INDIANAPOLIS, Feb. 26, 2021 /PRNewswire/ -- The U.S. government has agreed to purchase a minimum of 100,000 doses of bamlanivimab (LY-CoV555) 700 mg and etesevimab (LY-CoV016) 1400 mg together, Eli Lilly and Company (NYSE: LLY) announced. Bamlanivimab and etesevimab together recently received emergency use authorization for the treatment of recently diagnosed, mild to moderate COVID-19 in patients who are at high risk of progressing to severe COVID-19 and/or hospitalization. Additionally, the National Institutes of Health (NIH) recently updated the COVID-19 Treatment Guidelines to recommend the use of bamlanivimab plus etesevimab for the treatment of outpatients with mild to moderate COVID-19 who are at high risk of clinical progression.

The purchase agreement is for $210 million and doses will be delivered through March 31, 2021. The U.S. government will have the option to purchase up to an additional 1,100,000 doses through November 25, 2021, under the same terms as the base agreement and subject to agreement from Lilly, product availability and the medical need in the U.S.

This purchase adds to the supply of neutralizing antibodies already available for use in the U.S. The government has already committed to purchase a total of 1,450,000 doses of bamlanivimab alone, which includes more than 1 million doses that have been delivered and an agreement to deliver 450,000 additional doses by March 31, 2021. The government has said it will provide neutralizing antibodies at no out-of-pocket cost to patients, although healthcare facilities may charge a fee for the product's administration.

"Every day, thousands of Americans are diagnosed with COVID-19, with many at high risk of progressing to more severe disease. In our clinical trials, Lilly's neutralizing antibody therapies significantly reduced the risk of hospitalizations and death," said David A. Ricks, Lilly's chairman and CEO. "The NIH recommendation provides additional guidance to clinicians treating high-risk patients with COVID-19, who now have another treatment option that could keep more people out of the hospital and save lives."

Lilly will begin shipping these additional doses immediately. The federal government directs the distribution of bamlanivimab alone and bamlanivimab and etesevimab together. Additional details can be viewed at the online federal dashboard and healthcare facilities can order directly from the distributor here.

Use in Specific Populations
Pregnancy
There are insufficient data on the use of bamlanivimab and etesevimab together and bamlanivimab alone during pregnancy. Bamlanivimab and etesevimab together and bamlanivimab alone 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 or etesevimab 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.

About bamlanivimab
Bamlanivimab is a recombinant, neutralizing human IgG1 monoclonal antibody (mAb) 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, potentially treating COVID-19. Bamlanivimab emerged from the collaboration between Lilly and AbCellera to create antibody therapies for the prevention and treatment of COVID-19. Lilly scientists rapidly developed the antibody in less than three months after it was discovered by AbCellera and the scientists at the National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center. It was identified from a blood sample taken from one of the first U.S. patients who recovered from COVID-19.

Lilly has successfully completed a Phase 1 study of bamlanivimab in hospitalized patients with COVID-19 (NCT04411628). A Phase 2/3 study in people recently diagnosed with COVID-19 in the ambulatory setting (BLAZE-1, NCT04427501) is ongoing, and results from the Phase 2 cohorts of BLAZE-1 were published in the New England Journal of Medicine and The Journal of the American Medical Association. A Phase 3 study of bamlanivimab alone or bamlanivimab and etesevimab together in residents and staff at long-term care facilities (BLAZE-2, NCT04497987) is also ongoing. In addition, bamlanivimab is being tested in the National Institutes of Health-led ACTIV-2 study in ambulatory COVID-19 patients.

About etesevimab
Etesevimab (LY-CoV016, also known as JS016) is a recombinant fully human monoclonal neutralizing antibody, which specifically binds to the SARS-CoV-2 surface spike protein receptor binding domain with high affinity and can block the binding of the virus to the ACE2 host cell surface receptor. Point mutations were introduced into the native human IgG1 antibody to mitigate effector function. Lilly licensed etesevimab from Junshi Biosciences after it was jointly developed by Junshi Biosciences and the Institute of Microbiology, Chinese Academy of Science (IMCAS). Junshi Biosciences leads development in Greater China, while Lilly leads development in the rest of the world.

Lilly has successfully completed a Phase 1 study (NCT04441931) of etesevimab in healthy U.S. volunteers to evaluate the safety, tolerability, pharmacokinetics and immunogenicity. A Phase 2/3 study in people recently diagnosed with COVID-19 in the ambulatory setting (BLAZE-1, NCT04427501) is ongoing. Junshi Biosciences has completed a similar Phase 1 study in healthy volunteers in China and has initiated Phase 1b/2 trials in COVID-19 patients globally.
