Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An observational cohort and malaria treatment study in Cambodia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an active observational Cohort Study of malaria epidemiology with a nested two arm, randomized, open label Treatment Study comparing the efficacy, safety, tolerability and pharmacokinetics of a two versus three day course of Dihydroartemisinin-Piperaquine (DP) for those developing uncomplicated malaria. At the conclusion of the Cohort Study, a subset of volunteers with documented exposure to Plasmodium vivax during the study will be treated with primaquine as presumptive anti-relapse therapy directed against the exoerythrocytic malaria stages of P. vivax, and followed passively for an additional 6 months.
