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.

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.

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.

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.

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

Lumpectomy or Mastectomy with Sentinel Node or Axillary Node Dissection

The purpose of this research study is to compare the effectiveness and safety of ABP 980 against trastuzumab in women with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer.

Efficacy and Safety Study of ABP 980 Compared With Trastuzumab in Women With HER2-positive Early Breast Cancer

A Randomized, Double-Blind, Phase 3 Study Evaluating the Efficacy and Safety of ABP 980 Compared With Trastuzumab in Subjects With HER2 Positive Early Breast Cancer

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.

Participants received ABP 980 at an initial dose of 8 mg/kg over a 90-minute 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.

Neoadjuvant Phase: ABP 980

Participants received trastuzumab at an initial dose of 8 mg/kg over a 90-minute IV infusion, then 6 mg/kg IV infusion Q3W for 3 additional cycles plus 175 mg/m² paclitaxel Q3W for 4 cycles.

Neoadjuvant Phase: Trastuzumab

After surgery, participants initially randomized to ABP 980 continued to receive ABP 980 at a dose of 6 mg/kg IV infusion Q3W for up to 1 year from the first day of study drug administration in the neoadjuvant phase.

Adjuvant Phase: ABP 980/ABP 980

After surgery, participants originally randomized to trastuzumab were re-randomized and continued to receive trastuzumab at a dose of 6 mg/kg IV infusion Q3W for up to 1 year from the first day of study drug administration in the neoadjuvant phase.

Adjuvant Phase: Trastuzumab/Trastuzumab

After surgery, participants originally randomized to trastuzumab were re-randomized and switched to receive ABP 980 at a dose of 6 mg/kg IV infusion Q3W for up to 1 year from the first day of study drug administration in the neoadjuvant phase.

In the Tumor Node Metastasis (TNM) staging system, a "T" followed by a number shows the size of the tumor. Less than T4 indicates a tumor that is 5 cm or less. T4 indicates the tumor is any size, but has spread beyond the breast tissue to the chest wall and/or skin.

Study Director

The clinical equivalence between ABP 980 and trastuzumab was first evaluated by comparing the 2-sided 90% confidence interval (CI) of the Risk Difference (RD; ABP 980 - Trastuzumab) of pCR between ABP 980 and trastuzumab with a fixed margin of (-13%, 13%), estimated using a generalized linear model adjusted for stratification factors tumor (T)-stage, nodal status, hormone receptor status, planned paclitaxel dosing schedule, and geographic region.

If the test of equivalence on the RD of pCR was successful, then equivalence was tested on the Risk Ratio (RR; ABP 980 / Trastuzumab) of pCR at a 2-sided significance level of 0.05 by comparing the 2-sided 90% CI of the RR of pCR between ABP 980 and trastuzumab, estimated using a generalized linear model adjusted for stratification factors: tumor (T)-stage, nodal status, hormone receptor status, planned paclitaxel dosing schedule, and geographic region.

The pCR evaluable population, which included all randomized participants who received any amount of study drug, underwent the surgery, and had a non-missing evaluable pCR assessment from the local laboratory evaluation.
