Study to Evaluate the Efficacy and Safety of Tafenoquine for the Treatment of Plasmodium Vivax in Adults

Summary

This Phase II study is designed to determine whether a single 600 mg dose or 400mg/day for 3 days of tafenoquine is efficacious, and well tolerated for clearing P. vivax malaria infection (blood schizontocidal and gametocytocidal activity) and preventing P. vivax relapse (hypnozoite eradication). It will also further establish the safety and tolerability of these doses of tafenoquine.
