Meliodosis | Co-trimoxazole as Maintenance Therapy for Meliodosis

Meliodosis research study

What is the primary objective of this study?

This is a randomised, open-labelled, controlled trial to compare the efficacy and effectiveness on relapse-free rate of 12-week versus 20-week oral eradication treatment of melioidosis. The study population includes 800 patients with culture-confirmed melioidosis whom 12 weeks of oral eradication therapy have been completed with or without intravenous intensive antibiotics. Patients will be randomised to either stop the eradication treatment or continue current oral treatment for 8 more weeks. The study aim to optimise the regimen used to treat melioidosis for better compliance and reducing unnecessary use of antibiotics.
