Patient Guide

What you need to know about bamlanivimab (neutralizing antibody treatment for COVID-19) If you’ve recently been diagnosed with COVID-19, you may have a new treatment option: bamlanivimab (bam-la-NIV-i-mab). The research so far shows that for certain people, taking this drug may help limit the amount of virus in the body. This may help their symptoms improve sooner — 1 and they may be less likely to need to go to the hospital. But bamlanivimab is a new drug that’s still being studied, so there’s a lot that scientists don’t know about the benefits and risks. In this easy-to-read guide, you’ll learn about COVID-19 and this new treatment — including its possible benefits and side effects. Together, you and your doctor can decide if this treatment is right for you. Important facts about bamlanivimab: Bamlanivimab is investigational, which means it’s still being studied. Bamlanivimab has not been approved, but has been authorized for emergency use by the United States Food and Drug Administration (FDA), to treat mild to moderate COVID-19 in adults and pediatric patients with positive results of direct SARS-CoV-2 viral testing who are 12 years of age and older weighing at least 40 kg (about 88 pounds), and who are at high risk for progressing to severe COVID-19 and/or hospitalization. FDA has authorized bamlanivimab for emergency use only during the COVID-19 pandemic. Bamlanivimab is authorized for the treatment of mild to moderate COVID-19 in adults and pediatric patients with positive results of direct SARS-CoV-2 viral testing who are 12 years of age and older weighing at least 40 kg (about 88 pounds), and who are at high risk for progressing to severe COVID-19 and/or hospitalization only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of bamlanivimab under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. This guide is not a substitute for the official fact sheet.

What is COVID-19? COVID-19 is a disease caused by a virus called SARS-CoV-2. This is a type 2 of coronavirus. COVID-19 can cause: • Fever or chills • Cough, sore throat, or trouble breathing • Body aches or headache • Runny or stuffy nose • Upset stomach (nausea, vomiting, or diarrhea) • Feeling very tired • Loss of taste or smell Most people with COVID-19 have mild symptoms or no symptoms at all. Other people have serious symptoms, and some even die. Older people and people with 3 certain health conditions are more likely to get very sick from COVID-19. How does COVID-19 spread? COVID-19 spreads easily from person to person. It mainly spreads through the air — when a person who has the disease coughs, sneezes, or 4 talks and someone nearby breathes in their germs. 2 U.S. Centers for Disease Control and Prevention: https://www.cdc.gov/coronavirus/2019-ncov/symptoms-testing/symptoms.html 3 U.S. Centers for Disease Control and Prevention: https://www.cdc.gov/coronavirus/2019-ncov/symptoms-testing/symptoms.html 4 U.S. Centers for Disease Control and Prevention: https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-covid-spreads.html Page 2 | PP-BM-US-0012 November 2020 ©Lilly USA, LLC 2020.

What is bamlanivimab? Bamlanivimab is a neutralizing antibody drug. 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 5 could get very sick. Bamlanivimab 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 virus in your body. This could give your body more time to learn how to make its own antibodies. Bamlanivimab does not have any COVID-19 6 virus in it. In a clinical trial, scientists found that bamlanivimab may limit the amount of virus in the body for people with COVID-19 who take the drug within 10 days of symptoms 7 starting. They may also be less likely to need to go to the hospital. Before you take bamlanivimab, tell your doctor if you: • Have any allergies • Have any diseases or health conditions • Are pregnant or plan to get pregnant • Are breastfeeding or plan to start breastfeeding • Are taking any medicines, including prescription drugs, over-the-counter drugs, vitamins, or herbal products 5 Coronavirus Prevention Network: https://coronaviruspreventionnetwork.org/coronavirus-vaccine-and-antibody-science/ 6 Coronavirus Prevention Network: https://coronaviruspreventionnetwork.org/coronavirus-vaccine-and-antibody-science/ 7 New England Journal of Medicine: SARS-CoV-2 Neutralizing Antibody LY-CoV555 in Outpatients with Covid-19, nejm.org/doi/full/10.1056/NEJMoa2029849 Page 3 | PP-BM-US-0012 November 2020 ©Lilly USA, LLC 2020.

Who is this drug for? 8 Bamlanivimab is a treatment option for people with COVID-19 who: • Are age 12 or older • Weigh 88 pounds or more • Have had mild to moderate symptoms for 10 days or less • Are at high risk to get very sick from COVID-19 This drug is not for people who are already in the hospital because of their COVID-19 symptoms. Am I at high risk? For adults, bamlanivimab may be an option if you: • Are age 65 or older • Have obesity, with a body mass index (BMI) of 35 or higher • Have diabetes, chronic kidney disease, or a condition that weakens the immune system • Take medication that weakens the immune system • Are age 55 or older and have heart disease, high blood pressure, or a long-term lung disease For pediatric patients age 12-17, bamlanivimab may be an option if you: 9 • Have obesity, with a BMI higher than 85 percent of patients your same age or gender • Have heart disease, sickle cell disease, or a long-term lung disease • Have a developmental condition, like cerebral palsy • Regularly use medical technology, like a ventilator or feeding tube If you’re not sure whether bamlanivimab is right for you, talk with your doctor.

How will I take this drug? You only need to get the drug 1 time. It’s an intravenous (IV) infusion, meaning that a nurse will put a small needle in your arm to give you the drug slowly over about 1 hour. The treatment 10 is usually given at a hospital, clinic, or infusion center. Getting any medicine through an IV can cause side effects in the 11 area where the needle went into the skin. These may include: • Pain that lasts a short time during the infusion • Bleeding, bruising, swelling, or soreness • Infection Is bamlanivimab safe? Scientists aren’t sure yet. They’re still studying bamlanivimab 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 12 Use Authorization for doctors to use bamlanivimab with 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. What if I’m pregnant or breastfeeding? Scientists haven’t treated many pregnant or breastfeeding people with bamlanivimab. It’s possible that the drug may have more benefits than risks for them and their babies. Talk to your doctor about your options and your specific situation. 10 U.S. Food and Drug Administration: http://pi.lilly.com/eua/bamlanivimab-eua-fda-authorization-letter.pdf 11 U.S. Food and Drug Administration: http://pi.lilly.com/eua/bamlanivimab-eua-fda-authorization-letter.pdf 12 U.S. Food and Drug Administration: http://pi.lilly.com/eua/bamlanivimab-eua-fda-authorization-letter.pdf Page 5 | PP-BM-US-0012 November 2020 ©Lilly USA, LLC 2020.

What are the side effects? 13 Side effects can range from mild to serious and may include: • Wheezing (noisy breathing that may sound like whistling) or trouble breathing • Swollen lips, face, or throat • Flu-like symptoms (fever, sweating, chills, cough, sore throat, headache, or muscle pain) • Upset stomach (nausea, vomiting, or diarrhea) • Itching, swelling, rash, or hives • Dizziness or low blood pressure • Changes in your heartbeat Tell your doctor or nurse right away if you have any side effects during or after your infusion. Some of these side effects may be signs of a serious allergic reaction. You can also report side effects to FDA MedWatch at www.fda.gov/medwatch or by calling 1-800-FDA-1088. Keep in mind that only a limited number of people have taken bamlanivimab, and scientists are still learning about its side effects and risks. Serious and unexpected side effects may happen. It’s also possible that bamlanivimab could make it harder for your body to fight off a future COVID-19 infection — and it could make a future COVID-19 vaccine less effective for you. Scientists haven’t done specific studies to address these possible risks. If you have any questions, talk with your doctor. 13 U.S. Food and Drug Administration: http://pi.lilly.com/eua/bamlanivimab-eua-fda-authorization-letter.pdf Page 6 | PP-BM-US-0012 November 2020 ©Lilly USA, LLC 2020.

What other treatment options are there for COVID-19? Bamlanivimab is among the first drugs given Emergency Use Authorization to treat people with COVID-19 who are newly diagnosed and have mild to 14 moderate symptoms. Your doctor may also recommend over-the-counter medicines — like pain relievers to help with fever and body aches, or cough medicine so coughing doesn’t keep you awake at night. These medicines can help you feel better, but they won’t help your body fight the virus or make you less likely to need to go to 15 the hospital. And scientists around the world are working hard to develop new treatments to help people get better — and to end the pandemic sooner. What about clinical trials? You may be able to join a clinical trial for a COVID-19 treatment that doesn’t have Emergency Use Authorization yet, but participating doesn’t guarantee you’ll get the treatment. If you’re interested in joining a clinical trial, talk to your doctor.
