BOXED WARNING
(What is this?)
WARNING: CAPECITABINE TABLETS-WARFARIN INTERACTION
Capecitabine Tablets-Warfarin Interaction: Patients receiving concomitant capecitabine and oral coumarin-derivative anticoagulant therapy should have their anticoagulant response (INR or prothrombin time) monitored frequently in order to adjust the anticoagulant dose accordingly. A clinically important capecitabine tablets-warfarin drug interaction was demonstrated in a clinical pharmacology trial [see Warnings and Precautions (5.2) and Drug Interactions (7.1)]. Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking capecitabine tablets concomitantly with coumarin-derivative anticoagulants such as warfarin and phenprocoumon. Postmarketing reports have shown clinically significant increases in prothrombin time (PT) and INR in patients who were stabilized on anticoagulants at the time capecitabine tablets were introduced. These events occurred within several days and up to several months after initiating capecitabine tablets therapy and, in a few cases, within 1 month after stopping capecitabine tablets. These events occurred in patients with and without liver metastases. Age greater than 60 and a diagnosis of cancer independently predispose patients to an increased risk of coagulopathy.
-
1 INDICATIONS AND USAGE
1.1 Colorectal Cancer
- Capecitabine tablets are indicated as a single agent for adjuvant treatment in patients with Dukes’ C colon cancer who have undergone complete resection of the primary tumor when treatment with fluoropyrimidine therapy alone is preferred. Capecitabine tablets were non-inferior to 5-fluorouracil and leucovorin (5-FU/LV) for disease-free survival (DFS). Physicians should consider results of combination chemotherapy trials, which have shown improvement in DFS and OS, when prescribing single-agent capecitabine tablets in the adjuvant treatment of Dukes’ C colon cancer.
- Capecitabine tablets are indicated as first-line treatment of patients with metastatic colorectal carcinoma when treatment with fluoropyrimidine therapy alone is preferred. Combination chemotherapy has shown a survival benefit compared to 5-FU/LV alone. A survival benefit over 5-FU/LV has not been demonstrated with capecitabine tablets monotherapy. Use of capecitabine tablets instead of 5-FU/LV in combinations has not been adequately studied to assure safety or preservation of the survival advantage.
1.2 Breast Cancer
- Capecitabine tablets in combination with docetaxel are indicated for the treatment of patients with metastatic breast cancer after failure of prior anthracycline-containing chemotherapy.
- Capecitabine tablets monotherapy is also indicated for the treatment of patients with metastatic breast cancer resistant to both paclitaxel and an anthracycline-containing chemotherapy regimen or resistant to paclitaxel and for whom further anthracycline therapy is not indicated (e.g., patients who have received cumulative doses of 400 mg/m2 of doxorubicin or doxorubicin equivalents). Resistance is defined as progressive disease while on treatment, with or without an initial response, or relapse within 6 months of completing treatment with an anthracycline-containing adjuvant regimen.
-
2 DOSAGE AND ADMINISTRATION
2.1 Important Administration Instructions
Capecitabine tablets should be swallowed whole with water within 30 minutes after a meal. Capecitabine tablets are a cytotoxic drug. Follow applicable special handling and disposal procedures.1 If capecitabine tablets must be cut or crushed, this should be done by a professional trained in safe handling of cytotoxic drugs using appropriate equipment and safety procedures. Capecitabine tablets dose is calculated according to body surface area.
2.2 Standard Starting Dose
Monotherapy (Metastatic Colorectal Cancer, Adjuvant Colorectal Cancer, Metastatic Breast Cancer)
The recommended dose of capecitabine tablets is 1250 mg/m2 administered orally twice daily (morning and evening; equivalent to 2500 mg/m2 total daily dose) for 2 weeks followed by a 1-week rest period given as 3-week cycles (see Table 1).
Adjuvant treatment in patients with Dukes’ C colon cancer is recommended for a total of 6 months [i.e., capecitabine tablets 1250 mg/m2 orally twice daily for 2 weeks followed by a 1-week rest period, given as 3-week cycles for a total of 8 cycles (24 weeks)].

In Combination With Docetaxel (Metastatic Breast Cancer)
In combination with docetaxel, the recommended dose of capecitabine tablets is 1250 mg/m2 twice daily for 2 weeks followed by a 1-week rest period, combined with docetaxel at 75 mg/m2 as a 1-hour intravenous infusion every 3 weeks. Pre-medication, according to the docetaxel labeling, should be started prior to docetaxel administration for patients receiving the capecitabine tablets plus docetaxel combination. Table 1 displays the total daily dose of capecitabine tablets by body surface area and the number of tablets to be taken at each dose.
2.3 Dose Management Guidelines
General
Capecitabine tablets dosage may need to be individualized to optimize patient management. Patients should be carefully monitored for toxicity and doses of capecitabine tablets should be modified as necessary to accommodate individual patient tolerance to treatment [see Clinical Studies (14)]. Toxicity due to capecitabine tablets administration may be managed by symptomatic treatment, dose interruptions and adjustment of capecitabine tablets dose. Once the dose has been reduced, it should not be increased at a later time. Doses of capecitabine tablets omitted for toxicity are not replaced or restored; instead the patient should resume the planned treatment cycles.
The dose of phenytoin and the dose of coumarin-derivative anticoagulants may need to be reduced when either drug is administered concomitantly with capecitabine tablets [see Drug Interactions (7.1)].
Monotherapy (Metastatic Colorectal Cancer, Adjuvant Colorectal Cancer, Metastatic Breast Cancer)
Capecitabine tablets dose modification scheme as described below (see Table 2) is recommended for the management of adverse reactions.
Table 2. Recommended Dose Modifications of Capecitabine Tablets - * National Cancer Institute of Canada Common Toxicity Criteria were used except for the hand-and-foot syndrome [see Warnings and Precautions (5)].

2.4 Adjustment of Starting Dose in Special Populations
Renal Impairment
No adjustment to the starting dose of capecitabine tablets is recommended in patients with mild renal impairment (creatinine clearance = 51 to 80 mL/min [Cockroft and Gault, as shown below]). In patients with moderate renal impairment (baseline creatinine clearance = 30 to 50 mL/min), a dose reduction to 75% of the capecitabine tablets starting dose when used as monotherapy or in combination with docetaxel (from 1250 mg/m2 to 950 mg/m2 twice daily) is recommended [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)]. Subsequent dose adjustment is recommended as outlined in Table 2 and Table 3 (depending on the regimen) if a patient develops a grade 2 to 4 adverse event [see Warnings and Precautions (5.5)]. The starting dose adjustment recommendations for patients with moderate renal impairment apply to both capecitabine tablets monotherapy and capecitabine tablets in combination use with docetaxel.
Cockroft and Gault Equation:
Creatinine clearance for males =
(140 - age [yrs]) (body wt [kg])
(72) (serum creatinine [mg/dL])
Creatinine clearance for females = 0.85 x male value

-
4 CONTRAINDICATIONS
4.1 Severe Renal Impairment
Capecitabine tablets are contraindicated in patients with severe renal impairment (creatinine clearance below 30 mL/min [Cockroft and Gault]) [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].
-
5 WARNINGS AND PRECAUTIONS
5.1 Coagulopathy
Patients receiving concomitant capecitabine and oral coumarin-derivative anticoagulant therapy should have their anticoagulant response (INR or prothrombin time) monitored closely with great frequency and the anticoagulant dose should be adjusted accordingly [see Boxed Warning and Drug Interactions (7.1)].
5.2 Diarrhea
Capecitabine tablets can induce diarrhea, sometimes severe. Patients with severe diarrhea should be carefully monitored and given fluid and electrolyte replacement if they become dehydrated. In 875 patients with either metastatic breast or colorectal cancer who received capecitabine tablets monotherapy, the median time to first occurrence of grade 2 to 4 diarrhea was 34 days (range from 1 to 369 days). The median duration of grade 3 to 4 diarrhea was 5 days. National Cancer Institute of Canada (NCIC) grade 2 diarrhea is defined as an increase of 4 to 6 stools/day or nocturnal stools, grade 3 diarrhea as an increase of 7 to 9 stools/day or incontinence and malabsorption, and grade 4 diarrhea as an increase of ≥ 10 stools/day or grossly bloody diarrhea or the need for parenteral support. If grade 2, 3 or 4 diarrhea occurs, administration of capecitabine tablets should be immediately interrupted until the diarrhea resolves or decreases in intensity to grade 1 [see Dosage and Administration (2.3)]. Standard antidiarrheal treatments (e.g., loperamide) are recommended.
Necrotizing enterocolitis (typhlitis) has been reported.
5.3 Cardiotoxicity
The cardiotoxicity observed with capecitabine tablets includes myocardial infarction/ischemia, angina, dysrhythmias, cardiac arrest, cardiac failure, sudden death, electrocardiographic changes, and cardiomyopathy. These adverse reactions may be more common in patients with a prior history of coronary artery disease.
5.4 Dihydropyrimidine Dehydrogenase Deficiency
Based on postmarketing reports, patients with certain homozygous or certain compound heterozygous mutations in the DPD gene that result in complete or near complete absence of DPD activity are at increased risk for acute early-onset of toxicity and severe, life-threatening, or fatal adverse reactions caused by capecitabine tablets (e.g., mucositis, diarrhea, neutropenia, and neurotoxicity). Patients with partial DPD activity may also have increased risk of severe, life-threatening, or fatal adverse reactions caused by capecitabine tablets.
Withhold or permanently discontinue capecitabine tablets based on clinical assessment of the onset, duration and severity of the observed toxicities in patients with evidence of acute early-onset or unusually severe toxicity, which may indicate near complete or total absence of DPD activity. No capecitabine tablets dose has been proven safe for patients with complete absence of DPD activity. There is insufficient data to recommend a specific dose in patients with partial DPD activity as measured by any specific test.
5.5 Dehydration and Renal Failure
Dehydration has been observed and may cause acute renal failure which can be fatal. Patients with pre-existing compromised renal function or who are receiving concomitant capecitabine tablets with known nephrotoxic agents are at higher risk. Patients with anorexia, asthenia, nausea, vomiting or diarrhea may rapidly become dehydrated. Monitor patients when capecitabine tablets are administered to prevent and correct dehydration at the onset. If grade 2 (or higher) dehydration occurs, capecitabine tablets treatment should be immediately interrupted and the dehydration corrected. Treatment should not be restarted until the patient is rehydrated and any precipitating causes have been corrected or controlled. Dose modifications should be applied for the precipitating adverse event as necessary [see Dosage and Administration (2.3)].
Patients with moderate renal impairment at baseline require dose reduction [see Dosage and Administration (2.4)]. Patients with mild and moderate renal impairment at baseline should be carefully monitored for adverse reactions. Prompt interruption of therapy with subsequent dose adjustments is recommended if a patient develops a grade 2 to 4 adverse event as outlined in Table 2 [see Dosage and Administration (2.3), Use in Specific Populations (8.7), and Clinical Pharmacology (12.3)].
5.6 Embryo-Fetal Toxicity
Based on findings from animal reproduction studies and its mechanism of action, capecitabine tablets may cause fetal harm when given to a pregnant woman [see Clinical Pharmacology (12.1)]. Limited available data are not sufficient to inform use of capecitabine tablets in pregnant women. In animal reproduction studies, administration of capecitabine to pregnant animals during the period of organogenesis caused embryolethality and teratogenicity in mice and embryolethality in monkeys at 0.2 and 0.6 times the exposure (AUC) in patients receiving the recommended dose respectively [see Use in Specific Populations (8.1)]. Apprise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of capecitabine tablets [see Use in Specific Populations (8.3)].
5.7 Mucocutaneous and Dermatologic Toxicity
Severe mucocutaneous reactions, some with fatal outcome, such as Stevens-Johnson syndrome and Toxic Epidermal Necrolysis (TEN) can occur in patients treated with capecitabine tablets [see Adverse Reactions (6.4)]. Capecitabine tablets should be permanently discontinued in patients who experience a severe mucocutaneous reaction possibly attributable to capecitabine tablets treatment.
Hand-and-foot syndrome (palmar-plantar erythrodysesthesia or chemotherapy-induced acral erythema) is a cutaneous toxicity. Median time to onset was 79 days (range from 11 to 360 days) with a severity range of grades 1 to 3 for patients receiving capecitabine tablets monotherapy in the metastatic setting. Grade 1 is characterized by any of the following: numbness, dysesthesia/paresthesia, tingling, painless swelling or erythema of the hands and/or feet and/or discomfort which does not disrupt normal activities. Grade 2 hand-and-foot syndrome is defined as painful erythema and swelling of the hands and/or feet and/or discomfort affecting the patient’s activities of daily living. Grade 3 hand-and-foot syndrome is defined as moist desquamation, ulceration, blistering or severe pain of the hands and/or feet and/or severe discomfort that causes the patient to be unable to work or perform activities of daily living. Persistent or severe hand-and-foot syndrome (grade 2 and above) can eventually lead to loss of fingerprints which could impact patient identification. If grade 2 or 3 hand-and-foot syndrome occurs, administration of capecitabine tablets should be interrupted until the event resolves or decreases in intensity to grade 1. Following grade 3 hand-and-foot syndrome, subsequent doses of capecitabine tablets should be decreased [see Dosage and Administration (2.3)].
5.8 Hyperbilirubinemia
In 875 patients with either metastatic breast or colorectal cancer who received at least one dose of capecitabine tablets 1250 mg/m2 twice daily as monotherapy for 2 weeks followed by a 1-week rest period, grade 3 (1.5-3 x ULN) hyperbilirubinemia occurred in 15.2% (n = 133) of patients and grade 4 (> 3 x ULN) hyperbilirubinemia occurred in 3.9% (n = 34) of patients. Of 566 patients who had hepatic metastases at baseline and 309 patients without hepatic metastases at baseline, grade 3 or 4 hyperbilirubinemia occurred in 22.8% and 12.3%, respectively. Of the 167 patients with grade 3 or 4 hyperbilirubinemia, 18.6% (n = 31) also had postbaseline elevations (grades 1 to 4, without elevations at baseline) in alkaline phosphatase and 27.5% (n = 46) had postbaseline elevations in transaminases at any time (not necessarily concurrent). The majority of these patients, 64.5% (n = 20) and 71.7% (n = 33), had liver metastases at baseline. In addition, 57.5% (n = 96) and 35.3% (n = 59) of the 167 patients had elevations (grades 1 to 4) at both prebaseline and postbaseline in alkaline phosphatase or transaminases, respectively. Only 7.8% (n = 13) and 3.0% (n = 5) had grade 3 or 4 elevations in alkaline phosphatase or transaminases.
In the 596 patients treated with capecitabine tablets as first-line therapy for metastatic colorectal cancer, the incidence of grade 3 or 4 hyperbilirubinemia was similar to the overall clinical trial safety database of capecitabine tablets monotherapy. The median time to onset for grade 3 or 4 hyperbilirubinemia in the colorectal cancer population was 64 days and median total bilirubin increased from 8 μm/L at baseline to 13 μm/L during treatment with capecitabine tablets. Of the 136 colorectal cancer patients with grade 3 or 4 hyperbilirubinemia, 49 patients had grade 3 or 4 hyperbilirubinemia as their last measured value, of which 46 had liver metastases at baseline.
In 251 patients with metastatic breast cancer who received a combination of capecitabine tablets and docetaxel, grade 3 (1.5 to 3 x ULN) hyperbilirubinemia occurred in 7% (n = 17) and grade 4 (> 3 x ULN) hyperbilirubinemia occurred in 2% (n = 5).
If drug-related grade 3 to 4 elevations in bilirubin occur, administration of capecitabine tablets should be immediately interrupted until the hyperbilirubinemia decreases to ≤ 3.0 x ULN [see recommended dose modifications under Dosage and Administration (2.3)].
5.9 Hematologic
In 875 patients with either metastatic breast or colorectal cancer who received a dose of 1250 mg/m2 administered twice daily as monotherapy for 2 weeks followed by a 1-week rest period, 3.2%, 1.7%, and 2.4% of patients had grade 3 or 4 neutropenia, thrombocytopenia or decreases in hemoglobin, respectively. In 251 patients with metastatic breast cancer who received a dose of capecitabine tablets in combination with docetaxel, 68% had grade 3 or 4 neutropenia, 2.8% had grade 3 or 4 thrombocytopenia, and 9.6% had grade 3 or 4 anemia.
Patients with baseline neutrophil counts of < 1.5 x 109/L and/or thrombocyte counts of < 100 x 109/L should not be treated with capecitabine tablets. If unscheduled laboratory assessments during a treatment cycle show grade 3 or 4 hematologic toxicity, treatment with capecitabine tablets should be interrupted.
5.10 Geriatric Patients
Patients ≥ 80 years old may experience a greater incidence of grade 3 or 4 adverse reactions. In 875 patients with either metastatic breast or colorectal cancer who received capecitabine tablets monotherapy, 62% of the 21 patients ≥ 80 years of age treated with capecitabine tablets experienced a treatment-related grade 3 or 4 adverse event: diarrhea in 6 (28.6%), nausea in 3 (14.3%), hand-and-foot syndrome in 3 (14.3%), and vomiting in 2 (9.5%) patients. Among the 10 patients 70 years of age and greater (no patients were > 80 years of age) treated with capecitabine tablets in combination with docetaxel, 30% (3 out of 10) of patients experienced grade 3 or 4 diarrhea and stomatitis, and 40% (4 out of 10) experienced grade 3 hand-and-foot syndrome.
Among the 67 patients ≥ 60 years of age receiving capecitabine tablets in combination with docetaxel, the incidence of grade 3 or 4 treatment-related adverse reactions, treatment-related serious adverse reactions, withdrawals due to adverse reactions, treatment discontinuations due to adverse reactions and treatment discontinuations within the first two treatment cycles was higher than in the < 60 years of age patient group.
In 995 patients receiving capecitabine tablets as adjuvant therapy for Dukes’ C colon cancer after resection of the primary tumor, 41% of the 398 patients ≥ 65 years of age treated with capecitabine tablets experienced a treatment-related grade 3 or 4 adverse event: hand-and-foot syndrome in 75 (18.8%), diarrhea in 52 (13.1%), stomatitis in 12 (3.0%), neutropenia/granulocytopenia in 11 (2.8%), vomiting in 6 (1.5%), and nausea in 5 (1.3%) patients. In patients ≥ 65 years of age (all randomized population; capecitabine 188 patients, 5-FU/LV 208 patients) treated for Dukes’ C colon cancer after resection of the primary tumor, the hazard ratios for disease-free survival and overall survival for capecitabine tablets compared to 5-FU/LV were 1.01 (95% C.I. 0.80 - 1.27) and 1.04 (95% C.I. 0.79 - 1.37), respectively.
5.11 Hepatic Insufficiency
Patients with mild to moderate hepatic dysfunction due to liver metastases should be carefully monitored when capecitabine tablets are administered. The effect of severe hepatic dysfunction on the disposition of capecitabine tablets is not known [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

6 ADVERSE REACTIONS
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.
6.1 Adjuvant Colon Cancer
Table 4 shows the adverse reactions occurring in ≥ 5% of patients from one phase 3 trial in patients with Dukes’ C colon cancer who received at least one dose of study medication and had at least one safety assessment. A total of 995 patients were treated with 1250 mg/m2 twice a day of capecitabine tablets administered for 2 weeks followed by a 1-week rest period, and 974 patients were administered 5-FU and leucovorin (20 mg/m2 leucovorin IV followed by 425 mg/m2 IV bolus 5-FU on days 1-5 every 28 days). The median duration of treatment was 164 days for capecitabine-treated patients and 145 days for 5-FU/LV-treated patients. A total of 112 (11%) and 73 (7%) capecitabine and 5-FU/LV-treated patients, respectively, discontinued treatment because of adverse reactions. A total of 18 deaths due to all causes occurred either on study or within 28 days of receiving study drug: 8 (0.8%) patients randomized to capecitabine tablets and 10 (1.0%) randomized to 5-FU/LV.
Table 5 shows grade 3/4 laboratory abnormalities occurring in ≥ 1% of patients from one phase 3 trial in patients with Dukes’ C colon cancer who received at least one dose of study medication and had at least one safety assessment.

Table 5. Percent Incidence of Grade 3/4 Laboratory Abnormalities Reported in ≥ 1% of Patients Receiving Capecitabine Tablets Monotherapy for Adjuvant Treatment of Colon Cancer (Safety Population) - * The incidence of grade 3/4 white blood cell abnormalities was 1.3% in the capecitabine tablets arm and 4.9% in the IV 5-FU/LV arm.
- † It should be noted that grading was according to NCIC CTC Version 1 (May, 1994). In the NCIC-CTC Version 1, hyperbilirubinemia grade 3 indicates a bilirubin value of 1.5 to 3.0 × upper limit of normal (ULN) range, and grade 4 a value of > 3.0 × ULN. The NCI CTC Version 2 and above define a grade 3 bilirubin value of > 3.0 to 10.0 × ULN, and grade 4 values > 10.0 × ULN.

Monotherapy
Table 6 shows the adverse reactions occurring in ≥ 5% of patients from pooling the two phase 3 trials in first line metastatic colorectal cancer. A total of 596 patients with metastatic colorectal cancer were treated with 1250 mg/m2 twice a day of capecitabine tablets administered for 2 weeks followed by a 1-week rest period, and 593 patients were administered 5-FU and leucovorin in the Mayo regimen (20 mg/m2 leucovorin IV followed by 425 mg/m2 IV bolus 5-FU, on days 1-5, every 28 days). In the pooled colorectal database the median duration of treatment was 139 days for capecitabine-treated patients and 140 days for 5-FU/LV-treated patients. A total of 78 (13%) and 63 (11%) capecitabine and 5-FU/LV-treated patients, respectively, discontinued treatment because of adverse reactions/intercurrent illness. A total of 82 deaths due to all causes occurred either on study or within 28 days of receiving study drug: 50 (8.4%) patients randomized to capecitabine tablets and 32 (5.4%) randomized to 5-FU/LV.

In Combination with Docetaxel
The following data are shown for the combination study with capecitabine tablets and docetaxel in patients with metastatic breast cancer in Table 7 and Table 8. In the capecitabine tablets and docetaxel combination arm the treatment was capecitabine tablets administered orally 1250 mg/m2 twice daily as intermittent therapy (2 weeks of treatment followed by 1 week without treatment) for at least 6 weeks and docetaxel administered as a 1-hour intravenous infusion at a dose of 75 mg/m2 on the first day of each 3-week cycle for at least 6 weeks. In the monotherapy arm docetaxel was administered as a 1-hour intravenous infusion at a dose of 100 mg/m2 on the first day of each 3-week cycle for at least 6 weeks. The mean duration of treatment was 129 days in the combination arm and 98 days in the monotherapy arm. A total of 66 patients (26%) in the combination arm and 49 (19%) in the monotherapy arm withdrew from the study because of adverse reactions. The percentage of patients requiring dose reductions due to adverse reactions was 65% in the combination arm and 36% in the monotherapy arm. The percentage of patients requiring treatment interruptions due to adverse reactions in the combination arm was 79%. Treatment interruptions were part of the dose modification scheme for the combination therapy arm but not for the docetaxel monotherapy-treated patients.

Altered coagulation parameters and/or bleeding have been reported in patients taking capecitabine tablets concomitantly with coumarin-derivative anticoagulants such as warfarin and phenprocoumon [see Boxed Warning]. These events occurred within several days and up to several months after initiating capecitabine tablets therapy and, in a few cases, within 1 month after stopping capecitabine tablets. These events occurred in patients with and without liver metastases. In a drug interaction study with single-dose warfarin administration, there was a significant increase in the mean AUC of S-warfarin [see Clinical Pharmacology (12.3)]. The maximum observed INR value increased by 91%. This interaction is probably due to an inhibition of cytochrome P450 2C9 by capecitabine and/or its metabolites.
Phenytoin
The level of phenytoin should be carefully monitored in patients taking capecitabine tablets and phenytoin dose may need to be reduced [see Dosage and Administration (2.3)]. Postmarketing reports indicate that some patients receiving capecitabine tablets and phenytoin had toxicity associated with elevated phenytoin levels. Formal drug-drug interaction studies with phenytoin have not been conducted, but the mechanism of interaction is presumed to be inhibition of the CYP2C9 isoenzyme by capecitabine and/or its metabolites.
Leucovorin
The concentration of 5-fluorouracil is increased and its toxicity may be enhanced by leucovorin. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly leucovorin and fluorouracil.
CYP2C9 Substrates
Other than warfarin, no formal drug-drug interaction studies between capecitabine tablets and other CYP2C9 substrates have been conducted. Care should be exercised when capecitabine tablets are coadministered with CYP2C9 substrates.
Allopurinol
Concomitant use with allopurinol may decrease concentration of capecitabine’s active metabolites [see Clinical Pharmacology (12.3)], which may decrease capecitabine tablets efficacy. Avoid the use of allopurinol during treatment with capecitabine tablets.
7.2 Drug-Food Interaction
Food was shown to reduce both the rate and extent of absorption of capecitabine [see Clinical Pharmacology (12.3)]. In all clinical trials, patients were instructed to administer capecitabine tablets within 30 minutes after a meal. It is recommended that capecitabine tablets be administered with food [see Dosage and Administration (2)].

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
Based on findings in animal reproduction studies and its mechanism of action,capecitabine tablets can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. Limited available human data are not sufficient to inform the drug-associated risk during pregnancy. In animal reproduction studies, administration of capecitabine to pregnant animals during the period of organogenesis caused embryo lethality and teratogenicity in mice and embryo lethality in monkeys at 0.2 and 0.6 times the exposure (AUC) in patients receiving the recommended dose respectively [see Data]. Apprise pregnant women of the potential risk to a fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data
Animal Data
Oral administration of capecitabine to pregnant mice during the period of organogenesis at a dose of 198 mg/kg/day caused malformations and embryo lethality. In separate pharmacokinetic studies, this dose in mice produced 5’-DFUR AUC values that were approximately 0.2 times the AUC values in patients administered the recommended daily dose. Malformations in mice included cleft palate, anophthalmia, microphthalmia, oligodactyly, polydactyly, syndactyly, kinky tail and dilation of cerebral ventricles. Oral administration of capecitabine to pregnant monkeys during the period of organogenesis at a dose of 90 mg/kg/day, caused fetal lethality. This dose produced 5’-DFUR AUC values that were approximately 0.6 times the AUC values in patients administered the recommended daily dose.
8.2 Lactation
Risk Summary
There is no information regarding the presence of capecitabine in human milk, or on its effects on milk production or the breast-fed infant. Capecitabine metabolites were present in the milk of lactating mice [see Data]. Because of the potential for serious adverse reactions from capecitabine exposure in breast-fed infants, advise women not to breastfeed during treatment with capecitabine tablets and for 2 weeks after the final dose.
8.3 Females and Males of Reproductive Potential
Pregnancy Testing
Pregnancy testing is recommended for females of reproductive potential prior to initiating capecitabine tablets.
Contraception
Females
Capecitabine tablets can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the final dose of capecitabine tablets.
Males
Based on genetic toxicity findings, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months following the last dose of capecitabine tablets [see Nonclinical Toxicology (13.1)].
Infertility
Based on animal studies, capecitabine tablets may impair fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
The safety and effectiveness of capecitabine tablets in pediatric patients have not been established. No clinical benefit was demonstrated in two single arm trials in pediatric patients with newly diagnosed brainstem gliomas and high grade gliomas. In both trials, pediatric patients received an investigational pediatric formulation of capecitabine concomitantly with and following completion of radiation therapy (total dose of 5580 cGy in 180 cGy fractions). The relative bioavailability of the investigational formulation to capecitabine tablets was similar.
The first trial was conducted in 22 pediatric patients (median age 8 years, range 5-17 years) with newly diagnosed non-disseminated intrinsic diffuse brainstem gliomas and high grade gliomas. In the dose-finding portion of the trial, patients received capecitabine with concomitant radiation therapy at doses ranging from 500 mg/m2 to 850 mg/m2 every 12 hours for up to 9 weeks. After a 2 week break, patients received 1250 mg/m2 capecitabine every 12 hours on Days 1-14 of a 21-day cycle for up to 3 cycles. The maximum tolerated dose (MTD) of capecitabine administered concomitantly with radiation therapy was 650 mg/m2 every 12 hours. The major dose limiting toxicities were palmar-plantar erythrodysesthesia and alanine aminotransferase (ALT) elevation.
The second trial was conducted in 34 additional pediatric patients with newly diagnosed non-disseminated intrinsic diffuse brainstem gliomas (median age 7 years, range 3-16 years) and 10 pediatric patients who received the MTD of capecitabine in the dose-finding trial and met the eligibility criteria for this trial. All patients received 650 mg/m2 capecitabine every 12 hours with concomitant radiation therapy for up to 9 weeks. After a 2 week break, patients received 1250 mg/m2 capecitabine every 12 hours on Days 1-14 of a 21-day cycle for up to 3 cycles.
There was no improvement in one-year progression-free survival rate and one-year overall survival rate in pediatric patients with newly diagnosed intrinsic brainstem gliomas who received capecitabine relative to a similar population of pediatric patients who participated in other clinical trials.
The adverse reaction profile of capecitabine was consistent with the known adverse reaction profile in adults, with the exception of laboratory abnormalities which occurred more commonly in pediatric patients. The most frequently reported laboratory abnormalities (per-patient incidence ≥ 40%) were increased ALT (75%), lymphocytopenia (73%), leukopenia (73%), hypokalemia (68%), thrombocytopenia (57%), hypoalbuminemia (55%), neutropenia (50%), low hematocrit (50%), hypocalcemia (48%), hypophosphatemia (45%) and hyponatremia (45%).
8.5 Geriatric Use
Physicians should pay particular attention to monitoring the adverse effects of capecitabine tablets in the elderly [see Warnings and Precautions (5.10)].
8.6 Hepatic Insufficiency
Exercise caution when patients with mild to moderate hepatic dysfunction due to liver metastases are treated with capecitabine tablets. The effect of severe hepatic dysfunction on capecitabine tablets is not known [see Warnings and Precautions (5.11) and Clinical Pharmacology (12.3)].
8.7 Renal Insufficiency
Patients with moderate (creatinine clearance = 30 to 50 mL/min) and severe (creatinine clearance < 30 mL/min) renal impairment showed higher exposure for capecitabine, 5-DFUR, and FBAL than in those with normal renal function [see Contraindications (4.2), Warnings and Precautions (5.5), Dosage and Administration (2.4), and Clinical Pharmacology (12.3)].
-
10 OVERDOSAGE
The manifestations of acute overdose would include nausea, vomiting, diarrhea, gastrointestinal irritation and bleeding, and bone marrow depression. Medical management of overdose should include customary supportive medical interventions aimed at correcting the presenting clinical manifestations. Although no clinical experience using dialysis as a treatment for capecitabine tablets overdose has been reported, dialysis may be of benefit in reducing circulating concentrations of 5’-DFUR, a low–molecular-weight metabolite of the parent compound.
Single doses of capecitabine tablets were not lethal to mice, rats, and monkeys at doses up to 2000 mg/kg (2.4, 4.8, and 9.6 times the recommended human daily dose on a mg/m2 basis).

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Enzymes convert capecitabine to 5-fluorouracil (5-FU) in vivo. Both normal and tumor cells metabolize 5-FU to 5-fluoro-2’-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP). These metabolites cause cell injury by two different mechanisms. First, FdUMP and the folate cofactor, N5-10-methylenetetrahydrofolate, bind to thymidylate synthase (TS) to form a covalently bound ternary complex. This binding inhibits the formation of thymidylate from 2’-deoxyuridylate. Thymidylate is the necessary precursor of thymidine triphosphate, which is essential for the synthesis of DNA, so that a deficiency of this compound can inhibit cell division. Second, nuclear transcriptional enzymes can mistakenly incorporate FUTP in place of uridine triphosphate (UTP) during the synthesis of RNA. This metabolic error can interfere with RNA processing and protein synthesis.
12.3 Pharmacokinetics
Absorption
Following oral administration of 1255 mg/m2 BID to cancer patients, capecitabine reached peak blood levels in about 1.5 hours (Tmax) with peak 5-FU levels occurring slightly later, at 2 hours. Food reduced both the rate and extent of absorption of capecitabine with mean Cmax and AUC0-∞ decreased by 60% and 35%, respectively. The Cmax and AUC0-∞ of 5-FU were also reduced by food by 43% and 21%, respectively. Food delayed Tmax of both parent and 5-FU by 1.5 hours [see Warnings and Precautions (5), Dosage and Administration (2), and Drug-Food Interaction (7.2)].
The pharmacokinetics of capecitabine tablets and its metabolites have been evaluated in about 200 cancer patients over a dosage range of 500 to 3500 mg/m2/day. Over this range, the pharmacokinetics of capecitabine tablets and its metabolite, 5’-DFCR were dose proportional and did not change over time. The increases in the AUCs of 5’-DFUR and 5-FU, however, were greater than proportional to the increase in dose and the AUC of 5-FU was 34% higher on day 14 than on day 1. The interpatient variability in the Cmax and AUC of 5-FU was greater than 85%.
Distribution
Plasma protein binding of capecitabine and its metabolites is less than 60% and is not concentration-dependent. Capecitabine was primarily bound to human albumin (approximately 35%). Capecitabine tablets have a low potential for pharmacokinetic interactions related to plasma protein binding.
Bioactivation and Metabolism
Capecitabine is extensively metabolized enzymatically to 5-FU. In the liver, a 60 kDa carboxylesterase hydrolyzes much of the compound to 5’-deoxy-5-fluorocytidine (5’-DFCR). Cytidine deaminase, an enzyme found in most tissues, including tumors, subsequently converts 5’-DFCR to 5’-DFUR. The enzyme, thymidine phosphorylase (dThdPase), then hydrolyzes 5’-DFUR to the active drug 5-FU. Many tissues throughout the body express thymidine phosphorylase. Some human carcinomas express this enzyme in higher concentrations than surrounding normal tissues. Following oral administration of capecitabine tablets 7 days before surgery in patients with colorectal cancer, the median ratio of 5-FU concentration in colorectal tumors to adjacent tissues was 2.9 (range from 0.9 to 8.0). These ratios have not been evaluated in breast cancer patients or compared to 5-FU infusion.
The enzyme dihydropyrimidine dehydrogenase hydrogenates 5-FU, the product of capecitabine metabolism, to the much less toxic 5-fluoro-5, 6-dihydro-fluorouracil (FUH2). Dihydropyrimidinase cleaves the pyrimidine ring to yield 5-fluoro-ureido-propionic acid (FUPA). Finally, β-ureido-propionase cleaves FUPA to α-fluoro-β-alanine (FBAL) which is cleared in the urine.
In vitro enzymatic studies with human liver microsomes indicated that capecitabine and its metabolites (5’-DFUR, 5’-DFCR, 5-FU, and FBAL) did not inhibit the metabolism of test substrates by cytochrome P450 isoenzymes 1A2, 2A6, 3A4, 2C19, 2D6, and 2E1.
Excretion
Capecitabine and its metabolites are predominantly excreted in urine; 95.5% of administered capecitabine dose is recovered in urine. Fecal excretion is minimal (2.6%). The major metabolite excreted in urine is FBAL which represents 57% of the administered dose. About 3% of the administered dose is excreted in urine as unchanged drug. The elimination half-life of both parent capecitabine and 5-FU was about 0.75 hour.
Effect of Age, Gender, and Race on the Pharmacokinetics of Capecitabine
A population analysis of pooled data from the two large controlled studies in patients with metastatic colorectal cancer (n = 505) who were administered capecitabine tablets at 1250 mg/m2 twice a day indicated that gender (202 females and 303 males) and race (455 white/Caucasian patients, 22 black patients, and 28 patients of other race) have no influence on the pharmacokinetics of 5’-DFUR, 5-FU and FBAL. Age has no significant influence on the pharmacokinetics of 5’-DFUR and 5-FU over the range of 27 to 86 years. A 20% increase in age results in a 15% increase in AUC of FBAL [see Warnings and Precautions (5.11) and Dosage and Administration (2.4)].
Following oral administration of 825 mg/m2 capecitabine twice daily for 14 days, Japanese patients (n = 18) had about 36% lower Cmax and 24% lower AUC for capecitabine than the Caucasian patients (n = 22). Japanese patients had also about 25% lower Cmax and 34% lower AUC for FBAL than the Caucasian patients. The clinical significance of these differences is unknown. No significant differences occurred in the exposure to other metabolites (5’-DFCR, 5’-DFUR and 5-FU).
Effect of Hepatic Insufficiency
Capecitabine tablets have been evaluated in 13 patients with mild to moderate hepatic dysfunction due to liver metastases defined by a composite score including bilirubin, AST/ALT and alkaline phosphatase following a single 1255 mg/m2 dose of capecitabine tablets. Both AUC0-∞ and Cmax of capecitabine increased by 60% in patients with hepatic dysfunction compared to patients with normal hepatic function (n = 14). The AUC0-∞ and Cmax of 5-FU were not affected. In patients with mild to moderate hepatic dysfunction due to liver metastases, caution should be exercised when capecitabine tablets are administered. The effect of severe hepatic dysfunction on capecitabine tablets is not known [see Warnings and Precautions (5.11) and Use in Special Populations (8.6)].
Effect of Renal Insufficiency
Following oral administration of 1250 mg/m2 capecitabine twice a day to cancer patients with varying degrees of renal impairment, patients with moderate (creatinine clearance = 30 to 50 mL/min) and severe (creatinine clearance < 30 mL/min) renal impairment showed 85% and 258% higher systemic exposure to FBAL on day 1 compared to normal renal function patients (creatinine clearance > 80 mL/min). Systemic exposure to 5’-DFUR was 42% and 71% greater in moderately and severely renal impaired patients, respectively, than in normal patients. Systemic exposure to capecitabine was about 25% greater in both moderately and severely renal impaired patients [see Dosage and Administration (2.4), Contraindications (4.2), Warnings and Precautions (5.5), and Use in Special Populations (8.7)].
Effect of Capecitabine on the Pharmacokinetics of Warfarin
In four patients with cancer, chronic administration of capecitabine (1250 mg/m2 bid) with a single 20 mg dose of warfarin increased the mean AUC of S-warfarin by 57% and decreased its clearance by 37%. Baseline corrected AUC of INR in these 4 patients increased by 2.8-fold, and the maximum observed mean INR value was increased by 91% [see Boxed Warning and Drug Interactions (7.1)].
Effect of Antacids on the Pharmacokinetics of Capecitabine
When Maalox® (20 mL), an aluminum hydroxide- and magnesium hydroxide-containing antacid, was administered immediately after capecitabine tablets (1250 mg/m2, n = 12 cancer patients), AUC and Cmax increased by 16% and 35%, respectively, for capecitabine and by 18% and 22%, respectively, for 5’-DFCR. No effect was observed on the other three major metabolites (5’-DFUR, 5-FU, FBAL) of capecitabine tablets.
Effect of Allopurinol on Capecitabine
Published literature reported that concomitant use with allopurinol may decrease conversion of capecitabine to the active metabolites, FdUMP and FUTP; however, the clinical significance was not fully characterized.
Effect of Capecitabine on the Pharmacokinetics of Docetaxel and Vice Versa
A Phase 1 study evaluated the effect of capecitabine tablets on the pharmacokinetics of docetaxel (Taxotere®) and the effect of docetaxel on the pharmacokinetics of capecitabine tablets was conducted in 26 patients with solid tumors. Capecitabine tablets were found to have no effect on the pharmacokinetics of docetaxel (Cmax and AUC) and docetaxel has no effect on the pharmacokinetics of capecitabine and the 5-FU precursor 5’-DFUR.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Adequate studies investigating the carcinogenic potential of capecitabine have not been conducted. Capecitabine was not mutagenic in vitro to bacteria (Ames test) or mammalian cells (Chinese hamster V79/HPRT gene mutation assay). Capecitabine was clastogenic in vitro to human peripheral blood lymphocytes but not clastogenic in vivo to mouse bone marrow (micronucleus test). Fluorouracil causes mutations in bacteria and yeast. Fluorouracil also causes chromosomal abnormalities in the mouse micronucleus test in vivo.
In studies of fertility and general reproductive performance in female mice, oral capecitabine doses of 760 mg/kg/day (about 2300 mg/m2/day) disturbed estrus and consequently caused a decrease in fertility. In mice that became pregnant, no fetuses survived this dose. The disturbance in estrus was reversible. In males, this dose caused degenerative changes in the testes, including decreases in the number of spermatocytes and spermatids. In separate pharmacokinetic studies, this dose in mice produced 5’-DFUR AUC values about 0.7 times the corresponding values in patients administered the recommended daily dose.

14 CLINICAL STUDIES
14.1 Adjuvant Colon Cancer
A multicenter randomized, controlled phase 3 clinical trial in patients with Dukes’ C colon cancer (X-ACT) provided data concerning the use of capecitabine tablets for the adjuvant treatment of patients with colon cancer. The primary objective of the study was to compare disease-free survival (DFS) in patients receiving capecitabine tablets to those receiving IV 5-FU/LV alone. In this trial, 1987 patients were randomized either to treatment with capecitabine tablets 1250 mg/m2 orally twice daily for 2 weeks followed by a 1-week rest period, given as 3-week cycles for a total of 8 cycles (24 weeks) or IV bolus 5-FU 425 mg/m2 and 20 mg/m2 IV leucovorin on days 1 to 5, given as 4-week cycles for a total of 6 cycles (24 weeks). Patients in the study were required to be between 18 and 75 years of age with histologically-confirmed Dukes’ stage C colon cancer with at least one positive lymph node and to have undergone (within 8 weeks prior to randomization) complete resection of the primary tumor without macroscopic or microscopic evidence of remaining tumor. Patients were also required to have no prior cytotoxic chemotherapy or immunotherapy (except steroids), and have an ECOG performance status of 0 or 1 (KPS ≥ 70%), ANC ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, serum creatinine ≤ 1.5 ULN, total bilirubin ≤ 1.5 ULN, AST/ALT ≤ 2.5 ULN and CEA within normal limits at time of randomization.
The baseline demographics for capecitabine tablets and 5-FU/LV patients are shown in Table 10. The baseline characteristics were well-balanced between arms.

All patients with normal renal function or mild renal impairment began treatment at the full starting dose of 1250 mg/m2 orally twice daily. The starting dose was reduced in patients with moderate renal impairment (calculated creatinine clearance 30 to 50 mL/min) at baseline [see Dosage and Administration (2.4)]. Subsequently, for all patients, doses were adjusted when needed according to toxicity. Dose management for capecitabine tablets included dose reductions, cycle delays and treatment interruptions (see Table 11).

The median follow-up at the time of the analysis was 83 months (6.9 years). The hazard ratio for DFS for capecitabine tablets compared to 5-FU/LV was 0.88 (95% C.I. 0.77 - 1.01) (see Table 12 and Figure 1). Because the upper 2-sided 95% confidence limit of hazard ratio was less than 1.20, capecitabine tablets were non-inferior to 5-FU/LV. The choice of the non-inferiority margin of 1.20 corresponds to the retention of approximately 75% of the 5-FU/LV effect on DFS. The hazard ratio for capecitabine tablets compared to 5-FU/LV with respect to overall survival was 0.86 (95% C.I. 0.74 to 1.01). The 5-year overall survival rates were 71.4% for capecitabine tablets and 68.4% for 5-FU/LV (see Figure 2).

14.2 Metastatic Colorectal Cancer
General
The recommended dose of capecitabine tablets was determined in an open-label, randomized clinical study, exploring the efficacy and safety of continuous therapy with capecitabine (1331 mg/m2/day in two divided doses, n = 39), intermittent therapy with capecitabine (2510 mg/m2/day in two divided doses, n = 34), and intermittent therapy with capecitabine in combination with oral leucovorin (LV) (capecitabine 1657 mg/m2/day in two divided doses, n = 35; leucovorin 60 mg/day) in patients with advanced and/or metastatic colorectal carcinoma in the first-line metastatic setting. There was no apparent advantage in response rate to adding leucovorin to capecitabine tablets; however, toxicity was increased. Capecitabine tablets, 1250 mg/m2 twice daily for 14 days followed by a 1-week rest, was selected for further clinical development based on the overall safety and efficacy profile of the three schedules studied.
Monotherapy
Data from two open-label, multicenter, randomized, controlled clinical trials involving 1207 patients support the use of capecitabine tablets in the first-line treatment of patients with metastatic colorectal carcinoma. The two clinical studies were identical in design and were conducted in 120 centers in different countries. Study 1 was conducted in the U.S., Canada, Mexico, and Brazil; Study 2 was conducted in Europe, Israel, Australia, New Zealand, and Taiwan. Altogether, in both trials, 603 patients were randomized to treatment with capecitabine tablets at a dose of 1250 mg/m2 twice daily for 2 weeks followed by a 1-week rest period and given as 3-week cycles; 604 patients were randomized to treatment with 5-FU and leucovorin (20 mg/m2 leucovorin IV followed by 425 mg/m2 IV bolus 5-FU, on days 1 to 5, every 28 days).
In both trials, overall survival, time to progression and response rate (complete plus partial responses) were assessed. Responses were defined by the World Health Organization criteria and submitted to a blinded independent review committee (IRC). Differences in assessments between the investigator and IRC were reconciled by the sponsor, blinded to treatment arm, according to a specified algorithm. Survival was assessed based on a non-inferiority analysis.
The baseline demographics for capecitabine tablets and 5-FU/LV patients are shown in Table 13.

Capecitabine tablets were superior to 5-FU/LV for objective response rate in Study 1 and Study 2. The similarity of capecitabine tablets and 5-FU/LV in these studies was assessed by examining the potential difference between the two treatments. In order to assure that capecitabine tablets have a clinically meaningful survival effect, statistical analyses were performed to determine the percent of the survival effect of 5-FU/LV that was retained by capecitabine tablets. The estimate of the survival effect of 5-FU/LV was derived from a meta-analysis of ten randomized studies from the published literature comparing 5-FU to regimens of 5-FU/LV that were similar to the control arms used in these Studies 1 and 2. The method for comparing the treatments was to examine the worst case (95% confidence upper bound) for the difference between 5-FU/LV and capecitabine tablets, and to show that loss of more than 50% of the 5-FU/LV survival effect was ruled out. It was demonstrated that the percent of the survival effect of 5-FU/LV maintained was at least 61% for Study 2 and 10% for Study 1. The pooled result is consistent with a retention of at least 50% of the effect of 5-FU/LV. It should be noted that these values for preserved effect are based on the upper bound of the 5-FU/LV vs capecitabine tablets difference. These results do not exclude the possibility of true equivalence of capecitabine tablets to 5-FU/LV (see Table 14, Table 15, and Figure 3).
14.3 Breast Cancer
Capecitabine tablets have been evaluated in clinical trials in combination with docetaxel (Taxotere®) and as monotherapy.
In Combination With Docetaxel
The dose of capecitabine tablets used in the phase 3 clinical trial in combination with docetaxel was based on the results of a phase 1 study, where a range of doses of docetaxel administered in 3-week cycles in combination with an intermittent regimen of capecitabine tablets (14 days of treatment, followed by a 7-day rest period) were evaluated. The combination dose regimen was selected based on the tolerability profile of the 75 mg/m2 administered in 3-week cycles of docetaxel in combination with 1250 mg/m2 twice daily for 14 days of capecitabine tablets administered in 3-week cycles. The approved dose of 100 mg/m2 of docetaxel administered in 3-week cycles was the control arm of the phase 3 study.
Capecitabine tablets in combination with docetaxel were assessed in an open-label, multicenter, randomized trial in 75 centers in Europe, North America, South America, Asia, and Australia. A total of 511 patients with metastatic breast cancer resistant to, or recurring during or after an anthracycline-containing therapy, or relapsing during or recurring within 2 years of completing an anthracycline-containing adjuvant therapy were enrolled. Two hundred and fifty-five (255) patients were randomized to receive capecitabine tablets 1250 mg/m2 twice daily for 14 days followed by 1 week without treatment and docetaxel 75 mg/m2 as a 1-hour intravenous infusion administered in 3-week cycles. In the monotherapy arm, 256 patients received docetaxel 100 mg/m2 as a 1-hour intravenous infusion administered in 3-week cycles. Patient demographics are provided in Table 16.

Monotherapy
The antitumor activity of capecitabine tablets as a monotherapy was evaluated in an open-label single-arm trial conducted in 24 centers in the U.S. and Canada. A total of 162 patients with stage IV breast cancer were enrolled. The primary endpoint was tumor response rate in patients with measurable disease, with response defined as a ≥ 50% decrease in sum of the products of the perpendicular diameters of bidimensionally measurable disease for at least 1 month. Capecitabine tablets were administered at a dose of 1255 mg/m2 twice daily for 2 weeks followed by a 1-week rest period and given as 3-week cycles. The baseline demographics and clinical characteristics for all patients (n = 162) and those with measurable disease (n = 135) are shown in Table 18. Resistance was defined as progressive disease while on treatment, with or without an initial response, or relapse within 6 months of completing treatment with an anthracycline-containing adjuvant chemotherapy regimen.

What is the most important information I should know about capecitabine tablets?
Capecitabine tablets can cause serious side effects, including:
-
Capecitabine tablets can interact with blood thinner medicines, such as warfarin (COUMADIN®). Taking capecitabine tablets with these medicines can cause changes in how fast your blood clots and can cause bleeding that can lead to death. This can happen as soon as a few days after you start taking capecitabine tablets, or later during treatment, and possibly even within 1 month after you stop taking capecitabine tablets. Your risk may be higher because you have cancer, and if you are over 60 years of age.
- Before taking capecitabine tablets, tell your healthcare provider if you are taking warfarin (COUMADIN) or another blood thinner medicine.
- If you take warfarin (COUMADIN) or another blood thinner that is like warfarin (COUMADIN) during treatment with capecitabine tablets, your healthcare provider should do blood tests often, to check how fast your blood clots during and after you stop treatment with capecitabine tablets. Your healthcare provider may change your dose of the blood thinner medicine if needed.
See “What are the possible side effects of capecitabine tablets?” for more information about side effects.
What are capecitabine tablets?
Capecitabine tablets are a prescription medicine used to treat people with:
