All compounds are either investigational or being studied for (a) new use(s). Efficacy and safety have not been established. There is no guarantee that they will become commercially available for the use(s) under investigation. 

Study Description

The study will assess the effect of multiple doses of itraconazole, a strong CYP3A4/5 inhibitor, on the PK of ganaplacide and lumefantrine in healthy participants. This study will provide data that is relevant for advice regarding possible concomitant medications that are inhibitors of CYP3A4/5 in future clinical studies with ganaplacide and lumefantrine and for potential future labeling considerations
