  Purpose
The malaria parasite Plasmodium falciparum remains at sub-patent level throughout the dry season in areas of seasonal malaria transmission. Targeting this parasite reservoir before the transmission season could be a good strategy for malaria control. We are conducting a randomized double blind placebo controlled mass drug administration trial in eight village to clear the dry season low level parasitaemia with an ultimate aim of controlling malaria in eastern Sudan.

Condition Intervention Phase
Plasmodium Falciparum Asymptomatic Parataemia Sub Patent Parasitaemia Drug: Sulfadoxine / Pyrimethamine (SP) plus artesunate (AS) Drug: placebo tablet similar to active drug in shape and size Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Validation of the Use of Istope-Based Molecular Techniques for Malaria Control
