Johnson & Johnson said it has paused the advanced clinical trial of its experimental coronavirus vaccine because of an unexplained illness in one of the volunteers.
The move comes around a month after AstraZeneca also suspended trials of its experimental coronavirus vaccine because of a neurological complication in a volunteer in Britain.
“Following our guidelines, the participant’s illness is being reviewed and evaluated by the ENSEMBLE independent Data Safety Monitoring Board (DSMB) as well as our internal clinical and safety physicians,” the company said in a statement.
ENSEMBLE is the name of the study.
Johnson & Johnson said there is a “significant distinction” between a study pause and a regulatory hold on a clinical trial.
“A study pause, in which recruitment or dosing is paused by the study sponsor, is a standard component of a clinical trial protocol,” the drugmaker said.
