On June 11, 2020, Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) announced initiation of the first clinical trial of REGN-COV2, its investigational dual antibody cocktail for the prevention and treatment of COVID-19. The REGN-COV2 clinical program will consist of four separate study populations: hospitalized COVID-19 patients, non-hospitalized symptomatic COVID-19 patients, uninfected people in groups that are at high-risk of exposure (such as healthcare workers or first responders), and uninfected people with close exposure to a COVID-19 patient (such as the patient's housemate). The placebo-controlled trials will be conducted at multiple sites. "We have created a unique anti-viral antibody cocktail with the potential both to prevent and treat infection, and also to preempt viral “escape,” a critical precaution in the midst of an ongoing global pandemic," said George D. Yancopoulos, MD, PhD,, Co-Founder, President and Chief Scientific Officer of Regeneron. "REGN-COV2 could have a major impact on public health by slowing spread of the virus and providing a needed treatment for those already sick – and could be available much sooner than a vaccine. The antibody cocktail approach may also have long-term utility for elderly and immuno-compromised patients, who often do not respond well to vaccines. Ultimately, the world needs multiple solutions for COVID-19, and the innovative biopharma industry is collectively working hard to help as many people as possible with a variety of complementary approaches." Regeneron scientists evaluated thousands of fully-human antibodies produced by the company's proprietary VelocImmune® mice, which have been genetically-modified to have a human immune system, as well as antibodies isolated from humans who have recovered from COVID-19.
