Inclusion Criteria:
* Participant must be willing to share relevant medical information pertaining to medical history and to share medical records relevant to the medical events identified as suspected cases of invasive extraintestinal pathogenic Escherichia coli disease (IED), urinary tract infections (UTI), or acute bacterial prostatitis (ABP) occurring during the study observation period
* Participant must have a history of UTI in the past 2 years for which evidence of diagnosis was verified by the investigator. In case of a recent history of UTI or ABP, the condition must have resolved greater than (\>)14 days prior to randomization
* Before randomization, participants who were born female must be either postmenopausal or permanently sterile, and not intending to conceive by any methods
* Participant must be willing to provide verifiable identification, has means to be contacted and to contact the investigator during the study
Exclusion Criteria:
* Participant has end-stage renal disease for which dialysis is required
* Participant has a contraindication to intramuscular (IM) injections and blood draws example, due to bleeding disorders or a history of difficult blood draws
* Participant has a history of acute polyneuropathy (for example, Guillain-Barre syndrome) or chronic inflammatory demyelinating polyneuropathy
* Participant has received any Escherichia coli (E. coli) or extraintestinal pathogenic Escherichia coli (ExPEC) vaccine
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
