ClinConnect Summary
This clinical trial is studying a new treatment for P. vivax malaria, a common type of malaria that can hide in the liver and cause repeated illness. Researchers want to see if a higher dose of a medication called tafenoquine (450 mg) can work well when taken with another treatment known as Artemisinin Combination Therapy (ACT). The goal is to find a more effective and convenient way to treat this malaria, especially since the current treatments can take a long time and may not work as well in some cases.
To be eligible for the trial, participants must be at least 18 years old, weigh more than 35 kg, and have been diagnosed with P. vivax malaria. They should also have had a fever recently and meet certain health criteria related to a specific blood enzyme. Participants will need to be willing to follow the study guidelines for about four months. In this trial, individuals can expect to receive close monitoring of their health and the chance to contribute to research that may improve malaria treatment options in the future.
