Phase 2 Trial of Pertuzumab and Trastuzumab With Weekly Paclitaxel and Chemotherapy for HER2 Positive Breast Cancer
- Conditions
- Her2-Positive Breast Cancer
- Interventions
- Registration Number
- NCT01855828
- Lead Sponsor
- Yale University
- Brief Summary
The main goal of this clinical trial is to test if adding pertuzumab (Perjeta), improves the anticancer activity of the combination chemotherapy regimen of trastuzumab (Herceptin) concomitant with paclitaxel, 5-fluorouracil, epirubicin, and cyclophosphamide (T-FEC). The study will also test the safety of this therapy.
- Detailed Description
Subjects will receive 6 months of T-FEC chemotherapy concomitant with trastuzumab and pertuzumab before surgery. Subsequently, subjects will undergo surgery to remove any cancer from the breast and axillary lymph nodes that may have survived the chemotherapy. It is expected that the majority of women will have no viable cancer left in the breast or lymph nodes by the time all chemotherapy is completed.

- Target Recruitment
- 50
- Patients with histologically confirmed stage I-III, HER2-positive invasive breast cancer for which adjuvant/neoadjuvant chemotherapy is indicated based on physician judgment following NCCN practice guidelines.
HER2 overexpression or amplification will be based on local test results and is defined as either:
(i) IHC staining of 3+ (uniform, intense membrane staining) in greater than or equal to 10% of invasive tumor cells or, (ii) Fluorescent in situ hybridization (FISH) result of more than six HER2 gene copies per nucleus or, (iii) FISH ratio (HER2 gene signals to chromosome 17 signals) of greater than or equal to 2.0.
- Patients with synchronous bilateral breast cancers are eligible if at least one of the tumors is HER2-positive.
- Left Ventricular Ejection Fraction (LVEF) greater or equal to 50% at baseline as determined by either ECHO or MUGA, or within the institution's normal limits.
- Women of childbearing potential must have a negative pregnancy test (serum or urine beta HCG) prior to initiation of chemotherapy. Both female and male breast cancer patients who are sexually active have to agree to practice contraception while participating in the trial and for 3 month after completion of therapy.
- Adequate bone marrow function as indicated by the following:
- ANC greater than or equal to 1500/uL
- Platelets greater than or equal to 100,000/uL
- Hemoglobin greater than or equal to 10 g/dL
- Adequate renal function, as indicated by creatinine less than or equal to 1.5 times upper limit of normal (ULN)
- Adequate liver function, as indicated by bilirubin less than or equal to 1.5 X ULN and AST or ALT less than or equal to 2x ULN.
- Signed informed consent.
Patients will be excluded from the study based on any of the following criteria:
- Patients who underwent partial excisional biopsy, lumpectomy, segmental mastectomy, modified radical mastectomy or sentinel node biopsy and, therefore cannot be assessed for pathologic response accurately.
- Patients who are high risk for developing the following anthracycline, paclitaxel, trastuzumab or pertuzumab related toxicities including:
History of congestive heart failure, myocardial infarction or cardiomyopathy, uncontrolled hypertension despite adequate medications Pre-existing peripheral neuropathy > grade 3 Prior anthracycline therapy Known hypersensitivity to any of the study medications Patients older than age 65 due to increased risk of cardiotoxicity
- Active infection requiring systemic antibiotic therapy.
- Pregnant or lactating women

Group Intervention Description Chemo plus Pertuzumab,Trastuzumab Pertuzumab During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). Chemo plus Pertuzumab,Trastuzumab Trastuzumab During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). Chemo plus Pertuzumab,Trastuzumab 5-fluorouracil During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). Chemo plus Pertuzumab,Trastuzumab Paclitaxel During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). Chemo plus Pertuzumab,Trastuzumab Cyclophosphamide During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC). Chemo plus Pertuzumab,Trastuzumab Epirubicin During weeks 1-12, patients will receive pertuzumab, trastuzumab, and paclitaxel at the same time; during weeks 13-24 patients will receive pertuzumab and trastuzumab at the same time with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC).
- Primary Outcome Measures
Name Time Method Proportion of Participants With a Pathologic Complete Response Rate 20 weeks To estimate the pathologic complete response rate (pCR) when pertuzumab is added to weekly trastuzumab/paclitaxel followed by trastuzumab/5-fluorouracil, epirubicin and cyclophosphamide neoadjuvant chemotherapy in HER2-positive breast cancer. This study will assess pCR rates separately in ER+ and ER- cancers. Pathologic complete response is defined as no evidence of viable invasive tumor cells at the primary tumor site and axillary lymph nodes in the surgical specimen. Residual Disease (RD) is defined as: Any invasive cancer in the breast or axillary lymph nodes in the surgical specimen.
- Secondary Outcome Measures
Name Time Method Cardiac Safety Up to 1 year post surgery To assess the safety of the regimen, cardiac safety was measured by rates of clinically symptomatic congestive heart failure, asymptomatic decrease in LVEF \>10%, and decrease of LVEF below normal level. This was assessed up to 1 year following surgery.
Count of Patients With Clinical Response Up to 28 weeks To assess clinical response according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria, the number of patients are presented with a clinical response.
Residual Cancer Burden Score Up to 28 weeks To assess cancer burben, the Residual Cancer Burden (RCB) score was used. This score has a range of 0 - III, where III (3) is the worst level of burden.
