The FDA is granting emergency use authorization for a coronavirus antibody therapy made by Eli Lilly.

Emergency use authorization is not a full approval, but it means the FDA has seen enough evidence to show that it can work.

The drug, bamlanivimab, is meant to treat people with mild to moderate symptoms, but who are at risk of having more serious illnesses. Eli Lilly says research shows the therapy could prevent patients from needing to be hospitalized.

The drug is similar to a treatment President Trump was given when he was hospitalized for the respiratory illness last month.

Eli Lilly has already begun manufacturing the drug. Eli Lilly executives said they could have as many as 1 million doses available by the end of the year. Eli Lilly is headquartered in Indianapolis.
