News: Regeneron antibody treatment saving Covid-19 Patients

UK RECOVERY researchers based out of the University of Oxford have discovered a potentially life-saving drug for people hospitalized with Covid-19. The drug, Regeneron’s REGEN-COV has been found to reduce 28 day mortality by 20%.


The drug essentially provides a boost for those patients who have been unable to create their own antibodies to the virus, and have tested negative to antibodies, known as seronegative patients. There may now be 6 fewer deaths of seronegative patients for every 100 that are treated with this drug.


This trial is notably the first to demonstrate the effectiveness of antibody-focused treatments in preventing deaths in hospitalized Covid-19 patients. The study involved 9,785 participants, one third of which showed no ability to produce their own antibodies. Mortality in this group was 30% when receiving standard care, but only 24% when receiving the REGEN-COV, as delivered via. Intravenous drip.


The REGEN-COV drug is a combination of two monoclonal antibodies which are designed to block the infectivity of Covid-19. The antibodies work by binding to two different points on the virus’s spike protein and neutralizing its infectious abilities.


Regeneron head of global clinical development, David Weinreich stated in an interview with Clinical Trials arena,“ The RECOVERY trial has shown that in patients who had not made their own antibodies against SARS-CoV-2, treating them with REGEN-COV antibodies dramatically reduced their risk of dying or being on a ventilator, and also shortened how many days they remained in the hospital.”
