Phase 2, randomised, double-blind, 2-cohort study in hospitalised adults with complicated urinary tract infection (cUTI), including acute pyelonephritis. All study cohorts were randomised in a 2:1 ratio. Treatment duration for each cohort was 7 to 10 days. Patients were not permitted to switch to oral therapy.
Cohort 1: 15 patients treated with cefepime 1 g/AAI101 500 mg intravenous (i.v.) infusion over 2 hours once every 8 hours (q8h), and 7 patients treated with cefepime 1 g i.v. infusion over 2 hours q8h.
Cohort 2: 15 patients treated with cefepime 2 g/AAI101 750 mg i.v. infusion over 2 hours q8h, and 8 patients treated with cefepime 2 g i.v. infusion over 2 hours q8h.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria:
• Male or female patients with clinical signs and/or symptoms of cUTI or acute pyelonephritis that were expected to require hospitalization and initial treatment with at least 7 days of i.v.
antibiotics.
Exclusion criteria:
* Patients with concurrent infection that would interfere with evaluation of response to the study antibiotics;
* Patients needing concomitant systemic antimicrobial agents in addition to those designated in the various study treatment groups;
* Patients receiving effective antibacterial drug therapy for any indication for a continuous duration of \>24 hours during the previous 72 hours before the study-qualifying baseline urine was obtained or receiving any amount of potentially therapeutic antibacterial therapy after collection of the pre-treatment baseline urine culture and before administration of the first dose of study drug;
* Patients likely to require the use of an antibiotic for cUTI or acute pyelonephritis prophylaxis during participation in the study;
* Patients with confirmed fungal urinary tract infection at the screening visit (with ≥103 fungal colony forming units \[CFU\]/mL); or
* Patients with intractable urinary infection at baseline that the Investigator anticipated would require \>10 days of study drug therapy were excluded from participation
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.
