Weekly Gemcitabine and Trastuzumab in the Treatment of Patients With Human Epidermal Growth Factor Receptor 2 (HER2) Positive Metastatic Breast Cancer
Due to its remarkable activity as salvage treatment in women with metastatic breast cancer as well as the additive activity observed for gemcitabine administered in combination with trastuzumab, the clinical activity of the combination of gemcitabine administered with trastuzumab represents an exciting and ideal combination to further evaluate in Her 2 over-expressing metastatic breast cancer patients.

|Official Title:||Phase II Trial of Weekly Gemcitabine and Herceptin in the Treatment of Patients With HER-2 Overexpressing Metastatic Breast Cancer|
- Overall Response Rate (ORR) [ Time Frame: 18 Months ] [ Designated as safety issue: No ]The Percentage of Patients Who Experience an Objective Benefit From Treatment. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
- Progression Free Survival (PFS) [ Time Frame: 21 Months ] [ Designated as safety issue: No ]The Length of Time, in Months, That Patients Were Alive From Their First Date of Protocol Treatment Until Worsening of Their Disease. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
- Overall Survival (OS) [ Time Frame: 24 months ] [ Designated as safety issue: No ]The Length of Time, in Months, That Patients Were Alive From Their First Date of Protocol Treatment Until Death

All patients entering this trial received treatment with a combination of gemcitabine and trastuzumab. Gemcitabine 1000 mg/m2 was administered intravenously on days 1, 8,and 15 of a 28-day cycle. Trastuzumab was administered as a 4 mg/kg intravenous loading dose on day 1 and subsequently at a dose of 2 mg/kg on a weekly basis.
