Three Phase 3 studies in pregnant women of a candidate vaccine designed to prevent infection from the respiratory syncytial virus (RSV) have been stopped following a safety signal. The developer, GlaxoSmithKline Plc, announced a pause in the studies on 18 February and a halt 10 days later. The decision was based on an observation from the study’s independent data monitoring committee during a routine safety assessment. The safety observation wasn’t disclosed. Altogether, the three studies were scheduled to enrol 21,462 individuals, according to clinicaltrials.com.
