What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 3 trials are large pivotal studies comparing the treatment to current standard of care or placebo. Your participation directly contributes to the evidence needed for regulatory approval.

This trial targets 330 participants in total. It began in 2023-05-29 with a primary completion date of 2027-09-01.

Brief Summary

To evaluate if the combination of pivmecillinam and clavulanic acid (PAC) is non-inferior to ciprofloxacin, trimethoprim-sulfamethoxazole or ertapenem as step down oral therapy in patients with febrile UTI caused by extended spectrum beta-lactamase (ESBL) producing Enterobacterales (EPE).

Eligibility Criteria

Inclusion Criteria: 1. Age ≥ 18 years 2. Fever (≥ 38.3 C) or shaking chills at least once at home or in hospital 3. Clinical suspicion of UTI including at least one of the following symptoms: 1. Dysuria, urinary urgency, difficulty urinating, new or worsened urinary incontinence, macroscopic haematuria or increased urinary frequency 2. Low abdominal pain or flank pain with percussion or palpation tenderness over kidneys and/or bladder. 4. Urine (≥ 103 CFU/mL) and/or blood culture positive for EPE\* with susceptibility to pivmecillinam†. 5. In-patient who has received 1-5 days of EPE-active‡ intravenous antibiotics 6. Discontinuing parenteral treatment and starting treatment with oral antibiotics is considered safe according to the treating physician. * EPE refers to ESBL-producing Enterobacterales. This includes Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Klebsiella oxytoca, and Citrobacter koseri. * Susceptibility for pivmecillinam in the study is based on zone diameter breakpoints for pyelonephritis (≥ 20 mm) which was received by personal communication with professor Christian Giske, the chairman of the European Committee of Antimicrobial Susceptibility Testing (EUCAST) (26). * EPE-active intravenous antibiotics refers to EUCAST susceptibility testing and will most often be piperacillin-tazobactam, meropenem or imipenem-cilastatin in the Swedish setting, and less often aminoglycosides or newer beta-lactamase-inhibitor-containing beta-lactam antibiotics (27). Participants who have only received one dose of EPE-active intravenous antibiotics are also eligible and are considered within the "1-5 days" of antibiotics. Patients may only be recruited and randomised once in this trial. Exclusion criteria (any of the following) 1. Known or suspected pregnancy. 2. Known or suspected life-threatening allergy towards beta-lactam antibiotics. 3. Clinical isolate of EPE is resistant to ciprofloxacin, TMX and ertapenem. 4. Severe renal insufficiency with estimated glomerular filtration rate (eGFR) \<10mL/min or requiring any form of dialysis. 5. Severe decompensated liver failure (i.e., child Pugh class B or C). 6. Genetic metabolic diseases associated with severe carnitine deficiency. 7. Megaloblastic haematopoiesis. 8. Co-treatment with valproate or valproic acid (due to interaction with pivmecillinam and ertapenem respectively) 9. Other reason to which patient is unfit to be included in the study according to treating physician, e.g., cognitive impairment preventing informed consent and follow-up, inability to speak and/or read Swedish, missing national personal identification number or missing telephone number preventing follow-up or planned duration of antibiotics \> 10 days due to complicating factors.
