MacroGenics, Inc.

MacroGenics is a biotechnology company developing cancer treatments based on antibodies, which are proteins the body makes to fight disease. The company is testing several experimental drugs in clinical trials, where they are given to patients to see if they work and are safe. Most of MacroGenics's treatments are designed to work in different ways: some help the immune system attack cancer cells, while others deliver toxic payloads directly to tumors. The company was founded in 2000 and is based in Maryland.
