A Safety and Efficacy Study of JNJ-42165279 in Participants With Social Anxiety Disorder

This is a Phase 2a randomized (study drug assigned by chance), double-blind (neither the Investigator nor the participants know about the study intervention), placebo-controlled, parallel-group, multi-center study of JNJ-42165279 in participants with social anxiety disorder. Participants will receive 25 milligram (mg) JNJ-42165279 or matching placebo orally once-daily from Day 1 up to 12 weeks. Participants will primarily be assessed for the change from baseline in Liebowitz Social Anxiety Scale (LSAS) at Week 12. Safety will be monitored throughout the study.
