5 WARNINGS AND PRECAUTIONS

5.1 Increased Risk of Bleeding With Concomitant Use of Vitamin K

Antagonists

Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking capecitabine tablets concomitantly with vitamin K antagonists, such as warfarin.

Clinically significant increases in PT and INR have been reported in patients who were on stable doses of oral vitamin K antagonists at the time capecitabine tablets was introduced. These events occurred within several days and up to several months after initiating capecitabine tablets and, in a few cases, within 1 month after stopping capecitabine tablets.

These events occurred in patients with and without liver metastases.Monitor INR more frequently and adjust the dose of the vitamin K antagonist as appropriate [see Drug Interactions (7.1)].

5.2 Serious Adverse Reactions from Dihydropyrimidine Dehydrogenase (DPD)

Deficiency

Patients with certain homozygous or compound heterozygous variants in the DPYD gene known to result in complete or near complete absence of DPD activity (complete DPD deficiency) are at increased risk for acute early-onset toxicity and serious, including fatal, adverse reactions due to capecitabine tablets (e.g., mucositis, diarrhea, neutropenia, and neurotoxicity). Patients with partial DPD activity (partial DPD deficiency) may also have increased risk of serious, including fatal, adverse reactions.

Capecitabine tablets is not recommended for use in patients known to have certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency.

Withhold or permanently discontinue capecitabine tablets based on clinical assessment of the onset, duration, and severity of the observed adverse reactions in patients with evidence of acute early- onset or unusually severe reactions, which may indicate complete DPD deficiency. No capecitabine tablets dose has been proven safe for patients with complete DPD deficiency. There are insufficient data to recommend a specific dose in patients with partial DPD deficiency.

Consider testing for genetic variants of DPYD prior to initiating capecitabine tablets to reduce the risk of serious adverse reactions if the patient’s clinical status permits and based on clinical judgement [see Clinical Pharmacology (12.5)]. Serious adverse reactions may still occur even if no DPYD variants are identified.

An FDA-authorized test for the detection of genetic variants of DPYD to identify patients at risk of serious adverse reactions due to increased systemic exposure to capecitabine tablets is not currently available. Currently available tests used to identify DPYD variants may vary in accuracy and design (e.g., which DPYD variant(s) they identify).

5.3 Cardiotoxicity

Cardiotoxicity can occur with capecitabine tablets. Myocardial infarction/ischemia, angina, dysrhythmias, cardiac arrest, cardiac failure, sudden death, electrocardiographic changes, and cardiomyopathy have been reported with capecitabine tablets. These adverse reactions may be more common in patients with a prior history of coronary artery disease.

Withhold capecitabine tablets for cardiotoxicity as appropriate [see Dosage and Administration (2.5)]. The safety of resumption of capecitabine tablets in patients with cardiotoxicity that has resolved have not been established.

5.4 Diarrhea

Diarrhea, sometimes severe, can occur with capecitabine tablets. In 875 patients with metastatic breast or colorectal cancer who received capecitabine tablets as a single agent, the median time to first occurrence of grade 2 to 4 diarrhea was 34 days (range: 1 day to 1 year).

The median duration of grade 3 to 4 diarrhea was 5 days.Withhold capecitabine tablets and then resume at same or reduced dose or permanently discontinue based on severity and occurrence [see Dosage and Administration (2.5)].

5.5 Dehydration

Dehydration can occur with capecitabine tablets. Patients with anorexia, asthenia, nausea, vomiting, or diarrhea may be at an increased risk of developing dehydration with capecitabine tablets. Optimize hydration before startingcapecitabine tablets. Monitor hydration status and kidney function at baseline and as clinically indicated. Withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence [see Dosage and Administration (2.5)].

5.6 Renal Toxicity

Serious renal failure, sometimes fatal, can occur with capecitabine tablets. Renal impairment or coadministration of capecitabine tablets with other products known to cause renal toxicity may increase the risk of renal toxicity [see Drug Interactions (7.3)].

Monitor renal function at baseline and as clinically indicated. Optimize hydration before starting capecitabine tablets. Withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence [see Dosage and Administration (2.5)].

5.7 Serious Skin Toxicities

Severe cutaneous adverse reactions (SCARs), including Stevens-Johnson Syndrome and toxic epidermal necrolysis (TEN), which can be fatal, can occur with capecitabine tablets [see Adverse Reactions (6.2)].

Monitor for new or worsening serious skin reactions. Permanently discontinue capecitabine tablets for severe cutaneous adverse reactions.

5.8 Palmar-Plantar Erythrodysesthesia Syndrome

Palmar-plantar erythrodysesthesia syndrome (PPES) can occur with capecitabine tablets.

In patients with metastatic breast or colorectal cancer who received capecitabine tablets as a single agent, the median time to onset of grades 1 to 3 PPES was 2.6 months (range: 11 days to 1 year).

Withhold capecitabine tablets and then resume at same or reduced dose or permanently discontinue based on severity and occurrence [see Dosage and Administration (2.5)].

5.9 Myelosuppression

Myelosuppression can occur with capecitabine tablets.

In the 875 patients with metastatic breast or colorectal cancer who received capecitabine tablets as a single agent, 3.2% had grade 3 or 4 neutropenia, 1.7% had grade 3 or 4 thrombocytopenia, and 2.4% had grade 3 or 4 anemia.

In the 251 patients with metastatic breast cancer who received capecitabine tablets with docetaxel, 68% had grade 3 or 4 neutropenia, 2.8% had grade 3 or 4 thrombocytopenia, and 10% had grade 3 or 4 anemia.

Necrotizing enterocolitis (typhlitis) has been reported. Consider typhlitis in patients with fever, neutropenia and abdominal pain.

Monitor complete blood count at baseline and before each cycle. Capecitabine tablets is not recommended if baseline neutrophil count <1.5 x 109/L or platelet count <100 x 109/L. For grade 3 to 4 myelosuppression, withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on occurrence [see Dosage and Administration (2.5)].

5.10 Hyperbilirubinemia

Hyperbilirubinemia can occur with capecitabine tablets. In the 875 patients with metastatic breast or colorectal cancer who received capecitabine tablets as a single agent, grade 3 hyperbilirubinemia occurred in 15% of patients and grade 4 hyperbilirubinemia occurred in 3.9%. Of the 566 patients who had hepatic metastases at baseline and the 309 patients without hepatic metastases at baseline, grade 3 or 4 hyperbilirubinemia occurred in 23% and 12%, respectively. Of these 167 patients with grade 3 or 4 hyperbilirubinemia, 19% had postbaseline increased alkaline phosphatase and 28% had postbaseline increased transaminases at any time (not necessarily concurrent). The majority of these patients with increased transaminases or alkaline phosphatase had liver metastases at baseline. In addition, 58% and 35% of the 167 patients with grade 3 or 4 hyperbilirubinemia had pre- and postbaseline increased alkaline phosphatase or transaminases (grades 1 to 4), respectively. Only 8% (n=13) and 3% (n=5) had grade 3 or 4 increased alkaline phosphatase or transaminases.

In the 596 patients who received capecitabine tablets for metastatic colorectal cancer, the incidence of grade 3 or 4 hyperbilirubinemia was similar to that observed for the pooled population of patients with metastatic breast and colorectal cancer. The median time to onset for grade 3 or 4 hyperbilirubinemia 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 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 the 251 patients with metastatic breast cancer who receivedcapecitabine tablets with docetaxel, grade 3 hyperbilirubinemia occurred in 7% and grade 4 hyperbilirubinemia occurred in 2%.

Withhold capecitabine tablets and then resume at a same or reduced dose, or permanently discontinue, based on occurrence [see Dosage and Administration (2.5)]. Patients with Grade 3-4 hyperbilirubinemia may resume treatment once the event is Grade 2 or less than three times the upper limit of normal, using the percent of current dose as shown in Table 1 [see Dosage and Administration (2.5)].

5.11 Embryo-Fetal Toxicity

Based on findings from animal reproduction studies and its mechanism of action, capecitabine tablets can cause fetal harm when administered to a pregnant woman. Insufficient data is available on capecitabine tablets use in pregnant women to evaluate a drug-associated risk. 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 human exposure (AUC) in patients who received a dosage of 1,250 mg/m2 twice daily, respectively.

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with capecitabine tablets and for 6 months following the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with capecitabine tablets and for 3 months following the last dose [see Use in Specific Populations (8.1, 8.3) ## 5.12 Eye Irritation, Skin Rash, and Other Adverse Reactions from Exposure to Crushed Tablets In instances of exposure to crushed capecitabine tablets, the following adverse reactions have been reported: eye irritation and swelling, skin rash, diarrhea, paresthesia, headache, gastric irritation, vomiting and nausea. Advise patients not to cut or crush tablets If capecitabine tablets 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 [see Dosage and Administration (2.7)]. The safety and effectiveness have not been established for the administration of crushed capecitabine tablets.

Skin & Subcutaneous Tissue: cutaneous lupus erythematosus, severe skin reactions such as Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis (TEN), persistent or severe PPES can eventually lead to loss of fingerprints

7 DRUG INTERACTIONS

7.1 Effect of Other Drugs on Capecitabine Tablets

Allopurinol

Concomitant use with allopurinol may decrease concentration of capecitabine’s active metabolites [see Clinical Pharmacology (12.3)], which may decrease efficacy. Avoid concomitant use of allopurinol with capecitabine tablets.

Leucovorin

The concentration of fluorouracil is increased and its toxicity may be enhanced by leucovorin, folic acid, or folate analog products. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly leucovorin and fluorouracil.

Instruct patients not to take products containing folic acid or folate analog products unless directed to do so by their healthcare provider.

7.2 Effect of Capecitabine Tablets on Other Drugs

CYP2C9 Substrates

Capecitabine tablets increased exposure of CYP2C9 substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates. Closely monitor for adverse reactions of CYP2C9 substrates where minimal concentration changes may lead to serious adverse reactions when used concomitantly with capecitabine tablets (e.g., anticoagulants, antidiabetic drugs).

Vitamin K Antagonists

Capecitabine tablets increases exposure of vitamin K antagonist [see Clinical Pharmacology (12.3)], which may alter coagulation parameters and/or bleeding and could result in death [see Warning and Precautions (5.1)]. These events may occur within days of treatment initiation and up to 1 month after discontinuation of capecitabine tablets.

Monitor INR more frequently and refer to the prescribing information of oral vitamin K antagonist for dosage adjustment, as appropriate, when capecitabine tablets is used concomitantly with vitamin K antagonist.

Phenytoin

Capecitabine tablets may increases exposure of phenytoin, which may increase the risk of adverse reactions related to phenytoin. Closely monitor phenytoin levels and refer to the prescribing information of phenytoin for dosage adjustment, as appropriate, when capecitabine tablets is used concomitantly with phenytoin.

7.3 Nephrotoxic Drugs

Due of the additive pharmacologic effect, concomitant use of capecitabine tablets with other drugs known to cause renal toxicity may increase the risk of renal toxicity [see Warnings and Precautions (5.6)]. Closely monitor for signs of renal toxicity when capecitabine tablets is used concomitantly with nephrotoxic drugs (e.g. platinum salts, irinotecan, methotrexate, intravenous bisphosphonates).

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Capecitabine is metabolized to fluorouracil in vivo. Both normal and tumor cells metabolize fluorouracil 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.

12.2 Pharmacodynamics

Population-based exposure-effect analyses demonstrated a positive association between AUC of fluorouracil and grade 3-4 hyperbilirubinemia.

12.3 Pharmacokinetics

The AUC of capecitabine and its metabolite 5’-DFCR increases proportionally over a dosage range of 500 mg/m2/day to 3,500 mg/m2/day (0.2 to 1.4 times the approved recommended dosage). The AUC of capecitabine’s metabolites 5’-DFUR and fluorouracil increased greater than proportional to the dose. The interpatient variability in the Cmax and AUC of fluorouracil was greater than 85%.

Absorption

Following oral administration of capecitabine tablets 1,255 mg/m2 orally twice daily (the recommended dosage when used as single agent), the median Tmax of capecitabine and its metabolite fluorouracil was approximately 1.5 hours and 2 hours, respectively.

Effect of Food

Following administration of a meal (breakfast medium-rich in fat and carbohydrates), the mean Cmax and AUC0-INF of capecitabine was decreased by 60% and 34%, respectively. The mean Cmax and AUC0-INF of fluorouracil were also decreased by 37 % and 12%, respectively. The Tmax of both capecitabine and fluorouracil was delayed by 1.5 hours.

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%).

Following oral administration of capecitabine tablets 7 days before surgery in patients with colorectal cancer, the median ratio of concentration for the active metabolite fluorouracil in colorectal tumors to adjacent tissues was 2.9 (range: 0.9 to 8.0).

Elimination

The elimination half-lives of capecitabine and fluorouracil were approximately 0.75 hour.

Metabolism

Capecitabine undergoes metabolism by carboxylesterase and is hydrolyzed to 5’-DFCR. 5’- DFCR is subsequently converted to 5’-DFUR by cytidine deaminase. 5’-DFUR is then hydrolized by thymidine phosphorylase (dThdPase) enzymes to the active metabolite fluorouracil.

Fluorouracil is subsequently metabolized by dihydropyrimidine dehydrogenase to 5-fluoro-5, 6- dihydro-fluorouracil (FUH2). The pyrimidine ring of FUH2 is cleaved by dihydropyrimidinase to yield 5-fluoro-ureido-propionic acid (FUPA). Finally, FUPA is cleaved by β-ureido-propionase to a-fluoro-β-alanine (FBAL).

Excretion

Following administration of radiolabeled capecitabine, 96% of the administered capecitabine dose was recovered in urine (3% unchanged and 57% as metabolite FBAL) and 2.6% in feces.

Specific Populations

Following administration of capecitabine tablets 825 mg/m2 orally twice daily for 14 days (0.66 times the recommended dosage), the Cmax and AUC of capecitabine decreased by 36% and 24%, respectively in Japanese patients (n=18) compared to White patients (n=22). The Cmax and AUC of FBAL decreased by approximately 25% and 34%, respectively in Japanese patients compared to White patients; however, the clinical significance of these differences is unknown. No clinically significant differences in the pharmacokinetics of 5’-DFCR, 5’-DFUR or fluorouracil were observed.

Following therapeutic doses of capecitabine tablets, no clinically meaningful difference in the pharmacokinetics of 5’-DFUR, fluorouracil or FBAL were observed based on sex (202 females and 303 males) and race (455 White, 22 Black, and 28 Other). No clinically meaningful difference on the pharmacokinetics of 5’-DFUR and fluorouracil were observed based on age (range: 27 to 86 years); however, the AUC of FBAL increased by 15% following a 20% increase in age.

Racial or Ethnic Groups

Following administration of capecitabine tablets 825 mg/m2 orally twice daily for 14 days (0.66 times the recommended dosage), the Cmax and AUC of capecitabine decreased by 36% and 24%, respectively in Japanese patients (n=18) compared to White patients (n=22). The Cmax and AUC of FBAL decreased by approximately 25% and 34%, respectively in Japanese patients compared to White patients; however, the clinical significance of these differences is unknown. No clinically significant differences in the pharmacokinetics of 5’-DFCR, 5’-DFUR or fluorouracil were observed.

Drug Interaction Studies

Clinical Studies

Effect of Capecitabine on Warfarin: In four patients with cancer, chronic administration of capecitabine tablets 1,250 mg/m2 twice daily with a single dose of warfarin 20 mg 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%.

Effect of Capecitabine on Celecoxib: Concomitant administration of multiple doses of capecitabine (capecitabine tablets 1,000 mg/m2 twice daily for 14 days) increased celecoxib (sensitive CYP2C9 substrate) AUC by 28%, Cmax by 24% and Ctrough by 30%.

Effect of Antacids on Capecitabine: When an aluminum hydroxide- and magnesium hydroxide- containing antacid was administered immediately after a capecitabine tablets dose of 1,250 mg/m2 in patients with cancer, 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, fluorouracil, FBAL) of capecitabine tablets.

Effect of Allopurinol on Capecitabine: Concomitant use with allopurinol may decrease conversion of capecitabine to the active metabolites, FdUMP and FUTP.

Effect of Capecitabine on Docetaxel and Effect of Docetaxel on Capecitabine: capecitabine tablets had no effect on the pharmacokinetics of docetaxel (Cmax and AUC) and docetaxel has no effect on the pharmacokinetics of capecitabine and the fluorouracil precursor 5’-DFUR.

In Vitro Studies

Cytochrome P450 (CYP) Enzymes: Capecitabine and its metabolites (5’-DFUR, 5’-DFCR, fluorouracil, and FBAL) did not inhibit CYP1A2, CYP2A6, CYP3A4, CYP2C19, CYP2D6, or CYP2E1 in vitro.

12.5 Pharmacogenomics

The DPYD gene encodes the enzyme DPD, which is responsible for the catabolism of >80% of fluorouracil. Approximately 3-5% of White populations have partial DPD deficiency and 0.2% of White populations have complete DPD deficiency, which may be due to certain genetic no function or decreased function variants in DPYD resulting in partial to complete or near complete absence of enzyme activity. DPD deficiency is estimated to be more prevalent in Black or African American populations compared to White populations. Insufficient information is available to estimate the prevalence of DPD deficiency in other populations.

Patients who are homozygous or compound heterozygous for no functionDPYD variants (i.e., carry two no function DPYD variants) or are compound heterozygous for a no function DPYD variant plus a decreased function DPYD variant have complete DPD deficiency and are at increased risk for acute early-onset of toxicity and serious life-threatening, or fatal adverse reactions due to increased systemic exposure to capecitabine tablets. Partial DPD deficiency can result from the presence of either two decreased functionDPYD variants or one normal function plus either a decreased function or a no functionDPYD variant. Patients with partial DPD deficiency may also be at an increased risk for toxicity from capecitabine tablets.

Four DPYD variants have been associated with impaired DPD activity in White populations, especially when present as homozygous or compound heterozygous variants: c.1905+1G>A (DPYD 2A), c.1679T>G (DPYD 13), c.2846A>T, and c.1129-5923C>G (HaplotypeB3). DPYD2A and DPYD13 are no function variants, and c.2846A>T and c.1129-5923C>G are decreased function variants. The decreased function DPYD variant c.557A>G is observed in individuals of African ancestry. This is not a complete listing of all DPYD variants that may result in DPD deficiency [see Warnings and Precautions (5.2)].

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 2,300 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.
