Design: EXPECT1 - prospective observational pilot study; EXPECT2- prospective epidemiological study

Registration Number: Clinical Trials.Gov, Expect 1- NCT04087681; Expect 2- NCT04117113

Primary Objective: COMBACTE-NET aims to provide a large network for rapid evaluation of novel treatment strategies; to generate innovative trial designs to facilitate the registration of novel antibacterial agents; and to design and validate tests to support the diagnosis of patients, identify the most appropriate treatments, and monitor the patient’s response

Secondary Objective(s): EXPECT-1: to assess success factors and barriers for a future Phase 3 randomized controlled trial, where the efficacy of a new vaccine to prevent invasive ExPEC disease will be tested in community-dwelling adults.

EXPECT-2: To estimate the O-serotype distribution of ExPEC isolated from hospitalized patients aged 60 and older with invasive ExPEC disease, and to evaluate the clinical case definition and risk factors.
