Regeneron Pharmaceuticals is testing a new coronavirus antibody drug in humans as part of a federally funded, wide-ranging, placebo-controlled clinical trial.

Why it matters: The drug candidate is going to be tested as a way to both treat and prevent the infection.

Details: Regeneron is testing its "antibody cocktail" in four patient groups, according to the company's announcement:

  • "Hospitalized COVID-19 patients, non-hospitalized symptomatic COVID-19 patients, uninfected people in groups that are at high-risk of exposure (such as health care workers or first responders) and uninfected people with close exposure to a COVID-19 patient (such as the patient's housemate)."

Between the lines: Regeneron has had some success with this idea of combining antibodies into one treatment as a way to ward off invading diseases — most recently with a treatment for the Ebola virus.

  • Eli Lilly similarly is testing its own coronavirus antibody treatment and hopes to get emergency authorization by the fall, Reuters reported.

Yes, but: This is still just the beginning of a phase one trial. We're several months away from knowing whether these treatments are safe and effective against the virus and disease.

By any standard, no matter how you look at it, the U.S. is losing its war against the coronavirus.

Why it matters: The pandemic is not an abstraction, and it is not something that’s simmering in the background. It is an ongoing emergency ravaging nearly the entire country, with a loss of life equivalent to a Sept. 11 every three days — for four months and counting.

India is set to reinstate mandatory lockdowns for cities as medical facilities across the country are strained due to a recent surge in new coronavirus infections, the New York Times reports.

Why it matters: Roughly four months ago, India's Prime Minister Narendra Modi announced a national lockdown to prevent the spread of the virus, hoping to avoid the large-scale crisis it's now experiencing.
