These Highlights Do Not Include All The Information Needed To Use Xeloda®

Prior to initiating XELODA, test patients for genetic variants of the DPYD gene unless immediate treatment is necessary. An FDA-authorized test for the detection of the DPYD gene to identify patients at risk of serious adverse reactions with XELODA 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).

Avoid use of XELODA in patients known to have certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency. No XELODA dose has been proven safe for patients with complete DPD deficiency. For patients with partial DPD deficiency, individualize the dosage and modify based on tolerability and intent of treatment [see Warnings and Precautions (5.1) ].

Storage and Handling

Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature]. KEEP TIGHTLY CLOSED.

XELODA is a hazardous drug. Follow applicable special handling and disposal procedures.¹

Diarrhea, sometimes severe, can occur with XELODA. In 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA and then resume at same or reduced dose or permanently discontinue based on severity and occurrence [see Dosage and Administration (2.5)].

Administer uridine triacetate within 96 hours for management of XELODA overdose.

Although no clinical experience using dialysis as a treatment for XELODA 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.

Capecitabine is a nucleoside metabolic inhibitor. The chemical name is 5'-deoxy-5-fluoro-N-[(pentyloxy) carbonyl]-cytidine and has a molecular formula of C₁₅H₂₂FN₃O₆ and a molecular weight of 359.35. Capecitabine has the following structural formula:

Capecitabine is a white to off-white crystalline powder with an aqueous solubility of 26 mg/mL at 20°C.

XELODA (capecitabine) is supplied as biconvex, oblong film-coated tablets for oral use. Each light peach-colored tablet contains 150 mg capecitabine and each peach-colored tablet contains 500 mg capecitabine. The inactive ingredients in XELODA include: anhydrous lactose, croscarmellose sodium, hydroxypropyl methylcellulose, microcrystalline cellulose, magnesium stearate and purified water. The peach or light peach film coating contains hydroxypropyl methylcellulose, talc, titanium dioxide, and synthetic yellow and red iron oxides.

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

XELODA is indicated for the:

• treatment of patients with advanced or metastatic breast cancer as a single agent if an anthracycline- or taxane-containing chemotherapy is not indicated.
• treatment of patients with advanced or metastatic breast cancer in combination with docetaxel after disease progression on prior anthracycline-containing chemotherapy.

The safety and effectiveness of XELODA in pediatric patients have not been established.

Safety and effectiveness were assessed, but not established in two single arm studies in 56 pediatric patients aged 3 months to <17 years with newly diagnosed 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 XELODA was similar.

The adverse reaction profile was consistent with that of 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%), hypokalemia (68%), thrombocytopenia (57%), hypoalbuminemia (55%), neutropenia (50%), low hematocrit (50%), hypocalcemia (48%), hypophosphatemia (45%) and hyponatremia (45%).

Of 7938 patients with colorectal cancer who were treated with XELODA, 33% were older than 65 years. Of the 4536 patients with metastatic breast cancer who were treated with XELODA, 18% were older than 65 years.

Of 1951 patients with gastric, esophageal, or gastrointestinal junction cancer who were treated with XELODA, 26% were older than 65 years.

Of 364 patients with pancreatic cancer who received adjuvant treatment with XELODA, 47% were 65 years or older.

No overall differences in efficacy were observed comparing older versus younger patients with colorectal cancer, gastric, esophageal or gastrointestinal junction cancer, or pancreatic cancer using the approved recommended dosages and treatment regimens.

Older patients experience increased gastrointestinal toxicity due to XELODA compared to younger patients. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly leucovorin and fluorouracil [see Drug Interactions (7.1)].

Round the recommended dosage for patients to the nearest 150 mg dose to provide whole XELODA tablets.

Swallow XELODA tablets whole with water within 30 minutes after a meal. Do not chew, cut, or crush XELODA tablets [see Warnings and Precautions (5.12)].

Take XELODA at the same time each day approximately 12 hours apart.

Do not take an additional dose after vomiting and continue with the next scheduled dose.

Do not take a missed dose and continue with the next scheduled dose.

XELODA is a hazardous drug. Follow applicable special handling and disposal procedures.¹

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

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

Serious renal failure, sometimes fatal, can occur with XELODA. Renal impairment or coadministration of XELODA 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 XELODA. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence [see Dosage and Administration (2.5)].

XELODA is contraindicated in patients with history of severe hypersensitivity reaction to fluorouracil or capecitabine [see Adverse Reactions (6.1)].

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Cardiotoxicity [see Warnings and Precautions (5.3)]
• Diarrhea [see Warnings and Precautions (5.4)]
• Dehydration [see Warnings and Precautions (5.5)]
• Renal Toxicity [see Warnings and Precautions (5.6)]
• Serious Skin Toxicities [see Warnings and Precautions (5.7)]
• Palmar-Plantar Erythrodysesthesia Syndrome [see Warnings and Precautions (5.8)]
• Myelosuppression [see Warnings and Precautions (5.9)]
• Hyperbilirubinemia [see Warnings and Precautions (5.10)]

• Allopurinol: Avoid concomitant use of allopurinol with XELODA. (7.1)
• Leucovorin: Closely monitor for toxicities when XELODA is coadministered with leucovorin. (7.1)
• CYP2C9 substrates: Closely monitor for adverse reactions when CYP2C9 substrates are coadministered with XELODA. (7.2)
• Vitamin K antagonists: Monitor INR more frequently and dose adjust oral vitamin K antagonist as appropriate
• Phenytoin: Closely monitor phenytoin levels in patients taking XELODA concomitantly with phenytoin and adjust the phenytoin dose as appropriate. (7.2)
• Nephrotoxic drugs: Closely monitor for signs of renal toxicity when XELODA is used concomitantly with nephrotoxic drugs. (7.3)

Myelosuppression can occur with XELODA.

In the 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA 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. XELODA is not recommended if baseline neutrophil count <1.5 × 10⁹/L or platelet count <100 × 10⁹/L. For grade 3 to 4 myelosuppression, withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on occurrence [see Dosage and Administration (2.5)].

The exposure of capecitabine and its inactive metabolites (5-DFUR and FBAL) increases in patients with CLcr <50 mL/min as determined by Cockcroft-Gault [see Clinical Pharmacology (12.3)]. Reduce the dosage for patients with CLcr of 30 to 50 mL/min [see Dosage and Administration (2.6)]. There is limited experience with XELODA in patients with CLcr <30 mL/min, and a dosage has not been established in those patients. If no treatment alternative exists, XELODA could be administered to such patients on an individual basis applying a reduced starting dose, close monitoring of a patient's clinical and biochemical data and dose modifications guided by observed adverse reactions.

XELODA is indicated for the:

• adjuvant treatment of patients with Stage III colon cancer as a single agent or as a component of a combination chemotherapy regimen.
• perioperative treatment of adults with locally advanced rectal cancer as a component of chemoradiotherapy.
• treatment of patients with unresectable or metastatic colorectal cancer as a single agent or as a component of a combination chemotherapy regimen.

XELODA is indicated for the adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen.

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

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 C_max and AUC of fluorouracil was greater than 85%.

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 function DPYD variants (i.e., carry two DPYD variants that results in no DPD enzyme activity) 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 with XELODA. Partial DPD deficiency can result from the presence of either two decreased function DPYD variants or one normal function plus either a decreased function or a no function DPYD variant. Patients with partial DPD deficiency may also be at an increased risk for toxicity from XELODA.

Several DPYD variants observed with variable frequency across populations have been associated with reduced or no DPD activity, especially when present as homozygous or compound heterozygous variants.These include c.1905+1G>A (DPYD *2A), c.1679T>G (DPYD *13), c.2846A>T, c.1129-5923C>G (Haplotype B3), and c557A>G. DPYD*2A and DPYD*13 are no function variants, and c.2846A>T, c.1129-5923C>G, and c557A>G are decreased function variants. This is not a complete listing of all DPYD variants that may result in DPD deficiency [see Warnings and Precautions (5.1)].

Due of the additive pharmacologic effect, concomitant use of XELODA 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 XELODA is used concomitantly with nephrotoxic drugs (e.g. platinum salts, irinotecan, methotrexate, intravenous bisphosphonates).

The efficacy of XELODA for the adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen was derived from a study in the published literature. XELODA was evaluated in ESPAC-4 trial, a two-group, open-label, multicenter, randomized trial, where the major efficacy outcome measure was overall survival.

The exposure of capecitabine increases in patients with mild to moderate hepatic impairment. The effect of severe hepatic impairment on the safety and pharmacokinetics of XELODA is unknown [see Clinical Pharmacology (12.3)]. Monitor patients with hepatic impairment more frequently for adverse reactions.

XELODA (capecitabine) is a nucleoside metabolic inhibitor indicated for:

Colorectal Cancer

• adjuvant treatment of patients with Stage III colon cancer as a single agent or as a component of a combination chemotherapy regimen. (1.1)
• perioperative treatment of adults with locally advanced rectal cancer as a component of chemoradiotherapy. (1.1)
• treatment of patients with unresectable or metastatic colorectal cancer as a single agent or as a component of a combination chemotherapy regimen. (1.1)

Breast Cancer

• treatment of patients with advanced or metastatic breast cancer as a single agent if an anthracycline- or taxane-containing chemotherapy is not indicated. (1.2)
• treatment of patients with advanced or metastatic breast cancer in combination with docetaxel after disease progression on prior anthracycline-containing chemotherapy. (1.2)

Gastric, Esophageal, or Gastroesophageal Junction Cancer

• treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen. (1.3)
• treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen. (1.3)

Pancreatic Cancer

• adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen. (1.4)

Hyperbilirubinemia can occur with XELODA. In the 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA 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 XELODA. 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 received XELODA with docetaxel, grade 3 hyperbilirubinemia occurred in 7% and grade 4 hyperbilirubinemia occurred in 2%.

Withhold XELODA 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)].

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, N^5-10-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.

• Cardiotoxicity: May be more common in patients with a prior history of coronary artery disease. Withhold XELODA for cardiotoxicity as appropriate. The safety of resumption of XELODA in patients with cardiotoxicity that has resolved has not been established. (2.5, 5.3)
• Diarrhea: Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.4)
• Dehydration: Optimize hydration before starting XELODA. Monitor hydration status and kidney function at baseline and as clinically indicated. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.5)
• Renal Toxicity: Monitor renal function at baseline and as clinically indicated. Optimize hydration before starting XELODA. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.6)
• Serious Skin Toxicities: Monitor for new or worsening serious skin reactions. Permanently discontinue XELODA in patients who experience a severe cutaneous adverse reaction. (5.7)
• Palmar-Plantar Erythrodysesthesia Syndrome: Withhold XELODA then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.8)
• Myelosuppression: Monitor complete blood count at baseline and before each cycle. XELODA is not recommended in patients with baseline neutrophil counts <1.5 × 10⁹/L or platelet counts <100 × 10⁹/L. For grade 3 or 4 myelosuppression, withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on occurrence. (2.5, 5.9)
• Hyperbilirubinemia: Patients with Grade 3-4 hyperbilirubinemia may resume treatment once the event is Grade 2 or less (≤3 × ULN), using the percent of current dose as shown in column 3 of Table 1 (2.5, 5.10)
• Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. (5.11, 8.1, 8.3)

Based on findings from animal reproduction studies and its mechanism of action, XELODA can cause fetal harm when administered to a pregnant woman. Insufficient data is available on XELODA 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 XELODA and for 6 months following the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with XELODA and for 3 months following the last dose [see Use in Specific Populations (8.1, 8.3)].

Refer to Sections 2.5 and 2.6 for information related to dosage modifications for adverse reactions and renal impairment (2.5 and 2.6).

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

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

Tablets, film-coated:

• 150 mg: biconvex, oblong, light-peach colored, with "XELODA" on one side and "150" on the other
• 500 mg: biconvex, oblong, peach colored, with "XELODA on one side and "500" on the other

The following adverse reactions have been identified during post-approval use of XELODA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Eye: lacrimal duct stenosis, corneal disorders including keratitis

Hepatobiliary: hepatic failure

Immune System Disorders: angioedema

Nervous System: toxic leukoencephalopathy

Renal & Urinary: acute renal failure secondary to dehydration including fatal outcome

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

• Lactation: Advise not to breastfeed. (8.2)
• Hepatic Impairment: Monitor patients with hepatic impairment more frequently for adverse reactions. (8.7)

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.

Advise the patient to read the FDA-approved patient labeling (Patient Information).

XELODA (capecitabine) tablets are supplied as follows:

• 150 mg, biconvex, oblong, film-coated, light peach tablets with "XELODA" on one side and "150" on the other; available in bottles of 60 tablets (NDC 61269-470-60), individually packaged in a carton.
• 500 mg, biconvex, oblong, film-coated, peach tablets with "XELODA" on one side and "500" on the other; available in bottles of 120 tablets (NDC 61269-475-12), individually packaged in a carton.

The recommended dosage of XELODA is 830 mg/m² orally twice daily for the first 21 days of each 28-day cycle until disease progression, unacceptable toxicity, or for a maximum 6 cycles in combination with gemcitabine 1,000 mg/m² administered intravenously on days 1, 8, and 15 of each cycle.

Refer to Prescribing Information for gemcitabine for additional dosing information as appropriate.

Reduce the dose of XELODA by 25% for patients with creatinine clearance (CLcr) of 30 to 50 mL/min as determined by Cockcroft-Gault equation. A dosage has not been established in patients with severe renal impairment (CLcr <30 mL/min) [see Use in Specific Populations (8.6)].

Monitor patients for adverse reactions and modify dosages of XELODA as described in Table 1. Do not replace missed doses of XELODA; instead resume XELODA with the next planned dosage.

When XELODA is administered with docetaxel, withhold XELODA and docetaxel until the requirements for resuming both XELODA and docetaxel are met. Refer to the Prescribing Information for docetaxel for additional dosing information as appropriate.

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

In patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA and then resume at same or reduced dose or permanently discontinue based on severity and occurrence [see Dosage and Administration (2.5)].

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.

XELODA is indicated for the:

• treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen.
• treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen.

The efficacy of XELODA for treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen was derived from studies in the published literature. XELODA was evaluated in REAL-2, a randomized non-inferiority, 2×2 factorial trial, where the major efficacy outcome measure was overall survival, and an additional randomized trial conducted by the North Central Cancer Treatment Group, where the major efficacy outcome measure was objective response rate.

The efficacy of XELODA for the treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen was derived from studies in the published literature. XELODA was evaluated in the ToGA trial [NCT01041404], an open-label, multicenter, randomized trial where the primary efficacy measure was overall survival.

Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking XELODA 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 XELODA was introduced. These events occurred within several days and up to several months after initiating XELODA and, in a few cases, within 1 month after stopping XELODA. 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)].

The recommended dosage of XELODA for unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer is:

• 625 mg/m² orally twice daily on days 1 to 21 of each 21-day cycle for a maximum of 8 cycles in combination with platinum-containing chemotherapy.
  
  OR
• 850 mg/m² or 1,000 mg/m² orally twice daily for the first 14 days of each 21-day cycle until disease progression or unacceptable toxicity in combination with oxaliplatin 130 mg/m² administered intravenously on day 1 of each cycle. Individualize the dose and dosing schedule of XELODA based on patient risk factors and adverse reactions.

The recommended dosage of XELODA for HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma is 1,000 mg/m² orally twice daily for the first 14 days of each 21-day cycle until disease progression or unacceptable toxicity in combination with cisplatin and trastuzumab.

Refer to the Prescribing Information for agents used in combination for additional dosing information as appropriate.

In instances of exposure to crushed XELODA 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 XELODA 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 XELODA tablets.

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 XELODA (e.g., mucositis, diarrhea, neutropenia, and neurotoxicity). Patients with partial DPD activity (partial DPD deficiency) may also have increased risk of serious or fatal, adverse reactions.

Prior to initiating XELODA, test patients for genetic variants of the DPYD gene unless immediate treatment is necessary [see Clinical Pharmacology (12.5) ]. Serious adverse reactions may still occur even if no DPYD variants are identified.

Avoid use of XELODA in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency.

Withhold or permanently discontinue XELODA based on clinical assessment of the onset, duration, and severity of adverse reactions in patients with evidence of acute early-onset or unusually severe reactions. No XELODA 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. For patients with partial DPD deficiency, individualize the dosage and modify based on tolerability and intent of treatment.

An FDA-authorized test for the detection of genetic variants of the DPYD gene to identify patients at risk of serious adverse reactions with XELODA treatment 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).

Increased risk of serious adverse reactions or death in patients with complete DPD deficiency

• Test patients for genetic variants of DPYD prior to initiating XELODA unless immediate treatment is necessary. Avoid use of XELODA in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency [see 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 XELODA concomitantly with oral vitamin K antagonists, such as warfarin [see Warnings and Precautions (5.2), Drug Interactions (7.2) ].

• Clinically significant increases in prothrombin time (PT) and international normalized ratio (INR) have been reported in patients who were on stable doses of a vitamin K antagonist at the time XELODA was introduced. 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 (7.2)].

Prior to initiating XELODA, test patients for genetic variants of the DPYD gene unless immediate treatment is necessary. An FDA-authorized test for the detection of the DPYD gene to identify patients at risk of serious adverse reactions with XELODA 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).

Avoid use of XELODA in patients known to have certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency. No XELODA dose has been proven safe for patients with complete DPD deficiency. For patients with partial DPD deficiency, individualize the dosage and modify based on tolerability and intent of treatment [see Warnings and Precautions (5.1) ].

Storage and Handling

Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature]. KEEP TIGHTLY CLOSED.

XELODA is a hazardous drug. Follow applicable special handling and disposal procedures.¹

Diarrhea, sometimes severe, can occur with XELODA. In 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA and then resume at same or reduced dose or permanently discontinue based on severity and occurrence [see Dosage and Administration (2.5)].

Administer uridine triacetate within 96 hours for management of XELODA overdose.

Although no clinical experience using dialysis as a treatment for XELODA 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.

Capecitabine is a nucleoside metabolic inhibitor. The chemical name is 5'-deoxy-5-fluoro-N-[(pentyloxy) carbonyl]-cytidine and has a molecular formula of C₁₅H₂₂FN₃O₆ and a molecular weight of 359.35. Capecitabine has the following structural formula:

Capecitabine is a white to off-white crystalline powder with an aqueous solubility of 26 mg/mL at 20°C.

XELODA (capecitabine) is supplied as biconvex, oblong film-coated tablets for oral use. Each light peach-colored tablet contains 150 mg capecitabine and each peach-colored tablet contains 500 mg capecitabine. The inactive ingredients in XELODA include: anhydrous lactose, croscarmellose sodium, hydroxypropyl methylcellulose, microcrystalline cellulose, magnesium stearate and purified water. The peach or light peach film coating contains hydroxypropyl methylcellulose, talc, titanium dioxide, and synthetic yellow and red iron oxides.

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

XELODA is indicated for the:

• treatment of patients with advanced or metastatic breast cancer as a single agent if an anthracycline- or taxane-containing chemotherapy is not indicated.
• treatment of patients with advanced or metastatic breast cancer in combination with docetaxel after disease progression on prior anthracycline-containing chemotherapy.

The safety and effectiveness of XELODA in pediatric patients have not been established.

Safety and effectiveness were assessed, but not established in two single arm studies in 56 pediatric patients aged 3 months to <17 years with newly diagnosed 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 XELODA was similar.

The adverse reaction profile was consistent with that of 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%), hypokalemia (68%), thrombocytopenia (57%), hypoalbuminemia (55%), neutropenia (50%), low hematocrit (50%), hypocalcemia (48%), hypophosphatemia (45%) and hyponatremia (45%).

Of 7938 patients with colorectal cancer who were treated with XELODA, 33% were older than 65 years. Of the 4536 patients with metastatic breast cancer who were treated with XELODA, 18% were older than 65 years.

Of 1951 patients with gastric, esophageal, or gastrointestinal junction cancer who were treated with XELODA, 26% were older than 65 years.

Of 364 patients with pancreatic cancer who received adjuvant treatment with XELODA, 47% were 65 years or older.

No overall differences in efficacy were observed comparing older versus younger patients with colorectal cancer, gastric, esophageal or gastrointestinal junction cancer, or pancreatic cancer using the approved recommended dosages and treatment regimens.

Older patients experience increased gastrointestinal toxicity due to XELODA compared to younger patients. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly leucovorin and fluorouracil [see Drug Interactions (7.1)].

Round the recommended dosage for patients to the nearest 150 mg dose to provide whole XELODA tablets.

Swallow XELODA tablets whole with water within 30 minutes after a meal. Do not chew, cut, or crush XELODA tablets [see Warnings and Precautions (5.12)].

Take XELODA at the same time each day approximately 12 hours apart.

Do not take an additional dose after vomiting and continue with the next scheduled dose.

Do not take a missed dose and continue with the next scheduled dose.

XELODA is a hazardous drug. Follow applicable special handling and disposal procedures.¹

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

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

Serious renal failure, sometimes fatal, can occur with XELODA. Renal impairment or coadministration of XELODA 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 XELODA. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence [see Dosage and Administration (2.5)].

XELODA is contraindicated in patients with history of severe hypersensitivity reaction to fluorouracil or capecitabine [see Adverse Reactions (6.1)].

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Cardiotoxicity [see Warnings and Precautions (5.3)]
• Diarrhea [see Warnings and Precautions (5.4)]
• Dehydration [see Warnings and Precautions (5.5)]
• Renal Toxicity [see Warnings and Precautions (5.6)]
• Serious Skin Toxicities [see Warnings and Precautions (5.7)]
• Palmar-Plantar Erythrodysesthesia Syndrome [see Warnings and Precautions (5.8)]
• Myelosuppression [see Warnings and Precautions (5.9)]
• Hyperbilirubinemia [see Warnings and Precautions (5.10)]

• Allopurinol: Avoid concomitant use of allopurinol with XELODA. (7.1)
• Leucovorin: Closely monitor for toxicities when XELODA is coadministered with leucovorin. (7.1)
• CYP2C9 substrates: Closely monitor for adverse reactions when CYP2C9 substrates are coadministered with XELODA. (7.2)
• Vitamin K antagonists: Monitor INR more frequently and dose adjust oral vitamin K antagonist as appropriate
• Phenytoin: Closely monitor phenytoin levels in patients taking XELODA concomitantly with phenytoin and adjust the phenytoin dose as appropriate. (7.2)
• Nephrotoxic drugs: Closely monitor for signs of renal toxicity when XELODA is used concomitantly with nephrotoxic drugs. (7.3)

Myelosuppression can occur with XELODA.

In the 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA 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. XELODA is not recommended if baseline neutrophil count <1.5 × 10⁹/L or platelet count <100 × 10⁹/L. For grade 3 to 4 myelosuppression, withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on occurrence [see Dosage and Administration (2.5)].

The exposure of capecitabine and its inactive metabolites (5-DFUR and FBAL) increases in patients with CLcr <50 mL/min as determined by Cockcroft-Gault [see Clinical Pharmacology (12.3)]. Reduce the dosage for patients with CLcr of 30 to 50 mL/min [see Dosage and Administration (2.6)]. There is limited experience with XELODA in patients with CLcr <30 mL/min, and a dosage has not been established in those patients. If no treatment alternative exists, XELODA could be administered to such patients on an individual basis applying a reduced starting dose, close monitoring of a patient's clinical and biochemical data and dose modifications guided by observed adverse reactions.

XELODA is indicated for the:

• adjuvant treatment of patients with Stage III colon cancer as a single agent or as a component of a combination chemotherapy regimen.
• perioperative treatment of adults with locally advanced rectal cancer as a component of chemoradiotherapy.
• treatment of patients with unresectable or metastatic colorectal cancer as a single agent or as a component of a combination chemotherapy regimen.

XELODA is indicated for the adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen.

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

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 C_max and AUC of fluorouracil was greater than 85%.

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 function DPYD variants (i.e., carry two DPYD variants that results in no DPD enzyme activity) 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 with XELODA. Partial DPD deficiency can result from the presence of either two decreased function DPYD variants or one normal function plus either a decreased function or a no function DPYD variant. Patients with partial DPD deficiency may also be at an increased risk for toxicity from XELODA.

Several DPYD variants observed with variable frequency across populations have been associated with reduced or no DPD activity, especially when present as homozygous or compound heterozygous variants.These include c.1905+1G>A (DPYD *2A), c.1679T>G (DPYD *13), c.2846A>T, c.1129-5923C>G (Haplotype B3), and c557A>G. DPYD*2A and DPYD*13 are no function variants, and c.2846A>T, c.1129-5923C>G, and c557A>G are decreased function variants. This is not a complete listing of all DPYD variants that may result in DPD deficiency [see Warnings and Precautions (5.1)].

Due of the additive pharmacologic effect, concomitant use of XELODA 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 XELODA is used concomitantly with nephrotoxic drugs (e.g. platinum salts, irinotecan, methotrexate, intravenous bisphosphonates).

The efficacy of XELODA for the adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen was derived from a study in the published literature. XELODA was evaluated in ESPAC-4 trial, a two-group, open-label, multicenter, randomized trial, where the major efficacy outcome measure was overall survival.

The exposure of capecitabine increases in patients with mild to moderate hepatic impairment. The effect of severe hepatic impairment on the safety and pharmacokinetics of XELODA is unknown [see Clinical Pharmacology (12.3)]. Monitor patients with hepatic impairment more frequently for adverse reactions.

XELODA (capecitabine) is a nucleoside metabolic inhibitor indicated for:

Colorectal Cancer

• adjuvant treatment of patients with Stage III colon cancer as a single agent or as a component of a combination chemotherapy regimen. (1.1)
• perioperative treatment of adults with locally advanced rectal cancer as a component of chemoradiotherapy. (1.1)
• treatment of patients with unresectable or metastatic colorectal cancer as a single agent or as a component of a combination chemotherapy regimen. (1.1)

Breast Cancer

• treatment of patients with advanced or metastatic breast cancer as a single agent if an anthracycline- or taxane-containing chemotherapy is not indicated. (1.2)
• treatment of patients with advanced or metastatic breast cancer in combination with docetaxel after disease progression on prior anthracycline-containing chemotherapy. (1.2)

Gastric, Esophageal, or Gastroesophageal Junction Cancer

• treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen. (1.3)
• treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen. (1.3)

Pancreatic Cancer

• adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen. (1.4)

Hyperbilirubinemia can occur with XELODA. In the 875 patients with metastatic breast or colorectal cancer who received XELODA 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 XELODA 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 XELODA. 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 received XELODA with docetaxel, grade 3 hyperbilirubinemia occurred in 7% and grade 4 hyperbilirubinemia occurred in 2%.

Withhold XELODA 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)].

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, N^5-10-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.

• Cardiotoxicity: May be more common in patients with a prior history of coronary artery disease. Withhold XELODA for cardiotoxicity as appropriate. The safety of resumption of XELODA in patients with cardiotoxicity that has resolved has not been established. (2.5, 5.3)
• Diarrhea: Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.4)
• Dehydration: Optimize hydration before starting XELODA. Monitor hydration status and kidney function at baseline and as clinically indicated. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.5)
• Renal Toxicity: Monitor renal function at baseline and as clinically indicated. Optimize hydration before starting XELODA. Withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.6)
• Serious Skin Toxicities: Monitor for new or worsening serious skin reactions. Permanently discontinue XELODA in patients who experience a severe cutaneous adverse reaction. (5.7)
• Palmar-Plantar Erythrodysesthesia Syndrome: Withhold XELODA then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. (2.5, 5.8)
• Myelosuppression: Monitor complete blood count at baseline and before each cycle. XELODA is not recommended in patients with baseline neutrophil counts <1.5 × 10⁹/L or platelet counts <100 × 10⁹/L. For grade 3 or 4 myelosuppression, withhold XELODA and then resume at same or reduced dose, or permanently discontinue, based on occurrence. (2.5, 5.9)
• Hyperbilirubinemia: Patients with Grade 3-4 hyperbilirubinemia may resume treatment once the event is Grade 2 or less (≤3 × ULN), using the percent of current dose as shown in column 3 of Table 1 (2.5, 5.10)
• Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. (5.11, 8.1, 8.3)

Based on findings from animal reproduction studies and its mechanism of action, XELODA can cause fetal harm when administered to a pregnant woman. Insufficient data is available on XELODA 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 XELODA and for 6 months following the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with XELODA and for 3 months following the last dose [see Use in Specific Populations (8.1, 8.3)].

Refer to Sections 2.5 and 2.6 for information related to dosage modifications for adverse reactions and renal impairment (2.5 and 2.6).

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

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

Tablets, film-coated:

• 150 mg: biconvex, oblong, light-peach colored, with "XELODA" on one side and "150" on the other
• 500 mg: biconvex, oblong, peach colored, with "XELODA on one side and "500" on the other

The following adverse reactions have been identified during post-approval use of XELODA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Eye: lacrimal duct stenosis, corneal disorders including keratitis

Hepatobiliary: hepatic failure

Immune System Disorders: angioedema

Nervous System: toxic leukoencephalopathy

Renal & Urinary: acute renal failure secondary to dehydration including fatal outcome

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

• Lactation: Advise not to breastfeed. (8.2)
• Hepatic Impairment: Monitor patients with hepatic impairment more frequently for adverse reactions. (8.7)

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.

Advise the patient to read the FDA-approved patient labeling (Patient Information).

XELODA (capecitabine) tablets are supplied as follows:

• 150 mg, biconvex, oblong, film-coated, light peach tablets with "XELODA" on one side and "150" on the other; available in bottles of 60 tablets (NDC 61269-470-60), individually packaged in a carton.

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.

XELODA is indicated for the:

• treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen.
• treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen.

The efficacy of XELODA for treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen was derived from studies in the published literature. XELODA was evaluated in REAL-2, a randomized non-inferiority, 2×2 factorial trial, where the major efficacy outcome measure was overall survival, and an additional randomized trial conducted by the North Central Cancer Treatment Group, where the major efficacy outcome measure was objective response rate.

The efficacy of XELODA for the treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen was derived from studies in the published literature. XELODA was evaluated in the ToGA trial [NCT01041404], an open-label, multicenter, randomized trial where the primary efficacy measure was overall survival.

Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking XELODA 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 XELODA was introduced. These events occurred within several days and up to several months after initiating XELODA and, in a few cases, within 1 month after stopping XELODA. 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)].

The recommended dosage of XELODA for unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer is:

• 625 mg/m² orally twice daily on days 1 to 21 of each 21-day cycle for a maximum of 8 cycles in combination with platinum-containing chemotherapy.
  
  OR
• 850 mg/m² or 1,000 mg/m² orally twice daily for the first 14 days of each 21-day cycle until disease progression or unacceptable toxicity in combination with oxaliplatin 130 mg/m² administered intravenously on day 1 of each cycle. Individualize the dose and dosing schedule of XELODA based on patient risk factors and adverse reactions.

The recommended dosage of XELODA for HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma is 1,000 mg/m² orally twice daily for the first 14 days of each 21-day cycle until disease progression or unacceptable toxicity in combination with cisplatin and trastuzumab.

Refer to the Prescribing Information for agents used in combination for additional dosing information as appropriate.

In instances of exposure to crushed XELODA 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 XELODA 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 XELODA tablets.

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 XELODA (e.g., mucositis, diarrhea, neutropenia, and neurotoxicity). Patients with partial DPD activity (partial DPD deficiency) may also have increased risk of serious or fatal, adverse reactions.

Prior to initiating XELODA, test patients for genetic variants of the DPYD gene unless immediate treatment is necessary [see Clinical Pharmacology (12.5) ]. Serious adverse reactions may still occur even if no DPYD variants are identified.

Avoid use of XELODA in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency.

Withhold or permanently discontinue XELODA based on clinical assessment of the onset, duration, and severity of adverse reactions in patients with evidence of acute early-onset or unusually severe reactions. No XELODA 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. For patients with partial DPD deficiency, individualize the dosage and modify based on tolerability and intent of treatment.

An FDA-authorized test for the detection of genetic variants of the DPYD gene to identify patients at risk of serious adverse reactions with XELODA treatment 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).

Increased risk of serious adverse reactions or death in patients with complete DPD deficiency

• Test patients for genetic variants of DPYD prior to initiating XELODA unless immediate treatment is necessary. Avoid use of XELODA in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency [see 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 XELODA concomitantly with oral vitamin K antagonists, such as warfarin [see Warnings and Precautions (5.2), Drug Interactions (7.2) ].

• Clinically significant increases in prothrombin time (PT) and international normalized ratio (INR) have been reported in patients who were on stable doses of a vitamin K antagonist at the time XELODA was introduced. 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 (7.2)].
