Summary

This is an open-label, non-randomized, multi-center study of lapatinib plus paclitaxel to evaluate safety, tolerability and efficacy in Japanese patients with ErbB2 over expressing advanced or metastatic breast cancer. Lapatinib 1500mg/day will be administered in combination with paclitaxel 80mg/m2/week. Lapatinib and paclitaxel will be administered until disease progression or withdrawal from the study due to unacceptable toxicity.

The study will proceed in two phases. The first phase (Phase I part) will lead to evaluate safety and tolerability of lapatinib taken together with paclitaxel in the first 6 subjects. Pharmacokinetic profile also will be evaluated as the secondary objects.

Then the study will move to the next treatment phase (Phase II part) to evaluate further safety and clinical activity, if no major safety concerns are raised during Phase I part. The primary objective of the study is to evaluate overall survival (OS), and the secondary objectives are Objective tumour response rate (ORR), Duration of response, Time to response, Clinical benefit and Progression-free survival (PFS) in 12 subjects.

Interventions

DRUG

Lapatinib in combination with weekly paclitaxel

These subjects will receive weekly paclitaxel (80 mg/m2 IV for 3 weeks in a 4 week cycle) plus lapatinib (1500 mg once daily, starting on the second day of phase I). Subjects will receive a daily dose of lapatinib until disease progression or withdrawal from study treatment due to unacceptable toxicity or withdrawal of consent. Study completion is defined as deaths after administering study treatment for more than once. Subjects will be treated with paclitaxel for standard of 6 cycles, and may be continued at the discretion of investigators. If the subject experiences progression, an unacceptable toxicity related to paclitaxel, or termination of lapatinib therapy, paclitaxel therapy must be terminated any time of study period, even before 6 cycles of paclitaxel are given.
