Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the rate and extent of absorption of JNJ63623872 following administration of a single oral dose of 2*300 milligram (mg) given as 2 concept single agent tablet formulations compared to the administration of 2*300 mg JNJ63623872 reference tablets, under fasted conditions in healthy adult participants and to assess the rate and extent of absorption of JNJ63623872 and oseltamivir following administration of a single oral dose of 2*300 mg/37.5 mg JNJ63623872/ oseltamivir given as a concept fixed dose combination (FDC) tablet formulation compared to the coadministration of 2*300 mg JNJ63623872 tablets (reference formulation) and 1*75 mg oseltamivir capsule, under fasted conditions in healthy adult participants.

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adverse Events (AEs) | Safety and Tolerability | Up to follow-up (within 10 to 14 days after last dose) | 
| Taste Questionnaire Assessment | A taste questionnaire will be completed by the participants of Panel 2, group 7 within 5 to 15 minutes after intake of the FDC tablet (Treatment E) to evaluate the taste of the oral FDC tablet formulation under fasted conditions. The Taste questionnaire consists of 4 parts (sweetness, bitterness, flavour and overall); each parts is scored on 4 points , i.e. none, weak, moderate and strong. | Day 1 | 
| Swallowability Assessment | Swallowability will be assessed in participants of Panel 2 group 7 on a scale of 1-7; how difficult/easy was it to swallow this tablet. In the scale 0=very difficult and 7=very easy. | Day 1 |
