Paclitaxel is administered intravenously on days 1, 8, and 15 of each 21-day cycle Trastuzumab is administered intravenously on day 1 of each 21-day cycle Pertuzumab is administered intravenously on Day 1 of each 21-day cycle

Breast Cancer

Paclitaxel is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug

Paclitaxel

Trastuzumab works by targeting the HER2/neu receptor on cancer cells

Trastuzumab

Pertuzumab is a monoclonal antibody which targets the surface of the cells human epidermal growth factor receptor 2 protein (HER2) on the cancer cell, interfering with HER2 causing cancer cell death

DAPHNe: Paclitaxel/Trastuzumab/Pertuzumab in HER2-Positive BC

DAPHNe: De-escalation to Adjuvant Antibodies Post-pCR to Neoadjuvant THP (Paclitaxel/Trastuzumab/Pertuzumab)—a Pilot Study in HER2-positive Breast Cancer

To assess adherence to protocol-specified antibody doublet therapy in the adjuvant setting among patients with stage II-III HER2+ breast cancer who achieve pathologic complete response (pCR) following neoadjuvant Paclitaxel/Trastuzumab/Pertuzumab (THP).

To assess pathologic complete response (pCR) for 1) all patients, 2) hormone receptor positive (HR+) patients, and 3) hormone receptor negative (HR-) patients

To assess residual cancer burden (RCB) in 1) all patients, 2) hormone receptor positive patients (HR+), 3) hormone receptor negative (HR-) patients. RCB is scored from 0 to 3, (with possible values 0, 1, 2, 3), where 0 is the best score and indicates eradication of all disease at the time of surgery, and 3 is the worst score, indicating poor response to preoperative therapy.

Patients and physicians will complete questionnaires to assess reasons for off-protocol escalation (meaning, a decision to administer post-operative chemotherapy, for patients with pCR). Standardized questionnaires for both patients and physician reviewers have been developed specifically for this study. Responses are qualitative and do not involve a scale.

Patients and physicians will complete questionnaires to assess reasons for off-protocol de-escalation (meaning, a decision not to administer post-operative chemotherapy, for patients without pCR). Standardized questionnaires for both patients and physician reviewers have been developed specifically for this study. Responses are qualitative and do not involve a scale.

To assess the percentage of patients completing one year of HP

To measure event-free survival (EFS), and to compare EFS in the following subgroups: 1) Patients with pCR versus patients without pCR; 2) Patients with RCB 0 or 1, versus patients with RCB 2 or 3

To measure recurrence-free interval (RFI), and to compare RFI in the following subgroups: 1) Patients with pCR versus patients without pCR; 2) Patients with RCB 0 or 1, versus patients with RCB 2 or 3

To measure overall survival (OS) as an exploratory endpoint

To evaluate correlation between post-THP (Paclitaxel/Trastuzumab/Pertuzumab) imaging findings and pathology findings in the surgical specimen
