Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
RATIONALE: HER2/neu is a receptor (protein) which is found in unusually high amounts in approximately 1 in 5 cancer patients. Scientific evidence suggests that having high amounts of the HER2/neu receptor is important for breast cancer to grow and spread. Women with previously untreated metastatic breast cancer (breast cancer that has spread to other organs) and with high levels of the HER2/neu receptor receive as their usual treatment chemotherapy with one of the approved chemotherapy drugs paclitaxel or docetaxel (called "taxanes") together with another approved drug called "trastuzumab". Chemotherapy drugs, such as paclitaxel and docetaxel, work either by killing tumour cells or by stopping them from dividing. Trastuzumab is an antibody that is given through a vein in the arm and it works by specifically "targeting" the HER2/neu i.e. it attaches to it and "turns it off". Although some of the patients who receive this taxane plus trastuzumab treatment feel better for some months, the cancer usually starts to grow again. Lapatinib is a new drug. Like trastuzumab, it also works by specifically "targeting" the HER2/neu receptor, but it does so in a different way. Lapatinib is not an antibody. It is a pill that is taken daily by mouth. Because lapatinib works in a different way than trastuzumab, it may be worse, as good as or better than trastuzumab in keeping metastatic HER/neu positive cancer from growing. However, this is not known.

Purpose: This randomized Phase III trial is comparing chemotherapy (a taxane) given together with lapatinib with chemotherapy (a taxane) given together with trastuzumab in women with HER2/neu positive breast cancer.
