An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the study vaccine. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. Solicited local AEs were precisely defined local events that participants were specifically asked about and which were noted by participants in the diary. Solicited local AEs included injection-site pain/tenderness, injection-site erythema and injection-site swelling/induration.

ExPEC4V is an investigational product developed by Johnson & Johnson for the prevention of extraintestinal pathogenic Escherichia coli, or ExPEC. It is being studied in healthy adult volunteers rather than in patients with an active infection. ExPEC4V has completed three clinical trials and remains in clinical development.
ExPEC4V is being developed for the prevention of extraintestinal pathogenic Escherichia coli, a group of E. coli strains that cause infections outside the intestinal tract. The clinical program has enrolled healthy adult participants to evaluate the product rather than treating people with established disease.
ExPEC4V is developed by Johnson & Johnson, which trades on the New York Stock Exchange under the ticker JNJ. The company has sponsored the clinical program for the candidate, including the Phase 1 and Phase 2 studies conducted in the United States and Japan.
ExPEC4V is in Phase 2 development. Three trials have been completed, including two Phase 2 studies and one Phase 1 study, and no trials are currently listed as active. ExPEC4V is investigational and has not been approved for any indication.
Three completed trials have evaluated ExPEC4V: NCT02546960, a Phase 2 study in 848 healthy adults in the United States; NCT03500679, a Phase 2 study in 100 healthy participants aged 18 and older in the United States; and NCT02748967, a Phase 1 study in 48 healthy Japanese adults in Japan.
Yes. ExPEC4V (4 : 4 : 4 : 4) is another way the candidate is written, so both names refer to the same Johnson & Johnson development program for prevention of extraintestinal pathogenic Escherichia coli. The Phase 1 study NCT02748967 also refers to the candidate as JNJ-63871860.
