Experimental
JNJ-77242113 		Adolescent and adult participants will receive JNJ-77242113 from Week 0 through Week 156. At Week 24, adult participants who are psoriasis area and severity index (PASI) 75 or investigator global assessment (IGA) score of 0 or 1 responders (that is, those who achieve an IGA score of 0 or 1 and have >=2-grade improvement from baseline) will be re-randomized either to continue JNJ-77242113 or to placebo (and will be retreated with JNJ-77242113 upon loss of >=50% of their Week 24 PASI improvement). Adult participants identified as both PASI 75 and IGA 0 or 1 score non-responders will continue to receive JNJ-77242113 through Week 52. From Week 52 to Week 156, all adult participants will receive JNJ-77242113. Adolescents will not participate in re-randomization regardless of their PASI score or IGA score at Week 24. Adolescents will continue to receive JNJ-77242113 from Week 0 through Week 156.
