GSK and Vir Biotechnology Announce EMA Review of Dual-Action Monoclonal Antibody VIR-7831 for the Early Treatment of COVID-19 - Seite 2
GSK is planning to submit a full Marketing Authorization Application (MAA) to the EMA which will include the data from the COMET-ICE trial.
The multi-center, double-blind, placebo-controlled COMET-ICE trial investigated VIR-7831 in adults with mild or moderate COVID-19 who are at high risk of progression to severe disease. The Phase 2 lead-in portion of the trial, which served as the first-in-human assessment, evaluated the safety and tolerability of a single 500 mg intravenous (IV) infusion of VIR-7831 or placebo over a 14-day period in 21 non-hospitalized adults enrolled across the United States. In October 2020, based on a positive evaluation of safety and tolerability data of VIR-7831 from the lead-in part of the trial by an Independent Data Monitoring Committee, the trial began enrolling patients in North America and additional sites in South America and Europe in the global Phase 3 portion of the trial.
In March 2021, an Independent Data Monitoring Committee recommended that the COMET-ICE trial be stopped for enrollment due to evidence of profound efficacy but is continuing to follow study participants for 24 weeks. Additional results, including epidemiology and virology data, will be forthcoming once the trial is completed.
The Phase 3 portion of the trial assessed the safety and efficacy of a single IV infusion of VIR-7831 (500 mg) or placebo in non-hospitalized participants globally. The interim analysis included 291 patients in the treatment arm and 292 patients in the placebo arm. Among those studied, 63% were Hispanic or Latinx and 7% were Black or African American. The primary efficacy endpoint is the proportion of patients who have progression of COVID-19 as defined by the need for hospitalization for at least 24 hours or death within 29 days of randomization.
About the VIR-7831 Clinical Development Program
In addition to the COMET-ICE trial, the full COMET clinical development program for VIR-7831 includes:
- COMET-PEAK: An ongoing Phase 2 trial with two parts: to compare the safety and viral kinetics of 500 mg intramuscularly (IM) administered VIR-7831 to 500 mg intravenously administered VIR-7831 among low-risk adults with mild to moderate COVID-19 and to evaluate the similarity in pharmacokinetics between VIR-7831 manufactured by different processes.
- COMET-TAIL: A Phase 3 trial expected to begin in the second quarter of 2021 in high-risk adults to assess whether IM-administered VIR-7831 can reduce hospitalization or death due to COVID-19.
COMET-STAR: A Phase 3 trial expected to begin in the second quarter of 2021 in uninfected adults at high risk to determine whether IM-administered VIR-7831 can prevent
