What was measured

Distant disease-free survival (DDFS) is defined as the time from randomization to the date of distant breast cancer recurrence (i.e., evidence of breast cancer in any anatomic site other than for ipsilateral \[loco-regional\] invasive breast cancer recurrence that has either been histologically confirmed or clinically diagnosed as recurrent invasive breast cancer).

Groups in this outcome

All Participants

In the Treatment Cross-Over Period of the study, all participants received their first 6 cycles of treatment in accordance with the study arm to which they were randomized: Arm A) pertuzumab IV and trastuzumab IV (P+H IV) for 3 treatment cycles followed by the pertuzumab and trastuzumab fixed-dose combination for subcutaneous administration (PH FDC SC) for 3 treatment cycles (1 cycle = 21 days); or Arm B) PH FDC SC for 3 treatment cycles followed by P+H IV for 3 treatment cycles (1 cycle = 21 days). Following completion of this study period, participants chose one of the two study treatments to receive in the Treatment Continuation Period for the remaining anti-HER2 treatment cycles (18 planned cycles in total, including pre-study neoadjuvant treatment). After completing study treatment, participants entered the Follow-up Period wherein they were to be followed for 3 years from the date the last participant was randomized.

A: P+H IV Followed by PH FDC SC

In the Treatment Cross-Over Period of the study, participants randomized to Arm A first received pertuzumab IV and trastuzumab IV (P+H IV) administration for 3 treatment cycles followed by the pertuzumab and trastuzumab fixed-dose combination for subcutaneous administration (PH FDC SC) for 3 treatment cycles (1 cycle = 21 days). Following completion of this study period, participants chose one of the two study treatments to receive in the Treatment Continuation Period for the remaining anti-HER2 treatment cycles (18 planned cycles in total, including pre-study neoadjuvant treatment). After completing study treatment, participants entered the Follow-up Period wherein they were to be followed for 3 years from the date the last participant was randomized.

B: PH FDC SC Followed by P+H IV

In the Treatment Cross-Over Period of the study, participants randomized to Arm B first received the pertuzumab and trastuzumab fixed-dose combination for subcutaneous administration (PH FDC SC) for 3 treatment cycles followed by pertuzumab intravenous (IV) and trastuzumab IV (P+H IV) administration for 3 treatment cycles (1 cycle = 21 days). Following completion of this study period, participants chose one of the two study treatments to receive in the Treatment Continuation Period for the remaining anti-HER2 treatment cycles (18 planned cycles in total, including pre-study neoadjuvant treatment). After completing study treatment, participants entered the Follow-up Period wherein they were to be followed for 3 years from the date the last participant was randomized.
