Two targeted medications designed to treat an aggressive form of breast cancer are being tested in a new study involving 8,000 participants in 50 countries across six continents -- a clinical trial that investigators hope will provide a new model for global cancer research. This trial, dubbed ALTTO (Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization study), will be one of the first global initiatives in which two large, academic breast cancer research networks covering different parts of the world have jointly developed a study in which all care and data collection are standardized, regardless of where patients are treated. The networks are The Breast Cancer Intergroup of North America (TBCI), based in the United States, and the Breast International Group (BIG) in Brussels, Belgium. TBCI consists of six National Cancer Institute (NCI)-funded clinical trials cooperative groups. NCI is part of the National Institutes of Health.
