Brief Summary

This study determines the proportion of metastatic breast cancer patients progression free after 6 months when treated with gemcitabine/ cisplatin/ trastuzumab or gemcitabine/ trastuzumab.

Detailed Description

Rationale: Previous studies have demonstrated the anti-tumor efficacy of gemcitabine and trastuzumab against metastatic breast cancer when given alone and in combination. Yet, research indicates that the two drugs given together work more effectively than either alone. Laboratory studies testing the combination of trastuzumab and cisplatin have shown synergistic anti-tumor activity with the two drugs. In addition, clinical studies suggest a high level of anti-tumor activity with the combination of gemcitabine and cisplatin. Researchers are testing the triple drug combination of gemcitabine, trastuzumab, and cisplatin in the current study to evaluate the potential for enhanced responsiveness in patients with Her-2/neu overexpressing breast cancer as well as comparing it to the double drug combination of gemcitabine and trastuzumab.

Purpose: This study will measure patient responses and compare the efficacy of a double drug combination (gemcitabine and trastuzumab) with a triple drug combination (gemcitabine, trastuzumab, and cisplatin) in patients with metastatic breast cancer. Side effects will be carefully assessed in patients.

Treatment: Patients in this study will receive one of two treatment combinations. A computer will randomly assign patients to a treatment group. Group one will be given gemcitabine and trastuzumab. Gemcitabine will be given to patients on days 1 and 8, and trastuzumab on days 1, 8, and 15. Group two will receive gemcitabine, trastuzumab, and cisplatin. Gemcitabine and cisplatin will both be administered on days 1 and 8, and trastuzumab on days 1, 8, and 15. Each treatment cycle (for both groups) will last a total of 21 days. All study drugs will be administered through intravenous infusions. Several tests and exams will be given throughout the study to closely monitor patients. Thorough patient exams will be given at the beginning of each treatment cycle. Imaging tests will be done every two cycles for the first eight cycles and then every three cycles until study completion. Study treatment will be discontinued due to disease growth or unacceptable side effects.

Eligibility Criteria

Inclusion Criteria

• No evidence of congestive heart failure, symptoms of coronary artery disease, serious cardiac arrhythmias, or evidence of prior myocardial infarction on EKG or ECHO. Patients must have normal LV function and LVEF(left ventricular ejection fraction)> 50% as demonstrated by either echo or muga within the proceeding 4 weeks.
• Must have adequate renal and hepatic function documented by a serum creatinine < 1.5 x the institutional upper limit of normal (ULN), serum bilirubin <1.5 x ULN and liver enzymes (AST, ALT, or alkaline phosphatase) < 2 x ULN (< 5 x ULN if hepatic metastasis) within 21 days prior to registration.
• Patients must have an ANC (absolute neutrophil count) > 1.5, platelets > 100,000, Hemoglobin >9.0 within 21 days of registration.
• If patients are on bisphosphonates at the time of registration, with a stable creatinine over the preceding 2 months, then they may continue bisphosphonates during the study.
• No more than one prior Trastuzumab/chemotherapy or Trastuzumab/biotherapy combination for metastatic disease. Additional Trastuzumab therapy may have been given in the adjuvant setting. Prior hormonal therapy is allowed for either adjuvant or metastatic disease.
• Must be >3 weeks since administration of last chemotherapy prior to initiation of treatment on this trial. Prior trastuzumab may have been administered within one week of initiation of treatment on this trial if the last dose was 2 mg/kg. Any prior trastuzumab dosing greater than 2 mg/kg requires a 3 week washout period.
• Patients may have received prior cisplatin or carboplatin for metastatic disease.
• No CNS(central nervous system)metastasis disease.
• No active infection at time of registration.
• Pregnant or nursing women may not participate in trial.
• Patients must be informed of the investigational nature of this study and sign and give written informed consent in accordance with institutional and federal guidelines.
• ECOG (Eastern Cooperative Oncology Group)performance status < 2 at the time of registration.
• Patients may participate in a non-treatment related protocol while participating in this study.
• No other active malignancy is allowed. Adequately treated basal cell, squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease-free for 5 years is allowed.
