TARRYTOWN, N.Y., Nov. 8, 2021 /PRNewswire/ --
Single dose of REGEN-COV (1,200 mg subcutaneous) reduced the risk of COVID-19 by 81.6% during the pre-specified follow-up period (months 2-8), maintaining the 81.4% risk reduction previously reported during month 1
During the 8-month assessment period there were 0 hospitalizations for COVID-19 in the REGEN-COV group and 6 in the placebo group
The fully human antibodies in REGEN-COV were developed to provide long-lasting protective effects without any artificial mutations or sequences
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced additional positive results from a Phase 3 trial jointly run with the National Institute of Allergy and Infectious Diseases (NIAID), which assessed use of a single dose of investigational REGEN-COV® (1,200 mg administered via 4 subcutaneous injections) to prevent COVID-19 in uninfected individuals. The new analyses show REGEN-COV reduced the risk of contracting COVID-19 (i.e., laboratory-confirmed symptomatic SARS-CoV-2 infections) by 81.6% during the pre-specified follow-up period (months 2-8), maintaining the 81.4% risk reduction during the first month after administration, which was previously reported in The New England Journal of Medicine.
"Today's new data demonstrate how a single dose of REGEN-COV can help protect people from COVID-19 for many months after administration," said Myron S. Cohen, M.D., who leads the monoclonal antibody efforts for the NIH-sponsored COVID Prevention Network (CoVPN) and is Director of the Institute for Global Health & Infectious Diseases at the University of North Carolina at Chapel Hill. "These results demonstrate that REGEN-COV has the potential to provide long-lasting immunity from SARS-CoV-2 infection, a result particularly important to those who do not respond to COVID-19 vaccines including people who are immunocompromised."
In results previously published, the trial met its primary endpoint, reducing the risk of COVID-19 (i.e., laboratory-confirmed symptomatic SARS-CoV-2 infections) by 81.4% within 1 month of receiving REGEN-COV (p
