J&J enrolls about 45,000 participants for late-stage COVID-19 vaccine trial
(Reuters) – Johnson & Johnson said on Thursday it has enrolled about 45,000 participants for the first late-stage trial of its COVID-19 single-dose vaccine candidate and that it expects interim data by late-January.
The company, however, is lagging rivals Pfizer Inc and Moderna Inc in the race for a vaccine to combat the COVID-19 pandemic that has infected about 75 million people globally.
J&J’s study, named Ensemble, is being conducted by its unit Janssen, the drugmaker said in a statement.
While seven countries have already authorized the joh of Pfizer and German firm BioNTech’s candidates, Moderna’s rival vaccine was set for regulatory authorization this week in the United States.
J&J also said it plans to submit an emergency use authorization application to the U.S. Food and Drug Administration (FDA) in February if the data from the study is safe and effective.
The company had earlier this month announced cuts in enrollment for the vaccine trial from its original plan for 60,000, as higher rates of COVID-19 infections amid a worsening pandemic should generate the data it needs with fewer study subjects.
