AbCellera-Discovered Antibody, Bamlanivimab, to be Developed with VIR-7831 for the Treatment of COVID-19

January 27, 2021

Bamlanivimab’s powerful neutralization of the virus responsible for COVID-19 provides therapeutic backbone for new therapies to expand protection against viral variants

VANCOUVER, British Columbia--(BUSINESS WIRE)-- AbCellera (Nasdaq: ABCL) today announced that bamlanivimab (LY-CoV555), a human antibody discovered by AbCellera and developed with Eli Lilly and Company (Lilly), will be evaluated together with VIR-7831, an antibody developed by Vir Biotechnology, Inc. and GlaxoSmithKline, as a potential COVID-19 therapy in low-risk patients with mild to moderate COVID-19. Bamlanivimab is currently a component in all Lilly’s antibody-based COVID-19 therapies, which include bamlanivimab alone, and bamlanivimab and etesevimab together. Lilly will expand the ongoing BLAZE-4 trials to evaluate bamlanivimab together with VIR-7831. Details about Lilly’s trial are available here.

Bamlanivimab is a human antibody that reduces the risk of contracting COVID-19 by up to 80% in people exposed to the virus, prevents COVID-19 related deaths, and reduces hospitalizations by 70%-80% in patients recently diagnosed with mild to moderate COVID-19. Bamlanivimab, which was discovered by AbCellera in March 2020 and reached human clinical trials 90 days later, was granted Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) in November 2020.

“To date, more than 100,000 patients have received bamlanivimab, and the data from clinical trials show its use saves lives and prevents hospitalizations,” said Carl Hansen, Ph.D., CEO and President of AbCellera. “Bamlanivimab alone remains an important antibody therapy, and we are pleased it will be evaluated with VIR-7831 to potentially expand the impact of antibody therapies on viral variants.”

To date, bamlanivimab 700 mg has been authorized in the United States, Canada, Germany, Israel, Hungary, United Arab Emirates, Kuwait, Saudia Arabia, and Panama to treat mild to moderate COVID-19 in high-risk patients.

About AbCellera’s Response to COVID-19

Bamlanivimab was developed from an antibody that was discovered from the blood of a recovered COVID-19 patient using AbCellera’s pandemic response platform, in partnership with the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID). Within one week of receiving the sample, AbCellera screened over five million antibody-producing cells to identify and isolate approximately 500 unique antibodies that bind to SARS-CoV-2, the virus that causes COVID-19. The binding antibodies were then tested by AbCellera, the VRC, and Lilly to find those most effective in neutralizing the virus. Bamlanivimab was selected as the lead candidate from this group of antibodies and was the first therapeutic candidate specifically developed against SARS-CoV-2 to enter human clinical trials in North America. Bamlanivimab was the first monoclonal antibody to receive EUA from the U.S. FDA and is currently being assessed in several clinical trials alone and together with other antibodies.

AbCellera’s pandemic response capabilities were developed over the past two years as part of the Defense Advanced Research Projects Agency (DARPA) Pandemic Prevention Platform (P3) program. The goal of the P3 program is to establish a robust technology platform for pandemic response capable of developing field-ready medical countermeasures within 60 days of isolation of an unknown viral pathogen. AbCellera’s ongoing efforts to respond to the pandemic have identified more than 2,300 unique anti-SARS-CoV-2 human antibodies from multiple patient samples. These antibodies are in various stages of testing by AbCellera and its partners.

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. 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 NIAID VRC. 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. 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.

Bamlanivimab is authorized in the U.S. for the treatment of mild to moderate COVID-19 in adults and pediatric patients 12 years and older with a positive COVID-19 test, who are at high risk for progressing to severe COVID-19 and/or hospitalization. Bamlanivimab should be administered as soon as possible after a positive COVID-19 test and within 10 days of symptom onset.
