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.
Adjuvant Treatment of Colon Cancer
Single Agent
The safety of capecitabine as a single agent was evaluated in patients with Stage III colon cancer in X-ACT [see Clinical Studies (14.1)] . Patients received capecitabine 1,250 mg/m 2orally twice daily for the first 14 days of a 21-day cycle (N=995) or leucovorin 20 mg/m 2intravenously followed by fluorouracil 425 mg/m 2as an intravenous bolus on days 1 to 5 of each 28-day cycle (N=974). Among patients who received capecitabine, the median duration of treatment was 5.4 months.
Deaths due to all causes occurred in 0.8% of patients who received capecitabine 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.
Most common adverse reactions (>30%) were palmar-plantar erythrodysesthesia syndrome, diarrhea, and nausea.
Tables 2 and 3 summarize the adverse reactions and laboratory abnormalities in X-ACT.
