Official title FocaL Mass Drug Administration for Vivax Malaria Elimination
ClinicalTrials.gov ID: NCT05690841
What this study is testing
What is Focal Mass Drug Administration (fMDA)?
Focal Mass Drug Administration (fMDA) is an investigational medicine, being studied as a potential treatment for plasmodium vivax malaria.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- FLAME is an open-label cluster-randomized controlled trial that aims to determine the effectiveness of focal mass drug administration (fMDA) to reduce the incidence of Plasmodium vivax malaria in the Loreto Department in Peru. Standard interventions, including symptomatic and asymptomatic screening for malaria infections, provision of insecticide-treated bednets, and environmental transmission monitoring, will be compared to clusters of villages randomized to receive anti-malarial drugs.
- Phase 3: a large, late-stage study
