Regeneron Pharmaceuticals Inc. said it had begun human trials of a new antibody cocktail for Covid-19, part of an ambitious clinical-testing plan that could lead to a new treatment option by the end of summer if all goes well.

In a statement, the company said it will test a two-antibody combination in a wide variety of people, including those already sick with Covid-19, as well as healthy people at high risk of being exposed to the virus.
