6.1 Clinical Trial Experience in Breast Cancer 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 clinical practice.

The safety data below were collected from 1492 women who received doxorubicin at a dose of 60 mg/m 2 and cyclophosphamide at a dose of 600 mg/m 2 (AC) every 3 weeks for 4 cycles for the adjuvant treatment of axillary lymph node positive breast cancer.

The median number of cycles received was 4.

Selected adverse reactions reported in this study are provided in Table 1.

No treatment-related deaths were reported in patients on either arm of the study.

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.
