Vir Biotechnology and GSK announce global expansion to Phase 3 of COMET-ICE study evaluating VIR-7831 for the treatment of COVID-19
- Independent Data Monitoring Committee recommended on
September 30, 2020that the study continue into Phase 3 based on a positive evaluation of safety and tolerability data from the Phase 2 lead-in
- Initial Phase 3 results may be available as early as the end of 2020; results for the primary endpoint are expected in the first quarter of 2021, with current estimates at
- If successful, VIR-7831 has the potential to advance outpatient treatment for COVID-19
- Patient enrollment underway; website live at https://vircovid19study.com/
The Phase 3 portion of the COMET-ICE study will assess the safety and efficacy of a single intravenous infusion of VIR-7831 or placebo in approximately 1,300 non-hospitalized participants globally (670 patients in the treatment arm and approximately 670 patients in the placebo arm). The primary efficacy endpoint is the proportion of patients who have progression of COVID-19 as defined by the need for hospitalization or death within 29 days of randomization. Interim analyses are planned to evaluate safety, futility and efficacy, the results of which may be available as early as the end of 2020. Results for the primary endpoint are expected in the first quarter of 2021, with current estimates at
The COMET clinical development program for VIR-7831 includes two additional planned trials – one for the treatment of hospitalized patients and another for the prevention of symptomatic infection. The companies also expect to start a Phase 1b/2a trial in the second half of 2020 evaluating VIR-7832, a second investigational SARS-CoV-2 neutralizing antibody that shares the same characteristics as VIR-7831, plus enhanced effector function, which may confer additional efficacy in treatment or prophylaxis by stimulating a T-cell response.
About VIR-7831 / GSK4182136
VIR-7831 (GSK4182136) is a monoclonal antibody that has shown the ability to neutralize SARS-CoV-2 live virus in vitro and in vivo. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (also known as SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. VIR-7831/GSK4182136 has been engineered with the potential to enhance lung bioavailability and have an extended half-life.
VIR-7832 is a monoclonal antibody that has shown the ability to neutralize SARS-CoV-2 live virus in vitro. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (also known as SARS), indicating that the epitope is highly conserved, which may make it more difficult for escape mutants to develop. VIR-7832 has been engineered with the potential to enhance lung bioavailability, have an extended half-life, and function as a therapeutic and/or prophylactic T cell vaccine.

Actual results may differ materially from these forward-looking statements. Forward-looking statements contained in this press release include statements regarding the potential benefits of Vir’s collaboration with GSK, the expected timing of clinical study results for VIR-7831, Vir-7831’s potential to treat COVID-19 and its expected clinical activity, clinical trials for VIR-7832, the ability of VIR-7832 to function as a therapeutic and/or prophylactic vaccine and its clinical activity, as well as Vir’s ability to identify new anti-viral antibodies and its technologies, as well as Vir’s ability to address the current COVID-19 pandemic and future outbreaks of the disease. Many factors may cause differences between current expectations and actual results, including unexpected safety or efficacy data or results observed during clinical trials, challenges in identifying new anti-viral antibodies, challenges in neutralizing SARS-CoV-2 or in identifying and inhibiting cellular targets, difficulties in obtaining regulatory approval, challenges in accessing manufacturing capacity, clinical site activation rates or clinical trial enrollment rates that are lower than expected, changes in expected or existing competition, delays in or disruptions to Vir’s business or clinical trials due to the COVID-19 pandemic, geopolitical changes or other external factors, and unexpected litigation or other disputes. Other factors that may cause actual results to differ from those expressed or implied in the forward-looking statements in this press release are discussed in Vir’s filings with the
GSK Cautionary Statement Regarding Forward-Looking Statements
