A Study to Assess the Food Effect and the Relative Bioavailability of the Cabotegravir (CAB) Pediatric Dispersible Tablet (DT) Formulation

This study will assess the relative bioavailability of the CAB DT formulation relative to that of the CAB IR formulation and to assess the effect of food on the CAB DT formulation.
