How does the drug work? When there’s a virus in your body, like COVID-19, your immune system makes antibodies to fight it off. But it takes time for your body to make antibodies for a new virus — and in the meantime, you could get very sick. Bamlanivimab is a neutralizing antibody drug. That means it contains man-made antibodies that are similar to the antibodies of patients who recovered from COVID-19. Scientists think that these antibodies may help limit the amount of COVID-19 virus in your body. This could 6 give your body more time to learn how to make its own antibodies. Is this drug safe? Scientists aren’t sure yet. They’re still studying the drug in clinical trials, and there’s a lot they don’t know about the benefits and risks. Because of the COVID-19 pandemic, the FDA has given a temporary Emergency Use Authorization for doctors to use bamlanivimab with 7 certain patients. This means that based on the results of the research so far, the FDA has found that the drug may have more benefits than risks in treating COVID-19 during the pandemic. 6 Coronavirus Prevention Network: https://coronaviruspreventionnetwork.org/coronavirus-vaccine-and-antibody-science/ 7 U.S. Food and Drug Administration: http://pi.lilly.com/eua/bamlanivimab-eua-fda-authorization-letter.pdf Page 4 | PP-BM-US-0009 November 2020 ©Lilly USA, LLC 2020.
