Vir on another explosive run up 5% pre market27 Jan 2021 11:56
INDIANAPOLIS, SAN FRANCISCO and LONDON, Jan. 27, 2021 (GLOBE NEWSWIRE) -- Eli Lilly and Company (NYSE: LLY), Vir Biotechnology, Inc. (NASDAQ: VIR) and GlaxoSmithKline plc (LSE/NYSE: GSK) today announced a collaboration to evaluate a combination of two COVID-19 therapies in low-risk patients with mild to moderate COVID-19. Lilly has expanded its ongoing BLAZE-4 trial to evaluate the administration of bamlanivimab (LY-CoV555) 700mg with VIR-7831 (also known as GSK4182136) 500mg, two neutralizing antibodies that bind to different epitopes of the SARS-CoV-2 spike protein. This unique collaboration marks the first time that monoclonal antibodies from separate companies will be brought together to explore potential outcomes.
Bamlanivimab is a neutralizing antibody directed against the spike protein of SARS-CoV-2 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. Bamlanivimab is authorized for emergency use for the treatment of mild to moderate COVID-19 in patients who are at high risk for progressing to severe COVID-19 and/or hospitalization.
VIR-7831 is a dual-action monoclonal antibody that was selected for clinical development based on its potential to both block viral entry into healthy cells and clear infected cells, as well as its potential to provide a high barrier to resistance. In pre-clinical trials, the antibody has shown the ability to neutralize the SARS-CoV-2 live virus by binding to an epitope on SARS-CoV-2 shared with SARS-CoV-1, indicating that the epitope is highly conserved, which may make it more difficult for escape mutants to develop. Vir and GSK are advancing VIR-7831 as part of their collaboration to research and develop solutions for coronaviruses, including SARS-CoV-2.
“Bamlanivimab is a potent antibody – with data from multiple Phase 2 and 3 clinical trials, which have demonstrated robust evidence for both treating and preventing COVID-19,” said Daniel Skovronsky, M.D., Ph.D., Lilly’s chief scientific officer and president of Lilly Research Laboratories. “With a virus like SARS-CoV-2, it’s expected that variants could emerge that require new therapeutic options, which is why Lilly is studying bamlanivimab together with other neutralizing antibodies, including etesevimab. Adding VIR-7831 to our study is an important part of our commitment to develop therapies to treat current and future strains of COVID-19 until vaccines are widely available and utilized.”
“We believe that VIR-7831 has significant potential as a single agent, and we are optimistic about the pending interim data from two Phase 3 trials evaluating its potential for early treatment and in hospitalized patients,” said George Scangos, Ph.D., chief executive officer of Vir.
