Ten out of 186 people who received the treatment contracted COVID-19 but did not experience symptoms.
Those participants also had smaller viral loads and a shorter period of viral shedding, the company said.
The Westchester-based biotechnology giant said the treatment could be used as a passive vaccine following the Phase 3 results in the trial jointly run by the National Institute of Allergy and Infectious Diseases.
In November, the Food and Drug Administration greenlit Regenerons therapy for mild to moderate COVID-19 cases in adults and children.
A passive vaccine involves delivering virus-fighting antibodies into the body unlike traditional vaccines which activates a persons immune system to develop their own antibodies.
Full results from the trial are expected in the second quarter.
