Study Endpoints
Primary Endpoints
Ratio of the geometric means for the area under plasma concentration-time curve (AUC) for Tafenoquine X
Samples will be collected at Pre-dose and 1, 2, 6, 9, 12, 15, 20, 24, 36, 48, 60, and 72 hours post dose on Day 1 and single sample on Day 7, 14, 21, 28, and 56

Blood samples for PK analysis of TQ will be collected for evaluation of ratio of the geometric means (90% Confidence Interval \[CI\]) for the area under plasma concentration-time curve from 0 to time t (AUC \[0-t\]) and area under the concentration-time curve from 0 to infinity (AUC\[0-inf\]) for the treatment group dissolution profile X compared to Control.

Secondary Endpoints
Safety as assessed by clinical monitoring of blood pressure
Up to 12 hours
Safety as assessed by clinical monitoring of pulse rate
Up to 12 hours
Safety as assessed by clinical monitoring of electrocardiogram (ECGs)
