As part of a recently launched international phase 3 clinical trial, Montefiore Health System and Albert Einstein College of Medicine are investigating whether the Merck antiviral pill, molnupiravir, now approved in Britain for treating COVID-19, can prevent COVID-19 in unvaccinated individuals living with people who have contracted the disease. Montefiore-Einstein is the first and only New York State site for the trial and was selected due to its diverse patient population and expertise in clinical trials of COVID-19 and other infectious diseases.
