Efficacy of SJ733 in Adults With Uncomplicated Plasmodium Falciparum or Vivax Malaria

Summary

This Phase 2a trial recruits adult patients with uncomplicated P. vivax or P. falciparum blood-stage malaria mono-infection. The study drug SJ733 will be administered to examine its antimalarial efficacy, safety, and tolerability. This study also evaluates whether or not a fixed dose of the pharmacoenhancer cobicistat when given in combination with SJ733 significantly improves drug efficacy.
