研究组 & 干预措施
Group A
Subjects in Treatment Group A (in cohorts of three) will receive oral lapatinib QD (Days 1 to 28). Following lapatinib administration on Day 1, paclitaxel will be administered intravenously over one hour followed immediately by an IV infusion of carboplatin over not less than 15 minutes. Carboplatin will be followed by an initial loading dose of trastuzumab by 90 minute IV infusion (first dose only) with subsequent IV doses of trastuzumab to be given weekly over 30 minute infusion. Doses of paclitaxel and carboplatin will be administered weekly (Day 1, 8, and 15). Trastuzumab is administered on Day 1, 8, 15, and 22. Treatment cycles are repeated every four weeks.

Group B
Subjects in Treatment Group B (in cohorts of three) will receive oral lapatinib QD (Days 1 to 28).

结局指标
主要结局
Adverse events and safety evaluations
时间窗: 28 days
* The OTR for Treatment Group A (lapatinib, paclitaxel, carboplatin, and trastuzumab) will be defined as the maximum dose level at which no more than one subject out of six experiences a dose-limiting toxicity (DLT) after completing one treatment cycle. * The OTR for Treatment Group B (lapatinib, paclitaxel, carboplatin) will be defined as the maximum dose level at which no more than one subject out of six experiences a DLT after completing one treatment cycle. * Adverse events and changes from baseline in laboratory values, Multiple-gated Acquisition (MUGA) scanning/Echocardiogram (ECHO), and vital signs will be evaluated to assess safety and tolerability.
次要结局

- Duration of Response (DOR)(From date of randomization until the date of first documented progression or death from any cause,whichever came first, assessed up to 48.5 months)
- Progression-free survival (PFS)(From date of randomization until the date of first documented progression or death from any cause,whichever came first, assessed up to 48.5 months)
