Drug Information available for: Trastuzumab

Arm Intervention/treatment
Experimental: ABP 980

Participants received ABP 980 at an initial dose of 8 mg/kg by intravenous (IV) infusion, then 6 mg/kg IV infusion every 3 weeks (Q3W) for 3 additional cycles plus 175 mg/m² paclitaxel Q3W for 4 cycles during the neoadjuvant phase.

Surgery (lumpectomy or mastectomy with sentinel lymph node dissection or axillary lymph node dissection) was completed 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase.

After surgery (adjuvant phase) participants continued receiving 6 mg/kg ABP 980 IV Q3W for up to 1 year from the first day of study drug administration in the neoadjuvant phase.

Drug: ABP 980
ABP 980 was administered at an initial dose of 8 mg/kg over a 90-minute intravenous (IV) infusion, then 6 mg/kg IV infusion Q3W for all subsequent cycles.

Drug: Paclitaxel
Paclitaxel, 175 mg/m² Q3W for 4 cycles (or 80 mg/m² QW for 12 cycles, if local standard of care).

Procedure: Lumpectomy or Mastectomy with Sentinel Node or Axillary Node Dissection
Active Comparator: Trastuzumab

Participants received trastuzumab at an initial dose of 8 mg/kg IV infusion, then 6 mg/kg IV infusion Q3W for 3 additional cycles plus 175 mg/m² paclitaxel Q3W for 4 cycles during the neoadjuvant phase.

Surgery (lumpectomy or mastectomy with sentinel lymph node dissection or axillary lymph node dissection) was completed 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase.

After surgery (adjuvant phase) participants were re-randomized to either continue receiving 6 mg/kg trastuzumab IV Q3W or transition to 6 mg/kg ABP 980 IV Q3W for up to 1 year from the first day of study drug administration in the neoadjuvant phase.

Drug: Trastuzumab
Trastuzumab was administered at an initial dose of 8 mg/kg over a 90-minute IV infusion, then 6 mg/kg IV infusion Q3W for all subsequent cycles.
Other Name: Herceptin®

Drug: Paclitaxel
Paclitaxel, 175 mg/m² Q3W for 4 cycles (or 80 mg/m² QW for 12 cycles, if local standard of care).

Procedure: Lumpectomy or Mastectomy with Sentinel Node or Axillary Node Dissection



Primary Outcome Measures :
  1. Percentage of Participants With a Pathologic Complete Response [ Time Frame: 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase ]

    Pathologic complete response (pCR) was defined as the absence of invasive tumor cells in the breast tissue and in axillary lymph nodes, regardless of residual ductal carcinoma in situ (DCIS).

    Participants underwent a lumpectomy or mastectomy with sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND) within 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase. The pathology evaluation of surgical specimens for pCR analysis was conducted by local laboratories at the study sites.



Secondary Outcome Measures :
  1. Percentage of Participants With a Pathologic Complete Response in Breast Tissue Only [ Time Frame: 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase ]

    Pathologic complete response (pCR) was defined as the absence of invasive tumor cells in the breast tissue, regardless of residual ductal carcinoma in situ (DCIS).

    Participants underwent a lumpectomy or mastectomy with sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND) within 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase. The pathology evaluation of surgical specimens for pCR analysis was conducted by local laboratories at the study sites.


  2. Percentage of Participants With a Pathologic Complete Response in Breast Tissue and Axillary Lymph Nodes and Absence of DCIS [ Time Frame: 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase ]

    Pathological complete response was defined as the absence of invasive tumor cells in the breast tissue and axillary lymph node(s) and absence of residual DCIS.

    Participants underwent a lumpectomy or mastectomy with sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND) within 3 to 7 weeks after the last dose of study drug in the neoadjuvant phase. The pathology evaluation of surgical specimens for pCR analysis was conducted by local laboratories at the study sites.
