An FDA-authorized test for the detection of the DPYD gene to identify patients at risk of serious adverse reactions with capecitabine tablets are 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 capecitabine tablets in patients known to have certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency. No capecitabine tablets 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 )]. 2.2 Recommended Dosage for Colorectal Cancer Adjuvant Treatment of Colon Cancer Single Agent The recommended dosage of capecitabine tablets is 1,250 mg/m 2 orally twice daily for the first 14 days of each 21-day cycle for a maximum of 8 cycles.

Refer to the Prescribing Information for oxaliplatin for additional dosing information as appropriate. 2.3 Recommended Dosage for Breast Cancer Advanced or Metastatic Breast Cancer Single Agent The recommended dosage of capecitabine tablets is 1,000 mg/m 2 or 1,250 mg/m 2 orally twice daily for the first 14 days of a 21-day cycle until disease progression or unacceptable toxicity. Individualize the dose and dosing schedule of capecitabine tablets based on patient risk factors and adverse reactions. In Combination with Docetaxel The recommended dosage of capecitabine tablets is 1,000 mg/m 2 or 1,250 mg/m 2 orally twice daily for the first 14 days of a 21-day cycle until disease progression or unacceptable toxicity in combination with docetaxel 75 mg/m 2 administered intravenously on day 1 of each cycle.

Individualize the dose and dosing schedule of capecitabine tablets based on patient risk factors and adverse reactions. The recommended dosage of capecitabine tablets for HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma is 1,000 mg/m 2 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. 2.5 Recommended Dosage for Pancreatic Cancer The recommended dosage of capecitabine tablets is 830 mg/m 2 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/m 2 administered intravenously on days 1, 8, and 15 of each cycle. Refer to Prescribing Information for gemcitabine for additional dosing information as appropriate. 2.6 Dosage Modifications for Adverse Reactions Monitor patients for adverse reactions and modify dosages of capecitabine tablets as described in Table 1. Do not replace missed doses of capecitabine tablets; instead resume capecitabine tablets with the next planned dosage. When capecitabine tablets is administered with docetaxel, withhold capecitabine tablets and docetaxel until the requirements for resuming both capecitabine tablets and docetaxel are met. Refer to the Prescribing Information for docetaxel for additional dosing information as appropriate. Table 1 Recommended Dosage Modifications for Adverse Reactions Severity Dosage Modification Resume at Sameor Reduced Dose (Percentof Current Dose) Grade 2 1st appearance Withhold until resolved to grade 0-1. 100% 2nd appearance 75% 3rd appearance 50% 4th appearance Permanently discontinue. - Grade 3 1st appearance Withholduntil resolved to grade 0-1. 75% 2nd appearance 50% 3rd appearance Permanently discontinue. - Grade 4 1st appearance Permanently discontinue OR Withhold until resolved to grade 0-1. 50% Hyperbilirubinemia Patients with Grade 3-4 hyperbilirubinemia may resume treatment once the event is Grade 2 or less (less than three times the upper limit of normal), using the percent of current dose as shown in column 3 of Table 1 [see Warnings and Precautions ( 5.10 )]. 2.7 Dosage Modification For Renal Impairment Reduce the dose of capecitabine tablets 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) ]. 2.8 Administration Round the recommended dosage for patients to the nearest 150 mg dose to provide whole capecitabine tablets. Swallow capecitabine tablets whole with water within 30 minutes after a meal. Do not chew, cut, or crush capecitabine tablets [see Warnings and Precautions ( 5.12 )]. Take capecitabine tablets 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. Capecitabine tablet is a hazardous drug. Follow applicable special handling and disposal procedures.

8.4 Pediatric Use The safety and effectiveness of capecitabine tablets 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 capecitabine tablets 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%).
