The results appear online this week in The New England Journal of Medicine. An announcement made on August 12, 2019, noted that the study leaders halted the trial early, on August 9, 2019, as recommended by an independent data and safety monitoring board based on its review of preliminary data from 499 study patients. The preliminary analysis found that both mAb114 and REGN-EB3 performed better than ZMapp. The fourth drug, remdesivir, performed similarly to ZMapp. Today’s publication provides a comprehensive analysis of the full dataset from nearly 200 additional patients enrolled in the clinical study.
