In Combination with Docetaxel
The safety of Capecitabine in combination with docetaxel was evaluated in patients with metastatic breast cancer in Study SO14999
[see
Clinical Studies (14.2)].
Patients received Capecitabine 1,250 mg/m
2orally twice daily for the first 14 days of a 21-day cycle with docetaxel 75 mg/m
2as 1-hour intravenous infusion on day 1 of each 21-day cycle for at least 6 weeks or docetaxel 100 mg/m
2as a 1-hour intravenous infusion on day 1 of each 21-day cycle for at least 6 weeks. Among patients who received Capecitabine, the mean duration of treatment was 4.2 months.
Permanent discontinuation due to an adverse reaction occurred in 26% of patients who received Capecitabine. Dosage interruptions due to an adverse reaction occurred in 79% of patients who received Capecitabine and dosage reductions due to an adverse reaction occurred in 65%.
Most common adverse reactions (>30%) were diarrhea, stomatitis, palmar-plantar erythrodysesthesia syndrome, nausea, alopecia, vomiting, edema, and abdominal pain.
Table 5summarizes the adverse reactions in Study SO14999.
