Antibiotics or sugar pill? new study questions need for drugs in Kids' pneumonia
NCT ID NCT06325293
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether children with pneumonia caused by Mycoplasma bacteria need antibiotics to get better. About 376 children aged 3-17 will receive either a placebo (inactive pill) or a common antibiotic. Researchers will track how long symptoms like fever and fast breathing last, and whether any children need extra hospital care. The goal is to see if antibiotics are truly necessary for recovery.

Inclusion criteria for screening phase: * Children aged 3-17 years (from 3rd up to 18th birthday) presenting to the emergency department (ED) who will be managed ambulatory or will be admitted to general ward. * Clinical diagnosis of CAP: 1. Diagnosis defined as the treating physician's documented diagnosis of CAP; AND 2. Fever ≥38.0°C (measured by any method \[i.e., ear, axillary, rectal, or forehead site\] in the ED or via parent report observed in the last 24h); AND 3. Tachypnea (defined as respiratory rate (RR) above age-specific reference value) during the assessment in ED (triage or clinical examination). * Written screening consent for participation in screening phase signed by parents/legal guardians and the patient if ≥14 years of age. Additional inclusion criteria for intervention phase: * Positive Mp screening test result with the Mp IgM lateral flow assay (LFA) (grade 2 or 3). * Written informed consent for participation in intervention phase signed by parents or legal guardians and the patient if ≥14 years of age. Exclusion criteria: Exclusion criteria for screening phase: • None. Exclusion criteria for intervention phase: * Contraindication to azithromycin: Documented allergy to azithromycin; cardiovascular disease, including bradycardia, arrhythmias, and/or QT-interval prolongation\*; myasthenia gravis. \*Co-medication with arrhythmogenic or QT-interval-prolonging drug (www.qtdrugs.org) is no exclusion criteria but will be discussed with the local investigators and/or trial management team (TMT). * Underlying comorbidities: Cystic fibrosis or other chronic lung disorders (excluding asthma), primary or secondary immunodeficiency, sickle-cell anemia, or severe cerebral palsy. * History of recurrent pneumonia (two or more episodes) or severe pneumonia (ICU admission or complications of CAP such as lung abscess, effusion, and empyema) in lifetime. * Antibiotic treatment against Mp within the previous 7 days, including macrolides, tetracyclines, or fluoroquinolones. * Referral to ICU directly from the ED. * Inability to take oral medication. * Parents are unlikely to reliably complete follow up (FUP) visits and questionnaires (e.g., due to language barriers or living far from the study site).
