Paclitaxel, Trastuzumab, and Pertuzumab in the Treatment of Metastatic HER2-Positive Breast Cancer

Completed · Phase 2

Conditions studied: Breast Cancer

In brief

The purpose of this study is to see if a combination of drugs can help to treat this type of cancer. One drug is a chemotherapy agent called paclitaxel (Taxol®). Paclitaxel will be given every week through the vein. Although the weekly schedule of paclitaxel is not included in the label, the schedule and dose of weekly paclitaxel have been studied and have been proven to be more effective than an old standard schedule. The other two work against HER2. One is called trastuzumab (Herceptin®) and it is commonly given to women with early HER2 positive breast cancer or with advanced HER2 positive breast cancer that has spread to other parts of the body. Trastuzumab will be given through the vein every 3 weeks (or every week at the doctor's discretion). The third drug, pertuzumab, is an investigational drug. It has not been approved by the Food and Drug Administration. It has been given in studies to over 800 people. It has been effective in treating HER2 positive breast cancer. Pertuzumab will be given every 3 weeks through the vein. This study is looking at the effectiveness of these three drugs together.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

Age ≥18
Stage IV HER2 (+) breast cancer.
Histologically documented HER2 (+) breast cancer as defined as IHC 3+ or FISH amplification of ≥ 2.0 of primary or metastatic site; results from the local lab are acceptable. (Optional tumor sample collection from primary or metastatic site may be obtained for HER2 testing at MSKCC).
ECOG performance 0 -1 (Appendix A)
0-1 prior treatment in the metastatic setting (ie: hormone, chemotherapy, biologic, targeted agents). Prior anthracycline, paclitaxel, and trastuzumab in the adjuvant setting are allowed. If the patient has one trastuzumab-based treatment in the metastatic setting and is given a break (even intermittently) from the partner drug given with trastuzumab and is continued on trastuzumab alone, this would still be considered as one treatment. For example, if the patient was given paclitaxel + trastuzumab and was later continued on trastuzumab alone or then restarted on paclitaxel + trastuzumab (at the physician's discretion for any reason), the regimen paclitaxel + trastuzumab followed by trastuzumab alone (or followed by paclitaxel + trastuzumab again) may be considered as one treatment.
Measurable or non-measurable disease. Measurable lesions are defined as those that can be measured accurately in at least one diameter, that is 20 mm using conventional imaging techniques (including incremental CT) or 10 mm using spiral CT equipment and a lymph node 15 mm along the short axis. Non-measurable lesions are all other lesions, including small lesions (longest diameter <10mm pathological a lymph nodes with 10 to less than 15mm along the short axis, bony metastases, leptomeningeal disease, ascites, pleural/pericardial effusions, inflammatory breast cancer, lymphangitis carcinomatosis, and heavily calcified and cystic/necrotic lesions.
LVEF ≥ 50%
Hematologic parameters: white blood cell (WBC) count of ≥ 3000/ul, absolute neutrophil count (ANC) ≥1500/ul, platelets ≥ 100,000/ul, hemoglobin ≥ 10.0 g/dl
Non-hematologic parameters: bilirubin ≤ 1.5 mg/dl, AST/ALT ≤ 2.5 x upper limit of normal (ULN), alkaline phosphatase ≤ 5 x ULN.
Creatinine ≤ 1.5 mg/dl
Patients with stable and treated brain lesions of a duration of ≥ 2 months may be enrolled.

You may not qualify if…

History of prior cardiac morbidities within 12 months (unstable angina, myocardial infarction, CHF, uncontrolled ventricular arrhythmias)
Prior pertuzumab
History of prior ≥ G 3 hypersensitivity (HSR) or any toxicity to trastuzumab that warranted permanent cessation of this antibody
History of prior ≥ G 3 HSR or any toxicity to paclitaxel warranted permanent cessation of this chemotherapy
> G 2 peripheral neuropathy
Patients with a history of chronic hepatitis B or C should be excluded from the study as paclitaxel is potentially hepatotoxic
Pregnant patients
