- People aged 18 or older
- People who have had a heart tracing test (ECG) done within the 60 days before joining the trial

- People taking certain other medications with a lower but possible risk of affecting heart rhythm (such as ondansetron or SSRIs) may be excluded if a heart tracing done within 24–48 hours of starting two of the study drugs shows a significant heart rhythm change (confirm with trial site)
- People with a history of a specific type of liver or jaundice problem linked to a particular antibiotic (amoxicillin-clavulanate)
- People with moderate to severe active liver disease, or active liver disease with significantly abnormal liver test results
- People with a history of the muscle condition myasthenia gravis
