Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of capecitabine tablets as a single agent was evaluated in patients with Stage III colon cancer in X-ACT [see Clinical Studies (14.1)]. Patients receivedcapecitabine tablets 1,250 mg/m2 orally twice daily for the first 14 days of a 21-day cycle (N=995) or leucovorin 20 mg/m2 intravenously followed by fluorouracil 425 mg/m2 as an intravenous bolus on days 1 to 5 of each 28-day cycle (N=974). Among patients who received capecitabine tablets, the median duration of treatment was 5.4 months.
Deaths due to all causes occurred in 0.8% of patients who received capecitabine tablets on study or within 28 days of receiving study drug. Permanent discontinuation due to an adverse reaction occurred in 11% of patients who received capecitabine tablets.
Most common adverse reactions (>30%) were palmar-plantar erythrodysesthesia syndrome, diarrhea, and nausea.
