- Registration Number
- NCT01998906
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This study will assess the efficacy and safety of adding Herceptin to a paclitaxel-containing regimen followed by cyclophosphamide/methotrexate/fluorouracil (CMF) chemotherapy in women with locally advanced breast cancer and HER2/c-erbB-2 gene amplification. In a parallel observational study patients with HER2-negative disease will receive the same chemotherapy without Herceptin.

Percentage of Participants Achieving Either Complete Response (CR) or Partial Response (PR) According to Modified Response Evaluation Criteria in Solid Tumors (RECIST) Criteria BL, Presurgery: Day 1 of Cycles 1-10 Assessments were made based on objective tumor measurements of the lesions as recorded in the case report form. In inflammatory cancer, progressive disease (PD) was defined as progression of any of the 2 signs of breast edema and erythema. In non-inflammatory cancer, PD was concluded if either the investigator judged the participant as having progressed at any time prior to surgery, or there was at least a 20% increase in the sum of target lesions (TLs), any new lesion, or clear progression of any nontarget lesion (NTLs). Clear progression of any NTL was defined as at least a 20% increase in the sum of NTLs compared to BL. PR was defined as at least a 30% decrease from BL in the sum of the longest diameter of TLs. CR was defined as no PD as assessed by the investigator and complete disappearance of all lesions.

Overall Survival (OS) - Percentage of Participants With an Event BL, Presurgery: Day 1 (Cycles 1-7) and Days 1 and 8 (Cycles 8-10); Postsurgery: Day 1 (Cycles 1-17); every 6 months up to 60 months after last dose of study drug; yearly thereafter OS was defined as the time from the date of randomization to the date of the death due to any cause.
