Clinical trial Recruiting at 18 sites Phase 4 Interventional Ages 4 Weeks to 17

Oral switch for kids with bloodstream infections after starting IV therapy

Official title: Early Oral Switch Versus Intravenous Antibiotics in Previously Healthy Children and Adolescents With Bloodstream Infections

Run by Copenhagen University Hospital, Rigshospitalet · NCT07791914 · Data updated 2026-11-12

This trial will test whether switching from IV to oral antibiotics early is not worse than continuing IV treatment for previously healthy children and teens with uncomplicated bloodstream infections.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are previously healthy children and adolescents (4 weeks to 17 years) with uncomplicated bloodstream infections who are clinically stable and able to tolerate oral intake.

Probably not a fit

Patients with unstable infection, complicated bacteremia, or conditions requiring ongoing IV therapy may not benefit from an early oral switch.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This nationwide randomized trial in Denmark compares an early switch from intravenous to oral antibiotics to standard IV therapy in children and adolescents with uncomplicated bloodstream infections. It is a parallel-group, open-label, non-inferiority study with 1:1 randomization, stratified by pathogen group. Participants are 4 weeks to 17 years old, previously healthy, and clinically stable, recruited from 18 pediatric departments. The primary outcome is treatment failure within the study period. The study aims to provide evidence on the safety and effectiveness of oral step-down therapy in pediatric bacteremia.

Why it matters

Potential benefit: If successful, the approach could shorten hospital stays and reduce IV antibiotic exposure for pediatric patients.

How similar studies have gone: Previous adult and pediatric data suggest that short IV courses followed by oral therapy can be safe and effective, but this is among the first randomized pediatric trials to test early oral switch.

INCLUSION CRITERIA

1. Age 4 weeks to 17 years
2. Positive blood culture with a i) pathogenic bacterium (eg, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Enterobacterales, Fusobacterium spp. and other pathogenic bacteria) or ii) preliminary blood culture result (eg, Gram-negative rods or Gram-positive cocci in clusters/chains) judged by the investigator to be clinically relevant (ie, not a contaminant) and for which IV antibiotic therapy would be indicated according to standard guidelines
3. Clinical stability, defined as: (a) respiratory and haemodynamic stability, without need for oxygen, IV fluid therapy or inotropic support; and (b) well-appearing with signs of clinical improvement (eg, improved physical activity), as judged by the investigator
4. Tolerating oral fluids and diet, as judged by the investigator
5. Within the randomization window (see below)
6. Informed consent obtained from a parent or guardian, and from the patient if aged 15 years or older

Randomization window:

Randomization will take place (1) as soon as possible after eligibility is confirmed, and (2) before completion of a maximum of 4 days (96 hours) of effective IV antibiotic therapy, including the duration of the last IV dose (eg, 8 hours for penicillin and 24 hours for ceftriaxone)

EXCLUSION CRITERIA

1. Complicated infections: a. Suspicion of endocarditis (echocardiography not performed routinely), b. Suspicion of CNS infection or post-septal cellulitis, c. Foreign material (eg, bone infection involving prosthetic material). d. Complicated postoperative course (eg, perforated appendicitis)
2. Blood culture positive with a. Neisseria meningitidis, b. Streptococcus pneumoniae if afebrile within 24 hours of blood culture collection, c. bacteria considered possible contaminants (eg, coagulase-negative staphylococci, Corynebacterium spp., Micrococcus spp.)
3. Premature infants with a corrected age of less than 28 days
4. No available suitable oral antibiotic (eg, due to antimicrobial resistance or contraindications)
5. Known chronic disease associated with an increased risk of severe infection: i) Immunosuppression, e.g., chemotherapy or biological therapy predisposing to severe infections, ii) Permanent central venous catheter due to an underlying condition, iii) Severe urinary tract abnormalities predisposing to bacteremia, including children receiving prophylactic antibiotic treatment.
