Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi- centre trial of children with bone and joint infections (BJIs) at eight major paediatric hospitals in Australia and New Zealand. The primary objective is to establish if in children with acute, uncomplicated BJIs, entirely oral antibiotic treatment is not inferior to initial intravenous (IV) treatment for 1 to 7 days followed by an oral antibiotic course in achieving full recovery 3 months after presentation. Children will be randomly allocated to the 'entirely oral antibiotic' group or the 'standard treatment' group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Children with acute onset BJIs who present to the participating sites will be enrolled into the trial if eligible (see eligibility criteria) and randomly allocated into two groups. Children in the 'standard treatment group' will receive standard treatment for BJIs, which consists of IV antibiotics for 1-7 days followed by 3 weeks of oral antibiotics. Children in the 'entirely oral treatment group' will receive high dose oral antibiotics, followed by the standard dose of oral antibiotics for 3 weeks. The outcomes of children in each of the two groups will be compared to determine whether BJIs can be treated without needing a course of IV antibiotics.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Children aged 1 to 18 years with acute, uncomplicated, community-acquired bone and joint infection who fulfil pre-defined clinical criteria.

Exclusion Criteria

1. Infection due to bacteria resistant to cefalexin or atypical infection (e.g. mycobacterial, fungal)
2. Features of sepsis as defined by the presence of organ dysfunction (defined using definitions within the Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score)
3. Concomitant severe, invasive infection e.g. necrosing fasciitis
4. Complicated infection (e.g. presence of prosthetic material; large subperiosteal (\>3mm) or soft tissue abscess without surgical intervention; infection secondary to or complicated by trauma)
5. History of allergy to cephalosporin antibiotics or immediate, severe reaction to penicillins
6. Received more than three IV or oral dose of an antibiotic with activity against the likely bacteria causing the current infection
7. Prior episode of OM or SA
8. Prior condition predisposing to poor absorption (e.g. inflammatory bowel disease, current gastrointestinal symptoms) or complicated disease (e.g. immunodeficiency)
9. Prior enrolment in the trial
10. Current recipient of another investigational product as part of a clinical trial
