EXECUTIVE SUMMARY The world is currently in the midst of a global pandemic. As a global pharmaceutical company, we feel a responsibility to do our part to relieve the burden COVID-19 has placed on countries, communities and families around the world. Clinical trials have shown that monoclonal antibodies may be effective in treating COVID-19. Lilly in partnership with AbCellara has developed a monoclonal antibody called bamlanivimab. Bamlanivimab is a recombinant neutralizing human IgG1 monoclonal antibody directed against the spike protein of SARS- CoV-2. It is designed to block viral attachment and entry into human cells, thus neutralizing the virus. This Antibody Playbook provides information for state, territorial and local public health programs to plan and operationalize a bamlanivimab antibody response to COVID-19. The sections of this document cover specific areas of COVID-19 antibody program planning and implementation, as well as links to resources to assist with those efforts. The sections described in this Playbook may also overlap with routine monoclonal antibody treatment and infusion program activities. This playbook represents guidance based on Lilly’s Clinical Trial experience and National Infusion Center Association (NICA) experience in monoclonal antibody treatments and should not supersede local requirements for infusion sites of care. Please defer to local guidelines. In addition, the Playbook includes information regarding planning and implementation based on varying infusion sites of care, such as: • Existing hospital or community-based infusion sites of care • Existing clinical space (e.g., primary care practices affiliated with hospital systems, urgent care locations, emergency departments, surgery centers, dialysis centers, plasma centers, respiratory clinics and other health care delivery entities approved to administer infusion therapies) We expect most infusion treatments will be administered in one of these aforementioned infusion sites of care, but other infusion sites of care may also be considered. This Playbook provides information that may or may not be applicable to certain spaces depending on existing capabilities. Lilly Bamlanivimab Antibody Playbook | 3 PP-BM-US-0024

IMPORTANT SAFETY INFORMATION There are limited clinical data available for bamlanivimab. Serious and unexpected adverse events may occur that have not been previously reported with bamlanivimab use. Hypersensitivity Including Anaphylaxis and Infusion-Related Reactions There is a potential for serious hypersensitivity reaction, including anaphylaxis with administration of bamlanivimab. If signs and symptoms of a clinically significant hypersensitivity reaction or anaphylaxis occur, immediately discontinue administration and initiate appropriate medications and/or supportive therapy. Infusion-related reactions have been observed with administration of bamlanivimab. Signs and symptoms of infusion related reactions may include: • fever, chills, nausea, headache, bronchospasm, hypotension, angioedema, throat irritation, rash including urticaria, pruritus, myalgia, dizziness. If an infusion-related reaction occurs, consider slowing or stopping the infusion and administer appropriate medications and/or supportive care. Limitations of Benefit and Potential Risk in Patients with Severe COVID-19 Benefit of treatment with bamlanivimab has not been observed in patients hospitalized due to COVID-19. Monoclonal antibodies, such as bamlanivimab, may be associated with worse clinical outcomes when administered to hospitalized patients with COVID-19 requiring high flow oxygen or mechanical ventilation. See Limitations of Authorized Use. Adverse Events Adverse events reported in at least 1% of BLAZE-1 clinical trial participants on bamlanivimab 700 mg and placebo were Nausea (3% vs 4%), Diarrhea (1% vs 5%), Dizziness (3% vs 2%), Headache (3% vs 2%), Pruritus (2% vs 1%) and Vomiting (1% vs 3%). Use in Specific Populations Pregnancy There are insufficient data on the use of bamlanivimab during pregnancy. Bamlanivimab should only be used during pregnancy if the potential benefit outweighs the potential risk for the mother and the fetus. Breastfeeding There are no available data on the presence of bamlanivimab in human or animal milk, the effects on the breastfed infant, or the effects on milk production. Breastfeeding individuals with COVID-19 should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19. Lilly Bamlanivimab Antibody Playbook | 9 PP-BM-US-0024

SECTION 02 SUPPLY AND SCALE OF EFFORT Lilly Bamlanivimab Antibody Playbook | 10 PP-BM-US-0024

SUPPLY AND SCALE OF EFFORT Product Allocation and Supply Lilly has committed to manufacturing up to 1,000,000 vials of bamlanivimab in 2020, with 100,000 doses available to ship within days of authorization. Additionally, Lilly has reached an agreement with the U.S. government to supply 300,000 vials within the first two months after Emergency Use Authorization (EUA) with the option to purchase an additional 650,000 vials through June 2021. Bamlamivimab will be allocated to each state by the Federal Government. Upon EUA, the Federal Government will begin allocating to states immediately and thereafter on a weekly basis. Weekly allocations to state and territorial health departments will be proportionally based on confirmed hospitalizations and COVID-19 cases in each state and territory over the previous seven days, based on data hospitals and state health departments enter into the HHS Protect data collection platform. State Health Authorities will then allocate to individual sites of care within their jurisdiction. If you would like more information about the allocation process or would like to be considered for product allocation, please contact your state health department directly. Scaling Operations The time duration to administer a 700mg/20mL dose of bamlanivimab is 60 minutes at the infusion rate of 200mL/hr (20mL bamlanivimab/180mL 0.9% sodium chloride) for both infusion pumps and gravity infusion. Treatment also requires a post-infusion observation period. It is clinically recommended to monitor patients during infusion and observe patients for at least 1 hour after infusion is complete. Sites of care should follow local requirements when determining appropriate observation periods. If patients will occupy chairs for infusion during this period, rather than a post-treatment monitoring area, planning must account for this time as well. The number of chairs for infusion can be scaled along with the hours of operation to determine the size of the infusion site of care. Infusion sites of care should take into account time for patient intake, IV preparation, infusion and post-infusion observation when determining potential capacity. For example, in Lilly’s monoclonal antibody clinical trial settings, Lilly found a single infusion could take between 165–225 minutes to complete from patient intake to discharge. See Appendix A for more information. The above values could be used to determine a rough approximation of the number of infusion sites of care that may be needed per region. A region can easily modify the number based on changing the capacity assumptions with the various infusion sites of care. Depending on the dispersion of the population in a region, the region may choose to size some infusion sites of care larger than others. Lilly Bamlanivimab Antibody Playbook | 11 PP-BM-US-0024

SECTION 06 EDUCATION AND AWARENESS Lilly Bamlanivimab Antibody Playbook | 23 PP-BM-US-0024

EDUCATION AND AWARENESS Attacking the coronavirus will require a diverse set of approaches, including both vaccines and treatments, such as antibodies. Q. What’s the difference between vaccines and monoclonal antibody drugs? A. While there are some similarities, here’s how they are different: • Monoclonal antibody drugs, like bamlanivimab, provide passive immunity by giving the body antibodies to protect itself. Vaccines provide active immunity by helping the body make its own antibodies to protect itself. • Monoclonal antibody drugs are designed to start working faster than vaccines, while protection provided by vaccines will generally last longer. • Generally, scientists are able to develop antibody treatments faster than they are able to develop vaccines. Developing any approach against COVID-19 involves assessing key factors: Viral exposure Stage of disease At-risk populations A vaccine will not help When to apply the medicine Factors linked to worse an already-infected to prevent the infection or outcomes (e.g., age, patient treat the disease concurrent diseases) Lilly Bamlanivimab Antibody Playbook | 24 PP-BM-US-0024

NEUTRALIZING ANTIBODIES AS POTENTIAL TREATMENTS Identified and characterized using various methods, including from the blood of COVID-19 survivors, neutralizing antibodies target the viral spike protein that SARS-CoV-2 uses to gain entry into host cells. Neutralizing antibodies, therefore, are specifically designed to treat COVID-19. Q. What are antibodies? A. Antibodies are naturally made in our bodies to fight infection. • Whenever the immune system meets a new foreign substance in the body, it makes new antibodies that attack the foreign substance. The next time that substance shows up, the immune system can produce the same antibodies to help the body fight it off before it can make a person sick. These types of naturally occurring antibodies provide active immunity. • Vaccines work in a similar way, helping the body make antibodies to attack specific foreign substances and providing active immunity in the body. • Antibody drugs are different. They are man-made antibodies that are given directly through an infusion or injection rather than prompting the body to make the antibodies for itself. This type of immunity is called passive immunity.

APPENDIX A LILLY MONOCLONAL ANTIBODY CLINICAL TRIAL MODELING INFORMATION Lilly Bamlanivimab Antibody Playbook | 27 PP-BM-US-0024

LILLY MONOCLONAL ANTIBODY CLINICAL TRIAL MODELING INFORMATION Assuming the infusion site of care setup details provided below, this information can be used to model the estimated number of infusions (patients) an infusion site of care can serve, depending on its capacity. Each infusion site of care will vary in terms of the amount of chairs for infusion, staffing considerations, work day length and more. The information provided here is meant as a general guide based upon Lilly’s clinical trial experience. In some cases, ideal criteria are included, such as for observation time. In other instances, such as the consent and intake time, there are estimated ranges shown, with “+” or “-” conditions in parentheses. Infusion Timing Criteria Details Additional Notes Consent and intake time 30 min (+/- 15 min) Consent and intake may occur outside of the infusion chair, such as at the prescriber’s location, and consent and intake time may vary per patient. IV prep time 30 min This step usually does not take place until the patient is in the chair for infusion and vascular access has been obtained. Infusion time 60 min (+30 min) Infusion time should be a minimum of 60 minutes, although more time may be necessary. It is clinically recommended to monitor patients during infusion and observe Observation time* 60 min patients for at least 1 hour after infusion is complete, although more time may be necessary. Sites of care should follow local requirements when determining appropriate observation periods. TOTAL TIME 165–225 min This represents the estimated total time from consent through observation of the patient. *It is recommended that infusion sites of care have a protocol in place for patients who refuse to stay for post-infusion observation. For example, this may include an AMA form, release of responsibility waiver, etc. Lilly Bamlanivimab Antibody Playbook | 28 PP-BM-US-0024
