Brief Summary:
The objective of this phase I/ II study is therefore to assess the safety and efficacy of lapatinib in combination with docetaxel in patients with advanced cancer. Only patients in first line treatment for metastatic disease should be included in the present study. It is proposed to start with a phase I part evaluating the safety of lapatinib 1250 mg with docetaxel 75 mg/m² without systematic support of growth factors, starting after the completion and data from the 1000 mg lapatinib +75 mg/m² docetaxel dose level in the EORTC (Bonnefoi) study.The objective of the phase II part will confirm the safety and evaluate efficacy of lapatinib in combination with docetaxel.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: lapatinib Drug: docetaxel Phase 1 Phase 2

Detailed Description:

Docetaxel is a major drug in the treatment of metastatic breast cancer. In HER2 negative tumor, the first line treatment is based on docetaxel containing regimen: docetaxel alone, docetaxel + anthracycline or docetaxel + capecitabine. The efficacy of docetaxel in combination with trastuzumab has been demonstrated in first line metastatic breast cancer overexpressing erbB2 receptor. The response rate (RR) and the time to progression (TTP) observed were even higher than those obtained with paclitaxel +trastuzumab. Docetaxel is more and more used in first line metastatic setting, becoming the first Taxane used in this setting.As trastuzumab may raise safety/tolerability concerns, and as its interest in trastuzumab refractory patients may be limited, there is a need to find new drugs to combine with docetaxel in breast cancer, and to address the specific interaction/safety profile of this combination.The association of lapatinib and docetaxel will be the key combination in metastatic breast cancer development for GSK.The conclusion of a phase I trial EGF 10021 trial conducted in the US which assessed the combination of lapatinib and docetaxel showed that the acceptable optimal tolerated regimen (OTR) of docetaxel (75 mg/m²) was obtained in combination with lapatinib 1250 mg with systematic growth factor support.Data from an ongoing EGF100161 phase I study evaluating the OTR of lapatinib + docetaxel + trastuzumab shows that the association of lapatinib 1250 mg with docetaxel 75mg/m² is haematological toxic and has recently been amended to evaluate lapatinib 1250 mg with docetaxel 75 mg/m² with systematic growth factor support.A phase I/II EORTC study evaluating docetaxel plus lapatinib in neoadjuvant breast cancer patients has just started. The phase I part of this study will evaluate several lapatinib and docetaxel dose levels before conducting phase II.

The phase I part will enrol patients (in cohorts of 3 or 6) to determine in a step-wise approach, the OTR of lapatinib and docetaxel. Patients should not be entered at a higher dose level until all patients in the previous cohort complete the first cycle of treatment, this first cycle is used to determine OTR. Dose modification of lapatinib will be based on any observed toxicity in the treatment period. The OTR will be defined as the dose level at which £ 1 of 6 patients experiences the DLT (dose limiting toxicity).If no DLT is observed in the first 3 patients at a particular dose level during the first cycle (3 week treatment period), recruitment will start at the next dose levelIf 1/3 patients experiences a DLT at a particular dose level, additional 3 patients will be enrolled at that dose level to a total of 6 patients if no DLT occurred againIf 1/6 patients experiences a DLT at a particular dose level, recruitment will start at the next dose levelIf ³ 2/6 patients experiences the same DLT at a particular dose level, the dose level is not considered to be tolerableIf ³ 2/6 patients experiences two distinct DLT at a particular dose level, additional 3 patients will be enrolled at that dose level to a total of 9 patients. If one of the previously described DLT occurred again among the new enrolled patients, the dose level is not considered to be tolerableA total of 12 patients will be treated at the OTR.The OTR is defined as the dose level at which no more than 1 of 6 patients experiences a DLT.The DLT for this study is defined during cycle 1 for the dose escalation step as:· any grade 3-4 non hematological toxicity as defined by the Common Toxicity Criteria, version 3 (with the exclusion of alopecia, nausea, vomiting, diarrhea, infusion related that can be rapidly controlled with appropriate measures)· an absolute neutrophil count (ANC) < 0.5x109 /L lasting for > = 7 day· febrile neutropenia defined as ANC < 1.0 x109 /L and fever at least 38.5°C· thrombocytopenia < 25, 000/µl or thrombocytopenic bleeding requiring transfusion· grade 3 or higher left ventricular cardiac dysfunction or a ≥ 20% decrease from baseline in left ventricular ejection fraction (LVEF) that is also below the institution's lower limit of normal (LLN), and confirmed by a repeat evaluation 1 to 2 weeks following the first evaluation.

Apart within the minus dose levels, G-CSF support should be added only as rescue strategy if severe neutropenia occurred during the first cycle of studied dose.Patients will receive 4 cycles of the association. In case of benefit of the treatment, they should continue the treatment with lapatinib until progression.* patients will be included at level "minus X" only if 2 DLT out of 6 patients based on febrile neutropenia occurred at level "X"
