WASHINGTON (AP) -- Drug maker Amgen Inc. said Friday it expanded black box warnings about risks of death and tumor growth of its blockbuster anemia drugs.
The warnings approved by the Food and Drug Administration state that the company's drugs increased death and accelerated tumor growth in patients with early stage breast cancer and cervical cancer. Earlier labeling warned of similar risks in other types of cancer.
