INDIANAPOLIS and SAN FRANCISCO and LONDON, March 29, 2021 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY), Vir Biotechnology, Inc. (NASDAQ: VIR) and GlaxoSmithKline plc (LSE/NYSE: GSK) today announced topline data from the expanded Phase 2 BLAZE-4 trial studying low-risk adult patients with mild to moderate COVID-19. Results showed that investigational bamlanivimab (LY-CoV555) 700 mg co-administered with VIR-7831 (also known as GSK4182136) 500 mg demonstrated a 70 percent (p<0.001) relative reduction in persistently high viral load (> 5.27; cycle threshold value < 27.5) at day 7 compared to placebo, meeting the primary endpoint.
In addition, bamlanivimab administered with VIR-7831 demonstrated a statistically significant reduction compared to placebo in the key virologic secondary endpoints of mean change from baseline to days 3, 5 and 7 in SARS-CoV-2 viral load. There were no events for the secondary endpoint of COVID-19 related hospitalization or death by day 29 in either study arm. One patient (in the treatment arm) visited the emergency room for COVID-19 related symptoms. No serious adverse events were seen with co-administration of bamlanivimab and VIR-7831.
Bamlanivimab and VIR-7831 bind to different regions of the spike protein of SARS-CoV-2. Preclinical data suggest the administration of these two investigational antibodies together may provide protection against current variants of SARS-CoV-2 that are resistant to bamlanivimab.
Daniel Skovronsky, M.D., Ph.D., Lilly's chief scientific officer and president of Lilly Research Laboratories said: "The reduction in persistently high viral load is an important virology endpoint that was demonstrated in Lilly's Phase 2 BLAZE-1 trial, and subsequently validated in the Phase 3 trial, to be strongly correlated with the clinical outcome of COVID-19 related hospitalizations and deaths in high-risk patients. These virology data support our belief that bamlanivimab and VIR-7831 together could be a promising option for COVID-19 treatment."
George Scangos, Ph.D., chief executive officer of Vir said: "This virologic evaluation of two antibodies with distinct resistance profiles is an encouraging advance in our fight against the pandemic. VIR-7831 demonstrated positive results in the COMET-ICE trial and recent pre-clinical data suggest that VIR-7831 maintains activity against current circulating variants of concern. Now, with these exciting new data from the BLAZE-4 trial, we believe that VIR-7831 has an important role to play as both monotherapy and in combination with other mAbs. We look forward to continuing conversations with the FDA about VIR-7831 as monotherapy and co-administered with bamlanivimab."
Dr. Hal Barron, chief scientific officer and president R&D, GSK, said: "These early data from the BLAZE-4 trial, coupled with the results of the COMET-ICE trial demonstrating an 85 percent reduction in progression to hospitalization or death using VIR-7831, support our hypothesis that by targeting a highly conserved epitope, VIR-7831 may help deliver benefits to patients. We're continuing to work with regulators to bring VIR-7831 as a monotherapy and potentially co-administered with other monoclonal antibodies to patients in need."
VIR-7831 is an investigational compound, not approved by the U.S. Food and Drug Administration (FDA) or any other regulatory authority. An Emergency Use Authorization (EUA) application for VIR-7831 has been submitted to the FDA, based on the results of the COMET-ICE (COVID-19 Monoclonal antibody Efficacy Trial - Intent to Care Early) trial, which stopped enrollment early based on data from an interim analysis demonstrating an 85 percent reduction in hospitalisation or death in patients receiving VIR-7831 as monotherapy compared to placebo, the primary endpoint of the trial. GSK and Vir will continue discussions with the European Medicines Agency (EMA) and other global regulators to make VIR-7831 available to patients with COVID-19 as soon as possible. The three companies anticipate engaging with global regulators, including the FDA, regarding the possible co-administration of bamlanivimab and VIR-7831 for the treatment of COVID-19.

About BLAZE-4
BLAZE-4 (NCT04634409) is a randomized, double-blind, placebo-controlled trial designed to assess the efficacy and safety of bamlanivimab alone, and bamlanivimab with other neutralizing antibodies including VIR-7831 (GSK4182136) versus placebo for the treatment of symptomatic low-risk COVID-19 in the outpatient setting. Across all treatment arms, the trial will enroll an estimated 1,000 participants in the United States and Puerto Rico.
The primary outcome measure is percentage of participants who have a viral load greater than 5.27 at day 7. Additional endpoints include viral load change from baseline to day 7 in SARS-CoV-2 viral load, percentage of participants who experience COVID-related hospitalization, ER visit or death from baseline through day 29, as well as safety.
About COMET-ICE
COMET-ICE is a multi-center, double-blind, placebo-controlled Phase 3 trial evaluating VIR-7831 in adults with mild or moderate COVID-19 at high risk of progression to severe disease. The trial was stopped for enrollment on March 10, 2021, based on an interim analysis, which demonstrated an
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. A Phase 3 study of bamlanivimab for the prevention of COVID-19 in residents and staff at long-term care facilities (BLAZE-2, NCT04497987) is 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.
About VIR-7831 / GSK4182136
VIR-7831 is an investigational dual-action SARS-CoV-2 monoclonal antibody. Preclinical data suggest it has the potential to both block viral entry into healthy cells and clear infected cells. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. VIR-7831, which incorporates Xencor's Xtend™ technology, also has been designed to achieve high concentration in the lungs to ensure optimal penetration into airway tissues affected by SARS-CoV-2 and to have an extended half-life.
About the Vir and GSK Coronavirus Collaboration
In April 2020, Vir and GSK entered into a collaboration to research and develop solutions for coronaviruses, including SARS-CoV-2, the virus that causes COVID-19. The collaboration uses Vir's proprietary monoclonal antibody platform technology to accelerate existing and identify new anti-viral antibodies that could be used as therapeutic or preventive options to help address the current COVID-19 pandemic and future outbreaks. The companies will leverage GSK's expertise in functional genomics and combine their capabilities in CRISPR screening and artificial intelligence to identify anti-coronavirus compounds that target cellular host genes. They will also apply their combined expertise to research SARS-CoV-2 and other coronavirus vaccines.
About Lilly's COVID-19 Efforts
Lilly is bringing the full force of its scientific and medical expertise to attack the coronavirus pandemic around the world. Existing Lilly medicines are being studied to understand their potential in treating complications of COVID-19, and the company is collaborating with partner companies to discover novel antibody treatments for COVID-19. Lilly is testing both single antibody therapy as well as combinations of antibodies as potential therapeutics for COVID-19. Visit Lilly's COVID-19 disease area page for resources related to Lilly's COVID-19 efforts.
GSK Commitment to Tackling COVID-19
GSK's response to COVID-19 has been one of the broadest in the industry, with three potential treatments in addition to our vaccine candidates in development.
GSK is collaborating with several organisations on COVID-19 vaccines by providing access to our adjuvant technology. In addition to our work with Medicago, a collaboration with Sanofi on an adjuvanted, protein-based vaccine candidate is now in Phase 2. An earlier stage collaboration with SK Bioscience is also ongoing. SK Bioscience receives funding from CEPI and the Bill and Melinda Gates Foundation to develop differentiated, affordable COVID-19 vaccines for supply globally through the COVAX facility. The use of an adjuvant can be of particular importance in a pandemic since it may reduce the amount of vaccine protein required per dose, allowing more vaccine doses to be produced and contributing to protecting more people.
GSK is also working with mRNA specialist, CureVac, to jointly develop next generation, multi-valent mRNA vaccines for COVID-19 with the potential to address multiple emerging variants in one vaccine. GSK will also support manufacturing of up to 100m doses of CureVac's first generation COVID-19 vaccine.
GSK is also exploring potential therapeutic or treatment options for COVID-19 patients. We are collaborating with Vir Biotechnology to develop existing and identify new anti-viral antibodies that could be used as therapeutic or preventive options for COVID-19. We recently reported that an Independent Data Monitoring Committee recommended that the Phase 3 COMET-ICE trial evaluating VIR-7831 as monotherapy for the early treatment of COVID-19 in adults at high risk of hospitalization be stopped for enrolment due to evidence of profound efficacy, based on an interim analysis of data from the trial. We are seeking Emergency Use Authorization in the US and authorizations in other countries. We are also assessing whether an investigational monoclonal antibody, otilimab, can help severely ill COVID-19 patients aged over 70 who experience an overreaction of their immune system.
