A Study to Assess the Relative Oral Bioavailability of a Single Dose of JNJ-53718678 Administered as Oral Concept Formulation Compared to the Current Oral Solution and to Assess the Effect of Food on the Pharmacokinetics of Oral Concept Formulation

The purpose of this study is to assess the relative bioavailability of 1 to 3 concept formulations of JNJ-53718678 compared to the currently existing oral solution, and to assess the effect of food on the bioavailability of 1 to 3 oral concept formulations of JNJ-53718678 when administered as a single oral dose of 500 milligram (mg) in healthy adult participants.
