CLL)
- The oral dose is different than the intravenous dose.
- The recommended adult dose of fludarabine phosphate is 40 mg/m2 administered by mouth 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. Fludarabine phosphate film-coated tablets can be taken either on an empty stomach or with food. The tablets have to be swallowed whole with water; they should not be chewed or broken.
- The following table provides guidance for determining the number of tablets of fludarabine phosphate to be administered based on body surface area (BSA):

- A number of clinical settings may predispose to increased toxicity from fludarabine phosphate. These include advanced age, renal insufficiency, 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 fludarabine phosphate be administered following the achievement of a maximal response and then the drug should be discontinued.

CNS TOXICITY, HEMOLYTIC ANEMIA, AND PULMONARY TOXICITY
|
Neurotoxicity
- Dose-dependent neurotoxicity has been observed with fludarabine phosphate. Dose levels approximately 4 times greater (96 mg/m2/day for 5 days to 7 days) than the recommended intravenous dose (25 mg/m2/day for 5 days) were associated with a syndrome characterized by delayed blindness, coma and death. Symptoms appeared from 21 days to 60 days following the last dose. Thirteen of 36 patients (36.1%) who received fludarabine phosphate intravenously at high doses (≥ 96 mg/m2/day for 5 days to 7 days per course) developed severe neurotoxicity, while only one of 443 patients (0.2%) who received the drug intravenously at low doses (≤ 40 mg/m2/day for 5 days per course) developed toxicity. In the pivotal clinical study conducted with fludarabine phosphate film-coated tablets administered at 40 mg/m2, severe impairment of consciousness was reported in one patient. The effect of chronic administration of fludarabine phosphate on the central nervous system is unknown; however, patients have received the recommended dose for up to 15 courses of therapy. Physicians should consider delaying or discontinuing the drug if neurotoxicity occurs.
Bone Marrow Suppression
- Severe bone marrow suppression, notably anemia, thrombocytopenia and neutropenia, has been reported in patients treated with fludarabine phosphate. In a study in adult solid tumor patients, the median time to nadir counts was 13 days (range, 3 days to 25 days) for granulocytes and 16 days (range, 2 days to 32 days) 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 fludarabine phosphate 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. One case of pancytopenia was reported in the pivotal clinical study conducted with oral fludarabine phosphate tablets.
- Instances of life-threatening and sometimes fatal autoimmune hemolytic anemia have been reported to occur after one or more cycles of treatment with fludarabine phosphate 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 fludarabine phosphate 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 fludarabine phosphate should be evaluated and closely monitored for hemolysis.
Pulmonary Toxicity
- A high incidence of fatal pulmonary toxicity was observed in a clinical investigation using fludarabine phosphate in combination with pentostatin (deoxycoformycin) for the treatment of refractory chronic lymphocytic leukemia (CLL) in adults. Therefore, the use of fludarabine phosphate in combination with pentostatin is not recommended.
Infections
- Of 133 adult patients with CLL who received intravenous fludarabine phosphate in two clinical trials, there were 29 fatalities during study. Approximately 50% of the fatalities were due to infection and 25% due to progressive disease. Of 183 adult patients with CLL that received oral fludarabine phosphate in two clinical trials, there were 13 deaths. Approximately 50% of the deaths were due to progressive disease, while two patient deaths (15%) were attributed to infection. Monitor for signs and symptoms of infection.
Tumor Lysis Syndrome
- Tumor lysis syndrome associated with fludarabine phosphate treatment has been reported in patients with CLL with large tumor burdens. Since fludarabine phosphate 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.
Use of Transfusions
- Transfusion-associated graft-versus-host disease has been observed rarely after transfusion of non-irradiated blood in fludarabine phosphate treated patients. Consideration should, therefore, be given to the use of irradiated blood products in those patients requiring transfusions while undergoing treatment with fludarabine phosphate.
Renal Impairment
- Fludarabine phosphate must be administered cautiously in patients with renal impairment. Following dosing of the intravenous product, the total body clearance of 2-fluoro-ara-A has been shown to be directly correlated with creatinine clearance. Patients with mild to moderate impairment of renal function (creatinine clearance 30 to 70 mL/min/1.73 m2) should have their oral fludarabine phosphate dose reduced by 20% and be monitored closely. Patients with severe impairment of renal function (creatinine clearance < 30 mL/min/1.73 m2) should have their oral fludarabine phosphate dose reduced by 50% and be monitored closely.
Monitoring
- Hematologic and Nonhematologic Toxicity
- Fludarabine phosphate is an 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.
- Hematopoietic Suppression
- During treatment, the patient’s hematologic profile (particularly neutrophils and platelets) should be monitored regularly to determine the degree of hematopoietic suppression.
- Infections
- Patients treated with fludarabine phosphate appear to be at an increased risk of infection. Monitor for signs and symptoms of infection.
- Pregnancy
- Based on its mechanism of action, fludarabine phosphate can cause fetal harm when administered to a pregnant woman. Fludarabine phosphate administered to rats and rabbits during organogenesis caused an increase in resorptions, skeletal and visceral malformation, and decreased fetal body weights. If fludarabine phosphate 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. Women of childbearing potential and fertile males must take contraceptive measures during and at least for 6 months after the cessation of therapy.
Adverse Reactions
Clinical Trials Experience
Clinical Trials Experience
- Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
- The data described below reflect exposure to fludarabine phosphate tablets in 159 patients exposed to the drug. Fludarabine phosphate tablets were studied primarily in Study 1 in 78 patients with CLL who received prior therapy and in Study 2 in 81 patients with CLL who had not received prior therapy.
- Based on experience with the intravenous and oral use of fludarabine phosphate, the most common adverse reactions include myelosuppression (neutropenia, thrombocytopenia and anemia), fever and chills, infection, and nausea and vomiting. Other commonly reported events include malaise, fatigue, anorexia, and weakness. Serious opportunistic infections have occurred in patients with CLL treated with fludarabine phosphate. The most frequently reported adverse reactions and those reactions which are more clearly related to the drug, as reported in clinical studies conducted with intravenous and oral fludarabine phosphate, are arranged below according to body system.
- Hematopoietic Systems
- Hematologic events (neutropenia, thrombocytopenia, and/or anemia) were reported in the majority of patients with CLL treated with fludarabine phosphate. During intravenous fludarabine phosphate 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%. Among 78 patients with B-CLL who were treated with oral fludarabine phosphate, the absolute neutrophil count decreased to less than 500/mm3 in 37% of patients, hemoglobin decreased from pretreatment values by at least 2 grams percent in 14%, and platelet count decreased from pretreatment values by at least 50% in 17% of patients. Myelosuppression may be severe, cumulative, and may affect multiple cell lines. Bone marrow fibrosis occurred in one CLL patient treated with fludarabine phosphate intravenously. In the pivotal oral fludarabine phosphate study (Study 1), there was one report of a non-fatal case of pancytopenia. Similarly, there was one case of non-fatal pancytopenia reported among the 133 patients with CLL treated with intravenous fludarabine phosphate.
- Life-threatening and sometimes fatal autoimmune hemolytic anemias have been reported to occur in patients receiving fludarabine phosphate. The majority of patients rechallenged with fludarabine phosphate developed a recurrence in the hemolytic process.
- Metabolic
- Tumor lysis syndrome has been reported in patients with CLL treated with fludarabine phosphate 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.
- Nervous System
- Objective weakness, agitation, confusion, visual disturbances, and coma have occurred in patients with CLL treated with fludarabine phosphate at the recommended dose. Peripheral neuropathy and one case of wrist-drop have been observed with intravenous administration of fludarabine phosphate. In Study 1 for oral fludarabine phosphate, there was one report of severe impairment of consciousness that presented concurrent with hemolytic anemia. This patient had enrolled in the study with pre-existing peripheral neurotoxicity.
- Pulmonary System
- Pneumonia, a frequent manifestation of infection in patients with CLL, was observed in two clinical trials conducted with intravenous fludarabine phosphate (16% and 22%) and in two clinical trials with oral fludarabine phosphate (8% and 3%). Pulmonary hypersensitivity reactions to fludarabine phosphate characterized by dyspnea, cough and interstitial pulmonary infiltrate have been observed. In Study 1 conducted with oral fludarabine phosphate, severe pulmonary toxicity was reported in 5 of 78 patients, often in conjunction with respiratory or pulmonary infections and hence not regarded as isolated drug related pulmonary toxicity.
- Gastrointestinal System
- Gastrointestinal disturbances such as nausea and vomiting, anorexia, diarrhea, stomatitis and gastrointestinal bleeding have been reported in patients treated with fludarabine phosphate. Nausea and vomiting occurred in up to 38% of patients following treatment with oral fludarabine phosphate in the clinical trials.
- Cardiovascular
- Edema has been frequently reported. One patient developed a pericardial effusion possibly related to treatment with fludarabine phosphate. No other severe cardiovascular events were considered to be drug related.
- Genitourinary System
- Hemorrhagic cystitis has been reported in patients treated intravenously with fludarabine phosphate.
- Skin toxicity, consisting primarily of skin rashes, has been reported in patients treated with oral and intravenous fludarabine phosphate.

Postmarketing Experience
- The following adverse reactions have been identified during post approval use of oral fludarabine phosphate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possibly to reliably estimate their frequency or establish a causal relationship to drug exposure.
- Hematopoietic Systems
- 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.
- Nervous System
- 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 median time to onset was approximately one year.
- Pulmonary System
- In post-marketing experience, cases of severe pulmonary toxicity have been observed with fludarabine phosphate use which resulted in acute respiratory distress syndrome, respiratory distress, pulmonary hemorrhage, pulmonary fibrosis, and respiratory failure. After exclusion of an infectious origin, some patients experienced symptom improvement with corticosteroids.
Drug Interactions
- The use of fludarabine phosphate in combination with pentostatin is not recommended due to the risk of severe pulmonary toxicity.
Use in Specific Populations
Pregnancy
- 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 fludarabine phosphate in pregnant women. Fludarabine phosphate was embryolethal and teratogenic in both rats and rabbits. If fludarabine phosphate 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. Women of childbearing potential and fertile males must take contraceptive measures during and at least for 6 months after the cessation of therapy.
- In rats, repeated intravenous doses of fludarabine phosphate at 1.5 times and 4.5 times the recommended human oral dose (40 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 1.5 times the human oral dose, and was limited to slight body weight decreases at 4.5 times the human oral dose. In rabbits, repeated intravenous doses of fludarabine phosphate at 2.4 times the human oral 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 (≥ 0.3 times the human oral dose).
- Australian Drug Evaluation Committee (ADEC) Pregnancy Category
There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Fludarabine (oral) in women who are pregnant.
Labor and Delivery
There is no FDA guidance on use of Fludarabine (oral) during labor and delivery.
Nursing Mothers
- 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 tumorgenicity 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.
Pediatric Use
There is no FDA guidance on the use of Fludarabine (oral) with respect to pediatric patients.
Geriatic Use
- Of 78 previously treated patients with B-CLL treated with oral fludarabine phosphate 50% were ≥ age 65 and 3% were ≥ age 75. The response rate was generally lower among patients age 65 and older. Among previously treated patients (Study 1) age 65 and older, the overall objective response, according to standardized response criteria developed by the National Cancer Institute CLL Working Group (NCI criteria), was 41%. The safety profile among younger and older patients on study was similar. Other reported clinical experience has not identified differences in responses or safety between older and younger patients.
Gender
There is no FDA guidance on the use of Fludarabine (oral) with respect to specific gender populations.
Race
There is no FDA guidance on the use of Fludarabine (oral) with respect to specific racial populations.
Renal Impairment
- In patients receiving intravenous fludarabine phosphate, the total body clearance of the metabolite 2-fluoro-ara-adenine (2F-ara-A) correlated with the creatinine clearance, indicating the importance of the renal excretion pathway for the elimination of the drug. Renal clearance represented approximately 40% of the total body clearance. Patients with mild to moderate renal impairment (30 to 70 mL/min/1.73 m2) receiving 20% reduced fludarabine phosphate dose had a similar exposure compared to patients with normal renal function receiving the recommended dose (AUC; 21 nM•h/mL versus 20 nM•h/mL). Two patients with severe renal impairment (< 30 mL/min/1.73 m2) receiving 40% reduced fludarabine phosphate dose had a 40% increase in exposure compared to patients with normal renal function receiving the recommended dose. The mean total body clearance was 172 mL/min for patients with normal renal function, 124 mL/min for patients with mild to moderately impaired renal function, and 71 mL/min for the two patients with severe renal impairment.
Hepatic Impairment
There is no FDA guidance on the use of Fludarabine (oral) in patients with hepatic impairment.

Overdosage
- High doses of fludarabine phosphate 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 fludarabine phosphate overdosage. Treatment consists of drug discontinuation and supportive therapy. In Study 2, two patients ingested an overdose of 20% to 33% of oral fludarabine phosphate. No serious side effects were reported.
Pharmacology
Mechanism of Action
- 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.
Structure
- *Fludarabine Phosphate Injection contains fludarabine phosphate, a nucleotide metabolic inhibitor. Fludarabine phosphate is 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 mL contains 25 mg of the active ingredient fludarabine phosphate, 1.78 mg disodium phosphate dihydrate, water for injection, qs; and sodium hydroxide to adjust pH to 7.5. The pH range for the final product is 7.3 to 7.7. Fludarabine Phosphate Injection is a sterile solution intended for intravenous administration.
- The chemical name for fludarabine phosphate is 9H-Purin-6-amine, 2-fluoro-9-(5-0-phosphono-β-D-arabinofuranosyl)(2-fluoro-ara-AMP).
The molecular formula of fludarabine phosphate is C10H13FN5O7P (MW 365.2) and the structure is provided in Figure 1

Clinical Studies
- Study 1, a single-arm, open-label study of fludarabine phosphate film-coated tablets was conducted in 78 adult patients with CLL refractory to at least one prior standard alkylating-agent containing regimen. In this multicenter study patients were treated with oral fludarabine phosphate at a dose of 40 mg/m2 daily for 5 days every 28 days. The patient population median age was 64.5 years and consisted of 72% males and 28% females. Ninety-nine percent of the patients were Caucasian. The Rai stage for patients entering the study was: Stage 0 (3.9%), Stage I (20.5%), Stage II (32.1%), Stage III (11.5%), and Stage IV (32.1%). The mean number of treatment cycles was 5.1 with a mean daily dose of fludarabine phosphate of 38 mg/m2. The overall objective response, according to standardized response criteria developed by the National Cancer Institute CLL Working Group (NCI criteria), was 51 %, including 18% complete responses and 33% partial responses. The overall response rate, according to standardized criteria developed by the International Workshop on CLL (IWCLL criteria), was 46%, including 21% complete responses and 26% partial responses. Data on duration of response was not collected.
- In Study 2, a supportive single-arm, open-label study, fludarabine phosphate tablets were administered to 81 previously untreated patients with B-CLL. In this multicenter study each patient was treated with oral fludarabine phosphate at a dose of 40 mg/m2 daily for 5 days every 28 days. The patient population median age was 64.0 years and consisted of 63% males and 37% females. Ninety-nine percent of the patients were Caucasian. The Rai stage for patients entering the study was: Stage 0 (3.7%), Stage I (37.0%), Stage II (37.0%), Stage III (9.9%), and Stage IV (12.3%). The mean number of treatment cycles was 5.9 with a mean daily dose per patient of 71 mg to 74 mg. The overall responses rate, according to NCI criteria, was 80%, including 12% complete responses and 68% partial responses. The overall response rate, according to IWCLL criteria, was 72%, including 37% complete responses and 35% partial responses. The median duration of response was 22.9 months.
- Study 3 was a supportive randomized controlled open label study in patients with previously untreated B-CLL that included fludarabine phosphate monotherapy and fludarabine phosphate combination therapy arms. In this study 107 evaluable patients received fludarabine phosphate 40mg/m2 orally daily for 5 days every 28 days. The overall response rate according to modified NCI criteria was 74% and the CR plus nodular PR rate was 41%.
