The Staphylococcus aureus Network Adaptive Platform Trial is an innovative trial to evaluate a range of interventions with the aim of improving outcomes for patients with Staphylococcus aureus bacteraemia (AKA bloodstream infections).
While we have effective antibiotic treatments for S.aureus bloodstream infections, it is not known which of these are the best. There are only a few published studies that compare current available treatments and, fewer than 3,000 participants combined have ever been enrolled in published randomised controlled trials for treatments of S. aureus bloodstream infection. SNAP is a whole-of-life trial and includes both paediatric and adult participants.
There are currently four parts to the study, which we call ‘domains’. To find out more about each of these, please watch the videos below:
• Antibiotic backbone domain
• Adjunctive treatment domain (Study completed in October 2025)
• Early Oral Switch domain
• PET/CT domain
