Summary

This study looks at whether a malaria drug called tafenoquine interacts with two other common malaria treatments (DHA-piperaquine and artesunate-pyronaridine) in adults with vivax malaria. About 507 participants will receive one of the combinations or a delayed treatment to compare safety and how well they prevent the parasite from returning. The goal is to find the best way to combine these drugs for effective malaria control.
