Hydrochloric Acid Lock Therapy for Central Line-associated Bloodstream Infections
Denmark212 participantsStarted 2022-06-01
Plain-language summary
Aim: This study will test whether treatment of central line-associated bloodstream infections (CLABSI) with hydrochloric acid lock therapy (HALT) can significantly reduce the risk of treatment failure (comprising failure to clear initial infection, relapse of infection, or reinfection) in patients treated for cancer or hematologic diseases.
Study design: A multicentre, double-blinded, randomized controlled trial. Patient population: Patients (0-100 y) with cancer or a hematologic disorder and a CLABSI treated at Copenhagen University Hospital, Aarhus University Hospital, or Odense University Hospital, Denmark.
Randomization: Patients are equally assigned (1:1) to receive either HALT or placebo (normal saline). In addition to the study intervention, patients in both arms will receive standard systemic antibiotic therapy.
Sample size: A target population of 250 patients

Inclusion criteria
* Patients aged 0-17 years treated at pediatric oncologic department at Copenhagen University Hospital, Odense University Hospital, and Aarhus University Hospital, Denmark. Inclusion of children and adolescents from 1st of June 2022.
* Patients aged 18-100 years treated at Department of Hematology, Copenhagen University Hospital, Denmark. Inclusion of adult patients from 17th of October 2023.
* Patients receiving treatment for cancer or a hematologic disease (any type and at any point in the course of the disease).
* CVAD in situ (intravenous ports and all central lines).
* New diagnosis of CLABSI (defined as a laboratory-confirmed bloodstream infection, not secondary to infection at another site, in a patient who has a CVAD). NB, patients who had a CLABSI prior to the beginning of the study are accepted for enrollment if they have a new CLABSI during the patient enrollment phase.
The patient is followed 6 weeks from instillation with HALT/placebo. The patient can be re-included if the patient has 1) replacement of the CVAD, or 2) a new CLABSI later than 6 weeks from a previous CLABSI. In case of re-inclusion the patient, the patient will be randomized again.
Exclusion Criteria:
* Plan to remove CVAD within 6 days.
* Instantly admission to Intensive Care Uni
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.
What they're measuring
1
Treatment failure.
Timeframe: Within 6 weeks after HALT or placebo (normal saline) treatment of the CVAD.
