The U.S. has paused another large-scale trial because of potential safety concerns.
Pharmaceutical firm Eli Lilly's Phase 3 trial of a monoclonal antibody treatment was put on hold Tuesday. Neither the company nor the National Institute of Allergy and Infectious Diseases —which is sponsoring the trial —said what the concern was.
A spokesperson from Lilly said it supports the decision from the independent safety board. Lilly's trial was testing the antibody in combination with the anti-viral drug Remdesivir.
