Efficacy of an Empirical Treatment With Amoxicillin-clavulanate (AC) Compared to the Combination Amoxicillin-clavulanate and Ciprofloxacin (AC+C) in the Outpatient Care of Chemotherapy-induced Fever in Adult Haematology Patients.
France1,526 participantsStarted 2026-03
Plain-language summary
The combination of amoxicillin-clavulanate (AC) and a fluoroquinolone (FQ) is currently recommended for the treatment for outpatients with hematologic malignancies presenting with chemotherapy-induced fever (CIF), if the expected duration of neutropenia is \< 7 days. However, infections due to Pseudomonas aeruginosa (naturally resistant to AC) are rare in this population. Furthermore, FQ might result in severe adverse events, and to the selection of bacterial resistance.
The investigators hypothesize that monotherapy with AC is non-inferior to the reference treatment AC + FQ in the outpatient treatment of CIF in adult hematology patients.
Method: Pragmatic, multicentre, randomized clinical trial, controlled in two parallel groups, with stratified randomization according to the type of haematological disorder. The study will include 1,526 adult patients with one of the following haematological disorders: (1) lymphoma of all histology types treated with the goal of remission; (2) myelodysplasia treated with azacytidine; (3) acute myeloblastic leukemia receiving non-intensive care, with a basal neutrophils count \> 1000/mm3. The participants will be randomized prior to chemotherapy to receive either Amoxicillin-clavulanate 1g/152 mg tid. (AC) or Amoxicillin-clavulanate 1g/152 mg tid. and Ciprofloxacin 500 mg bid. (AC+C) orally for 7 days, to be taken in case of CIF. Only the first episode of CIF of each patient will be included in the analysis. The main evaluation criterion will be clinical success, defined as apyrexia 4 days after the first antibiotic dose, without modification of antibiotic treatment. The main secondary evaluation criteria (recorded at Day 14) will be fever recurrence, hospital admission, modification of antibiotic treatment, treatment with a beta-lactamine antibiotic efficient against P. aeruginosa, duration of antibiotic treatment, bacteraemia, inefficiency of the study treatment against the identified bacteria, and adverse events of FQ.

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.
