Brief Summary

Objectives:

Phase I part

• Primary Objective: To determine the recommended dose of the combination of lapatinib with Lipo-Dox as first line chemotherapy in patients with ErbB2 positive metastatic breast cancer.
• Secondary Objectives:To define the safety profile; To observe the response rate and progression free survival

Phase II part

• Primary Objective :To determined the objective response rate of the combination of lapatinib with Lipo-Dox as first line chemotherapy in patients with ErbB2 positive metastatic breast cancer.
• Secondary Objectives:To define the safety profile; To determined the progression free survival

Detailed Description

In phase I part Lapatinib (L) - dose level I, II 1000mg po daily dose level III, IV 1250mg po daily Intravenous Lipo Dox at the dose level reached on days 1 of a 21 days cycle• The recommended duration of combination treatment for each patient is at least 8 cycles, then, with continue combination treatment cycles or single lapatinib treatment (start with 1500 mg per day) at investigator's discretion. The treatment will stop if progressive disease, unacceptable toxicity or patient's refusal occurred. Intra patient escalation of dose level is allowed if no major toxicity noted.

In phase II part Patients will receive recommended dose according to phase I study result. The recommended duration of combination treatment for each patient is at least 8 cycles, then, with continue combination treatment cycles or single lapatinib treatment (start with 1500 mg per day) at investigator's discretion. The treatment will stop if progressive disease, unacceptable toxicity or patient's refusal occurred. Intra patient escalation of dose level is allowed if no major toxicity noted.

Eligibility Criteria

Inclusion Criteria

• In phase I part, patient may have received prior chemotherapy in metastatic setting.
• In both phase I and II part, prior Anthracyclines allowed provided total dose of doxorubicin hydrochloride ≤240 mg/m² or epirubicin ≤ 600 mg/m².
• At least 6 months since prior Anthracyclines, and 6 weeks since prior Taxane.
• Patient must be informed and well understand that in current standard of treatment, suggested first line treatments for erbB-2 positive, visceral organ metastatic breast cancer are combination of chemotherapy with herceptin.
• In phase II part, patient must not have exposed to ant-erbB2 targeted therapy treatment in metastatic setting. Herceptin treatment in the neoadjuvant or adjuvant setting is permitted provide that at least 12 months has elapsed since the last dose of herceptin therapy.
• In phase I part, patient may have received prior anti-erbB-2 targeted treatment in metastatic setting.
• Hormone receptor and menopausal status are not specified. Prior treatment with endocrine therapy in the adjuvant or metastatic setting is permitted provided that therapy be discontinued.
