A new drug to help doctors home in on lymph nodes in breast cancer patients has received the nod from the Food and Drug Administration.
The drug called Lymphoseek is developed by Navidea Biopharmaceuticals Inc. It can help doctors determine if the breast cancer or skin cancer (melanoma) has spread to the patient's lymph nodes.
The FDA said this is the first drug in over three decades approved for use in locating lymph nodes in cancer patients. Lymphoseek was approved on the basis of positive results from two studies involving 332 patients with breast cancer or melanoma. The drug located lymph nodes in a manner comparable to an older drug in these studies.
