What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) of JNJ-42847922 | The Cmax is the maximum observed plasma concentration. | Day 1 (Pre-dose) up to Day 3 | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-last]) of JNJ-42847922 | The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time. | Day 1 (Pre-dose) up to Day 3 | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of JNJ-42847922 | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Day 1 (Pre-dose) up to Day 3 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with adverse events and serious adverse events as a measure of safety and tolerability |  | Baseline up to 10 days after last dose of study drug (Day 14) |
