简要总结
RATIONALE: Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining gefitinib and trastuzumab with docetaxel may kill more tumor cells.
PURPOSE: This phase I/II trial is studying the best dose of docetaxel when given together with gefitinib and trastuzumab in treating patients with metastatic breast cancer.
详细描述
OBJECTIVES:
Primary
- Determine the safety and efficacy of gefitinib, trastuzumab (Herceptin®), and docetaxel, in terms of time to disease progression, in patients with HER2/neu-overexpressing metastatic adenocarcinoma of the breast.
Secondary
- Determine the objective tumor response rate in patients treated with this regimen.
- Correlate expression and/or degree of phosphorylation of epidermal growth factor receptor, HER2/neu, c-fos, Akt, ERK½, P13K, p53, p21, and p27 with outcome in patients treated with this regimen.

结局指标
主要结局
Number of Participants With at Least One Dose Limiting Toxicity in Phase I
时间窗: 4 weeks from start of treatment, up to 2 years
Dose Limiting Toxicity (DLT) defined as any treatment-related grade 3 or greater except for hematological toxicities which must be grade 4. Interstitial Lung Disease (ILD) related to treatment should be considered as a DLT regardless of the grade.
Recommended Phase II Dose
时间窗: 4 weeks from start of treatment, up to 2 years
The maximum tolerated dose (MTD): subjects received gefitinib 250 mg orally daily, trastuzumab 6 mg/kg intravenously every 3 weeks (after an initial dose of 8 mg/kg with cycle 1), and docetaxel 75 mg/m\^2 intravenously every 3 weeks. This was to serve as the phase II dose if no dose-limiting toxicities (DLTs) occurred in the first three subjects. If one DLT occurred in the first three subjects, another three subjects where to be enrolled at this dose, whereas if two DLTs occurred in the first three subjects, the docetaxel dose was to be decreased to 60 mg/m\^2. The study would then be continued only if no more than one patient had a DLT at this dose. Once the dose of docetaxel was established, all further subjects were to be treated at the phase II MTD dose.
次要结局
- Progression-free Survival(Until disease progression, up to 5 years.)
- Objective Response Rate(After 3 cycles of treatment, up to 2 years.)
- Overall Survival(Until death from any cause, up to 5 years.)
