Description:
This multicenter, non-randomized, open-label, phase 2 study is designed to evaluate the
safety and efficacy of pertuzumab (Perjeta) in combination with trastuzumab (Herceptin) and
anthracycline-based chemotherapy as neoadjuvant treatment in participants with HER2-positive
locally advanced, inflammatory, or early-stage breast cancer. Each investigator will choose a
treatment regimen (A or B) for all of their participants to follow. Treatment regimen A (for
Cohort A) will include dose-dense doxorubicin and cyclophosphamide (ddAC), followed by
paclitaxel, with pertuzumab and trastuzumab given from the start of paclitaxel. Treatment
regimen B (for Cohort B) will include 5-fluorouracil, epirubicin, and cyclophosphamide (FEC),
followed by docetaxel, with pertuzumab and trastuzumab given from the start of docetaxel.
Participants in both cohorts will subsequently undergo surgical treatment and then resume
pertuzumab and trastuzumab treatment.

Primary Outcome Measures
Measure: | Percentage of Participants With New York Heart Association (NYHA) Class III and IV Heart Failure During the Neoadjuvant Treatment Period |
Time Frame: | Baseline to 24 weeks |
Safety Issue: | |
Description: | Symptomatic left ventricular systolic dysfunction (LVSD) is defined as heart failure. NYHA classifies participants' heart failure condition based on the participant's symptoms. Class III: marked limitation of the physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. Class IV: Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases. 95 percent (%) confidence intervals (CIs) are calculated with the use of the Clopper-Pearson method. |
Secondary Outcome Measures
Measure: | Percentage of Participants With NYHA Class III and IV Heart Failure During the Adjuvant Treatment Period at Primary Completion Date (03 March 2016) |
Time Frame: | Cycle 9 to Cycle 21 (cycle length=3 weeks; up to approximately 8 months) up to clinical cut-off date, 03 March 2016 (Month 20) |
Safety Issue: | |

Time Frame: | 24 weeks after neoadjuvant therapy (Post 8 cycles of neo-adjuvant therapy [cycle length=2¬3 weeks]) |
Safety Issue: | |
Description: | tpCR is defined as the absence of any residual invasive cancer in the breast and the absence of any metastatic cells in the regional lymph nodes. |
Measure: | Percentage of Participants With Clinical Response as Determined by the Investigator According to Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 During the Neoadjuvant Treatment Period |
Time Frame: | Baseline until disease progression or death due to any cause up to 24 weeks (assessed on Day 1 of Cycles 1-8 [cycle length=2-3 weeks]) |
Safety Issue: | |
Description: | Clinical response was classified as either complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD). CR: disappearance of all target lesions; PR: at least a 30% decrease in the sum of the longest diameter compared to Baseline. SD: neither sufficient shrinkage to qualify for PR nor sufficient (20%) increase to qualify for disease progression, in addition to no new target lesions. PD: at least a 20% increase in the sum of the longest diameter, taking as reference the smallest sum of the longest diameter observed at previous tumor assessment, or the appearance of any new lesions. 95% CIs are calculated with the use of the Clopper-Pearson method. |

Time Frame: | Baseline until disease progression or death due to any cause up to approximately 6.5 years (assessed on Day 1 of Cycles 1-8 [cycle length=2-3 weeks] and every 3 months thereafter until study completion or early termination) |
Safety Issue: | |
Description: | EFS is defined as the time from enrollment to the first occurrence of progressive disease, relapse, or death from any cause. PD: at least a 20% increase in the sum of the longest diameter, taking as reference the smallest sum of the longest diameter observed at previous tumor assessment, or the appearance of any new lesions. |

Safety Issue: | |
Description: | iDFS is defined as the time from the first date of no disease (the date of surgery) to the first documentation of progressive invasive disease, relapse, or death. PD: at least a 20% increase in the sum of the longest diameter, taking as reference the smallest sum of the longest diameter observed at previous tumor assessment, or the appearance of any new lesions. |
