Could a simple pill replace the needle for kids with bone infections?
NCT ID NCT04538053
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether giving children with bone and joint infections antibiotics only by mouth works just as well as starting with IV antibiotics for a few days and then switching to pills. About 285 children aged 1 to 18 from hospitals in Australia and New Zealand will take part. The goal is to see if the simpler oral-only approach leads to full recovery after 3 months.
