Summary
Brief summary (as posted)
HER2-positive cancer is a cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). HER2 promotes the growth of certain cancer cells. This study will test an experimental drug called DS-8201a that has not been approved by the health authorities yet. DS-8201a will be tested for safety in patients with advanced solid malignant tumors that test positive for HER2. It also will test how DS-8201a moves within the body (pharmacokinetics).
